Emil Lou Lab

Welcome to the Emil Lou Lab at the University of Minnesota Medical School. Our main research interest involves investigating tumor heterogeneity and intercellular communication in a spectrum of invasive and aggressive solid tumor malignancies. Projects in our lab focus on investigating the biology of cancer cells as they relate to cancer cell invasion, progression, tumor recurrence, and chemotherapy resistance. We invite you to learn more about our work and our research team.

Research Philosophy

I am a physician-scientist with a strong interest and a translational approach to investigation of solid tumor malignancies at the cellular and molecular level. As a fellowship-trained and board-certified medical oncologist and neuro-oncologist, I have a strong interest in a ‘bedside-to-bench-and-back’ approach to translational oncology and laboratory research. At the national level, I have served on the American Society of Clinical Oncology (ASCO) Scientific Committee for GI Cancers (2012-15), and more recently on the ASCO Scientific Committee for Developmental Therapeutics Tumor Biology Track (2022-25; Track Leader 2023-24). I also serve on the Education Committee for the North American Neuroendocrine Tumor Society (NANETS)(Co-Chair 2023-24, Chair 2024-25), and as Deputy Editor of the Cell Press journal Molecular Therapy-Oncolytics. From 2019-2023, I served as Medical Director of the University of Minnesota Masonic Cancer Center's Clinical Trials Office-Solid Tumor Unit. 
Over the past several decade, my lab has been funded by the American Cancer Society, the American Association for Cancer Research, the Minnesota Ovarian Cancer Alliance, the Randy Shaver Cancer Research and Community Fund, and many generous donors who have strongly supported my team's research mission. Identifying pertinent clinical problems in oncology that can be investigated in the laboratory setting is a high priority for my basic scientific and translational research program.

Intercellular Communication in Cancer

The Lou lab primarily focuses its work on studying intercellular communication via cellular extensions called tunneling nanotubes (TnTs, or TNTs, for short). These structures are long, thin, spontaneously forming actin-based cellular extensions that occur in a variety of cell types including inflammatory cells (e.g. B cells, macrophages), neurons, and more recently being examined in malignant cells. When examined in vitro, TnTs are differentiated from other actin-based structures such as filopodia, invadopodia, and lamellopodia by their characteristic non-adherence to the substratum. Furthermore, once they attach to nearby or distant cells in culture, they form direct connections that serve as conduits for intercellular transport of a variety of cellular cargo and contents, including but not limited to lipophilic vesicles, Golgi vesicles, and even mitochondria. To date, there have been relatively few studies of TnTs in cancer, particularly in primary cancer cells or tumors. Much remains unknown about these structures, including their in vivo relevance. Our team was the first to demonstrate, using confocal microscopy, presence of nanotubes in intact malignant tumors. For confocal and other microscopy videos of this work, click here.

Ongoing projects on TnTs in our lab include the following:

  • Investigation of the underlying function of TnTs and relevance to invasive cancers. We are actively investigating whether TnTs serve as a selective and unique conduit for cellular cargo that drive vital cellular processes, including carcinogenesis and metastasis.
  • Investigation of the mechanisms of TnT formation and maintenance in cancer.
  • Identifying differences in TnT formation in malignant vs. precursor or stromal cells, and identification of cellular biomarkers that contribute to selectivity of TnT formation.

Translational Research Program

Novel biomarkers of chemoresistance in ovarian cancer:

An additional project in our lab involves a biomarker-based clinical trial in collaboration with the UMN Gynecologic Oncology group, with the purpose of identifying novel biomarkers of chemoresistant ovarian cancers. We enrolled patients and collected tumor specimens at the time of debulking surgery, as well as serum samples at the time of diagnosis and longitudinally throughout their care, with the purpose of correlating potential biomarkers that may predict which patients harbor tumors most susceptible to developing resistance to platinum-based chemotherapy, a major obstacle to treatment of these patients. We isolated circulating tumor cells (CTCs) to and correlated these findings to platinum-resistance as well. Results to date have been published in peer-reviewed journals, including in JAMA Oncology in 2019, when we reported a correlation between Tumor-Stroma Proportion and Platinum Chemotherapy Resistance in Ovarian Cancer. This work was sponsored by the KL2 Scholars Career Development Program, Clinical and Translational Science Institute, University of Minnesota.
