Vitamin D Inhibits colorectal cancer cell proliferation, migration and invasion via downregulating the Notch1 pathway

Abstract

Due to its high incidence and mortality rates, colorectal cancer (CRC) has become the focus of research. Vitamin D has anticancer functions in a variety of cancers, but the relationship between vitamin D status and CRC risk and survival is inconclusive. The purpose of this study was to explore the effect of vitamin D on the proliferation and invasion of CRC cells to find an effective way to treat CRC. The results showed that vitamin D could inhibit SW480 cell progression in vitro. The results showed that vitamin D significantly blocked the Notch1 pathways by decreasing NOTCH1 protein expression. In addition, we found that Notch1 overexpression could significantly reverse the inhibitory effect of vitamin D on SW480 cells. These results reveal novel insights into the mechanisms of vitamin D anticancer activity in CRC development and progression.
