Cytokeratin 5 Information for Pathologists
Molecular weight is 58 kDa. Major partner is CK14, but related to cytokeratin 6 (antibodies are often to CK5/6). Common antibody is 34BE12. Mutations may cause epidermolysis bullosa simplex (Hum Mutat 2006;27:719), Dowling-Degos disease (Am J Hum Genet 2006;78:510). Important in tooth enamel formation (J Biol Chem 2003;278:20293).
Common Uses By Pathologists:
Helps defines a basal-like subtype of invasive ductal carcinoma of the breast that is usually CK5/6+, ER-, PR-, HER2-, EGFR+ with poorer prognosis (Clin Cancer Res 2006;12:1533); associated with premenopausal African American women (JAMA 2006;295:2492), BRCA1 (J Natl Cancer Inst 2003;95:1482, Mod Pathol 2005;18:1321) and brain metastases (Am J Surg Pathol 2006;30:1097). Defines a DCIS subtype with poorer prognosis (Hum Pathol 2007;38:197). Distinguish breast usual ductal hyperplasia (strong staining) from solid papillary DCIS (negative, Hum Pathol 2006;37:787). p63+ and CK5/6+ poorly differentiated metastatic carcinomas are likely to have squamous carcinoma primaries (Am J Clin Pathol 2001;116:823). Distinguish epithelioid mesothelioma (CK5/6+ cytoplasmic staining with perinuclear enhancement) from lung adenocarcinoma (usually CK5/6 negative, Histopathology 2006;48:223); also in pleural effusions (Diagn Cytopathol 2006;34:801).
