introduction: transforming growth factor-beta 1 (tgf-β1) is a pleiotropic cytokine with potent anti-inflammatory property, which has been considered as an essential risk factor in the inflammatory process of ischemic stroke (is), by involving in the pathophysiological progression of hypertension, atherosclerosis, and lipid metabolisms. -509c/t tgf-β1 gene polymorphism has been found to be assoc...

Transforming growth factor alpha (TGF-α) is a protein that in humans is encoded by the TGFA gene. As a member of the epidermal growth factor (EGF) family, TGF-α is a mitogenic polypeptide. The protein becomes activated when binding to receptors capable of protein kinase activity for cellular signaling. TGF-α is a transforming growth factor that is a ligand for the epidermal growth factor recept...

acute myeloblastic leukemia is the most frequent cancer in adults and the patients have a wide range of sub-classes. hla dr negative cases represent one of the major immune-phenotypic classes.  hla-dr is routinely used to distinguish acute promyelocytic leukemia (apl) from other aml subclasses based on the immunophenotype. the tgf-b signaling pathway, as a critical regulator, guides different v...

Understanding how the regulation of growth factor pathways alters during prostate cancer (PC) progression may enable researchers to develop targeted therapeutic strategies for advanced disease. PC progression involves the shifting of cells from androgen-dependent growth to an androgen-independent state, sometimes with the loss or mutation of the androgen receptors in PC cells. Both autocrine an...

A heteronuclear NMR study of human transforming growth factor alpha (TGFalpha) in complex with the epidermal growth factor receptor extracellular domain (EGFR-ED) provided an effective method for delineating the relative contributions of the residues of the ligand to its affinity for the receptor. In conjunction with previously obtained mutagenesis data, these results indicate that while a larg...

background: osteoarthritis is one of the most common diseases in middle‑aged populations in the world and could become the fourth principal cause of disability by the year 2020. one of the critical properties for cartilage tissue engineering (te) is the ability of scaffolds to closely mimic the extracellular matrix and bond to the host tissue. therefore, te has been presented as a technique to ...

For elucidation of the mechanisms by which growth factors and cytokines affect renal epithelial cells, gene array analysis of renal cells cultured in the presence of transforming growth factor-beta1 (TGF-beta1) was performed. Many genes that were not previously considered to be involved in renal cell biologic processes were affected, one of which was jagged-1. The jagged ligand/notch receptor f...

objective(s): herbal medicines are promising cancer preventive candidates. it has been shown that punica granatum l. could inhibit angiogenesis and tumor invasion. in this study, we investigated whether the anti-angiogenic effect of pomegranate peel extract (ppe) is partly attributable to peroxisome proliferator-activated receptors (ppars) activation in the human umbilical vein endothelial cell...

baluchi sheep is considered as the most common breed in iran, constituting about 30% of total sheep population, approximately 15 million heads. this research was designed to study the incidence of mutation in two loci of igf-i (exon 3) and adrb3 (intron) along with their association with body weight traits in baluchi sheep population. following dna extraction from 190 baluchi sheep, two pairs o...
