Simple Western: beta-Actin Antibody (AC-15) [NB600-501] - iPSC-RPE from an ARB donor show reduced levels of Best1 expression compared to five different iPSC-RPE control lines. (A) To compare Best1 protein expression levels between different iPSC-RPE lines, beta -actin was used as a loading control. (B) While iPSCs displayed no detectable Best1 protein expression, all shown iPSC-RPE lines – regardless of donor origin – displayed detectable Best1 protein expression. (C) The three control iPSC-RPE lines derived from unrelated, unaffected donors all exhibited similar levels of Best1 protein expression. The dad exhibited reduced levels compared to the unrelated controls & the mom showed levels that were about 50% that of the dad. This was expected as the antibody used cannot detect the mutant Best1I366fsX18 which both the mom & the ARB patient are heterozygous for. Best1 expression levels in the ARB iPSC-RPE line were about a quarter of the levels observed in the Mom 214 iPSC-RPE clone. (D) Widefield immunofluorescent staining of Best1 reveals basolateral staining in each of the iPSC-RPE lines, indicating that Best1 protein is properly localized regardless if Best1R141H and/or Best1I366fsX18 are present. Immunofluorescent signal was notably weaker in the ARB iPSC-RPE clones than in the control clones.

The B6 variant of NLRP1B is not cleaved by LF but can form an inflammasome in response to proteolysis.(A) The amino acid sequence of the first 244 residues of NLRP1BB6 was aligned to the homologous sequence of NLRP1B129. The arrow above the alignment indicates the LF-cleavage site in NLRP1B129. Asterisks indicate sites of amino acid identity. (B) For detection of NLRP1B expression, 293T cells were transfected with the indicated amounts of and empty vector (V) or plasmids encoding GFP-HA-NLRP1B129 or GFP-HA-NLRP1BB6 (construct schematics and the predicted molecular weight of each protein is depicted in the upper panel). Cells were treated overnight with anthrax lethal toxin protein (LeTx, 1μg/ml) 24h post-transfection, and then lysates were analyzed by immunoblotting (IB) with the indicated antibodies. For NLRP1 expression and cleavage, CASP1 and IL1B were omitted to prevent cell death and resulting apparent differences of expression. For blots probed with anti-HA (NLRP1B), the lysates were not boiled prior to loading to prevent aggregation and smearing of full-length and FIIND-processed NLRP1B on the immunoblot. To visualize the N-terminal processed form of NLRP1B, the lysates were boiled and resolved on a separate gel. (C) 293T Cells were transfected with the same amount of titrated NLRP1B encoding plasmid and treated as in B, but transfections also included plasmids encoding mouse CASP1 (200ng), IL-1 beta (200ng) and 200ng of empty vector. (D) For detection of NLRP1B expression, 293T cells were transfected for 36h with 250ng of plasmids encoding WT 129 or B6 NLRP1B or mutants engineered to express the TEV-protease site. Each plasmid was co-transfected with either 100ng of empty vector (V) or plasmids encoding TEV-protease (pTEV) or lethal factor protease (pLF), supplemented with 300ng empty vector (pMSCV). Cells were not treated with LeTx and lysates were analyzed by immunoblotting as in (B). (E) Cells were treated as in C, but with 8ng of plasmids encoding NLRP1B, along with 200ng of plasmids encoding mCASP-1 and mIL-1 beta , and 200ng empty vector to normalize plasmid quantities. Lower quantities of NLRP1B were transfected as compared to panel D so to avoid spontaneous NLPR1B activation. For panels B-E, data shown are representative of at least three similar experiments.

(B) 293T cells were transfected for 36h with 200ng empty vector (V) or plasmids pcDNA3.1-HA-NLRP1B129 or -NLRP1AB6-MYC (CMV promoter) along with 200ng mCASP1 and 200ng mIL-1 beta expression vectors. Cells were treated overnight with anthrax lethal toxin (LeTx, 1μg/ml) 24h post-transfection, and then lysates were analyzed by immunoblotting (IB) with the indicated antibodies. (C) 293T cells were transfected for 36h with plasmids encoding 400ng GFP-HA-NLRP1B129 or GFP-HA-NLRP1AB6 (under the control of the LTR promoter in pMSCV) or with mutants engineered to contain an N-terminal TEV protease site. Cells were also co-transfected with 100ng empty vector (V) or plasmids encoding TEV-protease (pTEV) or lethal factor protease (pLF), plus 300ng empty pMSCV. (D) To assess IL-1 beta cleavage, cells were transfected as in C, but with 8ng of GFP-HA-NLRP1B and co-transfected with vectors encoding 200ng mCASP1 and 200ng mIL-1 beta .

<b>Biological Strategies Validation. </b>Normoxic pre-treatment sensitizes glioma cells to radiation after graded chronic hypoxic (GCH) exposure. The results of anchorage-independent colony forming assays are shown for U87, U87-luc, GL261 glioma cells and 0308 GSCs after 5 Gy radiation exposure under varying O2 conditions. For easier comparisons among cell types, raw values are expressed as a % of the cell type's negative (non-irradiated) control and the means & SEMs are plotted. Each result represents at least 3 independent samples, plated in triplicate. Holm-Sidak comparisons for multiple groups were used for statistical comparisons of raw values (*p N) localization in three microscopic viewing areas were counted as shown in the lower panel. The total counted cell numbers ranged from 35 to 64. The experiments were repeated more than twice, except for the cell localization count, & the results were reproduced.

Diminished permeability of liver sinusoids in Plvap-deficient mice.Neither by immunohistochemistry with antibodies against CD31 (A) nor by light microscopy of 1 µm semi-thin sections (B, Richardson's stain) obvious differences are detected with regards to the overall orientation and the density of liver sinusoids between 3-week-old Plvap-/- mice and wild-type littermates. Sinusoids of Plvap-deficient mice show a higher number of macrophages in their lumen (white arrows) and focal areas with accumulations of mononuclear cells in Disse's space (black arrows). Lower panels in B show higher magnifications. C, After perfusion of a wild-type animal with FITC-dextran, a strong FITC-signal (green) throughout the liver is detected. Immunolabeling with CD31 (red) suggests that FITC-dextran molecules have accumulated in the space of Disse. In contrast, in the Plvap-deficient littermate, the signal for FITC-dextran is much weaker and barely detectable. Nuclear DNA is labeled with DAPI (blue).

Scale bar = 100 μm. *, P < 0.05; **, P < 0.01; ***, P < 0.001; n = 5; post hoc Bonferroni multiple comparison test for tumor cell density and microvessel density, and post hoc Dunn test for VCAM-1 expression. Tumor core was delineated from the infiltrative border as indicated by the blue and red lines, respectively. Expression of Ki67, nestin, and SOX2 has been normalized to tumor area. **, P < 0.01; matched Wilcoxon test.
