Targeting the HTLV-I-Regulated BATF3/IRF4 Transcriptional Network in Adult T-Cell Leukemia/Lymphoma

After neonatal HTLV-I infection through breast feeding, approximately 5% of HTLV-I carriers eventually develop Adult T-Cell Leukemia/Lymphoma (ATLL) with a latency of ~50 years, suggesting that acquired genetic and epigenetic changes in cellular genes act in concert with HTLV-I to initiate and maintain oncogenic transformation. We and others have recently utilized next generation sequencing technology to identify mutated genes that could be pivotal in the pathogenesis of ATLL. However, due to the complexity of genomic/epigenetic alteration in the ATLL genome, the identification of indispensable genes for proliferation and/or survival of ATLL cells remains a formidable challenge.
