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).

UC Santa Barbara neuroscientists uncover mechanism of Alzheimer's progression

Medical research has yet to discover an Alzheimer's treatment that effectively slows the disease's progression, but neuroscientists at UC Santa Barbara may have uncovered a mechanism by which onset can be delayed by as much as 10 years.

New NIH grants support research that combines DNA sequence information and electronic medical records

A dozen awards from the National Institutes of Health will support research that incorporates DNA sequence information into electronic medical records. The goal of research conducted by the Electronic Medical Records and Genomics (eMERGE) network is to better understand the genomic basis of disease and to tailor medical care to individual patients based on their genomic differences.

Altering protein recycling complexes in human cells may help overcome chemotherapy resistance

Altering the protein recycling complexes in human cells, including cancer cells, allows the cells to resist treatment with a class of drugs known as proteasome inhibitors, according to Whitehead Institute scientists.

U-M study suggests potential treatment options for children with aggressive, advanced cancer

For children with rare, aggressive and advanced cancer, precision medicine may help doctors determine their best treatment options, a new study finds.

PRESTIGE study suggests novel target to prevent stent thrombosis

Recruitment of leukocytes is a hallmark of stent thrombosis, according to results from the PRESTIGE study presented today at ESC Congress and published in European Heart Journal. The findings suggest that immune cell mediated thrombotic processes may be a realistic target for novel therapies to prevent stent thrombosis.

Benznidazole has significant antiparasitic activity, but does not reduce progression of Chagas cardiomyopathy

A 40 to 80 day treatment with the antiparasitic medication benznidazole significantly reduced parasite activity in the blood, but not progression, of serious heart problems over a 5-year period among patients with established Chagas disease (CD) cardiomyopathy, results of the BENEFIT trial show.

UCSF-led team develops new technique to create tiny models of human tissues

A UCSF-led team has developed a technique to build tiny models of human tissues, called organoids, more precisely than ever before using a process that turns human cells into a biological equivalent of LEGO bricks. These mini-tissues in a dish can be used to study how particular structural features of tissue affect normal growth or go awry in cancer. They could be used for therapeutic drug screening and to help teach researchers how to grow whole human organs.

Gene ZSCAN4 may help treat Down syndrome

For people with Down syndrome, news from Elixirgen, LLC may brighten their day. The biotechnology company, located in the Science + Technology Park at Johns Hopkins, has outlined one of the best potential therapies yet for people with Down syndrome and other chromosome disorders in a paper entitled, "Correction of Down syndrome and Edwards syndrome aneuploidies in human cell cultures," published in the journal DNA Research.

Scientists identify new protein that regulates severity of tissue damage caused by RA

Scientists have identified a new protein (C5orf30) which regulates the severity of tissue damage caused by rheumatoid arthritis (RA), an autoimmune disease that causes inflammation, pain, stiffness and damage to the joints of the feet, hips, knees, and hands.

ESC Guidelines recommend DNA analysis for post mortem assessment in young sudden death victims

ESC Guidelines published today recommend DNA analysis as a fundamental component of post mortem assessment in young sudden death victims. Identification of a genetic cause helps to quickly diagnose and protect relatives.

Fetal microchimerism could be a subtle and dizzyingly complex puzzle

Parents go to great lengths to ensure the health and well-being of their developing offspring. The favor, however, may not always be returned.

Researchers provide new insights into biology of aging, age-related diseases

The scientific team of a new biotech company Gero in collaboration with one of the leading academics in the field of aging Prof. Robert J. Shmookler Reis (current world record holder in life extension for model animals - 10 fold for nematodes) has recently brought new insights into biology of aging and age-related diseases, primarily, around the stability and stress resistance of certain gene regulatory networks.

Study provides clearer picture of evolutionary history, genetic organization of cannabis

A study by Canadian researchers is providing a clearer picture of the evolutionary history and genetic organization of cannabis, a step that could have agricultural, medical and legal implications for this valuable crop.

Researchers successfully use alcohols as reagents in alkylation reaction

Researchers at Princeton have developed a dual catalyst system that directly installs alkyl groups--fragments containing singly bonded carbon and hydrogen atoms that have extremely useful properties for drug discovery--onto compounds called heteroarenes. The new reaction uses simple and abundant alcohols and offers a milder and more widely applicable alternative to existing strategies.

Cell-to-cell transmission of HIV leads to development of AIDS

Researchers from the Gladstone Institutes have revealed that HIV does not cause AIDS by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another.

Researchers identify druggable target to potentially root out colon cancer, end relapse

Researchers targeting colorectal cancer stem cells - the root cause of disease, resistance to treatment and relapse - have discovered a mechanism to mimic a virus and potentially trigger an immune response to fight the cancer like an infection.

Scientists generate pluripotent stem cells with more stable genomes

Damaged tissue, such as pancreas, heart, and neuronal tissue, which is regenerated to treat cardiovascular diseases, diabetes, or neurodegenerative diseases. This is one of the ambitious scenarios to which regenerative medicine aspires and that is being announced as one of the great promises of twenty-first century biomedicine for the treatment of a long list of diseases affecting people today.

Researchers identify new virus that plays role in rare type of liver cancer

More than a cause of a simple infection, viruses are often involved in the development of serious diseases. Such is the case with liver cancer, which often develops in an organ that has been weakened by hepatitis B or C virus.
