1 Valosin-containing protein (VCP), a suppressor of cardiac hypertrophy via inhibiting mechanistic target of rapamycin (mTOR) signaling, was validated as a target of miR-339-5p. mir-339-5p mechanistic target of rapamycin kinase Rattus norvegicus
2 Valosin-containing protein (VCP), a suppressor of cardiac hypertrophy via inhibiting mechanistic target of rapamycin (mTOR) signaling, was validated as a target of miR-339-5p. mir-339-5p mechanistic target of rapamycin kinase Rattus norvegicus
3 MiR-339-5p suppressed VCP protein expression, leading to elevated phosphorylation of mTOR and ribosomal protein S6 kinase (S6K). mir-339-5p mechanistic target of rapamycin kinase Rattus norvegicus
4 VCP depletion activated the mTOR/S6K cascade and could compromise the anti-hypertrophic effects of miR-339-5p inhibitor. mir-339-5p mechanistic target of rapamycin kinase Rattus norvegicus
5 Additionally, the hypertrophic responses caused by miR-339-5p was alleviated in the presence of mTOR inhibitor rapamycin. mir-339-5p mechanistic target of rapamycin kinase Rattus norvegicus
6 In conclusion, our research revealed that miR-339-5p promoted ISO-induced cardiomyocyte hypertrophy by targeting VCP to activate the mTOR signaling, suggesting a promising therapeutic intervention by interfering miR-339-5p. mir-339-5p mechanistic target of rapamycin kinase Rattus norvegicus
