INTRODUCTION Blood pressure is lower in females than males. Angiotensin II type-2 receptor (AT2R) induces vasodilation. This study determined whether sex differences in vascular AT2R expression occur and if androgens exert control on AT2R expression in the vasculature. METHODS AT2Rs in the aorta of male and female Sprague-Dawley rats were examined following alteration in androgen levels by go...
Pdgfrb is a direct regulatory target of TGFβ signaling in atrioventricular cushion mesenchymal cells
Cushion formation is the initial step for the development of valvuloseptal structures in mammalian hearts. TGFβ signaling plays critical roles in multiple steps of cushion morphogenesis. We used a newly developed conditional immortal atrioventricular cushion mesenchymal cell line, tsA58-AVM, to identify the TGFβ regulatory target genes through microarray analysis. Expression of ~1350 genes was ...
Signalling by TGFβ superfamily factors plays an important role in tissue growth and cell proliferation. In Drosophila, the activity of the TGFβ/Activin signalling branch has been linked to the regulation of cell growth and proliferation, but the cellular and molecular basis for these functions are not fully understood. In this study, we show that both the RII receptor Punt (Put) and the R-Smad ...
Narrowed intervertebral disc (IVD) space is a characteristic of IVD degeneration. EP sclerosis is associated with IVD, however the pathogenesis of EP hypertrophy is poorly understood. Here, we employed two spine instability mouse models to investigate temporal and spatial EP changes associated with IVD volume, considering them as a functional unit. We found that aberrant mechanical loading lead...
Regulatory T cells (Treg) that express the transcription factor Foxp3 are enriched within a broad range of murine and human solid tumors. The ontogeny of these Foxp3 Tregs - selective accumulation or proliferation of natural thymus-derived Treg (nTreg) or induced Treg (iTreg) converted in the periphery from naïve T cells - is not known. We used several strains of mice in which Foxp3 and EGFP ar...
Increased serum concentrations of tumor necrosis factor α (TNFα) and transforming growth factor β-1 (TGFβ-1) in the blood of patients with pancreatic cancer (PC) have previously been demonstrated. In addition, exogenous exposure to these cytokines promotes various cancer cell invasive and cancer stem cell (CSC) phenotypes. However, their importance in pancreatic CSCs remains elusive. In the pre...
BACKGROUND Previous studies demonstrated that puerarin has therapeutic effects on cardiac hypertrophy. This study aimed to explore whether the effect of puerarin on attenuating cardiac hypertrophy is related to regulation of microRNAs (miRNAs) and the transforming growth factor beta (TGFβ) signal pathway. MATERIAL AND METHODS The therapeutic effect of puerarin was assessed using an angiotensin ...
BACKGROUND During scleroderma (SSc) pathogenesis, fibroblasts acquire an activated phenotype characterized by enhanced production of extracellular matrix (ECM) and constitutive activation of several major signaling pathways including extracellular signal-related kinase (ERK1/2). Several studies have addressed the role of ERK1/2 in SSc fibrosis however the mechanism of its prolonged activation i...
objective: studies reported conflicting results’ regarding the status of depression and glycemic control in patients with type ii diabetes(t2dm), therefore, this study was performed to determine the relationship between depression and glycemic control in t2dm patients. materials and methods: this cross-sectional study was performed on 150 t2dm patients referred to yazd diabetes research center,...
tyrosinemia type ii is a rare autosomal recessive disorder wich can present itself with recurrent epithelial keratitis, hyperkeratotic skin lesions and mental retardation. this article reports the rare occurrence of this disease in both offsprings (two brothers) of a family (consanguinous'marriage) who were managed with a lowprotein diet and a special regimen.
