Description
Plants respond to environmental stresses by altering transcription of genes involved in the response. The chromatin modifier ATX1 influences gene expression and factors that modulate ATX1 activity would affect indirectly the expression of ATX1-regulated genes. Here, we demonstrate that dehydration is such a factor indicating that ATX1 is involved in the plants response to drought. In addition, we show that a hitherto unknown Arabidopsis gene, At3g10550, encodes MYO1, a phosphoinositide 3-phosphatase related to the animal myotubularins. By a functional genomics approach, we show that ATX1 and MYO1 participate in overlapping drought-response pathways. The shared set of genes, representing the ultimate targets of an ATX1-MYO1 signaling mechanism responding to drought, provided insights into the relationship of the epigenetic factor and the lipid phosphatase from the other end of the response pathway.

Description
The clinical presentation, course and treatment of methamphetamine-associated psychosis (MAP) are similar to that observed in schizophrenia (SCZ) and subsequently MAP has been hypothesized as a pharmacological and environmental model of SCZ. However, several challenges currently exist in accurately diagnosing MAP at the molecular and neurocognitive level before the MAP model can contribute to the discovery of SCZ biomarkers. We directly assessed subcortical brain structural volumes and clinical parameters of MAP within the framework of an integrative genome-wide RNA-Seq blood transcriptome analysis of subjects diagnosed with MAP (N=10), METH-dependency without psychosis (MA) (N=10) and healthy controls (N=10). We used RNA-Sequencing gene expression to characterize molecular signatures associated to METH and MAP status compared to healthy control subjects. Overall design: Peripheral blood luekocytes gene expression was subject to transcriptional analysis for 10 MAP subjects, 10 subjects with METH-dependency without psychotic symptomics and 10 healthy controls.
