Tasmanian devils, those adorable marsupial scavengers, are facing a dire threat: a contagious cancer that has decimated their population. But there's a glimmer of hope on the horizon, thanks to a groundbreaking research partnership. The Colossal Foundation and the University of Tasmania are joining forces to develop a vaccine and explore gene editing, offering a beacon of light in the fight against devil facial tumour disease (DFTD).
A Cancerous Catastrophe
DFTD is a double-edged sword, with two distinct cancers at play. DFT1 emerged in 1996 and has spread across most of Tasmania, while DFT2 made its debut in 2014 in the state's south and continues to spread its deadly influence. This disease spreads through bites during feeding and mating, leading to tumours around the mouth and face, ultimately causing starvation and death. The impact is devastating, with approximately 80% of wild devils lost since its discovery.
A Two-Pronged Attack
The research partnership is tackling the problem head-on with two innovative approaches.
Vaccine Development
One strategy involves creating an oral bait vaccine designed to train the devil's immune system to combat both cancers. This vaccine, developed by Andrew Flies and his team at the Menzies Institute for Medical Research, offers a promising solution. The Colossal Foundation's involvement is crucial, as they provide the resources to establish a colony of fat-tailed dunnarts, a mouse-sized marsupial relative of the devil, in Hobart. This colony will serve as a crucial testing ground for vaccine safety before trials on devils commence.
Flies acknowledges the challenges of working with an endangered species and the lack of marsupial research tools, but the partnership with Colossal Foundation accelerates progress. The vaccine's potential to protect wild devils without trapping and injecting each individual is a significant advancement.
Gene Editing: A Precision Strike
The other approach delves into the realm of gene editing, targeting a gene called LZTR1. Researchers believe this gene plays a pivotal role in the origin of the tumours. By editing this gene, they aim to reduce the susceptibility of devils to the cancers. This strategy showcases the power of genetic manipulation in combating disease.
A Race Against Time
The race is on to save the Tasmanian devil, a keystone species in the ecosystem. The decline of devils has far-reaching consequences, including the spread of feral cats. The partnership between the Colossal Foundation and the University of Tasmania exemplifies the power of collaboration in scientific research. While the vaccine still needs to pass safety trials, the potential for a brighter future for these iconic marsupials is within reach.
In my opinion, this research partnership is a beacon of hope, showcasing the power of innovation and collaboration in the face of a devastating environmental crisis. The future of the Tasmanian devil may hinge on these groundbreaking efforts.
