A comprehensive overview of CRISPR/Cas 9 technology and application thereof in drug discovery.

Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-Cas technology possesses revolutionary potential to positively affect various domains of drug discovery. It has initiated a rise in the area of genetic engineering and its advantages range from classical science to translational medicine. These genome editing systems have given a new dimension to our capabilities to alter, detect and annotate specified gene sequences.

Hypertension is prevalent in non-alcoholic fatty liver disease and increases all-cause and cardiovascular mortality.

Background And Aims: Hypertension (HTN) is a common comorbidity in non-alcoholic fatty liver disease (NAFLD) affecting up to 40% of individuals. However, the impact of HTN and its control on outcomes in NAFLD remains unclear. Therefore, we aimed to examine the impact of HTN on survival outcomes in a longitudinal cohort of NAFLD patients.

Erythroid lineage-specific lentiviral RNAi vectors suitable for molecular functional studies and therapeutic applications.

Numerous genes exert multifaceted roles in hematopoiesis. Therefore, we generated novel lineage-specific RNA interference (RNAi) lentiviral vectors, H23B-Ery-Lin-shRNA and H234B-Ery-Lin-shRNA, to probe the functions of these genes in erythroid cells without affecting other hematopoietic lineages. The lineage specificity of these vectors was confirmed by transducing multiple hematopoietic cells to express a fluorescent protein.

Ameliorative effect of cerium oxide nanoparticles against Freund's complete adjuvant-induced arthritis.

To assess the mechanistic effects of cerium oxide nanoparticles (CONPs) on Freund's complete adjuvant (FCA)-induced rheumatoid arthritis in rats. CONPs were characterized and evaluated (RAW 264.7 macrophages) and (FCA-induced rheumatoid arthritis model).

Gene therapy: Comprehensive overview and therapeutic applications.

Gene therapy is the product of man's quest to eliminate diseases. Gene therapy has three facets namely, gene silencing using siRNA, shRNA and miRNA, gene replacement where the desired gene in the form of plasmids and viral vectors, are directly administered and finally gene editing based therapy where mutations are modified using specific nucleases such as zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs) and clustered regulatory interspaced short tandem repeats (CRISPR)/CRISPR-associated protein (Cas)-associated nucleases. Transfer of gene is either through transformation where under specific conditions the gene is directly taken up by the bacterial cells, transduction where a bacteriophage is used to transfer the genetic material and lastly transfection that involves forceful delivery of gene using either viral or non-viral vectors.

It's all about the spaces between cells: role of extracellular matrix in liver fibrosis.

Liver fibrosis is one of the leading complications of a variety of chronic liver disorders, including the nonalcoholic fatty liver disease, nonalcoholic steatohepatitis, liver cirrhosis and liver failure. The progression of liver fibrosis is driven by chronic inflammation, which activates the secretory fibroblasts to the myofibroblast phenotype. These specialized liver cells are called as hepatic stellate cells (HSCs).

Withaferin A reverses bile duct ligation-induced liver fibrosis by modulating extracellular matrix deposition: Role of LOXL2/Snail1, vimentin, and NFκB signaling.

Herein, we studied the effect of Withaferin A (WFA) in reversing bile duct ligation (BDL)-induced liver fibrosis. BDL was performed on C57BL/6J mice and 2 days later, WFA (1 and 3 mg/kg) was administered for 12 days. Estimation of liver enzymes and assays for lipid peroxidation, reduced glutathione, and nitrite levels were performed.

Superoxide dismutase mimetic nanoceria restrains cerulein induced acute pancreatitis.

The present study was carried out to assess the effect of nanoceria (NC) on pancreatic inflammation caused by cerulein. NC was characterized and studies were carried out in murine macrophages. The effects were tested on cerulein-induced pancreatitis.

Yttrium oxide nanoparticles reduce the severity of acute pancreatitis caused by cerulein hyperstimulation.

Oxidative stress plays a major role in acute pancreatitis (AP), leading to massive macrophage infiltration. Nanoyttria (NY) possesses potent free radical scavenging activity. As reactive oxygen species and inflammation play major role in AP, we hypothesized that NY may alleviate cerulein induced AP.

Isoproterenol-induced cardiac ischemia and fibrosis: Plant-based approaches for intervention.

Heart is the most active and incumbent organ of the body, which maintains blood flow, but due to various pathological reasons, several acute and chronic cardiac complications arise out of which myocardial infarction is one of the teething problems. Isoproterenol (ISP)-induced myocardial ischemia is a classical model to screen the cardioprotective effects of various pharmacological interventions. Phytochemicals present a novel option for treating various human maladies including those of the heart.
