Project description:Supplement S1: Figure S1. (a) Effect of culture age of Euglena gracilis on gene expression, determined with gene arrays analysis. Total number of differentially expressed genes classified into groups of fold-change-ranges in Euglena gracilis cells of different culture age (5 d, 9 d, 11 d) compared to culture age of six days. Underlying data are presented under the figure or in “FC in classes”, respectively. The total number of investigated genes on microarray was n = 20296. Data were retrieved from four independent cell cultures. (b) Effect of culture age of Euglena gracilis on gene expression. Fraction of differentially expressed genes in percent of all investigated transcripts [n = 20,396] classified into groups of fold-change-ranges in Euglena gracilis cells of different culture age (5 d, 9 d, 11 d) compared to culture age of six days. Underlying data are presented under the figure or in “FC in classes”, respectively. For more details, please see the legend Figure S1 a. (c) Effect of culture age of Euglena gracilis on gene expression. Fraction differentially expressed genes (DEGs) above (“upregulation”), below (“downregulation”) or above AND below (“all”), respectively a certain threshold (th). In contrast to (b), where the fold changes are provided in classes, all DEGs above, below, or above AND below as certain threshold are summarized. In addition, Supplement S1 contains all raw data about all DEGs detected and a rankling of the genes regarding their fold changes (FCs). Supplement S2: Determination of differential gene expression with respect to culture age in Euglena gracilis, obtained with micro-arrays. The table “Overlapping DEGs” contains all transcripts, which were found to be differentially expressed in Euglena gracilis at all three investigated days of culture age (5, 9, or 11 days, respectively), against the 6-day samples. In the table “Overlapping DEGs ranked”, the data are ranked according to their fold change. Supplement S3: Transcription of Euglena gracilis cells of different culture age (5, 9, and 11 d, respectively) was compared with the transcription of cells after 6 days of culturing. All data were obtained in quadruplicate. This supplementary data show the possible functions of the proteins encoded by the DEGs (differentially expressed genes), which were differentially expressed for the corresponding days. Table “Diff transcripts funct.” gives a general overview about gene expression changes for all days. The other tables list the possible function of the DEGs for each particular day. The lists only contain genes where a function could be assigned. Complete lists of DEGs also including transcripts with unknown function are provided in Supplement S1. Supplement S4: Determination of gene expression changes with respect to culture age in Euglena gracilis samples of cells were analyzed after 5 d, 9 d, and 11 days of growth in batch cultures, and their gene expression was compared with the gene expression of cells with a culture age of 5 d. For each day, the number of differentially expressed genes (DEGs) each showing the same GO terms were summed up. In order to correlate these changes with the number of all genes with the same GO term in Euglena gracilis, data from sequencing projects were employed [1,2]. Genes with the same GO terms were counted and correlated with the number of observed DEGs in Euglena gracilis. In the first table, GO terms of DEGs were assigned to corresponding days of culturing and correlated with the data of [1, 2] (total numbers and ratios). Diagram “Ratio of DEGs compared to Cordoba et al. [%]” visualizes the ratio of DEGs with total data of [7]. The second diagram shows the number of GO terms of DEGs, which were found at day 9 AND day 11. The change between the two days is provided. Data are visualized in the diagram “Fraction of DEGs of a certain GO over time”. Ref. [2]: Additional file 2: Table S1 “proteome”. Ref. [1]: Supplementary Data, Table S2.

Project description:Purpose: The aim of this study is to compare the plasma miRNA profile between mice subject to myocardial ischemia and reperfusion and mice subject to sham operation. Methods: 8 to 10-week old C57BL/6 mice underwent myocardial ischemia and reperfusion (MIR) or Sham operation. Plasma RNA was isolated using Trizol LS reagent 4h post-surgery. NGS cDNA libraries were prepared using Norgen Biotek Small RNA Library Prep Kit. Library quality was validated prior to sequencing on an Illumina NextSeq 500 platform.

Project description:We sequenced and assembled a detailed transcriptome and draft genome for E. gracilis Z1. To improve annotation and investigate gene expression in E. gracilis, where most transcripts are also trans-spliced, we conducted comparative proteomic and transcriptomic analysis between light and dark-adapted E. gracilis. The analysis revealed that alterations to protein abundance are controlled post-transcriptionally, surprisingly similar to trypanosomatids.

Project description:TLR4/NF-κB signaling plays a central mediator in response to danger signals released in the muscle ischemia-reperfusion injury (IRI). This study was designed to profile TLR4/NF-κB-responsive microRNAs (miRNAs) in the skeletal muscles following IRI. Following 2 h of ischemia and subsequent reperfusion for indicated times (0 h, 4 h, 1 d, and 7 d) of the isolated thigh skeletal muscles based on femoral artery perfusion of C57BL/6, Tlr4â/â, and NF-κBâ/âmice, the muscle specimens were analyzed with an miRNA array to detect the TLR4/NF-κB-responsive miRNAs. Male C57BL/6 mice (10â12 weeks of age, 22â35 g) were purchased from BioLasco (Taiwan). Tlr4â/â (C57BL/10ScNJ) and NF-κBâ/â (B6.Cg-Nfkb1tm1Bal/J) mice were purchased from Jackson Laboratory (Bar Harbor, ME, USA). All housing conditions were established and surgical procedures, analgesia, and assessments were performed in an AAALAC-accredited, SPF facility following national and institutional guidelines. Animal protocols were approved by the IACUC of Chang Gung Memorial Hospital. Mice were anesthetized with an anesthetic cocktail consisting of 0.1 mg/g ketamine and 0.01 mg/g xylazine, given as an intraperitoneal injection (0.01 ml/g body weight). After the induction of anesthesia, the mice were restrained in a supine position on a heating pad to maintain body temperature at 37°C. The quadriceps muscle perfused based on the femoral artery of the mouse was carefully isolated away from the femoral bone and the underlying adductor muscle group. In the ischemic group, ischemia was induced by placing a microvascular clamp carefully across the proximal site of vascular pedicle for 2 h and then the microvascular clamp was removed. Good vascular inflow and outflow through the pedicle was verified under direct magnified vision. In the sham-operated control group, the muscle was isolated without microvascular clamp being applied. The incision wound was closed with interrupted sutures (4-0 nylon) and the animals were allowed to awaken in the remaining periods of reperfusion. The harvested muscles were frozen in isopentane chilled in liquid nitrogen and stored at -80°C. For the miRNA array experiments, the isolated skeletal muscles of C57BL/6 mice after 2 h of ischemia and 0 h, 4 h, 1 d, and 7 d of reperfusion as well as of Tlr4â/âand NF-κBâ/â mice after 2 h of ischemia and 1 d of reperfusion were used in 3 replicate experiments.
