Description
Mitochondrial DNA (mtDNA) encodes essential components of the respiratory chain and loss of mtDNA leads to mitochondrial dysfunction and neurodegeneration. Mitochondrial transcription factor A (TFAM) is an essential component of mtDNA replication and a regulator of mitochondrial copy number in cells. Studies have shown that TFAM knockdown leads to mitochondrial dysfunction and respiratory chain deficiencies. ATP synthase is Complex V of the mitochondrial respiratory chain. It is driven by a proton gradient between the intermembrane space and the mitochondrial matrix and generates the majority of cellular ATP. The knockdown of coupling factor 6 (Cf6), one of the components of the proton channel F0, causes dysfunction in the complex, leading to mitochondrial dysfunction and respiratory chain deficiencies. Using gene expression analysis, we aimed to investigate the effects of mtDNA dysfunction in the CNS at the molecular level.

Description
Chronic high sugar feeding induces obesity, hyperglycemia, and insulin resistance in flies and mammals. To gain insight into the mechanisms underlying this response, we profiled gene expression in chronically high sugar fed, wandering (post-prandial) third instar wild type larvae (L3). These data were compared to control-fed larvae as well as those (mid-L3) actively feeding for twelve hours on both diets.

Description
We generated single and double knockouts of AtNHX5 and AtNHX6 in order to invesigate possible functions in Arabidopsis. nhx5/nhx6 exhibited severe growth retardation related to cell size and proliferation, as well as endosomal trafficking perutrbations. The results implicate endosomal NHX antiporters in novel cellular functions. In order to investigate further the possible functions of AtNHX5 and AtNHX6, we compared the transcrptional profiles of single and double AtNHX5 and AtNHX6 knockouts. We looked for changes in gene expression might help us to elucidate the molecular events associated with the apparent requirement of AtNHX5 and AtNHX6 for normal growth and development.

Description
The exposure to and contamination by Persistent Organic Pollutants (POPs), which include pesticides used worldwide and polyaromatic hydrocarbons, is detrimental to human health and diverse ecosystems. Although most mechanistic studies have focused on single compounds, living organisms are exposed to multiple environmental xenobiotics, simultaneously, throughout their lives. The experimental evidence useful for assessing the effects of exposure to pollutant mixtures is scarce. We investigated the effects of exposure to a combination of two POPs, which employ different xenosensors, on global gene expression in a human hepatocyte cell model, HepaRG.
Publication Title
Two persistent organic pollutants which act through different xenosensors (alpha-endosulfan and 2,3,7,8 tetrachlorodibenzo-p-dioxin) interact in a mixture and downregulate multiple genes involved in human hepatocyte lipid and glucose metabolism.

Description
GGF2 is a recombinant human neuregulin-1 in development for chronic heart failure. Phase 1 clinical trials of GGF2 were put on hold when transient elevations in serum aminotransferases and total bilirubin were observed in 2 of 43 subjects receiving GGF2. However, aminotransferase elevations were modest and not typical of liver injury sufficient to result in elevated serum bilirubin. Several translational approaches were used to understand the liver response associated with GGF2.
