Of which, the efficacy of dispersant as a mitigation strategy and its toxic effects on aquatic fauna remains controversial. To enhance our understanding of potential sub-lethal effects of exposure to chemically dispersed-oil, sub-adult red drum (Sciaenops ocellatus) were continuously exposed to a Corexit 9500: DWH crude oil chemically enhanced water accommodated fraction (CEWAF) for 3-days and transcriptomic responses were assessed in the liver. Differential expressed gene (DEG) analysis demonstrated that 63 genes were significantly impacted in the CEWAF exposed fish. Of these, 37 were upregulated and 26 downregulated. The upregulated genes were primarily involved in metabolism and oxidative stress, whereas several immune genes were downregulated. Quantitative real-time RT-PCR further confirmed upregulation of cytochrome P450 and glutathione S-transferase, along with downregulation of fucolectin 2 and chemokine C-C motif ligand 20. Ingenuity Pathway Analysis (IPA) predicted 120 pathways significantly altered in the CEWAF exposed red drum. The aryl hydrocarbon receptor pathway was significantly activated, while pathways associated with immune and cellular homeostasis were primarily suppressed. The results of this study indicate that CEWAF exposure significantly affects gene expression and alters signaling of biological pathways important in detoxification, immunity, and normal cellular physiology, which can have potential consequences on organismal fitness.}, journal={Ecotoxicology and Environmental Safety}, author={Sherwood, T.A. and Rodgers, M.L. and Tarnecki, A.M. and Wetzel, D.L.}, year={2021} }

We wanted to understand which specific genes are differentially expressed in liver and gill tissues directly after oiled sediment exposure and with the addition of a recovery period. Furthermore, we wanted to examine specific enriched pathways in these two tissues to determine the impact of exposure with and without a recovery period on biological processes (e.g. immune function). Liver and gill tissues were chosen because they represent two distinct organs that are highly important to consider when examining the impacts of oiled sediment exposure. The liver is the classic detoxification organ, while the gill is in direct contact with sediment in benthic fishes. Examination of these two tissues, therefore, generates a broad understanding of the transcriptomic consequences of oil exposure across an organism. Gene expression for interleukin 8 (il8) and interleukin 1B (il1β) was significantly increased versus control measurements for fish exposed to oiled sediments for 35 days in gill tissue. Hierarchical clustering of gene expression showed that tissue type was the main driver of gene expression (rather than treatment). The inclusion of a 30-day post-exposure recovery period showed a return of il8 and il1β gene expression in the gill to baseline expression levels. However, the recovery period increased the number of differentially expressed genes and significantly affected canonical pathways in both tissue types. Pathways related to cholesterol biosynthesis were significantly suppressed in oil-exposed flounder with a recovery period, but not in the exposed flounder without a recovery period. At the end of the exposure, 17 pathways were significantly affected in the gill, including thyroid hormone metabolism-related pathways, which were the most influenced. Liver tissue from the recovered fish had the greatest number of enriched pathways for any tissue or time point (187). Cellular and humoral immune response pathways were considerably impacted in the liver after the recovery period, suggesting that the immune system was attempting to respond to potential damage caused from the chronic oil exposure. Our results demonstrate that liver and gill tissues from southern flounder were differentially altered by Deepwater Horizon oiled sediment exposure and that a 30-day recovery period after exposure substantially shifted gene expression and canonical pathway profiles.}, journal={Aquatic Toxicology}, author={Rodgers, M.L. and Sherwood, T.A. and Tarnecki, A.M. and Griffitt, R.J. and Wetzel, D.L.}, year={2021} }

Many studies have identified the toxicological effects of PAHs in estuarine and marine fishes, however, only recently has work begun to identify the combinatorial effect of PAHs and abiotic environmental factors such as hypoxia, salinity, and temperature. This study aims to characterize the combined effects of abiotic stressors and PAH exposure on the cardiac transcriptomes of developing Fundulus grandis larvae. In this study, F. grandis larvae were exposed to varying environmental conditions (dissolved oxygen (DO) 2, 6 ppm; temperature 20, 30 °C; and salinity 3, 30 ppt) as well as to a single concentration of high energy water accommodated fraction (HEWAF) (∑PAHs 15 ppb). Whole larvae were sampled for RNA and transcriptional changes were quantified using RNA-Seq followed by qPCR for a set of target genes. Analysis revealed that exposure to oil and abiotic stressors impacts signaling pathways associated with cardiovascular function. Specifically, combined exposures appear to reduce development of the systemic vasculature as well as strongly impact the cardiac musculature through cardiomyocyte proliferation resulting in inhibited cardiac function and modulated blood pressure maintenance. Results of this study provide a holistic view of impacts of PAHs and common environmental stressors on the cardiac system in early life stage estuarine species. To our knowledge, this study is one of the first to simultaneously manipulate oil exposure with abiotic factors (DO, salinity, temperature) and the first to analyze cardiac transcriptional responses under these co-exposures.}, journal={Science of the Total Environment}, author={Allmon, E. and Serafin, J. and Chen, S. and Rodgers, M.L. and Griffitt, R. and Bosker, T. and Guise, S. and Sepúlveda, M.S.}, year={2021} }

There still exists a dearth of information on the neurotoxicity and endocrine disrupting effects of these contaminants, especially for marine and estuarine species. Here, we assessed the neuroendocrine effects of HHCB and AHTN using adult clams, Ruditapes philippinarum, and yolk-sac larvae of sheepshead minnow, Cyprinodon variegatus. The clams were treated with concentrations (0.005–50 μg/L) of each compound for 21 days. Meanwhile, sheepshead minnow larvae were exposed to 0.5, 5 and 50 μg/L of HHCB and AHTN for 3 days. Enzyme activities related to neurotoxicity (acetylcholinesterase - AChE), neuroendocrine function (cyclooxygenase - COX), and energy reserves (total lipids - TL) were assessed in R. philippinarum. Gene expression levels of cyp19 and vtg1 were measured in C. variegatus using qPCR. Our results indicated induction of AChE and COX in the clams exposed to HHCB while AHTN exposure significantly inhibited AChE and COX. Gene expression of cyp19 and vtg1 in yolk-sac C. variegatus larvae exposed to 50 μg/L AHTN was significantly downregulated versus the control. The results of this study demonstrate that HHCB and AHTN might pose neurotoxic and endocrine disrupting effects in coastal ecosystems.}, journal={Environmental Research}, author={Ehiguese, Friday Ojie and Rodgers, Maria L. and Araújo, Cristiano V.M. and Griffitt, Robert J. and Martin-Diaz, M.

Oil released from the 2010 Deepwater Horizon spill reached habitats where estuarine fish routinely spawn. In addition, estuaries are highly dynamic environments, therefore, fish in these areas are routinely exposed to varying salinity and dissolved oxygen (DO) levels, each of which are known to modulate transcriptional responses. Fish exposed to oil often display altered immune competence, and several studies have shown that Deepwater Horizon oil in particular causes modulation of various immune functions. However, few studies have directly examined how environmental parameters may affect oil-induced immunomodulation, particularly in early life stage fishes when the immune system is still developing. To this end, we examined transcriptional patterns of immune genes and pathways in Fundulus grandis larvae to various oil (0, 15 μg/L), salinity (3, 30 ppt), and DO (2.5, 6 mg/L) regimes in a fully factorial design. Our results suggest that immune pathways are generally activated in all treatment groups with the exception of the Low Salinity/No Oil/Hypoxia treatment where immune pathways are largely suppressed, and the High Salinity/No Oil/Hypoxia treatment where pathways are unchanged. The High Salinity/Oil/Hypoxia treatment had the largest number of enriched immune pathways (44 as defined by IPA and 43 as defined by ConsensusPathDB), indicating that oil under certain environmental conditions has the potential to further modulate immune-related genes, pathways, and responses in fish.}, journal={Comparative Biochemistry and Physiology - Part D: Genomics and Proteomics}, author={Rodgers, M.L. and Serafin, J. and Sepúlveda, M.S. and Griffitt, R.J.}, year={2021} }
