Incredible news: Polish scientists find a way to "unplug" cancer’s immortality. Wonderful news! A team of researchers from the Jagiellonian University has discovered a molecule that effectively disrupts DNA replication and repair processes by blocking the function of PCNA—a protein that plays a critical role in these mechanisms. This fundamental discovery paves the way for innovative cancer therapies. Following the necessary clinical trials, this molecule (or its derivatives) could be delivered as a drug using nanoparticle carriers directly to cancer cells, effectively halting their division. At the heart of every cancer cell lies the PCNA protein. Think of it as a "construction manager" that ensures the cancer’s DNA is copied without errors and repairs any damage. This protein is what makes cancer feel nearly indestructible. The team led by Dr. hab. Wojciech Strzałka has discovered a molecule that acts as a precision brake, stripping the cancer of its ability to survive and multiply. The Team Behind the Breakthrough Pictured are the innovators from the JU Faculty of Biochemistry, Biophysics, and Biotechnology (from left): Dr. Arkadiusz Borek, Dr. Ewa Kowalska, Dr. hab. Wojciech Strzałka, and Dr. hab. Monika Bzowska. This is a massive achievement! Congratulations to the entire team!
