Abstract

Members of the SOX (SRY box) family proteins play critical roles in multiple aspects of development. SRY, as a founder member of SOX family, has been long believed to be involved in the development of sexual gonads by triggering signaling cascades which lead to the formation of testis or ovary from bipotential gonads. However, less is known about other potential regulatory roles of SRY in the development and differentiation. In order to gain further insight into the possible roles of SRY during development, we looked into possible SRY-regulated genes and their levels of expression in a human embryonic carcinoma cell line, named NTera2, before and after induction of differentiation. For this respect, SRY incorporation on the regulatory regions of two groups of genes including OCT4, NANOG, and SOX2 as pluripotency marker genes, and NESTIN and PAX6 as differentiation marker genes were evaluated quantitatively. Chromatin immunoprecipitation using SRY antibody was performed on chromatin extract of a human embryonic carcinoma cell line, NT2/NTERA-2, before and after onset of differentiation. The results showed that incorporation of SRY in both groups of genes was increased after induction of differentiation. Besides, lower expression of OCT4, SOX2, and NANOG and higher expression of PAX6 and NESTIN genes in differentiated cells suggest that SRY may act as a transcription repressor for pluripotency-associated genes and as a transcription activator for differentiation-related genes.
