Prof. RUDD John Anthony (陸臻賢) worked with Glaxo Group Research in the late 1980s to explore the potential use of the 5-HT3 receptor antagonist, ondansetron, to antagonize chemotherapy- and drug-induced emesis.  He was also part of a team that mapped 5-HT3 receptor distribution in the human and ferret brainstem and first to show increases in of 5-HT in the plasma of patients receiving cisplatin-based chemotherapy.  Pioneered the use of the ferret to model chemotherapy-induced acute and delayed emesis (now a gold standard model) and discovered that NK1 tachykinin antagonists could be used to prevent the acute and delayed phases of emesis induced by cisplatin: now NK1 tachykinin antagonists are a cornerstone of treatment for delayed emesis.  Recently he collaborated with Helsinn on the development of the second generation 5-HT3 and NK1 receptor antagonists, palonosetron and netupitant, respectively.  He has an ongoing interest in broad inhibitory antiemetic drugs and works with several leading pharmaceutical companies to aid drug development.  He is serving concurrently as the Director of the Laboratory Animal Services Centre, The Chinese University of Hong Kong.

  2. Understanding mechanisms of gastric dysrhythmia following anticancer treatment; interstitial cells of Cajal (ICC); value of prokinetic drugs.
  3. Understanding mechanisms of cancer cachexia; development of meaningful animal models.
  4. Role of forebrain to brainstem mechanisms controlling feeding and homeostasis and behaviors indicative of nausea; emetic liability mechanisms. 
  5. Mechanisms of taste and smell alterations during chemotherapy.
