To assess the clinical significance of RRP15 in CRC progression, we analyzed RRP15 mRNA expression in CRC tissues using the online database (http://ualcan.path.uab.edu/index.html), and found that the mRNA level of RRP15 in CRC tissues were significantly higher than that in normal tissues (Fig. S1A, B). The gene discussed is RRP15; the disease is colorectal carcinoma.
