Project description:Rat mammary glands were obtained from individual rats in RXR treated (a) and control (b) conditions (12 rats in each condition). The 24 samples were hybridized individually. Also, in each condition, samples were combined into different pools of 2, pools of 3, pools of 12. Technical replicates were also run. Keywords: other
Project description:This study aimed to investigate the effects and underlying mechanisms of sarsasapogenin (SAR) on dietary methionine choline deficiency induced non-alcoholic fatty liver disease in mice, The differentially expressed genes in liver tissue in “Normal VS model ”and “Model VS SAR” were identified by RNA-seq.

Project description:22 sediments/soils/mosses samples from natural granitic pools located in the Natural Park of Sierra de Guadarrama (near Madrid) Spain.
Project description:To understand microbial community functional structures of activated sludge in wastewater treatment plants (WWTPs) and the effects of environmental factors on their structure, 12 activated sludge samples were collected from four WWTPs in Beijing. GeoChip 4.2 was used to determine the microbial functional genes involved in a variety of biogeochemical processes. The results showed that, for each gene category, such as egl, amyA, nir, ppx, dsrA sox and benAB, there were a number of microorganisms shared by all 12 samples, suggestive of the presence of a core microbial community in the activated sludge of four WWTPs. Variance partitioning analyses (VPA) showed that a total of 53% of microbial community variation can be explained by wastewater characteristics (25%) and operational parameters (23%), respectively. This study provided an overall picture of microbial community functional structures of activated sludge in WWTPs and discerned the linkages between microbial communities and environmental variables in WWTPs.
Project description:To determine whether and how warming affects the functional capacities of the active microbial communities, GeoChip 5.0 microarray was used. Briefly, four fractions of each 13C-straw sample were selected and regarded as representative for the active bacterial community if 16S rRNA genes of the corresponding 12C-straw samples at the same density fraction were close to zero.
