New molecular mechanism involved in the regulation of cholesterol movement in cells found

Researchers from the University of Barcelona and the August Pi i Sunyer Biomedical Research Institute found a new molecular mechanism involved in the regulation of the cholesterol movement in cells, an essential process for a proper cell functioning.

New automated method helps identify cancer cell metabolism inhibitors

UCLA Jonsson Comprehensive Cancer Center researchers have developed a new automated method for testing hundreds of molecules at a time to find out which ones block cancer cells from consuming glucose - the sugars they need to spread and grow.

Gene discovery in fruit flies could provide clues to counteract mitochondrial diseases

Scientists have identified a protein in fruit flies that can be targeted to reverse the effects of disease-causing mutations in mitochondrial genes. The discovery could provide clues about how to counteract human mitochondrial diseases, for which there is currently no cure.

UCLA scientists discover link between a protein and human blood stem cell self-renewal

UCLA scientists have discovered a link between a protein and the ability of human blood stem cells to self-renew. In a study published today in the journal Nature, the team reports that activating the protein causes blood stem cells to self-renew at least twelvefold in laboratory conditions.

Over €12 million funding to advance autophagy research

Four years ago, Collaborative Research Centre (CRC) 1177 on selective autophagy was established under the leadership of Goethe University - now the German Research Foundation has given the green light for its further funding.

Potential new treatment for mitochondrial diseases discovered from fruit fly genes

Researchers have discovered a way to reverse the impact of disease-causing mitochondrial mutations by targeting fruit fly gene.

What protects killer T cells from accidental death?

White blood cells, which release a toxic potion of proteins to kill cancerous and virus-infected cells, are protected from any harm by the physical properties of their cell envelopes, find scientists from UCL and the Peter MacCallum Cancer Centre in Melbourne.

Hibernators reveal genetic clues to better understand and treat obesity, metabolic disorders

Hibernation is one of nature's strangest quirks, inducing bears and other mammals to pack on massive weight- amounts that would be unhealthy for humans - so they can survive months of slumber. Yet when these animals reemerge, they are as fit as ever.

Study points to two types of motion that keeps cells in shape

The health of cells is maintained, in part, by two types of movement of their nucleoli, a team of scientists has found. This dual motion within surrounding fluid, it reports, adds to our understanding of what contributes to healthy cellular function and points to how its disruption could affect human health.

Study shows how fiber spacing could control cell sticking

Researchers from the Mechanobiology Institute at the National University of Singapore have shown that cells can attach to the fibrous protein meshwork that surrounds them only if the fibers are spaced close enough.

Stem cells do not take the day off on national holidays

While most of us are stuffing ourselves with turkey and pumpkin pie at home on Thanksgiving Day, the staff at one Cedars-Sinai laboratory will be on the job, feeding stem cells.

Enzyme caspase-8 controls apoptosis, necroptosis and pyroptosis

The enzyme caspase-8 induces a molecular cell death programme called pyroptosis without involving its enzymatic activity, a new study by Hamid Kashkar published in Nature shows.

Research shows how cilia and exocyst contribute to extracellular vesicle production

Although the cilium has been known to scientists for more than 100 years, it is only recently that it has been acknowledged to play important roles in physiology.

Scientists record assembly of ribosomes in real time

A team of scientists from Scripps Research and Stanford University has recorded in real time a key step in the assembly of ribosomes--the complex and evolutionarily ancient "molecular machines" that make proteins in cells and are essential for all life forms.

DNA-modulated liquid droplets may explain how prion proteins clump

Researchers at the Federal University of Rio de Janeiro, in Brazil, have identified that the interaction between prion proteins and DNA may be behind the formation of protein amyloid aggregates and of the emergence of neurodegenerative diseases such as Creutzfeldt-Jakob disease and other spongiform encephalopathies.
