Postdoctoral Research Fellow, Bio-markers
The development of novel molecular tools for identification of circulating biomarkers has potential to improve early detection, intervention, and treatment of cancer. Circulating exosomes represent a valuable source of stable tissue/cellular-specific biomarkers. These membranous vesicles (40-100 nm diameter) actively released by normal and cancer cells, have been shown to establish long-distance communication by transporting proteins, metabolites, DNA, and RNA molecules (mRNAs, long non-coding RNA, and microRNAs). The laboratory has developed methods for purifying tissue-specific exosomes and established a next-generation sequencing protocols to evaluate the small-RNA of these extracellular vesicles. We have identified circulating prostate cancer biomarkers and are interested to develop novel methods to repackage exosomes and treat cancer cells both in vitro and in vivo. The successful candidate will refine our immunopurification assay to work with breast cancer cells and purify the content of their circulating exosomes. Using murine xenograft models the candidate will follow the process of metastasis to understand the contribution of exosomes and their contents to the formation of metastatic niches. Experience with general molecular biology, mouse models, next generation sequencing, as well as a high attention for detail will be essential assets. The candidate will also have the opportunity to develop molecular assays, work with state-of-the art technologies and equipment.
