E-cadherin (encoded by CDH1 gene), N-cadherin (CDH2), fibronectin (FN1), matrix metalloproteinase MMP-2/9 (MMP-2/9), occludin (OCLN), SNAIL (SNAI1), SLUG (SNAI2), urokinase-type plasminogen activator (uPA, encoded by PLAU gene), vimentin (VIM), ZO-1 (TJP1), and TWIST (TWIST) are considered as one of markers of cancer invasion and metastasis, therefore we decided to quantitatively assess the influence of tested agents on their mRNA expression levels. The gene discussed is PLAU; the disease is cancer.
