Compared with other treatments, PDMP was most effective in prolonging survival time (P < 0.05), inhibiting tumor growth (P < 0.05), decreasing expression of CD133 (P < 0.05), CD31 (P < 0.05), and aldehyde dehydrogenase 1 (ALDH1) (P > 0.05), inducing G1 phase arrest (P < 0.05), increasing the apoptosis rate (P < 0.05), and in expressing ATM and γ-H2AX (P < 0.05). This evidence concerns the gene PROM1 and neoplasm.
