Furthermore, by stratifying the RETNLB expression levels in CRC biopsies patients’ and in healthy subjects according to the age, we showed a significant reduction both considering the whole cohort of samples (p = 0.0146; r = −0.066) and in patients with CRC (p = 0.010; r = −0.076) but not in healthy subjects (p = ns, r = −0.05) (Fig. 2). This evidence concerns the gene RETNLB and colorectal carcinoma.
