Does a psychedelic need an awake brain to have lasting effects? This mouse study offers a clue

A single dose of psilocybin produced a lasting increase in sociability for at least two weeks in Cntnap2-knockout mice with social deficits, while it did not enhance sociability overall in mice with normal social behavior. The effect required 5-HT2A receptor activation and persisted when psilocybin was administered under light anesthesia, suggesting that wakefulness during the drug’s acute effects was not necessary for this behavioral response.

Scientists uncover shared gene signatures that reveal how mammals age

Researchers mapped more than 11,000 transcriptomes across mice, rats, macaques, and humans, revealing conserved molecular signatures of aging and mortality across tissues, species, and cell types. The study developed interpretable transcriptomic clocks that track age, mortality-related molecular change, chronic disease signals and responses to lifespan-altering interventions.

Novel RNA target offers hope for improving outcomes in patients with chronic limb ischemia

Mark W. Feinberg, MD, cardiologist with the Mass General Brigham Heart and Vascular Institute and professor of medicine at Harvard Medical School, is the senior author of a paper published in the Journal of Clinical Investigation, "A smooth muscle cell lncRNA controls angiogenesis in chronic limb-threatening ischemia through miR-143-3p/HHIP signaling."

Targeting ADAM10 may offer hope for retinal disease treatment

New research has found that the endothelial cell-specific A disintegrin and metalloproteinase domain-containing protein 10 (ADAM10) regulates abnormal blood vessel growth in the damaged retina, which can cause vision loss or impairment.

Targeting PME-1 may offer new strategies for treating neurological disorders and cancer

PME-1 is a protein that modifies other proteins by removing methyl groups, but high levels of PME-1 are observed in some diseases, including Alzheimer's disease (AD) and cancer.

New study reveals LRP1's crucial role in bone formation and joint development

Skeletal conditions such as developmental dysplasia of the hip (DDH), osteoporosis, and osteoarthritis affect millions worldwide, often causing chronic pain and disability. These disorders stem from complex genetic and environmental interactions that disrupt bone formation and joint development.

ASTN2 gene knockout in mice reveals key autism-related behaviors

More than 70 genes have been linked to autism spectrum disorder (ASD), a developmental condition in which differences in the brain lead to a host of altered behaviors, including issues with language, social communication, hyperactivity, and repetitive movements.

Study explores interplay between bone, adrenal glands, and aging

Figuring out how the tissues in our bones, adrenal glands, muscle and fat "talk" to each other could help scientists better understand what happens to our skeletons with age, when our bones tend to lose mass and become weaker, leaving us at risk for falls and fractures.
