BLV/HTLV Genomics


We are developing and applying state-of-the-art genomic technologies to study the BLV-in-sheep model system in order to gain a detailed understanding of BLV and HTLV-1-induced leukemogenesis.  We have discovered a cluster of miRNAs in the BLV genome that has a major impact on disease progression by yet unknown mechanisms, and have shown that BLV/HTLV-1 proviral integration sites are not random and participate in early clonal expansion/persistence by perturbing neighbouring cancer drivers.
