We showed that SF-1 expression induces differentiation of mesenchymal stem cells into steroidogenic cells. In order to elucidate the mechanisms of epigenetic regulations in differentiation into steroidogenic cells including ovarian cells, we attempted a couple of experiments using the differentiated cell.(1) One is functional analysis of the nuclear complex components with SF-1.(2) The other is combined-analysis with ChIP-on-Chip and DNA microarray to identify novel SF-1 target genes.(1) Transcription factor C/EBPβwas identified as one of the nuclear complex components with SF-1. We found that C/EBPβcooperated with SF-1 to enhance the transcriptional activity of HSD3B2 gene expression, which codes for one of the enzymes for progesterone production.(2) We identified GSTA3, ALAS1 and FDXR as novel SF-1-target genes. Transcriptional activity of these genes were enhanced by SF-1 via epigenetic change. We also found these factors were involved in steroidogenesis. These results indicate that these factors are novel SF-1-target genes and participate in steroid hormone production.
