dc.description.abstract | Aims: Psoriasis is a chronic inflammatory skin disease and lysophosphatidic acid (LPA) has recently been reported to contribute to its pathogenesis through keratinocyte proliferation. In this study, we investigated the metabolic changes in the LPA-induced keratinocyte hyperproliferation and underlying mechanisms. Main methods: HaCaT or HEKa cells were treated with LPA in the presence or absence of various chemical inhibitors. The glycolysis stress was measured using the Seahorse extracellular flux analyzer. Gene knockdown by siRNA transfection was used to investigate the role of LPAR1, PGAM1, and HIF-1α in LPA-induced metabolic changes. We confirmed the expression of PGAM1 and HIF-1α in imiquimod (IMQ)-induced psoriasis-like BALB/c mice. Key findings: LPA increased aerobic glycolysis; however, treatment with ki16425, or LPAR1 knockdown inhibited LPA-induced glycolysis in HaCaT cells. LPA increased the expression of glycolytic enzyme PGAM1 through LPAR1. PGAM1 knockdown in HaCaT cells suppressed LPA-induced cell proliferation, changes in cell cycle factor expression, and inhibited LPA-induced aerobic glycolysis. LPA sequentially activated AKT, mTOR, its downstream target, p70 S6K, and increased HIF-1α expression through LPAR1. HIF-1α knockdown inhibited LPA-induced PGAM1 expression and aerobic glycolysis. A6730 also decreased LPA-induced activation of mTOR and p70 S6K and LPA-induced increases in HIF-1α and PGAM1 expression. Ki16425 suppressed the increased expression of PGAM1 and HIF-1α in the lesions of IMQ-induced psoriasis-like mice. In primary keratinocytes, LPA/LPAR1 signaling also induced AKT-mediated aerobic glycolysis. Significance: Collectively, the results demonstrated that LPA induces aerobic glycolysis via AKT/mTOR/HIF-1α-dependent PGAM1 expression during keratinocytes proliferation and this might be one of the mechanisms of psoriasis development. © 2022 The Authors | - |
