Determining how proteins interact with breast cancer cells

posted by:

Hello, everyone! My name is Sami Khan and I’m an MSc candidate in the Department of Anatomy and Cell Biology at Western University. In Dr. Alison Allan’s laboratory at the London Regional Cancer Program, we study proteins that may be involved in the preferential metastasis (or spread) of breast cancer to the lung and the potential of these proteins to be used as targets for novel breast cancer therapies.

Sami Khan - Pamela Greenaway-Kohlmeier Translational Breast Cancer Research Unit (TBCRU) scholarship recipienI am specifically interested in a family of proteins called selectins, which are normally found in the lung. Together with fellow lab members, we have demonstrated that the selectins enhance the migration or movement of breast cancer cells towards the lung. We are now in the process of determining the mechanism by which selectins interact with breast cancer cells and exert their function. Learning this will better enable us to develop strategies that can limit the spread of breast cancer cells to the lung and ultimately limit lung metastasis. These translatable findings could then be used clinically to improve breast cancer patient outcomes.

Without the funding support from the Breast Cancer Society of Canada, our research would not have been possible. As I finish up my MSc thesis, I am thankful for all the opportunities I was afforded and strongly believe that continued support from BCSC and its generous donors to researchers and trainees will lead to a breakthrough in breast cancer therapy one day soon.

Investigating early events in estrogen signaling

posted by:

Hi, my name is Bart Kolendowski and I am a PhD candidate in the Department of Biochemistry at Western University. I currently work at the London Regional Cancer Program in Dr. Joe Torchia’s lab researching the role of the estrogen receptor in breast cancer.

The estrogen receptor is often a therapeutic target in a subset of breast cancers. My work has focused on investigating early events in estrogen signaling to better understand how therapies work and, more importantly, why they sometimes fail.

Bart-Kolendowski - BCSC - Pamela Greenaway-Kohlmeier Translational Breast Cancer Research Unit (TBCRU) scholarship recipientDuring my tenure as a Pamela Greenaway-Kohlmeier Translational Breast Cancer Research Unit (TBCRU) scholarship recipient, I have discovered previously unknown mechanisms that drive estrogen-dependent breast cancer. Importantly, these discoveries have led to the identification of new targets that may prove to be of therapeutic value for patients suffering from breast cancer.

I have been invited to present this work at the Canadian Institutes of Health Research National Student Research Competition held at the University of Winnipeg as well as the prestigious Keystone Symposia on Nuclear Receptors held in Snowbird, Utah.

Earlier this year, we submitted a manuscript based on my findings to a high-impact academic journal for publication. I am happy to announce that we are currently in the process of completing revisions and anticipate that the work will be published in the upcoming months!

None of this would have been possible without the continued support of the TBCRU and the Breast Cancer Society of Canada.

Thank you!

What being a breast cancer researcher has taught me.

posted by:

Hello! My name is Ashkan Sadri and I’m a Masters candidate in Dr. Alison Allan’s lab in the Department of Anatomy and Cell Biology at Western University, just coming to the conclusion of my thesis research.

When I engage in casual conversation, the topic of graduate school and breast cancer research often arise. By far, the most common question I’m asked is: “Does a cure exist?” And to that, it’s hard to give a simple answer.

Ashkan Sadri, BCSC ResearcherWhat is difficult to communicate to those outside of the cancer research field is that, due to the complexity of cancer, it is unlikely a single cure exists. Over the past two years, the basis of my research has been to investigate whether the factors produced by different organs in the body such as bones and the lungs can promote a rare, stem-like population of breast cancer cells with heightened capacity to form metastatic tumors in these organs. Our research findings turned out to challenge our predictions, providing an important means for thinking outside of the box. Not only were the stem-like traits of breast cancer cells not promoted when exposed to the lung microenvironment, they were actually reduced. We have gone on to identify a novel subpopulation of breast cancer cells that may potentially be involved in metastasis to the lung, using pathways that are distinct from the original cancer stem cell model. Thus, when asked, about a “cure to cancer”, it’s important to consider the complex nature of cancer biology and the many unknowns that exist, emphasizing the need for valuable research to be conducted.

When confronted with a treatment, breast cancer cells often find alternative means to progress along their path. Cancer treatments are effective in blocking key pathways, but alternative routes exist that the cancer cells can utilize. This is why supporting breast cancer research is vital. Learning about different mechanisms that drive tumour development are necessary to finally get breast cancer under control. By supporting breast cancer research, researchers are able to make a global impact when it comes to gaining ground on cancer.

Thank you to BCSC for your trainee support!

Finding cancer: Improving x-ray detector technology for earlier detection of breast cancer

posted by:

Hello! I’m Tomi Nano, a PhD candidate in the department of Medical Biophysics at Western University. I work at Robarts Research Institute in Dr. Ian Cunningham’s lab on development of new x-ray detector designs and measurements of their performance.

Tomi Nano, a PhD candidate in the department of Medical Biophysics at Western UniversityThe Pamela Greenaway- Kohlmeier Translational Breast Cancer Unit (TBCRU) Traineeship Program has supported my research in improving detector technology performance for earlier detection of breast cancer. Women who enrol in mammography screenings have up to 40% reduced risk of death from breast cancer, but since mammograms require exposure to radiation, detectors should produce high-quality images with the least amount of radiation so as to minimize the risk to patients. The aim of my research project is to develop an “ideal” x-ray detector which produces the highest-quality images with little radiation.

Improvements in image signal-to-noise ratio (SNR) are known to improve breast cancer detection. During my traineeship, our lab has developed a detector design that produces images with higher SNR of small features and fine detail which are important for early detection of breast cancer. Better visualization of fine detail in mammograms should help radiologists more accurately identify cancer. To further understand the clinical process of breast cancer screening, I have begun an observership at St. Joseph’s Hospital with Dr. Anat Kornecki. Our goal is to apply our new technological advancements to address the needs clinicians have for detecting breast cancer earlier.Tomi Nano

The support from TBCRU enabled me to share my discoveries with other scientists and clinicians at the 2017 Mammography Workshop and Imaging Winter School conference organized by the Canadian Organization of Medical Physicists (COMP). In addition to discussing my translational breast cancer research with physicists, radiologists and technologists, this meeting provided an opportunity to establish future collaboration with leading Canadian scientists, such as Martin Yaffe from Sunnybrook Hospital in Toronto and Jean Seely from the Department of Diagnostic Imaging at Ottawa Hospital.

Thank you TBCRU and BCSC for supporting translational breast cancer research!

Breast cancer cell migration research

posted by:

Hello, everyone! My name is Sami Khan and I’m an MSc candidate in the Department of Anatomy and Cell Biology at Western University. I work at London Cancer Regional Program under the supervision of Dr. Alison Allan. Our lab focuses on breast cancer metastasis: the process by which cancerous cells can leave the breast and establish tumours in other organs.

Sami Khan BCSC funded Breast Cancer ResearcherOne of the most common and deadly sites of breast cancer metastasis is the lung. For my project, I am currently investigating a family of proteins produced by the normal lung called selectins, and how they may play a role in helping breast cancer cells spread to and grow in the lung as metastatic tumours. To date, we have promising results that suggest selectins are involved in the migration (movement) of breast cancer cells and we are now investigating the mechanism by which this happens. Successful identification of a common mechanism by which the different selectins act will provide a new potential therapeutic target in limiting the spread of breast cancer to and from the lung.

This April, I had the opportunity to present my research at the 108th Annual Meeting of the American Association of Cancer Research in Washington, D.C. With over 20,000 attendees at the conference, it was an amazing opportunity to interact with scientists and clinicians from around the world, and learn about the breadth of research being conducted in the field. Returning to the lab with my newfound knowledge and expert advice, I am excited to see what we can accomplish next in our goal towards curing breast cancer.

Thank you to BCSC for your trainee support!

Novel Molecular Imaging Technologies

posted by:

Hello! My name is Katie Parkins and I am a PhD candidate in the Department of Medical Biophysics at Western University. I work in the Imaging Research Laboratories at Robarts Research Institute under the co-supervision of Drs. Paula Foster and John Ronald.

Katie Parkins, PhD CandidateMy research involves using novel molecular imaging technologies to study concomitant tumour resistance (CTR): the ability of the primary tumour to inhibit the growth of secondary metastases. Tumor cell dormancy and recurrence are important clinical problems for breast cancer patients and their physicians as secondary metastases can develop many years after successful removal of the primary tumour and adjuvant therapy. We expect this research will produce important information about what influences metastatic tumour growth and possibly advance therapeutic development for breast cancer patients.

I have been fortunate to have many opportunities presenting my work at both international and regional conferences. My first author manuscript was published in the Nature Publishing Group journal, Scientific Reports, and recently recognized at the 2017 London Health Research Day as a recipient of the Lucille and Norton Wolf Publication Award. It’s very encouraging to see the interest in my work and the excitement for new results to come!

Thank you to BCSC for your trainee support!

Developing a molecular imaging technique using MRI

posted by:

Hello, My name is Yonathan Araya, I am a PhD candidate in the Department of Medical Biophysics at Western University. I work in the Imaging Research Laboratories at Robarts Research Institute under the supervision Dr. Timothy Scholl.

Yonathan Araya Breast Cancer ResearcherDr. Scholl’s lab focuses on developing advanced magnetic resonance imaging (MRI) techniques for use with novel molecular imaging probes of cancers. These molecular imaging probes are important tools to help oncologists map enzymes, proteins and amino acids, which are difficult to detect using conventional MRI methods and are linked to different cancers. The new methods (collectively known as molecular imaging) would help to assess solid tumours and measure their response to treatment.

The focus of my project has been developing a molecular imaging technique using MRI for the detection of specific proteins and cell-based interactions in breast cancers. I exploit the specific magnetic field dependence of tissues and contrast agents using our fast field-cycling magnet (which we call ‘dreMR’) to assess the metabolism and inflammatory response of solid breast cancer tumours. Last year, I described in our findings that there was a weak magnetic field dependence of tissues at clinical magnetic field strengths and that we can exploit this information to characterize cancerous tissues. The work was submitted to a scientific journal.

Currently, our lab is interested in measuring the up-regulation of serum albumin and the increased inflammatory response associated with the poor prognosis breast cancers and quantifying the changes in response to therapeutic treatment. This work is ongoing at the University Hospital and Robarts Research Institute.

Thank you for your trainee support!

MRI cell tracking for breast cancer

posted by:

Hi, My name is Ashley Makela and I am a PhD candidate in the department of Medical Biophysics at Western University. I am working at Robarts Research Institute in Dr. Paula Foster’s lab where our main focus is to develop magnetic resonance imaging (MRI) techniques to “track” cells.

Ashley Makela - Breast Cancer ResearcherMy research involves using this MRI cell tracking specifically in breast cancer. Doing so, we can image specific cells called tumour associated macrophages (TAMs) and with this, we can get both information about the primary tumour and also visualize where the cancer spreads within the body (metastasis). We believe these cells are important to learn more about; their presence helps the tumour grow, allows the cancer to metastasize and they are associated with a poor prognosis in the majority of breast cancer cases. This research may produce important information about the influence of TAMs on tumour growth and metastatic spread and give insight on how to use this information to aid in detection, prognosis and treatment evaluation.

I’ve recently published my first research article and I’m looking forward to presenting my findings in Honolulu this April at the International Society for Magnetic Resonance in Medicine.

Thank you to BCSC for your trainee support.

Receptor for Hyaluronan-Mediated Motility or RHAMM

posted by:

Hi everyone!

My name is Alexandra Hauser-Kawaguchi and I’m a PhD candidate in the Department of Chemistry at Western University. I work in Dr. Len Luyt’s lab at London Health Sciences Centre’s London Regional Cancer Program.

Alexandra Hauser-Kawaguchi - BCSC Breast Cancer ResearcherFor the past few years, I have been studying the protein RHAMM (Receptor for Hyaluronan-Mediated Motility). RHAMM levels increase in response to fragmentation of the compound hyaluronan (HA), which ultimately results in the spread of cancer and thus poorer outcomes for breast cancer patients.

We have recently been developing stapled peptides as RHAMM mimics. “Stapled” peptides are compounds that have been partially cyclized, giving them the appearance of having a “stapled” backbone. This “stapling” allows the peptide to circulate through the body longer than it would otherwise. This is ideal, as our RHAMM mimics are part of a drug discovery initiative, in which we have shown that they are able to block inflammation associated with breast cancer relating to fragmented HA. The RHAMM mimics could also help stop the disease from spreading to other parts of the body.

In September of 2016, I had the opportunity to attend the 34th European Peptide Symposium and 8th International Peptide Symposium in Leipzig, Germany. I was one of eight chosen to give an oral presentation in front of 700 scientists. This experience was frightening but also thrilling, and the high point of my graduate student career to date. After meeting with and learning from experts in the field, I returned to the lab full of new ideas on how to make our compounds better drugs for treating breast cancer.
