- Research Interest Statement: RNA processing misregulation has been highlighted as a critical driver of tumorigenesis through emerging discoveries in the past decade. Alternative splicing (AS) and nonsense-mediated mRNA decay (NMD) are two important RNA processing mechanisms in controlling gene expression, and their misregulation often leads to malignancy. Although therapeutic approaches to modulate AS/NMD in several genetic diseases are reaching the clinic, this is an under-explored area in cancer. My research is focused on bridging the gap between RNA biology and cancer research. My work distinguishes itself by the systematic use of diseaserelevant model systems to elucidate the mechanisms of RNA processing defects in cancer. Recent efforts to profile AS/NMD in human tumors have revealed that many of the changes in AS/NMD are cell-typespecific. Therefore, studies investigating the underlying mechanisms in disease-relevant model systems will provide invaluable insights into the role of RNA biology in cancer, elucidate pathological phenomena, and aid in developing novel therapeutic strategies. My recent works (Rahman et al., Genes Dev 2020; Rahman et al., Cell 2020; Yoshimi et al., Nature 2019) identified a critical link between AS-coupled-NMD (ASNMD) and hematologic malignancies. My current research explores the molecular basis of aberrant regulation in targeted AS-NMD genes in myelodysplastic syndromes and leukemia and the development of targeted tools (such as antisense therapy) to modulate aberrant AS-NMD as a therapeutic approach. I am also interested in exploring the role of AS-NMD in the pathogenesis of different solid tumors, including melanoma and breast tumors. My research will broaden the basic understanding of AS and NMD regulation in the post-transcriptional RNA processing pathway in normal physiology and aberrant regulation in cancer. In addition, identifying oncogenic targets should lead to the discovery of novel cancer biomarkers and aid in developing targeted cancer therapies.
