Abstract C25: Targeting cancer stem cells using ALDH-dependent 5-nitrofuran pro-drugs
We hypothesise that cancer stem cells with high aldehyde dehydrogenase (ALDHhigh) activity present a new therapeutic target and will be selectively sensitive to 5-nitrofuran pro-drugs.Cancers are heterogeneous and contain subpopulations of ALDHhigh cells with tumour initiating potential. ALDH enzymes metabolize toxic aldehydes, and are highly expressed in somatic and cancer stem cells (CSCs), although their function in stem cells is not fully understood. In a small molecule screen coupled with target ID, we recently discovered that clinically active 5-nitrofurans (5-NFNs) are substrates of ALDH2 (Zhou et al., 2012). 5-NFNs...

Abstract C195: A Wee1 inhibitor analog of AZD1775 demonstrates synergy with cisplatin with reduced single-agent toxicity in medulloblastoma
Medulloblastoma is the most common primary brain tumor in children. Current treatment for medulloblastoma includes surgical resection, radiation and cytotoxic chemotherapy. Although this approach has improved survival rates, the high doses of chemotherapy required to circumvent drug resistance mechanisms and result in clinical efficacy often give rise to lasting neurocognitive defects, stunted growth, deafness, and even secondary tumors. Therefore, synergistic drug combinations that maintain clinical efficacy, but allow dose reductions of cytotoxic agents limiting their adverse effects would be an attractive approach for p...

Abstract A10: Functional characterization of Ewing's sarcoma susceptibility loci
Conclusions: In synopsis, our data indicate that the previously identified ES susceptibility regions and candidate genes may play a prominent role in ES pathobiology.
