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).

Berkeley Lab researchers unveil analytical technique for easy comparisons of proteins in solution

A revolutionary X-ray analytical technique that enables researchers at a glance to identify structural similarities and differences between multiple proteins under a variety of conditions has been developed by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory.

Revised criteria improve early-onset dementia diagnosis

Updated diagnostic criteria based on the Frontotemporal Dementia Consensus are “encouragingly” sensitive and specific in identifying patients who have early-onset dementia, a study finds.

Skin cancer may increase subsequent primary malignancy risk

Research suggests that people with non-melanoma skin cancer are at moderately increased risk for developing other primary malignancies in the future, particularly breast and lung cancer and melanoma.

New methods boost researchers' analytical powers by incorporating prior knowledge about SNPs function

As scientists probe and parse the genetic bases of what makes a human a human (or one human different from another), and vigorously push for greater use of whole genome sequencing, they find themselves increasingly threatened by the unthinkable: Too much data to make full sense of.

CNIO researcher captures panoramic photo of proteins that take part in human DNA replication

The Genomic Instability Group led by researcher -scar Fern-ndez-Capetillo at the Spanish National Cancer Research Centre (CNIO), has for the first time obtained a panoramic photo of the proteins that take part in human DNA division, a process known as replication.

Network of genes is a crucial mechanism driving Late Onset Alzheimer's Disease

Scientists from the Icahn School of Medicine at Mount Sinai, in collaboration with researchers from Icelandic Heart Association, Sage Bionetworks, and other institutions, have discovered that a network of genes involved in the inflammatory response in the brain is a crucial mechanism driving Late Onset Alzheimer's Disease (LOAD).

Researchers discover gene that can cause 3 different diseases depending on its alteration

An international research consortium led by the Universitat Aut-noma de Barcelona (UAB), the CIBERER and the University of Wurzburg (Germany) has discovered a gene that can cause three totally different diseases, depending on how it is altered.

Study: Blocking certain enzymes in cell may prevent cancer cell division and growth

Blocking certain enzymes in the cell may prevent cancer cell division and growth, according to new findings from researchers at the Graduate School of Biomedical Sciences at the Icahn School of Medicine at Mount Sinai.

Study reveals a new way for detecting colorectal cancers

A unique new study led by University of Kentucky Markey Cancer Center researchers Guo-Min Li and Libya Gu, in collaboration with Dr. Wei Yang at National Institutes of Health, reveals a novel mechanism explaining the previously unknown root cause of some forms of colorectal cancers.

Research on miRNAs offers new therapeutic potential to fight diseases

RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene regulation and, in the process, impact almost all biological processes - from development to physiology to stress response.

New technologies speed health care delivery, reduce costs, pioneer new therapies

The current special issue of Technology and Innovation - Proceedings of the National Academy of Inventors, devoted to studies on medical technology and health care delivery, focuses on a wide range of topics, from new technologies to reduce the cost of health care to understanding the human microbiome.

New hope for patients with chronic HBV infection

Exciting new data presented today at the International Liver Congress- 2013 include rults from early in vitro and in vivo studies targeting covalently closed circular DNA (cccDNA), which may form the basis of a cure for chronic hepatitis B virus (HBV) infection.

Mayo Clinic earns No. 6 position on 2013 DiversityInc Top 10 Hospital System list

Mayo Clinic has been ranked No. 6 on the 2013 DiversityInc Top 10 Hospital System for its ongoing commitment to diversity and inclusion.

Hospital for Special Surgery receives grant for new genomics center to study autoimmune diseases

Hospital for Special Surgery in New York City has received a $5.6 million grant from The Tow Foundation to establish the Hospital for Special Surgery Genomics Center.

Individual hydroxymethylcytosine molecules in DNA detected by new method involving chemical modification and nanopore analysis

Changes in the bases that make up DNA act as markers, telling a cell which genes it should read and which it shouldn’t. In the journal Angewandte Chemie, a British team has now introduced a new method that makes it possible to enrich the rare gene segments that contain the modified base hydroxymethylcytosine and to identify individual hydroxymethylcytosine molecules in DNA. Such modifications are associated with autoimmune diseases and cancer.

Methodist Hospital will soon have new brain and pituitary tumor treatment center

Brain and pituitary tumor patients will soon have access to a state-of-the-art facility at The Methodist Hospital, a result of a $10 million dollar commitment from a Houston oil executive.

University of Leicester study investigates early detection of pancreatic cancer

Pioneering research to investigate whether pancreatic cancer can be detected early through a blood test is to be spearheaded by the University of Leicester thanks to new funding provided by Hope Against Cancer.

Research shows sophisticated genetic circuits allow individual bacterium to act on its own

Individual freedom and social responsibility may sound like humanistic concepts, but an investigation of the genetic circuitry of bacteria suggests that even the simplest creatures can make difficult choices that strike a balance between selflessness and selfishness.

Researchers find deficiency in anti-tumor protein can delay DNA repair after radiation treatment

Researchers at Moffitt Cancer Center have found that a deficiency in an important anti-tumor protein, p53, can slow or delay DNA repair after radiation treatment. They suggest that this is because p53 regulates the expression of two enzymes (JMJD2b and SUV39H1) that control the folding of DNA.

World must be better prepared for potential pandemics

"In China an influenza virus never before seen in people had, as The Economist went to press, infected at least 82 and killed 17. Meanwhile a new type of coronavirus, the family that brought severe acute respiratory syndrome (SARS), is festering in the Middle East," an editorial in the magazine states.
