RPA2 and neoplasm: In addition, we analysed the gene expression data of HNSC cases in the TCGA data set, which suggested that RPA1 and RPA3 were up‐regulated in HNSC tissues compared with non‐tumour tissues (Fig. 1D and F), whereas RPA2 expression did not significantly differ between HNSC and non‐tumour tissues (Fig. 1E).
