Many cancers result from chromosomal translocations in tumor cells. Hundreds of cancer-causing translocations have been discovered, but current methods for detecting them have significant shortcomings.
The technique, developed in the lab of Stephen Lessnick, M.D., Ph.D., director of the Center for Children's Cancer Research at HCI, combines microarray technology, which can look for thousands of translocations in a single test, with a novel antibody that is used to detect the presence of the translocation.
"We're moving past the age when a pathologist looking through the microscope at a tumor sample is the best way to diagnose what type of cancer it is," said Lessnick. "The molecular tests currently available are slow, inefficient, and expensive, and one of the biggest issues is that you need high-quality tumor samples, not always available in the clinical setting, to do them." According to Lessnick, his method tolerates real-life specimens much better than the current standard techniques.
"Originally, this method was used in HCI's Cairns lab (headed by Bradley R. Cairns, Ph.D.) to study RNA in yeast. We took their method and applied it to our study of chromosomal translocations in human tissue," Lessnick said. He said the next task is to find a commercial partner to develop this research from a 'proof of principle' into a diagnostic test that doctors can use to help their patients.
"With this method, there's potential to develop a single array that could test for every known cancer-causing translocation simultaneously. Currently, a clinician has to decide beforehand which specific cancer to test," he said.The research used Ewing's sarcoma (a rare childhood cancer) as the case study for developing the method, but Lessnick maintains that the technology can be easily applied to any type of cancer caused by a translocation.
Lessnick is a Jon and Karen Huntsman Presidential Professor in Cancer Research, and a professor in the Division of Pediatric Hematology/Oncology at the University of Utah. Other HCI investigators participating in the research include Bradley R. Cairns, Ph.D., HCI Senior Director of Basic Science, Howard Hughes Medical Institute Investigator, and professor in the Department of Oncological Sciences at the University of Utah, as well as Brett Milash, Ph.D., and Brian Dalley, Ph.D., of the Microarray and Genomic Analysis Core Facility.This work was supported by the NIH via R21 CA138295 to SLL, T32 GM007464 to ND, and P30 CA042014 to Huntsman Cancer Institute. Cairns is supported by the Howard Hughes Medical Institute. Additional work in the Lessnick lab is supported by Sidney's Incredible Defeat of Ewing's Sarcoma (SIDES).

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
