SNAI1 and nasopharyngeal carcinoma: In consideration of the pivotal roles that EMT-related transcription factors (EMT-TFs) play in the process of NPC metastasis, we examined the expression levels of some common EMT-TFs regulators (SNAIL, SLUG, CTNNNB1, TWIST1, FOXC2, ZEB1 and ZEB2) after up-regulating BART13-3p expression.
