Scientists determine how two proteins help create organelles

Scientists at The Scripps Research Institute (TSRI) have determined how two proteins help create organelles, or specialized subunits within a cell, that play a vital role in maintaining cell health. This discovery opens the door for research on substances that could interfere with the formation of these organelles and lead to new therapies for cancer.

Membrane-proximal external region of HIV could be used to design vaccines

Beatriz Apellaniz, PhD holder of the UPV/EHU-University of the Basque Country, has studied in her PhD thesis HIV regions that could be used to design a vaccine. The researcher has focussed her research on a specific region of the surface protein of the Human Immunodeficiency Virus (HIV), which is responsible for the Autoimmune Deficiency Syndrome (AIDS), one of the diseases with the greatest human morbidity and mortality.

Fly model may help unravel genetic events that take place until development of a tumour

The wing of a fruit fly may hold the key to unraveling the genetic and molecular events that transform a normal cell into a cancerous one. The study, conducted on Drosophila melanogaster by scientists at the Institute for Research in Biomedicine (IRB Barcelona) and led by ICREA researcher Marco Mil-n, has reproduced each of the steps known to take place when a healthy cell turns cancerous.

Study shows how anaplasma phagocytophilum subverts natural processes

Bacteria that cause the tick-borne disease anaplasmosis in humans create their own food supply by hijacking a process in host cells that normally should help kill the pathogenic bugs, scientists have found.

New paper describes MCUR1 protein and its function

Most healthy cells rely on a complicated process to produce the fuel ATP. Knowing how ATP is produced by the cell's energy storehouse - the mitochondria -- is important for understanding a cell's normal state, as well as what happens when things go wrong, for example in cancer, cardiovascular disease, neurodegeneration, and many rare disorders of the mitochondria.

Tadalafil may offer therapeutic strategy in patients with Becker muscular dystrophy

Cedars-Sinai Heart Institute researchers have found in an initial clinical trial that a drug typically prescribed for erectile dysfunction or pulmonary hypertension restores blood flow to oxygen-starved muscles in patients with a type of muscular dystrophy that affects males, typically starting in childhood or adolescence.

Two-route drug combination best for horse joint pain

A combination of systemic nonsteroidal anti-inflammatory drugs plus intrasynovial glucocorticosteroids is superior to either medication alone in improving outcomes for lame horses with perisynovial pain of the metacarpophalangeal joint, report Dutch researchers.

Spoke sign may highlight pediatric middle ear effusion

The presence of a specific finding on otoscopy known as the spoke sign may help in the detection of middle ear effusion in pediatric patients, although its incorporation into clinical practice may require focused training, say US scientists.

Grove professor to investigate personalized therapies against breast cancer

For some time, researchers have known about disparities in diagnoses and outcomes among breast cancer patients based on race and age. However, they have been challenged to develop a set of criteria that can be used to reliably target drug delivery mechanisms based on an individual patient's tumor.

Paper illuminates importance of PKM2 in cancer development and progression

Researchers at The University of Texas MD Anderson Cancer Center have tracked down a cancer-promoting protein's pathway into the cell nucleus and discovered how, once there, it fires up a glucose metabolism pathway on which brain tumors thrive.

Study shows how MCUR1 protein helps regulate movement of calcium into mitochondria

A team of scientists from Temple University School of Medicine and the University of Pennsylvania has moved another step closer to solving a decades-long mystery of how the all-important flow of calcium into the cell's power source, the mitochondria, is controlled.

Major advance in understanding how flu viruses replicate within infected cells

Scientists at The Scripps Research Institute (TSRI) have made a major advance in understanding how flu viruses replicate within infected cells. The researchers used cutting-edge molecular biology and electron-microscopy techniques to "see" one of influenza's essential protein complexes in unprecedented detail. The images generated in the study show flu virus proteins in the act of self-replication, highlighting the virus's vulnerabilities that are sure to be of interest to drug developers.

UPC teams conduct research in biomedical engineering to improve people's health

Systems to improve patient rehabilitation, methods that help detect diseases, and smart biomaterials for optimising treatments—scientific advances in the field of biomedical engineering are unstoppable. A number of leading UPC teams are carrying out research aimed at harnessing technology to improve people's health.

Researchers characterize novel lysosomal PQ protein linked to cystinosis

Researchers at the Université Paris Descartes/CNRS and the Université libre de Bruxelles have made a major breakthrough in the study of cystinosis, a genetic disease that can lead to serious disorders, notably fatal kidney failure.

Researchers create 3D map of rod sensory cilium architecture affected by mutation

Using a new technique called cryo-electron tomography, two research teams at Baylor College of Medicine (www.bcm.edu) have created a three-dimensional map that gives a better understanding of how the architecture of the rod sensory cilium (part of one type of photoreceptor in the eye) is changed by genetic mutation and how that affects its ability to transport proteins as part of the light-sensing process.

Electrophysiology: an interview with Dr Kaylene Young

Bioelectricity is an essential part of our make-up. All cells in our body communicate by electrical activity. If an electrical charge is applied to one of our muscles it will interpret that electrical activity as a signal telling it to contract.

Synthetic membrane channels can be constructed through DNA nanotechnology

As reported in the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology."

Glycoprotein gene flags up heart disease

The glycosylphosphotidylinositol-anchored membrane glycoprotein CD14 gene significantly predicts cardiovascular mortality in adults aged 65 years or over, research shows.

New nanoparticle halts relapsing remitting multiple sclerosis in mouse model

In a breakthrough for nanotechnology and multiple sclerosis, a biodegradable nanoparticle turns out to be the perfect vehicle to stealthily deliver an antigen that tricks the immune system into stopping its attack on myelin and halt a model of relapsing remitting multiple sclerosis (MS) in mice, according to new Northwestern Medicine research.
