Transcription profiling by array of HC11 mammary epithelial cell strains stably expressing different variants of the transcriptional regulator megakaryoblastic leukemia-1 (Mkl1)

We have previously shown that HC11 mammary epithelial cells react strongly to the overexpression of megakaryoblastic leukemia-1 (Mkl1) with induction of tenascin-C expression. The present study was designed to find genes co-regulated with tenascin-C by Mkl1 in a SAP domain-dependent manner and without the involvement of serum response factor (SRF). For this purpose, we compared the transcriptomes of three stable HC11 cell strains that either overexpress full length Mkl1-RFP (HC11-FL), Mkl1-RFP with a mutated SRF-interaction site (HC11-mutB1) or Mkl1-RFP with a deletion of the SAP domain (HC11-SAP).
