We examined the role of ATG7 during the process of CD8 T cell memory formation. In the absence of ATG7, antigen-specific CD8 T cells failed to survive past the contraction phase and failed to give rise to memory cells. We used microarrays to examine the global programme of gene expression underlying changes introduced in the absence of the ATG7 gene and identified distinct classes genes varied their expression during this time-point. Mouse LCMV-specific CD8 T cells were isolated at day 8 post LCMV infection for RNA extraction and hybridization on Affymetrix microarrays. We sought to compare the gene expression profiles in wild-type cells and cells lacking the ATG7 gene during the peak of their expansion.

ID_REF = VALUE = Signal ABS_CALL = indicating whether the transcript was present (P), absent (A), or marginal (M) DETECTION P-VALUE = Biotinylated cDNA were prepared from NuGEN Ovation V2 Amplification System according to the standard protocol from total RNA. Following fragmentation, cDNA were hybridized over-night at 45C on GeneChip Mouse Genome Array. GeneChips were washed and stained in the Affymetrix Fluidics Station. QIAgen RNeasy Plus kit was used to extract total RNAs from the isolated cells according to manufacturer's instruction GeneChips were scanned using a high resolution confocal scanner. Protocol Type normalization data transformation protocol labelling protocol hybridization protocol nucleic acid extraction protocol array scanning protocol Experimental Factor Name genotype Experimental Factor Type genotype Comment[SecondaryAccession] GSE57047 Comment[GEOReleaseDate] 2014-10-26 Comment[ArrayExpressSubmissionDate] 2014-04-24 Comment[GEOLastUpdateDate] 2014-10-26 Comment[AEExperimentType] transcription profiling by array SDRF File E-GEOD-57047.sdrf.txt
