The Canadian Breast Cancer Foundation – BC/Yukon Region (CBCF) is thrilled to announce a game-changing discovery in triple-negative breast cancer (TNBC). This breakthrough points to one of the first personalized therapies for the treatment of TNBC and reports that RSK inhibition has the potential to block TNBC recurrence.
The breakthrough research of Canadian Breast Cancer Foundation – BC/Yukon Region’s (CBCF) Doctoral Breast Cancer Research Fellows Kristen Reipas and Dr. Anna Stratford will today be published in the highly recognized medical journal, Stem Cells.
Supported by University of British Columbia (UBC) Associate Professor in the Faculty of Medicine, Dr. Sandra Dunn, trainees Ms. Reipas and Dr. Stratford have identified a protein critical to the survival of triple-negative breast cancer (TNBC) patients. This breakthrough research has the potential to cure TNBC by targeting a protein called RSK2, which eliminates TNBC cells completely. The study, published June 5, 2012 in Stem Cells medical journal, reports that RSK2 inhibitors have the ability to kill all of the cells including cancer stem cells which give rise to cancer recurrence. This cutting-edge discovery will potentially personalize the treatment of TNBC on an international scale.
"RSK2 inhibition provides a novel therapeutic avenue for TNBC and holds the promise of being one of the first targeted therapies for this challenging form of breast cancer," says Dr. Sandra Dunn, UBC.
TNBC is diagnosed in approximately 400,000 women worldwide and is considered the most difficult breast cancer subtype to treat due to lack of effective therapies. Dr. Dunn’s laboratory at the Child & Family Research Institute at BC Children’s Hospital led the project in collaboration with scientists from Breakthrough Breast Cancer UK and the University of Aukland NZ.
This project began four years ago when UBC Post Doctorate Fellow Dr. Stratford of the Child & Family Research Institute was awarded $214,000 by CBCF BC/Yukon to support her research on this project entitled “The regulation of the Y-box binding protein-1 (YB-1) by p90 ribosomal S6 kinase (RSK) in triple-negative breast cancer.”
In addition, a doctoral candidate in the Experimental Medicine Program at UBC, Kristen Reipas was awarded $35,000 in support of this research study, entitled “Targeting Y-box binding protein-1 eliminates tumor-initiating cells and reduces relapse in triple-negative breast cancer.”
The BC/Yukon Region of CBCF is proud to award the Breast Cancer Research Postgraduate Fellowships every year to the most qualified breast cancer research projects across the province. These awards are intended for qualified health care professionals, MD graduates or recent PhD graduates to provide assistance in launching a career as independent, social, clinical or basic science investigator in breast cancer research.
Canadian Breast Cancer Foundation – BC/Yukon Region
The BC/Yukon Region of CBCF was established in 1992 to make a difference in breast cancer research and breast health for the BC population. Every year CBCF, along with its donors, sponsors and partners, raises funds to support unique and innovative initiatives in prevention, early detection, treatment, research and emerging issues in the health care workforce.

That is fantastic news! Do they have any idea when it will be available to the public?
I am one year and four months past diagnoses and knowing something like that was available if necessary is a great stress reliever.
Thank you for your wonderful blog!
Sherry: There is a lot of research right now on various targeted therapies, and clinical trials will certainly be available should you need them. Let's plan on you not needing them, though. Treatments have to work their way through the FDA (in the US), so it can take a while. Phase 3 clinical trials are a good option, though, and those should be a possibility. Still, let's plan on a full recovery for you. Pat
Pat I can't thank you enough for your beautiful, passionate and amazing work here. You're a true angel.
My mom was diagnosed with stage III c triple negative in april, 2011 and I started to do all the research to make sure she would get the better treatment. Your blog was something that kept me warm and with my faith on the cure, oposed to all the terrible things going on on the general web.
She did neoadjuvant AC (4 rounds), 8 taxol, followed by a mastectomy and intense radiotherapy. She had almost complete pathological response (they have different methods to measure that, in one she had complete, in another one she had "almost complete"), and after the mastectomy and radio she's been without evidence of disease for about a year now.
Since she was a IIIc patient, I'll always fear a recurrence, so I keep researching. I want to be ready if something happens. Your blog helped me A LOT, not only because you post this amazing good news about new treatments, but specially because you really care about women like my mom, you're like a safe bay in this messed up sea.
Thank you for your work, you're an amazing person.
All our loving goes out to you, from São Paulo- Brazil.
