Dr. Ashton studies RNA alternate splicing (AS), a cellular process for changing genomic instructions into functional proteins. AS plays an important role in the regulation of gene expression, protein diversity and ultimately, in species evolution. Indeed, it’s changes in AS, not the size of the genome, that have driven the evolution and biological distinctiveness of homo sapiens.
He seeks to understand the mechanisms of action for AS as they relate to cardiac disorders and cancer and to develop diagnostic tests that could determine clinical outcomes such as disease onset and progression. In particular, he focuses on cardiac disorders that occur during pregnancy, such as pre-eclampsia (a high-risk condition characterized by high blood pressure and renal failure) that can lead to heart problems in women later in life. Currently there are no diagnostic tests or treatments for pre-eclampsia, other than traditional therapies for high blood pressure.
Dr. Ashton uncovered a protein generated by AS in the placenta, and his research has shown it’s the primary driver of pre-eclampsia. By understanding and targeting this AS pathway, he and his team hope to uncover novel diagnostics and therapeutics that will translate into significant advances in obstetric care.
His oncology research is focused on the ways in which AS impacts breast cancer and melanoma.
