Taking apart pediatric cancer bit by bit
Cancer is an elusive beast. The staggering spectrum of presentations and the diversity between and within patients make even the very definition of the disease (types) a challenge. We build upon decades of painstaking clinical and basic research. The tools are now available to go deeper than ever before and to dissect the molecular characteristics at the heart of cancer development, progression, and cure. It is our declared aim to utilize these tools to gain a better understanding of the mechanisms underlying different types of pediatric cancers and to use these insights to inspire new diagnostic and therapeutic approaches. We aim to:
- Discover molecular features of aberrant cells and disease states that serve as biomarkers for better diagnosis, prognosis, and patient stratification
- Identify regulators and pathways involved in disease development and progression that may be targeted with inhibitors to inspire better treatment
- Boost effective use and re-use of multi-omics technologies and data resources by developing intuitive and assisted analysis tools powered by A.I.
Approach Our research combines high-throughput analysis of clinical samples with computational, statistical, and machine learning methods to dissect the molecular framework of pediatric cancers. Some of the methods we use include:
- High-throughput assays (“next-generation sequencing” for transcriptomic and epigenomic analysis, proteomics, imaging) on clinical samples and cell lines to compile comprehensive catalogs of the molecular features of cancer
- Integration and interrogation of public data sources such as repositories of molecular signatures of healthy and cancer samples as well as affected pathways to rationalize pathobiology
- Supervised and unsupervised dissection of data collections using statistical analysis and machine learning
- Development of user-friendly software to streamline common analysis tasks and to empower experimental researchers with visual analytics and assisted discovery of features of interest
