Objective: To observe the effect of serum containing Duhuo Jisheng Tang for rat knee osteoarthritis (KOA) on articular chondrocyte apoptosis
endoplasmic reticulum stress related proteins glucoseregulated protein 78(GRP78)
CCAAT/enhace-binding protein homologous protein(CHOP) and anti-aging proteins HIRA
ASF1a. Method: Hulth method was adopted to establish the rat KOA model. After successful modeling
enzyme digestion method was applied in primary culture of normal chondrocytes and KOA cartilage cells; Forty rats were divided into for groups: low
middle and high-dose groups(0.85
1.7
3.4g·kg-1) and positive control group (glucosamine sulfate
3 g·kg-1). After 14 days of intragastric administration
serum was collected. Cultured cells were divided into control group
model group
Duhuo Jisheng Tang-containing serum groups (high
middle and low-dose groups) and positive control group; cell counting kit-8(CCK-8)method was used to test the cell proliferation of each group; TUNEL method was used to measure the cell apoptosis of each group. The expressions of ASF1a
HIRA
GRP78 and CHOP in chondrocytes were detected by Western blot. Result: Compared with the control group
the inhibition rate of cell proliferation was significantly increased in the model group; compared with the model group
the proliferation inhibition rates of chondrocytes in the low
middle
high-dose Duhuo Jisheng Tang groups and the positive control group were significantly decreased (P<0.05); compared with the control group
the number of apoptotic cells in the model group was significantly increased; compared with the model group
the apoptotic rates of chondrocytes in the low
middle
high-dose Duhuo Jisheng Tang groups and the positive control group were significantly decreased (P<0.05). Compared with the control group
the expressions of ASF1a
HIRA
GRP78 and CHOP in the model group were significantly higher than those in the control group; and compared with the model group
the expressions of ASF1a
HIRA
GRP78 and CHOP in chondrocytes of the low
middle
high-dose Duhuo Jisheng Tang groups and the positive control group were significantly decreased (P<0.05). Conclusion: The serum containing Duhuo Jisheng Tang could reduce the expressions of GRP78
CHOP and ASF1a
HIRA in KOA chondrocytes
inhibit the aging and apoptosis of KOA chondrocytes
