Semaglutide, liraglutide, and their effects beyond diabetes/obesity
Drugs like semaglutide (a.k.a. Ozempic/Wegovy) that activate the glucagon-like peptide-1 receptor (GLP-1R) are a promising therapy for obesity and type 2 diabetes (T2D). Animal studies suggest that these drugs likely function by stimulating GLP-1R on …
INTRODUCTION: GLP-1 receptor agonists (GLP-1RA) are glucose- and body weight-lowering therapies provided with cardio-renal benefits. Use of GLP-1RA in older adults with type 2 diabetes mellitus (T2DM) is increasing but concerns remain about their safety …
INTRODUCTION: Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are widely used for weight management and type 2 diabetes, but reports of reduced skin laxity and volume have raised aesthetic concerns. This study evaluates the first …
Different types of dietary restriction (DR) have been practiced by humans for religious and medical purposes for millennia, but only during the past three decades has the scientific study of DR at cellular and molecular …
Background: GLP1 receptor agonists (GLP1RAs) and SGLT2 inhibitors (SGLT2Is) have established cardiovascular benefits for patients with type 2 diabetes mellitus (T2DM), with similar class-level effectiveness found in previous studies. However, real-world comparative effectiveness assessments of …
Lisa Mosconi discusses sex-specific Alzheimer's prevention strategies for midlife women, emphasizing behavioral interventions (exercise, sleep, nutrition, stress management) as the primary prevention tools while highlighting emerging pharmaceutical options like GLP-1 agonists and klotho. The conversation …
A new Nature study finds castration extends lifespan ~10% across animal species and historical Korean eunuchs lived 14-19 years longer, but the mechanism likely involves reduced risky behavior and altered growth hormone pathways—not simply low …
Researchers found that liraglutide, a GLP-1 drug used for diabetes, improved mitochondrial function and reduced oxidative stress in aging heart cells made insulin-resistant in the lab. The effect required a protein called casein kinase 2 …
