DNA News and Research

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 gene predicts HCV interferon response

Researchers have discovered a gene which interferes with the clearance of hepatitis C virus infection.

JAMA column outlines need for frozen, larger specimens in DNA-sequencing era

Genetic sequencing technology is altering the way cancer is diagnosed and treated, but traditional specimen handling methods threaten to slow that progress.

UCSB scientists publish groundbreaking study results of Type 2 diabetes

While legions of medical researchers have been looking to understand the genetic basis of disease and how mutations may affect human health, a group of biomedical researchers at UC Santa Barbara is studying the metabolism of cells and their surrounding tissue, to ferret out ways in which certain diseases begin.

Researchers identify four new genetic regions associated with Behcet's disease

Researchers have identified four new regions on the human genome associated with Behcet's disease, a painful and potentially dangerous condition found predominantly in people with ancestors along the Silk Road.

TRIP-Br2 plays a major role in energy metabolism and fat storage

As part of their ongoing research on the physiologic factors that contribute to the development of obesity, Joslin Diabetes Center scientists have identified a cell cycle transcriptional co-regulator - TRIP-Br2 - that plays a major role in energy metabolism and fat storage.

Study reveals large microbial diversity in breast milk

Spanish researchers have traced the bacterial microbiota map in breast milk, which is the main source of nourishment for newborns. The study has revealed a larger microbial diversity than originally thought: more than 700 species.

ParoChip can allow dentists to quickly detect and analyze periodontitis pathogens

Bleeding gums during tooth brushing or when biting into an apple could be an indication of periodontitis, an inflammatory disease of the tissues that surround and support the teeth. Bacterial plaque attacks the bone, meaning teeth can loosen over time and in the worst case even fall out, as they are left without a solid foundation to hold them in place.

Stanford scientists identify molecular basis for hypertrophic cardiomyopathy

When a young athlete dies unexpectedly on the basketball court or the football field, it's both shocking and tragic. Now Stanford University School of Medicine researchers have, for the first time, identified the molecular basis for a condition called hypertrophic cardiomyopathy that is the most common cause for this type of sudden cardiac death.

PSCA gene’s rs2294008 variant on T nucleotide may increase risk of bladder cancer

Patients who have inherited a specific common genetic variant develop bladder cancer tumors that strongly express a protein known as prostate stem cell antigen (PSCA), which is also expressed in many pancreatic and prostate tumors, according to research at the National Institutes of Health.

Chromatin regulation not governed by a uniform histone code

In a novel use of gene knockout technology, researchers at the University of California, San Diego School of Medicine tested the same gene inserted into 90 different locations in a yeast chromosome - and discovered that while the inserted gene never altered its surrounding chromatin landscape, differences in that immediate landscape measurably affected gene activity.

New technique can precisely add or delete genes in living cells

Researchers at MIT, the Broad Institute and Rockefeller University have developed a new technique for precisely altering the genomes of living cells by adding or deleting genes.

Trovagene, MD Anderson partner to detect transrenal BRAF mutations in metastatic cancers

Trovagene, Inc., a developer of transrenal molecular diagnostics, announced that it has entered into a clinical collaboration with The University of Texas MD Anderson Cancer Center to detect transrenal BRAF mutations in the urine of patients with advanced or metastatic cancers.

Prenatal brain development may be important influence on psychiatric risk later in life

Some brain changes that are found in adults with common gene variants linked to disorders such as Alzheimer's disease, schizophrenia, and autism can also be seen in the brain scans of newborns.

Sexual revolution effect may be hiding true extent of HPV prevalence

Human papillomavirus infection in older women is commonly due to reactivation of latent disease rather than new infection, research indicates.

DNA adducts linked to oral cancer in smokers

Having a high susceptibility to certain types of DNA damage caused by tobacco smoking could significantly increase the risk for oral cancer, show results of a Taiwanese study.

Researchers study response of living cells to artificial protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques-collectively referred to as synthetic biology-have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

New light on how epigenetic signals may function together to determine fate of stem cell

Long-standing research efforts have been focused on understanding how stem cells, cells capable of transforming into any type of cell in the body, are capable of being programmed down a defined path to contribute to the development of a specific organ like a heart, lung, or kidney. Research from the University of North Carolina at Chapel Hill School of Medicine has shed new light on how epigenetic signals may function together to determine the ultimate fate of a stem cell.
