Project description:As a test of trypanosome transcriptome responsiveness, we analysed the effects of over-expression of the early endosome small GTPase Rab5A in procyclic form T.brucei, which results in significant augmentation of fluid phase and receptor-mediated endocytic activity (Pal et al. 2002).<br><br>part 1: 2 PCFWT and 2 PCF5AWT-OE (PCF cell lines over-expressing a wildtype version of RAB5A) biological replicates, as well as dye swaps were used.<br><br>part 2: 2 PCFWT and 2 PCF5AQL-OE (PCF cell lines over-expressing a mutant version of RAB5A locked in the GTP-bound state) biological replicates, as well as dye swaps were used.<br><br>part 3: 2 PCFWT and 2 PCF5BQL-OE (PCF cell lines over-expressing a mutant version of RAB5B locked in the GTP-bound state) biological replicates, as well as dye swaps were used.
Project description:The goal was to investigate whether the induction of gene expression by vascular endothelial growth factor (VEGF) in endothelial cells depends on endosomal GTPases Rab5A or Rab5C.
Project description:The Bae, Cpx, Psp, Rcs and ?E pathways constitute the Escherichia coli signaling systems that detect and respond to alterations of the bacterial envelope. Contributions of these systems to stress response have previously been examined individually; however, the possible interconnections between these pathways are unknown. Here we investigate the dynamics between the five stress response pathways by i) determining the specificities of each system with respect to signal inducing conditions, and ii) monitoring global transcriptional changes in response to transient over-expression of each of the effectors.
Project description:Secretome analysis through SILAC mass-spectrometry was performed to test how the expression of RAB5A affects protein secretion in MCF10DCIS.com breast cancer cell lines.
