Figure 4. Overexpression of CARP inhibits the activation of MEK/ERK signaling by hypertrophic stimuli.
(A) Western blotting of heart protein extracts to examine the levels of various phosphorylated and total kinases in WT and CARP Tg mice following TAC or a sham operation. A representative Western blot (from one of three independent experiments) is shown. (B) Western blotting of protein extracts to detect various phosphorylated and total kinase levels in parental and CARP-overexpressing cardiomyocytes subjected to phenylephrine treatment or not. A representative Western blot (from one of three independent experiments) is shown. (C) Quantification of the expression of the p-MEK1/2 and p-ERK1/2 proteins shown in (B) at 30 min after commencement of PE treatment.
