Background and aim: Cytokines are a large family of protein messengers. These proteins induce various cellular responses. Janus kinases (JAKs) are mediators of cytokine, activated JAKs phosphorylate signal transducers, and activators of transcription (STAT) proteins that regulate cell differentiation, proliferation, and apoptosis. Aberrant JAK/STAT signaling is involved in the oncogenesis of se...
Trimethoxyl stilbene (TMS) is a derivative of resveratrol, a compound shown to inhibit development of a variety of tumor types. We aimed to evaluate the effect of TMS on cell proliferation and apoptosis in the A549 non-small cell lung cancer cell line. Growth inhibition rate and colony formation was measured and apoptosis was determined with Hoechst 33258 staining. Protein expression levels of ...
The effect of treatment with a 0.03% fatty acid (FA) cocktail on leptin-receptor-mediated STAT (signal transducers and activators of transcription) activation in the rat insulinoma cell line BRIN-BD11 was investigated. Leptin (10 nM) stimulated the tyrosine phosphorylation of STAT3 and STAT5b. Acute treatment with FAs prevented leptin-stimulated STAT3 tyrosine phosphorylation and significantly ...
Modified LDL is a major cause of injury to the endothelium in diabetes. In the present study, we analyzed the effects on endothelial cells of LDL recovered from type 2 diabetic patients (dm-LDL) or from nondiabetic subjects (n-LDL). Treatment of human umbilical vein endothelial cells with dm-LDL, but not n-LDL, led to the accumulation of cells in G1. To dissect the molecular mechanisms of this ...
Leptin (OB), an adipocyte-secreted circulating hormone, and its receptor (OB-R) are key components of an endocrine loop that regulates mammalian body weight. In this report we have analyzed signal transduction activities of OB-R containing the fatty mutation [OB-R(fa)], a single amino acid substitution at position 269 (Gln --> Pro) in the OB-R extracellular domain that results in the obese phen...
The interferon-inducible DNA sensor IFI16 is involved in the modulation of cellular survival, proliferation, and differentiation. In the hematopoietic system, IFI16 is consistently expressed in the CD34+ stem cells and in peripheral blood lymphocytes; however, little is known regarding its regulation during maturation of B- and T-cells. We explored the role of IFI16 in normal B-cell subsets by ...
