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).

Study unravels how mitochondria call for help when under stress

Originally, the powerhouses of higher cells, the mitochondria, were independent organisms. Researchers at Goethe University Frankfurt have investigated to what extent their metabolism has blended with that of their host cells in the course of evolution, using the example of a mitochondrial stress response.

Transcription factors may drive development of different colorectal cancer subtypes

New research in colorectal cancers directed by investigators at the Johns Hopkins Kimmel Cancer Center suggests that expression of transcription factors — proteins that help turn specific genes on or off by binding to nearby DNA — may play a central role in the degree of DNA methylation across the genome, contributing to the development of different subtypes of these cancers.
