BACKGROUND: Several studies investigated circulating levels of serotonin (5-HT) and brain-derived neurotrophic factor (BDNF) in children with Autism spectrum disorder (ASD). More limited literature focused on ASD adults or on populations with subthreshold autism spectrum manifestations, such as relatives of ASD probands. This study aimed to investigate 5-HT and BDNF levels in adults with autism spectrum conditions. Correlations between levels of biochemical variables and ASD symptoms were also evaluated. METHOD: a sample of ASD adults, their first-degree relatives (Broad autism phenotype, BAP group), and controls were recruited and assessed with psychometric scales. Blood samples were collected from all participants. 5-HT and BDNF levels were measured by means of ELISA kits. RESULTS: ASD adults showed significantly lower platelet-poor plasma (PPP) 5-HT levels than BAP and control groups. No significant difference was found among groups for PPP BDNF levels and intra-platelet 5-HT levels. 5-HT levels were reported to be specifically correlated with some autism symptoms. CONCLUSION: This work highlighted the presence in ASD adults of reduced PPP 5-HT levels than in other groups, without significant differences with respect to BDNF levels, supporting the hypothesis that biochemical correlates of ASD in adults may be different from those typically reported in children.

Proteolysis-targeting chimeras (PROTACs) are an attractive means to target previously undruggable or drug-resistant mutant proteins. While small molecule-based PROTACs are stable and can cross cell membranes, there is limited availability of suitable small molecule warheads capable of recruiting proteins to an E3 ubiquitin ligase for degradation. With advances in structural biology and in silico protein structure prediction, it is now becoming easier to define highly selective peptides suitable for PROTAC design. As a result, peptide-based PROTACs are becoming a feasible proposition for targeting previously "undruggable" proteins not amenable to small molecule inhibition. In this review, we summarize recent progress in the design and application of peptide-based PROTACs as well as several practical approaches for obtaining candidate peptides for PROTACs. We also discuss the major hurdles preventing the translation of peptide-based PROTACs from bench to bedside, such as their delivery and bioavailability, with the aim of stimulating discussion about how best to accelerate the clinical development of peptide-based PROTACs in the near future.

The reproductive system is extremely vulnerable to chemotherapy drugs, ionizing radiation, toxic heavy metals, chemicals, and so on. These harmful stimuli are able to induce oxidative damage, apoptosis, inflammation, and other mechanisms in the reproductive organs, leading to different adverse reproductive effects. It was shown that using medicinal plants (medicinal herbs) can be an effective medication for the prevention and treatment of multiple health conditions. Silymarin is a medicinal herb extract, obtained from the seeds of Silybum marianum. This herbal agent is a nontoxic agent even at relatively high physiological dose values, which suggests that it is safe for use in the treatment of different diseases. The hepato-, neuro-, cardio- and nephro-protective effects of silymarin have been assessed previously. The protective activities of silymarin can point to anti-oxidant, anti-apoptotic, anti-inflammatory, anti-fibrotic, immunomodulatory, and membrane-stabilizing properties. In this review, we aim to summarize current studies on the protective potentials of silymarin against reproductive toxicity. The molecular mechanisms of silymarin protection against cellular toxicity are also studied. Moreover, the findings obtained from improved formulations and delivery systems of silymarin have been addressed.

Cancer bears a significant share of global mortality. The enzyme Lysine Specific Demethylase 1 (LSD1, also known as KDM1A), since its discovery in 2004, has captured the attention of cancer researchers due to its overexpression in several cancers like acute myeloid leukaemia (AML), solid tumours, etc. The Lysine Specific Demethylase (LSD1) downregulation is reported to have an effect on cancer proliferation, migration, and invasion. Therefore, research to discover safer and more potent LSD1 inhibitors can pave the way for the development of better cancer therapeutics. These efforts have resulted in the synthesis of many types of derivatives containing diverse structural nuclei. The present manuscript describes the role of Lysine Specific Demethylase 1 (LSD1) in carcinogenesis, reviews the LSD1 inhibitors explored in the past five years and discusses their comprehensive structural activity characteristics apart from the thorough description of LSD1. Besides, the potential challenges, opportunities, and future perspectives in the development of LSD1 inhibitors are also discussed. The review suggests that tranylcypromine derivatives are the most promising potent LSD1 inhibitors, followed by triazole and pyrimidine derivatives with IC50 values in the nanomolar and sub-micromolar range. A number of potent LSD1 inhibitors derived from natural sources like resveratrol, protoberberine alkaloids, curcumin, etc. are also discussed. The structural-activity relationships discussed in the manuscript can be exploited to design potent and relatively safer LSD1 inhibitors as anticancer agents.

Hydrogen sulfide (H2S) is an endogenous gaseous molecule present in all living organisms and has been traditionally studied for its toxicity. Interestingly, increased understanding of H2S effects in organ physiology has recently shown its relevance as a signalling molecule, with potentially important implications in variety of clinical disorders, including cancer. H2S is primarily produced in mammalian cells under various enzymatic pathways. A developing focus of H2S is a blooming hotspot that studies chemical, biological mechanisms, and therapeutic effects of H2S. Herein, we describe the physiological and biochemical properties of H2S, the enzymatic pathways leading to its endogenous production and its catabolic routes. In addition, we discuss the role of currently known H2S-releasing agents, or H2S donors, including their potential as therapeutic tools. Then we illustrate the mechanisms known to support the pleiotropic effects of H2S, with a particular focus on persulfhydration, which plays a key role in H2S-mediating signalling pathways. We then address the paradoxical role played by H2S in tumour biology and discuss the potential of exploiting H2S levels as novel cancer biomarkers and diagnostic tools. Finally, we describe the most recent preclinical applications focused on assessing the anti-cancer impact of most common H2S-releasing compounds. While the evidence in favour of H2S as an alternative cancer therapy in the field of translational medicine is yet to be clearly provided, application of H2S is emerging as potent anticancer therapies in preclinical trails.

Alzheimer's disease (AD) is a neurodegenerative disease that seriously affects the health and quality of life of the elderly. Its pathogenesis is very complex and there is still a lack of effective clinical drugs to treat or control the development of AD. Studies have shown that β-amyloid (Aβ) deposition, tau protein hyperphosphorylation, reduced levels of brain cholinergic transmitters, and oxidative stress are the main causes of AD. Furthermore, recent studies showed that metal dyshomeostasis could relate to all the above pathogenesis of AD and was a key factor in the development of AD. Natural compounds and their derivatives have multi-target therapeutic effects on AD, and they also have the advantages of low toxicity, and low cost, which are important directions for anti-AD drugs. Meanwhile, early detection may play an important role in in preventing the development of AD. The concept of "theranostic agent" combining molecular imaging probes and therapeutic drugs has emerged in recent years. Fluorescence imaging has been widely studied and applied because of its non-invasive, high resolution, high sensitivity, rapid imaging, and low cost. However, at present, most of the research methods in this field use individual therapeutic or diagnostic reagents, which is not conducive to exploring the optimal treatment time window and drug efficacy. Therefore, this work reviewed the natural compounds and their derivatives which all have been studied for both the in vitro and in vivo therapeutic and diagnostic anti-AD activities. At last, structure and activity relationship (SAR) was discussed and potential AD theranostic natural agents were put forwarded to provide a more detailed theoretical basis for the further development of drugs with diagnostic and therapeutic effects in AD.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a member of the coronavirus family and could induce the viral disease named coronavirus disease 2019 (COVID-19). The disease became a pandemic after the reported first case in December 2019. In this review, we highlighted the herbal substances with antiviral effects. To examine peer-review publications dealing with the features and prospects for COVID-19 treatment with an emphasis on pro-inflammatory cytokines, we conducted electronic and full-text searches of Science Direct, CABI Direct, Web of Science, PubMed, and Scopus databases. Cytokine storm mechanisms are factors that induce a pro-inflammatory response, including the expression of cytokines and chemokines. The subsequent leukocyte recruitment and antiviral effect or functions contribute to the first line of defense against viruses. There have been numerous investigations with herbal medicine candidates used as immunomodulators or antivirals. However, cytokine-storm-targeted therapy was recommended to SARS-CoV patients with acute respiratory distress syndrome leading to severe pulmonary failure. These reviews showed that herbal formulations as alternative medicine might significantly reduce complicated viral infections and hold promising specific antiviral on experimental animal models.

BACKGROUND: Long chain non-coding RNAs (lncRNA) are a kind of transcript that is around 200 nucleotides long and can engage in life activities via epigenetic, transcriptional, and post-transcriptional regulation. One of the key members of lncRNAs, long stress-induced noncoding transcripts 5 (LSINCT5), is localized at Chr 5p and has been reported to be abnormally expressed in a range of cancers. We present a comprehensive review of LSINCT5's aberrant expression and regulatory mechanisms in malignant tumors. METHOD: The included studies were retrieved and summarized through the PubMed database using the keywords "LSINCT5" and "Cancer" in detail. RESULTS: LSINCT5 behaves as an oncogene and abundantly expresses in malignant tumorigenesis and progression. By sponging microRNAs (miRNA), interacting with proteins, participating in cellular transduction, and being regulated by transcription factors, LSINCT5 can stimulate malignant behavior in a variety of tumor cells, including proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT). Furthermore, dysregulated LSINCT5 is usually associated with a poor prognosis. CONCLUSION: LSINCT5 has the potential to become a tumor diagnostic and prognostic marker, generating new access to clinical applications.

BACKGROUND: With the emergence of drug-resistant bacteria, the development of new antibiotics is urgently required. Target-based drug discovery is the most frequently employed approach for the drug development process. However, traditional drug target identification techniques are costly and time-consuming. As research continues, innovative approaches for antibacterial target identification have been developed which enabled us to discover drug targets more easily and quickly. METHODS: In this review, methods for finding drug targets from omics databases have been discussed in detail including principles, procedures, advantages, and potential limitations. The role of phage-driven and bacterial cytological profiling approaches is also discussed. Moreover, current article demonstrates the advancements being made in the establishment of computational tools, machine learning algorithms, and databases for antibacterial target identification. RESULTS: Bacterial drug targets successfully identified by employing these aforementioned techniques are described as well. CONCLUSION: The goal of this review is to attract the interest of synthetic chemists, biologists, and computational researchers to discuss and improve these methods for easier and quicker development of new drugs.

BACKGROUND: The representative symptom of Alzheimer's Disease (AD) has mainly been mentioned to be misfolding of amyloid proteins, such as amyloid-beta (Aβ) and tau protein. In addition, the neurological pathology related to neuroinflammatory signaling has recently been raised as an important feature in AD. Currently, numerous drug candidates continue to be investigated to reduce symptoms of AD, including amyloid proteins misfolding and neuroinflammation. OBJECTIVE: Our research aimed to identify the anti-AD effects of two chemical derivatives modified from cromoglicic acid, CNU 010 and CNU 011. METHODS: CNU 010 and CNU 011 derived from cromoglicic acid were synthesized. The inhibitory effects of Aβ and tau were identified by thioflavin T assay. Moreover, western blots were conducted with derivates CNU 010 and CNU 011 to confirm the effects on inflammation. RESULTS: CNU 010 and CNU 011 significantly inhibited the aggregation of Aβ and tau proteins. Moreover, they reduced the expression levels of mitogen-activated protein (MAP) kinase and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling proteins, which are representative early inflammatory signaling markers. Also, the inhibitory effects on the lipopolysaccharide (LPS)-induced cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) expression referring to late inflammation were confirmed. CONCLUSION: Our results showing multiple beneficial effects of cromolyn derivatives against abnormal aggregation of amyloid proteins and neuroinflammatory signaling provide evidence that CNU 010 and CNU 011 could be further developed as potential drug candidates for AD treatment.

BACKGROUND: NLS-3 or (R, R) enantiomer of phacetoperane (levophacetoperane) is the reverse ester of methylphenidate, a well-documented psychostimulant marketed for the treatment of attention-deficit/hyperactivity disorder (ADHD) since the end of 1950s. Launched in Canada and Europe by Specia Rhône-Poulenc and Rhodia, marketed as Lidepran® (8228 R.P.), for the treatment of obesity and depression, phacetoperane became an increasingly popular psychiatric medication from 1959 to 1967. Previous data supported that the stimulant effect of phacetoperane differed from those of other medications acting on the catecholamine system (e.g., methylphenidate, amphetamine), with an advantage of benefit/risk balance. METHOD: The goal of this study is to characterize the binding profile of NLS-3 using in vitro and in vivo assays and hypothesize potential therapeutic uses considering all available data. RESULTS: A complete binding profile assay confirmed the potential benefit of phacetoperane with a higher benefit/risk compared to other stimulants. NLS-3 synthesis resulted from phenylketone, which is also used for the synthesis of methylphenidate. It differs from that used by Rhône-Poulenc SA laboratories, allowing the possibility of individualizing several enantiomers not synthesized previously. The present review also confirmed extensive clinical use of the compound in almost one thousand children and adolescents in large dose ranges with fewer side effects versus comparative treatments. Furthermore, levophacetoperane was found to be generally well-tolerated by the subjects. CONCLUSION: NLS-3 could be a safer and more potent alternative to stimulants for patients with ADHD.

Leishmaniasis is a neglected disease caused by the parasite of the genus Leishmania. Current treatment regimens are obsolete and cause several side effects, promoting poor patient compliance, in addition to the vast majority already having the potential for resistance. Therefore, polymeric nanoparticles emerge as one of the viable alternatives to overcome existing limitations, through passive or active vectorization. This review aims to summarize the latest studies of polymeric nanoparticles as an alternative treatment for leishmaniasis. In the first section, the main pharmacokinetic and pharmacodynamic challenges of current drugs are reported. The second section details how nanoparticles with and without functionalization are efficient in the treatment of leishmaniasis, discussing the characteristics of the polymer in the formulation. In this way, polymeric nanoparticles can improve the physicochemical properties of leishmanicidal drugs, improving solubility and stability, as well as improve the release of these drugs, directly or indirectly reaching monocytes/macrophages. 64.28% drugs were focused on the treatment of visceral leishmaniasis, and 28.57% on cutaneous leishmaniasis. The most chosen polymers in the literature are chitosan (35.71%) and PLGA (35.71%), the others represented 14.30% drugs, with all able to manage the drug release and increase the in vitro and/or in vivo efficacy of the original molecule. However, there are several barriers for these nanoformulations to cross laboratory research and is necessary more in-depth studies about the metabolites and degradation pathways of the polymers used in the formulations and plasma proteomics studies.

BACKGROUND: Compounds that target tumor epigenetic events are likely to constitute a prominent strategy for anticancer treatment. Histone deacetylase inhibitors (HDACis) have been developed as prospective candidates in anticancer drug development, and currently, many of them are under clinical investigation. We assessed the anticancer efficacy of a now hydroxamate-based HDACi, YF-343, in triple-negative breast cancer development and studied its potential mechanisms. METHODS: YF-343 was estimated as a novel HDACi by the HDACi drug screening kit. The biological effects of YF-343 in a panel of breast cancer cell lines were analyzed by Western blot and flow cytometry. YF-343 exhibited notable cytotoxicity, promoted apoptosis, and induced cell cycle arrest. Furthermore, it also induced autophagy, which plays a pro-survival role in breast cancer cells. RESULTS: The combination of YF-343 with an autophagy inhibitor chloroquine (CQ) significantly suppressed breast tumor progression as compared to the YF-343 treatment alone both in vitro and in vivo. Mechanistically, the molecular mechanism of YF-343 on autophagy was elucidated by gene chip expression profiles, qPCR analysis, luciferase reporter gene assay, chromatin immunoprecipitation assays, immunohistochemical analysis, and other methods. E2F7, a transcription factor, promoted the expression of ATG2A via binding to the ATG2A promoter region and then induced autophagy in triple-negative breast cancer cells treated with YF-343. CONCLUSION: Our studies have illustrated the mechanisms for potential action of YF-343 on tumor growth in breast cancer models with pro-survival autophagy. The combination therapy of YF-343 and CQ maybe a promising strategy for breast cancer therapy.

According to the 2017 ILAE's official definition, epilepsy is a slow brain disease state characterized by recurrent episodes. Due to information released by ILAE in 2017, it can be divided into four types, including focal epilepsy, generalized epilepsy, combined generalized, and focal epilepsy, and unknown epilepsy. Since 1989, 24 new antiepileptic drugs have been approved to treat different types of epilepsy. Besides, there are a variety of antiepileptic medications under clinical monitoring. These novel antiepileptic drugs have plenty of advantages. Over the past 33 years, there have been many antiepileptic drugs on the mearket, but no one has been found that can completely cure epilepsy. In this paper, the mentioned drugs were classified according to their targets, and the essential information, and clinical studies of each drug were described. The structure-activity relationship of different chemical structures was summarized. This paper provides help for the follow-up research on epilepsy drugs.

In recent years, the scientific community has been trying to tackle different diseases by using unifying and holistic approaches based on the concept that it is possible to target apparently very different diseases under a comprehensive general scheme. In other words, various different diseases have been grouped together under the label of "conformational diseases", because the triggering cause for each malady is the misfolding of a specific protein, whose dyshomeostasis and accumulation cause all the other downhill biomolecular events characteristic of each different disease. In a parallel manner, analytical techniques have developed to investigate protein misfolding and accumulation, so as to give a valid technical support to the investigation of conformational diseases. In this scenario, surface plasmon resonance (SPR) has widely contributed to study many different aspects correlated to conformational diseases, offering the advantages of real time investigations, use of small amounts of biological materials and possibility to mimic the cellular environments without recurring to the use of fluorescent tags. In this review, after a brief introduction about conformational diseases and the SPR technique, a thorough description of the various uses of SPR to investigate the biomolecular mechanisms involved in these diseases is given in order to provide the reader with an exhaustive list as well as a critical perspective of the use of SPR for such topic. The case of Alzheimer's disease is discussed at a deeper level. We hope that this work will make the reader aware of all the possible SPR experimental approaches, which can be used to develop new possible therapeutic strategies to tackle conformational diseases.

Matrix metalloproteinases (MMPs) are a family of zinc-containing proteases that participate in many physiological and pathological processes in vivo. Recently, the MMP network has been established according to a deeper understanding of its functions. Some MMPs have been also regarded as biomarkers of various diseases, including inflammation, nerve diseases, and cancers. MMP labelling has been thus paid more attention in recent decades. Accordingly, both reagents and technologies for MMP labelling have been rapidly developed. Here we summarize the recent development of some MMP labelling methods. This review was identified through keyword (MMPs; labelling; etc.) searches in the ScienceDirect database, Scifinder, Web of Science, and PubMed for which typical cases were used for an inductive overview. In spite of the advances in MMP labelling, selective labelling of a specific MMP is still an open issue. We hope that this article can be helpful in developing specific MMP labelling methods in future.

The epicardial adipose tissue, which is referred to as fats surrounding the myocardium, is an active organ able to induce cardiovascular problems in pathophysiologic conditions through several pathways, such as inflammation, fibrosis, fat infiltration, and electrophysiologic problems. So, control of its volume and thickness, especially in patients with diabetes, is highly important. Incretin-based pharmacologic agents are newly developed antidiabetics that could provide further cardiovascular benefits through control and modulating epicardial adiposity. They can reduce cardiovascular risks by rapidly reducing epicardial adipose tissues, improving cardiac efficiency. We are at the first steps of a long way, but current evidence demonstrates the sum of possible mechanisms. In this study, we evaluate epicardial adiposity in physiologic and pathologic states and the impact of incretin-based drugs.

G protein-coupled receptors (GPCRs) represent a large superfamily of cell-surface proteins that mediate cell signaling and regulate virtually various aspects of physiological and pathological processes, therefore serving as a rich source of drug targets. As intrinsically allosteric proteins, numerous functions of GPCRs are regulated via allostery, whereby allosteric modulators binding at a distal site regulate the function of the typical orthosteric site. However, only a few GPCR allosteric ligands have been presently approved as drugs due to the high dynamic structures of GPCRs. Fortunately, the rapid development of computational biology sheds light on understanding the mechanism of GPCR allosteric ligands, which is critical for the discovery of new therapeutic agents. Here, we present a comprehensive overview of the currently available resources and approaches in computational biology related to G protein-coupled receptor allostery and their conformational dynamics. In addition, current limitations and major challenges in the field are also discussed accordingly.

BACKGROUND: Lipopolysaccharide (LPS) is an endotoxin that causes inflammation, and the content of LPS increases gradually during the process of aging. Whether the response of the colon to LPS stimulation will increase with age is yet unknown. OBJECTIVE: The study investigated the effects of LPS stimulation on the colon of adult and aging rats. METHOD: 43 healthy male SD rats were divided into 4 different groups: adult group and LPS-stimulated adult group at the age of 4 months, and aging group and LPS-stimulated aging group at the age of 22 months. Rats were stimulated by intraperitoneal injection of LPS (1mg/kg) for 24 h. The morphological changes of the colon were observed, and intestinal inflammatory response, tight junction proteins, apoptosis, and proliferation in intestinal epithelial cells were detected. RESULTS: A series of morphology changes occurred in the colon of adult rats after LPS stimulation, the higher inflammatory response (TLR4, NF-κB, and IL-1β), changes in the protein levels of tight junctions (ZO-1, Claudin1, and Claudin2), and increased apoptosis (Bax, Bcl2) and proliferation (PCNA) of intestinal epithelial cells. The above changes were also found in aging rats. LPS stimulation further promotes the above changes to some extent in the colon of aging rats. CONCLUSION: A series of colon changes in rats was significantly damaged during LPS stimulation and aging, and these changes were further aggravated to some extent in LPS-stimulated aging rats.

BACKGROUND: NR2F1-AS1 is a long non-coding RNA (lnc RNA) that is involved in different biological processes. It plays an integral role in the pathophysiology of human diseases, especially tumorigenesis and progression. Therefore, it may be a promising target for numerous tumor biotherapeutics. The current review study aimed to show the pathophysiological activities and processes of RNA NR2F1-AS1 in cancer cells. METHODS: The contents of the present review were based on information obtained from PubMed. In the data search, "NR2F1-AS1" was chosen as the first keyword, whereas "cancer" was chosen as the second keyword. This review selected and summarized studies published between 2019-2021, concerning the biological functions and mechanisms of NR2F1-AS1 in the development of tumorigenesis. RESULTS: It was found that NR2F1-AS1 regulates a variety of biological activities such as proliferation, invasion, migration, and apoptosis. It acts as an oncogene because it is abnormally expressed and promotes the progression of cancer in a variety of malignancies, including esophageal squamous cell carcinoma, non-small cell lung cancer, breast cancer, neuroblastoma, endometrial cancer, thyroid cancer, and gastric cancer. However, it was evident that NR2F1-AS1 inhibits the progression of cancer in cervical squamous cell carcinoma. CONCLUSION: NR2F1-AS1 is a potential new biomarker and therapeutic target for the treatment of different cancers.

Gastrointestinal (GI) cancers are one of the most common human malignancies and a leading cause of morbidity and mortality worldwide. One of the most prominent hallmarks of cancer and a basic trait of almost all GI malignancies is genomic/epigenomics alterations. DNA methylation is highlighted as a fundamental mechanism underlying the inactivation of several tumor-suppressor gene signaling pathways. Thus, sites of DNA methylation can be triggered for cancer therapy. Available therapeutic procedures for GI cancer show unsatisfactory efficacy, and some treatments are associated with severe side effects, including ulceration or bleeding. Therefore, it is essential to find alternative treatments. There is growing evidence indicating that some chemopreventive phytochemicals can combat cancer. One of the most systematically investigated nutraceuticals for its advantages in managing different diseases is curcumin (CUR). CUR is well known for its potent anticancer characteristics by targeting epigenetic mechanisms, with DNA methylation at the forefront. Prior investigations have indicated that CUR treatment can benefit GI cancers by controlling several signaling pathways related to oxidative stress and epigenomics pathways. The present literature displays recent evidence regarding DNA methylation alterations by CUR and its potential role in GI cancer prevention and treatment.

Long non-coding RNA (lncRNA) is a kind of biomolecule that can regulate important life activities such as cell proliferation, apoptosis, differentiation, aging, and body development. It has been found that lncRNAs are closely related to various diseases. In cardiovascular diseases, lncRNAs affect the expression level of related genes in atherosclerotic plaques, which are closely related to endothelial dysfunction, smooth muscle cell proliferation, macrophage dysfunction, abnormal lipid metabolism, and cellular autophagy, thus participating in regulating the occurrence and development of AS. In view of this, investigating the role of lncRNAs in regulating cardiac gene networks on cardiovascular system diseases has attracted much clinical attention and may be a novel target for AS therapy. This paper focuses on lncRNAs related to AS, explores the relationship between lncRNAs and AS, suggests the role of lncRNAs in the prevention and treatment of AS, and expects the application of more lncRNAs as the marker in the clinical diagnosis and treatment of AS.
