Loss of Gα13 in B-cells linked to increased lymphoma risk due to dietary glutamine

Researchers find that the deletion of Gα13 in B-cells increases lymphoma risk by enhancing proliferation in gut-associated lymph nodes. Dietary glutamine significantly promotes these effects, highlighting a crucial link between diet and cancer.

Study unveils dual roles of TNF-α receptors in tissue regeneration and cell death

A study published in The EMBO Journal opens new perspectives to better understand how the molecular mechanisms involved in regenerative medicine work.

Canadian experts urge caution on free genetic testing and data sharing

Free genetic testing, offered partially or fully subsidized by industry, may have trade-offs, and health systems in Canada must carefully weigh potential clinical, ethical, and legal considerations to protect patient data, authors argue in a CMAJ (Canadian Medical Association Journal) commentary https://www.cmaj.ca/lookup/doi/10.1503/cmaj.231588.

Eight-week vegan diet linked to epigenetic age reduction in identical twins

Eating a vegan diet for eight weeks is associated with reductions in biological age estimations based on levels of DNA methylation -; a type of chemical modification of DNA (known as an epigenetic modification) that alters gene expression but not DNA itself.

New zwitterionic polyion developed for effective plasmid DNA delivery in muscle cells

Researchers from Tokyo Metropolitan University have created a new drug delivering molecule, a zwitterionic polymer complex that can help get plasmid DNA inside cells when injected into skeletal muscle, a crucial step in the expression of therapeutic RNA and proteins.

Study finds genetic factors key to post-stroke cardiovascular risks

Research identifies genetic and molecular risk factors for cardiovascular outcomes after an initial stroke, uncovering potential therapeutic targets to improve patient prognoses.

Scientists explore early life factors contributing to SMA

Spinal muscular atrophy (SMA) is a severe neurological disease for which there is presently no cure, although current therapies can alleviate symptoms. In the search for better treatment options, scientists at DZNE and the Dresden University of Technology are now drawing attention to previously unnoticed abnormalities in embryonic development. They base their argument on studies of so-called organoids: Laboratory-grown tissue cultures that can reconstruct disease processes. Their findings are published in the journal Cell Reports Medicine.

Breakthrough therapy heals spinal cord injuries

In November 2021, Northwestern University researchers introduced an injectable new therapy, which harnessed fast-moving "dancing molecules," to repair tissues and reverse paralysis after severe spinal cord injuries.

New biomarker helps determine the optimal treatment for colon cancer

Many people with stage II or III colon cancer receive additional, or adjuvant, chemotherapy following surgery. However, clinical trials have shown that this treatment doesn't improve the chances of survival for every patient. A study published July 25th, 2024 in Cell Reports Medicine identifies and validates a 10-gene biomarker that potentially predicts whether a stage II or III colon cancer patient will benefit from adjuvant chemotherapy.

Unraveling the microbial dynamics of spontaneous fermentation

Shibazuke is a traditional Japanese eggplant pickle produced by the process of fermentation using lactic acid bacteria (LAB). LAB which is commonly present in vegetables causes the spontaneous fermentation of vegetables, resulting in the distinctive acidic flavor of pickles. While LAB is beneficial, other species of bacteria and microbes that may be present in the food source can affect the food quality and safety. Advancements in the areas of food technology and nutrition have allowed the large-scale fermentation of pickles via industrial fermenters, where conditions that affect fermentation like temperature, pH-acid levels, and salt content are closely monitored.

New guidelines expand BRCA testing and screening for men

More and more studies show that men face risks of cancer from BRCA1 and BRCA2 genetic mutations that are most often associated with breast and ovarian cancers in women.

Cellular competition determines X chromosome usage in female bodies

A new study published in Nature Genetics by the Lymphoid Development Group at the MRC Laboratory of Medical Sciences has reveals that the contribution of cells expressing maternal or paternal X chromosomes can be selectively skewed in different parts of the body. The study leverages human data from the 1000 Genomes Project combined with mouse models of human X chromosome-linked DNA sequence variation to advance our fundamental understanding of development in biologically female individuals who have two X chromosomes.
