Fig. 6From: Specificity protein 1-mediated ACSL4 transcription promoted the osteoarthritis progression through suppressing the ferroptosis of chondrocytesSp1-regulated Ascl4 levels in the IL-1β-treated HCCs. Sp1 levels in the IL-1β-treated HCCs were detected by RT-qPCR assay (A). Transfection efficiency of si-Acsl4 and oe-Sp1 was analyzed by RT-qPCR (B). After si-Sp1 C, E or oe-Sp1 D and F transfection, the Ascl4 levels in the IL-1β-treated HCCs were detected by RT-qPCR and Western blotBack to article page
