CRISPR Tool Targets Neuron Gene Repair

September 15, 2025 由 AI 报道

Stanford researchers have created a CRISPR-based technology to target RNA in neurons, enabling repair processes for genetic diseases. The method addresses key challenges in Cas9 delivery and DNA repair. It reveals unique genome editing rules in neurons, paving the way for targeted therapies.

DNA scar catalog opens paths to overcome cancer drug resistances

October 03, 2025 由 AI 报道

Researchers at Spain's National Cancer Research Centre (CNIO) have developed a comprehensive catalog of mutational 'scars' in DNA caused by cancer. This breakthrough, published in Nature, could help bypass resistances to treatments like PARP inhibitors. The study analyzes thousands of tumor samples to identify key genetic patterns.

Gene mutation raises disease risk by 50 percent

September 30, 2025 由 AI 报道

A new study has identified a specific gene mutation that increases the risk of type 2 diabetes by 50 percent. Led by researchers at the University of California, Berkeley, the findings come from a five-year analysis of 1,000 participants. The discovery highlights potential pathways for early detection and treatment.

Study shows older fathers transmit more disease mutations through selfish sperm

A new study reveals that older men pass on significantly more disease-causing genetic mutations to their children due to the rapid proliferation of mutant sperm stem cells. Researchers found that the proportion of mutated sperm rises sharply with age, from 1 in 50 for men in their early thirties to nearly 1 in 20 by age 70. This phenomenon, driven by 'selfish' mutations, heightens risks for severe disorders in offspring.

Study identifies potential genetic subtypes of autism

Researchers have proposed that autism spectrum disorder may consist of genetically distinct subtypes, based on an analysis of large-scale genetic data. This finding could lead to more personalized approaches to diagnosis and treatment. The study highlights variations in genetic markers among individuals with autism.
