Study uncovers new DNA sequences in Swedish genomes

People - or more specifically just Swedes - are more like chimpanzees than previously known. This is indicated in a genetic mapping of one thousand Swedish individuals, where new DNA sequences that should be included in the reference genome have been identified.

Discovery provides potential therapeutic target for prostate cancers with PTEN mutation

PTEN, a tumor suppressor gene mutated in approximately 20% of primary prostate cancers, and in as many as 50% of androgen deprivation-resistant prostate cancers, relies on another gene, ARID4B, to function.

Faster, cheaper, better: improved gene therapy tool production

The heart of modern therapy is increasingly personalized and targeted at specific cellular or genetic deficits. This requires gene therapy, in many cases. A new study, published on 19 September 2019 in the journal Nature, describes an improved way to produce purified gene carrier viruses called AAVs cheaply and quickly, from the culture medium.

Genetic mutation appears to help people fight off MRSA

Researchers have discovered that people who carry a certain genetic mutation may have a greater chance of fighting off MRSA infections.

5 million gift will help create Edward P. Evans Center for MDS at Dana-Farber

A $5 million gift from the Edward P. Evans Foundation will create the Edward P. Evans Center for Myelodysplastic Syndromes at Dana-Farber Cancer Institute.

Inherited genetic tendency appears to protect people from MRSA infections

An inherited genetic tendency appears to increase the likelihood that a person can successfully fight off antibiotic-resistant staph infections, according to a study led by Duke Health researchers.

Cure for Rett Syndrome a step closer as scientists successfully reactivate 'back-up’ genes

A team headed by Vincent Pasque at his Lab at KU Leuven alongside researchers from the Jean-Christophe Marine lab and the Edith Heard lab have made a significant step towards developing a treatment for Rett syndrome and other X chromosome linked disorders.

Biologists observe how microtubules branch in new directions in animal cells

Cell biologist Thomas Maresca and senior research fellow Vikash Verma at the University of Massachusetts Amherst say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged in cellular extracts and plant cells but not directly observed in animal cells.

Gene coding error likely responsible for rare form of inherited 'short telomere' disease

By combing through the entire genetic sequences of a person with a lung scarring disease and 13 of the person’s relatives, Johns Hopkins Medicine researchers say they have found a coding error in a single gene that is likely responsible for a rare form of the disease and the abnormally short protective DNA caps on chromosomes long associated with it.

Salk researchers develop method to reveal epigenetic features of brain cells

The brain's prefrontal cortex, which gives us our ability to solve problems and plan ahead, contains billions of cells. But understanding the large diversity of cell types in this critical region, each with unique genetic and molecular properties, has been challenging.

Researchers investigate how to prevent the onset of schizophrenia using mouse model

Although predisposing processes occur earlier, schizophrenia breaks out at young adulthood, suggesting it might involve a pathological transition during late brain development in predisposed individuals.

Researchers find synergistic connection between two deadly blood-clotting diseases

Two rare but potentially deadly blood-clotting diseases, namely thrombotic thrombocytopenic purpura, or TTP, and hemolytic uremic syndrome, or HUS, show similar pathologies -- a multitude of painful blockages in small blood vessels that cause varying degrees of organ injury throughout the body. However, the two disorders have distinct biological mechanisms.

Lefthandedness genes change the way the brain develops

A new study has discovered four genes related to left-handedness, and the associated differences in the way the brain is organized. About a tenth of people are left-handed, making this a not uncommon trait. However, the new findings point to greater verbal fluency with this alternate version of the brain, compared to right-handedness.

How tuberculosis progresses: genetic factors play a major role

There are almost 1.8 billion people with tuberculosis bacilli in their body, but only about 5% to 15% develop overt infection, usually within 18 months of initial exposure. The reason behind this selective progression has been sought for decades by scientists from a variety of fields.

Large-scale study maps the genetic underpinnings of early TB progression

While the vast majority of the 1.8 billion people infected with the TB bacterium never experience active disease, an estimated 5 to 15 percent do develop full-blown infections--roughly half of them within 18 months of exposure.

Researchers map uncharted area of genome using advanced imaging

Using advanced imaging techniques, researchers at the University of Colorado Anschutz Medical Campus have mapped a previously uncharted region of the human genome that gives rise to a variety of disease, setting the stage to potentially test for the conditions in the future.

Presence of XX sex chromosomes increases risk of heart attacks and coronary artery disease

New research at the University of Kentucky has confirmed that the presence of XX sex chromosomes increases the amount of fat circulating in the blood, which leads to narrowing of the arteries and ultimately a higher risk of heart attacks and coronary artery disease.

Large study quashes idea of “gay gene”

A vast new study including almost half a million people has concluded that no single gene is associated with same-sex behavior.

DNA methylation closely linked to telomere length

Aging is associated with multiple disease conditions. Recently it has been found that many of these illnesses are linked to the length of the telomeres at the ends of every chromosome. Telomere length (TL) is affected by both genetic and epigenetic contributions.

Sick mitochondria pollute the cells, cause telomere damage

Researchers at UPMC Hillman Cancer Center provide the first concrete evidence for the long-held belief that sick mitochondria pollute the cells they're supposed to be supplying with power.
