Medical Xpress / Cancer cell study sheds light on cachexia's origins
New research from the University of Oklahoma, published today in Cancer Cell, describes for the first time a "triangle regulation theory" of cancer-induced cachexia and anorexia. Cachexia is a muscle-wasting and fat-loss ...
Medical Xpress / Why visceral fat triggers diabetes: Study points to loss of protective macrophages
Scientists at the University of Pittsburgh School of Medicine discovered a surprising new way the body can fight insulin resistance and diabetes—by boosting a special type of "good" immune cell in fat tissue.
Medical Xpress / Unraveling the mystery of why some cancer treatments stop working
Cancer researchers working on immunotherapies have made a big discovery: SLAMF6, a molecule on the surface of immune cells that prevents T cells from effectively attacking tumors—and, in mice, they've found a way to neutralize ...
Medical Xpress / Light-based sensor detects early molecular signs of cancer in the blood
Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to spot early signs of cancer ...
Medical Xpress / AI-built maps reveal causal gene regulation across Alzheimer's brain cell types
Researchers led by Min Zhang and Dabao Zhang of the University of California, Irvine's Joe C. Wen School of Population & Public Health have created the most detailed maps to date showing how genes causally regulate one another ...
Medical Xpress / Newly identified brain circuit and cells link prior experiences to appetite
Our past experiences shape how much we eat and where and what we choose to eat. Using preclinical models, researchers from Mass General Brigham and the Broad Institute of MIT and Harvard have identified brain cells that translate ...
Medical Xpress / Cholesterol crystals may trigger some liver disease
Cholesterol crystals in the liver may stiffen the organ early in those with metabolic dysfunction-associated steatotic liver disease (MASLD)—well before scarring develops—according to new research from a team in the Perelman ...
Medical Xpress / Cumulative lead exposure linked to increased Alzheimer's and dementia risk, study finds
As dementia cases continue to rise in the United States, new research from the University of Michigan School of Public Health reveals that older Americans with cumulative lead exposure face a substantially higher risk of ...
Medical Xpress / Nearly half of people facing cataract-related blindness still need surgery
The World Health Organization (WHO) has called on countries to improve their global cataract care, after new findings suggest that millions of people living with cataract still do not have access to simple, sight-restoring ...
Medical Xpress / Academic pressure at 15 tied to higher depression symptoms through age 22
Pressure to achieve at school at age 15 is linked to depressive symptoms and risk of self-harm, and the association appears to persist into adulthood, finds a study led by University College London (UCL) researchers.
Medical Xpress / New characteristics of aggressive prostate cancer identified
For the first time ever, NTNU researchers have identified new characteristics of aggressive prostate cancer. The research lays a foundation for the possibility that aggressive prostate cancer can probably be detected through ...
Medical Xpress / Which childhood abuse survivors are at elevated risk of depression? New study provides important clues
Scientists have identified a pattern of gene activity present in some female survivors of childhood abuse that is associated with an elevated risk of depression.
