This implies that the interaction between the two vitamins is necessary to achieve meaningful photoprotection by dietary means
(Left) In liver cells, GLP-1 can mediate cholesterol efflux by acting directly on LXR, or by inducing an increase in ATP-binding cassette transporter A1 (ABCA1) mRNA through Ca2+/calmodulin (CaM)-dependent protein kinase kinase/CAM-dependent protein kinase IV/Prolactin regulatory element binding (CaMKK/CaMKIV/PREB), increasing apolipoprotein AI (apo AI) mRNA and promoter expression, and increasing apo AI secretion, thereby mediating intracellular cholesterol efflux
