Mesodiencephalic dopaminergic (mdDA) neurons control locomotion and emotion and are affected in multiple psychiatric and neurodegenerative diseases, including Parkinson's disease (PD). The homeodomain transcription factor Pitx3 is pivotal in mdDA neuron development and loss of Pitx3 results in programming deficits in a rostrolateral subpopulation of mdDA neurons destined to form the substantia nigra pars compacta (SNc), reminiscent of the specific cell loss observed in PD. We show here that in a ...[more]
Project description:Expression profiles of colorectal liver metastasis samples collected from Paul Brousse Hospital (France) and University Hospital Utrecht (The Netherlands). Patients are divided into a high-risk (DFS < 1 year) and a low-risk group (DFS < 1 year).
Project description:To identify mRNA substrates for the human RNase MRP complex, we examined the effects of siRNA-mediated depletion of RNase MRP (and RNase P) on the transcriptome of HEp-2 cells. The expression of two RNase MRP protein components, hPop1 and Rpp40, was knocked-down and after 48 hours mRNA was isolated from these cells as well as from cells transfected with an siRNA targeting the GFP mRNA (siEGFP), which was used as a control. The expression levels of mRNAs were analyzed on a genome-wide scale using 21K microarrays.
