474-p53 Inactivation in Breast Cancer Metastasis
This research explores how the inactivation of the p53 tumor-suppressor gene significantly increases the likelihood of breast cancer spreading to the brain. While mutations and chromosomal losses in p53 are common in many cancers, this study identifies a specific link to brain metastasis through the reprogramming of fatty acid metabolism. Scientists discovered that p53-deficient cells thrive in the brain by upregulating the SCD1 enzyme via the DEPDC1/SREBP1 pathway, allowing them to exploit lipids provided by astrocytes. Because these cancer cells become highly dependent on this metabolic…
