The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and partially break apart to bind key DNA sequences that activate division genes. Using cryo-electron microscopy, scientists captured this interaction in remarkable detail. The mechanism appears to be widespread across bacteria, offering a new window into how microbes regulate growth.

By engineering yeast cells so their survival depended on proteins switching states at the right time, scientists could rapidly select the best-performing variants. The technique produced new light-sensitive proteins that respond to different colors and improved optogenetic systems. It even evolved a protein that behaves like a tiny logic gate, activating genes only when two signals are present.

As a proof-of-concept, the authors of the study asked the AI to design synthetic fragments which activate a gene coding for a fluorescent protein in some cells while leaving gene expression patterns unaltered. They created the fragments from scratch and dropped them into mouse blood cells, where the sequence fused with the genome at random locations.

The engineered bacterium detoxified methylmercury in the gut of mice and dramatically reduced the amount that reached other tissues, such as the brain and liver. Mice given an oral probiotic containing the engineered microbe and fed a diet high in bluefin tuna had much lower methylmercury levels than expected, suggesting that a probiotic might eventually make it safer for people to consume fish. Researchers performed the tests using pregnant mice and found lower levels of methylmercury in both maternal and fetal tissues, and lower signs of mercury toxicity in the fetal brain.

The particles are created by chemically bonding iron oxide nanoparticles to regenerated silk fibroin using glutathione, enhancing their magnetic responsiveness while maintaining biocompatibility. These nanoscale carriers, roughly one-hundred-thousandth the width of a human hair, can potentially be guided externally to precise locations in the body. The platform enables localized delivery of therapeutic agents such as extracellular vesicles, regenerative factors, or drugs, offering a minimally invasive approach to treating conditions like abdominal aortic aneurysms and expanding the potential for targeted therapies in regenerative medicine.

But to date this technology -- which allows scientists to use a 'guide' RNA to modify DNA sequences and evaluate the effects -- is able to target, delete, replace, or modify only single gene sequences with a single guide RNA and has limited ability to assess multiple genetic changes simultaneously. Now, however, scientists have developed a series of sophisticated mouse models using CRISPR ('clustered regularly interspaced short palindromic repeats') technology that allows them to simultaneously assess genetic interactions on a host of immunological responses to multiple diseases, including cancer.

Researchers report that mice subjected to intermittent fasting regimes showed improved metabolic health but slower hair regeneration compared to mice with 24/7 access to food. A similar process might occur in humans, based on a small clinical trial that the team also conducted, but it's likely to be less severe since humans have a much slower metabolic rate and different hair growth patterns compared to mice.

Specifically, lower activation of the epidermal growth factor receptor (EGFR) signaling pathway occurs following reduced endocytosis. Decreased EGFR pathway activity allows LECs to switch from undergoing single-cell apoptosis to more widespread cell death in clusters. This supports faster LEC elimination and allows for proper tissue remodeling. Wed, 13 Nov 2024 12:38:42 EST https://www.sciencedaily.com/releases/2024/11/241113123842.htm
