Figure Lengend Snippet: Transcriptional signature downregulated in S . Typhimurium-infected Parp14-deficient mice. Data from triplicate bulk tissue RNA-Seq analysis of mouse large intestine sections 1 day post-infection are shown. ( A ) Inter-sample correlation heatmap based on the FPKM values of the DEGs in Parp14-deficient vs wt mice comparison. R 2 is the square of Pearson correlation coefficient ( R ). ( B ) Volcano plots of the DEGs. Specific information on the DEGs is given in . The x -axis shows the fold difference in gene expression between different samples, and the y -axis shows the statistical significance of the differences. Red dots represent upregulation genes, and green dots represent downregulation genes. The dashed line indicates the threshold line for statistically significant differential gene expression. The values marked with asterisks refer to the number of DEGs that were used for a stringent downstream data analysis, that is, UP genes, log2(FoldChange) > 0.5 and P adj < 0.05; DOWN genes, log2(FoldChange) < −0.5 and P adj < 0.05 . ( C ) GO term analysis with DEGs in Parp14-deficient vs wt mice comparison (BP, biological process; CC, cellular component; MF, molecular function; ). The GO terms were searched using the canonical Fisher’s test and an FDR value <0.05 filter. ( D ) Bar graph representations of the top 20 identified GO BP terms (all the 107 identified GO BP terms in ) sorted based on the percentage of GO term gene values (number of detected genes in a particular GO term / number of all genes in a particular GO term × 100). The black asterisks in the sub-panel refer to the PB terms with functional relevance to cell adhesion and cytoskeleton remodeling. ( E ) Pathway-enrichment dot plot representations of the top 10 identified KEGG pathways sorted based on the P -value. All the identified KEGG pathways with the corresponding gene lists are described in . The count values refer to the number of genes that were detected in a particular KEGG pathway. The black asterisk in the wt sub-panel refers to the KEGG pathways with a <0.05 P adj -value.
Article Snippet: We used the single-cell RNA-Seq data analysis and visualization interface at the Broad Institute Single Cell Portal ( https://singlecell.broadinstitute.org/single_cell ) in order to analyze Parp1 and Parp14 expression.
