Gene that destroys cancerous cells also causes ageing

The role of one of our genes which protects us from cancer but could also cause us to age will be explained in a lecture at the University of Leicester.

KI's chemical interaction map shows how inhibitors bind to PARP enzymes

A team of researchers at Karolinska Institutet in Sweden has generated a map over the effects of small drug-like molecules on PARP1 and other similar proteins in the body. This map may explain the mechanism behind putative side effects of the so-called PARP inhibitors, and can play an important role in the development of novel tailor-made cancer drugs.

Modified imatinib cancer drug prevents morphine tolerance in rats

By reformulating the common cancer drug imatinib (Gleevec), researchers have eliminated morphine tolerance in rats - an important step toward improving the effectiveness of chronic pain management in patients, according to researchers at The University of Texas MD Anderson Cancer Center.

Evolutionary biologist receives LRI grant for lupus research

Evolutionary biologist Harmit Singh Malik, Ph.D., of Fred Hutchinson Cancer Research Center, has received a $300,000 grant from the Lupus Research Institute to study the potential role of "genetic conflicts" in the development of lupus, an autoimmune disease.

Study: 3D organization of chromosomes plays a role in cancer genomics

It is well understood that chromosomal translocation - a process whereby pieces of two chromosomes break off and exchange places - is a hallmark of many cancers including leukemia, thyroid cancer and lymphoma and play an important part in how healthy cells become cancerous. The role spatial proximity plays in why certain chromosomal translocations happen repeatedly, however, has been a long-standing area of debate among scientists.

Biochemists determine first crystal structure of an immunoproteasome

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells that due to a viral infection present non-self peptides at their surface. In autoimmune diseases this mechanism is deregulated and the immune system also eliminates uninfected cells by mistake.

Thrombocytosis linked to severity of ovarian cancer

Highly elevated platelet levels fuel tumor growth and reduce the survival of ovarian cancer patients, an international team of researchers led by scientists at The University of Texas MD Anderson Cancer center reports in the New England Journal of Medicine.

Online anatomy dissector a 'superb learning tool': JAMA

A Georgetown University School of Medicine professor's online anatomy dissector designed to assist medical students in learning gross anatomy is described as a "superb learning tool" in a review published in the February 15 issue of the Journal of the American Medical Association (JAMA).

Chemists create new molecule that can tangle inside the DNA for up to 16 days

Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported.

mRNA sequencing reveals transcriptomic landscape of breast cancer

GW Cancer Research Team in the Department of Biochemistry and Molecular Biology, in the School of Medicine and Health Sciences, published a study that is the first of its kind to use mRNA sequencing to look at the expression of genome, at a unprecedented resolution at the current time, in three types of breast cancer.

Study shows how malaria parasite changes into banana form before sexual reproduction

New research from the University of Melbourne shows how the malaria parasite (Plasmodium falciparum) changes into a banana shape before sexual reproduction, a finding that could provide targets for vaccine or drug development and may explain how the parasite evades the human immune system.

Scientists create new mouse model for medulloblastoma

Scientists at Sanford-Burnham Medical Research Institute (Sanford-Burnham) developed a new mouse model for studying a devastating childhood brain cancer called medulloblastoma.

Researchers discover a connection of peroxisomal protein import and receptor export

The group of Prof. Dr. Ralf Erdmann at the Ruhr-Universit-t Bochum discovered a connection of peroxisomal protein import and receptor export. In the Journal of Biological Chemistry, they disclosed that enzymes only get imported into certain cell organelles (peroxisomes) upon coupling of their import to the recycling of their transport protein.

Discovery sheds light on what happens in cells when DNA is damaged

A research group in the Faculty of Medicine & Dentistry at the University of Alberta is hoping its latest discovery could one day be used to develop new therapies that target certain types of cancers.

Study investigates how cytokine IFN-λ release is regulated

In new research appearing in this month's issue of the journal Nature Immunology, Roy Curtiss, director of the Center for Infectious Diseases and Vaccinology at the Biodesign Institute at Arizona State University, along with international collaborators, investigates the coordination of a particular type of immune response, involving the release of of IFN-λ- a cell-signaling protein molecule known as a cytokine.

Injecting MWCNTs can kill tumor initiating breast cancer stem cells

Wake Forest Baptist Medical Center researchers have again proven that injecting multiwalled carbon nanotubes (MWCNTs) into tumors and heating them with a quick, 30-second laser treatment can kill them.

Sanford-Burnham, Florida Hospital and Moffitt partner to develop PMP Florida

Moffitt Cancer Center, Sanford-Burnham Medical Research Institute and Florida Hospital have announced they will collaborate on the creation of a Personalized Medicine Partnership of Florida (PMP Florida). The partnership will conduct collaborative research to accelerate discovery and develop new treatments in the areas of cancer and metabolic diseases, including obesity, diabetes and cardiovascular disease.
