Research Bio

The main goals of Dr. Ricke's laboratory are to find ways to cure or prevent clinically relevant urological abnormalities including prostate cancer, benign prostatic hyperplasia, and bladder outlet obstruction. To accomplish these goals a better understanding of the molecular mechanisms underlying these conditions must be achieved. Elucidation of the pathways involved in these diseases will provide insight for determining the appropriate therapeutic compound for preclinical and ultimately clinical testing.

Most organs consist of 2 main tissue layers comprised of various cell types: epithelial cells (functional cells) and stromal cells (supporting cells). In diseases such as prostate cancer, epithelial cells develop into cancer, whereas stromal cells are seemingly unaffected. Hence the biomedical community has focused primarily on epithelial cells to better understand pathways involved in carcinogenesis. Consequently, little is known about the role of stroma in disease progression or how epithelial cells and stromal cells communicate with one another during the manifestation of disease. Understanding how these two tissue layers interact during disease progression may hold the key to understanding the processes involved in lower urinary tract abnormalities and to therapies aimed to prevent or cure them.

In most solid cancers epithelial cells grow uncontrollably, ultimately leading to metastasis and mortality. Until recently the role of stromal cells has been thought to play a passive role in cancer progression. However recent research has demonstrated that stromal cells play a necessary role in cancer progression. This suggests that stromal cells may be an important therapeutic target. Since stromal tissues are genetically stable, relative to cancerous epithelial cells, therapies directed toward the stroma may be more effective and longer lasting. Through our research, we have effectively discovered new and essential mechanisms involved in disease progression and our preclinical studies have demonstrated that we can effectively prevent the disease progression. Future studies will evaluate the role of these therapies in a clinical setting.

The Ricke lab is currently working in 4 areas of research.
1. The role of sex hormones and the tumor-microenvironment in prostate cancer progression
2. Evaluation of environmental factors in prostate cancer progression, benign prostatic hyperplasia, and bladder outlet obstruction
3. Identification of biomarkers for aggressive vs. indolent prostate cancer
4. The role of dietary and environmental factors in the development and prevention of diseases in the lower urogenital tract
