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).

New DNA-delivering film holds promise for improving effectiveness of vaccines

Vaccines usually consist of inactivated viruses that prompt the immune system to remember the invader and launch a strong defense if it later encounters the real thing. However, this approach can be too risky with certain viruses, including HIV.

Research reveals the mechanism of epigenetic reprogramming

New research reveals a potential way for how parents' experiences could be passed to their offspring's genes.

Researchers identify cancer-associated mutations

Two new mutations that collectively occur in 71 percent of malignant melanoma tumors have been discovered in what scientists call the "dark matter" of the cancer genome, where cancer-related mutations haven't been previously found.

Genome sequencing data gives important clues on cancer

Genome sequencing data once regarded as junk is now being used to gain important clues to help understand disease.

New study may help treat patients with multiple myeloma

A study led by Robert G. Hawley, Ph.D., professor and chair of the department of anatomy and regenerative biology at the George Washington University (GW) School of Medicine and Health Sciences (SMHS), may help predict which patients with multiple myeloma will respond better to certain treatments.

Flow cytometry can now be used for quantification of microbial cells in drinking water

Flow cytometry (FCM) can now be officially used for the quantification of microbial cells in drinking water. The new analytical method - developed at Eawag and extensively tested both in Switzerland and abroad - has been incorporated into the Swiss Food Compendium (SLMB) by the Federal Office of Public Health (FOPH).

Researchers to develop new diagnostic tools and treatments for people with rare diseases

A multi-million Euro initiative is bringing together researchers from across the world to develop new diagnostic tools and new treatments for people with rare diseases and to connect research data in this area on a global scale.

Researchers discover safe and efficient way to get large molecules through the cell membrane

Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells.

Mice with reduced caloric intake accumulate longer telomeres

One of the indicators of a cell's health is the state of its DNA and containers-the chromosomes-so when these fuse together or suffer anomalies, they can become the source of illnesses like cancer and/or ageing processes.

World Cancer Day to focus on awareness and prevention, importance of research

Cancer takes the lives of some 7.6 million people worldwide each year, according to the World Health Organization. And while the upcoming World Cancer Day will focus on a global message of cancer awareness and prevention, the importance of cancer research also will resonate.

Scientists identify consistent epigenetic signatures in men with metastatic prostate cancer

In a genome-wide analysis of 13 metastatic prostate cancers, scientists at the Johns Hopkins Kimmel Cancer Center found consistent epigenetic "signatures" across all metastatic tumors in each patient.

Salk Institute to establish Helmsley Center for Genomic Medicine

The Salk Institute for Biological Studies has received a $42 million gift-the largest in the Institute's history-to establish the Helmsley Center for Genomic Medicine (HCGM), a research center dedicated to decoding the common genetic factors underlying many complex chronic human diseases.

SMO and AKT1 mutations appear to drive about 15% of meningiomas

Large-scale genomic sequencing has revealed two DNA mutations that appear to drive about 15 percent of brain tumors known as meningiomas, a finding that could lead to the first effective drug treatments for the tumors, report scientists from Dana-Farber Cancer Institute and the Broad Institute.

Novel way to engineer specialized immune cells targeted by the AIDS virus

Researchers at the Stanford University School of Medicine have found a novel way to engineer key cells of the immune system so they remain resistant to infection with HIV, the virus that causes AIDS.

SV Bio, Mayo Clinic partner on whole genome diagnostics and interpretation

Mayo Clinic and Silicon Valley Biosystems (SV Bio) today announced a strategic collaboration for whole genome diagnostics and interpretation at the Mayo Clinic Center for Individualized Medicine and Mayo Medical Laboratories.

Very low levels of BPS can disrupt natural estrogen hormone actions

A few years ago, manufacturers of water bottles, food containers, and baby products had a big problem. A key ingredient of the plastics they used to make their merchandise, an organic compound called bisphenol A, had been linked by scientists to diabetes, asthma and cancer and altered prostate and neurological development.

SLU team discovers molecular pathway that contributes to triple-negative breast cancer

In research published in the Jan. 17 issue of The Journal of Cell Biology, a team led by Susana Gonzalo, Ph.D., assistant professor of biochemistry and molecular biology at Saint Louis University, has discovered a molecular pathway that contributes to triple-negative breast cancer, an often deadly and treatment resistant form of cancer that tends to strike younger women.

ParseCNV software can detect disease-causing copy number variations

A novel software tool, developed at The Children's Hospital of Philadelphia, streamlines the detection of disease-causing genetic changes through more sensitive detection methods and by automatically correcting for variations that reduce the accuracy of results in conventional software.
