Project Details
MicroRNAs (miRs) are short evolutionary conserved non-coding RNAs that regulate gene expression. They are expressed in all tissue types and are found in all body fluids including serum. It has been demonstrated that expression levels of certain miRs are altered in the setting of cancer e.g. chronic lymphocytic leukemia, ovarian cancer, diffuse large B cell lymphoma. These alterations are detectable not just in the cancerous tissue, but also in the patient’s serum. This offers a non-invasive method of obtaining relevant samples for molecular analysis and disease monitoring.
We have developed a methodology for screening miRs present in serum/plasma using Nanostring technology. This method is now being applied to the analysis of samples collected from patients with Acute Myeloid Leukaemia, Myelofibrosis, Hodgkin's Lymphoma, Myelodysplasia and Glioma/Glioblastoma.
