CircHIPK3 was highly expressed in OA chondrocytes compared with normal chondrocytes/cells based on RT-qPCR. Functional assays in OA chondrocytes showed that CircHIPK3 affected apoptosis through the miR-124/SOX8 axis.
Low expression of CircRNA HIPK3 promotes osteoarthritis chondrocyte apoptosis by serving as a sponge of miR-124 to regulate SOX8.
