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 create new ultra-sensitive tool for chemical, DNA and protein analysis

Utilizing optical characteristics first demonstrated by the ancient Romans, researchers at the University of Illinois at Urbana-Champaign have created a novel, ultra-sensitive tool for chemical, DNA, and protein analysis.

'Vaccine patch' could make immunizations cheaper, easier

"An innovative new way to deliver vaccines could drastically improve the health of the third world, and even the first world, by making vaccines cheaper and easier to distribute and use," Business Insider reports, adding, "The 'vaccine patch' would be as easy to apply as a Band-Aid, and would be stable for weeks at room temperature."

IKBKE gene plays a key role in tobacco-induced lung cancer

Researchers at Moffitt Cancer Center have found a potential targeted therapy for patients with tobacco-associated non-small cell lung cancer. It is based on the newly identified oncogene IKBKE, which helps regulate immune response.

Researchers discover SCANR that helps protect a cell's genes against DNA interlopers

Gene wars rage inside our cells, with invading DNA regularly threatening to subvert our human blueprint. Now, building on Nobel-Prize-winning findings, UC San Francisco researchers have discovered a molecular machine that helps protect a cell's genes against these DNA interlopers.

Researchers show how gene mutations shift and evolve over time in chronic lymphocytic leukemia

Tumors are not factories for the mass production of identical cancer cells, but are, in reality, patchworks of cells with different patterns of gene mutations. In a new study, researchers at Dana-Farber Cancer Institute and the Broad Institute show, more fully than ever before, how these mutations shift and evolve over time in chronic lymphocytic leukemia (CLL) - providing a strobe-like look at the genetic past, present, and future of CLL tumors.

Study shows importance of lncRNAs for regulation of adipogeneis

Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells. When this regulation is disrupted, white fat cells are unable to accumulate lipid droplets or mature from their precursors.

FOXC2 vital to epithelial-mesenchymal transition in breast cancer

Researchers have identified a pivotal protein in a cellular transformation that makes a cancer cell more resistant to treatment and more capable of growing and spreading, making it an inviting new target for drug development.

Threat vigilance can protect soldiers against PTSD

The onset of Post-Traumatic Stress Disorder (PTSD) is unpredictable. Because it depends on the unforeseeable occurrence of traumatic events, it is difficult to identify preventative or causative factors. Scientists typically turn to patients who have already developed PTSD to study the disorder, but that means they can't draw comparisons to their psychological state prior to experiencing trauma.

Blogs examine root causes, implications of myths about polio vaccination

Citing a review by Telegraph correspondent Rob Crilly criticizing the film Zero Dark Thirty "for getting its facts wrong about the CIA vaccination campaign that sought to confirm the DNA of Osama bin Laden's children," development blogger Tom Murphy writes in the Humanosphere blog, "Crilly's larger point is to say that the film gives further ammo to polio vaccine conspiracy theorists."

CELF6 genetic mutation may underlie common behaviors seen in people with autism

Scientists at Washington University School of Medicine in St. Louis have identified a genetic mutation that may underlie common behaviors seen in some people with autism, such as difficulty communicating and resistance to change.

Tousled-like kinases play a key role in suppression and activation of herpesviruses

Kaposi's sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV) hide within the worldwide human population. While dormant in the vast majority of those infected, these active herpesviruses can develop into several forms of cancer.

Ability to tune gene activity will permit refined research for drug resistance, cancer

Scientists who built a synthetic gene circuit that allowed for the precise tuning of a gene's expression in yeast have now refined this new research tool to work in human cells, according to research published online in Nature Communications.
