Real-time PCR evaluation of CD147 and MMP-11 mRNA expression in 14 pairs of CRC tissues and matched normal mucosa. a mRNA expression of CD147 in tumor tissues was higher than that in normal tissues (P = 0.002). b mRNA expression of MMP-11 in tumor tissues was higher than that in normal tissues, too (P = 0.043). The relative quantification (RQ) was calculated using the 2^−ΔΔCtmethod
