A mouse well travelled

It was recently brought to our attention that a mouse model generated by Ozgene has become very useful in the area of cancer research. This particular model has been used to study melanomas, lung cancer, ovarian tumorigenesis, ductal hyperplasia and adenocarcinoma on two continents.

The Pik3ca (lat-1047R) mouse, originally developed by Ozgene for Dr Wayne Phillips and recently utilized by Dr Martin McMahon, has been used in a range of cancer research that has led to five scientific publications so far.

Dr Phillips is the head of the Surgical Oncology Research (Phillips) Laboratory at the Peter MacCallum Cancer Centre in Australia. His main focus and interest of study is on the role of the phosphoinositide 3-kinase (PI3K) signalling pathway in cancer. The novel mouse model created for his research has proved useful not only for himself, but for others around the world studying cancer, particularly Dr McMahon.

“The Pik3ca(lat-1047R) mouse, generated by Ozgene for Dr. Wayne Phillips, is turning out to be a very useful addition to our tools for studying PI3′-kinase signaling alone and in concert with other pathways. In my opinion, it is superior to the more conventional transgenic mice used for similar purposes.”

-Dr Martin McMahon

Dr McMahon is the Director of Professional Education and Co-Leader of the Developmental Therapeutics Program at the UCSF Helen Diller Family Comprehensive Cancer Center. The novel Pik3ca mouse model was utilized by Dr McMahon in his research on the role of RAS-regulated signal transduction pathways in the aberrant behaviour of melanoma, thyroid, pancreas and lung cancer.
