Predictive radiosensitivity network model

a network model and radiosensitivity technology, applied in the field of cancer treatment, can solve the problems of inability to capture and study the continuous nature of many phenotypic features in diseased and normal states, and the dynamics of network component interactions have remained mostly undefined, so as to facilitate the study of radiation response, improve the ability to define network dynamics, and improve the understanding of variables

Abstract

This invention is a model that simulates the complexity of biological signaling in a cell in response to radiation therapy. Using gene expression profiles and radiation survival assays in an algorithm, a systems model was generated of the radiosensitivity network. The network consists of ten highly interconnected genetic hubs with significant signal redundancy. The model was validated with in vitro tests perturbing network components, correctly predicting radiation sensitivity 2 / 3 times. The model's clinical relevance was shown by linking clinical radiosensitivity targets to the model network. Clinical applications were confirmed by testing model predictions against clinical response to preoperative radiochemotherapy in patients with rectal or esophageal cancer.
