Cytokeratin expression
WebThe type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. Unlike its related family members, this smallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells. 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 ...
