Intratumoral accumulation of gut #microbiota facilitates CD47-based immunotherapy via STING signaling

..Using one defined anaerobic gut microbiota to track whether microbiota interact with host immunity, we observed that Bifidobacterium facilitates local anti-CD47 immunotherapy on tumor tissues through the capacity to accumulate within the tumor microenvironment. Systemic administration of Bifidobacterium leads to its accumulation within the tumor and converts the nonresponder mice into responders to anti-CD47 immunotherapy in a stimulator of interferon genes (STING)– and interferon-dependent fashion. … Continue reading Intratumoral accumulation of gut #microbiota facilitates CD47-based immunotherapy via STING signaling

CDC Colorectal Cancer Screening Test Use

Colorectal cancer (CRC) is the second leading cause of cancer death in the United States of cancers that affect both men and women. Despite strong evidence that screening for CRC reduces incidence and mortality, CRC screening prevalence is below the national target. This report describes current CRC screening prevalence by age, various demographic factors, and state.. In 2018, 68.8% of adults were up to date … Continue reading CDC Colorectal Cancer Screening Test Use

#Statin-induced GGPP depletion blocks macropinocytosis and starves cells with oncogenic defects

Our studies establish a connection between two isolated observations that 1) statins, taken by millions to lower cholesterol, have antitumor activity and 2) Ras-induced macropinocytosis is important in tumorigenesis. We discover that by depleting GGPP required for pseudopod extension and macropinocytosis, statins selectively kill cells with oncogenic defects by limiting nutrient uptake. https://bit.ly/2wT1ypw Continue reading #Statin-induced GGPP depletion blocks macropinocytosis and starves cells with oncogenic defects

#Colorectal Cancer Risk Following #Bariatric Surgery in a Nationwide Study of French Individuals With Obesity

..The mean (SD) follow-up was 6.2 (2.1) years for patients who underwent adjustable gastric banding, 5.5 (2.1) years for patients who underwent sleeve gastrectomy, and 5.7 (2.2) years for patients who underwent gastric bypass. In total, 13 052 incident colorectal cancers (1.2%) and 63 649 colorectal benign polyps were diagnosed. The rate of colorectal cancer was 0.6% in the bariatric surgery cohort and 1.3% in the cohort … Continue reading #Colorectal Cancer Risk Following #Bariatric Surgery in a Nationwide Study of French Individuals With Obesity

Similar #Breast Cancer Risk in Women Older Than 65 Years Initiating Glargine, Detemir, and NPH Insulins

To assess whether initiation of insulin glargine (glargine), compared with initiation of neutral protamine Hagedorn (NPH) or insulin detemir (detemir), was associated with an increased risk of breast cancer in women with diabetes.. Ever use of glargine was not associated with an increased risk of breast cancer compared with NPH (HR 0.97; 95% CI 0.88–1.06) or detemir (HR, 0.98; 95% CI 0.92–1.05). No increased risk … Continue reading Similar #Breast Cancer Risk in Women Older Than 65 Years Initiating Glargine, Detemir, and NPH Insulins

Prevalence, Incidence, and Risk of Cancer in Patients With #Psoriasis and Psoriatic Arthritis A Systematic Review and Meta-analysis

..There was an increased risk of several cancers, including keratinocyte cancer (RR, 2.28; 95% CI, 1.73-3.01), lymphomas (RR, 1.56; 95% CI, 1.37-1.78), lung cancer (RR, 1.26; 95% CI, 1.13-1.40), and bladder cancer (RR, 1.12; 95% CI, 1.04-1.19). No increased risk of cancer for patients with psoriasis treated with biologic agents was found (RR, 0.97; 95% CI, 0.85-1.10). Psoriatic arthritis was not associated with increased risk … Continue reading Prevalence, Incidence, and Risk of Cancer in Patients With #Psoriasis and Psoriatic Arthritis A Systematic Review and Meta-analysis

#Nut Consumption and Risk of #Cancer: A Meta-analysis of Prospective Studies

..When comparing the highest with the lowest category of nut intake, high consumption of nuts was significantly associated with decreased risk of overall cancer (RR = 0.90; 95% CI, 0.85–0.95). The protective effect of nut consumption was especially apparent against cancers from the digestive system (RR = 0.83; 95% CI, 0.77–0.89). Among different nut classes, significant association was only obtained for intake of tree nuts. … Continue reading #Nut Consumption and Risk of #Cancer: A Meta-analysis of Prospective Studies

#Curcumin and #Cancer

Curcumin, a polyphenol extracted from Curcuma longa in 1815, has gained attention from scientists worldwide for its biological activities (e.g., antioxidant, anti-inflammatory, antimicrobial, antiviral), among which its anticancer potential has been the most described and still remains under investigation. The present review focuses on the cell signaling pathways involved in cancer development and proliferation, and which are targeted by curcumin. Curcumin has been reported to … Continue reading #Curcumin and #Cancer

Electronic-#cigarette smoke induces #lung adenocarcinoma and #bladder urothelial hyperplasia in mice

Electronic-cigarettes (E-cigs) are marketed as a safe alternative to tobacco to deliver the stimulant nicotine, and their use is gaining in popularity, particularly among the younger population. We recently showed that mice exposed to short-term (12 wk) E-cig smoke (ECS) sustained extensive DNA damage in lungs, heart, and bladder mucosa and diminished DNA repair in lungs.. ..We found that mice exposed to ECS for 54 … Continue reading Electronic-#cigarette smoke induces #lung adenocarcinoma and #bladder urothelial hyperplasia in mice

Prevalence and clinical implications of #sarcopenic obesity in patients with solid tumours of the respiratory and gastrointestinal tracts: a population-based study

Emerging evidence on body composition suggests that sarcopenic obesity (obesity with depleted muscle mass) might be predictive of morbidity and mortality in non-malignant disease and also of toxicity to chemotherapy.. ..Available lumbar CT images of the obese patients were analysed for total skeletal muscle cross-sectional area; these values were also used to estimate total body fat-free mass (FFM).. ..Sarcopenic obesity was associated with poorer functional … Continue reading Prevalence and clinical implications of #sarcopenic obesity in patients with solid tumours of the respiratory and gastrointestinal tracts: a population-based study
