USP42 expression in breast tissues and its prognostic significance. (A) Comparison of USP42 mRNA expression in breast cancer tissues and normal breast tissues from the TCGA and GTEx databases. (B) Differential USP42 protein expression in breast carcinoma tissues compared with paired normal tissues. (C) Kaplan–Meier survival analysis of breast cancer patients stratified with by high and low USP42 expression based on TCGA data analyzed using GEPIA. (D) Representative immunohistochemical staining for USP42 in breast carcinoma tissues and paired normal tissues. Scale bars, 50 μm (magnification, ×200). (***: p < 0.001).
