Application

Neferine has been used to study its effect in autophagy signalling.

Biochem/physiol Actions

Neferine is a bis-benzylisoquinoline alkaloid isolated from the green seed embryos Nelumbo Nucifera Gaertn (Lotus) that displays multiple pharmacological activities including anti-tumor, antidepressant-like and antiarrhythmic actions. Recent studies shown that neferine potently inhibits proliferation of human osteosarcoma cells while is low-toxic on non-neoplastic human osteoblast cells. Apparently in U2OS cells, neferine stabilizes p21 through the activation of p38 MAPK, which leads to G1 cell cycle arrest. Also, neferine inhibits Ang II-induced HUVSMC proliferation by upregulation of HO-1.

Autophagy is an intracellular catabolic pathway in which cellular constituents are engulfed by autophagosomes and degraded upon autophagosome fusion with lysosomes. Autophagy serves as a major cytoprotective process by maintaining cellular homeostasis and recycling cytoplasmic contents. However, emerging evidence suggests
