Research Highlight


Investigation of a miRNA associated with cancer metastasis. Proj 2-Development of a novel nanoparticle for MPI analysis of thromboses

MicroRNAs (miRNAs) are a class of non-coding RNAs that were recently discovered and are becoming increasingly studied for their role cells. MiRNAs are used by the cell in conjunction with the RISC complex to post-transcriptionally control the expression of proteins. It has been demonstrated that miRNAs are differentially expressed in different tissues throughout the body and correlated with the pathology of cancer and other diseases. Using the differential expression of miRNA, diagnostic and therapeutic processes can be developed. A previous study analyzed the miRNA expression in BALB/c mice implanted with a 4T1 cell line. Candidate miRNAs were identified based on differential expression in metastatic sites versus the primary tumor. A miRNA was selected, based on the predicted mRNA targets, to be studied in vitro. Mimics of the miRNA will be used to study the effects of restoring expression of the miRNA in 4T1 and MDA-MB-231 cell lines. Understanding the miRNA’s mechanism will allow for the design of a diagnostic or therapeutic device to better treat metastatic cancers. Project 2: Carboxylmethyldextran-coated superparamagnetic iron oxide nanoparticles (SPIONs) can be viewed using magnetic particle imaging, which is an imaging method allowing for high resolution with high contrast. I am developing a protocol to attach fibrin-adherent peptides to the SPIONs. Fibrin is the principle protein constituent of clotted blood. The SPIONs are quickly pulled from circulation, leaving the SPIONs adhered to the blood clot. This method will be studied for future clinical use in identifying and imaging thromboses.

Trainee e-portfolios

While on co-op, trainees document their research in an e-portfolio.  This gives trainees the opportunity to provide regular updates on their research progress, reflect on training they are receiving, and explain how their research fits within the field of cancer nanomedicine.  These research e-portfolios can be accessed through individual trainee profiles.  The complete collection may be found here.

 


Presentation at CaNCURE Nanomedicine Day

At the completion of their co-op, trainees are provided with the opportunity to present their research to a wider audience.  For our June CaNCURE Nanomedicine Day, trainees prepare interactive, digital posters to display on electronic poster boards.  Over 100 faculty, students, and researchers attend this annual event!
