The objective of this work was to investigate the effect of berberine (BBR) on the Cell viability, lipid accumulation, apoptosis, cytochrome c, caspase-9 and caspase-3 in lipid accumulation-hepatocytes induced by sodium palmitate in vitro. The lipid accumulation-hepatocytes (induced by 0.5 mM sodium palmitate for 24 h) were treated with 5 μM berberine for 12 h. Then, the Cell viability, intracellular triglyceride (TG) content, lipid peroxide (LPO), malonaldehyde (MDA) content, cytochrome c, caspase-9, caspase-3 and apoptosis were detected. Sodium palmitate decreased Cell viability and increased intracellular TG content, lipid droplet accumulation, LPO and MDA concentrations, caused caspase-3 and caspase-9 activation, then led to apoptosis accompanied by cytochrome c release from mitochondria into the cytoplasm. Beberine could improve intracellular lipid droplet accumulation and oxidative stress, while reduce apoptosis induced by sodium palmitate.
本研究旨在探讨小檗碱（BBR）对体外棕榈酸钠诱导的脂肪堆积肝细胞中细胞活力、脂滴积累、细胞凋亡、细胞色素 c、半胱氨酸天冬氨酸蛋白酶-9（caspase-9）和半胱氨酸天冬氨酸蛋白酶-3（caspase-3）的影响。用 0.5mM 棕榈酸钠处理细胞 24h 诱导脂肪堆积肝细胞，然后用 5μM 小檗碱处理细胞 12h。检测细胞活力、细胞内三酰甘油（TG）含量、脂质过氧化物（LPO）、丙二醛（MDA）含量、细胞色素 c、caspase-9、caspase-3 和细胞凋亡。结果表明，棕榈酸钠降低细胞活力，增加细胞内 TG 含量、脂滴积累、LPO 和 MDA 浓度，激活 caspase-3 和 caspase-9，导致细胞色素 c 从线粒体释放到细胞质，引发细胞凋亡。小檗碱可改善细胞内脂滴堆积和氧化应激，同时减少由棕榈酸钠诱导的细胞凋亡。
