A different means of attack: Mayo Clinic

By Logan Lafferty

Could controlling blood vessel growth in the body be a key to treating rheumatoid arthritis, cancer and other diseases? The answer is perhaps, according to Mayo Clinic experts. Angiogenesis is the term used to describe blood vessel growth. Researchers are trying to understand and better control this complex process. Most recent research has focused on […]

How Senescent Cells Spur Aging and Cancer


In 1999 JAN M. VAN deursen and his colleagues at the Mayo Clinic in Rochester, Minn., wanted to see whether mangled chromosomes cause cancer. So they engineered mice deficient in a protein that helps to maintain chromosomal integrity. The rodents’ coils of DNA were duly deranged. Surprisingly, though, the animals were not particularly tumor-prone. Instead […]

Protein Switches from Protector to Aggressor in Tumors

By Kelley Luckstein

Researchers have reported that a protein thought to have a chemoprotective effect is actually a cancer promoter.    The study, led by Peter Storz, PhD from Mayo Clinic in Florida, builds on earlier findings from collaborating author Alex Toke, PhD, associate professor, Department of Pathology at Harvard Medical School. That work demonstrated that AKt, a […]

Can ‘nanobees’ sting tumors to death?

By Kelley Luckstein

US researchers have recently developed tiny artificial “nanobees”, which are armed with a cancer-killing toxin found in bee venom, that literally sting tumors to death. Tested on mice, after four to five injections of the Melittin-carrying nanobees over several days, the growth of breast cancer tumors in the mice was slowed by nearly 25 percent. […]
