Development of gene expression signatures for chicken LMH cells infected with infectious laryngotracheitis virus (ILTV)

ABSTRACT: To explore the molecular events in LMH cells upon infectious laryngotracheitis virus (ILTV) infection, transcriptional profiling of LMH cells infected with ILTV was compared with uninfected control cells. Gene expression in LMH cells with or without virus infection was measured at two day post infection. Four independent experiments were performed.

<h4>Unlabelled</h4>Given the side effects of vaccination against infectious laryngotracheitis (ILT), novel strategies for ILT control and therapy are urgently needed. The modulation of host-virus interactions is a promising strategy to combat the virus; however, the interactions between the host and avian ILT herpesvirus (ILTV) are unclear. Using genome-wide transcriptome studies in combination with a bioinformatic analysis, we identified proto-oncogene tyrosine-protein kinase Src (Src) to be an ...[more]

Project description:Polymorphisms in pre-miRNAs may affect its expression, then having effect on its target mRNAs and be associated with cancer susceptibility. In the current study, we evaluated the association of a 3-base pair (3-bp) indel polymorphism (rs57408770) in pre-miR-3131 with hepatocellular carcinoma (HCC) susceptibility in a Chinese population. Logistic regression analysis showed that the insertion allele of rs57408770 was significantly associated with an increased risk for HCC occurrence in both case-control studies. To further investigated the molecular mechanism underlying the correlation between rs57408770 and the risk of HCC, overexpression of pre-miR-3131 in HCC cell line was performed. Human HCC cell lines Sk-Hep-1 was obtained from Shanghai Cell Bank of Chinese Academy of Sciences on 9 December 2013.The fragment of 366bp including the insert allele of rs57408770 in pre-miR-3131 was directly synthesized and cloned into BamHI and EcoRI sites of pEGFP-N1 yielding the wild-type vector (pEGFP-N1-miR3131-WT). The mutant-type vector (pEGFP-N1-miR3131-MT) including the delete allele of rs57408770 was generated using QuikChange Lightening Site-Directed Mutagenesis Kit. The resulting constructs were verified by direct sequencing. For overexpression experiments, cells were cultured in 6-well plates at a density of 200 000 cells per well the day before transfection. 2.5Î¼g plasmids of empty vector pEGFP-N1, pEGFP-N1-miR3131-WT or pEGFP-N1-miR3131-MT were transfected into the growing cells (about 80%-90% confluent) using Lipofectamine2000. After 24 hours of the transfection, the cells were collected for subsequent experiments.And human genome-wide gene expression profile assay was used to screen the targets of miR-3131. For overexpression experiments, cells were cultured in 6-well plates at a density of 200 000 cells per well the day before transfection. 2.5Î¼g plasmids of empty vector pEGFP-N1, pEGFP-N1-miR3131-WT or pEGFP-N1-miR3131-MT were transfected into the growing cells (about 80%-90% confluent) using Lipofectamine2000 (Invitrogen). After 24 hours of the transfection, the cells were collected for subsequent experiments. There are 3 samples in this experiment.
