Study creates new human organoid models of fatty liver disease

The researchers created new human organoid models of fatty liver disease. They used these models to shed light on drug responses and built a CRISPR-screening platform to find new disease mediators and potential therapeutic targets. These models will aid in the testing and development of novel treatments for fatty liver disease, as well as in gaining a better understanding of the disease's biology.

Study finds how surgery can prevent abdominal aneurysms

When the artery that supplies the stomach and liver bulges and ruptures, 50 percent of patients die before they reach the hospital. This "silent killer," known as abdominal aortic aneurysm, killed Albert Einstein and is responsible for nearly 5,000 deaths in the United States each year. Researchers have discovered new clues that could eventually lead to earlier detection methods that could save lives in the future.

Researchers find how to compensate for loss of gene function

Living organisms have a knack for persisting in the face of challenges. For instance, when genes malfunction, organisms may be able to compensate by activating redundant genes with similar functions, called paralogs.

Researchers reveal role of polyphenols in regulating inflammatory immune responses

PCB2DG, an anti-inflammatory polyphenol, inhibits glutamine absorption by targeting and directly interacting with the main glutamine transporter protein, alanine serine cysteine transporter 2 (ASCT2). This reduction in intracellular glutamine accumulation in CD4+ T cells also inhibits the production of interferon-gamma, or IFN-, indicating that dietary polyphenol therapy for autoimmune illnesses may be beneficial in the future. Furthermore, one of the study's major accomplishments was the discovery of ASCT2 as the target protein of PCB2DG, which opens up new avenues for research into the effects of dietary polyphenols on immunological responses.
