Colonization of the #Caenorhabditis elegans gut with human enteric bacterial pathogens leads to proteostasis disruption that is rescued by butyrate
Protein conformational diseases are characterized by misfolding and toxic aggregation of metastable proteins, often culminating in neurodegeneration. Enteric bacteria influence the pathogenesis of neurodegenerative diseases; however, the complexity of the human microbiome hinders our understanding of how individual microbes influence these diseases. Disruption of host protein homeostasis, or proteostasis, affects the onset and progression of… Continue reading Colonization of the #Caenorhabditis elegans gut with human enteric bacterial pathogens leads to proteostasis disruption that is rescued by butyrate
NOX4 links metabolic regulation in #pancreatic #cancer to endoplasmic reticulum redox vulnerability and dependence on PRDX4
There is an urgent need to identify vulnerabilities in pancreatic ductal adenocarcinoma (PDAC). PDAC cells acquire metabolic changes that augment NADPH production and cytosolic redox homeostasis. Here, we show that high NADPH levels drive activity of NADPH oxidase 4 (NOX4) expressed in the endoplasmic reticulum (ER) membrane. NOX4 produces H2O2 metabolized by peroxiredoxin 4 (PRDX4)… Continue reading NOX4 links metabolic regulation in #pancreatic #cancer to endoplasmic reticulum redox vulnerability and dependence on PRDX4
#Sugar-sweetened beverage intake in adulthood and adolescence and risk of early-onset #colorectal cancer among women
Sugar-sweetened beverage (SSB) consumption had substantially increased across successive US birth cohorts until 2000, and adolescents and young adults under age 50 years have the highest consumption. However, the link between SSBs and early-onset colorectal cancer (EO-CRC) remains unexamined. Design In the Nurses’ Health Study II (1991–2015), we prospectively investigated the association of SSB intake… Continue reading #Sugar-sweetened beverage intake in adulthood and adolescence and risk of early-onset #colorectal cancer among women
Fecal #microbiota transplantation for recurrent #Clostridioides difficile infection associates with functional alterations in circulating microRNAs
The molecular mechanisms underlying successful fecal microbiota transplantation (FMT) for recurrent Clostridioides difficile infection (rCDI) remain poorly understood. The primary objective of this study was to characterize alterations in microRNAs (miRs) following FMT for rCDI. MethodsSera from two prospective multicentre randomized controlled trials were analyzed for miRNA levels using the Nanostring nCounter platform and quantitative… Continue reading Fecal #microbiota transplantation for recurrent #Clostridioides difficile infection associates with functional alterations in circulating microRNAs
Western-style #diet impedes colonization and clearance of #Citrobacter rodentium
Western-style diet (WSD), which is high in fat and low in fiber, lacks nutrients to support gut microbiota. Consequently, WSD reduces microbiota density and promotes microbiota encroachment, potentially influencing colonization resistance, immune system readiness, and thus host defense against pathogenic bacteria. Here we examined the impact of WSD on infection and colitis in response to… Continue reading Western-style #diet impedes colonization and clearance of #Citrobacter rodentium
Development and validation of a risk prediction model for high-risk #adenomas at the time of first screening #colonoscopy among screening aged Canadians
The aim of this study was to develop a risk prediction model for HRAs detected at screening colonoscopy based on readily available participant information. The cohort consisted of 3035 participants aged 50 to 74 years with no history of cancer who underwent a primary screening colonoscopy at a centralized colon cancer screening centre between 2008 and… Continue reading Development and validation of a risk prediction model for high-risk #adenomas at the time of first screening #colonoscopy among screening aged Canadians
Long-term #dietary patterns are associated with pro-inflammatory and anti-inflammatory features of the gut #microbiome
The microbiome directly affects the balance of pro-inflammatory and anti-inflammatory responses in the gut. As microbes thrive on dietary substrates, the question arises whether we can nourish an anti-inflammatory gut ecosystem. We aim to unravel interactions between diet, gut microbiota and their functional ability to induce intestinal inflammation. Design We investigated the relation between 173… Continue reading Long-term #dietary patterns are associated with pro-inflammatory and anti-inflammatory features of the gut #microbiome
Dose-response association between #adiposity and #liver cancer incidence: a prospective cohort study among non-smoking and non-alcohol drinking Chinese women
Background: Based on a population with very low prevalence of smoking and alcohol drinking, we examined the associations between overall obesity and fat distribution in middle age, obesity in early adulthood, and adult weight gain with the risk of liver cancer incidence. Methods: The associations between body mass index (BMI) at study enrollment and at… Continue reading Dose-response association between #adiposity and #liver cancer incidence: a prospective cohort study among non-smoking and non-alcohol drinking Chinese women
