ABSTRACT: Transcriptional profiling of whole nymphs and larvae from Rhipicephalus microplus at day 4 and 7 post infestation, respectively. This enabled the identification of transcripts that are stage-specific or shared among the stages tested. Reference pool design: Each tissue tested was compared to a reference pool comprising ticks (immature to adult stages) sampled on day 4, 5, 7, 13, 15 and tissues collected on day 20 post infestation. Biological replicates: 2; Technical replicates: 2.
Project description:Transcriptional profiling of salivary gland, midgut and ovary tissues isolated from Rhipicephalus microplus females at day 20 post infestation. This enabled the identification of transcripts that are tissue-specific or shared among the tissues tested. Reference pool design: Each tissue tested was compared to a reference pool comprising ticks (immature to adult stages) sampled on day 4, 5, 7, 13, 15 and tissues collected on day 20 post infestation. Biological replicates: 2; Technical replicates: 2.
Project description:Transcriptional profiling of midgut tissues isolated from Rhipicephalus microplus and Rhipicephalus decoloratus females at day 20 post infestation. This enabled the identification of transcripts that are species-specific or shared between the two tick species tested. A direct comparison (Balanced block) was performed: Midgut tissues collected on day 20 (post infestation) from R. microplus was compared to that of R. decoloratus. Biological replicates: 3 ; Technical replicates: 1.

Project description:Dasatinib has demonstrated efficacy in patients with chronic-phase chronic myeloid leukemia (CML) who had resistance or intolerance to imatinib. However, some patients also develop resistance or intolerance to dasatinib. To identify potential molecular pathways involved in primary resistance to dasatinib in CML, we analyzed gene expression profiles of mononuclear cells of 7 imatinib-resistant patients, collected before and after 1-year dasatinib treatment. Large-scale gene expression was measured with Agilent microarrays covering protein-coding genes and long (>200 nt) noncoding RNAs (lncRNAs). Sets of genes and lncRNAs significantly differentially expressed (>1.5 fold-change; q value ≤10%) were identified. Ingenuity Pathway Analysis pointed to a number of functions, canonical pathways and gene networks that were significantly enriched with differentially expressed genes. In addition to protein-coding genes, lncRNAs have been recently implicated in pathways leading to tumorigenesis. Our data point to new possible regulatory elements involved in dasatinib resistance in CML. This SuperSeries is composed of the SubSeries listed below. Refer to individual Series.

Large-scale gene expression was measured with Agilent microarrays covering protein-coding genes and long (>200 nt) noncoding RNAs (lncRNAs). Sets of genes and lncRNAs significantly differentially expressed (>1.5 fold-change; q value ?10%) were identified. Ingenuity Pathway Analysis pointed to a number of functions, canonical pathways and gene networks that were significantly enriched with differentially expressed genes. In addition to protein-coding genes, lncRNAs have been recently implicated in pathways leading to tumorigenesis. Our data point to new possible regulatory elements involved in dasatinib resistance in CML. Dasatinib pre-treatment and 1-yr post-treatment samples from 3 responders (R) or 4 non-responders (NR) chronic myeloid leukemia (CML) patients were investigated. We analyzed expression of Pre-treatment R vs. Pre-treatment NR; Pre-treatment R vs. Post-treatment NR; Pre-treatment NR vs. Post-treatment NR.
Project description:Investigation of whole genome transcription expression level changes in Drosophila mojavensis wild-type populations (Las Bocas:LB and Punta Prieta:PP). The experiment was designed to investigate life history transcriptomics in different environments. A total of 172 hybridizations were performed in this entire experiment. We used 135K 12-plex NimbleGen arrays. Total RNA was recovered from each sample listed below. The experimental design consisted a total of two populations (Las Bocas:LB; Punta Prieta:PP), two host diets (Agria:AG and Organ pipe:OP) and fourteen life stages (6 hr egg:E6; 1st instar larvae:L1; 2nd instar larvae:L2; 3rd instar larvae:L3; Early pupal stage:EP; Late pupal stage:LP; 0 Day old adult:0D; 3 Day old adult:3D; 4 Day old adult: 4D; 6 Day old adult:6D; 10 Day old adult:10D; 14 Day old adult:14D; 18 Day old adult:18D & 24 Day old adult:24D). Each chip measures the expression level of 14528 transcripts. Two to 5 replicates were used for each type (R1, R2, R3 etc.). Fly source details are as follows: Las Bocas 2009: LB09; Punta Prieta 2008:PP08.
Project description:The objective of this study was to identify porcine genes which expression was affected in vitro stimulation with LPS from Salmonella typhimurium. Microarray experiment was conducted to reveal genes being significantly differentially expressed in LPS stimulated versus unstimulated porcine alveolar macrophages from two from healthy pigs The comparison was done LPS alveolar macrophages versus unstimulated alveolar macrophages sampled from two healthy pigs. The experiment was conducted as common reference design.
Project description:LncRNAs and mRNAs expression profile of MEFs comparing senescent cells with young cells. The microarray with coverage of 41597 mouse lncRNAs and 35291 mouse mRNAs. In the study presented here, six samples were analyzed. Biological replicates: three Senescent MEFs, three Young MEFs, independently grown and harvested.
