Transcriptome profiling of wild type and DNMT3L-overexpressing Drosophila larvae brains

ABSTRACT: The objective of the study was to examine the gene expression changes caused by human DNMT3L overexpression in Drosophila melanogaster brains. There were 6 samples in total- C1, C2, C3, D1, D2, and D3. C1-C3 were larvae brains from the strain of elavC155-Gal4, which were used as the control group (C). D1-D3 were larvae brains from the strain with DNMT3L overexpression, which were bred by crossing the strains of elavC155-Gal4 and w/w;P(UAS-DNMT3L,w+)/Cyo;TM2/TM6B and used as the DNMT3L overexpressing group (D). The total RNA of each sample was extracted from 30 brains of the 3rd instar larvae of Drosophila by using TRIzol reagent. Then the RNA samples were processed for high throughput transcriptome sequencing on Illumina HiSeq 3000 platform. Results: among 17737 cleaned RNAs, 267 RNAs were differentially expressed in DNMT3L overexpressing group compared with control group, with q-value ≤ 0.05 and |fold change|≥2 , with more down-regulation (151) than up-regulation (116). They corresponded to 655 human homologous genes. The differential expressed genes distributed in all chromosomes. Functional annotation with GO and KEGG enrichment revealed the top functional groups including calcium ion transport, voltage gated channel, choilnergic synapse, serotonergic synapse, and drug metabolism.

RNA-seq of HTNV-infected murine bone marrow-derived macrophages (mBMDM) from 0 to 36 hours

Project description:The murine bone marrow-derived macrophages (mBMDMs) were infected with Hantaan viruses (HTNV) with an MOI of 1, or mock-infected with Co60-inactivated HTNV. The mBMDM RNAs were extracted for RNA sequencing (RNA-seq) at 0 (mock-infected), 12, 24, and 36 hours post-infection (hpi). Each group contained three repeats (mBMDM from three different C57/6L mice). The data of 0 hpi group (labeled as A) were shown as A1, A2 and A3.The data of 12 hpi group (labeled as B) were shown as B1, B2 and B3. The data of 24 hpi group (labeled as C) were shown as C1, C2 and C3. The data of 36 hpi group (labeled as D) were shown as D1, D2 and D3.

Expression data from murine fibroblasts overexpressing Fbxl10

Project description:Posttranslational modifications on histone tails control gene expresssion levels in an either positive or negative way. Therefore enzymes which modifiy the modifications on the histon tails, like histone demethylases, are able to strictly regulate the transcriptom. To analyse the regulatory role of histone demethylase Fbxl10 we generated a stable cell line permanently overexpressing HA-tagged Fbxl10 and identified the transcriptome changes compared to untransfected control cell line by microarray. Tet-off Mefs were transfected with a plasmid containing HA-Fbxl10 cDNA and a Hygromycin resistence plasmid and cell clones were selected for HA-Fbxl10 expression. Three independent RNA samples were generated from untransfected Tet-off Mef cells (C1-C3) and from Tet-off Mef HA-Fbxl10 (D1-D3) and hybridisated on Affymetrix microarray.

Data of mass spectrometry analysis of proteins interactingwith fibroblast activity protein in dysplastic oralkeratinocyte cells

Project description:This project adopts mass spectrometry proteomics technology for research. The experiment was divided into four groups: the experimental group was D1 group, D2 group, and the control group was D3 group and D4 group(D2 is the repeating group of D1, and D4 is the repeating group of D3）. The experimental group and control group were treated with mouse monoclonal anti FAP antibodies (SC-100528; Santa Cruz Biotechnology, Dallas, TX, USA) and normal mouse IgG antibodies (A7028, Beyotime Biotechnology), respectively. A total of 700 proteins were identified in four samples, of which 290 were false positive proteins. The remaining 290 proteins were only positively expressed in the D1 group, 62 proteins were only expressed in the D2 group, and 121 proteins were both positively expressed in both D1 and D2 groups. Based on the above data, a systematic analysis was conducted on all identified proteins in combination with bioinformatics.

Whole-genome expression data from purified larval Drosophila LNv pacemaker neurons

Project description:We generated whole genome expression profiles from a homogeneous population of purified pacemaker neurons (ventral Lateral Neurons, LNvs) from wild type and clock mutant Drosophila. The study identifes a group of genes whose expression is highly enriched in LNvs compared to other neurons; and a second group of genes rhythmically expressed in LNvs in a clock-dependent manner. Drosophila larval brains (L3 stage) were taken from a 12:12hr light entrainment regime and dissected at ZT-3 or ZT-15. Larvae contained either Pdf-Gal4:UAS-GFP transgenes or Pdf-RFP to label the 8 LNvs pacemaker neurons per brain, allowing purification by flow cytometry. Brains were dissociated and LNvs purified by FACS, followed by RNA amplification and hybridization on Affymetrix microarrays.

Batch wt vs hyper +_- pABA Normal int_Filtered fg-bg2

Project description:Transcriptional analysis upon the overexpression of the folate gene cluster on a high copy plasmid when compared to an empty vector in the lactic acid bacterium L. plantarum. The transcriptional response was determined for both strains in the presence and absence of pABA thereby using the hybridisation sceme as described in the data processing section. Keywords: response to folate gene cluster overexpression and pABA treatment The batch experiment with and without pABA scheme consisted of a loop design with 21 microarrays with the following samples hybridized on one array and labeled with Cy3 and Cy5, respectively: C1+P and F1+P, F1+P and C2+P, C2+P and F3+P, F3+P and C3+P, C3+P and F2+P, F2+P and C1+P, C1+P and C2+P, F2+P and F3+P, C1-P and F1-P, F1-P and C2-P, C2-P and F3-P, F3-P and C3-P, C3-P and F2-P, F2-P and C1-P, C1-P and C2-P, F2-P and F3-P, C3-P and F1+P, F2+P and C1-P, C2+P and F3-P, F1-P and C3+P, and F2+P and F1-P. Here, C1+P, C2+P, C3+P, F1+P, F2+P, and F3+P represent biological triplicates of the L. plantarum harboring pNZ7021 and pNZ7026, respectively, when grown in batch in the presence of pABA. The C1-P, C2-P, C3-P, F1-P, F2-P, and F3-P, represents the L. plantarum harboring pNZ7021 and pNZ7026, respectively, when grown in batch in the absence of pABA.
