After venn intersection, a total of 3 gene candidates, HSD17B1, CYP1B1, and CYP1A1, were identified in three gene sets, including 169 kaempferol-related genes in silico (red background), 129 kaempferol-related genes in vitro (yellow background), and 1181 endometrial cancer-related genes (purple background) (Fig. 3F). This evidence concerns the gene CYP1A1 and endometrial cancer.
