Semaglutide extended lifespan in older female mice, but that was not the only finding

Late-life semaglutide treatment slowed age-related physiological decline, attenuated multiple molecular hallmarks of aging, and extended median lifespan from 742 to 834 days in aged female mice. The drug reproduced many effects of calorie restriction while providing additional benefits in exploratory behavior, spatial memory, and glucose control, suggesting that some effects extend beyond reduced calorie intake alone.

Cancer-fighting T cells need small amounts of ROS to attack tumors, study finds

New research reveals a promising new target for treating cancer by harnessing a type of molecule previously thought to do more harm than good.

Microscopic peptide droplets reduce colorectal tumor growth in mice

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed microscopic peptide droplets that deliver large amounts of gene-silencing molecules into cancer and immune cells, reducing the growth of hard-to-treat colorectal tumours by about 67 per cent in mice.

Yeast study shows how membrane lipids slow protein transport

A study in budding yeast suggests that changes in membrane lipids trigger a braking system that slows internal protein transport when the endoplasmic reticulum comes under stress, comparable to modern logistics networks where shipments are slowed when distribution hubs are under stress.

Cerebral palsy may be a trait rather than a disease

Historically, cerebral palsy (CP) was linked largely to events at birth, including prematurity or temporary loss of oxygen to the brain, but research over the past decade has suggested that genetic factors contribute to CP in many children.

Cancer drug eliminates HIV-infected cells in animal model study

Emory University researchers have provided the first proof-of-concept in a nonhuman primate model for eliminating HIV-infected cells with venetoclax, a clinically approved medication for cancer.

Brain-protecting immune cells may actually drive Alzheimer's disease

Immune cells that normally protect the body from damage by attacking foreign or infected cells are found in the brains of patients with Alzheimer's disease and related disorders at much higher levels than in healthy brains.

New optical imaging reveals metabolic activity of individual immune cells

A routine blood sample contains a diverse collection of immune cells that can reveal important clues about health and disease.

High-dose folic acid appears safe from formaldehyde toxicity

Folic acid – an essential vitamin added to flour and cereals and prescribed at high doses for cancer patients and people with blood disorders – does not elevate toxic formaldehyde in the body, according to a new Cornell University study on mice and human cancer patients who consumed high doses.

Daraxonrasib shows durable responses in RAS-mutant lung cancer

Daraxonrasib, an oral RAS inhibitor therapy, achieved durable responses in pretreated patients with RAS-mutant non-small cell lung cancer (NSCLC) in a Phase 1/2 trial led by The University of Texas MD Anderson Cancer Center.

Newly diagnosed AML patients benefit from less-intensive combination treatment

Investigators from the Mass General Brigham Cancer Institute have found that adults with newly diagnosed acute myeloid leukemia (AML) receiving a less-intensive combination of azacitidine and venetoclax had more than twice as much time before treatment failed, the leukemia returned or worsened, or they died, compared with patients receiving intensive chemotherapy.

Shared biological pathways may explain chronic fatigue across diseases

A shared biological secret that helps explain chronic exhaustion in conditions including long Covid and PTSD has been discovered by researchers at the University of East Anglia and Oxford BioDynamics.

Post-surgery immunotherapy may not benefit specific lung cancer patients

A new real-world observational study has found that adding adjuvant immunotherapy after surgery does not significantly improve survival outcomes in patients with resectable non-small cell lung cancer (NSCLC) who have already achieved a pathological complete response (pCR) following neoadjuvant chemoimmunotherapy.
