Deficiency (Df) lines for all four chromosomes obtained from the Bloomington stock center were used to identify dominant modifiers of mutant dVCP in a genetic screen. For the primary screen, balanced virgin female dVCP R152H (recombined with Gmr GAL4) flies were crossed with Df/Balancer males from 270 deficiency lines and progeny were examined for changes in eye phenotype (including color, ommatidia structure and bristle formation). At least ten progeny were examined and scored on a twenty-point scale. Eyes were examined for the presence of: supernumerary inter-ommatidial bristles (IOBs), IOBs with abnormal orientation, necrotic patches, a decrease in size, retinal collapse, fusion of ommatidia, disorganization of ommatidial array and loss of pigmentation. Points were added if: there was complete loss of IOBs (+1), more than 3 small or 1 large necrotic patch (+1), retinal collapse extended to the midline of the eye (+1) or beyond (+2), loss of ommatidial structure in less than 50% (+1) or more than 50% (+2) of the eye, and if pigmentation loss resulted in change of eye color from red to orange (+1) or pale orange/white (+2). Gmr, GAL4, UAS dVCP R152H / Balancer served as an internal control. In a secondary screen to filter nonspecific modifiers of cell death, deficiencies defined as hits (either enhancing or suppressing the dVCP mutant phenotype) were then crossed with flies expressing the pro-apoptotic gene Reaper (recombined with Gmr GAL4). Any hits that similarly affected dVCP R152H and Reaper in the secondary screen were excluded from further study due to the possibility of non–specific anti-apoptotic effects. As regions of interest were identified from the primary and secondary screens, additional Df lines were obtained that overlapped with interacting deficiencies to verify and refine the position of potential modifiers. For the final step of gene identification, individual RNAi lines corresponding to the genes within the candidate intervals were obtained from the Vienna Drosophila RNAi Center. Gmr GAL4, UAS dVCP R152H females were crossed with males from the RNAi lines and the progeny eyes were evaluated for changes. A modifier was defined as an RNAi line that replicated the enhancement or suppression of the corresponding deficiency.

To maximise detection rates and reduce false negative results, two primer sets targeting the highly conserved EBV regions, EBNA-1 and BHRF-1, were used for PCR amplification (Table 1). EBNA-1 is a latent protein required for replication and genome maintenance and is the only viral protein consistently expressed in EBV-infected cells [32 (link),33 (link)]. BHRF-1 is expressed in lytic infection and confers anti-apoptotic properties similar to Bcl-2 for enhancing cell survival [34 (link)]. Groups 2-5 were evaluated by both PCR targets, while inadequate sample volume limited testing to EBNA-1 in Group 1. The beta-globin gene targeting the TAL57 region was used as a 'house-keeping' gene to control for PCR inhibitors and check for DNA integrity [35 (link)]. All samples were subjected to beta-globin PCR prior to EBV QPCR. Contamination was monitored by the use of PCR-grade water and no template DNA controls.

Although this article aims to introduce the PELE web server, we will give here a short description of previous benchmark studies. Several applications have described exit and entry pathways, comparing its accuracy with experimental data. In our first study (14 ), we obtained the migration for Cytochrome P450 camphor, myoglobin and the fatty acid-binding proteins. Further studies compared PELE’s migration pathways in truncated haemoglobin with kinetic experimental data for the wild-type and the W8F mutant (19 (link)). More recently, a comprehensive study on 97 difficult induced fit cases, including cross- and apo- docking, has shown the capabilities of PELE in docking refinement (15 (link)). Furthermore, the study underlined the goodness of the OPLS interaction energy when scoring docking poses within one ligand. Binding site search and induced fit docking has been performed, in collaboration with experimental studies, in aryl-alcohol oxidase (20 (link),21 (link)), in mTOR kinases (22 (link)), in anti-apoptotic Bcl-2 receptors (23 (link)) and in different globins (10 ). The mTOR and Bcl-2 studies illustrate the combination of PELE with docking scoring techniques to discriminate different ligands. At the level of protein dynamics, in absence of ligand, we have compared PELE’s conformational search with microsecond MD simulations in ubiquitin and with metadynamics calculations on T4 lysozyme (16 ). The results clearly show a good agreement in the sampling of PELE with that of more sophisticated simulations.

The cDNA of human CD5L (hsCD5L) was obtained by gene synthesis (GenScript) following NCBI reference sequence NP_005885.1, with a modification in which the immunoglobulin g chain signal peptide replaced that of CD5L. The cDNA was cloned into the p.evi vector and transiently transfected into CHO K1 cells using the eviFect system (Evitria AG). Cells were grown in eviMake, a chemically defined, serum-free, animal component-free medium. The cell culture supernatant fraction was harvested at d 8 after transfection, dialyzed to 20 mM Na2HPO4, pH 7.4 and subjected to MonoQ chromatography. Recombinant human CD5L (r-HsCD5L) was eluted in a sodium chloride gradient, and purification was monitored by SDS-PAGE. Purified protein was dialyzed to PBS, concentrated by centrifugation on Amicon ultra (Millipore, UFC901024), and possible endotoxin contamination was removed by Endotrap columns (Hyglos GmbH, 321063), following the manufacturer´s protocol and as performed before.5 (link) As mentioned above, the purified r-HsCD5L was tested in preliminary experiments, where its activity in terms of MФ TNF secretion, as well as inhibition of apoptosis induced by cycloheximide treatment, was comparable to that of commercially available r-HsCD5L (R&D Systems) (data not shown).

FIG. 10—(A) Effect of NPD1 and VLC-PUFA C32:6 and C34:6 in mediating upregulation of SIRT1 in ARPE-19 cells. (B) Quantification of SIRT1 upregulation by NPD1, C32:6 and C34:6. SIRT1 (Sirtuin1) belongs to a family of highly conserved proteins linked to caloric restriction beneficial outcomes and aging by regulating energy metabolism, genomic stability and stress resistance. SIRT1 is a potential therapeutic target in several diseases including cancer, diabetes, inflammatory disorders, and neurodegenerative diseases or disorders. Elovanoids induce cell survival involving the upregulation of the Bcl2 class of survival proteins and the downregulation of pro-apoptotic Bad and Bax under oxidative stress (OS) in RPE cells. The data in this Figure suggest that elovanoids upregulate SIRT1 abundance in human RPE cells when confronted with OS. As a consequence, remarkable cell survival takes place. This target of elovanoids might be relevant to counteract consequences of several diseases associated with SIRT1.

FIG. 8—(A) Bcl-xL-upregulation by elovanoids ELV1 and ELV2 in ARPE-19 cells under stress. Bcl-xL is the antiapoptotic Bcl2 family protein. Like proapoptotic proteins Bid and Bim, the effect of elovaniod precursors on the antiapoptotic protein Bcl-xL was tested in this figure in RPE cells under OS. Results showed that elovaniod precursors were able to upregulate the Bcl-xL protein in RPE cells under stress, which is the opposite effect of Bid and Bim. (B) Effect of NPD1, ELV1 and ELV2 on Bax expression in LOX-D cells under stress. Proapoptotic Bax was tested in this figure. It is evident that elovaniod precursors downregulated the Bax upregulation by OS in RPE cells under OS, which is consistent with our inhibition of apoptosis experiments, as shown before. C) VLC-PUFA and elovanoids ELV1 and ELV2 mediated effect on Bax upregulation in ARPE-19 cells under stress. In this experiment, elovanoid precursors along with VLC-PUFA were tested on the downregulation of the Bax protein in RPE cells under stress.
