Article Title: Non-stem cell lineages as an alternative origin of intestinal tumorigenesis in the context of inflammation

doi: 10.1038/s41588-024-01801-y

Figure Lengend Snippet: a . GSEA plot of Paneth cells from NWD1- vs. AIN76A-fed mice. The DSS signature significantly associates with the NWD1 diet (NES 2.99, Padj 2.5e-56). P value denote Benjamini-Hochberg adjusted value of the two-sided enrichment P-value from GSEA. b . Bar plot showing pathways elevated (P < 0.05, NES > 0.5) in Paneth cells from NWD1- when compared to AIN76A-fed animals. c . Prediction scores for Paneth (left) and goblet (right) cells on UMAP embedding from the scATAC data (Choi et al. ). d . Unsupervised clustering reveals two distinct clusters (c5, c20) that include Paneth cells. e. Bar plot listing gene ontology (GO) results based on differential peaks from the diet responsive Paneth cells. Pvalues were obtained from the EnrichR GO analysis and denote the results of Fisher’s exact test f . Immunofluorescence imaging of WGA and Olf4m showing intestinal crypts from mice fed with AIN/NWD1 diets. Asterisks earmark double positive cells. Scale bar indicates 10 µm.

Figure Lengend Snippet: a , Schematics of the experimental approach designed to investigate the consequences of short- and long-term exposure to a western-style diet (NWD1) versus control (AIN-76A) diets. b , Heatmap showing z -scored DSS signature (DSS versus control; P adj < 0.05, log 2 -transformed fold change > 0.25) in PCs exposed to DSS or NWD1. c , Organoid multiplicities derived either from single ISCs or PCs, and from reconstituted doublets (L, Lgr5 + ISCs; P, PCs). Pooled data from n = 4 independent experiments. P values were calculated using one-way ANOVA and Tukey’s tests for group comparisons. Error bars depict s.d. d , Representative image of lineage tracings from a NWD1-fed Lyz1 -YFP mouse. Scale bars, 50 μm. The P value depicts the result of a two-sided Student’s t -test and the error bars represent s.d. Data from n = 3 mice. e , UMAP showing PCs from mice fed AIN-76A (AIN) and NWD1 ( n = 3 mice per condition). The DSS signature portrayed on UMAP embedding highlights a subcluster of PCs responsive to the NWD1 diet. f , Violin plots showing different levels of the DSS signature (top) and CytoTRACE score (bottom) between PCs responsive to the NWD1 diet and other PCs. P values show the significance of a two-sided Wilcoxon test. g , Violin plots representing marker genes of PCs responsive to the NWD1 diet, showing coexpression of stem and secretory markers. h , Heatmap visualization of GSVA, indicating pathways that are activated in PCs after exposure to DSS or NWD1. Comparison with data from ref. . i , UMAP plot of PC subset in the scATAC dataset of mice treated with AIN ( n = 2) and NWD1 ( n = 2). j , Heatmap listing differential peaks between diet response PCs and other PCs. k , Ideogram displaying the distribution along the mouse chromosomes (Chr) of the differential peaks observed upon diet response (red) when compared with those characteristic of PCs (blue).

Article Title: Molecular Characterization of the Fragilysin Pathogenicity Islet of Enterotoxigenic Bacteroides fragilis

doi:

Figure Lengend Snippet: Nucleotide sequences used to define the ends of the fragilysin pathogenicity islet. The nontoxigenic sequence was from B. fragilis VPI 2553. Toxigenic sequences across the left and right ends of the pathogenicity islet were from enterotoxigenic B. fragilis strain VPI 13784. Lowercase letters represent where the sequence from the nontoxigenic strain varied from the sequence flanking the ends of the islet. A 17-bp sequence present only in DNA from the nontoxigenic strain is boxed. Arrows indicate the ends of the islet and corresponding nucleotide number. Direct repeats (DR) are underlined.
