Key Highlights
•
Scientists have discovered that a new type of drug can block the growth and blood vessel formation of several cancers by targeting two key proteins, HIF-1 and HIF-2, which tumors use to survive and spread. This dual-action drug was more effective than existing treatments and even helped overcome resistance to common immunotherapies in over half of the cases studied.

A new study reveals that the transition from a benign growth to aggressive pancreatic cancer is driven by a self-reinforcing “niche” created by opposing forces within the tumor. Disrupting the activity of key cancer genes like p53 or KRAS can collapse this niche and stop the cancer from becoming malignant.

Researchers found that the movement of molecules inside a cell is best described by a “porous media” framework, a model that applies not just to simple molecules but also to more complex biological ones. This challenges previous assumptions and provides a more accurate way to understand how substances travel and function within our cells.
