September 2017 – More POPs in the news


Our latest study, published in the journal Environmental Health Perspectives, examined persistent organic pollutant levels (POPs) in yellowfin tuna from around the world’s oceans. The results indicate that the pollutant load depends on the location of catch, varying in level by as much as 36 times between sites. We also found that overall pollutant levels are positively linked to the presence of a small subset of pollutants, termed Transporter Interfering Chemicals or TICs. This new class of chemicals may be involved in enhancing bioaccumulation of chemicals in organisms by inhibiting cellular defense proteins. This research lays the groundwork for future studies to examine natural and anthropogenic sources of these chemicals, and to examine how pollutant distribution and bioaccumulation patterns change over time, particularly under rapidly changing climate conditions.

July 2017 – Update on Recent Publications


Four new lab publications are available: Dr. Sascha Nicklisch’s studies on mercury and pollutant levels in yellowfin tuna (Environ Pollution 2017; Environ Health Perspect 2017), Dr. Gökirmak’s work on alternative splicing in the sea urchin MRP gene ABCC1 (Am J Phys Cell 2016), and collaborators’ Ramakrishnan and Patel characterization of ADP-ribosyl cyclases in early sea urchin development (Messenger 2016).

May 2017 – Welcome to Dr. Catherine Schrankel


This month we welcomed the newest member of our lab, Dr. Catherine Schrankel, all the way from Toronto, Canada. She will be studying the regulation of ABC transporters during embryogenesis, and how this impacts the future detoxification capabilities of adult tissues and cell types.
