About the Project
Our previous studies established high-throughput genome-wide CRISPR screens which identified novel role of chromatin associated proteins in promoting drug resistance in ER+ breast cancer cells in their absence [1,2]. One such class of proteins are chromatin architectural proteins which mediate long range chromosomal interactions to regulate gene expression. Our CRISPR screens identified these proteins in promoting response to ER targeting agents in breast cancer cell lines. Interestingly, these complexes are mostly inactivated by mutations in metastatic breast cancers which supports the significance of our study.
By utilising systematic and unbiased methods (next generation sequencing and quantitative proteomics) in clinically relevant in vivo systems, this PhD project is proposed to discover the role of frequently represented alterations in chromatin architectural proteins in mediating drug resistance and the potential impact of epigenetic inhibitors in overcoming resistance to the existing therapies in breast cancers. This study will provide mechanistic insights and the importance of epigenetic proteins in driving tumour relapse and potential therapeutic strategies to target these aggressive tumours.
Candidates are expected to hold (or be about to obtain) at least a bachelor’s (Honours) degree with a minimum Upper Second class (or the overseas equivalent) in a relevant subject area. Candidates with experience in molecular biology techniques, next generation sequencing and CRISPR platforms are encouraged to apply. Additional expertise in bioinformatics approaches is desirable. A keen interest in studying gene regulatory mechanisms and epigenetics is essential.
