Wells in 384-well plates were challenged with a temperature step from 25°C to 42°C for 120s (Fig. 1). A final concentration of 25 µM 2APB was added on the same plates to determine the sensitivity to 2APB. Separate plates were prepared for stimulation by a final concentration of 1.75 mM camphor. Concentration-response curves were obtained from three wells for a given compound concentration.

Benchmarking PELE's Computational Efficiency
Cited 6 times
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.

Metabolomic Analysis of Lung and Prostate Cancers

All the experiments were conducted according to the study protocol that was approved by the Institution Review Board of the National Cancer Center, Japan. Informed consent was obtained from all the participants.
Tumor and surrounding tissues were surgically resected from nine lung and seven prostate cancer patients, who had been administered with no anticancer drugs or medications that could greatly modify their metabolisms previous to the surgical treatments. Clinical information on the patients is listed in Table 1. The resected tissue samples were immediately frozen in liquid nitrogen and stored at −80 °C until metabolite extraction. Sample tissues were weighed and completely homogenized by multi-beads shocker (Yasuikikai, Osaka, Japan) at 2,000 rpm for 3 min, after adding 0.5 ml ice-cold methanol containing 50 μM methionine sulfone and camphor-10-sulfonic acid as internal standards. The homogenates were mixed with 0.5 ml chloroform and 0.2 ml ice-cold Milli-Q water. After centrifugation at 2,300×g for 5 min, the supernatant was centrifugally filtrated through 5-kDa cut-off filters (Millipore, Bedford, MA, USA) at 9,100×g for 3 h to remove proteins. The filtrate was centrifugally concentrated in a vacuum evaporator, dissolved with Milli-Q water, and analyzed by CE-TOFMS.

Leaves harvested from the 4th and 5th nodes of Stevia plants grown in the greenhouse for 3 weeks were homogenized in liquid nitrogen. Three hundred fifty milligrams of leaf powder was extracted with 350 μL of ethyl acetate containing 20 μg/mL of camphor (Sigma-Aldrich) as an internal standard. After 3 h incubation at room temperature with constant shaking, the ethyl acetate fraction was transferred into a new tube and treated with anhydrous Na2SO4. The treated extracts were then filtered through a 0.45 μm nylon centrifuge tube (Corning, USA). The GC-MS analysis was performed on Agilent 7890A GC (Agilent Technologies, USA) system as described previously [12 (link)].

Detecting Large Indels in Genomic Data
To obtain CSs of the unclear regions defined above, we analyzed fastq files by LoMA and constructed CSs with the following parameters:
-b3000 -s2000 -h10 -d3 -r0.5 -m1000
We then called indels (≥ 100 bp) found in the CSs using CAMPHOR [3 (link)].

Detecting Structural Variants from WGS Data
To detect SVs from the two samples, we applied LoMA to the WGS data. We first searched for target regions (unclear regions) by scanning all chromosomes from telomere to telomere. We split each autosome and sex chromosome binned per 500 bp, step size 250 bp, and defined an “unclear” region as follows: (1) average coverage between 10 and 200, (2) total number of reads containing indels (≥ 100 bp) or hard- or soft-clipped sequences (≥ 500 bp) > 10, and (3) the proportion of reads containing indels (≥ 100 bp) or hard- or soft-clipped sequences (≥ 500 bp) > 0.2 (Fig. 2A). Then, multiple bins within 10 kbp were merged into one bin. We defined each merged bin as an unclear region in this study. After defining the unclear regions for both NA18943 and NA19240, we collected reads mapped within 10 kbp from both ends of each unclear region using SAMtools [24 (link)].

Whole-genome LoMA analysis. A. The workflow of the whole-genome analysis. Unclear regions were first defined based on the alignment status (indels and clips) of ONT reads. Reads mapped to the regions were separately collected. For each region, LoMA attempted a localized assembly to obtain CSs. CAMPHOR collectively detected structural variants from the CSs for NA18943 and NA19240. B. The relative density of unclear regions of NA18943 and NA19240 are shown in red- and blue-colored heatmaps, respectively. The light-colored regions are dense with unclear regions. The white arrows indicate the autosomal centromeres except chromosome 6. The arrows on chromosome 6 represent the HLA region. C. The precision of indels to the standard SV set was assessed for NA19240. The left vertical axis (bar graphs) shows the number of indels found in each bin (the number of constitutive reads). The right (line graphs) shows the precision of indels in each bin. Both graphs were binned per 2 reads

Characterization of Agricultural Waste
Four external carbon sources were used in this experiment. Agricultural waste RS and CC were purchased from Henan Gongyi Hengrun Water Treatment Materials Co., Ltd. (China). Before the experiment, the agricultural waste was washed with deionized water and dried in a drying oven at 60°C until constant weight. PCL and PHBV were purchased from the Dongguan Camphor Wood Suyuan Plastic Raw Materials Business Department (China). The physical properties of the selected materials are presented in Table 1. The Brunauer–Emmett–Teller surface area, pore-volume, and pore size were obtained by using fresh carbon source materials placed in static tubes, pumped to vacuum and degassed with Micromeritics Tristar II 3020 (USA), and measured in liquid nitrogen after depressurization and cooling.
