Project description:Diazotrophs provide the main source of reactive nitrogen to the ocean, sustaining primary productivity and CO2 uptake. Climate change is raising temperatures, decreasing pH and reducing nutrient availability. How microbes respond to these changes is largely unexplained. Similarly, the role of DOM in the growth and survival of certain diazotrophic organisms is poorly understood. Moreover, growing evidence indicates some diazotrophs are capable of utilizing distinct DOM compounds via osmotrophy providing them with additional metabolic plasticity and ecological advantages compared to other non-diazotrophic microbes. We aimed to understand how osmotrophy could modify carbon uptake and alleviate energy stress in diazotrophs under ongoing climate change perturbations. We hypothesized that Crocosphaera preferentially uses DOM when labile as a carbon source in present pH conditions, as compared to future more acidic scenarios with higher access to inorganic carbon. Alternatively, the lower pH may cause Crocosphaera to be energy limited when trying to maintain intracellular homeostasis which would favour DOM uptake as an extra source of energy.

Project description:The pressure changes in hepatic microenvironment may be involved in the regulation of proliferation and invasion of hepatocellular carcinoma, but the mechanism is unknown. This project simulates the mechanical microenvironmental conditions of liver cirrhosis, exerts the static water pressure on human hepatoma cell lines and observes the changes of proliferation and invasion of hepatoma cells under different pressure loading conditions. Then screens the differential expression mechanic-responsive miRNAs under the optimal loading condition and carry out biological verification. Bioinformatics analysis was used to explore the related pathways. This study provides a theoretical basis for the prevention and treatment of liver cancer and provides a direction for finding effective drugs for clinical treatment of liver cancer.

Project description:Series containes 4 independent experiments and high and low power scanns for each independent experiment. Genome-wide mRNA expression profiles of Saccharomyces cerevisiae growing under hydrostatic pressure were characterized. We selected a hydrostatic pressure of 30 MPa at 25°C because yeast cells were able to grow under these conditions, while cell size and complexity were increased after decompression. Functional characterization of pressure-induced genes suggests that genes involved in protein metabolism and membrane metabolism were induced. The response to 30 MPa was significantly different from that observed under lethal conditions because protein degradation was not activated under 30 MPa pressure. Strongly induced genes included those that contribute to membrane metabolism and which are also induced by detergents, oils, and membrane stabilizers. Keywords: repeat sample
