Article Title: Effects of Alternative Splicing-Specific Knockdown of Tjp1 α+ by Rbm47 on Tight Junctions Assembly during Blastocyst Development

doi: 10.1101/2023.07.18.549609

Figure Lengend Snippet: (A) The position of both isoforms of Tjp1 (exon11/12; α+/α-), the α-domain (exon20/21) and two Tjp1 α-specific (exon 19/21; w/o α and alternatively spliced exon 27/28; α-) primers used for cDNA amplification of Tjp1 isoforms. Arrows mark the position and direction of primers used for cDNA synthesis. Transcription levels of Tjp1 α+/-, Tjp1 α variant (B), and Tjp1 α+/-, Tjp1 α-, Rbm47 (C). Transcription levels of Tjp1 α+/α-, Tjp1 α-, and Rbm47, shown as relative quantification (RQ). Error bars represent mean ± standard error.

Article Snippet: Primary antibodies against RBM47 (HPA006347, Sigma-Aldrich), TJP1 α+ (HP9044; Hycult Biotechnology, Uden, Netherlands) and TJP1 α-(HP9045; Hycult Biotechnology) were diluted and incubated with the embryos overnight at 4°C.

Techniques: Amplification, Variant Assay

Article Title: Naringin Exhibited Therapeutic Effects against DSS-Induced Mice Ulcerative Colitis in Intestinal Barrier–Dependent Manner

doi: 10.3390/molecules26216604

Figure Lengend Snippet: Effect of naringin on the expression of inflammatory cytokines in ulcerative colitis mice. ( A ) TNF-α, IL-6 and IL-1β distribution in the colons of each group (immunofluorescence analysis, 200×). ( B ) Concentration of TNF-α in the blood serum. ( C ) Concentration of IL-6 in the blood serum. Data are presented as means ± SD ( n = 3). ## p < 0.01, compared with the control group; * p < 0.05 and ** p < 0.01, compared with the model group.

Article Snippet: Rabbit polyclonal antibodies for TNF-α, IL-6, IL-1β, COX-2, iNOS, Occludin, ZO-1, goat anti-rabbit IgG secondary antibodies and Texas Red conjugated goat anti-rabbit antibody were obtained from ABclonal Technology (Wuhan, China).

Article Title: Chibby1 knockdown promotes mesenchymal-to-epithelial transition-like changes

doi: 10.1080/15384101.2017.1281478

Figure Lengend Snippet: Cby1 KD results in a dramatic increase in ZO-1 protein levels at the plasma membrane. A. IF staining for the epithelial marker ZO-1 in control or Cby1-KD SW480 or HEK293 cells as indicated. Nuclei were visualized with DAPI. Scale bar, 20 μm. B. (Left) Cell lysates from control or Cby1-KD HEK293 cells were subjected to western blotting with ZO-1 and β-actin (loading control) antibodies. (Right) The band intensity of ZO-1 was quantified and normalized to that of β-actin. The results are expressed as mean ± SEM from triplicate samples in a single representative experiment. The control scrambled shRNA is set as 1. * P < 0.05.

Article Snippet: The primary antibodies used were as follows: mouse anti-β-catenin and mouse anti-E-cadherin (BD Transduction Laboratories); mouse anti-ZO-1 (BD Transduction Laboratories).

Techniques: Staining, Marker, Western Blot, shRNA
