Next, we analysed NMUR1 expression in patients with CRC (Additional file 4) after stratification according to microsatellite stability (MSS—microsatellite stable, MSI—microsatellite unstable) (Fig. 1f), metastasis status classified by the M stage (Fig. 1g) and lymph node invasion status reflected by the N stage (Fig. 1h). The gene discussed is NMUR1; the disease is colorectal carcinoma.
