The proportion of HIF-1α-positive cells in tumor tissues of mice in group M was significantly higher than that in group C, group C+W, and group W, and the difference was statistically significant (P < 0.05); the proportion of HIF-1α-positive cells in tumor tissues of mice in group C+W was significantly lower than that in group C and group W, and the difference was statistically significant (P < 0.05). This evidence concerns the gene HIF1A and neoplasm.
