Berberine 23-32 protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens 136-140 34687898-1 2022 OBJECTIVE: We investigated the effect of berberine, a natural plant product that can activate AMP-activated protein kinase (AMPK), on OA development and associated pain in mice. Berberine 41-50 protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens 124-128 34687898-2 2022 DESIGN: Human primary knee chondrocytes were utilized to investigate how AMPK is activated by berberine. Berberine 94-103 protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens 73-77 34687898-8 2022 RESULTS: Berberine induced phosphorylation of AMPKalpha (Thr172) via liver kinase B1 (LKB1), the major upstream kinase of AMPK, in chondrocytes in vitro. Berberine 9-18 protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens 122-126 34687898-11 2022 IHC analysis of WT DMM knee cartilage further revealed that berberine inhibited concomitant loss of expression and phosphorylation of AMPKalpha and expression of SIRT1 and SIRT3, suggesting an important role of activation of AMPK signaling in mediating beneficial effect of berberine. Berberine 60-69 protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens 225-229 34687898-11 2022 IHC analysis of WT DMM knee cartilage further revealed that berberine inhibited concomitant loss of expression and phosphorylation of AMPKalpha and expression of SIRT1 and SIRT3, suggesting an important role of activation of AMPK signaling in mediating beneficial effect of berberine. Berberine 274-283 protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens 225-229 34687898-12 2022 CONCLUSIONS: Berberine acts through AMPK to reduce joint structural damage and pain associated with post-traumatic OA in mice in vivo. Berberine 13-22 protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens 36-40
