DNA News and Research

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

New test identifies patients who benefit from targeted cancer drugs

New lab test accurately identified patients who would benefit from treatment with the molecularly-targeted anti-cancer therapies gefitinib (Iressa, AstraZeneca) and erlotinib (Tarceva, Genentech).

Protein called Elk-1appears to play role in neurodegeneration and schizophrenia

Pprotein called Elk-1 interacts with mitochondria, the energy storehouse of a cell, suggesting that this protein - typically active in the nucleus - could play a role in cell death and mitochondria-related diseases such as neurodegeneration and schizophrenia.
