Research

We have three main areas of research: (i) the role(s) of the RZZ complex in mitotic checkpoint regulation and (ii) the role of the mitotic checkpoint in mitotic catastrophe (iii) cell cycle kinases Wee1 and Myt1 synthetic lethality in breast cancer. 

(i) The RZZ complex consists of three proteins, Rod, Zw10 and Zwilch. They are kinetochore proteins that recruit the microtubule motor, dynein/dynactin, to kinetochores but were found to be also essential for the mitotic checkpoint. The RZZ complex is essential for the recruitment of the mitotic checkpoint effector Mad2 to kinetochores. The exact mechanism is still unknown. We are using molecular, biochemical and cell biological approaches to study the structure and function of the mitotic checkpoint apparatus in order to understand the underlying mechanism. (ii) Mitotic catastrophe is a cell death phenomenon that has been observed, however, there is not a molecular marker and the mechanism of action is not known. We are following up on the findings that genotoxic treatments of cancer cells often result in checkpoint adaptation and ultimately mitotic catastrophe. We have observed that prolonged mitotic arrest and centromere fragmentation often accompany mitotic catastrophe. We are examining the role of the mitotic checkpoint in this cell death process. (iii) Wee1 and Myt1 are cell cycle kinases that mediate inhibitory Cdk1 phosphorylation. In addition to being important for regulating the G2/M checkpoint, they are also essential for inhibiting Cdk1 activity at the end of mitosis. MK-1775 is a small molecule inhibitor of Wee1 kinase activity and is currently undergoing Phase I/II clinical trial for multiple cancers. We have identified the Myt1 kinase as a resistance factor for MK-1775 in breast cancers. We are examining the mechanism of Myt1 function in mediating MK-1775 resistance.

Research opportunities

Research training is available for undergraduate summer students, undergraduate research project students (398, 399, 498, 499 courses), undergraduate co-op students, graduate students and post-doctoral fellows. Individuals interested in graduate work in Oncology in my laboratory should have a strong background in molecular biology, biochemistry and/or cell biology, since research projects typically involve the use of platform technologies from these disciplines. Funding for students and fellows is available through application to competitive agencies (e.g., Alberta Innovates, CIHR, NSERC, Alberta Cancer Foundation, CRINA) or from operating grants to the Chan research program.

ONCOL 570 - Directed Reading in Experimental Oncology

Reading and discussion of current research literature on selected topics in experimental oncology under the direction of one or more faculty members. Topics presently available include cell adhesion mechanisms, cell cycle regulation, DNA repair, radiotherapy and susceptibility and resistance, oncogenes/tumor suppressor genes, and tumor cell metastasis. Notes: (1) Grades will be based on participation in group discussions and/or written reports from assigned readings with emphasis on critical evaluation of the subject matter. (2) Students in other graduate programs may register with the consent of Instructors. Prerequisite: consent of Department.

The role of the GCC is to uphold standards of academic excellence within the specialization and the program.

• To set regulations for students within the specializations (including course requirements)
• To select students for admission to the program
• To assist in facilitating appropriate supervisor-student pairings
• To ensure that the students’ supervisory committees are struck within one year of commencing the graduate program
• To review the membership of supervisory committees, Ph.D. candidacy examination committees, and M.Sc. and Ph.D. thesis committees
• To ensure that each supervisory committee meets at least once a year
• To monitor the progress of graduate students within the specializations by annual review of the FGSR Student Progress Report form
• To make recommendations, in consultation with the supervisor, for the appropriate action in the event that a student fails a course or courses
•  For the Cancer Sciences specialization, to provide constructive feedback to the students on their Ph.D. proposals and make recommendations to the supervisor and supervisory committee regarding the suitability of the candidate, the approach and the project for a Ph.D. degree
• To facilitate career development of graduate students
• To act as the interim supervisor for rotational students, and for students who are without a supervisor
