Our workplace is participating in Plaid for Dad in support of Prostate Cancer Canada! Leading up to Father’s Day, let’s all wear plaid to work on Friday, June 14th to help raise funds and awareness for prostate cancer; all in the name of helping dads across Canada! Take a photo of your workplace colleagues dressed in Plaid on June 14th and send it to me (Perrin at email@example.com) and I will post it on the APCaRI blog!
Please make a donation and get involved. You can make a secure online donation now on our workplace campaign webpage using your credit card. Click here to go to the Team Nanostics donation page.
Also, take a couple of minutes to check out www.plaidfordad.ca, Hill Street Beverage Company, IndoChino, and Head/Penn (SportChek) if you like non-alcoholic beer, suits or tennis, respectively. These businesses will donate to PlaidForDad with the purchase of certain products!
Thanks – I’m looking forward to seeing you all in plaid on June 14th!

Konstantin Stoletov and Lian Willetts co-first-authored an article published recently in Nature Communications titled “Quantitative in vivo whole genome motility screen reveals novel therapeutic targets to block cancer metastasis“. These two researchers, along with fellow Lewis lab members and collaborators from the University of Calgary and Vanderbilt University set out to determine what genes and signaling networks are involved in the rate-limiting steps of solid tumour cell motility, in vivo. But the team was hampered by the lack of an effective, quantitative, in vivo imaging platform. They wanted to visualize the movement of tumour cells, or lack of, in real-time AND use this intravital imaging platform to screen a large bank of tumour cells harboring single gene mutations for cells that show a loss of motility.
When tumour cells metastasize they get into (intravasate) the hosts’ bloodstream and use the vascular system like roadways to travel throughout the body. This lets the tumour cells colonize new microenvironments where they will proliferate and form new tumours. So metastatis is really dependent on tumour cell motility. Although there are many different types of solid tumours known, previous research suggests that if the tumour cells can mobilize and metastasize then the expressed motility-related genes share homology across tumour types. This is great news because it would mean that therapeutic targets aimed at stopping motility could also stop metastasis for many tumour types!
The Lewis lab researchers and their collaborators developed an in vivo, fluorescent, time-lapse screening platform that uses shell-less avian embryos for tumour growth and formation. The avian embryo is an excellent tumour model because the tumour cells will grow on the chorioallantoic membrane in a single cell layer, making in vivo cell motility imaging actually doable.
Using this platform the team screened over 30 000 human genes for the ones needed for cell motility and ultimately found 17 genes that looked to be effective metastasis-blocking gene targets. Stoletov, along with other Lewis lab members, are continuing this research by studying these 17 attractive candidates further to determine which one (s) would make therapeutic metastasis-blocking targets.
