Cancer suppressor gene links metabolism with cellular aging
The tumor suppressor protein p53 is an attractive target for drug developers. But this path has so far proven difficult, as most p53 regulatory proteins operate via protein-protein interactions, which make for poor drug targets, ...

Breast cancer risk linked to early-life diet and metabolic syndrome
Striking new evidence suggesting that diet and related factors early in life can boost the risk for breast cancer—totally independent of the body's production of the hormone estrogen—has been uncovered by a team of researchers ...

Blocking telomerase kills cancer cells but provokes resistance, progression
Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive ...

BRAF inhibitor treatment causes melanoma cells to shift how they produce energy
A multi-institutional study has revealed that BRAF-positive metastatic malignant melanomas develop resistance to treatment with drugs targeting the BRAF/MEK growth pathway through a major change in metabolism. The findings, ...
