Fig. 1: Downregulation of ARHGAP15 in CRC tissues.

a, b ARHGAP15 mRNA expression was analyzed based on two public available data sets: GSE9348 (a) and TCGA CRC (b). c The mRNA levels of ARHGAP15 on our own cohort were determined using qRT-PCR. d The protein levels of ARHGAP15 were determined by immunohistochemistry staining. Scale bar: 100 μm. e Kaplan–Meier survival curves showing the difference of survival time between patients with low and high expression of ARHGAP15 on CRC samples from 95 patients. ****P < 0.0001
