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).

CPRIT awards $36.7 million grant to UT Southwestern for cancer research

The Cancer Prevention and Research Institute of Texas has awarded more than $36.7 million in new grants to investigators at UT Southwestern Medical Center to support cancer-related projects and to recruit pre-eminent cancer investigators.

State laws regarding baby blood samples analyzed

State laws and policies governing the storage and use of surplus blood samples taken from newborns as part of the routine health screening process range from explicit to non-existent, leaving many parents ill-informed about how their babies' left over blood might be used, according to a team led by a member of the Johns Hopkins Berman Institute of Bioethics, in collaboration with researchers from the University of Utah. A report on their analysis of the subject is published March 28 in the journal Pediatrics.

Genetic link to attempted suicide discovered - Findings could lead to new avenues of treatment

Johns Hopkins scientists, reporting in the journal Molecular Psychiatry, have identified a small region on chromosome 2 that is associated with increased risk for attempted suicide. This small region contains four genes, including the ACP1 gene, and the researchers found more than normal levels of the ACP1 protein in the brains of people who had committed suicide. This protein is thought to influence the same biological pathway as lithium, a medication known to reduce the rate of suicidal behavior.

New pill may protect DNA from radiation damage

The Japanese nuclear crisis has caused a surge in the demand of potassium iodide, causing shortages not only in Japan, but as far away as California, western Canada, and even southeastern Russia. Although potassium iodide does not provide generalized radiation protection because it only shields the thyroid, manufacturers and pharmacies are being bombarded with orders as the radiation hysteria mounts.

Essex scientists receive £205,000 grant for breast cancer research

Scientists from the University of Essex have received a £205,000 grant from Cancer Research UK to investigate the early reversible changes in the genes associated with breast cancer development.

New discovery provides insight into complex Rad50 molecular motor function

Over the last years, two teams of researchers at The Scripps Research Institute have steadily built a model of how a powerful DNA repair complex works. Now, their latest discovery provides revolutionary insights into the way the molecular motor inside the complex functions - findings they say may have implications for treatment of disorders ranging from cancer to cystic fibrosis.

Researchers identify genetic conspirators underlying acute myeloid leukaemia

Researchers have described how the most common gene mutation found in acute myeloid leukaemia starts the process of cancer development and how it can cooperate with a well-defined group of other mutations to cause full-blown leukaemia.

Plasmid containing Sindbis replicase genes can destruct lung cancer

Alpha viruses, such as Sindbis virus, carry their genetic information on a single strand of RNA. On infection they use a protein, replicase, to produce double stranded RNA which is used as genetic material to make more viruses. However the body recognizes dsRNA as foreign, and infected cells initiate an immune response.

HIV uses base excision repair pathway to insert DNA into host-cell genome

The human immunodeficiency virus (HIV), the cause of AIDS, makes use of the base excision repair pathway when inserting its DNA into the host-cell genome, according to a new study led by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute. Crippling the repair pathway prevents the virus from completing this critical step in the retrovirus's life cycle.

Mersana commences XMT-1001 Phase 1b extension study in gastric cancer and non-small cell lung cancer

Mersana Therapeutics today announced the initiation of a Phase 1b extension study with its lead cancer product, XMT-1001, a novel DNA topoisomerase I inhibitor based on the company's Fleximer® polymer conjugate platform, in second-line gastric cancer and second-/third-line non-small cell lung cancer. The study will be carried out in 10 clinical centers in the US.

Scientists identify protein that plays a key role in cancer treatment resistance

Research led by Daitoku Sakamuro, PhD, Assistant Professor of Pathology at LSU Health Sciences Center New Orleans and the LSUHSC Stanley S. Scott Cancer Center, has identified a protein that enables the activation of a DNA-repair enzyme that protects cancer cells from catastrophic damage caused by chemo and radiation therapy.

Researchers identify gene that can predict hypersensitivity to epilepsy drug

Research published this week in the New England Journal of Medicine. A multinational team of scientists led by the Royal College of Surgeons in Ireland and the University of Liverpool has identified a gene that could indicate if epilepsy patients starting a common drug treatment are likely to experience side-effects ranging from a mild skin irritation to the potentially fatal Steven-Johnson Syndrome.
