Background Information
Cytokeratin 8 (CK8) is a protein that belongs to the cytokeratin family, which is a group of structural proteins found in the intracytoplasmic cytoskeleton of epithelial cells. CK8 forms intermediate filaments within the cytoplasm of simple epithelial cells, typically as a dimer with cytokeratin 18 (CK18). These filaments provide a stabilizing framework that helps determine cell shape and enables cells to cope with mechanical stress. CK8/CK18 filaments also serve as a mesh of "paths" for signaling molecules, metabolites, and pathogens to travel within the cell in an organized manner. CK8 is expressed in various epithelial tissues and is particularly associated with glandular and simple epithelia. Its expression is also a significant marker in several types of cancer, including lung and esophageal cancer, where it can indicate tumor progression and poor prognosis.
