A major study conducted at the Sahlgrenska Academy has now disproved theories of a viral cause for breast cancer and the brain tumor, glioblastoma. The study, which was based on over seven billion DNA sequences and which is published in Nature Communications, found no genetic traces of viruses in these forms of cancer. It has been scientifically proven that about 15 per cent of all cancer cases are the result of viral infection, but many researchers believe that even more cancers could be...

UCSF researchers find virus from the ocean that confounds lab analysis The report by scientists of a new hepatitis virus earlier this year was a false alarm, according to UC San Francisco researchers who correctly identified the virus as a contaminant present in a type of glassware used in many research labs. Their finding, they said, highlights both the promise and peril of today’s powerful “next-generation” lab techniques that are used to track down new agents of disease. In...

Parents do everything they can to protect their children against all of the nasty germs floating around classrooms across the country this time of year. Doctors and researchers at Nationwide Children’s Hospital, however, are looking into how those same types of common viruses can actually help treat a child who is diagnosed with certain cancers. Columbus, Ohio (PRWEB) September 12, 2013 Parents do everything they can to protect their children against all of the nasty germs floating...

System represents major advance in studying virus By differentiating monkey stem cells into liver cells and inducing successful infection, researchers from the Icahn School of Medicine at Mount Sinai have shown for the first time that the hepatitis C virus (HCV) can replicate in monkeys, according to research published in the journal Gastroenterology. The new findings may lead to the first new animal model and provide new avenues for developing treatments and vaccines for this disease,...

Viruses have historically been classified into one of two types — those with an outer lipid-containing envelope and those without an envelope. For the first time, researchers at the University of North Carolina have discovered that hepatitis A virus, a common cause of enterically-transmitted hepatitis, takes on characteristics of both virus types depending on whether it is in a host or in the environment. "The whole universe of virology is divided into two types of viruses —...

Clue To Hepatitis B Virus Genetic Code Provided By 16th-century Korean Mummy
2012-05-29 09:36:02

The discovery of a mummified Korean child with relatively preserved organs enabled an Israeli-South Korean scientific team to conduct a genetic analysis on a liver biopsy which revealed a unique hepatitis B virus (HBV) genotype C2 sequence common in Southeast Asia. Additional analysis of the ancient HBV genomes may be used as a model to study the evolution of chronic hepatitis B and help understand the spread of the virus, possibly from Africa to East-Asia. It also may shed further light...

Polyomavirus is the sole genus of viruses within the family Polyomaviridae. Ludwik Gross discovered the first polyomavirus, Murine polyomavirus, in 1963. Many polyomaviruses infect birds and mammals and have been extensively studied as tumor viruses in humans and animals. Polyomaviruses are DNA-based, small, and icosahedral in shape. They can potentially cause tumors and often persist as latent infections in a host without causing disease. There are three major clades or...

Papillomaviridae is a taxonomic family of non-enveloped DNA viruses, collectively known as papillomaviruses. There are several hundred species, or types, of papillomaviruses that have been identified. Most infections are asymptomatic or cause small benign tumors. Types 16 and 18 carry risks of becoming cancerous. They replicate in the basal layer of the body surface tissues. Typically they infect the skin but can infect a particular body surface. HPV type 1 tends to infect the soles of...

Merkel cell polyomavirus (MCV or MCPyV), first discovered in January 2008, is one of seven human tumor viruses. It is suspected to cause most of Merkel cell carcinoma which is a rare, aggressive form of skin cancer. Around 80% of Merkel cell carcinoma tumors are found to be infected with MCV. It is found in respiratory secretions suggesting that it may be transmitted by a respiratory route. Usually the tumors with MCV viruses go through at least two mutations that render the virus...

The Epstein-Barr virus (EBV), or human herpesvirus 4, is part of the herpes family and causes cancer. It is one of the most common viruses in humans and is correlated to the pathogenesis of multiple autoimmune diseases including rheumatoid arthritis, systemic lupus, dermatomyositis, and multiple sclerosis. It can also cause several lymphoproliferative disorders and cancers. Most people gain adaptive immunity after being infected by EBV. In the US half of all five-year-olds and 90-95% of...
