RPS6KB1 and cardiac hypertrophy: Most studies have acknowledged that mTORC1 signaling is activated in the induction of cardiac hypertrophy by chronic infusion of ISO, probably due to the important regulatory role of mTORC1‐P70S6K in protein synthesis required for cardiac hypertrophy (Bi et al., 2022; Gao et al., 2020a, 2020b; Lin et al., 2022; Mao et al., 2020; Sun et al., 2021).
