Immunohistochemistry: Pyruvate Dehydrogenase E1-alpha subunit [p Ser293] Antibody (JE58-27) [NBP3-32787] - Immunohistochemical analysis of paraffin-embedded human renal clear cell carcinoma tissue with Rabbit anti-Pyruvate Dehydrogenase E1-alpha subunit antibody (NBP3-32787) at 1/500 dilution.

The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32787) at 1/500 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background: Pyruvate Dehydrogenase E1-alpha subunit

Pyruvate Dehydrogenase E1-alpha subunit (PDHE1 alpha) is a member of the pyruvate dehydrogenase complex (PDC) and is a nuclear-encoded mitochondrial matrix multienzyme complex that provides the primary link between glycolysis and the tricarboxylic acid (TCA) cycle by catalyzing the irreversible conversion of pyruvate into acetyl-CoA. The PDH complex is composed of multiple copies of 3 enzymes: E1 (PDHA1 or PDHE1), dihydrolipoyl transacetylase (DLAT), and dihydrolipoyl dehydrogenase (DLD). The E1 enzyme is a heterotetramer of 2 alpha and 2 beta subunits. The E1-alpha subunit contains the E1 active site and plays a key role in the function of the PDH complex. Enhanced expression of pyruvate dehydrogenase kinase-1 (PDK-1) results in phosphorylation of PDHE1 alpha at Serine 293, which in turn produces nearly complete inhibition of the pyruvate dehydrogenase complex (PDC). A recent study shows that inhibition of PDC activity in cancer cells restores normoxic stablization of HIF-1 alpha by glycolytic metabolites.
