Valproic Acid Protects Chondrocytes from LPS-Stimulated Damage via Regulating miR-302d-3p/ITGB4 Axis and Mediating the PI3K-AKT Signaling Pathway.

ABSTRACT: Background: Osteoarthritis (OA) is one of the most common degenerative joint diseases characterized by increased apoptosis and autophagy deficiency. The investigation was performed to examine the effect of valproic acid (VPA) and molecular mechanism related to miR-302d-3p/ITGB4 axis in OA. Methods: The OA clinical samples were obtained from the GEO database to analyze differentially expressed genes. An in vitro OA model was mimicked by LPS in CHON-001 cells. Autophagy-related genes were downloaded from the HADb website, and potential drugs were mined using the CTD website. The upstream factors of ITGB4 were predicted with bioinformatics analysis, which was validated by luciferase activity assay and RIP assay. Cell viability and apoptosis were evaluated using CCK-8 and
