Fall Hike in Frontenac Park

Saturday Oct. 26, 2019

A beautiful fall hike in Frontenac Provincial Park, on the southern edge of the Canadian Shield. We picked a perfect day for some fresh air, sunshine, exercise, and picnic! (Photo credits Pooja and Peter)

 
 

Congratulations Dr. Saeed Yazdi

Sept. 18, 2019

We gathered for another PhD defense celebration with Key lime pie - the third in 12 months. This one was in honour of Dr. Saeed Rismani Yazdi, our expert in microfluidics, who successfully defended in August. The pot luck was attended by the newly wedded Tyler and Lauren, who are in the process of moving to Toronto where Tyler will be a PDF in Jeff Lee's lab. It was also our opportunity to welcome to the lab two new Honours project students, Jenny Min and Emily Lind, and our new graduate student, Jordan Forbes. Welcome Jenny, Emily, and Jordan!

 

 

 

Congratulations Dr. Tyler Vance!

May 10, 2019

Tyler defended his PhD thesis with aplomb! and the entire Davies lab celebrated his success with GUSTO! A hearty dinner was topped off with Peter's specialty PhD Key Lime Pie, of course. #tradition Congratulations and all the best in Toronto, Dr. Vance!

 
 

Biochem Body Pump Challenge!

July 12, 2019

This was the 3rd of our 4-yearly Body Pump Challenges for the Biochem program. Great turnout ... but sadly, the Davies lab was just beaten on percent attendance by the Allingham lab. Well done Allinghammers! Thanks and congrats to all the pumpers, and thanks to super instructor Anna Coe and GoodLife for their support.

Lab Bowling Night

Jan. 21, 2019

Lab Bowling Night with colleagues from the 6th floor. Celebrity bowlers include: Midnight Cowboy, Falling Star, Marie Let Them Eat Cake, Cosmo Kramer, and Mitch Marner. Thank you to Social Convener Tyler for organizing indoor bowling on the coldest night of the year.

 
 

Brett at the Brooklyn

Nov. 8, 2018

Who purifies proteins and does PCR by day, and plays in a band by night? Why, Brett Kinrade - of course! Knowing how good his lab work is, we went to check out the music. He rocks at both!

 
 

Lab hike in Frontenac Park 

Sunday Nov. 4, 2018

We had lovely late fall weather for our 13-km hike around Slide Lake to enjoy Canadian Shield scenery.

Congratulations Dr. Christian McCartney!

October 19, 2018

Congratulations to Christian McCartney on the successful defense of his PhD thesis! We were honoured to have Dr. Yasuko Ono who came all the way from the Tokyo Metropolitan Institute of Medical Science in Japan to visit us and serve as Christian's external examiner. On the evening of the defense we gathered for a potluck dinner celebration, with scotch and sake tasting, and the traditional Key lime pie for the new Doctor of Philosophy.

 

 

Advances in Molecular Biology 2018 Symposium

Donald Gordon Centre, Queen's University

 

August 3 - 4, 2018

To celebrate Sherry Gauthier's semi-retirement after over 30 years as chief lab technician, mentor, and den mother, Peter organized a Symposium in her honour. Over 40 lab alumni travelled across the globe for this wonderful occasion - from Australia, New Zealand, Singapore, Switzerland, California, Tennessee, Ohio, British Columbia, Alberta, Quebec and Ontario! Four sessions of illuminating talks on topics ranging from tumour microenvironment to gene therapy, from wheat fungi to human microbiomes. The fun continued with a Davies Lab traditional croquet game complete with pink flamingos courtesy of Dr. Pliny Hayes. Family and friends joined the Friday dinner, and Sherry was deservedly serenaded and thanked and hugged for her help and support over the years. Saturday afternoon ended with a nostalgia tour of the sixth floor of Botterell Hall! Thank you to everyone for coming from far and wide for this memorable lab reunion celebration!

 

 

Tribute to Gordon H. Dixon

September 2018

 

Some background to “Protein Evolution Revisited” by Peter L. Davies* and Laurie Graham – published September 2018 (PMID: 30176752).

In recognition of the lifework of Dr. Gordon H. Dixon (1930/03/25 – 2016/07/24), two of Gordon’s former trainees - Rafael Oliva and Stephen A. Krawetz - commissioned a Special Issue of Systems Biology in Reproductive Medicine in his memory. Peer-reviewed papers were contributed by researchers who trained in the Dixon lab, or were collaborators. The modified preface to our review (below) also gives an insight into how we came to work on antifreeze proteins.

 

Peter Davies:  Gordon H. Dixon (GHD), one of my post-doctoral mentors, wrote an inspiring review on “Mechanisms of Protein Evolution” in the 1966 2nd edition of ‘Essays in Biochemistry’. It was written only thirteen years after the discovery of double helix DNA structure, at a time when the genetic code had just been deciphered, nucleic acid sequencing was tortuous, and protein sequencing was THE way to study gene variation and mutation. GHD was able to capture the emerging field of molecular biology in this article and illustrate how protein evolutionary mechanisms were being deduced from tiny amounts of data. I read “Mechanisms of Protein Evolution” as an undergraduate student at University of Wales, UK and was fascinated by the emerging links between protein divergence and the evolution of species. GHD’s review encouraged me to continue the study of biochemistry at the graduate level, which led in turn to a career in research.  In 1968, I was accepted into the graduate program in the Department of Biochemistry at the University of British Columbia, not realizing that GHD had moved there from Toronto. When I found out he was in the department I was told Gordon’s lab was full. Indeed it was crowded, and I remember at one point a post-doctoral fellow using the ultracentrifuge as a desk, hoping that the rotors were well balanced. I made many friends in his lab and followed their work on rainbow trout spermatogenesis, histone modification and protamine expression with great interest.

My opportunity to work with Gordon came in 1974 as a post-doctoral fellow when GHD returned to Canada from Sussex, UK to set up a new lab at the University of Calgary’s Medical School next to the Foothills Hospital. By this time it was realized that eukaryotic messenger RNAs had poly (A) tails and the isolation of protamine mRNA had been achieved and perfected in the GHD lab by Lashitew Gedamu. One of the collaborative projects that I worked on with Lashitew in Calgary was a study of the proteins bound to protamine mRNA that formed messenger ribonucleoprotein particles. My planned project as a new independent investigator and Assistant Professor at Queen’s University (Kingston, ON) in 1977 was an examination of messenger ribonucleoprotein particles in developing muscle. But a friendship formed at UBC with one of GHD’s graduate students, Choy-Leung Hew, changed all that. Choy had worked with Gordon on haptoglobins and was an expert in protein chemistry. He joined the faculty at Memorial University of Newfoundland in 1974, and soon after developed an interest in the recently discovered antifreeze proteins (AFPs) of marine fishes.  Choy recruited me to the study of AFPs to assist with the molecular biology aspects because I had gained experience in mRNA isolation, cDNA synthesis, and nucleic acid sequencing from my research with GHD in Calgary. It was a fortuitous transition as AFPs have been an extremely productive field for investigating protein structure-function relationships. However, some of the most fascinating insights about antifreeze proteins are those that relate to protein evolution - the theme of the review article GHD wrote over 50 years ago that is echoed here. Our review on protein evolution features examples from the field of antifreeze proteins, but with some parallels to protamines.

 

We are grateful to the Canadian Institutes of Health Research (CIHR), the Natural Sciences and Engineering Research Council (NSERC) and the Muscular Dystrophy Association (MDA) for funding our research.
