BACKGROUND & AIMS Identification of disease severity remains a challenge in the management of non-alcoholic steatohepatitis (NASH). Cytokeratin-18 (CK18), is a recently developed non-invasive biomarker for NASH. We aimed to assess the performance of CK18 in disease severity prediction among Taiwanese NASH patients. METHODS A total of 76 biopsy-proven NASH patients (54 males, age = 41.0 ± 13.5...

A 40-kD protein kinase C (PKC)epsilon related activity was found to associate with human epithelial specific cytokeratin (CK) polypeptides 8 and 18. The kinase activity coimmunoprecipitated with CK8 and 18 and phosphorylated immunoprecipitates of the CK. Immunoblot analysis of CK8/18 immunoprecipitates using an anti-PKC epsilon specific antibody showed that the 40-kD species, and not native PKC...

Cytokeratin 18 (CK18) protein was identified as an airway epithelial cell autoantigen associated with nonallergic asthma. Cleavage of CK18 protein by caspase-3 is a marker of early apoptosis in epithelial cells. It has been shown that the expression of active caspase-3 was increased in bronchial epithelial cells of asthmatic patients, when compared with healthy controls. To investigate the anti...

OBJECTIVE To determine whether raised levels of antibodies to CK18 in patients with RA are associated with ischaemic heart disease (IHD). METHODS IgA, IgG, and IgM antibodies to CK18 were measured by enzyme linked immunosorbent assay (ELISA) in patients with RA with (n = 34) or without (n = 28) IHD. The relationship between CK18 antibody levels and markers of inflammatory and/or cardiovascula...

BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is one of the critical public health problems in China. The full spectrum of the disease ranges from simple steatosis and nonalcoholic steatohepatitis (NASH) to cirrhosis and hepatocellular carcinoma(HCC). The infiltration of inflammatory cells characterizes NASH. This characteristic contributes to the progression of hepatitis, fibrosis, cirrh...

INTRODUCTION Severe sepsis, septic shock, and resulting organ failure represent the most common cause of death in intensive care medicine, with mortality ranging from 40% to 70%. It is still unclear whether necrosis or apoptosis plays the predominant role in severe sepsis. Determining the prevalent mode of cell death would be valuable, as new therapeutic agents (eg, antiapoptotic drugs such as ...

background serum apoptotic cytokeratine 18 neoepitope m30 (ck-18 m30) and matrix metalloproteinase 2 (mmp-2) have been popular markers for detecting liver fibrosis in recent years. ck-18 is a major intermediate filament protein in liver cells and one of the most prominent substrates of caspases during hepatocyte apoptosis. mmp-2 plays an important role in tissue remodeling and repairing process...

Background & Objective: The common epithelial ovarian tumors are classified into serous, mucinous, clear cell, endometrioid, the Brenner, mixed, and undifferentiated types. Cytoskeleton intermediate filament composition of ovarian tissues indicates that the cytokeratin and vimentin are observed in ovarian surface epithelium along with the common ovaria...

Tumor necrosis factor-related apoptosis- inducing ligand (TRAIL) -induced apoptosis, in transformed human breast epithelial MCF-7 cells, resulted in a time-dependent activation of the initiator caspases-8 and -9 and the effector caspase-7. Cleavage of caspase-8 and its preferred substrate, Bid, preceded processing of caspases-7 and -9, indicating that caspase-8 is the apical initiator caspase i...
