Abstract
- Loss of functional DNA repair pathways is a common occurrence in cancer cells and discovery of novel drugs that selectively kill repair deficient tumors cells could identify new cancer therapies. In this work we describe the use of high-throughput screening to determine chemicals that sensitize cells deficient in the fanconi anemia protein, FANCD2. Cell growth of human fibroblasts proficient (PD20+D2) and deficient (PD20) for FANCD2 were screened using two libraries containing over 1000 bioactive compounds and kinase inhibitors. The cells were treated with compounds continuously for 3 days and cell growth was assessed using a luciferase-based assay measuring ATP levels. The initial screen identified numerous compounds inducing differential survival in cells with and without FANCD2 and follow-up testing will be required to confirm these potential hits. However, it is promising that, in addition to novel compounds, several crosslinking agents, including mitomycinC, which are known to sensitize fanconi anemia cells to cell death are among the positive hits. Our results validate chemical screening as a tool to discover potential new cancer therapies targeting repair deficient cells lines. In addition, other than their role in crosslink repair, there is still not much known about the fanconi anemia protein family and the discovery of novel compounds involved in FANCD2 dependent cell survival could lead to the discovery of new functions of this protein family.
