Moreover, the TCGA database showed that lncRNA WFDC21P was significantly upregulated in 18 out of 27 tumors, including bladder cancer, breast cancer, colon cancer, esophageal cancer, pancreatic cancer, and GC et al. (Fig. 1B, C), offering the possibility for WFDC21P to be a pan-oncogene. Here, WFDC21P is linked to breast cancer.
