background chemokines play important roles in immune system activation against microbial infections. objectives the current study aimed to evaluate seminal levels of cxc chemokines cxcl1, cxcl9, cxcl10 and cxcl12 in chlamydia trachomatis infected patients. materials and methods the c. trachomatis infection was determined employing polymerase chain reaction (pcr)-based methods. seminal concentra...
Background: Alopecia Areata (AA) is a non-scarring, autoimmune disorder which causes hair loss. Inflammatory reactions are involved in hair loss of the scalp and/or body. The involvement of chemokine receptors in the pathogenesis of AA is well defined among which, CXCL1 acts on neutrophils and CXCL9, CXCL10 and CXCL12 and serve as T lymphocytes recruiters. Objective: To study the serum levels o...
Ultraviolet (UV)-induced DNA damage and skin inflammation are well-known mechanisms of carcinogenesis. However, the extent to which contributes UV-induced carcinogenesis is unknown. The xeroderma pigmentosum group A (XPA) model mice (Xpa-KO mice) deficient in repair systems, making them susceptible cancer. We previously reported that blood levels CXCL1, a neutrophil attractant chemokine, increa...
BACKGROUND AND AIMS CXCL1 (CXC chemokine-ligand-1) is a ligand for CXC chemokine receptor 2 expressed on hepatic stellate cells (HSC). Thus, CXCL1 might contribute to HSC activation and fibrogenesis. In the present study, we investigated the influence of the CXCL1 rs4074 polymorphism on the occurrence of alcohol induced liver cirrhosis and hepatocellular carcinoma (HCC). METHODS The study inv...
Chemokines, including chemokine (C-X-C motif) ligand 1 (CXCL1), regulate tumor epithelial-stromal interactions that facilitate tumor growth and invasion. Recently, several studies have linked CXCL1 expression to bladder cancer (BCa). In this study, we aimed to determine if increased levels of urinary CXCL1 were found in BCa patients. Voided urines from 86 subjects, cancer subjects (n = 43), non...
The chemokine CXCL1 is elevated in plasma and ascites from patients with ovarian cancer. We have previously shown that CXCL1 is a marker of phosphatidylinositol 3-kinase signalling in epithelial ovarian cancer (EOC) cell lines, a pathway that is commonly activated in ovarian tumours. To investigate whether CXCL1 also has functional significance in ovarian cancer, this chemokine was either down-...
The term "interstitial pneumonia with autoimmune features" (IPAF) has been recently proposed. We here investigate the clinical characteristics of IPAF and evaluate the clinical implications of CXCL1-CXCR2 axis in IPAF. An increased plasma level of CXCL1 was exhibited in IPAF compared to idiopathic interstitial pneumonia (IIP), chronic obstructive pulmonary disease (COPD), and healthy controls. ...
Severe bacterial sepsis leads to a proinflammatory condition that can manifest as septic shock, multiple organ failure, and death. Neutrophils are critical for the rapid elimination of bacteria; however, the role of neutrophil chemoattractant CXCL1 in bacterial clearance during sepsis remains elusive. To test the hypothesis that CXCL1 is critical to host defense during sepsis, we used CXCL1-def...
Lung cancer cells express different chemokines and chemokine receptors that modulate leukocyte infiltration within tumor microenvironment. In this study we screened several mediators/growth factors on CXCL1 release in human carcinoma epithelial cells. Of the tested mediators, VEGF was found to have a robust increase in causing CXCL1 release. VEGF stimulated CXCL1 release and mRNA expression in ...
In this study, we investigated the value of measurement of the chemokine CXCL1 in clinical management of hepatocellular carcinoma (HCC) and its possible role in the molecular pathogenesis of HCC. High CXCL1 expression predicted recurrence in HCC patients and promoted tumor progression in both in vivo and in vitro experimental systems. Overexpression of CXCL1 increased mitochondrial metabolism a...
