Tumor irradiation during cancer treatment induces cell death by apoptosis, mitotic death, and clonogenic death. With expanded global access to cancer radiotherapy, there is a need to discover agents with anti-cancer and radiation sensitizing properties. in vitro high-throughput screening (HTS) systems routinely used to screen agents for cytotoxicity assays unfortunately do not directly measure clonogenic potential and fail to accurately predict the efficacy of an agent either in subsequent preclinical animal model testing or in clinical trials. Clonogenic assays unlike colorimetric and metabolic assays for determining cell viability and apoptosis, are less susceptible to artifacts. We are addressing these requirements through an integrated I-PARTS platform development and optimization. Here, the design and the prototype of a fully enclosed imaging/X-ray irradiation system will be presented. The proof of principle experimentation to obtain high content information on the cellular response to specific primary human cells (normal or tumors) to a variety of radiation doses and fraction modality will be described. The initial approaches taken towards the establishment of an integrated platform to screen anti-cancer drugs will be discussed.
