Researchers discover ‘recycled’ genes in mammalian genome

One often hears about the multitude of genes we have in common with chimps, birds or other living creatures, but such comparisons are sometimes misleading. The shared percentage usually refers only to genes that encode instructions for making proteins -- while overlooking regulatory genes, which nonetheless make up a large part of the genome.

Lesser-known gene appears to play greater role in Alzheimer's and dementia-related memory decline

The notorious genetic marker of Alzheimer's disease and other forms of dementia, ApoE4, may not be a lone wolf.

Genome sequence cannot predict radiation resistance, say researchers

For the last two decades, researchers worldwide have been using whole genome sequencing to understand what makes cells radiation-resistant, hoping to solve an old biological mystery: why is it that one of the most radiation-resistant organisms, Deinococcus radiodurans, aka "Conan the bacterium," can survive hundreds of times more DNA damage caused by gamma rays than most other organisms? According to a study published recently in Standards of Genomic Sciences by researchers at the Uniformed Services University (USU), the amount of radiation a Deinococcus cell can survive in fact has little to do with the number and types of its DNA repair proteins.

Researchers develop model to explore hard-to-study mutations in human genome

A team of researchers led by a bioinformatician at the University of California San Diego has developed a method to help determine whether certain hard-to-study mutations in the human genome, called short tandem repeats or microsatellites, are likely to be involved in harmful conditions.

Penn researchers find abnormally shortened telomeres in young DMD patients’ muscle stem cells

Researchers from the Perelman School of Medicine at the University of Pennsylvania have made a discovery about muscular dystrophy disorders that suggest new possibilities for treatment.

Researchers find correlation between shorter telomeres and presence of heart failure

Each cell in the average human body contains 23 pairs of chromosomes, with four telomeres on each pair. Telomeres cover the end of the chromosome, protecting it from deterioration or fusion with adjacent chromosomes, much like the plastic tip at the end of a shoelace protects it from unraveling.

Split-brain study using fruit fly provides better understanding of autism

A better understanding of the cause of autism may come from an unlikely source, neurological studies of the fruit fly.

Japanese scientists uncover new genetic marker for schizophrenia

Schizophrenia is a complicated disease that often appears in early adulthood. Although scientists have not traced the genetic causes, more than 80% of schizophrenia cases are considered to have a hereditary cause.

UAB researchers reveal key role for RSF1 protein in silencing genes

A fertilized human egg develops into multiple tissues, organs and about 200 distinct cell types. Each cell type has the same genes, but they are expressed differently during development and in mature cells.

Human ancestors responsible for transmitting ancient strains of herpesvirus, study finds

An international study of integrated HHV-6 has discovered that a small number of human ancestors, one from about 24,000 years ago, have been responsible for transmitting ancient strains of the virus to individuals today - affecting about a million people in the UK alone.

Distinguishing biothreat look-alikes could aid biological surveillance

Biological "detectives" are tracking down biothreats such as the bacteria that causes tularemia ("rabbit fever"), but they constantly face the challenge of avoiding false positives.

Scientists develop new system to identify and characterize regulatory DNA sequences

Scientists from the Children's Medical Center Research Institute at UT Southwestern have developed an innovative system to identify and characterize the molecular components that control the activities of regulatory DNA sequences in the human genome.

New research suggests cell immortalization as more complicated process than originally thought

A mutation that helps make cells immortal is critical to the development of a tumor, but new research at the University of California, Berkeley suggests that becoming immortal is a more complicated process than originally thought.

Researchers develop and validate new assay that detects gene fusions in solid tumors

An assay that identifies a peculiar but important abnormality in cancer cells has been developed and validated by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Counteracting premature aging

Aging is the continuing process of such stress exposures, and with advancing age (normal aging), we must carry lots of senescent cells within our bodies. Senescent cells also often provide some ‘bad influences’ to surrounding healthy cells; such as chronic inflammation and tumorigenesis

Duke researchers map evolution of sex chromosomes in fungus linked to human disease

Biologically speaking, nearly every species on Earth has two opposite sexes, male and female. But with some fungi and other microbes, sex can be a lot more complicated.

Researchers unravel genetic characteristics that increase risk of developing Tourette syndrome

An international research team including Vasiliy Ramensky, a member of the MIPT Life Sciences Center, has unraveled genetic characteristics that increase the risk of developing Tourette syndrome.

Study supports genetic testing as first-line diagnostic method for young children with epilepsy

A study published in JAMA Pediatrics supports the use of genetic testing, especially with sequencing, as first-line diagnostic method for young children with seizures.
