Gene therapy shows promise in tackling common cause of childhood blindness

The results of a first-in-human clinical trial of gene therapy to treat a common cause of genetic blindness have shown partial reversal of sight loss in some patients. X-linked retinitis pigmentosa, caused by mutations in RPGR gene, is the most common cause of blindness in young people. The inherited mutations […]

Chemotherapy rewires a novel resistance-promoting signaling pathway in ovarian cancer

Researchers from Karolinska Institutet along with clinicians from the Karolinska University Hospital have discovered a new molecular mechanism of cell oncogenic signaling switch, which is induced by platinum chemotherapy and contributes to treatment resistance in ovarian cancer. Even with the continuous development of new anti-cancer treatments, chemotherapy is used as […]

Scientists explore how the brain trains muscles to move

But research into the neurological process of learning how to move suggests that it might be more accurate to say “mindful practice makes perfect.” This may not sound revolutionary to anyone who’s ever shot a free throw like LeBron or knocked a golf ball like Nicklaus. Star athletes understand that […]
