Lysine‐specific demethylase 1 activation by vitamin B2 attenuates efficacy of apatinib for proliferation and migration of gastric cancer cell MGC‐803

B vitamins play an essential role in the biosynthesis of nucleotides, replication of DNA, supply of methyl‐groups, growth and repair of cells, aberrancies of which have all been implicated in carcinogenesis. Although the potential role of vitamin B in relation to the risk of cancer, including breast...

Description
Summary:B vitamins play an essential role in the biosynthesis of nucleotides, replication of DNA, supply of methyl‐groups, growth and repair of cells, aberrancies of which have all been implicated in carcinogenesis. Although the potential role of vitamin B in relation to the risk of cancer, including breast, and colorectal cancer, has been investigated in several observational studies, the mechanism of action is still unclear. In this study, vitamin B2 exhibited efficient activation of LSD1 by occupying the active sites where FAD stands. Interestingly, vitamin B2 significantly downregulated expression of CD86, a sensitive surrogate biomarker of LSD1 inhibition, and showed marked activation of gastric cancer cell migration and invasion. Meanwhile, vitamin B2 induced activation of LSD1 may attenuate the proliferation inhibition, and anti‐migration effects of apatinib in gastric cancer cells. These findings suggested that vitamin B supplementation may interfere with the efficacy of apatinib in patients with gastric cancer. 1. Vitamin B2 exhibited efficient activation of LSD1 by occupying the active sites where FAD stands. 2. Vitamin B2 can promote the proliferation and migration of MGC‐803 cells. 3. Vitamin B2 induced activation of LSD1 may attenuate the proliferation inhibition and anti‐migration effects of apatinib in gastric cancer cells.
