Fig.Figure 2Fig. 2. Spironolactone is the primary candidate recovered from the co-culture screen.(A) Flow chart of the compound screen. PC12 cells (population A) were transfected in-solution with the split TEV assay plasmids ERBB4-NTEV-tevS-GV and PIK3R1- CTEV and incubated for 2 h before seeded onto 96-well plates. Population A cells were allowed to express the plasmids for 24 h. Compounds were added in a concentration of 10 µM, followed by seeding the Nrg1-expressing PC12 cells (population B) half an hour later. After 24 h of compound incubation, cells were lysed and subjected to a dual luciferase assay. The screening data was analyzed using the cellHTS2 package in R Bioconductor. Fig. 2. Spironolactone is the primary candidate recovered from the co-culture screen.(B) Graphic visualisation of the primary screen data of the NIH-NCC library set 1. All counts (320 compounds and 64 controls) from the Nrg1-ERBB4-PIK3R1 split TEV compound screen were plotted against the Z-score using the Mondrian programme, with pathway activators displaying high values and inhibitors low values. For the secondary analysis, we selected all candidates that were at least three standard deviations away from the mean. EGFld positive and Lapatinib/CI-1033 negative controls are shown in red.

Fig.Figure 5Fig. 5 Visualization of transient interactions in fatty acid synthesis. (A) Communities in fatty acid metabolism and the quantification of intra-community distances within cryo-electron micrographs. Fatty acid synthase (FAS) frequently interacts with other sizeable protein complexes in a linear 'pearl-string-like' arrangement and usually localizes at the edges of the community. Scale bars correspond to 25 nm. FAS particles (circles) and their nearest neighbors (arrow heads) are indicated. (C) Related to (A). Calculation of minimum distances between pairs of FAS molecules as well as FAS molecules and their closest non-FAS neighbors in comparison to random distributions. Whereas FAS molecules are randomly distributed, their binders are not, confirming physical interactions. Supervised picking means that all single-particles were manually picked from the images. Randomized distance means that these manually picked particles were assigned random coordinates in each image (randomization of x,y coordinates considering image borders) and then their distance is calculated. (D) Cross-linking mass spectrometry data show that the binder is a carboxylase that is bound to the malonyl transacylase domain and acyl carrier protein (ACP) is in the vicinity, considering cross-link length and the positions of the lysine on the ctFAS structure. Cross-links come from both affinity-purified and fractionated cell extracts. (E) The molecular mechanisms in fatty acid synthesis (Wakil et al, 1983), and the relevance of the position of the ACP (see Fig. 6 for details) and carboxylase to the catalytic cycle is indicated (see text). ACP, acyl carrier protein; CoA, acetyl-Coenzyme A; MPT, malonyl/palmitoyl transferase; KS, ketoacyl synthase; KR, ketoacyl reductase; DH, dehydratase; ER, enoyl reductase; AT, acetyltransferase.

A model for MRN and CtIP functions in endonucleolytic DNA cleavage.Figure 8When phosphorylated CtIP and MRN are present (in S-G2), CtIP phosphorylation is detected by the FHA and BRCT domains of NBS1 (1), which in turn promotes DNA cleavage by MR via direct interaction with MRE11, mediated by the MRE11-interaction region of NBS1 (2). This results in maximal DNA end resection activity compatible with homologous recombination.   In the absence of NBS1 function (see text), CtIP promotes the nuclease of MR in a reaction that is partly independent of its phosphorylation (3). This results in low resection activity of MR, which may be sufficient for limited resection in G1.   In the absence of CtIP, NBS1, through its MRE11-interaction region, but independently of its FHA and BRCT domains, promotes the MR endonuclease (4). This activity is likely very limited and therefore unlikely to be physiologically relevant.
TNF promotes recruitment of innate immune cells and CCL2 expression.Figure 3Anti-Ly6G treatment depletes local monocytes/macrophages at the fracture site. Counts of positively stained infiltrative F4/80+ cells in the adjacent muscle to the fracture site following treatment with control or anti-Ly6G at day 1 and day 7. Data are presented as mean ± SEM. **P = 0.005 at day 1 and **P = 0.002 at day 7, and *P = 0.013 for control at day 1 versus control at day 7, by unpaired two-sided t-test. Addition of 1 ng rhTNF to fracture supernatant in the air pouch model led to increased numbers of neutrophils (Ly6G+, CD11b+ cells) and monocytes/macrophages (Ly6G−, CD11b+, CD115+ cells) in the cellular infiltrate.
