This finding challenges traditional assumptions about how GLP-1 medicines work in the liver.
Researchers have developed a blood test that can predict Crohn's disease years before symptoms appear. The test measures immune response to flagellin, a protein found on gut bacteria, which is elevated in individuals long before they develop the disease.
Researchers found that mutated cells dividing rapidly and having shorter cell cycles are more likely to develop cancer. In contrast, those with longer cycles exhibit resistance. The study suggests that interventions targeting cell cycle length could prevent cancer initiation in high-risk individuals.
A new study reveals a one-hour glucose tolerance test outperforms the traditional two-hour test in predicting future risk of diabetes, potentially transforming clinical practice. The test captures peak blood sugar levels, identifying an elevated risk of developing diabetes.
A large psychotherapy trial has demonstrated that trained nurses, midwives, and doulas can deliver effective talk therapy, significantly improving symptoms of depression and anxiety in pregnant and postpartum individuals. The study also found that online therapy is equally beneficial to in-person sessions.
A recent study found a strong association between floor swabs and COVID-19 cases and outbreaks in two Ontario hospitals. The researchers observed a 15-fold increase in patient cases for every 10-fold increase in viral matter detected on the floor.
Researchers found that transposable elements, known as LINE-1, play a critical role in regulating early human development. They help organize the DNA in the cell's nucleus and ensure embryonic cells progress normally through early stages. This discovery challenges previous views of these 'selfish DNA' elements.
Researchers at Lunenfeld-Tanenbaum Research Institute have discovered a gut-brain-immune network controlling inflammation across the body. GLP-1 agonists reduce inflammation by interacting with brain receptors, offering new insights into metabolic disease treatment.
A new study suggests that a rapid increase in insulin after a meal may actually be an indicator of good health to come. The research found that higher corrected insulin response levels were linked with better beta-cell function, lower glucose levels, and reduced risk of developing pre-diabetes or diabetes.
A landmark trial found that a widely used diabetes drug, metformin, is not effective against the most common forms of early-stage breast cancer. However, researchers discovered a potential benefit for individuals with HER2-positive breast cancer, which accounts for about 20% of all breast cancers.
A team of Canadian scientists developed a scalable serology assay to track COVID-19 antibodies, informing public health decisions and vaccine timing. The assay has been used in over 30 studies across Canada, capturing natural infection and vaccination responses with high accuracy.
Scientists have discovered four basic patterns of how connections are made in the brain of a tiny worm, which could provide insights into human brain development. The researchers used electron microscopes to reconstruct the full brain of eight individuals and found that new connections are added as animals grow older.
Scientists at Sinai Health discover that all cancers fall into two categories based on the presence or absence of YAP. This binary rule reveals different drug sensitivities and resistance in each classification, offering a new strategy for treating aggressive forms of cancer.
Researchers at Sinai Health have developed a new tool to better understand the organization of living human cells. By creating a detailed map of protein localization across all compartments in human cells, the team has gained valuable insights into cellular function and disease mechanisms.
Researchers at Lunenfeld-Tanenbaum Research Institute discover WAVE2's crucial role in regulating immune system balance. Disabling WAVE2 in mice leads to severe autoimmunity and inflammation, highlighting its importance in maintaining a balanced immune response.
A new COVID-19 screening platform, C19-SPAR-Seq, has been developed to rapidly analyze thousands of samples for variants. The platform boasts a sensitivity rate greater than 95%, making it a crucial tool in the fight against the pandemic.
A genetic connection to aggressive prostate cancer has been discovered, increasing the risk by threefold for men with a specific gene variant. The study's findings may lead to the development of a blood test to predict disease severity and aid in targeted treatment.
Scientists have discovered a unique biochemical connection between cell membranes and mitochondria, regulating cellular energy production. This finding has implications for understanding diseases linked to mitochondrial dysfunction, including cancer and neurodegenerative disorders.
A randomized trial found that telephone-based weight loss advice reduced breast cancer recurrence risk by lowering weight and inflammation. Postmenopausal women with breast cancer who received lifestyle coaching via phone achieved comparable sustained weight loss to in-person consultations.
Researchers discovered a novel conceptual framework that explains how neurons establish spatial polarity and direction using netrin and Wnt signaling pathways. The study found that these pathways work redundantly in guiding cell migrations along different axes.
Researchers found that low vitamin D levels combined with increased parathyroid hormone (PTH) levels are associated with pre-diabetes and diabetes. The study suggests that assessing the entire PTH/25-OH-D axis is necessary when studying the impact of vitamin D on glucose metabolism.
Researchers developed a novel compound, Sticky-trap, to treat retinopathy by selectively closing off abnormal blood vessels without affecting healthy ones. The treatment has shown promise in mice and may lead to a new class of pharmacological entities for various conditions.
Researchers discovered that Mgat5 gene deficiency leads to improved glucose control and resistance to high calorie diets. The hexosamine biosynthesis pathway (HBP) enhances glucagon receptor sensitivity to increase liver glucose production.
Researchers at the Lunenfeld-Tanenbaum Research Institute used baker's yeast to study drug interactions, finding that one-fifth of combinations suppress each other's effectiveness and increasing the risk of adverse reactions. The study's findings have implications for personalized medicine and optimization of combination therapies.
A new study published in Diabetes Care found that women who fail to lose excess weight within the first year after giving birth are at increased risk for developing diabetes and cardiovascular disease. The research followed 305 patients and discovered that those who gained weight showed a clear increase in risk factors.
Research reveals cells shut down DNA repair processes during cell division to prevent chromosome fusions, a process that could lead to cancer. Telomeres fuse together when DNA repair is re-activated, causing defective chromosomes.
Researchers have identified a novel role for the adaptor protein p66shc in regulating glucose metabolism, suggesting its potential as a therapeutic target for cancer and diabetes. Silencing p66shc enhances glucose metabolism and cell growth, indicating it may act as an energy sensor that responds to nutrient availability.
