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).

Scene-of-the-crime DNA analysis is moving a step closer

Currently DNA analysis is both time-consuming and expensive, but researchers at the Polymer Electronics Research Centre (PERC), within the Faculty of Science and the Faculty of Medical and Health Sciences, hope to change that by inventing a system that provides direct, real-time detection of DNA.

Human endogenous retroviruses (HERVs)

Human endogenous retroviruses (HERVs) have been the subject of a great deal of investigation in recent years. It has been established that HERVs cause some genetic diseases and there is strong circumstantial evidence for a link to some types of cancer and autoimmune diseases, but what else do we need to know about these unique organisms?

Fossil record of the human immune system reveals antibodies that block cancer metastasis

A team of researchers at The Scripps Research Institute has reconstructed the "fossil record" of the immune systems of a group of human cancer patients to investigate if they had ever produced antibodies against their disease.

Evidence of exposure to a monkey virus possibly related to cancer has been found in the blood of North American zoo workers

The virus, a polyomavirus known as simian virus 40 (SV40), has long been a subject of public health concern, in part because it has been shown to cause cancer in laboratory animals, and some investigators have reported SV40 DNA in human tumors.

Five advanced tests provide answers to couples with unexplained infertility

For couples struggling with infertility, "all routine tests came back negative" are not the words they want to hear. With up to 15% of couples with "unexplained infertility" and another 3% struggling with recurrent pregnancy loss, advanced tests help doctors find answers for their most challenging cases.
