Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
This study was undertaken in order to characterize the functions of Rex-1 and identify potential Rex-1 target genes.Both alleles of the Rex-1 gene were disrupted in J1 mouse embryonic stem cells. Gene expression levels in one of the resulting Rex-1 knockout cell lines was compared to that of J1 wild type cells.

Description
Purpose: Unlike in most adult-onset cancers, an association between typical paediatric neoplasms and inflammatory triggers is rare. We studied whether immune system related genes are activated and have prognostic significance in Ewing sarcoma family of tumours (ESFT). Experimental design: Data-analysis was performed on gene expression profiles of 44 ESFT patient, 11 ESFT cell line, and 18 normal muscle tissue samples. 238 inflammation related genes were selected based on literature and a macrophage gene expression signature was derived from SymAtlas. Differential expression of the genes was analysed by t-test and survival analysis was performed according to gene expression.

Description
The improvement of Ewing's sarcoma (EWS) therapy is currently linked to find strategies to select patients with poor and good prognosis at diagnosis and to generate modified treatment regimens. In this study, we analyze the molecular factors governing EWS response to chemotherapy in order to identify genetic signatures that may be used for risk-adapted therapy.

Description
It is possible to identify the key genes and pathways involved in specific physiological processes using transcriptome analyses. However, these powerful new deep sequencing-based methods have rarely been applied to studies of memory function. We used the bow-tie maze to train rats by exposing them to highly familiar objects or to novel objects. Total RNA sequencing was then used to compare the transcriptome of the perirhinal cortices of naïve control rats and rats exposed to novel and familiar stimuli. Differentially expressed genes were identified between group Novel and group Familiar rats and these included genes coding for transcription factors and extracellular matrix-related proteins. Moreover, differences in alternative splicing were also detected between the two groups. To conclude, this study shows that RNA sequencing can be used as a tool to identify differences in gene expression in behaving animals undergoing the same task but encountering different exposures. Overall design: RNA profiles of perirhinal cortex from rats exposed to novel objects (n=5) or familiar objects (n=5) in a recognition memory task were investigated using the Ion Proton System. Controls were naïve rats that had not undergone any behavioural testing (n=4).
