During cardiac hypertrophy, SGK1 also fosters the cytoplasmic localization of cyclin‐dependent kinase inhibitor 1B (p27), a protein which suppresses cardiac hypertrophy.[29, 40] Taken together, these findings suggest that SGK1 is a key factor in the progress of cardiac hypertrophy and thus a promising therapeutic target. Here, CDKN1B is linked to cardiac hypertrophy.
