First ALS patient shows sustained improvement after custom RNA therapy

A man with rare amyotrophic lateral sclerosis (ALS) experienced improved symptoms and maintained his career as a physician one year after receiving the first antisense oligonucleotide therapy targeting his specific genetic mutation. The treatment, delivered via spinal injection, reduced biomarkers of neuron damage to normal levels without serious side effects. Researchers describe this as a foundational step for treating neurodegenerative diseases caused by rare mutations, noting that the drug was developed in just three years compared to the decade-long timelines for common mutations.

"World's First Gene-Edited Pig Liver Transplant Offers Hope for Organ Donor Shortages"

Chinese scientists have successfully performed the world's first gene-edited pig liver transplant on a brain-dead patient, marking a breakthrough in addressing organ shortages. The edited pig liver, designed to reduce organ rejection, showed good blood and liver bile flow with no signs of rejection 96 hours after the surgery. This xenotransplantation method could potentially benefit more patients with end-stage liver disease, offering a new option for clinical application, although it poses ethical challenges and is currently seen as a temporary alternative to human liver transplants.
