| Summary: | T-cell acute lymphoblastic leukaemia (T-ALL) is an aggressive neoplastic malignancy characterised by the accumulation of multiple oncogenic and epigenetic alterations in haematopoietic T-cell precursors leading to their uncontrolled proliferation and accumulation in the bone marrow. For many years it has been established that the occurrence of activating mutations, alterations in transcription factors expression, impairment in cell cycle regulators, and hyperactivation of NOTCH1 signalling play prominent roles in the pathogenesis of this disease. Recently, the introduction of high-resolution screening and next-generation sequencing platforms revealed that T-cell progenitors accumulate additional mutations, affecting protein kinase signalling, protein translation, and epigenetic control mechanisms, providing novel attractive targets for therapy. While the contributions of direct genomic events are well understood as causative agents of hyperactive kinase signalling pathways, the epigenetic rewiring of kinase signalling cascades via DNA methylation, histone post-translational modifications, and non-coding miRNAs remains less well explored. In this review, we provide novel perspectives on epigenetic regulatory aspects of kinase signalling heterogeneity in T-ALL pathogenesis and therapeutic outcomes. |
