Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Tyr10 of human LDHA protein. Antibodies are purified by protein A and peptide affinity chromatography.

Lactate dehydrogenase (LDH) catalyzes the interconversion of pyruvate and NADH to lactate and NAD+. When the oxygen supply is too low for mitochondrial ATP production, this reaction recycles NADH generated in glycolysis to NAD+, which reenters glycolysis. The major form of LDH found in muscle cells is the A (LDHA) isozyme. The LDHA promoter contains HIF-1α binding sites (1). LDHA expression is induced under hypoxic conditions (2). During intensive and prolonged muscle exercise, lactate accumulates in muscle cells when the supply of oxygen does not meet demand. When oxygen levels return to normal, LDH converts lactate to pyruvate to generate ATP in the mitochondrial electron transport chain.


Recent studies indicate that LDHA is phosphorylated at Tyr10 and Tyr83 by the receptor tyrosine kinase FGFR1 (3). Phosphorylation at Tyr10 up-regulates the activity of LDHA and is found in a variety of human cancer cells (3). Results further suggest that tyrosine phosphorylation regulates the NADH/NAD+ redox homeostasis and thus promotes the Warburg effect and tumor cell growth (3).

最近的研究表明LDHA被受体酪氨酸激酶FGFR在Try10和Tyr83磷酸化(3)。Tyr10的磷酸化可以上调LDHA的活性,并且在多种人类癌细胞中发现(3)。研究结果进一步推测酪氨酸磷酸化调节NADH/NAD+ redox的动态平衡,并且促进Warburg效应和肿瘤细胞生长(3)。
