Damaged powerhouses of cells can self-repair in a kind of workshop mode

If the energy supply of a cell is disturbed by damage, it can protect itself from functional losses and repair itself in a kind of workshop mode.

New study overturns ‘snapshot’ model of cell cycle accepted since 1974

Cells have a big decision: Should they replicate or sleep? Healthy cells can go either way. Cancer cells' replication switches are stuck in the 'on' position.

Extracellular forces regulate the formation of epithelia-integrating actomyosin bundles

Different surfaces and organs of the body are covered by epithelial tissue, which is composed of cells tightly connected to each other.

Researchers uncover novel role for autophagy in the brain

Scientists from the laboratory of Dr. Natalia Kononenko at the CECAD Center of Excellence in Aging Research at the University of Cologne have found out that autophagy - the process of cellular self-recycling, or waste clearance - is dispensable for the survival of the neurons in mice.

Scientists unravel a new mechanism that triggers cell death and inflammation

Z-form nucleic acids are double-stranded DNA and RNA molecules with an unusual left-handed double helix structure, as opposed to the classical right-handed Watson-Crick double helix. Z-nucleic acids were discovered more than 40 years ago, but their biological function has remained poorly understood.

Amyloid plaque formation causes brain tissue loss in animals

Amyloid plaque formation directly causes brain tissue loss in animals, but a drug called lithium reduces the life-shortening effects of this loss, shows a study published today in eLife.

Combination of exercise and cell-aging drug could help people with chronic inflammatory myopathy

Exercise can only improve strength in muscle-degenerating diseases when a specific type of muscle cell ages, report a Hokkaido University researcher and colleagues with Sapporo Medical University in Japan. Their findings utilizing mice models were published in the journal Nature Communications.

Novel immunotherapy eradicates solid tumors in mice without adverse side effects

Scientists have developed a new immunotherapy that eradicates solid tumors in mice without adverse side effects, according to a new study published today in eLife.

New microfluidic chip can mimic hypoxic conditions after a heart attack

Researchers led by biomedical engineers at Tufts University invented a microfluidic chip containing cardiac cells that is capable of mimicking hypoxic conditions following a heart attack - specifically when an artery is blocked in the heart and then unblocked after treatment.

Study reveals new mechanism underlying organelle communication in brown fat cells

In recent years, brown fat has garnered increasing attention as the so-called good fat that can protect against obesity and associated health risks, like cardiovascular disease and diabetes.

Researchers discover new way to refine production of retinal cells to treat blindness

Researchers at Karolinska Institutet and St Erik Eye Hospital in Sweden have discovered a way to refine the production of retinal cells from embryonic stem cells for treating blindness in the elderly.

Jumping genes help make functional brain cells in a lab dish

The process of making functional brain cells in a lab dish requires the precise activation of selfish genetic elements known as LINE-1 (L1) retrotransposons.

Scientists unravel mystery about how nature can access genetic information in cells

Australian scientists have unraveled part of the mystery about how nature can usefully access genetic information in cells despite it being so tightly packed away.

Targeting critical enzyme for sperm formation could help address male infertility

While some of our body's cells divide in a matter of hours, the process of making sperm, meiosis, alone takes about 14 days from start to finish. And fully six of those days are spent in the stage known as the pachytene, when pairs of chromosomes from an individual's mother and father align and connect.

Researchers investigate how cellular protein shredders can be programmed to fight cancer

An international team of researchers led by the Universities of Bonn and Ulm has investigated how a cell's own "protein shredder" can be specifically programmed to fight cancer.

New molecular probes to study the behavior of opioid receptors

It could be an important step forward in the improvement of pain therapy: Thanks to newly developed molecular probes, the behavior of individual opioid receptors can now be studied in detail.

Changes in surface sugarlike molecules help cancer cells to spread

Changes in a specific type of sugarlike molecule, or glycan, on the surface of cancer cells help them to spread into other tissues, according to researchers at the University of California, Davis. Published March 23 in Proceedings of the National Academy of Sciences, the work could lead to diagnostic tests and new therapies to slow or stop the spread of cancers.
