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).

Newly discovered molecular pathway may explain how AML develops

Researchers at UC Santa Barbara have discovered a molecular pathway that may explain how a particularly deadly form of cancer develops. The discovery may lead to new cancer therapies that reprogram cells instead of killing them. The findings are published in a recent paper in the Journal of Biological Chemistry.

Study investigates how bacteria change their disguise to evade vaccines

Genetics has provided surprising insights into why vaccines used in both the UK and US to combat serious childhood infections can eventually fail. The study, published today in Nature Genetics, which investigates how bacteria change their disguise to evade the vaccines, has implications for how future vaccines can be made more effective.

Study finds protein's entwined arm movements may control fate of potentially toxic payload

Like a magician employing sleight of hand, the protein mitoNEET -- a mysterious but important player in diabetes, cancer and aging -- draws the eye with a flurry of movement in one location while the subtle, more crucial action takes place somewhere else.

Study finds link between body clock hormone melatonin, type 2 diabetes

A study published in Nature Genetics today has found new evidence for a link between the body clock hormone melatonin and type 2 diabetes. The study found that people who carry rare genetic mutations in the receptor for melatonin have a much higher risk of type 2 diabetes.

DNA sequencing for difficult diagnoses of mitochondrial diseases may hit clinics soon

Identifying complete DNA sequences could identify difficult-to-diagnose diseases in humans. This concept is being used for the first time in a clinic. MitoExome sequencing uses new technologies known as next-generation sequencing (NGS) to decode all of the genes associated with mitochondria. Mitochondria are a capsule shaped organelle present within the cell. It is the powerhouse of the cell and its genes are inherited completely from the mother.

Researchers identify possible cause for loss of tumor suppressor genes

Researchers at Queen's University in Kingston, Canada have identified a possible cause for the loss of a tumour suppressor gene (known as PTEN) that can lead to the development of more aggressive forms of prostate cancer.

New technique to overcome genetic oddity of P. falciparum

The parasite that causes malaria is a genetic outlier, which has prevented scientists from discovering the functions of most of its genes. Researchers at National Jewish Health and Yale University School of Medicine have devised a technique to overcome the genetic oddity of Plasmodium falciparum, the major cause of human malaria.

Ovarian cancer patients with BRCA1 or BRCA2 mutations more likely to survive

Ovarian cancer patients who carry BRCA1 or BRCA2 mutations are significantly more likely to survive the disease than women without these faulty genes, according to research published in the Journal of the American Medical Association.

Genetic variation predisposes children to complications linked with second-generation anti-psychotics

Researchers have found a genetic variation predisposing children to six-times greater risk of developing metabolic syndrome when taking second-generation anti-psychotic medications. Metabolic syndrome is a cluster of conditions that are risk factors for cardiovascular disease.

Novel detection of ovarian cancer in early stages

Ovarian cancer is often detected at a late stage and it is the leading cause of death due to gynecological cancers, and the sixth leading cause of cancer death in women. According to latest discovery by researchers at Sydney’s Garvan Institute there may be a way this killer cancer is detected earlier.
