Dr. María Verónica Brignone is a Vet from Argentina, who has collected CTVT tumour biopsies from dogs in Argentina and hosted a visit from a TCG PhD at Argentina previously. During her 2 weeks visit in September, Maria extracted genomic DNA from these CTVT samples and performed PCR analysis for genetic analysis to determine how CTVT in Argentina differs from CTVT tumours collected from other countries. Maria also gave a very interesting presentation of her work at TCG lab meeting and went on our Annual TCG punting trip with us!

We are very pleased that Maria enjoyed her visit at Cambridge and wish we will continue to collaborate with her and her colleagues at Argentina in the future!

Many congratulations to Adrian Baez-Ortega's new paper published on Science 2nd August 2019!

This summer, TCG members Elizabeth Murchison, Max Stammnitz, Young Mi Kwon and Kevin Gori spent a few weeks in Tasmania performing Tasmanian devil field work. They joined devil trapping trips in the Channel Peninsula, where both DFTDs (DFT1 and DFT2) are present, and in the Freycinet Peninsula on Tasmania's East Coast. They saw many devils, both healthy and diseased, and shared scientific results and findings with collaborators.

Soheil Afshari, a student at the Department of Veterinary Medicine, Garmsar University, Iran, recently visited TCG from 9th July – 23rd July, 2018.
Soheil collected CTVT tumour biopsies from dogs in Iran. During his visit, Soheil extracted genomic DNA from these CTVT samples, performed PCR and genetic analysis to determine how CTVT in Iran differs from CTVT tumours collected from other countries. He also gave an presentation of his work at the end of his visit.

Well done Soheil, we wish you all the best for your PhD!

New research from TCG reveals that the canine transmissible venereal tumour (CTVT) first emerged from a dog that was closely related to an intriguing group of ancient North American dogs. 

The research, published in Science, reports that dogs arrived into North America together with people more than 10,000 years ago. By sequencing ancient DNA from dog bones collected from many sites across North America, we found that these dogs belong to a single genetic lineage that is related to modern-day Arctic breeds, such as huskies. Remarkably, however, these dogs appear to have largely disappeared since the arrival of Europeans 500 years ago.

One genetic legacy of these dogs does remain however: CTVT first arose from an animal that was related to these native American dogs. Thus, this worldwide cancer may be the closest remaining genetic vestige of a group of dogs that once roamed a continent.

Congratulations to Máire Ní Leathlobhair, co-first author on the study. The work was a large collaboration including scientists at the Universities of Cambridge, Oxford and Durham.

Our collaborator from South Africa, Mirjam van der Wel, gave a presentation "Canine transmissible venereal tumours" at the EASTERN CAPE VETERINARY CONGRESS on 4th of May 2018. It was well received by the audience and we are grateful that M. is spreading the knowledge of CTVT and our research amongst the clinical veterinary audience. Thank you for your enthusiasm, and congratulations, Mirjam! If you would also be interested to get involved in our research by collecting samples, see the following page for further info https://www.tcg.vet.cam.ac.uk/Research/get-involved-in-CTVT-research

WELL DONE Mirjam!!!

TCG member, Máire Ní Leathlobhair, recently returned from a field trip to Argentina. Máire's trip was funded by a Santander Mobility grant awarded by the University of Cambridge. In Argentina, she worked with vets and researchers based at the University of Buenos Aires (UBA) as well as the Catholic University of Córdoba (UCC), to collect samples and to study the prevalence of CTVT in Argentinian street dogs. We wish to say a huge thank you to Dr. María Verónica Brignone (UBA), Dr. César Koci, and Dr. Diego Graiff (UCC) as well as all of the fantastic veterinary hospital staff who helped with the sampling.

Many congratulations to Maximilian R. Stammnitz's new paper published on Cancer Cell, April 9, 2018!!

Mr. Juan Carlos Ramirez Ante from University of Caldas, Colombia, came to visit TCG for two weeks in January 2018. Juan is a Veterinarian and currently doing his Master degree at Professor Francisco Pedraza's group at University of Caldas.  Professor Pedraza and Juan are collaborators of our ongoing CTVT projects and had sent us hundreds of CTVT samples in the past few years. He spent two weeks with TCG members learning experimental methods for the analysis of Canine transmissible venereal tumour (CTVT), and investigated the journey of CTVT tissue samples from the biopsy to genomic DNA sequencing. We will also further develop a joint project on CTVT chemotherapy response.

Elizabeth Murchison has been elected as part of the 2017 intake of the EMBO Young Investigator Programme for young European researchers in life sciences.

Read the story about how a roadkill Tasmanian devil triggered Elizabeth Murchison's interest in transmissible cancers. The story, "Cancer in the wilderness", was published in Cell.

Four additional transmissible cancers have been discovered in marine bivalves - one of which appears to have jumped between species.

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.
