This study aimed to investigate the role of src-homology protein tyrosine phosphatase-1 (SHP-1)-signal transducer and activator of transcription 3 (STAT3) pathway in liver fibrogenesis and the anti-fibrotic effect of SHP-1 agonist. The antifibrotic activity of SC-43, a sorafenib derivative with an enhanced SHP-1 activity, was evaluated in two fibrosis mouse models by carbon tetrachloride induction and bile duct ligation. Rat, human, and primary mouse hepatic stellate cells (HSCs) were used for mechanistic investigations...

Fibrosis is a potentially debilitating disease with high morbidity rates. It is estimated that half of all deaths that occur in the USA are attributed to fibrotic disorders. Fibrotic disorders are characterized primarily by disruption in the extracellular matrix deposition and breakdown equilibrium, leading to the accumulation of excessive amounts of extracellular matrix. Given the potentially high prevalence of fibrosis and the paucity of agents currently available for the treatment of this disease, there is an urgent need for the identification of drugs that can be utilized to treat the disease...

Arsenic trioxide (As2O3) is utilized for treating patients suffering from hematological malignancies particularly acute promyelocytic leukemia. Unfortunately, the extensive application of this chemotherapeutic agent has been limited due to its adverse effects such as cardiotoxicity. Ellagic acid, as a phenolic compound, has shown to exert antioxidant, anti-inflammatory, antifibrotic, and antiatherogenic properties. It is also capable of protecting against drug toxicity. In this study, we evaluated whether ellagic acid can protect against As2O3-induced heart injury in rats...

Numerous compounds have shown efficacy in limiting development of pulmonary fibrosis using animal models, yet few of these compounds have replicated these beneficial effects in clinical trials. Given the challenges associated with performing clinical trials in patients with idiopathic pulmonary fibrosis (IPF), it is imperative that preclinical data packages be robust in their analyses and interpretations to have the best chance of selecting promising drug candidates to advance to clinical trials. The American Thoracic Society has convened a group of experts in lung fibrosis to discuss and formalize recommendations for preclinical assessment of antifibrotic compounds...

Transmembrane 4 L six family member 5 (TM4SF5) can form tetraspanin-enriched microdomains (TERMs) on the cell's surface. TERMs contain protein-protein complexes comprised of tetraspanins, growth factor receptors, and integrins. These complexes regulate communication between extracellular and intracellular spaces to control diverse cellular functions. TM4SF5 influences the epithelial-mesenchymal transition (EMT), aberrant multilayer cellular growth, drug resistance, enhanced migration and invasion, circulation through the bloodstream, tumor-initiation property, metastasis, and muscle development in zebrafish...

Pulmonary fibrosis is associated with a number of specific forms of interstitial lung disease (ILD) and can lead to progressive decline in lung function, poor quality of life, and, ultimately, early death. Idiopathic pulmonary fibrosis (IPF), the most common fibrotic ILD, affects up to 1 in 200 elderly individuals and has a median survival that ranges from 3 to 5 years following initial diagnosis. IPF has not been shown to respond to immunomodulatory therapies, but recent trials with novel antifibrotic agents have demonstrated lessening of lung function decline over time...

Liver fibrosis is a pathological process complicating schistosomiasis. It is an active process of continuous extracellular matrix accumulation. In Egypt, schistosomiasis re-infection is a continuing problem especially in rural areas. In this study we examined the antifibrotic effect of GDC-0449 (Vismodegib), a hedgehog-pathway inhibitor as a new molecular target for Schistosoma-induced liver fibrosis, in addition to exploring its effect as antischistosomal drug. The effect of GDC-0449 alone or combined with Praziquantel was tried experimentally in infected mice with Schistosoma mansoni...

BACKGROUND: Gastroesophageal reflux disease is a potential risk factor for idiopathic pulmonary fibrosis (IPF) progression; however, the impact of antacid therapy (AAT) is under debate. OBJECTIVE: To evaluate the effect of AAT on IPF progression in pirfenidone-treated patients. METHODS: This post hoc analysis included patients with IPF who received pirfenidone in 3 trials (CAPACITY [PIPF-004/PIPF-006] and ASCEND [PIPF-016]). Pulmonary function, exercise tolerance, survival, hospitalizations, and adverse events (AEs) over 52 weeks were analyzed by baseline AAT use...

PURPOSE OF REVIEW: Nonalcoholic steatohepatitis (NASH), the aggressive form of nonalcoholic fatty liver disease (NAFLD), can progress to cirrhosis and hepatocellular cancer in 5-15% of patients and is rapidly becoming the leading cause for end-stage liver disease. Dietary caloric restriction and exercise, currently the cornerstone of therapy for NAFLD, can be difficult to achieve and maintain, underscoring the dire need for pharmacotherapy. This review presents the agents currently used in managing NAFLD and their pharmacologic targets...

Idiopathic pulmonary fibrosis (IPF) is a severe progressive and irreversible lung disease. Novel antifibrotic drugs that slow disease progression are now available. However, many issues regarding patient management remain unanswered, such as the choice between available drugs, their use in particular subgroups and clinical situations, time of treatment onset, termination, combination or switch, or nonpharmacologic management. To guide Swiss respiratory physicians in this evolving field still characterized by numerous areas of uncertainty, the Swiss Working Group for interstitial and rare lung diseases of the Swiss Respiratory Society provides a position paper on the diagnosis and treatment of IPF...

Chronic alcohol consumption leads to extracellular matrix hyperplasia and liver fibrosis with a great role of hepatic stellate cell (HSC) activation in this process. The present study was designed to investigate the possible protective effects of diethylcarbamazine (DEC) (50mg/kg, acting as an anti-inflammatory drug, interferes with the arachidonic acid metabolism) when administrated in combination with hesperidin (HDN) (200mg/kg, a flavanone glycoside with potent antioxidant and anti-inflammatory activities) against alcoholic liver fibrosis in wistar rats compared to silymarin (Sil) (100mg/kg)...

Non-alcoholic steatohepatitis (NASH) is characterized by steatosis with lobular inflammation and hepatocyte injury. Pirfenidone (PFD) is an orally bioavailable pyridone derivative that has been clinically used for the treatment of idiopathic pulmonary fibrosis. However, it remains unknown whether PFD improves liver fibrosis in a mouse model with human NASH-like phenotypes. In this study, we employed melanocortin 4 receptor-deficient (MC4R-KO) mice as a mouse model with human NASH-like phenotypes to elucidate the effect and action mechanisms of PFD on the development of NASH...

Current treatment modalities are not effective in halting the progression of most CKD. Renal fibrosis is a pathological process common to all CKD and thereby represents an excellent treatment target. A large number of molecular pathways involved in renal fibrosis were identified in preclinical studies, some of them being similar among different organs and some with available drugs in various phases of clinical testing. Yet only few clinical trials with antifibrotic drugs are being conducted in CKD patients...

RATIONALE: Idiopathic pulmonary fibrosis (IPF) is characterized by excessive deposition of extracellular matrix, in particular collagens. Two IPF therapeutics, nintedanib and pirfenidone, decelerate lung function decline, but their underlying mechanisms of action are poorly understood. In this study we sought to analyze their effects on collagen synthesis and maturation at important regulatory levels. METHODS: Primary human fibroblasts from IPF patients and healthy donors were treated with nintedanib (0...

Proton pump inhibitors (PPIs) are well-known antacid drugs developed to treat gastric disorders. Emerging studies demonstrate that PPIs possess biological activities that extend beyond inhibition of H(+)/K(+) ATPase (proton pumps) expressed in parietal cells of the stomach. Some of the extra-gastric activities of PPIs include modulation of epithelial, endothelial, and immune cell functions. Recently, we reported that PPIs suppress the expression of several proinflammatory and profibrotic molecules, as well as enhance antioxidant mechanisms in order to favorably regulate lung inflammation and fibrosis in an animal model of bleomycin-induced lung injury...

In 2004, the first nonpeptide selective angiotensin II type 2 receptor (AT2R) agonist was reported. This nonpeptide (C21), which, exerts anti-inflammatory and antifibrotic actions in vivo, has been extensively explored and is currently in clinical trials. Subsequently, a large number of related drug-like AT2R agonists have been disclosed. Reviews that summarize known structure-activity relationships (SAR) of nonpeptide AT2R agonists have recently appeared in the literature; however, very few reviews discuss the role of angiotensin peptides as AT2R agonists...

Pirfenidone is an antifibrotic drug, recently approved for the treatment of patients suffering from idiopathic pulmonary fibrosis (IPF). Although pirfenidone exhibits anti-inflammatory, antioxidant, and antifibrotic properties, the molecular mechanism underlying its protective effects remains unknown. Here, we link pirfenidone action with the regulation of the profibrotic hedgehog (Hh) signaling pathway. We demonstrate that pirfenidone selectively destabilizes the glioma-associated oncogene homolog (GLI)2 protein, the primary activator of Hh-mediated gene transcription...

Idiopathic pulmonary fibrosis (IPF) is a fatal progressive fibrotic lung disease characterized by the presence of invasive myofibroblasts in the lung. Currently, there are only two FDA-approved drugs (pirfenidone and nintedanib) for the treatment of IPF. There are no defined criteria to guide specific drug therapy. New methodologies are needed not only to predict personalized drug therapy, but also to screen novel molecules that are on the horizon for treatment of IPF. We have developed a model system that exploits the invasive phenotype of IPF lung tissue...

Idiopathic pulmonary fibrosis (IPF) is a devastating, progressive and ultimately fatal lung disease. The combination of poor prognosis, uncertainty of disease course and severe symptom burden heavily impacts patients' and their families' quality of life. Though new antifibrotic drugs have been shown to decrease disease progression, the effect on health-related quality of life (HRQOL) has not been convincingly demonstrated. In a relentless disease such as IPF, striving to optimize HRQOL should complement the endeavour to prolong life...
