Biography

Dr. Graham Pidgeon graduated from DCU with a degree in Analytical Science and obtained a Ph.D. in Cancer Research from the Dept. Surgery, RCSI/DCU in 2000. Awarded an American Cancer Foundation Fellowship, he worked as research fellow at Wayne State University, Michigan with Prof. Kenneth Honn on the regulation of prostate cancer survival by bioactive lipids. In 2002 he returned to Ireland as a senior postdoctoral fellow in the Dept. Clinical Pharmacology at RCSI. He was awarded a HRB postdoctoral fellowship in 2004, and joined Dr. Ken O'Byrne in the Thoracic Oncology Research Group at the Institute of Molecular Medicine at TCD/St. James as research lecturer. He developed his own research group focused on the regulation of VEGF-mediated survival pathways by COX and LOX in lung cancer and combining inhibitors of these pathways with conventional chemotherapy. He was appointed senior lecturer in Dept. Surgery at TCD/St.James in Jan 2007 and has expanded these research areas into other prevalent solid malignancies, including oesophageal cancer. He has published in a number of high impact journals including Cancer Research and Circulation, and was awarded the IJS doctor award 2005 for Cardiology. His current research is focused on the role of bioactive lipid enzymes including cycloxygenase and lipoxygenase in the growth and metastasis of lung and oesophageal cancer. Dr. Graham Pidgeon's group have a strong interest in the molecular processes regulating the growth and survival of oesophageal and lung cancer. Work in the past months has concentrated on the development of an adipose biobank from patients undergoing oesophageal and colorectal resections, to investigate the role of visceral fat in the progression of these malignancies. Recent scientific literature highlights the importance of central obesity and metabolic syndrome (MetS) as negatively impacting on cancer risk, tumour size, metastatic potential, and both disease free and overall survival. The group are prospectively investigating the incidence of central adiposity, metabolic syndrome and adipocyte secretion amongst newly diagnosed patients with these cancers to determine the link between these parameters and tumour size, metastases, treatment pathways, and survival.

Research Expertise

Description

My research interests focus on the regulation of vascular function and angiogenesis by bioactive lipids/prostanoids. Biologically active products derived from cyclooxygenase (COX) and lipoxygenase (LOX) mediated metabolism of arachidonic acid are involved in a range of clinical conditions, including arthritis, cancer and heart disease. One area of my research is in the examination of the role of the different COX isoforms, and their downstream products in pulmonary disease. There are reports that drugs which selectively inhibit COX-2 have detrimental effects on cardiac function, to date our results confirm that selective inhibition of COX-2 in models of hypoxia-induced pulmonary hypertension aggravates the problem. We are currently examining the mechanisms whereby cyclooxygenase isozymes regulate pulmonary hypertension and lung cancer, with an emphasis on COX-mediated angiogenesis and thrombosis in these diseases. A second area of research involves examining the role of bioactive lipids as survival factors in cancer. We are currently examining the role of 12-lipoxygenase, COX-2 and thromboxane synthase as survival factors in lung cancer and mesothelioma. The goal of this research is to identify the mechanisms whereby these enzymes facilitate tumour survival under conditions found within the tumour microenvironment, including hypoxia and serum deprivation. My third area of research interest is in the Vascular Endothelial Growth Factor receptors and their expression in lung cancer and mesothelioma. I am particularly interested in the Neuropilin family of receptors, their role in cell survival and regulation by bioactive lipids. We are currently examining the expression profile of VEGF receptors in cell lines and retrospective human lung cancers, to correlate their expression with tumour grade and stage.

Projects

  • Title
    • An investigation of the thromboxane and prostacyclin synthase pathways in non-small cell lung cancer.
  • Summary
    • This research project will provide significant insights into the potential mechanisms whereby the balance between the expression of thromboxane synthase and prostacyclin synthase in lung cancer may confer a survival advantage on tumour cells directly. The series of experiments will examine the potential correlation between tumour expression of these PGH2 metabolising enzymes and clinical parameters, including thrombotic events, tumour angiogenesis and overall survival. These pathways have been implicated in various forms of malignancies and a number of specific inhibitors of TXS have shown promise in clinical trials, suggesting the translation of the research proposed here into future clinical applications in lung cancer should be rapid. The in vitro experiments are carefully designed to explore the potential survival mechanisms at the cellular protein level, by generating NSCLC clones with overexpression or silenced expression of these targets using molecular strategies. These clones will be thoroughly characterised both invitro and invivo for their effect on tumour cells. Direct clinical relevance will be highlighted by retrospectively examining the expression of TXS and PGIS expression in a series of resected lung tumours with varying stage and type of disease and also in frozen normal / tumour samples taken from the EU biobank at St. James Hospital. By furthering our knowledge of these critical regulatory mechanisms controlling tumour cell survival, it is anticipated that new interventional therapies may be designed to target lung cancer, either alone or in combination with conventional radiotherapy and chemotherapy.

  • Title
    • Neuropilin-1 expression and regulation by 12-Lipoxygenase in lung cancer.
  • Summary
    • This research project will provide significant insights into the potential mechanisms whereby neuropilin-1 expression in lung cancer may confer a survival advantage on tumour cells directly. The series of experiments will examine the potential correlation between tumour expression of the arachidonic acid metabolising enzyme 12-LOX and neuropilin-1 receptor expression in lung cancer. Each of these pathways have been implicated in various forms of malignancies and a number of specific inhibitors of LOX pathways have shown promise in clinical trials, suggesting the translation of the research proposed here into future clinical applications in lung cancer should be rapid. These experiments are carefully designed to explore the potential survival mechanisms at the cellular protein level, by overexpression of 12-LOX while targeting NRP-1 pathways by a neutralising or RNA silencing approach. Direct clinical relevance will be highlighted by retrospectively examining the expression of 12-LOX and NRP-1 expression in a series of resected lung tumours with varying stage and type of disease. By furthering our knowledge of these critical regulatory mechanisms controlling tumour cell survival, it is anticipated that new interventional therapies may be designed to target lung cancer, either alone or in combination with conventional radiotherapy and chemotherapy.

  • Title
    • COX-isoforms and prostaglandins in an hypoxia-induced model of pulmonary hypertension.
  • Summary
    • Altered regulation of the cyclooxygenase (COX) signalling pathway underlies the development and progression of many diseases. The PGI2/TXA2 ratio is of particular importance in-vivo, with the corresponding synthases being shown to be differentially regulated. COX-derived prostanoids have been implicated in the development of PH, and an imbalance between the generation of thromboxane A2 (TXA2) and prostacyclin (PGI2) has been reported in both primary and secondary forms of the disease. These prostanoids have directly opposing effects; PGI2 is a potent vasodilator, is anti-proliferative, and inhibits platelet activation and aggregation, while TXA2 is a vasoconstrictor, is mitogenic and activates platelets and their aggregation. COX-2 is the main isoform responsible for the generation of PGI2, while TXA2 is mainly derived from platelets, where COX-1 is the main isoform. Exogenous PGI2 is effective in reducing pulmonary vascular resistance in some forms of human pulmonary hypertension (PH). To examine whether endogenous prostanoids played a similar role in PH, we examined the effect of deleting COX-gene isoforms in a chronic hypoxia model of the disease. An experimental model of pulmonary hypertension (PH) was generated using COX-gene disrupted mice. PH was induced by 3 weeks of hypobaric hypoxia, and was confirmed by direct measurement of right ventricular end systolic pressure (RVESP), right ventricular hypertrophy (RVH) and increased haematocrit. RVESP was increased in wild-type (WT) hypoxic mice compared to normoxic controls, while COX-2 knock-out (KO) mice showed a further increase in RVESP following hypoxia. Urinary TXB2 excretion increased following hypoxia, an effect that was exacerbated following COX-2 gene disruption. In contrast, the increase in 6-keto-PGF1á excretion following hypoxia was reduced by COX-2 gene disruption. Tail-cut bleed times were reduced following hypoxia, and there was (immunohistochemical) evidence of intravascular thrombosis in lung vessels that was exacerbated by disruption of COX-2 and reduced by deletion of COX-1. The thromboxane receptor antagonist, ifetroban (50mg/kg/day) offset the effect of COX-2 gene deletion, by attenuating the hypoxia-induced rise in RVESP and intravascular thrombosis. In addition to pulmonary vascular thrombosis, a second characteristic feature of pulmonary hypertension is the development of pulmonary vascular remodelling an angiogenesis. Real-time PCR analysis of vascular remodelling in the disease implicated a number of genes to be altered in the disease including VEGFC, EphB2, TNFá, TNFaip2, and CCl2. Genes of particular interest included VEGFC, EphB2, TNFá and TNFaip2, which are all pro-angiogenic factors that were down-regulated following COX-2 gene disruption. Further work is required to determine whether these changes in gene expression profile represent a beneficial or detrimental adaptation to chronic hypoxia exposure. In conclusion, the findings of this research demonstrate that COX-2 gene deletion exacerbates the pathogenesis of pulmonary hypertension, enhances sensitivity to TXA2 and induces intravascular thrombosis in response to hypoxia. COX-2 gene deletion also down-regulated the expression of a number of angiogenic genes in response to hypoxia, suggesting that expression of these genes may have a beneficial effect in the pathogenesis of the disease. Our data provides evidence that endogenous prostanoids modulate the pulmonary response to hypoxia.
