| Disease Name: | Osteoarthritis |
| Sample: | OA patients/animal cartilage tissues, chondrocyte model |
| Dysfunction Pattern: | Interaction(miR-29a- 3p/FOXO3 Axis) |
| Validated Method: | Western Blot//CCK8//qRT-PCR//Flow Cytometry//ELISA |
| Description: | The expression level of POU3F3 was decreased in OA patients/animal cartilage tissues and IL-1β-stimulated in vitro chondrocyte model. Mechanistically, Luciferase reporter and RNA immunoprecipitation (RIP) assays indicated that miR-29a-3p could directly bind to POU3F3, and FOXO3 was a target gene of miR-29a-3p. Functional rescue assays confirmed this POU3F3/miR-29a-3p/FOXO3 axis in chondrocytes during OA occurrence. |
| Causality: | Yes |
| Causal Description: | POU3F3 overexpression inhibited IL-1β-induced injury of chondrocytes, enhancing cell viability, suppressing apoptosis and inflammatory cytokine secretion, rescuing metabolic dysfunction, and restraining autophagy in vitro. Furthermore, intraarticularly delivery of lentivirus containing POU3F3 alleviates the damage in mouse OA model in vivo. |
