Abstract
The pathogenesis of idiopathic inflammatory myositis (IIMs, including polymyositis and dermatomyositis) remains largely enigmatic, despite advances in the study of the role played by innate immunity, adaptive immunity, genetic predisposition, and environmental factors in an orchestrated response. Several factors are involved in the inflammatory state that characterizes the different forms of IIMs which share features and mechanisms but are clearly different with respect to the involved sites and characteristics of the inflammation. Cellular and non-cellular mechanisms of both the immune and non-immune systems have been identified as key regulators of inflammation in polymyositis/dermatomyositis, particularly at different stages of disease, leading to the fibrotic state that characterizes the end stage. Among these, a special role is played by an interferon signature and complement cascade with different mechanisms in polymyositis and dermatomyositis; these differences can be identified also histologically in muscle biopsies. Numerous cellular components of the adaptive and innate immune response are present in the site of tissue inflammation, and the complexity of idiopathic inflammatory myositis is further supported by the involvement of non-immune mechanisms such as hypoxia and autophagy. The aim of this comprehensive review is to describe the major pathogenic mechanisms involved in the onset of idiopathic inflammatory myositis and to report on the major working hypothesis with therapeutic implications.

A functional polymorphism C-509T in TGFβ-1 promoter contributes to susceptibility and prognosis of lone atrial fibrillation in Chinese population. PLoS One 2014; 9:e112912. [PMID: 25402477 PMCID: PMC4234495 DOI: 10.1371/journal.pone.0112912] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2014] [Accepted: 10/16/2014] [Indexed: 11/18/2022] Open
Abstract
Transforming growth factor-β1 (TGF-β1) is an important mediator of atrial fibrosis and atrial fibrillation (AF). But the involved genetic mechanism is unknown. Herein, the TGF-β1 C-509 T polymorphism (rs1800469) was genotyped in a case-control study of 840 patients and 845 controls in Chinese population to explore the association between the polymorphism and susceptibility and prognosis of lone AF. As a result, the CT and/or TT genotypes had an increased lone AF risk [adjusted odds ratio (OR) = 1.50 for CT, OR = 3.72 for TT, and OR = 2.15 for CT/TT], compared with the TGF-β1CC genotype. Moreover, patients carrying CT/TT genotypes showed a higher possibility of AF recurrence after catheter ablation, compared with patients carrying CC genotype. In a genotype-phenotype correlation analysis using 24 normal left atrial appendage samples, increasing gradients of atrial TGF-β1 expression levels positively correlated with atrial collagen volume fraction were identified in samples with CC, CT and TT genotypes. The in vitro luciferase assays also showed a higher luciferase activity of the -509 T allele than that of the -509 C allele. In conclusion, the TGF-β1 C-509 T polymorphism is involved in the etiology of lone AF and thus may be a marker for genetic susceptibility to lone AF and predicting prognosis after catheter ablation in Chinese populations. Therefore, we provide new information about treatment strategies and our understanding of TGF-β1 in AF.

[PMID: 24124327 PMCID: PMC3792337 DOI: 10.3748/wjg.v19.i35.5828] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2013] [Revised: 05/30/2013] [Accepted: 07/11/2013] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate whether transforming growth factor-β1 (TGF-β1) signaling pathway is involved in the pathogenesis of primary biliary cirrhosis (PBC).
METHODS: A murine model of PBC was developed by injection of polyinosinic polycytidylic acids (poly I: C) in C57BL/6 mice, and the liver expressions of TGF β1, TGF-β receptor I (TβRI), TGF-β receptor II (TβRII), p-Smad2/3, monoclonal α-smooth muscle actin antibody (α-SMA) and α1 (I) collagen in the mouse model and control mice were evaluated by immunohistochemistry, immunoblotting and real-time polymerase chain reaction (RT-PCR). Lymphocyte subsets in liver were analyzed using flow cytometry.
RESULTS: The mouse model had several key phenotypic features of human PBC, including elevated levels of alkaline phosphatase, antimitochondrial antibodies, portal bile ducts inflammation, and progressive collagen deposition. Compared with control mice, protein and mRNA levels of TGF β1, TβRI, TβRII, p-Smad2/3, α-SMA and α1 (I) collagen in liver (1.7 ± 0.4 vs 8.9 ± 1.8, 0.8 ± 0.2 vs 5.1 ± 1.5, 0.6 ± 0.01 vs 5.1 ± 0.1, 0.6 ± 0.3 vs 2.0 ± 0.3, 0.9 ± 0.4 vs 3.4 ± 0.6, 0.8 ± 0.4 vs 1.7 ± 0.3, 1.1 ± 1.2 vs 11.8 ± 0.6, P < 0.05), and the total number and percentage of CD4+ CD25+ FOXP3+ and CD8+ lymphocytes (0.01 ± 0.001 vs 0.004 ± 0.00, 0.12 ± 0.04 vs 0.52 ± 0.23, P < 0.01) were higher in the mouse model.
CONCLUSION: TGFβ1 might play a dual role in the development of PBC: it suppresses inflammatory response but operates to enhance fibrogenesis. The aberrant activity of TGF-β1 signaling contributes to the development of PBC.

Abstract
Fibrosis is a pathological scarring process that leads to destruction of organ architecture and impairment of organ function. Chronic loss of organ function in most organs, including bone marrow, heart, intestine, kidney, liver, lung, and skin, is associated with fibrosis, contributing to an estimated one third of natural deaths worldwide. Effective therapies to prevent or to even reverse existing fibrotic lesions are not yet available in any organ. There is hope that an understanding of common fibrosis pathways will lead to development of antifibrotic therapies that are effective in all of these tissues in the future. Here we review common and organ-specific pathways of tissue fibrosis.

Abstract
Transforming growth factor-β (TGF-β) protein has been supposed to be a risk factor for liver cirrhosis; however, the associations between its genes (TGF-β -509C>T and +869T>C) and liver cirrhosis remained unclear. This study was to quantitatively analyze the correlations by using a meta-analysis. Pubmed, Embase, Wanfang databases were retrieved up to November 1st, 2011. Odds ratio (OR) and 95 % confidence interval (95 %CI) were used to demonstrate the strength of association, and P < 0.05 of Z test indicated statistical significance. Combined analyses were performed by using fixed or random-effect model, depending on between-study heterogeneity. Seven studies were for TGF-β -509C>T polymorphism, and eight studies were for +869T>C polymorphism. Combined results indicated that neither TGF-β -509C>T nor +869T>C polymorphisms were associated with risk of liver cirrhosis [OR (95 % CI): 0.79 (0.60-1.04) for CT vs. TT of -509C>T and 0.87 (0.68-1.12) for CT vs. CC of +869T>C], with no between-study heterogeneity. In addition, subgroups analyses still inferred that two polymorphisms were not associated with risk of liver cirrhosis for HBV-infected patients, Asians and for Population-based studies. This meta-analysis indicated that neither TGF-β -509C>T nor +869T>C polymorphisms were associated with risk of liver cirrhosis, regardless of HBV infection or not.

Abstract
Background/Aims Transforming growth factor beta1 (TGF-β1) is a key cytokine in the production of extracellular matrix. A genetic polymorphism at codon 10 of the TGF-β1 gene is associated with liver fibrosis. We investigated the effect of genetic polymorphisms at codon 10 on the development of alcoholic liver cirrhosis (ALC). Methods In total, 119 controls and 182 patients with ALC, were enrolled in the study. Clinical and laboratory data including total lifetime alcohol intake were collected at enrollment. The genotype at codon 10 was determined for each patient by single-strand conformation polymorphism. Results There were three types of genetic polymorphism at codon 10: homozygous proline (P/P), heterozygous proline/leucine (P/L), and homozygous leucine (L/L). Among the controls, the proportions of P/P, P/L, and L/L were 26.1%, 44.5%, and 29.4%, respectively in the ALC group, these proportions were 23.1%, 43.4%, and 33.5%, respectively. The genotype distribution did not differ between the controls and the ALC group. In the ALC group, age, total lifetime alcohol intake, and distribution of Child-Pugh class did not differ with the genotype. Of the male patients with ALC (n=164), the proportions of P/P, P/L, and L/L were 20.1%, 44.5%, and 35.4%, respectively the genotype distribution did not differ between the male controls and the male ALC patients. Conclusions The genotype at codon 10 in TGF-β1 does not appear to influence the development of ALC. Further study is needed to investigate other genetic factors that influence the development of ALC in patients with chronic alcohol intake.

Abstract
AIM: To summarize the histological features of autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC) and chronic virus hepatitis of type B (CHB), and to investigate the significance of ERα and TGF-β1 expression in the above liver diseases.
METHODS: Histological examination was performed using liver biopsy specimens from 29 patients with AIH, 18 patients with PBC, and 15 patients with CHB. Immunohistochemistry was used to detect the expression of ERα and TGF-β1 in the above specimens and 8 normal liver tissue specimens.
RESULTS: The incidences of feathery degeneration, bile thrombus, and bile duct hyperplasia were significantly different among AIH, PBC, and CHB (33.33% vs 3.45%, 6.67%; 44.44% vs 6.92%, 6.67%; 61.11% vs 34.48%, 13.33%; all P < 0.05). In patients with PBC, the expression of TGF-β1 was significantly higher in the portal area than in the hepatic lobule (31.80 ± 15.92 vs 16.00 ± 6.28, P < 0.05). The expression of TGF-β1 in the portal area was significantly higher in PBC than in the other three groups (31.80 ± 15.92 vs 10.00 ± 12.15, 13.44 ± 13.51, 3.20 ± 3.20, all P < 0.01). In normal controls, the expression of TGF-β1 was significantly higher in the hepatic lobule than in the portal area (16.85 ± 3.48 vs 3.20 ± 3.20, P < 0.01). The expression of ERα was significantly different among the four groups. The expression of ERα was significantly higher in AIH and PBC than in normal controls (94.78 ± 48.36, 110.40 ± 36.66 vs 28.98 ± 24.60, both P < 0.01).
CONCLUSION: Different autoimmune liver diseases have different histological features. AIH is characterized by interface hepatitis, and PBC by destructive cholangitis. ERα and TGF-β1 may mediate and promote the development and progression of autoimmune liver diseases.

Abstract
A substantial body of evidence indicates that dysregulation of the immune system is associated with suicidal behavior in major depressive disorder (MDD). Transforming growth factor (TGF)-beta1 is believed to be an important factor in regulating inflammatory responses and to have anti-inflammatory effects. We aimed to identify the role of TGF-beta1 on suicidal depression. The TGF-beta1 polymorphisms at codons 10 and 25 were analyzed in 122 suicidal MDD patients, 61 non-suicidal MDD patients, and 120 control subjects and, among them, in vitro TGF-beta1 productions were measured in 48 suicidal MDD patients, 47 non-suicidal MDD patients, and 91 control subjects. There was no genetic polymorphism at codon 25 and three genotypes at codon 10. No significant difference in the distributions of the TGF-beta1 genotypes was found among the three groups. The in vitro TGF-beta1 productions were significantly higher in suicidal MDD patients (844.3+/-329.7 pg/ml) and in non-suicidal MDD patients (853.0+/-439.7 pg/ml) than in controls (683.0+/-397.0 pg/ml) (P=0.01). In vitro TGF-beta1 productions were not significantly different among patients with any of the TGF-beta1 alleles or genotypes. Our findings suggest that in vitro TGF-beta1 productions play an important role on MDD, but we found no associations between TGF-beta1 and suicidal behavior.

Abstract
Transforming growth factor beta (TGF-beta) superfamily signaling pathways are ubiquitous and essential regulators of cellular processes including proliferation, differentiation, migration, and survival, as well as physiological processes, including embryonic development, angiogenesis, and wound healing. Alterations in these pathways, including either germ-line or somatic mutations or alterations in the expression of members of these signaling pathways often result in human disease. Appropriate regulation of these pathways is required at all levels, particularly at the ligand level, with either a deficiency or an excess of specific TGF-beta superfamily ligands resulting in human disease. TGF-beta superfamily ligands and members of these TGF-beta superfamily signaling pathways also have emerging roles as diagnostic, prognostic or predictive markers for human disease. Ongoing studies will enable targeting of TGF-beta superfamily signaling pathways for the chemoprevention and treatment of human disease.
