Ginsenoside Rg1 attenuates mechanical stress-induced cardiac injury via calcium sensing receptor-related pathway

The mechanism of cardioprotection by Ginsenoside Rg1 via downregulation of CaSR. AAC induces overload of [Ca2+]i through CaSR/IP3R pathway. The increased [Ca2+]i leads to activation of CaN signaling pathway, resulting in cardiac hypertrophy and fibrosis. Ginsenoside Rg1 inhibits cardiac hypertrophy and fibrosis through inhibiting [Ca2+]i and downregulation of CaSR, CaN and TGF-β1 signaling pathways.Image 1
