The original tumor is itself not typically fatal for many types of cancer. Instead, it is the process of metastasis distributing a small subpopulation of cells from the primary tumor to other parts of the body, which all too often kills patients. Now researchers at the Albert Einstein have identified two molecules of College of Medicine of Yeshiva University, with the cancer within the body can spread. These findings could eventually prevent the molecules to therapies, the metastasis of inactive.

The regulatory molecules are involved in the formation of Invadopodia, the tabs, the tumor cells, metastatic by always rod-shaped, degrading extracellular material, penetrate blood vessels and, finally, seeding to activate in other parts of the body.

The research appears online by current biology 7 issue in April. The study senior author is John Condeelis, PhD., co-chair and Professor of Anatomy and structural biology, co-director the gruss Lipper Biophotonics Center and owner of Judith and Burton s. Resnick of Chairman translational research on Einstein.

Dr. Condeelis and his team identified two molecules (p190RhoGEF and p190RhoGAP), the rules the activity of RhoC, an enzyme that plays a crucial role during the tumour metastases and biomarkers for invasive breast cancer was found.

"As also in vivo studies have shown in vitro, that RhoC that activity is positively correlated increased invasion and motility of tumor cells, with" Center and the school of Anatomy and structural biology said corresponding author José Javier Bravo-Cordero, PhD, research fellow in the laboratory of Dr. Condeelis and Assistant Professor Louis HodgsonPh.d., in the gruss Lipper biophotonics. "The new players we could have identified as regulation RhoC in tests, tumor therapeutic drug targets as metastases."

The other researchers in the Einstein study, all in the Department of Anatomy and structural biology, Oser, research technician Xiaoming Chen, Robert Eddy, PhD., and Dr. Hodgson were student Matthew m.d. / Ph.d.. This study is the first deal with a new generation of G-protein biosensors, developed the Dr. Hodgson. Is the title of the paper "a new time RhoC activation pathway locally regulates Cofilin activity in Invadopodia."

The research was funded by the national institutes of health.
