IDH3A and cervical squamous intraepithelial neoplasia: A variety of proteins related to metabolism were differentially expressed after treatment with CIN, including up-regulation of proteins from L-lactate dehydrogenase, acetyltransferase component of pyruvate, succinate dehydrogenase hydrophobic membrane anchor subunit, acetyltransferase component of pyruvate dehydrogenase complex, and downregulation of proteins from isocitrate dehydrogenase, phosphoglycerate kinase, phosphoglucomutase, 2,3-bisphosphoglycerate-independent phosphoglycerate mutase, and glucose-1-phosphatase.
