Local IGF-1 isoform protects cardiomyocytes from hypertrophic and oxidative stresses via SirT1 activity
Figure 8.mIGF-1 prevents Ang II- and PQ-dependent cell death in HL-1 cardiomyocytes and in mouse neonatal primary cardiomyocytes. (A, B) HL-1 cardiomyocytes were transfected or treated as in Legend of Figure 2A. (C, D) Neonatal primary cardiomyocytes from wild type or mIGF-1 Tg mice were treated as in Legend of Figure 2B. (A-D) Cell viability was monitored with propidium iodide (PI) by flow cytometry and values were normalized to protein content. Results are means ± SE of 3 independent experiments (*,**,***p versus unstimulated control cells or untreated wild type cardiomyocytes).
