UNLABELLED Epigenetic regulations of genes by reversible methylation of DNA (at the carbon-5 of cytosine) and numerous reversible modifications of histones play important roles in normal physiology and development, and epigenetic deregulations are associated with developmental disorders and various disease states, including cancer. Stem cells have the(More)
While studying on epigenetic regulatory mechanisms (DNA methylation at C-5 of -CpG- cytosine and demethylation of methylated DNA) of certain genes (FAS, CLU, E-cadh, CD44, and Cav-1) associated with prostate cancer development and its better management, we noticed that the used in vivo dose of 5-aza-2'-deoxycytidine (5.0 to 10.0 nM, sufficient to inhibit(More)
Integrin-associated signaling is a crucial signaling network in mammalian cells. Thousands of molecules are involved in this signaling network. For example, the RTK, Src-family kinase, Ras, Wnt-, Notch-, and Raft/caveolae-mediated signaling pathways are related to integrin signaling. Integrin signaling is also associated with direct involvement of lipid(More)
The dynamic nature of chromatin and its myriad modifications play a crucial role in gene regulation (expression and repression) during development, cellular survival, homeostasis, ageing, and apoptosis/death. Histone 3 lysine 4 methylation (H3K4 methylation) catalyzed by H3K4 specific histone methyltransferases is one of the more critical chromatin(More)
DNA methylation mediates gene silencing primarily by inducing repressive chromatin architecture via a common theme of interaction involving methyl-CpG binding (MBD) proteins, histone modifying enzymes and chromatin remodelling complexes. Hence, targeted inhibition of MBD protein function is now considered a potential therapeutic alternative for thwarting(More)
Caveolin-1 (CAV1) is an integral part of plasma membrane protein playing a vital role in breast cancer initiation and progression. CAV1 acts both as a tumor suppressor as well as an oncogene, and its activity is thus highly dependent on cellular environment. Keeping this fact in mind, the recent work is designed to reveal the role of CAV1 in inhibiting(More)
Reversible DNA methylation is a fundamental epigenetic manipulator of the genomic information in eukaryotes. DNA demethylation plays a very significant role during embryonic development and stands out for its contribution in molecular reconfiguration during cellular differentiation for determining stem cell fate. DNA demethylation arbitrated extensive(More)
The role and clinical implication of ZRF1 in breast cancer are poorly understood. So this study is aimed to explore the role of ZRF1 in breast cancer progression. With this context, we first assessed its expression pattern in FFPE primary and metastasis breast tissue samples as well as from publicly available databases. Moreover, we also explored the(More)
