In the mouse tumour tissues, IHC analysis revealed that increased expression of SNAIL, VE‐cadherin and vimentin was observed in the HepG2‐LOXL2 cell‐xenograft tumours compared with the HepG2‐control cell‐xenograft tumours, whereas LLGL2 and E‐cadherin were expressed at lower levels. The gene discussed is SNAI1; the disease is neoplasm.
