Abstract

Differences in the microRNA (miRs) signature and functional studies of genes associated to cancer could help in diagnosis, prognosis and suggest new insights in important pathways that could be used as potential therapeutic targets in human malignancies. The aim of this project is to identify miR signatures in different pediatric tumors (acute lymphoblastic leukemia, central nervous system tumors and adrenocortical tumors) and to evaluate the differential miR profile in specific subgroups of these malignancies and also to study the function of genes identified in previous group studies, with potential to be used as therapeutic target in new therapeutic protocol design, especially in poor prognosis patients. Functional studies will be made by silencing and/or activation of selected genes by assays of citotoxicity, cell viability and proliferation, apoptosis and cycle cell, and will include the genes SHOC2 and XPO7 in acute lymphoblastic leukemia cell lines, TNFA and AURKB in adrenocortical tumor cell lines, and VEGF and CA12 in astrocytic tumors and medulloblastoma cell lines. Until now the tumor bank of the participant institutions had stored more than 200 acute lymphoblastic leukemia samples, 60 of children adrenocortical tumors, 15 adult adrenocortical tumors, 50 meddulloblastomas, 50 pilocyticc astrocytomas, 50 glioblastomas as well as non-neoplastic control samples (bone marrow, adrenal and brain tissues).
