BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are extensively used pharmaceuticals and tons of kilos are produced annually. Ibuprofen is one of the core medicines of non-steroidal anti-inflammatory drug and is primarily used for reduced pain, fever and tissue inflammation. It is also available for the treatment of osteoarthritis, rheumatoid arthritis, tendonitis, etc. It is still one of the most prescribed non-steroidal anti-inflammatory drugs in contemporary times. Although ibuprofen is a drug that has been used for years, it is also known to have various serious toxic effects. OBJECTIVE: In this review, we aimed to clarify toxic and genotoxic effects of Ibuprofen by analyzing major journal indexes. METHODS: The search was concentrated on the Web of Science, PubMed, Science Direct, Scopus, EBSCO Host, and Google Scholar databases, including the keyword combinations "genotoxicity", "toxicity", "Ibuprofen". RESULTS: In the search procedure, a total number of 11738 studies about the topic were reviewed. Consequently, 42 studies were classified as appropriate according to the inclusion criteria and were therefore included in the review. The results presented and discussed in this review indicate that Ibuprofen might represent a toxic, genotoxic and teratogenic risk for non-target, freshwater invertebrates, vertebrates and toxic for human especially in overdose or misuse situation. CONCLUSION: Ibuprofen generally was found to be toxic, mutagenic, teratogenic and genotoxic agent in various organisms. In human cases mostly overdose or misuse was found to be toxic. However acute toxicity was also reported in some human clinical studies. More detailed genotoxicity, teratogenicity and especially carcinogenic potential should be investigated to reach full decision of its safety.

INTRODUCTION: Postnatal cardiomyocytes respond to stress signals by hypertrophic growth and fetal gene reprogramming, which involves epigenetic remodeling mediated by histone methyltransferase polycomb repressive complex 2 (PRC2) and histone deacetylases (HDACs). However, it remains unclear to what extent these histone modifiers contribute to the development of cardiomyocyte hypertrophy. METHODS: Neonatal rat ventricular myocytes (NRVMs) were stimulated by phenylephrine (PE; 50μM) to induce hypertrophy in the presence or absence of the PRC2 inhibitor GSK126 or the HDACs inhibitor Trichostatin A (TSA). Histone methylation and acetylation were measured by Western blot. Cell size was determined by wheat germ agglutinin (WGA) staining. Cardiac hypertrophy markers were quantified by quantitative reverse transcription polymerase chain reaction (qRT-PCR). RESULTS: PE treatment induced the expression of cardiac hypertrophy markers, including natriuretic peptide A (Nppa), natriuretic peptide B (Nppb), and myosin heavy chain 7 (Myh7), in a time-dependent manner in NRVMs. Histone modifications, including H3K27me3, H3K9ac, and H3K27ac, were dynamically altered after PE treatment. Treatment with TSA and GSK126 dose-dependently repressed histone acetylation and methylation, respectively. While TSA reversed the PE-induced cell size enlargement in a wide range of concentrations, cardiomyocyte hypertrophy was only inhibited by GSK126 at a higher dose (1μM). Consistently, TSA dose-dependently suppressed the induction of Nppa, Nppb, and Myh7/Myh6 ratio, while these indexes were only inhibited by GSK126 at 1μM. However, TSA, but not GSK126, caused pro-hypertrophic expression of pathological genes at the basal level. CONCLUSION: Our data demonstrate diversified effects of TSA and GSK126 on PE-induced cardiomyocyte hypertrophy, and shed light on epigenetic reprogramming in the pathogenesis of cardiac hypertrophy.

BACKGROUND: Worldwide, millions of people are affected by liver disorders and issues, and the successful treatment of patients seems challenging even after many treatment strategies. Presently, doctors are left with treatments like liver transplantation and resection. Researchers found it challenging to target the liver due to various drawbacks such as opsonization, mechanical entrapment, and RES uptake. METHODS: Literature (from the past ten years) on different research data on the treatment of liver diseases and study reports on the development of various nanocarriers targeting the liver have been collected using multiple search engines such as ScienceDirect, j-gate, google scholar, PubMed, sci-hub, etc. and data have been compiled accordingly. RESULTS: The basics of liver anatomy and various liver cells and pathophysiology of liver diseases, and liver targeting have been mentioned better to understand the further treatment of various liver disorders. Various Liver diseases such as hepatitis B, liver fibrosis, hepatocellular carcinoma, acute liver failure, and liver cirrhosis have been detailed in multiple research studies related to their treatment. Various strategies for active and passive liver targeting have also been overviewed. Several advanced reported nanocarriers (liposomes, polymeric micelles, nanoparticles, micro and nanoemulsions, and phytosomes) are mentioned and their potential in treating liver disorders has been summarized by compiling research reports related to these nanocarriers. CONCLUSION: The fabrication of nanomedicine incorporating nanocarriers and biomaterials for treating liver diseases is a big challenge. Understanding various aspects of liver anatomy and liver cells is the prime requirement while designing successful liver-targeted nano/microcarriers. Also, the choice of advanced or modified polymeric material in liver targeting is very crucial for their specific liver cell targeting, for their biocompatibility and biodegradability point of view.

Non-alcoholic fatty liver disease [NAFLD] is a common metabolic disorder associated with obesity, diabetes mellitus, dyslipidemia and cardiovascular disease. A "multiple hit" model has been a widely accepted explanation for the disease's complicated pathogenesis. Despite advances in our knowledge of the processes underlying NAFLD, there is no conventional pharmaceutical therapy. The only currently approved option is to make lifestyle modifications, such as dietary and physical activity changes. The use of medicinal plants in the treatment of NAFLD has gained interest. Thus, we review the current knowledge about these agents based on clinical and preclinical studies. Moreover, the association between NAFLD and colorectal cancer [CRC], one of the most common and lethal malignancies, has recently emerged as a new study area. We overview the shared dysregulated pathways and the potential therapeutic effect of herbal medicines for CRC prevention in patients with NAFLD.
