    Decreased lactylation of pyruvate dehydrogenase E1 component subunit alpha (PDHA1) at Lys336 facilitates its dephosphorylation and drives a metabolic shift. (A) Pulmonary vascular endothelial cells (PVECs) were treated with D-galactose (D-gal; 30 mg/ml) for 24 h. Cell lysates were immunoprecipitated with PDHA1 antibody-conjugated Protein A/G Agarose, followed by Western blot for the lactylation of PDHA1 using anti-pan-lactyl antibodies. (B) PDHA1-K336R mutation increased pyruvate dehydrogenase complex (PDHC) activity in mouse primary PVECs. (C) Primary murine PVECs were cotransfected with wild-type PDHA1 WT or PDHA1-K336R mutant. Cell lysates were immunoprecipitated with PDHA1 antibody-conjugated Protein A/G Agarose, followed by a Western blot for the phosphorylation of PDHA1 using pan <t>p-serine</t> antibodies. (D and E) Lactyl-lysine protein level and the phosphorylation level at PDHA1 S293 were determined. (F and G) Quantification of intracellular and extracellular lactate levels.
