B1/Cdk1 protein which plays key role in cell division also boosts power of mitochondrial activity

An international team led by researchers at UC Davis has shown that the cyclin B1/Cdk1 protein complex, which plays a key role in cell division, also boosts the mitochondrial activity to power that process.

New technique of single-cell genomic analysis to reverse tissue engineering

Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body.

Acupuncture protects brain neurons against injury in rats following heroin relapse

Heroin abuse can damage many brain areas, including the pedunculopontine tegmental nucleus of the midbrain, the ventral tegmental area, and nucleus accumbens. Persistent use of heroin induced irreversible damage to the nervous system.

Researchers reveal how cells respond to mechanical manipulation

The push and pull of physical force can cause profound changes in the behavior of a cell. Two studies from researchers working at the UNC Lineberger Comprehensive Cancer Center reveal how cells respond to mechanical manipulation

NRAS gene that plays fundamental role in cancer development produces five gene variants, says study

A new study shows that a gene discovered 30 years ago and now known to play a fundamental role in cancer development produces five different gene variants (called isoforms), rather than just the one original form, as thought.

Genome Project offers new leads to improve outcomes for children with high-grade glioma brain tumors

The St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project has identified new mutations in pediatric brain tumors known as high-grade gliomas (HGGs), which most often occur in the youngest patients.

Researchers generate 3D model of human malaria parasite genome

A research team led by a cell biologist at the University of California, Riverside has generated a 3D model of the human malaria parasite genome at three different stages in the parasite's life cycle - the first time such 3D architecture has been generated during the progression of the life cycle of a parasite.

Electrode placement affects subthalamic nucleus stimulation outcomes

Researchers have identified factors associated with motor, cognitive and mood outcomes after deep-brain stimulation (DBS) of the subthalamic nucleus in a large cohort of patients with Parkinson’s disease.

Too little or too much of SRPK1 enzyme promotes cancer, shows research

Researchers at the University of California, San Diego School of Medicine have found that too little or too much of an enzyme called SRPK1 promotes cancer by disrupting a regulatory event critical for many fundamental cellular processes, including proliferation.

Study looks at ability of nontoxic molecules to store harmful alpha emitting radioisotopes

Researchers have discovered that microscopic "bubbles" developed at Kansas State University are safe and effective storage lockers for harmful isotopes that emit ionizing radiation for treating tumors.

Stowers team reports genome-wide analysis of genes that drive cell division in multicellular organism

In textbooks, the grand-finale of cell division is the tug-of-war fought inside dividing cells as duplicated pairs of chromosomes get dragged in opposite directions into daughter cells.

Study: Obesity causes changes in colon that may lead to colorectal cancer

Obesity, rather than diet, causes changes in the colon that may lead to colorectal cancer, according to a study in mice by the National Institutes of Health. The finding bolsters the recommendation that calorie control and frequent exercise are not only key to a healthy lifestyle, but a strategy to lower the risk for colon cancer, the second leading cause of cancer-related death in the United States.

NeuroSigma gets approval to market Monarch eTNS System in Australia

NeuroSigma, Inc., a California-based life-sciences company focused on commercialization of its non-invasive Monarch eTNS System for the treatment of neurological and neuropsychiatric disorders, today announced that it has received approval from the Therapeutic Goods Administration to market its Monarch eTNS System in Australia.

Cumulative amount of specific gene products affects changes in cell fate, say researchers

Johns Hopkins biologists have discovered that when biological signals hit cells in rhythmic waves, the magnitude of the cells' response can depend on the number of signaling cycles — not their strength or duration. Because such so-called “oscillating signaling cycles” are common in many biological systems, the scientists expect their findings in single-celled organisms to help explain the molecular workings of phenomena such as tissue and organ formation and fundamental forms of learning.

Misplaced protein provides promising drug target for kidney cancer

The shortage of oxygen, or hypoxia, created when rapidly multiplying kidney cancer cells outgrow their local blood supply can accelerate tumor growth by causing a nuclear protein called SPOP-which normally suppresses tumor growth-to move out of the nucleus to the cytoplasm, where it has the opposite effect, promoting rapid proliferation.

Researchers identify steps by which cell removes RNA from cytoplasm

RNA encodes the proteins that play a key role in cellular reproduction, but the manner in which cells regulate its removal once these proteins are synthesized remains a mystery. One piece of this mystery has been solved as researchers at the University of North Carolina at Chapel Hill who have identified the steps by which a cell removes RNA from the cytoplasm.
