The microtubule, F-actin, and intermediate filament systems are often studied as isolated systems, yet the three display mutual interdependence in living cells. To overcome limitations inherent in analysis of polymer-polymer interactions in intact cells, associations between these systems were assessed in Xenopus egg extracts. In both fixed and unfixed extract preparations, cytokeratin associat...
The distinction between benign and malignant thyroid tumors is critical for the management of patients with thyroid nodules. We applied immunohistochemical staining for galectin-3, HBME-1, cytokeratin 19 (CK19), high molecular weight cytokeratin (HMWCK), cyclin D1 and p27(kip1) in 295 thyroid lesions to determine their diagnostic accuracy. The expression of all markers was significantly associa...
Change in Cytokeratin 19 Fragment Level According to the Severity of Pulmonary Alveolar Proteinosis.
BACKGROUND Normal urothelium is characterised by terminally differentiated superficial cells, which express cytokeratin 20 in the cytoplasm. In contrast, cultured human stratified urothelium, which does not undergo complete terminal differentiation of its superficial cells, does not express cytokeratin 20. If spinal cord injury (SCI) affects urothelial differentiation or induces squamous or oth...
The cytokeratin filament network is intrinsically dynamic, continuously exchanging subunits over its entire surface, while conferring structural stability on epithelial cells. However, it is not known how cytokeratin filaments are remodeled in situations where the network is temporarily and spatially restricted. Using the tyrosine phosphatase inhibitor orthovanadate we observed rapid and revers...
