Fig. 1From: Circ_0044235 regulates the development of osteoarthritis by the modulation of miR-375/PIK3R3 axisLow level of circ_0044235 in OA cartilage tissues and IL-1β-induced CHON-001 cells. (A) The information of circ_0044235 was shown. (B) DNA gel electrophoresis confirmed the circular structure of circ_0044235. (C and D) Relative circ_0044235 expression in OA cartilage tissues and IL-1β-induced CHON-001 cells was analyzed by qRT-PCR. (E and F) Act D assay or RNase R assay was used to confirm the stability of circ_0044235. *P < 0.05Back to article page
