Nesfatin-1 facilitates IL-1β production in osteoarthritis synovial fibroblasts by suppressing miR-204-5p synthesis through the AP-1 and NF-κB pathways

Inhibiting miR-204-5p expression regulates nesfatin-1-induced stimulation of IL-1β production in human OASFs. (A and B) miRNA target prediction software was used to identify miRNAs that potentially bind to the IL-1β 3’-UTR plasmid.  (C) OASFs were incubated with nesfatin-1 and miR-204-5p levels were examined by qPCR. (D) Levels of miR-204-5p in normal and OA synovial tissues retrieved from the GEO dataset. (E and F) Cells were transfected with miR-204-5p mimic, then stimulated with nesfatin-1. IL-1β expression was examined by qPCR and ELISA. (G) Cells were treated with PI3K, Akt, AP-1 and NF-κB inhibitors, then stimulated with nesfatin-1 prior to qPCR analysis of miR-204-5p levels. *p #p
