background and aims. the role of cytokines in the immunopathogenesis of oral lichen planus (olp) has received much attention. the aim of this study was to evaluate the serum levels of tnf-α and tgf-β in patients with olp in an iranian population. materials and methods. thirty-two patients with olp and 32 age-matched healthy volunteers as a control group were included in this study. serum tests ...

Objective(s): Transforming growth factor alpha (TGF-α) has been shown to modulate the gastric acid secretion. Therefore, the aim of the present study was to investigate the effect of sodium hydrosulfide (NaHS) on TGF-α expression in gastric mucosa in rats. Materials and Methods: Eighteen rats were randomly divided into 3 groups (6 per group). To determine the effect of NaHS on gene and protein ...

background: tnf-α is a multifunctional proinflammatory cytokine and tgf-β1 is a secretory protein controlling epithelial proliferation and differentiation. keratocyst presents an aggressive behavior and a growth mechanism different from that of radicular cyst. aim: in this line, the present study aimed at evaluating tnf-α and tgf-β1 level and its association with histopathological findings in t...

BACKGROUND The role of transforming growth factor β1 (TGF-β1) and tumor necrosis factor α (TNF-α) in asthma is unclear. The aim of this study was to assess the relationships among polymorphisms, clinical phenotypes, and the serum levels of TGF-β1 and TNF-α. METHODS Polymorphisms of promoter of TGF-β1 (C-509T locus) and TNF-α (G-308 A locus; rs 1800629) in 217 asthmatic patients and 110 health...

objective(s): pulmonary fibrosis (pf) is the most common outcome of a collection of diverse lung disorders known as interstitial lung diseases. it is proposed that alterations in the levels of fibrogenic mediators and the profibrotic/antifibrotic imbalance play a substantial role in the progression of pf in animal models and possibly in humans. caffeic acid phenethyl ester (cape), an active com...

Peroxiredoxin 1 (PRDX1) participates in tumor cell proliferation, apoptosis, migration, invasion, and the epithelial-to-mesenchymal transition (EMT). This study aimed to investigate effect of PRDX1 on EMT airway epithelial cells stimulated with lipopolysaccharide (LPS) transforming growth factor-beta (TGF-β1). overexpression significantly increased proliferation migration human bronchial (BEAS-...

objective: stroke is most important cause of death and disability in adults. the hippocampal ca1 and sub-ventricular zone neurons are vulnerable to ischemia that can impair memory and learning functions. although neurogenesis normally occurs in the dentate gyrus (dg) of the hippocampus and sub-ventricular zone (svz) following brain damage, this response is unable to compensate for severely dama...

Renal fibrosis is a crucial pathological phenomenon of chronic kidney disease (CKD) that contributes to the progressive loss renal function. Monocarboxylate transporter 1 (MCT1) plays an important role in clear cell carcinoma; however, MCT1 inhibitor alpha-cyano-4-hydroxycinnamic acid (α-CHCA) remains unclear. In this study, we evaluated α-CHCA, inhibitor, treating associated with CKD. We used ...

Background: Mesenchymal stem cells (MSCs) and transforming growth factor-β1 (TGF-β1) molecules are well known for their immunomodulatory properties and their function in tissue regeneration and remodeling. Objectives: To evaluate the interaction of TGF-β1 engineered MSCs with T cells and dendritic cells (DCs) and their modulatory effect on the immune response. Methods: MSCs and DCs were generat...
