Project description:The aim of this study was to identify the miRNAs in CEF in response to synergistic infection of ALV-J and REV, as well as attempt to reveal the mechanism underlying pathogenesis and immune suppression symptoms.
Project description:We bed ALV-J-susceptible and ALV-J-resistant chickens. In this work, we find the different gene expression between ALV-J-susceptible and ALV-J-resistant chickens
Project description:We bed ALV-J-susceptible and ALV-J-resistant chickens. In this work, we find the difference DNA methylation states between ALV-J-susceptible and ALV-J-resistant chickens
Project description:Purpose: The goals of this study are to investigate the differentially expressed miRNAs between ALV-J-infected primary monocyte-derived macrophages (MDM) and uninfected control by Illumina deep sequencing. Methods:Total RNA from two ALV-J-infected MDM (designated: J3h_1, J3h_2, J36h_1 and J36h_2) and two uninfected MDM samples (designated: NC3h_1, NC3h_2, NC36h_1 and NC36h_2) was isolated by TRIzol following the manufacturer’s instruction at 3 h post infection (hpi) and 36 hpi. RNA samples of two individuals within each group were pooled with equal amounts, and then were subjected to Illumina deep sequencing by Illumina Hiseq 2000. Results: compared to the uninfected MDM, we identified 13 significant up-regulated miRNAs and 2 significant down-regulated miRNAs in ALV-J infected MDM at 3 hpi, and 6 significant up-regulated miRNAs and 2 significant down-regulated miRNAs in ALV-J infected MDM at 36 hpi. Conclusions: Our results suggest that DE miRNAs involved in the immune response induced by ALV-J infection in MDM at 3 hpi. In addition, only 25 miRNAs-target DEGs were identified in MDM with ALV-J infection at 36 hpi, and these target DEGs can’t be significantly enriched in any GO terms and KEGG pathway..
Project description:In order to found the target genes of ALV-miR-p19-01 which encoded by ALV-J, we used RNA-pull down and RNA-seq. The resulted showed there were 917 potential target genes of ALV-miRNA-p19-01 had been identified
Project description:In this study, we want to screen differentially expressed circRNAs in ALV-J-induced tumor chickens by circRNA-seq, and then conduct the mechanism research of those important circRNAs in ALV-J-induced tumor chickens
Project description:Avian leukosis virus (ALV) causes substantial economic losses from mortality and decreased performance in poultry industry. To characterize the response to ALV challenge, we developed a novel methodology that combines four datasets: mRNA expression and their associated regulatory factors of miRNA and lncRNA, and ALV gene expression. Specific Pathogen-Free (SPF) layer chickens were assigned to the ALV-infected or control group. Spleen samples (n=6) were collected at 40 days post injection (dpi), and sequenced. Comparing the infected and non-infected groups, 864 genes, 7 miRNAs and 17 lncRNAs were differentially expressed.
