Dr. Hernández Losa is Director of Molecular Biology Laboratory in the Department of Pathology from the Vall d´Hebron Hospital in Barcelona. He has trained in Cancer Research, focusing on the signaling and virus detection pathways in FFPE human samples at the Department of Pathology in Hospital Puerta de Hierro (Madrid). After his Ph.D. in Biochemistry and Molecular Biology, he moved to Vall d´Hebron Hospital endorsing extensive experience in drug synergisms in different in vitro models of breast and pancreatic cancer, also in the field of biomarkers, being today one of the reference laboratories in Molecular Pathology. In addition in the last five years, the laboratory has validated by immunohistochemistry more than 12 prognostic and/or predictive markers of cancer. Thanks to these molecular analyzes based on real-time PCR and NGS have contributed to the selection of patients for the different clinical trials carried out at our institution. Dr. Hernández-Losa has been also involved in different technologies validation for mutational analysis of KRAS, NRAS, BRAF, PIK3CA, and EGFR genes in samples from colorectal cancer and NSCLC patients, as well as in exosome samples obtained from primary tumors.
