Researchers discover dozens of genetic defects important for immune defence - relevant for patients with rare diseases

Two studies identify 22 previously unreported NFKB1 variants linked to immune system dysfunction, including reduced expression of the protein and altered gene expression. The findings suggest targeted inhibition of NFkB signaling pathway components as an attractive therapeutic approach for treating these diseases.

Molecular switch controls life expectancy

A new study reveals that the protein CHIP can regulate insulin receptor signals more efficiently alone than in a paired state. This finding suggests that maintaining a balance between monomeric and dimeric states of CHIP is crucial for proper cellular function.

Physical activity may have a stronger role than genes in longevity

A recent study published in the Journal of Aging and Physical Activity found that higher levels of light physical activity and moderate-to-vigorous physical activity were associated with lower risk of death. In contrast, higher sedentary time was linked to increased mortality risk, regardless of genetic predisposition for longevity.

Scientists create a DNA test that identifies Lyme disease in horses

A Rutgers scientist has developed a highly sensitive DNA test that can detect Lyme disease in horses, a condition that can cause long-term complications. The test, called genomic hybrid capture assay, was tested on a sick horse and successfully identified the pathogen, allowing for early diagnosis and treatment.

How the genome is packed into chromosomes that can be faithfully moved during cell division

The Gerlich Group at IMBA found that histone acetylation establishes a sharp surface boundary on chromosomes, resisting microtubule perforation. Chromatin phase separation and DNA looping by condensin cooperates to build mitotic chromosomes with unique physical properties.

Gut microbe peptide implicated in triggering type 1 diabetes

Researchers at Joslin Diabetes Center identified a human gut bacterium that makes a protein mimicking the insulin peptide targeted by the immune system in type 1 diabetes. The presence of this bacterium accelerates the onset of diabetes in a mouse model and is linked to its development in children at genetic risk.

When did the genetic variations that make us human emerge?

Researchers have dated the emergence of genetic variants characteristic of modern humans to two distinct periods: one around 40,000 years ago, linked to population growth and divergence from Africa, and an older one over 100,000 years ago, reflecting the species' greatest diversity in Africa. These findings complement the mosaic nature...

Synthetic tools conduct messages from station to station in DNA

Researchers used deactivated Cas9 proteins to target key segments of the human genome and synthetically trigger gene transcription. The study revealed that enhancers can send messages in both directions, but with a predominant regulatory mode where an enhancer tracks toward corresponding promoters.
