Baker’s yeast could help in finding disease-causing mutations

It's easier than ever to sequence our DNA, but doctors still can't exactly tell from our genomes which diseases might befall us. Professor Fritz Roth is setting out to change this by going to basics -- to our billion-year-old cousin, baker's yeast.

LMU-led researchers define previously unknown signaling pathway that triggers inflammation

Using a combination of newly developed methods, researchers led by Ludwig-Maximilians-Universitaet (LMU) in Munich immunologist Veit Hornung have defined a previously unknown pathway that triggers inflammation.

Scientists identify gene associated with cleft lip and palate

Leading scientists have identified an important gene that is associated with cleft lip and palate.Experts say the discovery is a step closer to understanding how this birth defect arises, and will help in the development of medical approaches to prevent the disfiguring condition.

Research shows tumor suppressor protein regulates polarity genes

What does Brad Pitt have in common with a fruit fly? His Hollywood hairstyles cover a prominent cowlick - the swirl of hair that that is caused by a patterning mechanism also active in our two-winged friends -- that similarly feature "polarized" hair patterns.

Caltech researchers identify gene that causes severe insomnia when overactivated

Caltech biologists have performed the first large-scale screening in a vertebrate animal for genes that regulate sleep, and have identified a gene that when overactivated causes severe insomnia. Expression of the gene, neuromedin U (Nmu), also seems to serve as nature's stimulant--fish lacking the gene take longer to wake up in the morning and are less active during the day.

Northwestern researchers use fruit fly genetics to understand how things may go wrong in cancer

Cancer cells are normal cells that go awry by making bad developmental decisions during their lives. In a study involving the fruit fly equivalent of an oncogene implicated in many human leukemias, Northwestern University researchers have gained insight into how developing cells normally switch to a restricted, or specialized, state and how that process might go wrong in cancer.

New GSA e-book provides detailed overviews of aging process across multiple organisms

A new e-book published by The Gerontological Society of America provides a primary resource for detailed overviews of the aging process across multiple organisms -- from microbes to humans. This seminal publication, "Molecular and Cellular Biology of Aging," is intended as a textbook for emerging scholars of all levels.

New CRC aims to better understand autophagy at molecular and cellular level

The German Research Foundation (Deutsche Forschungsgemeinschaft/DFG) has approved 11 M € for the next four years for establishing a CRC on selective autophagy under the lead of Goethe University. Autophagy literally means "self-eating" and refers to a sophisticated system in which cellular waste is specifically detected and removed.

CRISPR-Cas9 can help knock out genes in exotic animals

The simplicity of CRISPR-Cas9 gene editing will soon make studying the genes of any organism, from the simplest slime mold to the octopus, as easy as it now is to study the genes controlling development in standard lab animals such as nematodes, fruit flies, frogs and mice.

Human heart can fully recover after massive damage

The scientists report the case of a newborn that had suffered a massive heart attack in the first hours of life. It was caused by a blockage in a vital coronary vessel. "The baby's heart was severely damaged. Astonishingly, the baby recovered very quickly," said Bernhard Haubner, a cardiologist and researcher, and his colleague, Johanna Schneider, in an article just published in the journal "Circulation Research".

Dopamine measurements provides information crucial for human choice

Virginia Tech Carilion Research Institute scientists have reported measurements of dopamine release with unprecedented temporal precision in the brains of people with Parkinson's disease. The measurements, collected during brain surgery as the conscious patients played an investment game, demonstrate how rapid dopamine release encodes information crucial for human choice.

Researchers develop multiplexed screening approach to study cancer development in mice

In a novel use of the CRISPR/Cas9 system, which can be deployed to switch genes off, researchers from Germany, the UK and Spain have developed a multiplexed screening approach to study and model cancer development in mice. The scientists mutated genes in the adult mouse liver uncovering their cancer-causing roles and determining which combinations of genes cooperate to cause liver cancer.

UCSF researchers map genetic signature of unusual stem cells in the human brain

The human cerebral cortex contains 16 billion neurons, wired together into arcane, layered circuits responsible for everything from our ability to walk and talk to our sense of nostalgia and drive to dream of the future. In the course of human evolution, the cortex has expanded as much as 1,000-fold, but how this occurred is still a mystery to scientists.

Researchers discover new strategy for attacking cancer cells

University of Virginia School of Medicine researchers have discovered a new strategy for attacking cancer cells that could fundamentally alter the way doctors treat and prevent the deadly disease.

UVA researchers identify new strategy for attacking cancer cells

University of Virginia School of Medicine researchers have discovered a new strategy for attacking cancer cells that could fundamentally alter the way doctors treat and prevent the deadly disease. By more selectively targeting cancer cells, this method offers a strategy to reduce the length of and physical toll associated with current treatments.

Johns Hopkins scientists develop novel fish embryo technique to identify potential new treatments for diabetes

In experiments with 500,000 genetically engineered zebrafish embryos, Johns Hopkins scientists report they have developed a potentially better and more accurate way to screen for useful drugs, and they have used it to identify 24 drug candidates that increase the number of insulin-producing cells in the pancreas.

University of Southampton research finds that electric fields alter behaviour of fruit flies

A new piece of research led by the University of Southampton has found that the behaviour of fruit flies, which are commonly used in laboratory experiments, is altered by electric fields.

Recipients of GSA poster awards announced at 20th International C. elegans Meeting

The Genetics Society of America and the C. elegans research community are pleased to announce the recipients of the GSA poster awards at the 20th International C. elegans Meeting, which took place at the University of California, Los Angeles, June 24-28, 2015.

Gene responsible for cancer growth plays unexpected role in prostate cancer

A gene that is responsible for cancer growth plays a totally unexpected role in prostate cancer. The gene Stat3 is controlled by the immune modulator interleukin 6 and normally supports the growth of cancer cells. The international research team led by Prof. Lukas Kenner from the Medical University of Vienna, the Veterinary University of Vienna, and the Ludwig Boltzmann Institiute for Cancer Research (LBI-CR) discovered a missing link for an essential role of Stat3 and IL-6 signalling in prostate cancer progression.

Study on fruit flies, brewer's yeast may provide clues about cause of Spinal Muscular Atrophy

Scientists at the University of Malta and the Institut de Génétique Moléculaire de Montpellier (CNRS/Université de Montpellier) have shown that fruit flies and brewer's yeast can reveal clues about the cause of Spinal Muscular Atrophy (SMA), the most common genetic killer of infants.
