HIF-1α positively regulates GFAT2 in cardiomyocyte hypertrophy
(A) Representative immunoblots of HIF-1α, GFAT2, phospho-Akt(S473), Akt, and GAPDH in NRVMs treated with indicated siRNA in the presence or absence of ISO (1 μM, 12 h) (n = 5).
(B–D) Quantitative analysis of protein HIF-1α, GFAT2, and phospho-Akt in NRVMs treated with indicated siRNA in the presence or absence of ISO (1 μM, 12 h) (n = 5).
(E) Expression of GFAT2 and 18S mRNA in NRVMs treated with indicated siRNA in the presence or absence of ISO (1 μM, 12 h) (n = 5).
(F) Cell surface area of NRVMs treated with indicated siRNA in the presence or absence of ISO (1 μM, 12 h) (n = 150 cells in each group). Scale bar, 50 μm. ∗p < 0.05, ∗∗p < 0.01: post hoc Tukey's comparison test.
