Project description:We report for the first time movement of Correia Repeat Enclosed Elements, through inversion of the element at its chromosomal location. Analysis of Ion Torrent generated genome sequence data from Neisseria gonorrhoeae strain NCCP11945 passaged for 8 weeks in the laboratory under standard conditions and stress conditions revealed a total of 37 inversions: 24 were exclusively seen in the stressed sample; 7 in the control sample; and the remaining 3 were seen in both samples. These inversions have the capability to alter gene expression in N. gonorrhoeae through the previously determined activities of the sequence features of these elements. In addition, the locations of predicted non-coding RNAs were investigated to identify potential associations with CREE. Associations varied between strains, as did the number of each element identified. The analysis indicates a role for CREE in disrupting ancestral regulatory networks, including non-coding RNAs. RNA-Seq was used to examine expression changes related to Correia repeats in the strain

Project description:miRNA Expression in Quadriceps Muscle from Cofilin-2 Null Mice Compared to WT Littermates on Day 7 Quadriceps muscle resected on day 7 from cofilin-2 deficient mice and wildtype littermates were collected and mIRNA was isolated. Expression changes were analyzed by microarray.
Project description:To confirm the anti-metastatic effect in bladder cancer cell lines, the PDK4 gene was knocked down and phosphorylated protein changes were compared through LC-MS/MS analysis.
Project description:We previously found that the SF3A mRNA splicing complex was required for a robust innate immune response; SF3A acts in part by inhibiting the production of a negatively acting splice form of the TLR signaling adaptor MyD88. Here we inhibit SF3A1 using RNAi and subsequently perform an RNAseq study to identify the full complement of genes and splicing events regulated by SF3A in murine macrophages. Surprisingly, SF3A has substantial specificity for mRNA splicing events in innate immune signaling pathways compared to other pathways, affecting the splicing of many genes in the TLR signaling pathway to modulate the innate immune response. RNAseq was used to monitor the effects of SF3A1 siRNA-mediated knockdown in murine macrophages. Three biological replicates were used for each of the four treatment combinations (with/without siRNA, with/without LPS). The first replicates for each combination were each sequenced in two runs, which were combined in the analysis.
