The Methodist Hospital Investigation Institute was awarded an $11.five million Center Grant by the National Institutes for Wellness (NIH) to study the very best way to attack deadly cancer stem cells to enhance treatments for breast cancer. Other members of the team consist of Baylor College of Medicine along with the University of Texas Well being Science Center at Houston.

“Targeting cancer stem cells, rather than cancer cells, is actually a completely new strategy for treating cancer,” stated Dr. Stephen Wong, director of the Center for Bioengineering and Informatics in the Methodist Hospital Analysis Institute and principal investigator for the grant study. “By attacking the cancer stem cell, we hope to eliminate cancer’s ability to grow, recur or metastasize.”

The NIH grant will enable Wong’s team to model breast cancer stem cells – or see what they appear like and how they act – employing advanced genetic, imaging and computational modeling techniques. Wong stated as soon as the cells are modeled within the lab and in real environments, the team will probably be in a position to predict the behavior of cancer stem cells, enabling them to test drugs that might kill the cells or prevent the cells from duplicating and metastasizing.

Cancer stem cells, also called tumor initiating cells, have the ability to resist drugs, become cancer cells, and split into a cancer cell and another stem cell. Traditional cancer treatments use chemotherapy to kill cancer cells, but are not optimized to kill the stem cell.

“Targeting the cancer stem cell is the new horizon for cancer analysis,” Wong stated. “We have put together a really strong team of top experts inside the field. We’re in a position to combine that talent using the technologies at our disposal at Methodist, Baylor, and UT. This can be a formidable combination that has potential to achieve real breakthroughs in cancer research. It’s great to now have the backing of the NIH to help us move ahead.”

Wong’s team will build a modeling platform for investigation of breast cancer, with special emphasis on the role of tumor-initiating cells (TIC), or cancer stem cells. This platform will consist of two closely related components: biological experiments and mathematical computational modeling.

“Further, our systems biology approach will allow us to evaluate responses to experimental therapies that might restrain or kill tumor initiating cells in a manner not possible before,” Wong said.

The biological component will use new experimental imaging methods to identify, localize, purify and characterize the cancer stem cells. Tumor initiating cells cannot be noticed making use of traditional imaging techniques. Methodist has invested in high resolution microcopy that can see at nanometer, rather than millimeter resolution, including a confocal laser scanning microscope, a Coherent anti-Stokes Raman Scattering (CARS) microscope, and an in vivo multi-photon laser scanning microscope. Further protocols will probably be designed to comprehend the stem cell’s ability to metastasize, including spatial localization and movement, and distinct changes in gene expression and cellular signaling of breast cancer stem cells.

For the mathematical modeling component, the team will develop bioinformatics and bio-imaging models to integrate and analyze the data generated from biological experiments. They are going to use the information obtained from information analysis and biological knowledge to build computer-based models to mimic the cells’ behavior and drug remedy response.

Besides providing a basic framework for understanding breast cancer stem cell evolution, the models will allow us to predict how the natural process of cancer development will play out in various circumstances, Wong stated. The ultimate aim is better, a lot more effective treatment for eliminating breast cancer in our patients.
