Figure Lengend Snippet: Minor macroscopic effects of Parp14 deficiency on the severity of salmonellosis. ( A, B ) Schematic representation of the single-animal experiment executed in this study. The blue box refers to mice, which were subjected to statistical comparisons throughout the study. The tissues marked with an asterisk were longitudinally cut into two pieces, one for histology and one for qPCR/RNA-Seq. Images were partially created with BioRender.com. ( C ) Weight change of the mice during the course of the experiment relative to day −1 (medians with interquartile range). No statistically significant differences between the infected wt and Parp14-deficient mice were detected. Statistical significance values are shown in the figure. Weights of the PBS mice were not statistically compared (NA, not applicable; fewer than three animals to compare, see ). ( D ) Colon lengths at day 1 and day 5. ( E ) Spleen weights at day 1 and day 5. ( F ) Liver weights at day 1 and day 5. ( G–L ) Determination of viable bacteria in different tissues at day 1 and day 5. Bars in sub-panels D–L represent medians with interquartile range. All individual data points are shown. Statistical significance values for the differences between the infected wt and Parp14-deficient mice are shown in each D–L sub-panel. Fecal pellets were not obtained from all mice. Parameters of the PBS mice were not statistically compared (NA, not applicable; fewer than three animals to compare, see ).

Figure Lengend Snippet: Quantitation of Parp14 expression in the mouse gastrointestinal tract. ( A ) The QuPath-based quantitation of Parp14 expression. Representative examples of the Parp14 stainings are shown in . The values on the y -axis refer to the means of DAB staining intensity, that is, the mean OD in the QuPath data output. Each dot refers to a single cell. The numbers of analyzed cells (mostly epithelial cells) are indicated on the x -axis (see ). The red lines above the data points refer to the mean values. Statistical analyses were conducted using the two-tailed unpaired t -test (NA, not applicable; fewer than three animals to compare, see ). One Salmonella -infected day 5 mouse was left out from the quantitation due to poor quality of the FFPE tissue block. ( B ) The qPCR data on relative Parp14 expression (means with standard deviation, statistics performed using two-tailed unpaired t -test). Samples were included in the data analysis if they passed the 0.5 standard deviation Ct filter for replicate runs. No statistical analyses were executed against the PBS groups because there were less than three data points/animal to compare (see ). The calibrators in each sub-panel are the mean dCq values of the day 1 Salmonella -infected mice.

Data from a triplicate RNA-Seq analysis of mouse large intestine sections 1 day post-infection are shown. ( A ) The Venn diagrams of shared and unique genes that were detected to be expressed in the infected wt and Parp14-deficient mice (FPKM value >1). The integer is the number of genes detected to be expressed in both of the genotypes. ( B ) The pie charts of the numbers of identified GO terms based on the genotype-specific lists of expressed genes (BP, biological process; CC, cellular component; MF, molecular function; ). ( C–E ) Bar graph representation of all the identified GO BP terms with the genotype-specific lists of expressed genes. The BP terms are sorted based on the percentage of GO term gene values (number of detected genes in a particular BP term / number of all genes in particular BP term × 100). FDR refers to the false discovery rate value. An FDR value cut-off of <0.05 was used in the searches. The asterisks in the wt sub-panel ( D ) refer to the seven infection- and inflammation response-related BP terms. The sub-panel E displays the genes of these seven infection- and inflammation response-related BP terms. ( F–H ) Pathway-enrichment dot plot representations of all (KO sub-panel) and the top 10 (wt sub-panel) KEGG pathways identified with the genotype-specific lists of expressed genes. All the identified KEGG pathways with the corresponding gene lists are described in . The KEGG pathways are sorted based on the P -value. The count values refer to the number of genes that were detected in a particular KEGG pathway. The asterisk in the wt sub-panel ( G ) refers to the only KEGG pathway with a <0.05 P adj -value. The sub-panel H displays the genes of this IL-17 signaling pathway.

Figure Lengend Snippet: Hampered expression of four cytokines in the large intestine of S . Typhimurium-infected Parp14-deficient mice. Four hit genes of the large intestine bulk tissue RNA-Seq analysis ( Ccl2 , Ccl7 , Cxcl10 , Il1b ) were analyzed. Five other TaqMan qPCR assays on inflammation-associated genes were run in parallel. The figure illustrates the TaqMan qPCR data on relative gene expression with means and standard deviations. The calibrators in all sub-panels are the mean dCq values of the day 1 infected wt mice. Statistical analyses were done with a two-tailed unpaired t -test. All the statistical significance values of the comparisons between the wt and Parp14-deficient mice are indicated.
