Modulatory effect of berberine on plasma lipoprotein (or lipid) profile: a review.

Berberine is a bioactive isoquinoline alkaloid compound extracted from various medicinal plants, such as Barberry. Berberine shows various pharmacological properties that are mainly attributed to its anti-inflammatory and antioxidant effects. A growing body of evidence has shown that berberine influences cholesterol metabolism, and consequently, may ameliorate dyslipidemias and atherosclerosis. Plasma high-density lipoprotein cholesterol (HDL-C) is known to have an independent negative association with incident cardiovascular disease (CVD). However, several outcomes trials and genetic studies have failed to meet expecting the beneficial effects of elevating plasma HDL-C concentrations. Hence, investigations are currently focused on enhancing the functionality of HDL particles, independent of their plasma concentrations. HDL particles show various qualities because of a heterogeneous composition. Consistent with complex metabolism and composition, various biological functions are found for HDL, such as anti-inflammatory, antioxidant, anti-apoptotic, and anti-thrombotic activities. Protective effects of berberine may impact the functionality of HDL; therefore, the present literature review was intended to determine whether berberine can amplify HDL function. It was concluded that berberine may regulate markers of HDL activity, such as apo-AI, cholesterol efflux, LCAT, PON1, and S1P activities and levels. Consequently, berberine may recuperate conditions with dysfunctional HDL and, therefore, have the potential to emerge as a therapeutic agent. However, further human trials of berberine are warranted to evaluate its impact on HDL function and cholesterol metabolism.
