By Richard Harth, Science Writer: The Biodesign Institute Under the electron microscope, a coronavirus may resemble a spiny sea urchin or appear crownlike, (the shape from which this family of pathogens takes its name). Previously recognized as the second leading cause of the common cold in humans and for economically important diseases in many domesticated animals, a new disease form abruptly emerged as a major public health concern in 2002, when the SARS coronavirus (CoV) surfaced in Asia....

Ancient viral sequences may protect against infection Over millions of years, retroviruses, which insert their genetic material into the host genome as part of their replication, have left behind bits of their genetic material in vertebrate genomes. In a recent study, published July 29 in the open-access journal PLoS Pathogens, a team of researchers have now found that human and other vertebrate genomes also contain many ancient sequences from Ebola/Marburgviruses and Bornaviruses "“...

Genetic architecture and the evolution of RNA viruses In biology and genetics, the concept of epistasis is what gives rise to the whole being more (or less) than the sum of its parts. The quantitative effect of a given mutation upon the traits of an organism has the potential to depend strongly upon the gene versions present in other parts of the genome, or even other mutations co-occurring in that gene. These genetic interactions, termed epistasis, can impact all aspects of organisms and...

RNA viruses hijack cellular enzyme to create viral replication factories on cell membranes Nihal Altan-Bonnet, assistant professor of cell biology, Rutgers University in Newark, and her research team have made a significant new discovery about RNA (Ribonucleic acid) viruses and how they replicate themselves. Certain RNA viruses "“ Poliovirus, Hepatitis C virus and Coxsackievirus "“ and possibly many other families of viruses copy themselves by seizing an enzyme from their host...

Study of vesicular stomatitis virus leads to model of viral assembly process Vesicular stomatitis virus, or VSV, has long been a model system for studying and understanding the life cycle of negative-strand RNA viruses, which include viruses that cause influenza, measles and rabies. More importantly, research has shown that VSV has the potential to be genetically modified to serve as an anti-cancer agent, exercising high selectivity in killing cancer cells while sparing healthy cells, and as...

The research, led by Professor Donny Strosberg of Scripps Florida, was published on March 4, 2009, in the Journal of General Virology's advance, online edition, Papers in Press.In the new study, Strosberg and his colleagues describe peptides (molecules of two or more amino acids) derived from the core protein of hepatitis C. The team found that these peptides inhibit not only dimerization of the core protein (the joining of two identical subunits), but also production of the actual virus...

RIVERSIDE, Calif. "“ Researchers at the University of California, Riverside have discovered that a simple worm, called C. elegans, makes an excellent experimental host for studying some of the most virulent viruses that infect humans. The researchers published their findings in the Aug. 18 issue of the journal Nature in a paper titled, Animal virus replication and RNAi-mediated antiviral silencing in C. elegans. UCR Professor of Plant Pathology Shou-Wei Ding co-authored the paper with...

Hepatitis C virus (HCV) is an enveloped, positive-sense single-stranded RNA virus of the family Flaviviridae. It consists of a core of genetic material surrounded by an icosahedra protective shell of protein. The genome consists of a single open reading frame that is 9600 nucleotide bases long. HCV replication takes several steps. It primarily replicates in the hepatocytes of the liver. It can also reproduce in peripheral blood mononuclear cells. There is a wide variety of genotypes and...
