Scientists identify overlooked consequence of spatial separation of cells into nucleus, cytoplasm

Genetically identical cells do not always behave the same way. According to the accepted theory, the reason are random molecular processes - known as random noise. For decades this view has been underpinned by numerous experiments and theoretical models.

UMMS researchers identify new life cycle stage in HIV infection

Researchers at the University of Massachusetts Medical School have identified a new life cycle stage in HIV infection, thanks to a novel technique they developed to take images of intact infected cells.

Light-driven protein has potential to become key tool for optogenetics

Biophysicists have developed a hypothesis to explain the function of a light-driven protein which pumps sodium ions across a cell membrane, and they have revealed the key structural feature of these pumps. The scientists see these sodium pumps as being highly promising tools in using light signals to control nerve cells – which is exactly what is involved in the new scientific field of optogenetics.

Research shows how scientists altered stem cells, triggered bone growth

Imagine you have a bone fracture or a hip replacement, and you need bone to form, but you heal slowly - a common fact of life for older people. Instead of forming bone, you could form fat. Researchers at the University of North Carolina School of Medicine may have found a way to tip the scale in favor of bone formation. They used cytochalasin D, a naturally occurring substance found in mold, as a proxy to alter gene expression in the nuclei of mesenchymal stem cells to force them to become osteoblasts (bone cells).

Scientists identify new jelly-like properties of essential proteins that lead to serious diseases

Scientists at the University of Cambridge have identified a new property of essential proteins which, when it malfunctions, can cause the build up, or 'aggregation', of misshaped proteins and lead to serious diseases.

New research shows that autophagy can operate in cell nucleus to guard against start of cancer

Autophagy, literally self-eating or the degradation of unwanted cellular bits and pieces by the cell itself, has been shown for the first time to also work in the cell nucleus. In addition, in this setting it plays a role in guarding against the start of cancer, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

Researchers identify role of cGAS enzyme in autoimmune diseases

Activating an enzyme that sounds an alarm for the body's innate immune system causes two lethal autoimmune diseases in mice, while inhibiting the same enzyme rescues them, UT Southwestern Medical Center researchers report.

Genetic mutation linked to ALS, FTD prevents proteins from entering and exiting the cell's nucleus

Three teams of scientists supported by the National Institutes of Health showed that a genetic mutation linked to some forms of amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD) may destroy neurons by disrupting the movement of materials in and out of the cell's nucleus, or command center where most of its DNA is stored.

Researchers identify molecular switch that can avoid inflammation

Our immune system is vital to us and can sometimes overreact causing chronic illnesses, such as for instance rheumatism and allergy. Now, researchers from Umeå University and University of Gothenburg have identified a molecular switch - MYSM1 - that can suppress such an overreaction and avoid inflammation.

Valerion announces positive results from non-clinical pilot study of VAL-1221 for treatment of Pompe disease

Valerion Therapeutics, LLC yesterday announced positive results from a non-clinical "proof of concept" pilot study for a novel humanized antibody and acid alpha glucosidase (GAA) fusion candidate for the treatment of Pompe disease.

Two studies highlight important new discovery around most common genetic defect linked to ALS

In today's issue of Nature, two new studies funded in part by The ALS Association both highlight an important new discovery around the C9orf72 mutation, the most common genetic defect associated with amyotrophic lateral sclerosis (ALS).

Common gene mutation may cause brain damage associated with ALS and FTD

Johns Hopkins researchers say they have discovered some of the first steps in how a very common gene mutation causes the brain damage associated with both amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

Scientists reveal how a common gene mutation in ALS and FTD disrupts normal cell function

Researchers have determined how the most common gene mutation in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) disrupts normal cell function, providing insight likely to advance efforts to develop targeted therapies for these brain diseases.

Determining the dynein-dynactin complex structure: an interview with Dr Gabriel C. Lander

This is a macromolecular assembly is made up of two components, dynein and dynactin, that works to move molecular cargo (organelles, RNA, vesicles, proteins, viruses) along microtubule highways within our cells.

Sigma 1 receptor appears to play vital role in supporting the retina

A receptor that is already a target for treating neurodegenerative disease also appears to play a key role in supporting the retina, scientists report.

Scientists develop biosensor to measure abnormal activity of cell 'fuel' carrier

To be able to function, cell mitochondria import "fuel" using a carrier, the Mitochondrial Pyruvate Carrier (MPC). In order to determine whether the MPC is still functional in malignant cells, the team of Professor Jean-Claude Martinou, at the University of Geneva, Switzerland, has just developed a biosensor to measure its live activity.

Researchers uncover new mechanism that p53 protein uses to trigger cell death

Researchers have identified a new mechanism that the tumor suppressor protein p53 uses to trigger cell death via apoptosis and have shown how the process could be harnessed to kill cancer cells. St. Jude Children's Research Hospital scientists led the study, which appears today in the scientific journal Molecular Cell.

Research breakthrough opens door to a world of regenerative medicine for treating mitochondrial disease

A study led by Shoukhrat Mitalipov, Ph.D., and Hong Ma, M.D., Ph.D., at the Center for Embryonic Cell and Gene Therapy at Oregon Health & Science University and the Oregon National Primate Research Center has revealed the first critical step in developing novel gene and stem cell therapy treatments for patients with mitochondrial disease.
