Figure 6. miR-502 was down-regulated in CRC clinical samples.
Twenty-three pairs of tumor and normal tissue from CRC patients were used, and miR-502 and Rab1B levels were quantified by real-time qRT-PCR and normalized to the internal control RNU44 and GAPDH respectively. The miR-502 and Rab1B levels in tumor tissues were compared to corresponding normal tissues.
