SELECTBIO Conferences Circulating Nucleic Acids and Circulating Rare Cells: Liquid Biopsy for Early Cancer Detection

Lucia Languino's Biography

Lucia Languino, Professor of Cancer Biology, Thomas Jefferson University

Dr. Languino investigates the role of cell adhesion receptors in phenotypic changes of prostate cancer cells. A strong research focus is being devoted to the study of the cross-talk between cell adhesion molecules, extracellular matrix proteins and growth factor receptors in vitro and in vivo systems and how this cross-talk affects intracellular signal transduction, cell survival, cell migration and cell division. Dr. Languino's research interests also focus on the cellular and molecular characterization of the metastatic process of prostate cancer with particular emphasis on the signals directing distant localization of prostate cancer cells

Cancer Extracellular Vesicles (EVs) found in blood are heterogeneous and show unique protein compositions. Our analysis shows that a prostate cancer EV subset, designated exosomes, carries a unique repertoire of integrins, which are surface receptors for extracellular matrix.  Using iodixanol gradients, immunoblotting and size measurements we show that integrins are differentially expressed in cancer exosomes. Our recent studies demonstrate that exosomes from prostate cancer cells contribute to horizontal propagation of unique integrin-associated invasive phenotypes.  We also show that exosomal integrins are transferred to cells in the tumor microenvironment and mediate response to therapy. This presentation will discuss the role of exosomal integrins in cancer progression and therapy response, and their potential use as clinical biomarkers for non-invasive diagnosis of cancer.
