Figure Lengend Snippet: ST3Gal1 expression in inflamed IEC monolayers alters MUC2, TFF3, CDX2, STAT3 and p-STAT3 expression. ST3Gal1 knockdown in ST3Gal1-sh3/IEC significantly increased (A) MUC2, (B) TFF3 and (C) CDX2, but significantly reduced (D) STAT3 mRNA levels in the inflamed IEC monolayer. ST3Gal1 OE in ST3Gal1-OE/IEC significantly reduced (E) MUC2, (F) TFF3 and (G) CDX2 mRNA levels in the inflamed IEC monolayer. (H) ST3Gal1 OE in ST3Gal1-OE/IEC slightly decreased STAT3 mRNA levels in the inflamed IEC monolayer. (I) Western blotting showed no changes in protein expression in non-inflamed knockdown samples. (J) Western blotting showed that MUC2, TFF3 and CDX2 protein levels were increased, and p-STAT3 expression was decreased in the inflamed IEC monolayer comprising ST3Gal1-sh3/IEC. (K) Western blotting showed no notable changes in protein expression in non-inflamed OE samples. (L) Western blotting showed that MUC2, TFF3 and CDX2 protein levels were decreased, and p-STAT3 expression was increased in the inflamed IEC monolayer comprising ST3Gal1-OE/IEC. Data are presented as the mean ± SD. Statistical significance was assessed using one-way analysis of variance followed by Tukey's post-hoc test. *P<0.05 and **P<0.01.

Figure Lengend Snippet: A Phenotypes of patient-derived organoid lines P009T and P013T. B UMAPs of organoid single cell transcriptomes. Organoid lines and medium conditions as indicated. LGR5-ISC stem cell, enterocyte and Goblet cell signatures are visualized. C Schematic representation of SLAM-Seq workflow to infer RNA dynamics (“RNA velocity”). In short, organoids were passaged and assigned to different medium conditions. After three days, nascent RNA was metabolically labelled for 2 h using 4sU. Organoids were harvested, dissociated, and fixed. RNA in single cells was alkylated, and cells were subjected to single cell sequencing. Reads were assigned to nascent or old RNA status, depending on diagnostic T-C mutational status. D Developmental trajectories inferred from RNA metabolic labelling. Bold and thin arrows indicate high versus low directionality of RNA velocity. Colors below RNA velocity show latent time (yellow: early latent time; blue: late latent time). E Activities of Wnt/β-catenin and MAPK target genes in organoid single cell transcriptomes, ordered along latent time. F Activities of TFF3 , FABP1 , MKI67 and MMP7 in organoid single cell transcriptomes, ordered along latent time. Color code for panels D-F: Red: high activity; blue: low activity.

Figure Lengend Snippet: Varying TFF3 expression in an individual sample with mixed histologic subtypes. (A) Immunohistochemistry of TFF3 in a case with both lepidic and papillary areas. The boxed area with a solid line represents the lepidic area, which was enlarged in (B). The boxed area with a dotted line represents the papillary area, which was enlarged in (C). (D) The comparison of lepidic area and papillary/acinar area H-scores in 38 cases with both these areas. Each line represented the H-score of lepidic and papillary/acinar area of each case, and the data revealed a significant increase in papillary/acinar area from 22 of the 38 cases (red line). No differential expression in other samples was marked with a black line. The Wilcoxon signed-rank test was used to determine significance. Scale bar in (A), 1 mm; Scale bars in (B an C), 250 µm.
