[Retracted] Inhibition airway remodeling and transforming growth factor‑β1/Smad signaling pathway by astragalus extract in asthmatic mice.

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that the P‑smad2 western blotting data shown in Fig. 7 were strikingly similar to data appearing in different form (namely, the bands appeared in the reverse orientation) in Fig. 4A in another article [Lv Z‑D, Na D, Liu F‑N, Du Z‑M, Sun Z, Li Z, Ma X‑Y, Wang Z‑N and Xu H‑M: Induction of gastric cancer cell adhesion through transforming growth factor‑beta1‑mediated peritoneal fibrosis.

A Review of Three Chinese Cases of Acromicric/Geleophysic Dysplasia with FBN1 Mutations.

Objective: This study aims to explore the clinical features and molecular diagnosis of FBN1-related acromelic dysplasia in Chinese patients.

Methods: The clinical and genetic features of three FBN1-related acromicric dysplasia (AD)/geleophysic dysplasia (GD) Chinese patients from two families were reviewed, and comprehensive medical evaluations were performed. Targeted next-generation sequencing was used to detect genetic mutations associated with short statures, including FBN1.

DLC-3 suppresses cellular proliferation, migration, and invasion in triple-negative breast cancer by the Wnt/β-catenin pathway.

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype. Our study investigated the functional role of DLC-3 in TNBC. The expression of DLC-3 was assessed by immunohistochemistry in TNBC to evaluate the clinicopathologic significance of DLC-3.

miR-135b promotes proliferation and metastasis by targeting APC in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype. The aim of our study was to investigate the functional role of microRNA-135b (miR-135b) in TNBC. A real-time polymerase chain reaction assay was used to quantify miR-135b expression levels in 90 paired TNBC tissue and adjacent normal tissue samples.

MiR-448-5p inhibits TGF-β1-induced epithelial-mesenchymal transition and pulmonary fibrosis by targeting Six1 in asthma.

MicroRNAs (miRNAs) are small yet versatile gene tuners that regulate a variety of cellular processes, including cell growth and proliferation. The aim of this study was to explore how miR-448-5p affects airway remodeling and transforming growth factor-β1 (TGF-β1)-stimulated epithelial-mesenchymal transition (EMT) by targeting Sine oculis homeobox homolog 1 (Six1) in asthma. Asthmatic mice models with airway remodeling were induced with ovalbumin solution.

Targeted inhibition of Six1 attenuates allergic airway inflammation and remodeling in asthmatic mice.

Asthma is an inflammatory disease of the airways, characterized by lung eosinophilia, mucus hypersecretion by goblet cells and airway hyperresponsiveness to inhaled allergens. The purpose of this study was to evaluate the effects of Six1 on airway inflammation and remodeling and the underlying mechanisms in a murine model of chronic asthma. Female BALB/c mice were randomly divided into four groups: phosphate-buffered saline control, ovalbumin (OVA)-induced asthma group, OVA+siNC and OVA+siSix1.

Silencing of Prrx1b suppresses cellular proliferation, migration, invasion and epithelial-mesenchymal transition in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a highly aggressive tumour subtype associated with poor prognosis. The mechanisms involved in TNBC progression remains largely unknown. To date, there are no effective therapeutic targets for this tumour subtype.

Lack of an association between XRCC2 R188H polymorphisms and breast cancer: an update meta-analysis involving 35,422 subjects.

Purpose: Several studies have investigated the associations between XRCC2 R188H polymorphism and the susceptibility to breast cancer, but the results have been inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed.

Methods: PubMed and China National Knowledge Infrastructure (CNKI) searches were carried out for relevant studies published before March 2015.

Down-regulation of BRMS1 by DNA hypermethylation and its association with metastatic progression in triple-negative breast cancer.

Breast cancer metastasis suppressor 1 (BRMS1) is a metastasis suppressor gene in several solid tumors. However, the expression and function of BRMS1 in triple-negative breast cancer (TNBC) have not been reported. In this study, we found that BRMS1 was down-regulation in breast cancer cell lines and primary TNBC, while decreased expression of BRMS1 mRNA was significantly associated with lymph node metastasis.

Transforming growth factor-β1 induces bronchial epithelial cells to mesenchymal transition by activating the Snail pathway and promotes airway remodeling in asthma.

Airway remodeling is characterized by airway wall thickening, subepithelial fibrosis, increased smooth muscle mass, angiogenesis and an increase in mucous glands, which may lead to a chronic and obstinate asthma with pulmonary function depression. In the present study, we observed substantially thickened lung tissue with extensive fibrosis in ovalbumin-sensitized mice, which was interrelated with transforming growth factor-β1 (TGF-β1) expression in bronchoalveolar lavage fluid. In vitro experiments further demonstrated that TGF-β1 resulted in epithelial-mesenchymal transition (EMT) in bronchial epithelial cells, which was characterized by the expected decrease in E-cadherin expression and the increase in vimentin and α-smooth muscle actin expression, as well as the associated increase in Snail expression at mRNA and protein levels.

Mesothelial cells differentiate into fibroblast-like cells under the scirrhous gastric cancer microenvironment and promote peritoneal carcinomatosis in vitro and in vivo.

Peritoneal metastases are one reason for the poor prognosis of scirrhous gastric cancer (SGC), and myofibroblast provides a favorable environment for the peritoneal dissemination of gastric cancer. The aim of this study was to determine whether myofibroblast originates from peritoneal mesothelial cells under the influence of the tumor microenvironment. Immunohistochemical studies of peritoneal biopsy specimens from patients with peritoneal lavage cytological (+) status demonstrate the expression of the epithelial markers cytokeratin in fibroblast-like cells entrapped in the stroma, suggesting that these cells stemmed from local conversion of mesothelial cells.

Astragalus extract attenuates allergic airway inflammation and inhibits nuclear factor κB expression in asthmatic mice.

Background: Astragalus membranaceus from traditional Chinese herbal medicines previously showed that it possesses a strong anti-inflammatory activity. The purpose of this study was to elucidate the effect of astragalus on allergen-induced airway inflammation and airway hyperresponsiveness and investigate its possible molecular mechanisms.

Methods: Female BALB/c mice sensitized and challenged with ovalbumin (OVA) developed airway inflammation.

Transforming growth factor-β 1 enhances the invasiveness of breast cancer cells by inducing a Smad2-dependent epithelial-to-mesenchymal transition.

Metastasis is unequivocally the most lethal aspect of breast cancer and the most prominent feature associated with disease recurrence, the molecular mechanisms whereby epithelial-to-mesenchymal transition (EMT) mediates the initiation and resolution of breast cancer metastasis remains poorly understood. Transforming growth factor-β1 (TGF-β1) is a multifunctional cytokine that is intimately involved in regulating numerous physiological processes, including cellular differentiation, homeostasis and EMT. Recent findings have implicated high levels of TGF-β1 were associated with poor outcome, whereas inhibition of TGF-β signaling reduces metastasis in breast cancer, suggesting that the chemo-therapeutic targeting of TGF-β1 or TGF-β signaling may offer new inroads in ameliorating metastatic disease in breast cancer patients.

The cytotoxic effect of TGF-β1 on mesothelial cells via apoptosis in early peritoneal carcinomatosis.

Peritoneal dissemination is one of the main causes of death in gastric cancer patients. We have previously reported that gastric cancer cells can induce peritoneal apoptosis, lead to damage of peritoneum integrity, and therefore promote peritoneal metastasis. However, the soluble factors secreted by cancer cells to trigger the damaging cascade remain unclear.

Inhibition airway remodeling and transforming growth factor-β1/Smad signaling pathway by astragalus extract in asthmatic mice.

Airway remodeling is characterized by airway wall thickening, subepithelial fibrosis, increased smooth muscle mass, angiogenesis and increased mucous glands, which can lead to a chronic and obstinate asthma with pulmonary function depression. In the present study, we investigated whether the astragalus extract inhibits airway remodeling in a mouse asthma model and observed the effects of astragalus extract on the transforming growth factor-β1 (TGF-β1)/Smad signaling pathway in ovalbumin-sensitized mice. Mice were sensitized and challenged by ovalbumin to establish a model of asthma.
