Areas of Research & Specialization
I have two main areas of interest: (1) a pediatric cardiomyopathy called Barth Syndrome and (2) pancreatic cancer. In summary, I employ lipidomics and molecular pharmacology for an elucidation of disease mechanisms.
Barth Syndrome: In cardiomyopathy research, I investigate the molecular pathology of Barth Syndrome (BTHS). BTHS is a rare but fatal, X-linked dilated cardiomyopathy and skeletal myopathy arising due to mutations in the tafazzin gene, the protein product of which is a mitochondrial enzyme of the same name. My work has demonstrated that tafazzin is a transacylase responsible for remodeling the mitochondrial inner membrane phospholipid cardiolipin (CL). We also showed that mutated tafazzin caused myopathic mitochondrial aberrations. Specifically mutated tafazzin containing mitochondria had alterations in lipid profile and evinced cristae membrane collapse involving degenerate supramolecular protein assembly. There were also discrepancies in protein distribution of complex V (ATP synthase) and tafazzin in the mitochondrial supramolecular complexes and therefore perhaps delinquent cristae membrane packing. That this was relevant in the context of cardiocytes was demonstrated when we showed that tafazzin mutations affected mitochondrial development during cardiocyte differentiation. Further, in lymphoblasts obtained from BTHS patients, delinquent CL remodeling was accompanied with mitochondrial accrual of monolysocardiolpin (MLCL), the monodeacylated form of CL. Importantly, we provided evidence that MLCL accumulation could be reversed employing small molecule regulators of calcium independent phospholipase A2, suggesting that in addition to deficient membrane packaging, MLCL amassment was a crucial intracellular lesion in this syndrome. In my current work at the Pacific University School of Pharmacy, I am interested in the development and validation of putative translational therapeutics for Barth Syndrome (BTHS). I will explore the following two broad areas: (1) the role of acute and chronic inflammation in cardiomyopathy and (2) the regulation of mitochondrial calcium in BTHS. For these, I will employ molecular biology, lipidomics and proteomics tools.
Pancreatic Cancer: A recent area of research interest is investigation into the development and progression of pancreatic cancer. Although rarer than other forms of cancer, pancreatic carcinoma has a poor prognosis since it is usually discovered late. Of the many types of pancreatic neoplasia, I am interested in understanding the mechanistic development of pancreatic ductal dysplasia. In particular my emphasis is on the identification of natural compounds that cause apoptosis in pancreatic cancer cell lines. At the Pacific University School of Pharmacy, I aim to explore alterations in intracellular signal transduction pathways downstream of treating cells with natural compounds such as Diindolylmethane (DIM), Neem leaf extracts and other pharmacognostic agents. These exploratory studies will serve to provide preliminary data for translational therapeutic discovery.
