McEwen Researchers Identify a New Role for CK2 and p27 in Cardiomyocyte Hypertrophy


The p27-CK2 interaction is important for cardiac growth controlA recent study from Dr. Rudiger von Harsdorf’s laboratory, published in Nature Genetics in March 2008, demonstrates a functional link between the protein kinase CK2-alpha and p27, a cancer-related cell cycle inhibitor. The study reveals how this interaction may mediate the hypertrophic growth of cardiomyocytes.

Using a combination of cell culture studies and p27 knockout mice, they report that p27 inhibits hypertrophic growth in adult cardio-myocytes. CK2-alpha phosphorylates p27 in response to hypertrophy, eliminating the inhibitory influence of p27 on CK2-alpha. Unphosphorylated p27 acts to suppress hypertrophy and cardiac growth, as demonstrated using p27 knockout mice treated with the growth factor angiotensin II, or with surgical banding, a model for severe hypertension.

These findings suggest a critical role for CK2-alpha and p27 in cardiac growth control, and their interaction may be important in the discovery new therapeutic interventions for heart failure.

Protein kinase CK2 links extracellular growth factor signaling with the control of p27(Kip1) stability in the heart. Hauck L, Harms C, Rohne J, Gertz K, Dietz R, Endres M, von Harsdorf R. Nat Med. 2008 Mar;14(3):315-24. [Abstract]

John Dick Honoured with AACR G.H.A. Clowes Award


John DickMcEwen researcher Dr. John Dick is the 2008 recipient of the AACR G.H.A. Clowes Award, an award given to a researcher in recognition of outstanding accomplishments in basic cancer research.

The award acknowledges Dr. Dick's work on leukemia pathogenesis, hematopoietic stem cell biology, and the discovery of cancer stem cells in leukemia.

Dr. Dick will be presented with the award at the upcoming AACR meeting in San Diego, CA (April 12-16).

Shaf Keshavjee Awarded Wyeth Pharmaceuticals/CIHR Rx&D Clinical Research Chair


Shaf KeshavjeeDr. Shaf Keshavjee was awarded one of two Wyeth Pharmaceuticals/CIHR Rx&D Clinical Research Chairs in Transplantation for his work entitled “Ex-vivo Gene Repair of Injured Donor Lungs for Transplantation”.

In partnership with the CIHR/Rx&D Clinical Research Program, Wyeth has set up the Chairs to promote research in transplantation and to develop multidisciplinary approaches to studying the long term effects of organ transplantation.

Molly Shoichet Receives Prestigious Killam Research Fellowship


Molly ShoichetDr. Molly Shoichet was awarded a Killam Research Fellowship in Chemical Engineering from the Canada Council for the Arts for her proposal entitled “Three Dimensional Presentation of Immobilized Growth Factors to Guide and Control Cell Differentiation”.

Ten Killam Research Fellowships are awarded each year to support scholars involved in research of outstanding merit in the humanities, social sciences, natural sciences, health sciences, engineering and interdisciplinary studies within these fields.

Grants Awarded


Congratulations to McEwen investigators Drs. Ren-Ke Li, Andras Nagy and Thomas Waddell for their successful applications in the latest round of CIHR operating grants. Dr. Waddell’s application was ranked first by the Respiratory System Committee.

Kudos also to Drs. Michael Fehlings and Rudiger von Harsdorf for their successful applications to the Heart and Stroke Foundation.

Special honours to Dr. Fehlings who was also awarded a 21st Century Grant from the Cervical Spine Research Society, and received a one-year renewal from the Christopher Reeve Foundation.

Gordon Keller and Andras Nagy Discuss the Future of Stem Cell Research at Cafe Scientifique


Cafe ScientifiqueA large crowd of various ages and backgrounds discussed the future of stem cell research with Gordon Keller and Andras Nagy at the Duke of York pub on February 13, 2008.

Following presentations from Drs. Keller and Nagy and lawyer Vanessa Grant describing the current status and law regarding stem cell research in Canada, the floor was opened up for questions.

The cozy atmosphere enabled a lively discussion with questions ranging from the use of stem cells in performance enhancement for athletes to cost-benefit issues to stem cells offering eternal life.
