Effects of DR-Ab on Ang II-induced H9c2 cardiomyocyte hypertrophy. DR-Ab (2 μM) was given 30 min before treatment with Ang II (100 nM) for 48 h. (a, b) Representative immunofluorescence staining (a) and group data (b) showing that DR-Ab reversed enlarged cell size caused by Ang II. Red: α-actinin. Blue: DAPI. Scale bar, 25 μm. n = 6. (c) qRT-PCR analysis showing the mRNA levels of ANP, BNP, and β-MHC. n = 4. (d–g) DR-Ab reversed Ang II-induced loss of plasma membrane NKA α1 (e, f), increase of endosome NKA α1 (g), and downregulation of NKA activity (d). n = 4~6. Scale bar, 30 μm. Blue: DAPI. Green: NKA α1 staining. ∗p < 0.05 versus control group, †p < 0.05 versus Ang II alone group.
