INTRODUCTION: Aspirin-exacerbated respiratory disease (AERD) refers to the combination of asthma rhinosinusitis and poliposis; ingestion of aspirin or other non-steroid anti-inflammatory drugs exacerbate asthma-like symptoms. The pathogenesis of AERD is unknown, and genetic and environmental factors contribute to the disease. Our objective is identifying polymorphisms associated with susceptibility in a Mexican mestizo population. METHODS: Primarily we performed custom Illumina goldengate array-based genotyping of 1512 SNPs, carefully selected from a variety of acute/chronic inflammatory lung conditions previously reported...

HNPCC is an autosomal inherited cancer syndrome characterized by germinal and somatic mutations of DNA mismatch repair (MMR) genes. The inherited mutation in one allele together with an acquired defect in the other allele of an MMR gene leads to accelerate tumor progression. In this study we analyzed a cohort of 11 subjects belonging to four Sicilian families with HNPCC suspected by molecular analysis of coding regions of hMSH2 (NC_000002) and hMLH1 (NC_000003) genes. Molecular analysis has detected the presence of two mutations in gene MSH2 and one mutation in MHL1 gene...

AIM: No reliable biomarker for renal cell carcinoma (RCC) exists. The purpose of this study was to analyze the value of CpG island hypermethylation of cell-free (cf) circulating serum DNA in patients with RCC as a potential biomarker. PATIENTS AND METHODS: In total 35 patients with RCC and 54 healthy individuals were enrolled in this study. Cell-free DNA (cFDNA) in serum was isolated and digested with methylation-sensitive restriction enzymes (Bsh1236I, HpaII and HinP1I) to quantify the amount of methylated Adenomatosis-poliposis-coli gene (APC), Gluthation-a-transferase-protein 1 gene (GSTP1), ARF tumor suppressor protein gene (p14(ARF)), cyclin-dependent kinase inhibitor 2A (p16), Retinoid-acid-receptor-beta gene (RAR-B), RAS-association domain family-1 gene (RASSF1), Tissue inhibitor of metalloproteinase-gene (TIMP3) and Prostaglandin-endoperoxid synthase 2 (PTGS2) DNA fragments...

BACKGROUND AND AIM: Hereditary non-poliposis colorectal cancers exhibit a high rate of microsatellite instability. Comparative studies involving stage and other prognostic parameters demonstrate a better prognosis in the presence of microsatellite instability versus colon cancers without microsatellite instability. METHODS: Our study included 608 cases diagnosed with colorectal adenocarcinoma by our laboratory between 2004-2010. The cases were re-evaluated with respect to criteria defined for MSI, taking into consideration age, anatomic localization, and histopathological criteria...

Gardner's syndrome, an autosomal dominant syndrome, is linked to familial adenomatosis polyposis (FAP), which is known mainly as a colorectal disease. FAP also presents extracolonically as intestinal polyposis, multiple osteomas, cutaneous cysts, or fibromas. This article reports the case of a 66-year-old white woman who was referred to the Oral Medicine Clinic, School of Dentistry, Universidade Vale do Rio Verde, Brazil, for evaluation of multiple sclerotic, asymptomatic masses in the jaws that were observed in a routine periapical radiographic exam by a dentist...

RATIONALE: Pulmonary hypertension (PH) is characterized by progressive elevation in pulmonary pressure and loss of small pulmonary arteries. As bone morphogenetic proteins promote pulmonary angiogenesis by recruiting the Wnt/β-catenin pathway, we proposed that β-catenin activation could reduce loss and induce regeneration of small pulmonary arteries (PAs) and attenuate PH. OBJECTIVE: This study aims to establish the role of β-catenin in protecting the pulmonary endothelium and stimulating compensatory angiogenesis after injury...

Wnt/beta-catenin signaling has been implicated in taste papilla development; however, its role in epithelial maintenance and tumor progression in the adult tongue remains elusive. We show Wnt/beta-catenin pathway activation in reporter mice and by nuclear beta-catenin staining in the epithelium and taste papilla of adult mouse and human tongues. beta-Catenin activation in APC(min/+) mice, which carry a mutation in adenomatous poliposis coli (APC), up-regulates Sonic hedgehog (Shh) and Jagged-2 (JAG2) in the tongue epithelium without formation of squamous cell carcinoma (SCC)...

BACKGROUND: Growth-differentiation factor (GDF)-15, a member of the TGF-beta superfamily, is potently induced in the intestine following mechanical injury, genotoxic insult and following non-steroidal anti-inflammatory drugs (NSAIDs) exposure. GDF-15 expression correlates with apoptosis in intestinal cells and has been implicated in the pathogenesis of colorectal cancer formation and the anti-tumor effects of NSAIDs. We sought to determine the effect of loss of Gdf15 on animal tumor models of hereditary colon cancer and in the NSAID-mediated prevention of heritable colorectal cancer...

Beta-catenin and Adenomatous poliposis coli (APC) have been implicated in non-ductal pancreatic cancers. As for many other organs, several recent publications show that beta-catenin and more largely the Wnt pathway appear to function at the level of pancreatic progenitors and endocrine cells during organogenesis. This raises the question of the cell type in which beta-catenin is mutated during tumor formation in acinar cell carcinomas, pancreatoblastomas and solid cystic papillary tumors of the pancreas.

A 46-year-old man presented with a lung tumor 17 years after a subtotal colectomy and 13 years after a partial duodenectomy for familial adenomatous polyposis (FAP). There had been no malignant transformation in the specimens from his colectomy and duodenectomy, and a current gastrointestinal investigation revealed no evidence of malignancy. Pathological analysis of the lung tumor demonstrated adenocarcinoma with clear cells and a papillary structure, accompanied by tiny tumorous nodules in the background lung parenchyma...

In a meaningful proportion of cases, CBAVD has been recognised as a probable consequence of cftr gene mutations. This lead to a further enlargement of the spectrum of clinical pictures due to "cftr deficiency". More recently, the identification of a polymorphism in intron 8 regulating the level of correct cftr transcription, shed new light on the genotype-fenotype correlation of cftr mutations. Unfortunately, little information is still available on the clinical manifestations of CBAVD other than infertility...
