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.

Validation of new method for studying how different drugs interact in the body

Scientists at Oregon State University may have proven how much people love coffee, tea, chocolate, soda and energy drinks as they validated their new method for studying how different drugs interact in the body.

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.

Air pollution associated with increased risk of deaths in Canada

Air pollution - even at levels below national and international air quality guidelines - is associated with an increased risk of deaths in Canada, according to new UBC research.

Discovery in C. difficile biology opens new window to developing treatments for dangerous infections

A process called sporulation that helps the dangerous bacterium Clostridium difficile (C. difficile) to survive inhospitable conditions and spread is regulated by epigenetics, factors that affect gene expression beyond the DNA genetic code, researchers at the Icahn School of Medicine at Mount Sinai report.

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.

Article reveals new mechanism of programmed aging

Nature has sentenced humans to an inevitable death from the time of birth; the natural instrument of execution is the aging process. According to modern scientific notions, only two root causes of aging can be: stochastic physiological damage or the implementation of a special genetic program in the body.

New partnership aims to explore, cultivate innovations in cell and gene therapy

Some patients who have not responded to traditional medicines are now experiencing remarkable recoveries thanks to next-generation immunotherapies. These therapies equip a patient's own immune cells to recognize, target, and destroy cancer cells.

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.

Scientists investigate the dynamics of molecular changes in gliomas

Until relatively recently, cancer was viewed as a single disease with sub-types based on where in the body it arose.

Wound healing events in mucous tissues could guard against AIDS

Wound healing events in mucous tissues during early infection by Simian Immunodeficiency Virus, or SIV, guard some primate species against developing AIDS, a recent study has learned.

Extra DNA scooped up alongside cancer-causing genes helps drive tumor growth

One of the ways a cancer-causing gene works up enough power to turn a normal cell into a cancer cell is by copying itself over and over, like a Xerox machine.

Doughnut-shaped circles of ecDNA provide tumor cells with a malignant twist

Deoxyribonucleic acid or DNA encodes information, not only in its sequence but also in its shape.

Researchers develop breakthrough in marine sponge cell culture

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for many organisms, including freshwater and terrestrial invertebrates.
