Article Title: Therapeutic Intervention Using a Smad7-Based Tat Protein to Treat Radiation-Induced Oral Mucositis.

doi: 10.1016/j.ijrobp.2021.09.039

Figure Lengend Snippet: Fig. 5. Pharmacodynamics markers of Tat-PYC-Smad7 treated dog oral mucositis. (A) Biopsies of posttreatment oral mucosa were evaluated by immunohistochemistry to detect NFkB-p50, pSmad3, pH2AX, and myeloperoxidase. Representative images of vehicle treated and Tat-PYC-Smad7 treated mucosa are presented with the lower panel in each set, presenting a high-power view of the blue box identified in the panel above. Scale bar: 100 mm. (B) Quantification of positive, brown-staining in epithelium sections excluding ulcers (in vehicle group) pictured in panel A. Myeloperoxidase staining together with mor- phology evaluation were used to identify neutrophils (indicated by yellow arrows) in ulcer surface and stroma. Faint brown staining in epithelium is nonspecific. The staining quantification for each dog and the mean of each treatment § standard error of the mean is presented.

Article Title: STAT3 haploinsufficiency is associated with autosomal dominant hyper-IgE syndrome

doi: 10.1126/sciadv.adw2464

Figure Lengend Snippet: ( A ) STAT3 expression was evaluated by Western blot in Stat3 +/+ and Stat3 +/− cells derived from the spleen, thymus, and bone marrow (BM). Tubulin was used as loading control. Each lane represents one mouse. ( B ) A quantification of the STAT3/loading control ratio after normalization is shown for independently performed experiments as in (A). The mean ± SD is plotted. ( C ) IgE serum levels in Stat3 +/+ and Stat3 +/− mice were measured by ELISA. ( D ) Flow cytometry to identify IgG1 + and IgE + cells from IgM − IgD − cells 4 days after culturing Stat3 +/+ and Stat3 +/− B220 + splenocytes with IL-4 (12.5 ng/ml) and anti-CD40 antibody (62.5 ng/ml) in the absence or presence of IL-21 (25 ng/ml). Numbers in dot plots represent cell frequencies. ( E ) Mean (±SD) frequencies of the IgG1 + and IgE + cells as gated in (D). ( F ) Levels of IgG1 and IgE in the supernatant of cell cultures as done in (D) were measured by ELISA. B220 + splenocytes from Stat3 +/+ and Stat3 +/− mice were stimulated for different time points with IL-21 (50 ng/ml) ( G ), IL-10 (50 ng/ml) ( H ), and IL-6 (50 ng/ml) ( I ), and the phosphorylation of STAT3 (p-STAT3) was evaluated by flow cytometry. Mean (±SD) of mean fluorescent intensity (MFI) is plotted. Data are representative of at least three independent experiments. P values by unpaired t test (C) or two-way ANOVA followed by Bonferroni’s or Tukey’s multiple comparisons test (B and E to I).
