DNA News and Research

RSS

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).

Researchers identify 34 genes associated with increased risk of ovarian cancer

A team of researchers at UCLA's Jonsson Comprehensive Cancer, Cedars-Sinai Cancer and Dana-Farber Cancer Institute have newly identified 34 genes that are associated with an increased risk for developing the earliest stages of ovarian cancer.

TET proteins help regulate gene activity vital for normal antibody production

A family of cancer suppressive proteins, known as TET proteins, help regulate gene activity via their influence on chromosomal architecture. However, until now it wasn't entirely clear how genes were activated by TET proteins to make sure that cells perform their normal functions efficiently.

First extensive analysis of proteins in patients with acute lymphoblastic leukemia

The most common form of childhood cancer is acute lymphoblastic leukemia. Researchers at Lund University in Sweden, in cooperation with Karolinska Institutet, SciLifeLab and the University of Cambridge, have now carried out the most extensive analysis to date of ALL at the protein level, by studying the activity in over 8 000 genes and proteins.
