摘 要 目的 探究骨碎补总黄酮(TFRD)调控Notch1/发状分裂相关增强子1(Hes1)信号轴对脂多糖(LPS)诱导的软骨细胞自噬
及凋亡的影响。方法 采用5 μg/mL LPS处理人软骨细胞系C28/I2细胞构建体外炎症损伤模型,将细胞分为正常对照组、模型组、
TFRD 组(200 μg/mL)、TFRD+过氧化物氧化还原酶 1(Prdx1)小干扰 RNA(si-Prdx1)组和 TFRD+si-Prdx1 阴性对照(si-NC)组,每
组设6个复孔。细胞以si-Prdx1或si-NC转染24 h、TFRD预处理2 h,再以LPS处理,总计培养48 h。检测细胞凋亡率、凋亡细胞占
比、单丹磺酰尸胺(MDC)荧光强度和基质金属蛋白酶 13(MMP-13)、含Ⅰ型血小板结合蛋白基序的解聚蛋白样金属蛋白酶 5
(ADAMTS5)、软骨寡聚基质蛋白(COMP)含量以及X连锁凋亡抑制蛋白(XIAP)、多腺苷二磷酸核糖聚合1(PARP1)、Beclin-1、微
管相关蛋白 1 轻链 3Ⅱ/Ⅰ(LC3-Ⅱ/Ⅰ)、PTEN 诱导激酶 1(PINK1)、Notch1、Hes1、Prdx1 蛋白表达情况。结果 与模型组比较,
TFRD组细胞凋亡率、凋亡细胞占比和MMP-13、ADAMTS5含量以及PARP1蛋白表达水平均显著降低,MDC荧光强度、COMP含
量和 XIAP、Beclin-1、LC3-Ⅱ/Ⅰ、PINK1、Notch1、Hes1、Prdx1 蛋白表达水平均升高(P<0.05)。与 TFRD+si-NC 组比较,TFRD+si-
Prdx1组细胞中除Notch1、Hes1以外上述指标的变化均被显著逆转(P<0.05)。结论 TFRD可能通过激活Notch1/Hes1信号轴上
调下游靶分子Prdx1的表达,进而抑制LPS诱导的软骨细胞凋亡、促进其保护性自噬,从而改善软骨代谢稳态。

ABSTRACT OBJECTIVE To investigate the effects of total flavonoids of Drynariae Rhizoma (TFRD) on autophagy and
apoptosis in LPS-induced chondrocytes via the regulation of the Notch1/hairy and enhancer of split 1 (Notch1/Hes1) signaling axis.
METHODS Human chondrocyte cell line C28/I2 cells were cultured with 5 μg/mL LPS to establish in vitro inflammatory injury
model. The cells were separated into normal control group, model group, TFRD group (200 μg/mL), TFRD+peroxiredoxin 1
(Prdx1) small interfering RNA (si-Prdx1) group and TFRD+si-Prdx1 negative control (si-NC) group, with 6 replicate wells in
each group. Cells were transfected with si-Prdx1 or si-NC for 24 hours, pretreated with TFRD for 2 hours, and then exposed to
LPS, with a total culture duration of 48 hours. Apoptotic rate, the proportion of apoptotic cells, monodansylcadaverine (MDC)
fluorescence intensity, as well as the contents of matrix metalloproteinase-13 (MMP-13), a disintegrin and metalloproteinase with
thrombospondin motifs 5 (ADAMTS5), and cartilage oligomeric matrix protein (COMP) were measured. Additionally, the protein
expression levels of X-linked inhibitor of apoptosis protein (XIAP), poly(ADP-ribose) polymerase 1 (PARP1), Beclin-1,
microtubule-associated protein 1 light chain 3 Ⅱ/Ⅰ (LC3-Ⅱ/Ⅰ), PTEN-induced putative kinase 1 (PINK1), Notch1, Hes1, and
Prdx1 were assessed. RESULTS Compared with model group, the apoptotic rate, the proportion of apoptotic cells, the contents of
MMP-13 and ADAMTS5 as well as protein expressions of
