Hypoxia‑induced lactate dehydrogenase A protects cells from apoptosis in endometriosis.

ABSTRACT: The pathological expression and function of lactate dehydrogenase A (LDHA), a key enzyme that converts pyruvate into lactic acid during glycolysis, remains unknown in endometriosis. In the present study, LDHA expression in tissue samples was determined by immunohistochemistry. To examine whether LDHA was induced by hypoxia, primary cultured endometrial stromal cells (ESCs) and glandular epithelial Ishikawa cells were exposed to 1% O2 (hypoxia) or 21% O2 (normoxia). Cellular functions were assessed by flow cytometry, Transwell and Cell Counting Kit‑8 assays in LDHA‑silenced ESCs and Ishikawa cells. Mitochondrial functions were evaluated using mitochondrial membrane potential JC‑1 staining, reactive oxygen species flow cytometric analysis and ATP detection. Additionally, lactic acid producti
