We therefore examined the effect of cisatracurium on SLUG, SNAI-1, E-Cadherin (EMT marker) and CALD1 (a protein implicated in structural conformation of ECM) mRNA and protein expression levels in CRC ex vivo and in vivo by employing qRT-PCR and western blot. The gene discussed is SNAI1; the disease is colorectal carcinoma.
