Oral submucous fibrosis (OSF) is a precancerous condition with symptoms of limited mouth opening and areca nut chewing habit has been implicated in its pathogenesis. Hinokitiol, a natural tropolone derived from Chamacyparis taiwanensis, has been reported to improve oral lichen planus and inhibit various cancer cells. Here, we showed that hinokitiol reduced the myofibroblast activities in fBMFs and prevented the arecoline-induced transdifferentiation. Treatment of hinokitiol dose-dependently downregulated the myofibroblast markers as well as various EMT transcriptional factors...

Chronic pancreatitis/pancreatic cancer (CP/PC) is characterized by fibrous connective tissue proliferation induced by activated pancreatic stellate cells (PSCs). Galectin-1 is upregulated in activated PSCs and is important for the continuing activation of PSCs. The aim of this study was to evaluate the effect of galectin-1 derived from activated PSCs on the progression of fibrosis in CP/PC. To this end, the expression of desmin, α-SMA, galectin-1, fibronectin and collagen type I in normal pancreatic, CP and PC tissues, as well as quiescent/activated PSCs, was investigated...

OBJECTIVE: Liver fibrosis is a global health problem that causes approximately 1.4 million deaths per year. It is associated with inflammation, oxidative stress, necrosis and ends with cirrhosis, liver cancer, or liver failure. Therefore, the present study was constructed to investigate the protective effect of resveratrol (RVT) on liver fibrosis, focusing on the possible involvement of alpha 1-fetoprotein and protein kinase C signaling. MATERIALS AND METHODS: Rats received thioacetamide (TAA) (200 mg/kg, intraperitoneal) twice weekly, for 4 successive weeks to induce liver fibrosis...

We aimed to determine whether aflatoxin dietary exposure plays a role in the high incidence of hepatocellular carcinoma (HCC) observed among Hispanics in South Texas. We measured TP53R249S somatic mutation, hallmark of aflatoxin etiology in HCC, using droplet digital PCR and RFLP. TP53R249S mutation was detected in 3 of 41 HCC tumors from Hispanics in South Texas (7.3%). We also measured TP53R249S mutation in plasma cell-free DNA (cfDNA) from 218 HCC patients and 96 Hispanic subjects with advanced fibrosis or cirrhosis, from South Texas...

The extracellular matrix protein collagen VII is part of the microenvironment of stratified epithelia and critical in organismal homeostasis. Mutations in the encoding gene COL7A1 lead to the skin disorder dystrophic epidermolysis bullosa (DEB), are linked to skin fragility and progressive inflammation-driven fibrosis that facilitates aggressive skin cancer. So far, these changes have been linked to mesenchymal alterations, the epithelial consequences of collagen VII loss remaining under-addressed. As epithelial dysfunction is a principal initiator of fibrosis, we performed a comprehensive transcriptome and proteome profiling of primary human keratinocytes to generate global and detailed images of dysregulated epidermal molecular pathways linked to loss of collagen VII...

Retinoic acid (RA) plays a pivotal role in many cellular processes; however, the signaling mechanisms mediating the effect of RA are not fully understood. Here, we show that RA transcriptionally upregulates cystic fibrosis transmembrane conductance regulator (Cftr) by promoting the direct binding of its receptor RARα to Cftr promoter in mouse spermatogonia and embryonic stem (ES) cells. The RA/CFTR pathway is involved in the differentiation of spermatogonia and organogenesis during the embryo development of Xenopus laevis...

BACKGROUND: Epidural fibrosis is a challenging topic in spinal surgery. This phenomenon constitutes one of the the main reasons behind "post-laminectomy syndrome" or "failed-back surgery syndrome", which leads to persistent back and leg pain in association with compression and/or stretching the nerve root or the dura. The exact mechanism of action in epidural fibrosis is complex and remains uncertain. Excessive deposition of collagen, fibronectin, and dermatan sulfate known as "extracellular matrix", and decrease of tissue cellularity results in epidural fibrosis...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a disease with a worse prognosis than some types of cancer. In patients with IPF, lung cancer is critical because of the associated high mortality rate from its progression and fatal complications from anticancer treatments. Therefore, preventing lung cancer in patients with IPF is primordial. Pirfenidone is an anti-fibrotic agent that reduces the decline in forced vital capacity. This study aimed to assess the effect of pirfenidone in the development of lung cancer in patients with IPF...

Background Genetic alterations cause hereditary diseases (HDs) with a wide range of incidences. Some, like cystic fibrosi, occur frequently (1/1,000 newborns), whilst others, such as Pompe disease and other metabolic disorders are very rare (1/100,000 newborns). They are well under the threshold of 1/3,000, denoted by the European Community as rare diseases (RDs). Genetic alterations are also associated with multifactorial disorders like diabetes, and underline both somatic and germline mutations in cancer...

Every year, millions of cancer patients undergo radiation therapy for treating and destroying abnormal cell growths within normal cell environmental conditions. Thus, ionizing radiation can have positive therapeutic effects on cancer cells as well as post-detrimental effects on surrounding normal tissues. Previous studies in the past years have proposed that the reduction and oxidation metabolism in cells changes in response to ionizing radiation and has a key role in radiation toxicity to normal tissue. Free radicals generated from ionizing radiation result in upregulation of cyclooxygenases (COXs), nitric oxide synthase (NOSs), lipoxygenases (LOXs) as well as nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase), and their effected changes in mitochondrial functions are markedly noticeable...

In 2015, more than 13 000 people died due to the consequences of liver cirrhosis in Germany. Frequently, relevant liver fibrosis is diagnosed by non-invasive methods (e. g., ultrasound-based measurement of liver stiffness) already in the compensated stage. Following diagnosis of liver fibrosis, a thorough investigation of the underlying chronic liver disease and effective treatment are important to prevent progression to decompensated cirrhosis. Since morbidity and mortality dramatically increase in the decompensated stage (patients may present with jaundice, ascites, hepatic encephalopathy, gastrointestinal bleeding) with an upsurge in 1-year-mortality from 1 - 3...

BACKGROUND: Chronic HBV plays an important role in hepatocellular carcinoma pathogenesis. Previously, most studies have been focusing on HBV DNA levels before the primary curative hepatectomy. However, the association of virus level before repeat hepatectomy with the degrees of inflammation and fibrosis on histopathology and prognosis has not been surveyed. METHODS: From January 2002 to December 2009, all patients who were seropositive for hepatitis B surface antigen (HBsAg) were enrolled and assigned into four groups based on their HBV DNA levels before the primary and repeat hepatectomies...

Lung transplantation is a definitive treatment for select patients with end-stage pulmonary disease. Following transplantation, the reported rate of lung cancer is between 1-9% and is associated with a variety of risk factors, including smoking history and chronic immunosuppression. The majority of post-transplant lung cancer reported in the literature is histologically classified as non-small cell lung carcinoma (NSCLC). We report a unique case of early stage small cell lung carcinoma (SCLC) identified in the native lung following single lung transplantation...

Background: The characteristic and outcomes of lung cancer patients with combined pulmonary fibrosis and emphysema (CPFE) have long been assessed, but results were controversial. Therefore, we performed a meta-analysis to assess the clinical features and prognosis of lung cancer patients with CPFE. Methods: The databases PubMed, Embase, and Web of Science (updated to October 1, 2017) were searched for eligible studies. Pooled odds ratios (ORs), weighted mean differences (WMD) or hazard ratios (HRs) with 95% confidence intervals (95% CIs) were used to evaluate the clinicopathological characteristics, the short-term outcome after operation and long-term survival of lung cancer patients with CPFE compared with lung cancer patients without CPFE (fibrosis, emphysema, and normal)...
