Research Interests

 

As part of the Mary Hendrix research team we have recently embarked on the classification and molecular profiling of tumors, especially cutaneous and ocular melanomas, based on differential gene expression (microarray analysis). Our findings based on the molecular signature of aggressive melanoma cells indicate the expression of multiple phenotypes, which appears to mimic a multi-potent, embryonic-like phenotype. One example of this tumor cell plasticity was seen in the ability of aggressive melanoma cells (but not poorly aggressive cells) to express endothelial cell-specific markers and participate in vasculogenic mimicry. The aggressive tumor cells also demonstrated the ability of deposit “molecular cues” into the basement membrane matrix of their environment that can subsequently induce poorly aggressive cells to participate in vasculogenic mimicry and express endothelial cell-specific markers. The observation that aggressive tumor cells can express multiple molecular phenotypes should lead to the development of new diagnostic markers and therapeutic targets for clinical intervention of cancer.
