  • 2016 Terry Fox Run update: TFRI teams show immense support, with over $105,000 raised through team/t-shirt challenge

    by TFRI Editor | Sep 29, 2016
    TFRI-funded research teams from coast to coast showed their true colours this year, turning out by the dozens in researcher-designated purple T-shirts and forming teams to raise funds for cancer research at the 36th Terry Fox Run on Sunday Sept. 18. 

    Early estimates show the research community's fundraising efforts resulted in over $105,000 raised. The number is based on combining all the known TFRI teams totals that appeared online a few days after the run. In addition, approximately 500 T-shirts were purchased by teams, their friends, families and associates as part of the TFRI Purple T-Shirt Challenge. 

    Notably this year, the Vancouver Prostate Cancer Team raised over $37,000 in donations and purchased 58 purple T-shirts. The team turned out in full force at Stanley Park in Vancouver to run and hear the lead of the long-time program project grant, Dr. Martin Gleave, talk about how Terry Fox funds have had an impact on prostate cancer.(See team photo below).

    Showing another strong performance this year was the Ottawa-based COVCo PPG team led by Dr. John Bell, with approximately $22,000 raised.

    The teams from TFRI's Headquarters(HQ) in Vancouver and the COEUR,CPCBN and CRCHUM in Montreal were neck and neck with $6,300 and $6,625 raised. The HQ team also sold $1,145 in T-shirts in the days before the run and gained more support when members of several BC-based teams joined the HQ effort. 

    New and longstanding teams also showed strong turnouts and support. Drs. Singh, Lupien, Ohashi and Wrana, newly funded award holders, had teams in various locations in Toronto and Oakville run for the cause. TFRI researchers and trainees in Atlantic Canada also had a presence at runs in Halifax and St. John's. On the West coast, Drs. Humphries, Gleave, Lam and Ling headed teams.

    Notable standout individual fundraisers on teams this year were: Dr. Martin Gleave who raised over $20,000 for team VPC; Dr. Peter Black, also with VPC, who raised $11,000+; Dr. Rebecca Auer, with over $8,160 for the COVCo team; and TFRI HQ team member Marlene Manson, who raised over $2,300. 

    TFRI President and Scientific Director Dr. Victor Ling was thrilled by the strong turnout and expressed his thanks to each and every person who helped to make this year's team challenge and fundraising efforts so successful.  

     
    Although the final numbers raised this year through the annual national run are yet unknown, The Terry Fox Foundation said it is quite optimistic that this year will be as strong or better than the totals from last year.  "What we can see is that we are very happy with our online numbers which are on par with last year for donations received and increased in the number of participants who registered online," the Foundation told us. The Foundation expects to know and share more once the results of the school runs, held over the last two weeks, are tallied.  

     Below is a summary list of the TFRI teams that participated in the run and team challenge (according to online records):

  • Groundbreaking study finds miR-126 regulates distinct self-renewal outcomes in normal and malignant hematopoietic stem cells

    by TFRI Editor | Sep 29, 2016

    A groundbreaking new publication by Dr. John Dick’s TFRI-funded team has confirmed that miRNA expression patterns are predictive of disease outcome in leukemia, and play a powerful role in governing the fundamental properties that define the “stemness” state of human leukemia stem cells (LSCs).

    Published in Cancer Cell (February 2016), the present study generated a prognostic LSC-associated miRNA signature derived from functionally validated subpopulations of acute myeloid leukemia (AML) samples to investigate miRNA function in human AML stem cells. This was a unique idea in the literature. While over 2,500 validated human miRNA have been identified in our genome, there exists a lack of rigorous studies investigating the role of miRNA in either human hematopoietic stem cell (HSCs) or LSCs.

    Unlike other types of leukemia that have fairly high cure rates, AML’s prognosis is still very grim for certain subtypes. Since LSCs are an important reservoir of disease relapse in AML, understanding LSCs more completely at the molecular level in order to design improved and specific therapies to target these cells is critical for patient outcome.

    The study’s findings suggested that a small non-coding RNA, miR-126, is a highly expressed biomarker of both HSCs and LSCs. Further, despite the miRNA targeting the same proteins in these cells the functional outcome is opposite, whereby increasing the expression of miR-126 in HSCs and LSCs leads to the loss and increase in these cells respectively.

    Leukemia stem cells play central roles in disease progression and recurrence due to their intrinsic capacity for self-renewal and chemotherapy resistance. However, few regulators of human LSCs function are known. The present study established that miRNA played a powerful role in governing the fundamental properties that define the stemness state of human LSCs including quiescence, self-renewal, and chemotherapy response. Further, looking forward it may be possible to therapeutically target the networks that specifically control LSC through perturbation of miR-126 levels.

  • Montreal team discovers new molecular pathway key to understanding fat/cancer links

    by TFRI Editor | Sep 29, 2016

    fat tissue

    A new publication from the TFRI-funded team at McGill University (Goodman Cancer Centre) studying oncometabolism and molecular pathways
    is bringing new hope to the battle against obesity, cardiovascular disease and diabetes with the significant discovery of a new molecular pathway that has the ability to turn fat storage cells into fat burning cells.

    Published in Genes and Development (April 2016), the paper details how knocking out the tumour suppressor protein folliculin (FLCN) (which also helps regulate fat cells) in mice triggers a series of biomolecular signals that switch the cells from storing adipocytes to burning them.

    Obesity is a major health challenge around the globe, and is a major risk factor for metabolic disorders such as Type 2 diabetes, cardiovascular diseases and certain cancers. Scientists have long accepted the concept of white and brown fat cells: where white fat is deemed unhealthy and works as energy storage tissue while brown fat mainly burns energy to produce heat and keep body temperature constant. Beige fat has also been recently discovered, and functions somewhere in between white and brown fat. Conversion from white fat cells to beige or brown fat cells is a very desirable effect in obesity,and diabetic and metabolic syndrome indications, since excess energy in the body is not stored in fat tissue; it is burned in brown or beige fat tissue.

    The present study demonstrated that Flcn deletion in adipose tissue results in activation of an AMPK/PGC-1α/ERRα molecular axis, promoting mitochondrial biogenesis, oxygen consumption, FAO, UCP expression and heat production, thereby shifting white adipocytes from “lipid storage compartments” to active sites of lipid metabolism.

    Further, deletion of Flcn in mouse adipose tissues leads to a complete metabolic reprogramming of both white and brown adipocytes, leading the mice to exhibit significantly higher energy expenditure associated with an increase in mitochondrial respiration.

    In a nutshell, mice without Flcn stayed slim and burned more fat as energy as the fat storage units turned into fat burning engines through the stimulation of beige and brown fat pathways. The discovery of the folliculin pathway lays the groundwork for new medications to be developed that will stimulate the ‘browning’ process, potentially reducing the risk of obesity, cardiovascular disease, and diabetes.

  • Dual expression study helps identify B-cell lymphoma patients at high risk for CNS relapse

    by TFRI Editor | Sep 29, 2016

    non-Hodgkin's lymphoma cells

    Despite improvements in outcome in diffuse large B-cell lymphoma (DLBCL) in the monoclonal antibody rituximab treatment era, central nervous system (CNS) relapse continues to occur and typically is incurable. Identifying high-risk patients is essential to focus on effective prophylaxis strategies.  To date, there have not been any identified robust biomarkers to predict those at high risk.  Previous seminal studies from the BC Cancer Agency have identified MYC and BCL2 dual expression to be associated with poor outcome.  Importantly, a study published in Blood (May 2016) by a TFRI-funded team suggests that dual expression of MYC and BCL2 tested by immunohistochemistry (IHC) is associated with an increased risk of CNS relapse.  

    DLBCL is the most common type of non-Hodgkin lymphoma (NHL), comprising around 30 to 40 % of all cases. Initial chemotherapy treatments are often successful in more than half of patients, but many patients still relapse. Dual translocation of MYC and BCL2, also known as “double-hit lymphoma,” has been associated with a high risk of central nervous system (CNS) relapse, yet the impact of dual expression of MYC and BCL2 (dual expressers) on the risk of CNS relapse remains unknown.

    In the present study, 428 patient biopsies from newly diagnosed DLBCL treated with curative-intent rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) were collated from existing tissue microarrays and were evaluated for MYC and BCL2 dual protein expression by IHC. The cumulative risk of CNS relapse was higher in dual expressors and defined a high-risk group with the non-GCB/ABC DLBCL subtype (~16% vs ~3%, P=.01).  Further, MYCBL2 dual expression remained a significant variable in multivariate analyses, in addition to the recently described CNS risk model (CNS-IPI (international prognostic index) where those patients with a high CNS-IPI risk score and dual expression of MYC and BCL2 had a CNS relapse risk of ~23%. 

    These results have immediate and direct clinical implications, as patients in this category can be screened with CNS-directed staging studies and strongly considered for CNS prophylaxis strategies.  Further studies are ongoing to define additional biomarkers and genetic factors that can help refine the identification of a high-risk CNS relapse group to focus aggressive CNS-directed staging procedures and select patients for prophylactic strategies.

  • Ovarian cancer: Mapping the clonal spread

    by TFRI Editor | Sep 29, 2016

    Dr. Shah
    Dr. Sohrab Shah

    A team of B.C.-based, TFRI-funded scientists are breaking new ground with a recent study that tracked the clonal spread and 
    intraperitoneal mixing of high-grade serous ovarian cancer (HGSOvCa), the deadliest subtype of the disease.

    Their findings, published in Nature Genetics (July 2016), mapped the different patterns of metastatic spread in the peritoneal cavity of women with HGSOvCa. At least two divergent modes of intraperitoneal metastasis were identified, highlighting the interplay between genomically diverse clones and their migratory potential prior to treatments in this subtype of ovarian cancer.

     As many as 80% of  (HGSOvCa) patients suffer relapse after initial response to treatment. It is characterized by widespread and early intraperitoneal spread to organs, and the patients account for nearly 70% of all ovarian cancer cases.

    The present study provided valuable information about the composition of the cancer cell groups in metastatic cancers. It was found that many different types of cancer cells make up a patient’s tumour, which may explain why some cells are eradicated by treatment while others become resistant, eventually resulting in the patient's relapse. HGSOvCa also appears to have the unique ability to metastasize prolifically throughout the abdomen, which often results in patient death.

    These findings suggest that some cancer cells may have had pre-existing properties of resistance before a patient begins treatment. Understanding this could lead to women being given a more aggressive, multi-treatment approach at the beginning of their therapy in an effort to prevent patient relapse, versus waiting until the cancer has already returned. Future research will help to define cell migration maps in more patients, with a focus on ascertaining which cells are resistant to treatment, and enabling researchers to create predictive tools to better inform future care for women with this lethal type of ovarian cancer.

  • New class of small molecules enhances OV replication

    by TFRI Editor | Sep 29, 2016

    An innovative paper by Dr. Jean-Simon Diallo  (TFRI-funded Canadian Oncolytic Virus Consortium (COVCo) and collaborators Drs. Jeffrey Smith and Christopher Boddy was published in Scientific Reports (May 2016).  They discovered and developed a class of new small molecule compounds that selectively enhance oncolytic viruses (OV) in cancer tissue, making them more likely to destroy tumour cells and eradicate the disease.

    The use of engineered viral strains such as gene therapy vectors and oncolytic viruses to selectively destroy cancer cells is poised to make a major impact in the clinic and to revolutionize cancer therapies. Yet in clinical studies, OV therapy has shown highly variable rates of patient response. The heterogeneous nature of tumours is widely accepted to be a major obstacle for OV therapeutics and highlights a need for strategies to improve the efficacy of viral replication.

    The present study looked at the development of a new class of small molecules for selectively enhancing OV replication in cancer tissue. Medicinal chemistry studies led to the identification of compounds that enhance multiple OVs and gene therapy vectors. The lead compounds increase OV growth by up to 2,000-fold in vitro and demonstrate remarkable selectivity for cancer cells over normal tissue ex vivo and in vivo.  These small molecules also demonstrate enhanced stability with reduced electrophilicity and are well-tolerated in animals. This pharmacoviral approach expands the scope of OVs to include resistant tumours, further potentiating this transformative therapy.

    The process of selecting promising molecule compounds may be like looking for a needle in a haystack, but the present study’s results were very promising. Nearly 30,000 molecules were screened initially to find just over a dozen highly active ones.  From there, the team selected a lead candidate that they used as a model to create nearly 100 more molecules closely related to that initial lead compound, from which a handful of compounds that hold promise for human applications were identified --  including one they are very excited about based on promising animal studies. 

    In summary, the current study has developed new molecular tools in the search for a cure for cancer, as well as identified credible drug candidates for evaluation in OV clinical trials. In addition, these new molecular tools provide an opportunity to better understand how cells protect themselves from viral infection. The applications of this span beyond cancer but are also relevant for treating hereditary diseases using gene therapy, and also to the development and manufacturing of vaccines.

  • Ultrasound, imaging effective tools to monitor treatment response

    by TFRI Editor | Sep 29, 2016

    Terry Fox-funded researchers have made a critical finding in monitoring breast cancer patient response to chemotherapy treatment: patient response to treatment can be detected in as little as one week by using optics and ultrasound respectively instead of waiting the traditional four to six months. Their findings were published in Oncotarget (March 2016).

    Breast cancer is the second-leading cancer related death in women, and there are more than 17 different tumour subtypes. About 10 to 15 % of tumours fall under the category of locally advanced breast cancer (LABC), defined as Stage 3 to 4  tumours that are greater than five centimetres in size, and potentially involving one or more lymph nodes. Further, survival outcomes for LABC are poor: Only 25% of women may achieve complete pathological response and up to 46% of patients may develop recurrence within five years.

    The present study evaluated pathological response to neoadjuvant chemotherapy using quantitative ultrasound (QUS) and diffuse optical spectroscopy imaging (DOSI) biomarkers of LABC in 22 different patients at weeks 0, 1, 4, 8, and post-operatively. Cell death detection was done using quantitative ultrasound and spectroscopic methods the team developed, while the optical work tracked changes in hemoglobin and blood flow.

    The results were promising: QUS and DOSI demonstrated potential as coincident markers for treatment response and may potentially facilitate response-guided therapies. Multivariate QUS and DOSI parameters were shown to increase the sensitivity and specificity of classifying LABC patients as early as one week after the start of treatment.

    The present publication is the first in-human study showing that QUS and DOSI work effectively both alone and together, and could be used as low-cost tools to personalize a patient’s chemotherapy treatment. The potential impact in the clinic is huge: a patient would no longer be required to undergo four to six months of treatment that isn’t going to work. Instead, treatment success can be very quickly assessed and changed to a different type of chemotherapy if necessary.

     Six stellar TFRI research teams will use $27.3 million to engineer precision medicine across a range of cancers

    FOR RELEASE 1PM EST

    Wednesday, Sept 7, 2016

     

    Attention Editors:

    > The Terry Fox Run is being held on Sunday, Sept. 18th
    The brain cancer project will focus on new treatments for glioblastoma (The Tragically Hip’s Gord Downie announced in May he has this cancer)

    Vancouver, BC – Six outstanding Canadian research teams will use $27.3 million in new funding to engineer precision medicines for patients whose cancer has relapsed or for whom current treatments are ineffective or non-existent.

    The Terry Fox Research Institute teams are conducting research into brain, colorectal, prostate, breast and ovarian cancers and lymphoma at research centres and hospitals across the country. Some studies will include undertaking trials for immunotherapy -- using the body’s immune system to kill cancer cells.

    The majority of the funding ($26.1 million) is being provided by The Terry Fox Foundation through funds raised annually from the Terry Fox Run. National funding partner, The Canadian Institutes of Health Research, is contributing $1.2 million to co-invest in the project with the goal of finding more effective treatment for a hard-to-treat breast cancer called triple negative breast cancer.

    “We thank the Terry Fox Foundation and the Canadian Institutes of Health Research for making these investments possible.  Our shared goal is to provide cancer patients with the right remedy for the right cancer at the right time – so precision medicine will help us to find more cures for cancer.  The projects being funded today are judged by international experts as being excellent, leading-edge and having the best potential for us to achieve this goal,” says Dr. Victor Ling, TFRI president and scientific director.

    “We are delighted to see our supporter funds invested across such a range of cancers since Terry Fox believed in funding all types of cancer research. We hope Canadians will continue to show their support for Terry’s cause and cancer research on Sunday, September 18 by participating in and donating to a Terry Fox Run in their community,” said Terry Fox Foundation executive director Britt Andersen. The Terry Fox Run will be held on Sunday, September 18.

    The Terry Fox New Frontiers Program Project Grants (PPGs) and Translational Research Programs are highly competitive. Following international peer review, funds are awarded annually to teams of investigators to support breakthrough and transformative biomedical research which may form the basis for innovative cancer prevention, diagnosis and/or treatment. See below the investment breakdown by project and province:

  • “Smart” nanoparticle (PEARLs) a promising gem to target and treat tumours with greater precision

    by User Not Found | Jul 14, 2016

    Dr. Zheng
    Dr. Gang Zheng

    TORONTO,
    Canada – July, 14, 2016 – Dr. Gang Zheng and a team of biomedical researchers have discovered a “smart” organic, biodegradable nanoparticle that uses heat and light in a controlled manner to potentially target and ablate tumours with greater precision.

    The proof-of-concept findings, published online today and designated a “very important paper” in the leading chemistry journal Angewandte Chemie, provide a viable approach to boosting the clinical utility of photo-thermal therapy in treating cancer, says Dr. Zheng, senior scientist at the Princess Margaret Cancer Centre and professor of medical biophysics at the University of Toronto. Dr. Zheng also holds the Joey and Toby Tanenbaum/Brazilian Ball Chair in Prostate Cancer Research. He talks about and demonstrates the research at https://youtu.be/EEN6Mz5iWBI.

    In the lab, using phantom models, the “smart” nanoparticle the team has dubbed  PEARLs – photo-thermal enhancing auto-regulating liposomes – showed how it can solve the two bottlenecks currently preventing more effective use of photo-thermal therapy with patients. These are overheating of tissue that can cause collateral damage during treatment, and the inability to ablate larger tumour volumes because the light stops travelling when it is absorbed.

    Explains the chemist: “Our smart nanoparticle is super cool. It can absorb light, generate heat and ablate the tumour. It’s a thermal sensor and once it reaches the desired ablation temperature of 55C, it becomes invisible, allowing the light to move deeper into more areas of the tumour and repeat the treatment process.

    “The result is a promising new way to heat and ablate larger volumes of the tumour with minimal damage to surrounding tissues in a controlled and precise way. The next step is to conduct pre-clinical studies to test the concept further.”

    For the past 10 years at PMCC, Dr. Zheng’s research has focused on advancing nanoparticle technology by harnessing light, heat and sound to advance tumour imaging and targeted treatment.
