CDH1 and exocrine pancreatic carcinoma: The stabilising function of IQGAP1 on the turnover of E-cadherin/catenin complexes was underlined by the downregulated IQGAP1 expression by siRNAs which resulted in a disassembly of the E-cadherin/β-catenin complex and reduced concentration of E-cadherin in the analysed pancreatic carcinoma cells.
