Researchers identify gene mutation for that is essential for correct protein-processing in cells

A Jackson Laboratory research team led by Professor Patsy Nishina, Ph.D., has identified a mutation in a gene that's essential for correct protein-processing in cells. Defects in protein folding are associated with a variety of abnormalities and diseases.

Molecular interaction between structural HCV protein and protein critical to viral replication identified

Scientists from the Florida campus of The Scripps Research Institute have identified a molecular interaction between a structural hepatitis C virus protein (HCV) and a protein critical to viral replication. This new finding strongly suggests a novel method of inhibiting the production of the virus and a potential new therapeutic target for hepatitis C drug development.

New findings suggest way to treat lung diseases

A new study of an exotic, infectious virus that has caused three recent outbreaks in the United States reveals clues to how the virus might damage lungs during infection. The findings also suggest possible new ways to treat lung diseases in humans.

New gene therapy product reduces plasma cholesterol levels

Amsterdam Molecular Therapeutics (AMT) Holding N.V. a leader in the development of gene based therapies, today announced that its gene therapy product incorporating siRNA sequences into microRNA scaffolds to silence Apolipoprotein B100 (AAV-miApoB) was able to significantly lower plasma cholesterol levels in vivo over a period of 18 weeks. These preliminary results suggest that this approach could lead to a treatment for high cholesterol in humans

Scientists identify mechanism that regulate nuclear size

Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different species, but also in different types of cells in the same species and at different times during development. In addition, cancer cells are known to develop larger nuclei as they become more malignant. Screening for cervical cancer, for example, involves looking for grossly distorted nuclei in cervical cells collected during a Pap smear.

'Achilles heel' for HCV infection

Scientists at the Gladstone Institute of Virology and Immunology (GIVI) have found that an enzyme associated with the storage of fat in the liver is required for the infectious activity of the hepatitis C virus (HCV). This discovery may offer a new strategy for treating the infection.

Pathogens can delay entry into cells to ensure their survival, say researchers

Pathogens make themselves feel at home in the human body, invading cells and living off the plentiful amenities on offer. However, researchers at the Max Planck Institute for Infection Biology, Berlin, together with colleagues at Harvard University, reveal an opposite strategy used to ensure infection success. Pathogens can actually delay their entry into cells to ensure their survival.

Research provides better understanding of drugs used to treat, prevent cardiovascular disease

Using chemical labeling and mass spectrometry-based techniques, Mark Chance, PhD, director of the Case Western Reserve University School of Medicine Center for Proteomics and Bioinformatics and professor of physiology and biophysics; Sayan Gupta, PhD, instructor at the Case Center for Proteomics and Bioinformatics; and a research team from the University of Oxford, for the first time, were able to take a high resolution picture of the open state of a K+ channel, allowing them to comparatively analyze gating mechanisms important to heart function and nerve signaling - in addition these techniques have already permitted Case Western investigators to gain a deeper understanding of G-protein coupled receptors.

Successful growth of mouse embryonic stem cells in rat lungs raises hopes for engineering human transplants

For someone with a severe, incurable lung disorder such as cystic fibrosis or chronic obstructive pulmonary disease, a lung transplant may be the only chance for survival. Unfortunately, it's often not a very good chance. Matching donor lungs are rare, and many would-be recipients die waiting for the transplants that could save their lives.

Researchers discover gene mutations in autistic, mentally impaired patients

Researchers working with Professor Gudrun Rappold, Director of the Department of Molecular Human Genetics at Heidelberg University Hospital, have discovered previously unknown mutations in autistic and mentally impaired patients in what is known as the SHANK2 gene, a gene that is partially responsible for linking nerve cells.

AMT reports positive preclinical data from cholesterol targeting AAV gene therapy study

Amsterdam Molecular Therapeutics a world leader in gene therapy, today reported positive preclinical data from a study using an AAV gene therapy product to lower cholesterol.

Plaques in blood vessels may break by overproducing protein-digesting enzymes

University of Washington (UW) researchers have gathered evidence that dangerous plaques in blood vessels can rupture by overproducing protein-digesting enzymes. Plaques are fat-laden rough spots in the otherwise smooth walls of arteries. When a plaque ruptures, blood accumulates inside of it, a process known as plaque hemorrhage. The plaque enlarges and artery-blocking clots can form. If the flow of oxygen-rich blood is restricted, a heart attack, stroke, or damage to other organs can occur.

New findings shed light on how genetic damage to muscle cell proteins can lead to nemaline myopathy

New findings that shed light on how genetic damage to muscle cell proteins can lead to the development of the rare muscle-wasting disease, nemaline myopathy, are reported today (15 March) in the Biochemical Journal.

Cytokeratins 8 and 18 can strongly enhance breast cancer drug fulvestrant's anti-estrogenic activity

Women's responsiveness to the second-line breast cancer drug fulvestrant may depend on whether the cancer cells are expressing two key proteins, Indiana University Bloomington scientists report in this month's Cancer Biology & Therapy.

Study sheds light on how CL-HA stimulates collagen repair in skin

In the U.S. and around the world, the popularity of minimally invasive cosmetic procedures continues to increase. Soft tissue injectables, also known as dermal fillers, are popular procedures that improve the appearance of aging and sun-damaged skin by restoring lost volume and filling lines.

Chikungunya: Experimental vaccine successfully tested in monkeys

Imagine a mosquito-borne virus that has already infected millions of people in recent outbreaks in South and Southeast Asia, the islands of the Indian Ocean, Africa and northern Italy. Although seldom fatal, it causes highly painful arthritis-like symptoms that can linger for months or even years. It's capable of adapting to spread through a mosquito species common in much of North America. And no vaccine or treatment exists to protect humans from its effects.

New research findings may lead to new treatment options for abdominal aortic aneurysms

New research findings from a team at the Providence Heart + Lung Institute at St. Paul's Hospital and the University of British Columbia (UBC) may lead to new treatment options for abdominal aortic aneurysms (AAA) - a potentially fatal disease that currently has no pharmacological treatments.

New class of HCV inhibitors discovered by Eiger BioPharmaceuticals

Eiger BioPharmaceuticals, Inc., a biotechnology company developing antiviral therapies, announced today the publication of research from the labs of Stanford scientist and Eiger Founder, Dr. Jeffrey Glenn, M.D., Ph.D. and colleagues entitled, "Identification of a Novel Class of HCV Inhibitors". Published in the January 20th edition of Science and Translational Medicine, the research validates a domain, termed 4BAH2, within the non-structural protein (NS4B) of the HCV genome, as essential for HCV replication and describes the development of a high-throughput screen leading to the identification of small molecule inhibitors of 4BAH2.

Scientists discover new mechanism that explains role of EBV in tumor growth

The Epstein-Barr virus (EBV), a virus of the herpes family, has two distinct life phases: After infecting a cell it first goes into a resting phase. Under certain circumstances the virus can become active - and then induces tumor growth or promotes its synthesis in the cell.
