To study the effect of Jiawei Huangqi Guizhi Decoction on gastrointestinal hormones and TGF-β3 signal pathways in rats with chronic atrophic gastritis (CAG). The model was created by methylnitrosoguanidine (MNNG) comprehensive method. After successful modeling, it divided into three groups: group (MC group), frolic acid (AC modified high dose (HH middle (HM low (HL group). Gastric pathology obs...

BACKGROUND Transforming growth factor-β (TGF-β), a multifunctional growth factor, has three isoforms: TGF-β1, TGF-β2, and TGF-β3. Different isoforms of TGF-β are associated with different proliferation and differentiation states of the epidermis. Narrow band ultraviolet B (NBUVB) emits a concentrated UVB source of 311 nm. NBUVB 1,000 mJ/cm(2) induces apoptosis in approximately 50% of keratinocy...

Purpose: To investigate the effect of β3-adrenoceptors (β3-AR) up-regulation on fibrosis in cardiac fibroblast cells in rats and its potential mechanism. Methods: Cardiac fibroblast cells (CFB) were isolated and identified from rats’ hearts. The β3-ARupregulated cardiac fibroblast cells were constructed by lentiviral transfection technology. Thereafter, Ang II was used to induce fibrosis in car...

BACKGROUND The expression and localization of transforming growth factor-β (TGF-β) pathway proteins in different compartments of the lower airways of patients with stable COPD is unclear. We aimed to determine TGF-β pathway protein expression in patients with stable COPD. METHODS The expression and localization of TGF-β pathway components was measured in the bronchial mucosa and peripheral lu...

Several candidate genes were selected, based on their critical roles in the host’s response to intracellular bacteria, to study the genetic control of the chicken response to Salmonella enteritidis (SE). The candidate genes were: inducible nitric oxide synthase (INOS), tumor necrosis factor related apoptosis inducing ligand (TRAIL), transforming growth factor β2 (TGF-β2), transforming growth fa...

PURPOSE To delineate the role of Sphingolipids (SPLs) in the human cornea and their cross-talks with transforming growth factor beta (TGF-β) in order to develop novel, non-invasive therapies. METHODS Human corneal fibroblasts (HCFs) were harvested from healthy donors, stimulated with Vitamin C to promote extracellular matrix assembly, treated with exogenous sphingosine-1-phosphate (S1P) or sp...

A 3-D scaffold that simulates the microenvironment in vivo for regenerating cartilage is ideal. In this study, we combined silk fibroin and decellularized cartilage extracellular matrix by temperature gradient-guided thermal-induced phase separation to produce composite scaffolds (S/D). Resulting scaffolds had remarkable mechanical properties and biomimeticstructure, for a suitable substrate fo...

Transforming growth factor β (TGF-β) is a multifunctional cytokine recognized as an important regulator of inflammatory responses. The effect of inositol hexaphosphate (IP6), a naturally occurring phytochemical, on the mRNA expression of TGF- β1, TGF-β2, TGF-β3 and TβRI, TβRII, and TβRIII receptors stimulated with bacterial lipopolysaccharides (Escherichia coli and Salmonella typhimurium) and I...

Cellular senescence is an important in vivo mechanism that prevents the propagation of damaged cells. However, the precise mechanisms regulating senescence are not well characterized. Here, we find that ITGB3 (integrin beta 3 or β3) is regulated by the Polycomb protein CBX7. β3 expression accelerates the onset of senescence in human primary fibroblasts by activating the transforming growth fact...
