Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to analysis the differiational genes and pathways in CON and PMB treatment cells by using RNA-seq Methods: CON and PMB treatment cells mRNA profiles were generated by deep sequencing, using Illumina Novaseq. The sequence reads that passed quality filters were analyzed at the transcript isoform level with following methods: Alignment by using HISAT2 , IGV was used to to view the mapping result by the Heatmap, histogram, scatter plot or other stytle, FPKM was then calculated to estimate the expression level of genes in each sample, EdgeR software was used for differential gene expression analysis and Function Enrichment Analysis including GO enrichment analysis and KEGG . Conclusions: Our study represents detailed analysis of CON and PMB cells transcriptomes, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of mRNA content within a cell or tissue. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions.
Project description:Congenital obstructive nephropathy (CON) is the leading cause of chronic kidney disease (CKD) in children. CON is a complex disease process involving pathological changes in kidney development and function that occur as a result of obstructed antegrade urine flow beginning in utero. The megabladder (mgb-/-) mouse is an animal model of CON that develops kidney disease secondary to a bladder-specific defect in smooth muscle development. Expression levels of specific microRNAs were compared by microarray analysis on the Agilent platform and by quantitative PCR (qPCR) of kidney samples from wild type and mgb-/- mice.
Project description:Compared the global gene expression profiles of HD- and CON-iPSC-derived neurons We used microarrays to detail the global programme of gene expression for comparing the global gene expression profiles of HD- and CON-iPSC-derived neurons and facilitating studies of medium spiny neurons (MSN)-degenerative processes of Huntington's Disease (HD).
Project description:Purpose: The goals of this study are to find the mechanisms of mesenchymal stem cells (MSC) ameliorating concanavalin A (Con A) induced inflammatory mice Methods: Liver tissues were harvested at 6h, 12h after Con A injected with/without MSC (n = 3 per group) for transcriptome profiling. Results: Filter the raw data obtained fromDNBSEQ-G400, and compare the filtered clean reads to the reference sequence. Quantitative analysis of known genes and new genes, differential expression analysis based on gene expression in different sample groups, GO function analysis, Pathway function analysis, cluster analysis, and protein interaction for the selected differentially expressed genes Network, transcription factor coding ability prediction and other in-depth mining analysis. Conclusions: Our study discoveres following processes were significantly affected: apoptosis, MAPK signaling pathway and cytokine-cytokine receptor interaction.
Project description:Compared the global gene expression profiles of HD- and CON-iPSC-derived neurons We used microarrays to detail the global programme of gene expression for comparing the global gene expression profiles of HD- and CON-iPSC-derived neurons and facilitating studies of medium spiny neurons (MSN)-degenerative processes of Huntington's Disease (HD). By using a step-wise in vitro differentiation protocol combining EB formation, neural induction by small molecules, treatment with inhibitors of the TGFß pathway (SB431542) and the BMP pathway (LDN193189), and mechanical isolation/purification of neural progenitors and neurons, we induced 60-70% of control iPSCs or HD-iPSCs to differentiate into GABA- and DARPP-32- double positive neurons.
Project description:Poly(ADP-ribose) polymerases (PARPs) modify target proteins with ADP-ribose by using nicotinamide adenine dinucleotide as a substrate, and contribute to various signaling pathways. PARP14 is the largest member of PARP superfamily. Whole RNA-sequencing analysis was performed and analyzed by Lc. Biotech Co., Ltd. (Hangzhou, China). Primary mouse microglia from the Con + ACT-Con group, Con + ACT-PARP14 group, OGD + ACT-Con group, and OGD + ACT-Con group were collected in TRIzol. Total RNAs were extracted from Trizol. UMI technology was used to label each sequence fragment with sequence tags, which minimized the interference of duplication caused by PCR amplification on the quantitative accuracy of the transcriptome. RNA sequencing reads were aligned to the mouse genome (GRCh37/hg19) using the software Hisat2 (2.0.4). Transcript abundance was evaluated by calculating fragments per kilo base of exon per million fragments mapped (FPKM).
Project description:To explore the effect of Bicd2 in Con A-induced acute autoimmune hepatitis, we conducted single cell RNA sequencing of AAV-scramble or AAV-shBicd2 infected mice livers in response to Con A injection.
