Description
5-Fluorouracil (5-FU) is a widely used chemotherapeutic drug in colorectal cancer. Previous studies showed that 5-FU modulates RNA metabolism and mRNA expression. In addition, it has been reported that 5-FU incorporates into the RNAs constituting the translational machinery and that 5-FU affects the amount of some mRNAs associated with ribosomes. However, the impact of 5-FU on translational regulation remains unclear. Using translatome profiling, we report that a clinically relevant dose of 5-FU induces a translational reprogramming in colorectal cancer cell lines. Comparison of mRNA distribution between polysomal and non-polysomal fractions in response to 5-FU treatment using microarray quantification identified 313 genes whose translation was selectively regulated. These regulations were mostly stimulatory (91%). Among these genes, we showed that 5-FU increases the mRNA translation of HIVEP2, which encodes a transcription factor whose translation in normal condition is known to be inhibited by mir-155. In response to 5-FU, the expression of mir-155 decreases thus stimulating the translation of HIVEP2 mRNA. Interestingly, the 5-FU-induced increase in specific mRNA translation was associated with reduction of global protein synthesis. Altogether, these findings indicate that 5-FU promotes a translational reprogramming leading to the increased translation of a subset of mRNAs that involves at least for some of them, miRNA-dependent mechanisms. This study supports a still poorly evaluated role of translational control in drug response.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
There have been few studies that have focused on the periplaque regions surrounding demyelinated plaques, especially in spinal cords. Areas of incomplete demyelination have been demonstrated but poorly studied. The present study aimed to analyze the molecular immunopathology of periplaque demyelinated lesions (PDLs) in the spinal cord of patients with secondary progressive multiple sclerosis (MS).

- Illumina HumanHT-12 V4.0 expression beadchip
Description
This study aimed to generate a new panel of comprehensively, genomically characterized high-grade serous ovarian carcinoma (HGSOC) cell line and xenograft models. Multidimensional genomic data were generated and compared between cell lines/xenografts and the tumours they were derived from, indicating the cell lines/xenografts are highly similar to their patient-matched tumours. Cell line/xenograft data were also compared to TCGA ovarian tumours to show the cell lines are good models of clinical HGSOC.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
In mammalian cells, AU-rich elements (AREs) are well known regulatory sequences located in the 3' untranslated region (UTR) of many short-lived mRNAs that suppress gene expression at the posttranscriptional level. Tis11, a zinc finger RNA-binding protein homologous to mammalian tristetraprolin, targets ARE-containing reporter mRNAs for rapid degradation in SL2 cells. To identify Drosophila mRNA targets of Tis11, we performed genome-wide expression profiling after dsRNA-mediated depletion of endogenous Tis11 in SL2 cells. Furthermore, we studied the involvement of Tis11 in regulating the Drosophila immune response by profiling mRNA expression after LPS treatment, in the presence or absence of Tis11.
