摘 要 目的 基于微RNA(miRNA)-204/NUAK家族SNF1样激酶1(NUAK1)/Hippo信号轴研究红花总黄酮(TFCTL)抑制肝星
状细胞(HSC)活化的作用,为进一步阐明 TFCTL 抗肝纤维化的作用机制提供参考。方法 将 HSC-T6 细胞分为对照组、模型组、
TFCTL低浓度组(20 μg/mL)、TFCTL中浓度组(40 μg/mL)、TFCTL高浓度组(60 μg/mL)。除对照组外,其余各组均加入5 ng/mL
的转化生长因子β诱导HSC活化,然后加入相应药液/培养基培养24 h。培养结束后,检测细胞凋亡情况以及细胞中α-平滑肌肌
动蛋白(α-SMA)、Ⅰ型胶原蛋白(Collagen Ⅰ)和Hippo/Yes相关蛋白(YAP)通路相关蛋白[YAP、大肿瘤抑制激酶1(LATS1)、哺乳
动物STE20样激酶1(MST1)]表达。另采用细胞转染法从基因、蛋白层面分别考察TFCTL对miRNA-204/NUAK1/Hippo信号轴活
性的影响。结果 经TFCTL干预后,HSC-T6细胞凋亡率和细胞中MST1(TFCTL高浓度组除外)、LATS1蛋白表达水平均显著升
高(P<0.05),细胞中α-SMA、Collagen Ⅰ、YAP(TFCTL中浓度组除外)蛋白表达水平均显著降低(P<0.05)。进一步的细胞转染
实验结果显示,转染miRNA-204模拟物后,HSC-T6细胞中α-SMA、Collagen Ⅰ、NUAK1、YAP mRNA及其蛋白表达水平均显著降
低(P<0.05),LATS1 mRNA及其蛋白表达水平、MST1 mRNA表达水平均显著升高(P<0.05),且转染miRNA-204抑制剂后的结
果与之相反(MST1 mRNA除外)。结论 TFCTL可通过上调miRNA-204表达,下调NUAK1表达,抑制Hippo/YAP通路活性,从而
抑制HSC活化并促进其凋亡,进而发挥抗肝纤维化作用。

ABSTRACT OBJECTIVE To investigate the effects of total flavonoids from Carthamus tinctorius L. (TFCTL) on hepatic
stellate cell (HSC) activation based on the microRNA (miRNA)-204/NUAK family SNF1-like kinase 1 (NUAK1)/Hippo signaling
axis, thereby elucidating the potential mechanism underlying their antifibrotic effects. METHODS The HSC-T6 cells were divided
into control group, model group, TFCTL low-concentration group (20 μg/mL), TFCTL medium-concentration group (40 μg/mL),
and TFCTL high-concentration group (60 μg/mL). Except for control group, the remaining groups were treated with 5 ng/mL of
transforming growth factor- β to induce the activation of hepatic stellate cells, followed by the addition of corresponding drug
solutions/culture medium and incubation for 24 hours. Cell apoptosis was assessed, the expression levels of α-smooth muscle actin
(α-SMA), type Ⅰ collagen (Collagen Ⅰ) and proteins associated with the Hippo/Yes-associated protein (YAP) pathway [YAP,
large tumor suppressor kinase 1 (LATS1), and mammalian STE20-like kinase 1 (MST1)] were detected. Additionally, cell
transfection was used to investigate the activity of the miRNA-
