Autonomous cortisol secretion in patients with adrenal incidentalomas is associated with increased mortality, but detailed information about the risk associated with specific levels of autonomous cortisol secretion is not available. Objective:To measure the association between mortality and levels of autonomous cortisol secretion in patients with adrenal incidentalomas. Design:Retrospective cohort study. (ClinicalTrials.gov: NCT03919734) Setting:Two hospitals in… Continue reading Association Between Mortality and Levels of Autonomous #Cortisol Secretion by Adrenal #Incidentalomas

Nongenetic Determinants of Risk for Early-Onset #Colorectal Cancer
Incidence of early-onset (younger than 50 years of age) colorectal cancer (CRC) is increasing in many countries. Thus, elucidating the role of traditional CRC risk factors in early-onset CRC is a high priority. We sought to determine whether risk factors associated with late-onset CRC were also linked to early-onset CRC and whether association patterns differed by… Continue reading Nongenetic Determinants of Risk for Early-Onset #Colorectal Cancer
Indices of #Diet Quality and Risk of Lung #Cancer in the Women’s Health Initiative Observational Study
Prospective evidence on associations between diet quality indices and lung cancer risk is limited, particularly among older women. ObjectivesWe investigated associations between 4 diet quality indices [Healthy Eating Index-2015 (HEI-2015), Alternate Healthy Eating Index 2010 (AHEI-2010), alternate Mediterranean Diet (aMED), and Dietary Approaches to Stop Hypertension (DASH)] and lung cancer incidence and mortality in the… Continue reading Indices of #Diet Quality and Risk of Lung #Cancer in the Women’s Health Initiative Observational Study
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
Systems level profiling of #chemotherapy-induced stress resolution in #cancer cells reveals druggable trade-offs
Cancer therapies often fail to cure patients because a proportion of tumor cells withstand the toxic effects of chemotherapy. How surviving cancer cells recover from sublethal drug-induced stress is not known, but given that cellular resources are finite, stress resolution may come at the expense of less essential systems. Here, we studied the global cellular… Continue reading Systems level profiling of #chemotherapy-induced stress resolution in #cancer cells reveals druggable trade-offs
Therapeutic Repurposing of #Biguanides in #Cancer
Biguanides exert antitumor activities through various biochemical mechanisms involving mitochondrial complex I, AMP-activated protein kinase (AMPK), mammalian target of rapamycin (mTOR), and/or mitochondrial glycerophosphate dehydrogenase (mGPD). Biguanides selectively target subpopulations of cancer cells addicted to oxidative phosphorylation (OXPHOS). Metabolic adaptations triggered by biguanide exposure could be potential targets to improve the antitumor efficacy of biguanides.… Continue reading Therapeutic Repurposing of #Biguanides in #Cancer
#Metabolic syndrome and #gastric cancer risk: a systematic review and meta-analysis
Gastric cancer (GC) is the fifth diagnosed cancer worldwide and the third leading cause of death for cancer. Recent reports suggest that metabolic syndrome (MetS) has a role in etiology, progression or prognosis on GC. The aim of this study is to systematically review the evidence on the association between MetS and GC risk and… Continue reading #Metabolic syndrome and #gastric cancer risk: a systematic review and meta-analysis
#Smoking, #Radiation Therapy, and Contralateral #Breast Cancer Risk in Young Women
Evidence is mounting that cigarette smoking contributes to second primary contralateral breast cancer (CBC) risk. Whether radiation therapy (RT) interacts with smoking to modify this risk is unknown. In this multicenter, individually-matched case-control study, we examined the association between RT, smoking, and CBC risk. The study included 1,521 CBC cases and 2,212 controls with unilateral… Continue reading #Smoking, #Radiation Therapy, and Contralateral #Breast Cancer Risk in Young Women
