Fig. 5From: Icariin alleviates osteoarthritis through PI3K/Akt/mTOR/ULK1 signaling pathwayULK1 knockdown promotes IL-1β-induced inflammation in OA chondrocytes. A Representative Western blot images of MMP-3 and collagen II after ULK1 knockdown. B Quantitation of MMP-3, collagen II. C MMP-3, aggrecan mRNA levels were determined using real-time PCR. Data are presented as means ± SD (n = 3). *P < 0.05 versus control group (IL-1β group), #P < 0.05 versus shRNA/NC groupBack to article page
