New Weapons In The Fight Against Canine Cancer
2012-09-11 10:31:42

April Flowers for redOrbit.com - Your Universe Online Two recent studies have shown real progress in killing cancer cells in dogs. The first study, from the University of Illinois at Urbana-Champaign, reports that myxoma, a pox virus that affects rabbits but not humans, dogs or other vertebrates studied so far, infects several different types of canine cancer cells in cell culture while sparing healthy cells. The study adds to the evidence that viruses or modified viruses will emerge as...

Lee Rannals for redOrbit.com — Your Universe Online Boosting the activity of a particular enzyme can help block tumors from growing, according to research published in Nature Chemical Biology. Cancer cells use up most of their energy by reproducing themselves, but in order to do this they must produce new cellular building blocks like DNA, carbohydrates and lipids. Biologists found that jacking up the activity of the enzyme pyruvate kinase can disrupt the production of tumors...

One Of Cancer's Tricks Determined By Chemists

Caltech chemists determine 1 way tumors meet their growing needs Behaving something like ravenous monsters, tumors need plentiful supplies of cellular building blocks such as amino acids and nucleotides in order to keep growing at a rapid pace and survive under harsh conditions. How such tumors meet these burgeoning demands has not been fully understood. Now chemists at the California Institute of Technology (Caltech) have shown for the first time that a specific sugar, known as GlcNAc...

A compound found in green tea could be a weapon in treatments for tackling cancer, according to newly-published research at the University of Strathclyde in Glasgow, Scotland. The extract, known as epigallocatechin gallate, has been known to have preventative anti-cancer properties but fails to reach tumors when delivered by conventional intravenous administration. However, in initial laboratory tests at the Universities of Strathclyde and Glasgow, researchers used an approach which...

An inexpensive antifungal drug, thiabendazole, slows tumor growth and shows promise as a chemotherapy for cancer. Scientists in the College of Natural Sciences at The University of Texas at Austin made this discovery by exploiting the evolutionary relatedness of yeast, frogs, mice and humans. Thiabendazole is an FDA-approved, generic drug taken orally that has been in clinical use for 40 years as an antifungal. It is not currently used for cancer therapy. Hye Ji Cha, Edward Marcotte,...

Particles that shut off cancer genes could also allow researchers to screen potential drug targets more rapidly By sequencing cancer-cell genomes, scientists have discovered vast numbers of genes that are mutated, deleted or copied in cancer cells. This treasure trove is a boon for researchers seeking new drug targets, but it is nearly impossible to test them all in a timely fashion. To help speed up the process, MIT researchers have developed RNA-delivering nanoparticles that allow for...

Cancer Stem Cell Discovery Could Hold Key To First Real Cure For The Disease

Lawrence LeBlond for redOrbit.com - Your Universe Online In some cancers, doctors find that tumors shrink with treatment, yet only briefly, and then come back with a vengeance. Now, recent studies on three different types of tumors suggest that cancer stem cells are resistant to chemotherapy and radiotherapy and may explain why cancer becomes resistant to treatment. A team of independent researchers came to the realization while studying tumors of the brain, intestines and skin in mice....

(Ivanhoe Newswire) — A new therapeutic target for advanced breast cancer has shown promising results in mouse models, according to a study performed by Western University. Lynne-Marie Postovit of Western´s Schulich School of Medicine and Dentistry analyzed a protein called Nodal, which is primarily found in embryonic or stem cells. She discovered high levels of Nodal in aggressive breast cancer tumors. The protein was found to promote vascularization in the tumor, providing...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
