Analysis of Candidate Genes in Celiac Disease: A Tool to Identify Life-Threatening Associated Genes?
2006
The authors have recently reported that celiac patients show a proinflammatory cytokine genetic profile characterized by the contemporaneous presence of both the tumour necrosis factor-alpha-308A and the interferon-gamma +874T allele-positive genotypes. The same alleles are considered risk factors for aging associated disease, whereas an anti-inflammatory cytokine genotype profile might be associated with an extended life expectancy. This paper reports data on the 1249-1250InsACAA/Non-Ins transforming growth factor (TGF)-beta2, a multifunctional anti-inflammatory cytokine, polymorphism distribution in 88 celiac disease (CD) patients, 99 age- and sex-matched controls, and 2895-year-old healt…
Polymorphisms of microRNA target genes
2016
AIM To evaluate associations between miRNA target genes IL12B, INSR, CCND1 and IL10 polymorphisms and gastric cancer (GC) in European population. METHODS Gene polymorphisms were analyzed in 508 controls and 474 GC patients from 3 tertiary centers in Germany, Lithuania and Latvia. Controls were patients from the out-patient departments, who were referred for upper endoscopy because of dyspeptic symptoms and had no history of previous malignancy. Gastric cancer (GC) patients had histopathological verification of gastric adenocarcinoma. Genomic DNA was extracted using salting out method from peripheral blood mononuclear cells. IL12B T>G (rs1368439), INSR T>C (rs1051690), CCND1 A>C (rs7177) and…
Detection of HIV type 1 non-B subtypes in Sicily, Italy.
2004
To evaluate the presence of HIV-1 non-B subtypes in Sicily, we sequenced and genotyped HIV-1 PR and RT regions of the pol gene using plasma from 169 HIV-1-infected adult patients. All samples were obtained from a study of antiretroviral-associated resistance mutations resulting in virological failure during highly active antiretroviral therapy (HAART). Eight (4.7%) patients had the non-B HIV-1 subtype including some circulating recombinant forms (CRFs). All of these individuals acquired the infection by heterosexual transmission. The detection of HIV-1 non-B strains was significantly associated with younger age of HIV-1 acquisition. Our findings indicate, for the first time, the presence of…
Analysis of thiamine transporter genes in sporadic beriberi
2014
Abstract Objective Thiamine or vitamin B 1 deficiency diminishes thiamine-dependent enzymatic activity, alters mitochondrial function, impairs oxidative metabolism, and causes selective neuronal death. We analyzed for the first time, the role of all known mutations within three specific thiamine carrier genes, SLC19 A2, SLC19 A3 , and SLC25 A19 , in a patient with atrophic beriberi, a multiorgan nutritional disease caused by thiamine deficiency. Methods A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema, a subacute sensorimotor neuropathy, and incontinence. Despite normal vitamin B 1 serum levels, his clinical picture was rapidly reverted by high-dose in…
Long-term outcome prediction by clinicopathological risk classification algorithms in node-negative breast cancer--comparison between Adjuvant!, St G…
2009
Background: Defining risk categories in breast cancer is of considerable clinical significance. We have developed a novel risk classification algorithm and compared its prognostic utility to the Web-based tool Adjuvant! and to the St Gallen risk classification. Patients and methods: After a median follow-up of 10 years, we retrospectively analyzed 410 consecutive node-negative breast cancer patients who had not received adjuvant systemic therapy. High risk was defined by any of the following criteria: (i) age 2 cm. All patients were also characterized using Adjuvant! and the St Gallen 2007 risk categories. We analyzed disease-free survival (DFS) and overall survival (OS). Results: The Node-…
A membrane computing simulator of trans-hierarchical antibiotic resistance evolution dynamics in nested ecological compartments (ARES)
2015
In this article, we introduce ARES (Antibiotic Resistance Evolution Simulator) a software device that simulates P-system model scenarios with five types of nested computing membranes oriented to emulate a hierarchy of eco-biological compartments, i.e. a) peripheral ecosystem; b) local environment; c) reservoir of supplies; d) animal host; and e) host's associated bacterial organisms (microbiome). Computational objects emulating molecular entities such as plasmids, antibiotic resistance genes, antimicrobials, and/or other substances can be introduced into this framework and may interact and evolve together with the membranes, according to a set of pre-established rules and specifications. AR…
TP53 codon 72 polymorphism and cervical cancer
2009
Background Cervical cancer is caused primarily by human papillomaviruses (HPV). The polymorphism rs1042522 at codon 72 of the TP53 tumour-suppressor gene has been investigated as a genetic cofactor. More than 80 studies were done between 1998 and 2006, after it was initially reported that women who are homozygous for the arginine allele had a risk for cervical cancer seven times higher than women who were heterozygous for the allele. However, results have been inconsistent. Here we analyse pooled data from 49 studies to determine whether there is an association between TP53 codon 72 polymorphism and cervical cancer.Methods Individual data on 7946 cases and 7888 controls from 49 different st…
Inflammation, genes and zinc in Alzheimer's disease.
2007
Alzheimer's disease (AD) is a heterogeneous and progressive neurodegenerative disease which in Western society mainly accounts for clinical dementia. AD has been linked to inflammation and metal biological pathway. Neuro-pathological hallmarks are senile plaques, resulting from the accumulation of several proteins and an inflammatory reaction around deposits of amyloid, a fibrillar protein, Abeta, product of cleavage of a much larger protein, the beta-amyloid precursor protein (APP) and neurofibrillary tangles. Amyloid deposition, due to the accumulation of Abeta peptide, is the main pathogenetic mechanism. Inflammation clearly occurs in pathologically vulnerable regions of AD and several i…
Disentangling the rhizosphere effect on nitrate reducers and denitrifiers: insight into the role of root exudates.
2008
International audience; To determine to which extent root-derived carbon contributes to the effects of plants on nitrate reducers and denitrifiers, four solutions containing different proportions of sugar, organic acids and amino acids mimicking maize root exudates were added daily to soil microcosms at a concentration of 150 μg C g−1 of soil. Water-amended soils were used as controls. After 1 month, the size and structure of the nitrate reducer and denitrifier communities were analysed using the narG and napA, and the nirK, nirS and nosZ genes as molecular markers respectively. Addition of artificial root exudates (ARE) did not strongly affect the structure or the density of nitrate reduce…
Response of the PCB-contaminated soil bacterial community to applied bioremediation treatments
2011
For full field implementation of the bioremediation as a strategy for cleaning PCB-contaminated soils, the impact of the applied treatment on the microbial community needs to be clarified. An ideal bioremediation should have positive effects on PCB-removal but should pose no treats to the health of the soil ecosystem. Microbes, playing an essential role in maintenance of the soil ecosystem, are the first indicators of a negative impact of soil manipulation to ecosystem. A small-scale bioremediation experiment was conducted in order to get insight into behavior of the microbial community during bioremediation of PCB-contaminated soil, targeting both functional PCB-degrading community (by bph…
