Do GLP-1 drugs cause cancer? New review says no, may even protect

A comprehensive review in The Journal of Clinical Investigation finds no overall link between GLP-1 receptor agonists and increased cancer risk, countering early safety concerns. Instead, evidence suggests possible protective effects for certain cancers, supported by metabolic and immune-modulating mechanisms.

GLP-1 drugs calm inflammation beyond diabetes and weight loss

This Journal of Clinical Investigation review describes how glucagon-like peptide-1 (GLP-1)–based medicines reduce systemic and tissue inflammation through both weight-dependent and weight-independent mechanisms. It details preclinical and clinical evidence linking GLP-1 receptor activation to cardiovascular, renal, hepatic, neural, and joint anti-inflammatory effects while outlining uncertainties and future research needs.

Motor protein Myosin II regulates temperature sensitivity of immune cells

Temperature is a key physiological factor that determines the speed of immune reactions. While this may seem obvious, it has remained largely unexplored at the single-cell level-until now.

Over one-third of men would rather endure stressful situations than discuss prostate health

A new survey from Orlando Health reveals that over one-third of men (38%) would rather endure stressful situations, such as watching their team lose a big game or being stuck in traffic, than discuss their prostate health.

New review illuminates the intricate connections between gut microbiota and sleep regulation

A comprehensive review published today in Brain Medicine illuminates the intricate connections between gut microbiota and sleep regulation, establishing the microbiota-gut-brain axis as a critical pathway in understanding and potentially treating sleep disorders.

Stress hormones may silence crucial neuronal genes through specific RNA molecules

What if the brain's response to stress could be read not in fleeting neurotransmitter bursts, but in the quieting of genes deep inside chromatin? Researchers at the University of Alabama at Birmingham have now shown that stress hormones may silence crucial neuronal genes through an unexpected class of RNA molecules that operate not by encoding proteins, but by reshaping the genome's architecture.

Study shows benefits of telemedicine for people with type 1 diabetes

People with type 1 diabetes achieved significantly better long-term blood glucose when their levels were monitored by healthcare professionals in real time, via a sensor under the skin, and they received regular advice in their daily lives.

New study finds no increased risk of heart and brain infarctions for transgender women

Contrary to previous research, transgender women who use the hormone oestradiol for their transition do not have an increased risk of heart attack and stroke compared to men in the general Dutch population.

Study reveals how "P bodies" heavily influence a cell's fate

How do stem cells know what to become? Nearly three decades after scientists isolated the first human embryonic stem cells, researchers are still working hard to understand precisely how a single, undifferentiated cell can become any one of the roughly 200 cell types that make up the human body.
