New lab-grown organoids accurately mimic pediatric brain tumor biology

Efforts to identify and evaluate next-generation therapeutics for pediatric brain tumors are easily stymied by the quality and availability of laboratory models for research. To address this issue, scientists at St. Jude Children's Research Hospital developed patient-derived tumor organoids and tumor organoid xenografts that accurately reflect the biologic underpinnings of embryonal brain tumors.

Researchers discover how stress signals weaken the aging immune system

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their effectiveness. Normally, HSCs can both self-renew and generate a balanced mix of blood cells, but over time they produce fewer new cells, favor certain cells such as myeloid cells over lymphoid cells, and struggle to support a robust immune response.

New RNA sequencing method improves rare disease diagnosis

Researchers from Children's Hospital of Philadelphia (CHOP) developed a new RNA sequencing strategy that can reveal how genetic variants disrupt gene function and improve the diagnosis of rare diseases.

New grant funds AI search for genetic targets to treat Alzheimer's

With a new $6.2 million, five-year grant from the National Institute on Aging, researchers at Case Western Reserve University will use artificial intelligence (AI) and machine learning to identify possible genetic targets to treat Alzheimer's disease.

Dutch study shows off-label targeted therapies benefit more cancer patients

The largest published prospective evaluation of off-label targeted cancer therapies has shown that more patients could benefit from existing drugs.

AP-1 proteins help cancer cells rewire genes to survive treatment

A long-standing mystery in cancer treatment is how tumor cells so often become resistant to drugs, even ones they have never encountered before.

Study identifies new genes linked to severe pregnancy sickness

The USC research team that recently identified the hormone-encoding gene GDF15 as a key driver of pregnancy sickness has identified 9 additional genes linked to its most severe form, hyperemesis gravidarum (HG).

How next-generation proteomics is decoding the language of life

This review examines how next-generation protein sequencing and analysis technologies are expanding proteomics beyond the limits of mass spectrometry, especially for detecting proteoforms and analyzing proteins at single-molecule resolution. It highlights maturing fluorescence-based and nanopore-based platforms that could complement existing methods and deepen insight into protein sequence, structure, function, and modification states.

Scientists use whole exome sequencing to discover a new rare genetic disease

Scientists at Sanford Burnham Prebys Medical Discovery Institute and an international team of collaborators used a genetic sequencing technique called whole exome sequencing to discover a new rare genetic disease.

Study finds higher anxiety and depression in children with brain injuries

A new study, published today in JAMA Network Open, reveals that schoolage children and adolescents with medically diagnosed traumatic brain injury (TBI) have significantly higher rates of anxiety/depression, and strong family support and resilience helps alleviate some of it.

Protein complex cohesin found essential for guiding cell identity decisions

Temporarily disabling a protein complex that organizes DNA into loops inside the cell's nucleus drastically disrupted the three-dimensional structure of the genome, but surprisingly most genes continued to function as usual, Weill Cornell Medicine researchers found.

Rat hepatitis E virus may be a hidden cause of hepatitis in humans

This Nature Communications review argues that rat hepatitis E virus is an emerging zoonotic cause of hepatitis that is likely underdiagnosed because current tests are limited and awareness remains low. It shows that ratHEV is widespread in urban rodent populations, can infect humans and some other animals, and may spread mainly through indirect environmental exposure rather than direct rodent contact.

Genetic variants may reduce effectiveness of popular diabetes drugs

More than a quarter of people with Type 2 diabetes take GLP-1 receptor agonists, but the popular diabetes drugs might not work as well for people who have certain genetic variants, according to a new study by Stanford Medicine scientists and their collaborators.
