New genes involved in acute lymphoblastic leukemia play fundamental role in prognosis of the disease
Date:2/6/2009

This release is available in Spanish.

The inactivity or "silence" of certain genes plays a fundamental role in the prognosis of acute lymphoblastic leukemia as well as in response to treatment, according to the results of research involving a team made up of specialists from the University Hospital of Navarra and the Center for Applied Medical Research at the same University of Navarra, as well as the Reina Sofa Hospital in Cordoba, Andalusia.

In concrete, the work confirmed that the inactivation of 13 microRNAs (a type of gene) by an epigenetic mechanism (capable of modulating the functions of the genetic code), is associated with higher mortality amongst patients with ALL. In total, the study involved 353 patients - 179 children and 174 adults - with acute lymphoblastic leukaemia). The results open up new therapeutic options on demonstrating the possibility of using these microRNAs as new targets in the treatment of this cancer illness. The conclusions of the research were recently published in the scientific journal with the greatest international impact in its speciality, the Journal of Clinical Oncology.

Involved in the research work was a team made up of specialists from the University Hospital of Navarra and the Centre for Applied Medical Research (CIMA) of the University of Navarra. Specialists from the Reina Sofa Hospital in Crdoba and the Institute of Human Genetics at the Schleswig-Holstein University Hospital, Kiel Campus in Germany also participated in the study and the publication of results.

It is notable that acute lymphoblastic leukaemia is the most common oncological illness amongst children. It makes up 25% of all cancers amongst paediatric patients and approximately 75% of cases of leukemia in infancy, although current survival rates in developed countries stand at about 75% of diagnosed patients.'/>"/>
