A University of British Columbia doctoral candidate has discovered a previously unknown mechanism for silencing retroviruses, segments of genetic material that can lead to fatal mutations in a cell's DNA. The findings, published April 7 in the journal Nature, could lead to new cancer treatments that kill only tumor cells and leave healthy surrounding tissue unharmed. Danny Leung, a 27-year-old graduate student in the laboratory of Asst. Prof. Matthew Lorincz in the Dept. of Medical Genetics,...

Four drugs used to treat HIV infection can inhibit a retrovirus recently linked to prostate cancer and chronic fatigue syndrome, researchers at Emory University/Atlanta Veterans Affairs Medical Center and the University of Utah have shown. The results were published on April 1, 2010 by the journal PLoS One. The findings suggest that if XMRV (xenotropic murine leukemia virus-related virus) is proven to be a cause for prostate cancer or chronic fatigue syndrome, those illnesses may be treatable...

Johns Hopkins scientists have found that a safe and inexpensive antibiotic in use since the 1970s for treating acne effectively targets infected immune cells in which HIV, the virus that causes AIDS, lies dormant and prevents them from reactivating and replicating. The drug, minocycline, likely will improve on the current treatment regimens of HIV-infected patients if used in combination with a standard drug cocktail known as HAART (Highly Active Antiretroviral Therapy), according to research...

New study from Universite de Montreal and VGTI may lead to improved defenses New findings from a Universit© de Montr©al and the Vaccine and Gene Therapy Institute of Florida (VGTI) study, in collaboration with scientists from the NIH and the McGill University Health Center, may soon lead to an expansion of the drug arsenal used to fight HIV. The Canada-U.S. study published today in the journal Nature Medicine characterizes the pivotal role of two molecules, PD-1 and IL-10, in...

A study shows that viruses may have changed the course of human evolution, and the Italian scientists involved in the research say they believe that the discovery might help in the creation of better drugs and vaccines to fight them. Researchers from Scientific Institute IRCCS, Milan University and the Politecnico di Milano found more than 400 different mutations in 139 genes that are significant factors in the risk of catching viruses. The findings might help explain why some people hardly...

Novel therapies could improve potency of existing AIDS treatments, help to combat drug-resistant virus strains A team of scientists at The Scripps Research Institute has identified two compounds that act on novel binding sites for an enzyme used by the human immunodeficiency virus (HIV), the virus that causes AIDS. The discovery lays the foundation for the development of a new class of anti-HIV drugs to enhance existing therapies, treat drug-resistant strains of the disease, and slow the...

Researchers have made a breakthrough in HIV research that had eluded scientists for over 20 years, potentially leading to better treatments for HIV, in a study published today in the journal Nature. The researchers, from Imperial College London and Harvard University, have grown a crystal that reveals the structure of an enzyme called integrase, which is found in retroviruses like HIV. When HIV infects someone, it uses integrase to paste a copy of its genetic information into their DNA. Prior...

Human genomes carry traces of a 40-million-year-old animal virus that supposedly infected their ancestors, reported AFP. Research published on Wednesday by the British science journal Nature said the invader is called bornavirus, a pathogen first identified in 1970s that infects the brain. Keizo Tomonaga of Japan's Osaka University headed up a team of scientists as they compared the DNA of a range of mammals, including humans, apes, elephants, marsupials and rodents, to look for markers of...

Professor Denis Archambault of the Department of Biological Sciences of Universit© du Qu©bec à Montr©al (UQAM), and doctoral student Andrea Corredor Gomez have made a major discovery in the field of molecular biology. They have unlocked some of the secrets of a viral protein, known as Rev, which is very different from other proteins of the same type studied to date. The results of their research were recently published in the prestigious Journal of Virology....

How HIV is assembled and released from infected cells Although recent advances have raised hopes that a protective vaccine can be developed, acquired immunodeficiency syndrome (AIDS) remains a major public health problem. Much has been learned about HIV-1, the virus that causes the disease. However, basic aspects of person-to-person transmission and of the progressive intercellular infection that depletes the immune system of its vital T cells remain imperfectly understood. In a paper...

Word of the Day
  • Remarkable; prodigious.
  • Audacious; gutsy.
  • Completely; extremely.
