Extinction of Oct-3/4 gene expression in embryonal carcinoma [times] fibroblast somatic cell hybrids is accompanied by changes in the methylation status, chromatin structure, and transcriptional activity of the Oct-3/4 upstream region
Abstract
The OCT-3/4 gene provides an excellent model system with which to study the extinction phenomenon in somatic cell hybrids. The molecular mechanism that underlies the extinction of a tissue-specific transcription factor in somatic cell hybrides is evaluated and compared with its down-regulation in retinoic acid treated embryonal carcinoma cells. This study draws a connection between the shutdown of OCT-3/4 expression in retinoic acid (RA)-differentiated embryonal carcinoma (EC) cells and its extinction in hybrid cells. This repression of OCT-3/4 expression is achieved through changes in the methylation status, chromatin structure, and transcriptional activity of the OCT-3/4 upstream regulatory region. 59 refs.
