Osteoporosis is considered as one of the most common diseases that women face after their menopause and is caused by both genetic and environmental factors.  Dipeptidyl peptidase 4 (DPP-4) gene is one of the important genetic factors contributing in osteoporosis which has a direct and very important relationship with fasting. Fasting is one of the alternatives proved to reduce the DPP-4 level a...

Background: Recently, it has been revealed that tyrosine kinase inhibitors (TKIs) act through inducing both oxidative and endoplasmic reticulum (ER) stress in chronic myeloid leukemia cells. However, ER stress signaling triggers both apoptotic and survival processes within cells. Nevertheless, mechanisms by which TKIs avoid the pro-survival effects are not clear. The aim of this study was to ev...

Resistance develops due to mutations in the reverse transcriptase gene of HIV-1 genome that does not respond towards the presence of effective drugs. Emergence of HIV-1 variants in the presence of effective drugs is a common occurrence. Drug resistance mutation means “the development of resistance mutations in the drug targeted HIV-1 genes” which causes the viruses to overcome the drug pressure...

Dynamic histone acetylation, catalyzed by lysine acetyltransferases and HDACs, is critical to IEG expression. Expression of IEGs, such as FOSL1, is induced by several signal transduction pathways resulting in activation of the protein kinase MSK and phosphorylation of histone H3 at serine 10 of nucleosomes (the nucleosome response) at the upstream promoter and regulatory region of target genes....

Ewing sarcoma is driven by characteristic chromosomal translocations between the EWSR1 gene with genes encoding ETS family transcription factors (EWS-ETS), most commonly FLI1. However, direct pharmacological inhibition of transcription factors like EWS-FLI1 remains largely unsuccessful. Active gene transcription requires orchestrated actions of many epigenetic regulators, such as the bromodomai...

Phosphodiesterase 4 (PDE4) has been established as a promising target in asthma andchronic obstructive pulmonary disease. PDE4B subtype selective inhibitors are known toreduce the dose limiting adverse effect associated with non-selective PDE4B inhibitors. Thismakes the development of PDE4B subtype selective inhibitors a desirable research goal. Toachieve this goal, ligand based pharmacophore m...

OBJECTIVE Lung cancer is the leading cause of cancer-related mortality. Over 80% of all lung cancer cases are non-small-cell lung cancer (NSCLC) and approximately 5% of NSCLC patients are positive for anaplastic lymphoma kinase (ALK) gene rearrangement or fusion with echinoderm microtubule-associated protein-like 4 (EML4). NSCLC patients with positive ALK-EML4 gene fusion are highly sensitive t...

OBJECTIVE Generalized DNA hypomethylation contributes to altered T cell function and gene expression in systemic lupus erythematosus (SLE). Some of the overexpressed genes participate in the disease process, but the full repertoire of genes affected is unknown. Methylation-sensitive T cell genes were identified by treating T cells with the DNA methyltransferase inhibitor 5-azacytidine and compa...
