Article Title: Dietary polyamines promote intestinal adaptation in an experimental model of short bowel syndrome

doi: 10.1038/s41598-024-55258-4

Figure Lengend Snippet: Polyamines enhance mucosal defense factors in rats with massive intestinal resection. (A-B) Fecal and serum secretory IgA was measured using ELISA. n = 5–7/group. (C) IgA in ileum tissue was assessed using western blotting. n = 4–6/group. (D) Fecal mucin was measured using a fluorometric assay. n = 4–6/group. (E) Representative images of ileal villus showing immunostaining by Muc2 (original magnification, ×400; scale bars = 200 μm). Left graphs show the number of goblet cells per unit villous area and the size of goblet cell secretion granule. (F) The expression of Claudin-3 in the ileum tissue was measured by western blot analysis. Representative images of ileal villus showing immunostaining by Claudin-3 (original magnification, ×200; scale bars = 100 μm). (G) Serum DAO was measured by ELISA. n = 5–7/group. (H) Serum GLP-2 was measured by ELISA. n = 5–7/group. (I) Fecal short-chain fatty acid (SCFA) content was measured using high-performance liquid chromatography. n = 3–6/group. Data are presented as mean ± SD. Results of one-way ANOVA are represented as follows: * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001.

Article Snippet: Nonspecific antibody binding was blocked using 15% goat serum for 30 min. For staining of Ki-67, Muc2, and Claudin-3, the slides were then incubated with anti-Ki67 antibody (ab16667; Abcam, Cambridge, UK), anti-Muc2 rabbit monoclonal antibody (M01212-1; Boster Biological Technology, Pleasanton, CA, USA), and Claudin-3 polyclonal antibody (#PA5-32353; Invitrogen, Waltham, MA, USA) at 4°C overnight, respectively.

Article Title: Ectoine Enhances Mucin Production Via Restoring IL-13/IFN-γ Balance in a Murine Dry Eye Model

doi: 10.1167/iovs.65.6.39

Figure Lengend Snippet: Ectoine enhances production of secreted mucins in DS mice. ( A , C ) Representative images of IF staining showing the decreased production of MUC5AC ( A ) and MUC2 ( C ) in DS mice (DS+PBS) was recovered by ectoine eye drops (DS+Ect); Scale bars = 50 µm. The stitched images were made because the cornea and conjunctiva in some eyeball sections were too far apart to be captured on the same image. ( B , D ) IF intensity quantified the alternation of MUC5AC and MUC2 in 3 groups; each circle represents one eye. Data are shown as Mean ± SD, n = 6; the P values are shown in the graph as compared with the DS+PBS group.

Figure Lengend Snippet: Gene expression of MUC5AC, MUC2, MUC1, MUC4, MUC16 , and MUC15 by conjunctiva and cornea. ( A ) Gene expression of all 6 mucins in normal mice were detected at different mRNA levels based on the threshold cycle (Ct) value in real-time PCR with house-keeping gene GAPDH as an internal control. ( B ) The mRNA levels of all six mucins in conjunctiva of the three groups of mice. ( C ) The mRNA expression of MUC1, MUC4, and MUC16 by corneas in the three groups of mice. Data are shown as Mean ± SD, n = 6; the P values are shown in the graph as compared with the DS+PBS group.

Lanes: M, PGM in Tris buffer; 1, PGM plus F837/76; 2, PGM plus F837/76 plus protease inhibitor; 3, PGM plus F837/76 plus protease inhibitor, EDTA free; 4, Tris buffer plus F837/76. Arrows highlight differing protein bands. (B) Growth of strain F837/76 in mMOD minimal medium after addition of 0.25% PGM. (C) Mucin degradation by F837/76 cells and supernatant (s). PGM type II and type III were used. (Left) Western blot with MUC2 specific antibody. (Right) Sypro Ruby staining of the same samples as a control. Arrows indicate MUC2 as well as differing protein bands.
