Investigator II

Dr. Laura Ailles

Dr. Laura Ailles and her team are focusing on two major research areas:

1. Intra-tumoural heterogeneity.
One focus is the identification and characterization of tumour-initiating cells (TICs) in solid tumours and the relationship between TICs and clonal evolution. The team also studies the role of cancer-associated fibroblasts in promoting malignant behaviours such as stemness and invasion. The cancers studied are head and neck squamous cell carcinoma, high-grade serous ovarian cancer and clear cell renal cell carcinoma.

2. Epigenetics in clear cell renal cell carcinoma (ccRCC).
The team is using primary patient-derived cultures and xenografts to gain a deep understanding of the epigenetic deregulation occurring in ccRCC, including identification of downstream effects on target genes and pathways and identification of small molecules with rapid clinical translational potential.
