Co-IP assays with an anti-STAT5A antibody demonstrated that endogenous STAT5A interacted with multiple PDC subunits, including PDHA1, PHDB, DLD, and DLAT in 293T, HeLa (a human cervical cancer cell line), MIHA (a human hepatocyte), and primary mouse hepatocytes (Fig. 1d and Supplementary Fig. 1a–c). This evidence concerns the gene STAT5A and cervical carcinoma.
