As shown in Figure 1A, BFSP1 mRNA expression was significantly elevated in several malignancies, including LIHC, cholangiocarcinoma, colon adenocarcinoma, esophageal carcinoma, head and neck squamous cell carcinoma, and rectal adenocarcinoma, compared with their corresponding normal tissues. This evidence concerns the gene BFSP1 and cholangiocarcinoma.
