WebCytokeratins play an important structural and protective role in maintaining the integrity of the epithelium of the anterior segment of the eye. Defined subsets of individual cytokeratin pairs are characteristically expressed, depending on the type of epithelial cell tissue and level of differentiation. WebWe investigated the mRNA and protein expression of nine CKs in melanoma cell lines and tissues, in particular the prognostic significance of CK18 mRNA expression. Reverse transcription (RT)-PCR (CK6–10, 14 and 18–20), in-situ hybridization (ISH) (CK18), and western blotting (CK18 and pan-cytokeratin AE1/AE3) were performed on MM cell lines ...
