Pancreatic Cancer

Pancreatic Cancer Research Programme

The pancreatic research programme focuses on understanding the molecular mechanisms of drug resistance, invasion and metastasis in pancreatic cancer, in collaboration with Dr. Ray McDermont, Dr. Niall Swan and the surgical team at St. Vincent's Hospital and Dr. Gerard McVey and Prof. Michael Moriarty at St.Luke's Hospital.

Key areas of research involve:

  • Understanding the biology of invasion and metastasis through differentially regulated proteins/genes altered in an in vitro pancreatic cancer cell invasion model.
  • Examining the role of novel invasion-related markers identified through proteomic, microarray and miRNA analysis.
  • Evaluating targeted therapies in combination with radiotherapy and conventional chemotherapy for the treatment of pancreatic cancer.
  • Investigating the basis of drug resistance in pancreatic cancers through multidrug resistance markers.
