Fig. 1: WTAP is upregulated in PCa tissues.

A Representative images of WTAP staining by Immuno-histochemistry (IHC) in PCa tissues or prostate normal tissues from a tissue microarray, which contained 60 pairs of patients’ tissues. B, C WTAP staining score was increased in tumors compared to adjacent normal tissues, but had no significant change in different grades. ns, not significant. D WTAP is over-expressed in PCa tumors (n = 493) compared with prostate normal tissues (n = 52) in the TCGA dataset. *P < 0.05. E WTAP protein expression between normal and cancerous specimens was detected by Western blotting assay. The relative WTAP quantification of the Western blotting was measured by using ImageJ software. WTAP expression was increased in Patient 1, Patient 3, and Patient 4.
