Embelin influences cholesterol metabolismEmbelin Elevates Endoplasmic Reticulum Calcium Levels and Blocks the Sterol Regulatory Element-Binding Protein 2 Mediated Proprotein Convertase Subtilisin/Kexin Type 9 Expression and Improves the Low-Density Lipoprotein Receptor Mediated Lipid Clearance on Hepatocytes.
Calcium's impact on cholesterol highlighted.
We examined the effects of embelin, a compound derived from the dried berries of Embelia ribes, on cholesterol levels by focusing on its relationship with calcium in liver cells. Our analysis showed that embelin treatment aids in regulating cholesterol metabolism by influencing key proteins associated with cholesterol clearance.
The study highlighted how embelin can elevate calcium levels within the endoplasmic reticulum (ER), which is essential for proper cellular function. By increasing calcium, we observed a decrease in the activity of a protein known as PCSK9, which typically hinders the liver's ability to remove low-density lipoprotein (LDL) cholesterol from circulation.
By regulating the levels of SREBP2, another protein linked to cholesterol control, embelin ultimately enhances the liver's capacity to clear LDL from the bloodstream. This mechanism reveals that calcium plays an important role, particularly in how embelin mediates cholesterol levels through its effects on proteins involved in cholesterol metabolism.
Overall, the findings suggest that embelin may offer a natural avenue for improving cholesterol management, particularly in the context of cardiovascular health.
