RGCC and colorectal carcinoma: In order to identify the correlation of miR-656-3p and selected four genes (SGPP1, RORA, ITGB8, and RGCC), the mRNA expression level of miR-656-3p, SGPP1, RORA, ITGB8, and RGCC in 119 CRC patient tissues were detected by qRT-PCR, and U6 was set as the internal reference.
