A lack of baseline heath indices for offshore Gulf of Mexico (GoM) teleosts complicated impact assessments of the Deepwater Horizon (DWH) oil spill. While measurement of contaminant levels in fish after a pollution event can document exposure, such data fail to provide meaningful information about how this contact affects an animal's physiology. Controlled exposure studies have highlighted the utility of biomarkers that may indicate deleterious, long-lasting effects of pollutant exposure on various life stages of fish, however, their extrapolation to wild-caught, non-model species is challenging. In an increasingly chemically-saturated environment, it can also be difficult to separate the influence of …

Therapeutic Modulation Of Cancer Metabolism With Dichloroacetate And Metformin, Nathan Patrick Ward

The robust glycolytic metabolism of glioblastoma multiforme (GBM) has proven them susceptible to increases in oxidative metabolism induced by the pyruvate mimetic dichloroacetate (DCA). Recent reports demonstrate that the anti-diabetic drug metformin enhances the damaging oxidative stress associated with DCA treatment in cancer cells. We sought to elucidate the role of metformin’s reported activity as a mitochondrial complex I inhibitor in the enhancement of DCA cytotoxicity in the VM-M3 model of GBM. We demonstrated that metformin potentiated DCA-induced superoxide production and that this was required for enhanced cytotoxicity towards VM-M3 cells with the combination. Similarly, rotenone enhanced oxidative stress resultant …

Obesity is a current epidemic in the United States. Greater than one third of adults and nearly one fifth of children are classified as obese (Ogden, 2014). Increased awareness of this problem has triggered interest into the potentially causal agents in our environment. These agents, termed obesogens, are a type of teratogen hypothesized to work during embryonic development by programming offspring to store excess fat. A type of teratogen, obesogens are also typically reprotoxic, affecting germline development and embryonic viability. These noxious teratogens span a variety of different chemical classes including estrogen mimics, metals and metalloids, biocides, and even voluntary …
