4 Mwezi wa kumi, 2025 Picha iliyoundwa na AI
Researchers have identified a novel protein biomarker that detects lung cancer at an early stage with high accuracy. The discovery, detailed in a recent study, could enhance screening methods and improve patient outcomes. Clinical trials showed promising results in identifying the disease before symptoms appear.
Researchers develop new method for early cancer detection
Scientists at the University of Cambridge have unveiled a groundbreaking blood test that detects cancer earlier than existing methods. The technique analyzes circulating tumor DNA with high accuracy. This innovation could revolutionize screening and treatment worldwide.
Scientists uncover cancer cells' mitochondrial energy surge under pressure
5 Mwezi wa kumi, 2025 Imeripotiwa na AI
Researchers have discovered that cancer cells respond to physical squeezing by rapidly deploying mitochondria to the nucleus, delivering a burst of ATP to repair DNA damage and ensure survival. This mechanism, observed in lab experiments and patient biopsies, could inspire new strategies to halt cancer spread. The finding redefines mitochondria's role as dynamic responders rather than static energy sources.
Bacteria in tumors produce molecule to boost cancer chemotherapy
Scientists have identified a molecule produced by bacteria inside tumors that enhances the effectiveness of chemotherapy against colorectal cancer. The compound, 2-methylisocitrate, damages cancer cell DNA and disrupts their metabolism. This discovery could lead to new treatments that make existing drugs more potent.
