results our results revealed that the serum levels of tgf-β were significantly increased in chb patients in compare to healthy controls. conclusions according to this result, it may be concluded that high serum levels of tgf-β may be a mechanism by which immune response against hbv is suppressed. background the transforming growth factor-β (tgf-β) is an important cytokine with anti-inflammatory...
the role of angiogenic molecules, like vascular endothelial growth factor (vegf) and fibroblast growth factor (fgf) in tumor angiogenesis was well confirmed. photodynamic therapy (pdt) action is, to very high degree, based on tumor vasculature damage. therefore, it seemed to be important to evaluate growth factor receptors after pdt. the extent of receptor expression was studied by immuno-histo...
introduction: adenotonsillar hypertrophy (ath) may present with growth retardation. insulin-like growth factor 1 (igf-1) mediates the anabolic effects of growth hormone (gh) on tissues. most of the circulating igf-1 molecules are bound to insulin-like growth factor-binding protein 3 (igfbp-3). igf-1 and igfbp-3 serum levels reflect the levels of daily mean serum gh and are used as indices for e...
preeclampsia is an important pregnancy disorder with serious maternal and fetal complications which its etiology has not been completely understood yet. early diagnosis and management of disease could reduce its potential side effects. the vascular endothelial growth factor (vegf) family including vegf-a is the most potent endothelial growth factor which induces angiogenesis and endothelial cel...
conclusions this study shows that bdnf and ngf expression decreases in diabetic neuropathy. however, this decrease can be reversed through endurance training. these results also indicate that endurance training may have a potential role in compensating for neurotrophin deficiency following diabetic neuropathy. objectives this experimental study was designed and carried out at the tarbiat modare...
background: the present study was undertaken to investigate the correlation of epidermal growth factor receptor (egfr) expression with grade of transitional cell carcinoma (tcc). methods: tumor samples of 75 patients from mostafa khomaini hospital with transitional cell carcinoma of the bladder were analyzed by immunohistochemistry for expression of egfr. in this context, we assigned the bladde...
experimental allergic encephalomyelitis (eae), a demyelinating disease induced in the animals parallels multiple sclerosis in human in several aspects, provides a useful model to investigate multiple sclerosis. in this study, we have therefore used this model to study functions of nerve growth factor (ngf) in eae. ngf with considerable effects on neuron survival, proliferation and differentiati...
introduction: carbon nanotubes (cnts) have shown enormous potential in neuroscience. nerve growth factor (ngf)-cnts complex promotes the neuronal growth, however, the underlying mechanism(s) have remained elusive. based on the interplay between ngf and the endocannabinoid system, involvement of the neuroprotective endocannabinoid, 2-arachidonoyl glycerol (2-ag), was investigated in the mechanis...
background and purpose: tgf-β is a potent regulator and suppressor of the immune system and overproduction of this cytokine may contribute to immunosuppression in hiv-infected patients. increasing population of immunosuppressed patients has resulted in increasingly frequent of fungal infections, including oral candidiasis. the aim of this study was to evaluate the plasma levels of tgf-β under i...
background epidermal growth factor (egf) plays a fundamental role in the healing of wounds relating to skin damage, the cornea, and the gastrointestinal tract. objectives the aim of this study is the cloning, expression, and purification of recombinant human egf (rhegf), and an assessment of its activity. materials and methods in the present experimental study, a synthetic pet28a (+) -hegf cons...
