TRPC3 loss robustly aggravated the alcohol-induced hepatic steatosis and liver injury in mouse liver; this was associated with the suppression of Ca2+/calmodulin-dependent protein kinase kinase 2 (CAMKK2)/AMP-activated protein kinase (AMPK) and dysregulation of genes related to lipid metabolism. Here, TRPC3 is linked to Hepatic steatosis.
