Differentially expressed genes between SPOPmut and control in mouse prostate organoids
Ontology highlight
ABSTRACT: To provide further insight to the signaling pathways deregulated by SPOP mutation and determine the relevance of these models to human prostate cancer, we performed RNA-seq on SPOP mutant organoids and controls. RNA-seq reads mapped to human and mouse SPOP confirmed appropriate expression of the F133V transgenic transcript without overexpression compared to endogenous mouse Spop. Quantification of gene expression was performed via RSEQtools using GENCODE as reference gene–annotation set. Both SPOPmut and SPOPwt were done in the same run. S0 was done in first run; S1 and S2 were done in second run. S3, S4 and S5 were done in third run. S5mut and S5wt were excluded from differentially expressed genes analysis, due to the different mouse line.
Project description:HSC-2 (hepatic stellate cells line from rat) were stably transfected with rno-miR-146a. Three different clones were selected (S1, S4, S5). We used Affymetrix rat genome RAT230 2.0 chip to monitor global transcriptome changes.
Project description:Background: E-cigarette popularity is on the rise in youth and young adults, with mounting concerns regarding the long-term safety of these devices. Cell culture and animal models have highlighted the damaging potential of e-cigarettes, but to date there is a lack of data from human lung tissue to corroborate these findings. Methods: Using human lung tissue obtained during a bullectomy in young adults, we performed RNA-sequencing to uncover e-cigarette related changes to the human lung transcriptome. Information on e-cigarette use habits was collected via questionnaire. Samples included in study: S1, S2, S3, S4, S5, S7, S9, S10, S12, S13, S14, S16, S17, S18, S19, S21
Project description:Dynamical response to oxygen downshift under fermentation conditions was tested by taking sample before (S1) and after (S2, S3 and S4) the oxygen downshift. The dynamical changes relevant for ongoing research on physiology were applied.

The dynamical changes relevant for ongoing research on physiology were applied. Experiment Overall Design: Four microarray chips were analyzed: Experiment Overall Design: S1 was taken 15 min before the oxygen downshift Experiment Overall Design: S2, S3 and S4 were taken 15 min, 45 min and 75 min after the oxygen downshift, respectively
Project description:We analysed transcriptome changes between seed devlopement (4 stages corresponding at before (S1) and after (S2) desiccation tolerance acquisition and before (S3) and after (S4) longevity acquisition) in dissected seed tissues (embryo, E; Endosperm Eo and Seed Coat SC)
Project description:Objectives: The contribution of circular RNAs (circRNAs) in the regulation of embryonic lung development is not yet clear. This study aims to uncover the differentially expressed circRNAs in mouse embryonic lung tissue. Methods: High-throughput sequencing (HTS) was used to determine the cirRNA expression profiles at four time points of mouse embryonic lung tissue [embryonic (E) Day 14.5 (E14.5/S1), (E16.5/S2), (E18.5/S3), and newborn (N) Day 7.5 (N7.5/S4)]. CircRNAs that were significantly differential were subjected to bioinformatic analysis and functional prediction for their host genes. Finally, quantitative real-time reverse transcriptase polymerase chain reaction (qRT-PCR) was conducted to examine their levels. Results: Dynamically expressed circRNAs in the mouse embryonic lung tissue were identified. After that, a total of 231 circRNAs differentially expressed between the three groups (S1 vs. S2, S1 vs. S3 and S1 vs. S4) in embryonic lung tissue (fold change ≥ 2.0; p < 0.05). These circRNAs were subjected to bioinformatic analysis to predict their potential biological functions. Finally, six circRNAs (circRNA3_Ttn, circRNA56_Galnt18, circRNA38_Alg12, circRNA42_Filip1l, circRNA43_Ptprm, and circRNA57_Ncoa3) that were further validated using qRT-PCR. Conclusions: These findings illustrate the vital functions of circRNAs in mouse embryonic lung development. Combined with our results and previous researches, circRNAs may serve as potential miRNA sponges in the embryonic lung development. Our research is conducive to further explore the development of embryonic lungs, and the dynamic expressed circRNAs may be novel molecules that regulate mouse lung development.
Project description:<p>KORA ("Kooperative Gesundheitsforschung in der Region Augsburg" which translates as "Cooperative Health Research in the Region of Augsburg") is a population based study of adults randomly selected from 430,000 inhabitants living in Augsburg and 16 surrounding counties in Germany. The collection was done in 4 separate groups from 1984-2001 (S1-S4). One of the KORA groups, S3/F3, will be utilized for our GWAS because it is the only group with refractive error (RE) measurements. Consequent to informed consent, each of the surveys sampled subjects from ten strata according to age (range 25-74 years) and sex (equal ratio) with a minimum stratum size of > 400 subjects. In the KORA S3 study 4,856 subjects were studied between 1994 and 1995, and 3,006 individuals from S3 returned for follow up between 2003 and 2005 (S3/F3). For this refractive error study, we are including 1,981 subjects from S3/F3 (mean age 55.7, range 35-84). For each subject, eyeglass prescriptions were measured in addition to an evaluation by the Nikon Retinomax. Subjects with predisposing medical conditions, i.e., connective tissue disorders, and ocular conditions i.e., cataract and corneal opacities, that might predispose them to refractive error will not be included for genotyping.</p> <p>Whole genome association genotyping will be performed to determine common alleles that contribute to the variation of the quantitative trait of refractive error.</p>
