RNA-Seq of neuroblastoma Th-MYCN mouse model, samples sensitive to chemotherapy, and those with chemotherapy resistance

Some neuroblastoma patients relapse after chemotherapy. Here, a Th-MYCNCPM32 mouse model usually have spontaneously tumours which are sensitive to chemotherapy. By treating mice with consecutive cycles of sublethal cyclophosphamide (CPM) using a personal dose escalation protocol (PDE), resistant tumours may develop. This experiment aims to compare the expression profiles (RNA-Seq) of sensitive and resistant MYCN driven tumours in order to understand the mechanisms behind resistance. Samples also presented cross-resistance to vincristine and doxorubicin.
