Epithelial cells express antimicrobial proteins in response to invading pathogens, although little is known regarding epithelial defense mechanisms during healthy conditions. Here we report that epithelial cytokeratins have innate defense properties because they constitutively produce cytoprotective antimicrobial peptides. Glycine-rich C-terminal fragments derived from human cytokeratin 6A were...

The emergence of recurrent, metastatic prostate cancer following the failure of androgen-deprivation therapy represents the lethal phenotype of this disease. However, little is known regarding the genes and pathways that regulate this metastatic process, and moreover, it is unclear whether metastasis is an early or late event. The individual genetic loss of the metastasis suppressor, SSeCKS/Gra...

background: gastric and colorectal adenocarcinoma are the second and the fifth most common cancers in iran, respectively. expression of cytokeratin 7 (ck7) is established in most malignancies including gastric and colorectal adenocarcinoma. demonstration of ck7 could be related to prognostic factors and help to the better management of the patients. the objective of our study was to evaluate th...

To characterize thymic epithelial cells of SCID (severe combined immunodeficiency) mice in comparison with those of Balb C mice, we did an immunohistochemical study using cortical and medullary epithelial cell specific monoclonal antibodies (MoAbs), Th-3 and Th-4, as well as gel electrophoresis and immunoblotting. The thymi of SCID mice were composed of epithelial cells and a few lymphocytes. M...

Expression of epithelial cytokeratins type 8, 18 and 19 can be used to study smooth muscle cell differentiation during development. We studied the differentiation of smooth muscle cells in the ductus arteriosus before and during intimal thickening and compared the changes occurring in this vessel with the adjoining elastic ascending and descending aorta and the pulmonary trunk. The ductus arter...

Colorectal cancer (CRC) is the second most prevalent cause of cancer-related deaths in the Western world. 5-Fluorouracil (5-FU) is a standard chemotherapeutic drug to treat CRC. However, the response rate is less than 20% and patients who have responded to 5-FU may become resistant. Therefore there is an urgent need to examine the 5-FU response proteins so that patients with no response to 5-FU...

The article presents the main aspects of pathogenesis comorbidity non-alcoholic fatty liver disease and hypertension. These diseases are very often presented as comorbidities in a large number patients can independently impair renal function. According to literature results our own research, role insulin resistance, disorders lipid carbohydrate metabolism, cytokine imbalance, antioxidant defens...

this research was conducted to evaluate the effect of different zinc (zn) sources on performance, bloodmineral and cell counts of zandi lambs. 18 male lambs at weaning were supplemented with two differentsources of zinc, 25 ppm znso4 and 25 ppm zinc-peptide added to the basal diet as control. live bodyweight, weight gain and feed efficiency improved with zn-peptide supplementation (p
