Fibroblast is believed to be the primary effector in idiopathic pulmonary fibrosis (IPF), a progressive lung disorder characterized by aberrant tissue remodeling and the formation of fibroblastic foci. Due to the complicated etiology and mechanism, there are few effective drugs for this fatal disease. Shikonin (SHI), which is the major ingredient isolated from the plant Lithospermum Erythrorhizon, has long been used as traditional medicine for many diseases including inflammation and cancer. The roles of SHI in attenuating skin scar and renal fibrosis by reducing TGFβ1-stimulated fibroblast activation are also reported...

Chronic wounds affect 12-15% of patients with diabetes and are associated with a drastic decrease in their quality of life. Here we demonstrate that purified mature naïve B220(+) /CD19(+) /IgM(+) /IgD(+) B cells improve healing of acute and diabetic murine wounds after a single topical application. B cell treatment significantly accelerated acute wound closure by 2-3 days in wild-type mice and 5-6 days in obese diabetic mice. The treatment led to full closure in 43% of chronic diabetic wounds, as compared to only 5% in saline-treated controls...

Despite advanced efforts in early diagnosis, aggressive surgical treatment, and use of targeted chemotherapies, the prognosis for many cancers is still dismal. This emphasizes the necessity to develop new strategies for understanding tumor growth and metastasis. Here we use a systems approach that combines mathematical modeling and numerical simulation to develop a predictive computational model for prostate cancer and its subversion of the bone microenvironment. This model simulates metastatic prostate cancer evolution, progressing from normal bone and hormone levels to quantifiable diseased states...

BACKGROUND: We previously demonstrated that maternal exposure to di-n-butyl phthalate (DBP) induces dysplasia of the kidney in newborn male offspring and renal fibrosis in adults. But the underlying mechanisms remain elusive. Fgf10/Fgfr2 and androgen receptor (AR) are known to be important for renal development. We therefore investigated whether these genes are involved in DBP-induced renal fibrosis. MATERIALS AND METHODS: Using Sprague-Dawley rats and rat renal proximal tubular cells (NRK52E), we determined the potential involvement of Fgf10, Fgfr2 and AR in DBP-induced renal fibrosis...

In systemic sclerosis (SSc) immuno-inflammatory events are central to disease development. Amongst other mediators of inflammation, interleukin 17 (IL-17) and Th17 cells have been reported to be increased in the peripheral blood and target organs including involved skin in SSc. They participate and amplify inflammatory responses by inducing the production of cytokines such as IL-6, chemokines such as CCL2 and CXCL8 (IL-8), matrix metalloproteinases-1, -2, -9 and the expression of adhesion molecules in stromal cells including fibroblasts and endothelial cells...

Pluripotent cells emanate from the inner cell mass (ICM) of the blastocyst and when cultivated under optimal conditions immortalize as embryonic stem cells (ESCs). The fundamental mechanism underlying ESC derivation has, however, remained elusive. Recently, we have devised a highly efficient approach for establishing ESCs, through inhibition of the MEK and TGF-β pathways. This regimen provides a platform for dissecting the molecular mechanism of ESC derivation. Via temporal gene expression analysis, we reveal key genes involved in the ICM to ESC transition...

Bone-derived fibroblast growth factor 23 (FGF23) is an important endocrine regulator of mineral homeostasis with effects transduced by cognate FGF receptor (FGFR)1-α-Klotho complexes. Circulating FGF23 levels rise precipitously in patients with kidney disease and portend to worse renal and cardiovascular outcomes. De novo expression of FGF23 has been found in the heart and kidney following injury but its significance remains unclear. Studies showing that exposure to chronically high FGF23 concentrations activates hypertrophic gene programmes in the cardiomyocyte, has spawned intense interest in other pathological off-target effects of FGF23 excess...

BACKGROUND & AIMS: Development of hepatocellular carcinoma (HCC) is associated with alterations in the transforming growth factor beta (TGFβ) signaling pathway, which regulates liver inflammation and can have tumor suppressor or promoter activities. Little is known about the roles of specific members of this pathway at specific of HCC development. We took an integrated approach to identify and validate the effects of changes in this pathway in HCC and identify therapeutic targets. METHODS: We performed transcriptome analyses for a total of 488 HCCs that include data from The Cancer Genome Atlas...

Several studies have shown an imbalance between proinflammatory and anti-inflammatory cytokines in depression and anxiety disorders. However, less attention has been paid to the role of cytokines in psychological disorder in mothers who breastfeed. This study looks at whether concentration levels of TGF-β2 are altered in anxious and depressive breastfeeding mothers. This study checked the concentration level of TGF-B2 in relation with psychological symptoms on 110 breastfeeding mothers; based on random sampling method with using of Beck Depression Inventory (BDI), General Health Questionnaire (GHQ) and Spielberger Stress Scale (STAI) in 2015 also TGF-β2 was measured in breast milk using ELISA...

Accumulating evidence indicates that the exposure to Mycobacterium bovis bacillus Calmette-Guérin (BCG) prevents the development of allergy and the airway dendritic cells (DCs) may be involved in this protective effect. However, studies to better characterize the specific interactions between BCG and DCs and their role in this mycobacteria-mediated Th2 cell suppression are still ongoing. This study aimed to evaluate the effect of the neonatal BCG vaccination in the innate immune response in a mouse model of ovalbumin (OVA)-induced airway inflammation...

Bone is a highly integrative and dynamic tissue of the human body. It is continually remodeled by bone cells such as osteoblasts, osteoclasts. When a fraction of a bone is damaged or deformed, stem cells and bone cells under the influence of several signaling pathways regulate bone regeneration at the particular locale. Effective therapies for bone defects can be met via bone tissue engineering which employs drug delivery systems with biomaterials to enhance cellular functions by acting on signaling pathways such as Wnt, BMP, TGF-β, and Notch...

Although many advances have been made in understanding the pathogenesis of liver fibrosis, few options are available for treatment. Casticin, one of the major flavonoids in Fructus Viticis extracts, has shown hepatoprotective potential, but its effects on liver fibrosis are not clear. In this study, we investigated the antifibrotic activity of casticin and its underlying mechanism in vivo and in vitro. Male mice were injected intraperitoneally with carbon tetrachloride (CCl4) or underwent bile duct ligation (BDL) to induce liver fibrosis, followed by treatment with casticin or vehicle...

Because titanium alloy (Ti) has the natural advantage of a low elastic modulus, it has become the most commonly used material for the manufacturing of pedicle screws. However, its poor shear strength and osteogenic ability are undesirable properties. The superior osteoinductivity demonstrated by tantalum (Ta) in oral and maxillofacial surgery and joint surgery leads us to assume that the tantalum-coated pedicle screws may have better osteogenic properties and bone anchoring strength. To verify this hypothesis, MC3T3-E1 cells and human mesenchymal stem cells (hBMSCs) were seeded on the surface of Ta and Ti disks to compare the effects of two different metals on cell adhesion, proliferation, and differentiation...

RATIONALE: Hypoxia has long been implicated in the pathogenesis of fibrotic diseases. Aberrantly activated myofibroblasts are the primary pathological driver of fibrotic progression, yet how various microenvironmental influences such as hypoxia contribute to their sustained activation and differentiation is poorly understood. OBJECTIVES: As a defining feature of hypoxia is its impact on cellular metabolism, we sought to investigate how hypoxia-induced metabolic reprogramming affects myofibroblast differentiation and fibrotic progression, and to test the pre-clinical efficacy of targeting glycolytic metabolism for the treatment of pulmonary fibrosis...

Pneumoconiosis is caused by the accumulation of airborne dust in the lung, which stimulates a progressive inflammatory response that ultimately results in lung fibrosis and respiratory failure. It is possible that regulatory cells in the immune system could function to suppress inflammation and possibly slow or reverse disease progression. However, results in this study suggest that in pneumoconiosis patients, the regulatory T cells (Tregs) and B cells are functionally impaired. First, we found that pneumoconiosis patients presented an upregulation of CD4(+) CD25(+) T cells compared to controls, whereas the CD4(+) CD25(+) and CD4(+) CD25(hi) T cells were enriched with Th1- and Th17-like cells but not Foxp3-expressing Treg cells and evidenced by significantly higher T-bet, interferon (IFN)-γ, and interleukin (IL)-17 expression but lower Foxp3 and transforming growth factor (TGF)-β expression...
