Figure 3. DMH1-treated cells showed increased cardiomyocyte lineage commitment.

Figure 3

(Left) DMH1 induces significant upregulation of transcription factor for cardiomyocyte commitment (Nkx2.5) compared with DMSO control. DM also induces Nkx2.5 expression, but the induction is less robust than DMH1. Results are presented as the average of three independent experiments. Expression levels shown are normalized to Day 0 expression levels. Error bars denote the S.E.M. (standard error of the mean). P-value is calculated using two-tailed Student’s t-test. (Right) Western blot showing increased Myl7 expression (∼19 kDa), a structural protein specific to cardiomyocytes, in CGR8 cells 8 days after DM or DMH1 induction. No Myl7 expression was observed after DMSO treatment. Alpha-tubulin (∼50 kDa) is shown as loading control. The relative intensities of Myl7 bands are normalized to alpha-tubulin and are shown at the bottom.
