Quantification of CK18, cell contact proteins N-cadherin, occludin, ZO-1, and caspases as well as IL18 by RT-PCR. Expression levels were determined by quantification of PCR products after electrophoretic separation (A) using the Image J software (B). PPIA (Peptidylprolyl Isomerase A) was used for standardization of loading.
