Epigenetic regulation of pluripotency inducer genes NANOG and SOX2 in human prostate cancer.

| Abstract |
The cells of multicellular organisms are genetically homogeneous but heterogenous in structure and function by virtue of differential gene expression. During embryonic development, differential gene expression by modification of chromatin (DNA and histone complex) regulates the developmental proceedings before and after the germ layers are formed. Post-replicative DNA modification, where the fifth carbon atom of the cytosine gets methylated (hereafter, DNA methylation), does not incorporate mutations within the DNA. In the past few years, a boom has been observed in the field of research related to various epigenetic regulation models, which includes DNA methylation, post-translational modification of histone tails, control of chromatin structure by non-coding RNAs, and remodeling of nucleosome. Epigenetic effects like DNA methylation or histone modification play a cardinal role in development but also be able to arise stochastically, as observed during aging, in tumor development and cancer progression. Over the past few decades, researchers allured toward the involvement of pluripotency inducer genes in cancer progression and apparent for prostate cancer (PCa); also, PCa is the most diagnosed tumor worldwide and comes to the second position in causing mortality in men. The anomalous articulation of pluripotency-inducing transcription factor; SRY-related HMG box-containing transcription factor-2 (SOX2), Octamer-binding transcription factor 4 (OCT4) or POU domain, class 5, transcription factor 1 (POU5F1), and NANOG have been reported in different cancers which includes breast cancer, tongue cancer, and lung cancer, etc. Although there is a variety in gene expression signatures demonstrated by cancer cells, the epigenetic mode of regulation at the pluripotency-associated genes in PCa has been recently explored. This chapter focuses on the epigenetic control of NANOG and SOX2 genes in human PCa and the precise role thereof executed by the two transcription factors.
