Insulin release at 2 mmol/L and 20 mmol/L glucose of 1020 replicates of three mouse islets per Eppendorf tube: (A) pre-cultured alone, with 10 nmol/L C3a alone or with 100 nmol/L C3a alone, for 48 h followed by subsequent GSIS assays in the absence of exogenous C3a; (B) pre-cultured alone, with 5 nmol/L ANXA1 alone or with 10 nmol/L C3a alone for 48 h followed by subsequent GSIS assays in the absence of exogenous C3a or ANXA1; (C) pre-cul- tured alone, with 5 nmol/L ANXA1 alone or with a dual combination of 5 nmol/L ANXA1 and 10 nmol/L C3a for 48 h followed by subse- quent GSIS assays in the absence of exogenous C3a and/or ANXA1, P < 0.05 versus islets pre-cultured alone at the same glucose concentration. (D) Protection from cytokine-induced apoptosis following a 48 h pre-culture with 5 nmol/L ANXA1-alone, 10 nmol/L C3a alone or a dual combination of 5 nmol/L ANXA1 and 10 nmol/L C3a, and the subsequent presence of specified MSC biotherapeutics during the final 20 h cytokine incubation. Eight to 12 replicates of five islets per well in each culture group assayed, *P < 0.05 versus islets pre-cul- tured alone in the presence of cytokines for the final 20 h of the 3-day culture period. The P values (AD) were calculated using two-way ANOVA Bonferroni’s post hoc test.

Article Title: Msx Homeobox Genes Act Downstream of BMP2 to Regulate Endometrial Decidualization in Mice and in Humans

doi: 10.1210/en.2019-00131

Figure Lengend Snippet: Msx2 is a downstream target of BMP2 signaling in the uterus during decidualization. (A) The primary cultures of mouse endometrial stromal cells (MESCs) were transduced with adenovirus expressing GFP or BMP2. The cells were lysed at different time points, as indicated. Total RNA was isolated, and real-time PCR was performed to analyze the levels of Msx2. The relative levels of gene expression were determined by setting the expression level of the GFP-treated sample at 24 h to 1.0 (n = 3). Rplp0, encoding a ribosomal protein, was used to normalize the level of RNA. *P < 0.05. (B) The nucleotide positions of the SBEs on the Msx2 promoter were analyzed by ChIP. (C) Mouse stromal cells were treated with E + P or E, P, and BMP2 (E + P + BMP2) for 90 min. ChIP, using the Smad4 antibody, was performed, as described in “Materials and Methods.” Chromatin enrichment was quantified by real-time PCR using primers flanking the potential SBE in the Msx2 promoter and also a negative control region in the ORF of Msx2. Enrichments were normalized to 1% of input DNA. The experiment was repeated twice, and representative data are shown.

Article Snippet: The next day, the cells were either treated with E + P or E + P + BMP2 (recombinant human BMP2; R&D Systems; 355-BM-010) for 90 minutes.

Figure Lengend Snippet: MSX1 and MSX2 mediate BMP2-induced HESC decidualization. The primary cultures of HESCs were established as described in “Materials and Methods.” The cells were transduced with adenovirus expressing GFP or BMP2. The cells were lysed at different time points as indicated. Total RNA was isolated, and real-time PCR was performed to analyze the levels of MSX1 and MSX2. The relative levels of gene expression were determined by setting the expression level on day 0 of the GFP-treated sample at 1.0. RPLP0, encoding a ribosomal protein, was used to normalize the level of RNA. Data were collected from three independent clinical samples, which were subjected to the same experimental conditions. *P < 0.05; **P < 0.005.
