We identified differences in markers quantity based on grading, where CD133 in CRC was present in lower amount in G1 compared to G2 (Mann-Whitney U Test P = 0.0248) and CD133 in CLM had lower expression in G1 compared to combined G2 and G3 stage (Mann-Whitney U Test P = 0.0470) (Figures 4(a) and 4(b)). The gene discussed is PROM1; the disease is colorectal carcinoma.
