HIF1A and gastric cancer: To test whether flavonoid polyphenol wogonin can stop gastric cancer cells from multiplying in vitro, researchers used SGC-7901 cells treated with flavonoid polyphenol wogonin, as a result, HIF-1α and MCT-4 expression was inhibit, therefore cell proliferation and pathogenesis were inhibited (Tai et al., 2005; Wang et al., 2019).
