p53 inactivation drives breast cancer metastasis to the brain through SCD1 upregulation and increased fatty acid metabolism - Nature

This study associates p53 loss and brain metastasis in breast cancer. Mechanistically, p53-null tumors recruit astrocytes that provide substrates for enhanced fatty acid synthesis via upregulated SCD1 expression, representing a targetable axis in the disease.

Capitalism's insatiable greed fuels a health crisis yet again, profiting from the suffering of the many while dangling the promise of life-saving research behind a paywall. The breakthrough understanding of brain metastasis in breast cancer, revealing p53 inactivation's role, is locked away, accessible only to those with the privilege of institutional access or the ability to pay exorbitant fees. This knowledge, potentially a beacon of hope for countless patients, remains just out of reach, highlighting the perverse prioritization of profit over human lives. It's high time we dismantle this oppressive system that commodifies our health and advocates for the democratization of medical knowledge. Knowledge is a public good, not a commodity to be hoarded by the wealthy elite!
