Figure 4(A-C) Simulated predictions of sim expression dynamics during continuous opto-Notch activation under different molecular perturbations. Row 1 shows the wild-type model behaviours. Rows 2-3 show the response to a knock-out of a negative regulator of sim expression, which could be either the internal inhibitor (B) of the adaptation motifs (row 2) or an attenuator that in wild-type dampens the activation of (A) (row 3). Row 4 simulates the stabilization of (A) in its active state by reduction of either the inhibitory action of (B) or the auto-inactivation of (A). Note that these perturbations generally lead to a loss of adaptive behaviour, with the exception of the attenuator knock-out on state-dependent inactivation (C; row 3). (D-E) Results of continuous activation experiments in a Hairless heterozygous hypomorphic mutant (Hairless H2) and under overexpression of Twist (Twist OE) The observed outcomes are most consistent with the predictions from the state-dependent inactivation model. (F) Proposed model of Notch nuclear adaptation: NICD induces target gene expression by triggering an active state of the Promoter-Enhancer Complex (EPC). Continuous activation leads to a state-dependent transition of the EPC into an inactivated refractory state. Hairless reduces the effective activation rate whereas Twist reduces the effective inactivation rate.

The positive feedback is indicated through the arrowhead while the bar at the end of the arrow refers to negative feedback. B Time lapse images showing simulations of the coupled STEN-CEN model demonstrating CEN (top) and STEN (bottom) waves spreading in space. The threshold was lowered by increasing positive feedback of STEN (perturbation) at time 0. The white arrow (time 0, CEN) denotes a wave at a high threshold that disappears in the next image, while the red arrow (time 25, CEN) points to a lowered threshold wave that enlarges and spreads. C A 3D representation of simulation waves under high (left) and low (right) threshold waves propagating in time. D Quantification of simulated wave speed before and after threshold lowering (+perturb). Statistics are from 8 simulations. Error bars are from the student's t-test.

Figure 7(A) Histological analysis of plaque-associated BACE1 immunoreactivity in female APP23p40+/+ (n=8) and APP23p40-/- (n=10) mice. BACE1 area covered was normalised to 4G8-positive area covered of the same image (left). Right: representative images, scale bar = 50 µm. Mean ± s.e.m., statistical analysis: two-tailed unpaired t-test, p=0.5402. (B) Stereological quantification of the number of cortical GFAP-positive astrocytes in female APP23p40+/+ (n=8) and APP23p40-/- (n=8) mice (left). Right: representative images of GFAP staining, scale bar = 200 µm. Mean ± s.e.m., statistical analysis: two-tailed unpaired t-test, p=0.1579. (C) Quantification of activated microglia within 30 µm from plaque borders. Top: Numbers of Iba1-positive microglia were normalised to the size of the nearest 4G8-positive plaque and quantified in female APP23p40+/+ (n=8) and APP23p40-/- (n=10) mice. Mean ± s.e.m., statistical analysis: two-tailed unpaired t-test, p=0.8240. Bottom: Histogram representing Clec7a staining intensity within plaque-associated Iba1-positive microglia in female APP23p40+/+ (n=8) and APP23p40-/- (n=10) mice. Mean ± s.e.m., statistical analysis: two-tailed unpaired t-test with Bonferroni correction for each single bin, p=N.S.. Right: representative images, scale bar = 40 µm. (D) Radial intensity profiles of Iba1 and 4G8 around the center of the nucleus of plaque-associated Iba1-positive microglia in female APP23p40+/+ (n=8) and APP23p40-/- (n=10) mice. Iba1 intensity declines until a radius of ~6 µm, marking the cell periphery. 4G8 intensity peaks inside the cell (~4 µm), but stays high outside the cell. This is very likely due to the close proximity to 4G8 positive plaques. Mean ± s.e.m., statistical analysis: two-tailed unpaired t-test with Bonferroni correction for the number of binned radii shows no significant difference between both 4G8 traces.

| Endothelial kugeln are transient and dynamically alter shape and size.Figure 2MIPs of a time-series light sheet acquisition shows three different kugeln (kugel 1 - black arrowhead; kugel 2 - grey arrowhead; kugel 3 - unfilled arrowhead) protruding and retracting from parent vessels (2min intervals; inverted LUT). Kugeln persisted for variable durations before regression into the parent vessel (43 kugeln from 9 4dpf embyros; 4 experimental repeats). MIPs taken 20min apart showing examples of different kugel behaviour including shape changes (asterisk), expansion (circle), retraction (triangle), or little change (pentagon). MIPs taken 1h apart show that kugeln may be observed at one time-point (red arrowhead, 55:20:00) but not 1h later in the same animal (56:20:00) and to develop on other vessels 1h later (57:20:00) which again have regressed by 58:20:00. Kymographs generated by line-scanning across the diameter of a typical kugel shows that kugel diameter oscillated with a periodicity of minutes, while no such oscillations were observed in adjacent similarly sized cerebral vessels (all images grey LUT; inverted).
Figure 4A. Localization of endogenous YAP and NLK in low (LD) or high density (HD) MCF10A (upper panel) or NIH3T3 cells (bottom panel) was examined by indirect immunofluorescence. Nuclei were stained with DAPI. Scale bars: 20 μm. B. Level of NLK decreases in a cell density-dependent manner. Lysates from low (LD) and high density (HD) of MCF10A, HEK293T, and NIH3T3 cells were immunoblotted with antibodies indicated in the figure. C. Level of endogenous NLK mRNA is unaffected, whereas the expression of YAP target genes was reduced, at high cell density. Quantitative real-time PCR analyses for expression of AMOTL2, CTGF, CYR61, and NLK in low (LD) and high density (HD) NIH3T3 cells were performed. Quantification of AMOTL2, CTGF, CYR61, and NLK mRNA was normalized with the level of Gapdh. Data represent average values from a representative of multiple experiments performed in triplicate. Error bars indicate standard deviations of triplicate measurements. Data are presented as mean ± sem. *P < 0.05 and ***P < 0.005. Student t-test was used for statistical analysis.

Acid sphingomyelinase induces clustering and activation of α5 and β1 integrins in ceramide-enriched membrane domains resulting in tumor cell adhesion and metastasis.Figure 5A-C 1 × 105 B16F10 cells were incubated with (A) 1 U/ml purified acid sphingomyelinase (ASM) or (B) 5 × 107 wild-type (WT), Asm-deficient (Asm−/−) platelets (Plts), or a mixture of 45:55 wild-type:Asm-deficient platelets. Cells were fixed with 2% paraformaldehyde for 15 min and stained with fluorescein isothiocyanate (FITC)-coupled anti-α5 integrin, Cy3-labeled anti-β1 integrin, and Cy5-labeled anti-ceramide antibodies. Samples were analyzed by confocal microscopy. Shown are representative examples from four independent experiments (A, B) or the quantitative analysis of cells positive for ceramide/β1 integrin clusters from at least 100 cells/sample (C). Given is the mean ± SD, n = 4, ANOVA followed by Tukey's multiple comparisons test. P-values are indicated. D ASM-induced B16F10 tumorcell adhesion to fibronectin-coated cover slips is abrogated by the inhibition of integrins with RGD peptides. Shown is the mean ± SD of the number of cells adherent to the cover slip. Statistical significance was determined by ANOVA followed by Tukey's multiple comparisons test. P-values are indicated. E Intravenous injection of CFSE-labeled B16F10 cells into wild-type mice results in formation of ceramide-enriched domains that contain β1 integrin clusters on tumor cells in vivo, while injection of tumor cells into Asm-deficient mice does not result in ceramide and integrin clustering. Please note that the cell in the lower panel still binds a platelet. Shown are representative results from four independent experiments each.

Figure 5 Figure 5. Model describing the drought response of DOG1, which depends on the function of the antisense transcript asDOG1. For a detailed description see the Discussion. Drought causes ABA induction that leads to drought resistance. Part of this response is due to silencing of asDOG1, which results in the induction of DOG1 transcription as shown in the bottom panel (adapted from Fig 1F). The induction of DOG1 expression is required for and contributes to the final ABA-induced drought resistance, as shown in the top panel (adapted from Fig 2A).
