Oncogenic Ras Sensitizes Cells to Apoptosis by Par-4

Abstract excerpt

Certain mutations in the mammalian ras gene are oncogenic and are often detected in human cancers. Oncogenic Ras induces the transcription activity of NF-kappaB that confers cell survival. Oncogenic Ras also down-modulates the expression of Par-4, a transcriptional repressor protein, that is essential but not sufficient on its own to induce apoptosis. Here we show that reintroduction of Par-4 by transient...
