摘要:

目的 探究祛湿活血方对游离脂肪酸(FFA)诱导的HepG2细胞的作用及机制。 方法 采用体外细胞实验,利用CCK8法测定不同浓度祛湿活血方对HepG2细胞活性的影响以选定适宜浓度进行后续实验。随后使用250 μmol/L棕榈酸钠溶液联合500 μmol/L油酸钠的游离脂肪酸处理24 h诱导建立脂肪肝细胞模型,并给予不同浓度祛湿活血方含药血清及AMPK抑制剂对HepG2细胞进行24 h干预。通过油红O染色法和脂质荧光染色法观察细胞内脂滴积聚情况,采用GPO-PAP酶法检测细胞内总胆固醇(TC)和甘油三酯(TG)含量变化,TBA法检测和羟胺法分别检测丙二醛(MDA)和超氧化物歧化酶(SOD)的含量,ELISA检测肿瘤坏死因子-α(TNF-α)和白细胞介素1β(IL-1β)的含量,进一步运用qRT-PCR、Western blot和免疫荧光染色技术检测细胞内脂质代谢相关基因及蛋白的表达。 结果 祛湿活血方可显著改善FFA诱导的HepG2细胞脂质沉积,氧化应激及炎症反应,显著降低细胞中TC、TG、MDA、TNF-α、IL-1β的含量和提高SOD活性(P < 0.01),提高AMPK,降低SREBP1c、FASN、ACC1和SCD1的mRNA表达水平(P < 0.05),以及增加p-AMPK/AMPK,降低SREBP1c、FASN、ACC1和SCD1的蛋白表达(P<0.05)。 结论 祛湿活血方能够显著改善MASLD细胞模型的脂质代谢,并减轻氧化应激及炎症反应,其机制可能与激活AMPK/SREBP1c信号通路有关。

Abstract:

Objective To investigate the effect of Qushi Huoxue decoction (QSHXF) on free fatty acid (FFA)-induced HepG2 cells and its underlying mechanism. Methods In vitro cell experiments were conducted. First, the CCK-8 assay was used to determine the effects of different concentrations of QSHXF on HepG2 cells viability to select appropriate concentrations for subsequent experiments. A fatty liver cell model was then established by treating HepG2 cells with a mixture of 250 μmol/L sodium palmitate and 500 μmol/L sodium oleate for 24 h, followed by intervention with different concentrations of QSHXF-containing serum and AMPK inhibitor for another 24 h. Intracellular lipid droplet accumulation was observed using Oil Red O staining and lipid fluorescence staining. The levels of total cholesterol (TC) and triglycerides (TG) were measured using the GPO-PAP enzymatic method. The TBA method and hydroxylamine method were used to detect malondialdehyde (MDA) and superoxide dismutase (SOD), respectively, while ELISA was used to detect tumor necrosis factor-α (TNF-α) and interleukin 1β (IL-1β). Furthermore, qRT-PCR, Western blot, and immunofluorescence staining were performed to detect the expression of lipid metabolism-related genes and proteins. Results QSHXF significantly improved the lipid deposition, oxidative stress and inflammatory response of FFA-induced HepG2 cells, markedly reduce the content of TC, TG, MDA, TNF-α and IL-1β in cells and increase the activity of SOD (P < 0.01). Meanwhile, it increased the mRNA expression of AMPK and the protein ratio of p-AMPK/AMPK, while decreasing the mRNA and protein levels of SREBP1c, FASN, ACC1, and SCD1 (all P < 0.05). Conclusion QSHXF significantly improved lipid metabolism and alleviated oxidative stress and inflammation in the MASLD cell model, and its mechanism may be associated with the activation of the AMPK/SREBP1c signaling pathway.
