Protein that allows Ebola virus to attack cells discovered

A U.S. research team has discovered a protein called Niemann-Pick C1 (NPC1), which they found was responsible for allowing Ebola virus to enter and replicate within cells.

Researchers discover NPC1 protein as crucial for Ebola virus to enter host cells

Although outbreaks are rare, Ebola virus, the cause of Ebola hemorrhagic fever (EHF), is one of the deadliest known viruses affecting humans. According to the World Health Organization (WHO), approximately 1,850 EHF cases with more than 1,200 deaths have been documented since the virus was identified in 1976.

Study reveals structure of ribosomal assembly intermediate

As part of a joint research effort with the University of Michigan, scientists from the Florida campus of The Scripps Research Institute have for the first time defined the structure of one of the cell's most basic engines, which is required for cell growth, as it assembles from its components.

New protein discovery could help develop intracellular biologic drugs

Permeon Biologics, a biopharmaceutical company pioneering a novel class of intracellular protein biologics, today announced the discovery of an entirely new class of naturally occurring human supercharged proteins called Intraphilins-.

Introducing maspin protein into tumor nucleus can stop growth and spread of cancer

According to the Canadian Cancer Society, one in four Canadians will die of cancer. This year alone, the disease will kill an estimated 75,000 people. With incidence rates on the rise, more cancer patients are facing grave prognoses.

Scientists convert brain cells into cardiomyocytes

For the past decade, researchers have tried to reprogram the identity of all kinds of cell types. Heart cells are one of the most sought-after cells in regenerative medicine because researchers anticipate that they may help to repair injured hearts by replacing lost tissue.

New strategy may combat age-associated infertility and birth defects

A strategy that has been shown to reduce age-related health problems in several animal studies may also combat a major cause of age-associated infertility and birth defects.

Scientists discover linchpin protein that drives mitochondria's calcium machinery

Mitochondria, those battery-pack organelles that fuel the energy of almost every living cell, have an insatiable appetite for calcium. Whether in a dish or a living organism, the mitochondria of most organisms eagerly absorb this chemical compound.

MDC researchers comprehensively quantify gene expression for the first time

How do genes control us? This fundamental question of life still remains elusive despite decades of research. Genes are blueprints for proteins, but it is the proteins that actually carry out vital functions in the body for maintaining life. Diseases such as cancer are not only characterized by altered genes, but also by disturbed protein production.

Salmonella enterica bacterium activates virulence genes through Fur protein

Salmonella enterica, one of the main causes of gastrointestinal infections, modulates its virulence gene expression, adapting it to each stage of the infection process, depending on the free iron concentration found in the intestinal epithelium of its host.

Long non-coding RNA promotes melanoma cell survival and invasion

Traditionally, RNA was mostly known as the messenger molecule that carries protein-making instructions from a cell's nucleus to the cytoplasm. But scientists now estimate that approximately 97 percent of human RNA doesn't actually code for proteins at all. A flurry of research in the past decade has revealed that some types of non-coding RNAs switch genes on and off and influence protein function.

New nano-vault delivery system can fight cancer

UCLA scientists have discovered a way to wake up the immune system to fight cancer by delivering an immune system-stimulating protein in a nanoscale container called a vault directly into lung cancer tumors, harnessing the body's natural defenses to fight disease growth.

Major breakthrough in understanding of amyotrophic lateral sclerosis

Brandeis researchers have made a significant advance in the effort to understand amyotrophic lateral sclerosis by successfully reversing the toxicity of the mutated protein in the familial type of the disease.

Researchers package drug-loaded 'nanodisks' into vault nanoparticles for therapeutic drug delivery

There's no question, drugs work in treating disease. But can they work better, and safer?

Scientists discover new mechanism behind Salmonella invasion into gut cells

Scientists from the Helmholtz Centre for Infection Research in Braunschweig, Germany have discovered a new, hitherto unknown mechanism of Salmonella invasion into gut cells: In this entry mode, the bacteria exploit the muscle power of cells to be pulled into the host cell cytoplasm.

Blocking abnormal movement of mutated human FUS gene also blocks ALS process

In the first animal model of Amyotrophic Lateral Sclerosis (ALS), developed by Dr. Udai Pandey, Assistant Professor of Genetics at LSU Health Sciences Center New Orleans, Dr. Pandey's lab has found in fruit flies that blocking the abnormal movement of a protein made by a mutated gene called FUS also blocks the disease process.

Key enzyme in non-small cell lung cancers could make standard chemotherapy more effective

Scientists at the Barbara Ann Karmanos Cancer Institute in Detroit today presented a study at the American Association for Cancer Research's 102nd Annual Meeting 2011 that identifies a key enzyme in non-small cell lung cancers that could potentially make standard chemotherapy more effective against this highly deadly disease.

Scientists effectively combine two methods used as vehicles to carry DNA into cell nuclei

Scientists at Polytechnic Institute of New York University (NYU-Poly) and at the NYU College of Dentistry have discovered a biochemical version of a principle well known among confectioners. Call it the "peanut butter and chocolate" rule: Sometimes two things work better together than alone.
