Seeking new targets to prevent drug resistance and metastasis
Ongoing studies are focused on understanding the interplay between environmental (external) and endogenous(internal) factors that promote cancer.
These efforts may aid the development of new predictive tools to match the right drug to each patient and improve patient outcomes.
The diversity of genetic changes within breast cancer is a feature associated with poor clinical outcome. Intra-tumor heterogeneity (ITH)–the existence of multiple subpopulations of tumor cells with distinct genomic profiles– is the consequence of this genetic diversity. Research suggests that ITH occurs during the emergence of drug resistance and that patterns of diversity within breast cancer and other tumor types correlate with poor clinical outcome.
Dr. Swanton's BCRF research is focused on understanding the mechanisms that lead to the generation of tumor diversity and cell-to-cell variation with the goal of identifying and modelling drivers of genome instability in breast cancer.
Ongoing efforts will study: 1) the cancer causing effects of environmental compounds; 2) mitochondrial DNA as a biomarker of malignancy; 3) the effect of aneuploidy–an abnormal number of chromosomes in a cell–on the development of normal and cancer tissues; 4) causative genetic factors of premature ovarian insufficiency–a loss of normal ovarian function before age 40.
These efforts may help develop new predictive tools to enable the optimal selection of breast cancer patients for defined therapeutic approaches.
The Translational Cancer Therapeutics (TCT) Laboratory is focused on identification of mechanisms of cancer evolution and its impact on drug resistance and patient stratification. Professor Swanton and his colleagues are using parallel clinical trial and integrative functional genomics approaches to develop new predictive tools to enable the optimal stratification of patients for defined therapeutic approaches. Through work aimed at identifying therapeutic approaches to target distinct patterns of genome instability, the TCT laboratory has demonstrated that chromosomal instability in colorectal cancer is initiated through DNA replication stress. The laboratory is now focusing on 1) a greater understanding of the molecular basis of the origins of intratumor heterogeneity, with a principal focus on Structural and Numerical Chromosomal Instability in solid tumors such as breast cancer in order to attempt to limit the acquisition of multi-drug resistance and treatment failure and 2) an in-depth understanding of the prevalence and prognostic impact of intratumor heterogeneity.
