Typical immunohistochemical staining samples and the corresponding staining intensities of HMGA2 in ccRCC tissues. Notes: (A) Renal carcinoma tissues showed strong nuclear HMGA2 staining. (B) Renal carcinoma tissues showed moderate nuclear HMGA2 staining. (C) Renal carcinoma tissues showed weak HMGA2 staining. (D) Renal carcinoma tissues showed negative HMGA2 staining. Bars: 50 μm. Abbreviations: HMGA2, high-mobility group AT-hook 2; ccRCC, clear cell renal cell carcinoma. High expression of HMGA2 predicts poor survival in patients with clear cell renal cell carcinoma: OncoTargets and therapy. Not altered. CC.
