Only limited protein expression data of SNRPB were available, including BRCA, head and neck squamous cell carcinoma (HNSC), kidney renal clear cell carcinoma (KIRC), LIHC, and OV, and the protein expression level of SNRPB was significantly increased in all five tumors (Figure 1C, p < 0.05). This evidence concerns the gene SNRPB and head and neck squamous cell carcinoma.
