In addition, calcitriol and the calcitriol analogue MART-10 may also inhibit the expression of SLUG, SNAIL1, SNAIL2, TWIST1, and ZEB1 molecules and increase the expression of mesenchymal markers fibronectin, LEF-1, and claudin-7 in tumour cells, which determines the increase in E-cadherin and p120-catenin. The gene discussed is SNAI2; the disease is neoplasm.
