SNAI1 and colorectal carcinoma: Under hypoxia, dexamethasone treatment inhibits HIF-1α protein levels and decreases mRNA levels of hypoxia-induced SNAIL, SLUG, and TWIST1, and transcriptional factors involved in EMT, as well as the hypoxia-induced integrin αVβ6 protein, a well-known EMT marker for CRC cells [102].
