TCG field trip in Belize

last modified Sep 01, 2016 11:13 AM

Punta GordaTwo TCG members, Alex Sampson and Andrea Strakova, have recently returned from a field trip in Belize. Alex and Andrea worked with vets and volunteers at the Hopkins Belize Humane Society (HBHS), Animal Medical Centre, Paw’s Veterinary Clinic, Roaring Creek Veterinary Clinic, Stann Creek Animal Hospital, Punta Gorda Humane Society and the Belize Wildlife & Referral Clinic to monitor the clinical behaviour of CTVT in a cohort of Belizean dogs. Huge thank you to Clara Lee Arnold from the HBHS and all of our fantastic collaborators who helped with the field work, and welcome back, Alex and Andrea.

The contagious cancer that conquered the world

last modified May 17, 2016 10:14 AM

Using genetics, scientists at the TCG show how the world’s oldest cancer “metastasised” through the global dog population in an article published today in eLife.

Thanks to dedicated help from our veterinary collaborators based all over the world, we collected and analysed canine transmissible venereal tumour (CTVT) samples collected from over 400 dogs in 39 countries across six continents. Our research showed how CTVT has rapidly spread around the world over the last two thousand years. By tracing the five genetic lineages, or “clades”, of CTVT tumours (see map below), we mapped the geographical routes that the tumour may have taken on its global travels. Excitingly, our work also showed how CTVT has captured, maintained and rearranged its mitochondrial DNA along the way.

If you would be interested in learning more about our recent work on CTVT, you can watch our short video or access the full paper.

Greetings from Mirjam after her visit to TCG

last modified Feb 23, 2016 11:19 AM

Last week (1st-5th February) I had the privilege of visiting the TCG group at the Department of Veterinary Medicine in Cambridge, UK.

I had an awesome week!


In my normal life I am a vet who works for a welfare organisation in Port Elizabeth, South Africa. I work in a small clinic where I deal with vaccinations, basic treatment of animal illness and injuries and simple surgery (predominantly spaying). I see and treat TVT regularly and since 2013 I have been sending biopsies to Andrea. Until now, sending regular biopsies was the extent of my involvement with the CTVT project. But after this week, I feel more like I'm part of a team!


Sitting in the lab in Cambridge and cutting up the pieces of tumour that I had actually collected, made me see how I fitted in the whole picture. From the way I label the biopsy vials, the information I send, the pictures I take to the point where I treat the patient. And in discussion with Liz and Tracy and Andy, I soon realised how little things that I can do (clinical history, location of the dog, exact treatment protocol etc) can make a considerable difference to how the results are interpreted.

I had been asked to do a presentation for the lab describing my field work. Initially I was wondering how I could relate to my audience but it turned out to be very easy to share my veterinary ideas and experiences with the group and for them to make suggestions about more field based information gathering. It all came together very nicely!


My very comfortable accommodation was at King's College, right in the heart of old Cambridge. The place oozes history and it's difficult not to be impressed by it.

The week wasn't just in the laboratory. I was given a guided tour of the Queen’s Veterinary School Hospital by the Dean of the Vet School Professor Mike Herrtage, I also went to other departmental presentations. We did lunch, we did dinner and it was over before I had a chance to breathe!


Liz, Tracy, Andy, Max, Young Mi, Adrian, Maire and Issy, thank you all for an unforgettable week!


Warm regards,


Dr Mirjam van der Wel from AACL, South Africa visited TCG

Dr Mirjam van der Wel, from Animal Anti-Cruelty League (AACL) South Africa, came to visit TCG last week. Mirjam is a collaborator of our ongoing CTVT projects and had sent us hundreds of CTVT samples in the past few years. She spent a week with TCG members and investigated the journey of CTVT tissue samples from the biopsy to genomic DNA sequencing. 

Mission completed! TCG members back from an exciting Tasmania field excursion

last modified Jan 28, 2016 11:12 AM

Over the past three weeks, our enthusiastic TCG members have been on a field excursion to Australia’s southernmost state: ’Tassie devil’s habitat. With the recent discovery of a second DFTD lineage, their intention was to conduct a preliminary field assessment of the spread DFT2 and meet local collaborators of the Save the Devil program.

Bringing Tasmanian summer, many unique memories and devil stories in
their suitcases, the three have now safely arrived in Cambridge: welcome back!

A second transmissible cancer in Tasmanian devils

last modified Jan 04, 2016 01:32 AM

Scientists at the TCG, together with collaborators at the University of Tasmania and the Save the Tasmanian Devil Program, have discovered a second transmissible cancer in Tasmanian devils. This second cancer, known as Devil Facial Tumour 2 (DFT2), causes tumours that are grossly indistinguishable from the first-discovered transmissible cancer in Tasmanian devils (now known as DFT1). However, DFT2 bears no detectable genetic similarity to DFT1. This astonishing discovery has just been published in Proceedings of the National Academy of Science. Further information is also available on the University of Cambridge website.

A third transmissible cancer found in clams

last modified Apr 16, 2015 09:44 PM

Contagious cancers may be more common than expected - researchers from Columbia University have just discovered a third transmissible cancer, affecting soft-shell clams on the East Coast of North America. Clam disseminated neoplasia, a leukemia-like disease, has been known for years and was previously thought to be caused by a virus; but now it is clear that it is transmitted by the cancer cells themselves. To celebrate the discovery of a new infectious cancer, we tested out the clams in a local restaurant…
