Expression levels of deregulated miR-7, miR-93, miR-141, miR-195, miR-494, and let-7b in human CRC tumors. The relative expression level of miR is represented by log₁₀ (2^−ΔCt); ΔCt = (Ct_miR−Ct_U6b), with U6b as the internal control for normalization. a The samples from early relapsed patients showed significantly increased miR-7 expression levels (P = 0.014). b The samples from early relapsed patients showed significantly decreased miR-93 expression levels (P < 0.0001). c The samples from early relapsed patients showed significantly increased miR-141 expression levels (P = 0.001). d The samples from early relapsed patients showed significantly decreased miR-195 expression levels (P = 0.040). e The samples from early relapse patients showed significantly decreased miR-494 expression levels (P = 0.016). f The samples from early relapsed patients showed significantly decreased let-7b expression levels (P = 0.002)
