A Decade of Change: Advances in the Classification and Known Causes of Brain Tumors

For many years, the classification of gliomas relied largely on the cells’ general appearance, or histological characteristics, as seen under a microscope. Today, our understanding of glioma subtypes has expanded to include the molecular and genetic variants that can influence a tumor’s development, prognosis, and response to treatment. Until recently, […]

Cancer cell’s “self eating” tactic may be its weakness

Cancer cells use a bizarre strategy to reproduce in a tumor’s low-energy environment; they mutilate their own mitochondria! Researchers at Cold Spring Harbor Laboratory (CSHL) also know how this occurs, offering a promising new target for pancreatic cancer therapies. Why would a cancer cell want to destroy its own functioning […]
