Research

The overarching research questions of our group are (i) to identify novel therapeutic targets in cancer and (ii) to decipher the genetic and epigenetic mechanisms of oncogene and tumour suppressor regulation.

Recent publications revealed that only 1-2% of the human genome encodes for proteins but as much as 75% of the genome can be transcribed. These non-coding transcripts comprise the majority of RNA molecules in the cell and bear exciting potential to pursue as therapeutic targets and biomarkers. Our group investigates the role of long non-coding RNAs (lncRNAs), the largest and most diverse class of non-coding transcripts. We focus on metastatic breast and colorectal cancer and glioblastoma, as these types of cancer are major health concerns in New Zealand and world-wide. Our research combines bioinformatics, CRISPR/Cas9 genome editing, cancer biology, single-cell and spatial transcriptomics and preclinical research using patient-derived organoids and mouse models. In addition to translational research, we are interested in studying the molecular mechanisms by which lncRNAs act in the cell and exploring the RNA interactome.

Current research projects include:

  • Identifying novel lncRNA oncogenes and tumour suppressors using CRISPR screens.
  • Developing nucleic acid therapeutics to target lncRNAs in cancer, as monotherapies and in combination with standard-of-care.
  • Elucidating the molecular mechanism of lncRNAs in the cell, with particular interest in cancer metabolism and global transcription and translation changes.
  • Studying the impact of lncRNAs on tumour evolution.
  • Investigating the RNA interactome and structurome in cancer.
  • Identifying new lncRNAs and circRNAs as biomarkers.
  • Translational research models such as patient-derived organoids
