AMP-Activated Protein Kinase Activation during Cardioplegia-Induced Hypoxia/Reoxygenation Injury Attenuates Cardiomyocytic Apoptosis via Reduction of Endoplasmic Reticulum Stress

Figure 3

Reverse transcription PCR analysis showed up-regulation of ATF6, VEGF, Grp78, and spliced XBP-1 mRNAs in HL-1 cardiomyocytes from different groups. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) served as the loading control. The PCR products of GAPDH, ATF6, VEGF, Grp78, and spliced XBP-1 were designed to be around 200 bp. Quantitative real-time PCR showed an elevated ratio of these mRNAs in various groups. (Results are representative of at least 3 separate experiments. * 𝑃 < . 0 5 compared with Group 1; H: hypoxia; R: reoxygenation; Met: metformin.)
