Trending with Impact: Alternative RNA Splicing in Pancreatic Cancer



September 16, 2021

Oncotarget published this trending research perspective on March 16, 2021, entitled, "Pancreatic cancer driver mutations are targetable through distant alternative RNA splicing dependencies" by researchers from the Medical Scientist Training Program, The Johns Hopkins University School of Medicine, Baltimore, MD; Departments of Molecular and Systems Biology, Surgery, and Medicine, Dartmouth Geisel School of Medicine and Norris Cotton Cancer Center, Lebanon, NH; Department of Therapeutic Radiology, Yale University, New Haven, CT; Department of Molecular Biophysics and Biochemistry, Yale University, New Haven, CT; Department of Pathology, Stony Brook University Renaissance School of Medicine, Stony Brook, NY. Abstract: Pancreatic ductal adenocarcinoma (PDAC), the most common histological subtype of pancreatic cancer, has one of the highest case fatality rates of all known solid malignancies. Over the past decade, several landmark studies have established mutations in KRAS and TP53 as the predominant drivers of PDAC pathogenesis and therapeutic resistance, though treatment options for PDACs and other tumors with these mutations remain extremely limited. Hampered by late tumor discovery and diagnosis, clinicians are often faced with using aggressive and non-specific chemotherapies to treat advanced disease. Clinically meaningful responses to targeted therapy are often limited to the minority of patients with susceptible PDACs, and immunotherapies have routinely encountered roadblocks in effective activation of tumor-infiltrating immune cells. Alternative RNA splicing (ARS) has recently gained traction in the PDAC literature as a field from which we may better understand and treat complex mechanisms of PDAC initiation, progression, and therapeutic resistance. Here, we review PDAC pathogenesis as it relates to fundamental ARS biology, with an extension to implications for PDAC patient clinical management.
