Figure 1. The expression of PGC-1α was upregulated during cardiomyocyte differentiation; ZLN005 increased PGC-1α mRNA and protein level in hESC-CMs. (A) The relative mRNA and (B) protein expression of PGC-α during cardiomyocyte differentiation (mRNA, n=7; protein, n=5). (C) Schematic representation of the experimental schedule including hESC culture, cardiomyocyte differentiation, culture and treatment. (D) Effect of ZLN005 on mRNA levels (n=6). (E) Effect of ZLN005 on PGC-α protein expression (n=12).
