The sarcoma research group of the Bellvitge Biomedical Research Institute (IDIBELL), led by Dr. Òscar Martínez-Tirado, has identified a potential new therapeutic target for Ewing sarcoma, the second most frequent bone cancer in children and adolescents, and a tumor known by its aggressiveness and tendency to metastasize. The research, published in International Journal of Cancer, has been funded almost entirely by the Alba Pérez Foundation, a non-profit organization dedicated to this disease.

For years, the main line of research of the Ewing sarcoma group focused on the caveolin 1 protein (CAV1), which has been associated to treatment resistance and metastasis, among other issues. However, the location of this protein in the cell makes its use as a therapeutic target virtually impossible. “That is why we were looking for a CAV1 cofactor with an equally relevant role but a more accessible location”, explains Dr. Martínez-Tirado, “and the EphA2 membrane receptor, already described in previous studies, meets these requirements.”

In their latest work, researchers not only demonstrate the connection between the EphA2 receptor and caveolin 1, but also establish a correlation between the phosphorylation of EphA2 and the aggressiveness of tumors in
