Figure Lengend Snippet: Figure 2. Reduction of TGFβ1 expression by downregulation of RyR2in cardiomyocytes under mechani- cal stretch. A: Measurement of RyR2 mRNA level in cultured cardiomyocytes by Real-Time PCR. B: Expres- sion of RyR2 protein level in cardiomyocytes with Western Blotting. C: TGFβ1 in supernates of cultured cardiomyocytes was detected with ELISA analysis. D: Expression of TGFβ1 protein level in cardiomyocytes with Western Blotting. E: Measurement of tgfb1 mRNA level in cultured cardiomyocytes using Real-Time PCR. Values are expressed as mean ± SEM obtained from 3 independent experiments. shRyR2 indicates RyR2 knockdown lentiviral particle-infected cardiomyocytes; MS, cardiomyocytes under mechanical stretch; MS + ryr2 KD, RyR2 knockdown cardiomyocytes under mechanical stretch. *P < 0.05 versus control.

Article Snippet: ELISA assay: Supernates of cultured cardiomyocytes were collected and examined by Rat Transforming Growth Factor β1 ELISA Kit (CUSABIO BIOTECH, China) following the manufacturer’s instructions.
