Consistent with published data [10], SRSF3 was highly expressed in 257 (70.6%) CRC tissues, especially in adenocarcinoma tissues (OR = 2.30, P = 0.040; Supplementary Table 2), and was positively correlated with Ki67 expression, a proliferation marker (P = 0.040; Supplementary Table 2). Here, SRSF3 is linked to colorectal carcinoma.
