Abstract:
This study was purposed to investigate the effect of RUNX1 on transcription activity of WNT5A promoter in mouse bone marrow derived mesenchymal stem cells (MSC), and to explore the mechanism by which bone marrow environments regulate MSC. RT-PCR was used to detect the expression of RUNX1 in MSC isolated from mouse bone marrow and cultured in vitro; the chromatin immunoprecipitation (ChIP) was used to investigate the direct in vivo interaction between the RUNX1 and WNT5A promoter; retrovirus system was utilized to introduce the RUNX1 gene into MSC to detect the regulation of RUNX1 on the transcription activity of WNT5A promoter. The results showed that mouse bone marrow derived MSC was positive for Oil Red O, van Kossa and toluidine blue staining respectively and RUNX1 expressed in MSC. WNT5A promoter could be bound by RUNX1, and the expression level of WNT5A was enhanced with the increase of RUNX1. It is concluded that RUNX1 expresses in mouse bone marrow derived MSC, WNT5A is a direct target gene of RUNX1 and its transcriptional activity is regulated by RUNX1.
