Identification of the immune enhancement effect of CpG ODN on periodontitis genetic vaccine by RNA sequencing

Project description:Periodontitis is one of the main causes of tooth loss in adults. Early diagnosis and intervention can effectively control the progression of periodontitis. The research group constructed a periodontitis genetic vaccine in the early stage and improved the immunogenicity of the body by adding CpG oligonucleotide (CpG ODN). The purpose of this study was to analyse the potential mechanism by which CpG ODN adjuvants enhance the preventive effect of periodontitis genetic vaccines at the molecular level by transcriptome sequencing and to screen out key genes and signaling pathways for follow-up research.

An integrated transcriptomics and metabolomics study of the immune response of newly hatched chicks to the CpG-ODN stimulation

Project description:This study aims at identifying a dual transcriptomics and metabolomics blood signature following administration of CpG-ODN (cytosine-phosphate-guanine oligodeoxynucleotides), a reference immune-stimulatory molecule. A clinical study was conducted with chicks and transcriptomics and metabolomics analyses were performed on whole-blood and plasma samples respectively. Statistical analyses resulting in lists of differentially expressed genes and metabolites with different abundance were identified in chicks treated with CpG-ODN. The results showed that CpG-ODN activates the innate immune systems within hours following administration and its effect lasts over time, as metabolomic and transcriptomic profiles are still varying at 6 days after administration.

Gene expression profile of IGROV1 cells after in vitro treatment with CpG-ODN

Project description:CpG-ODN is a potent immuno-stimulatory molecule. In order to exclude a direct effect of murine CpG-ODN on IGROV1 human ovarian cancer cell line a gene expression experiment was performed. The ovarian cancer cell line IGROV-1 was obtained from the ATCC (Rockville, MD). Cells were routinely maintained in RPMI medium 1640 (Sigma, St. Louis, MO) supplemented with 10% FCS (Sigma) and 2 mM glutamine (Cambrex, East Rutherford, NJ). Cells were maintained at 37°C in a water-saturated atmosphere of 5% CO2 in air. 1x106 IGROV-1 cells were seeded in 6-well plates and, after seeding, cells were treated with 10uM of CpG-ODN in culture medium [phosphorothioated ODN1826 (5’-TCCATGACGTTCCTGACGTT-3’), TriLink Biotechnologies (San Diego, CA, USA)] for 24 hours. At the end of treatment, cells were collected and RNA extracted.

Identification of differentially expressed lncRNAs in CpG ODN-activated macrophage

Project description:The innate immune system is the first line of defense against microbial pathogens. The activated innate immune system plays important roles in eliciting antimicrobial defenses. Despite the benefits of innate immune responses, excessive inflammation will cause host damage. Thus, tight regulation of these processes is required for the maintenance of immune homeostasis. Recently, a new class of long non-coding RNAs (lncRNAs) has emerged as important regulators in many physiological and pathological processes. Dysregulated lncRNAs have been found to be associated with excessive or uncontrolled inflammation. In this study, we employed a lncRNA microarray-based profiling assay to detect changes of lncRNAs at different stages of CpG ODN-induced macrophage activation. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed based on the function of mRNAs. Co-expression and network potential targeting relationship were constructed according to the microarray results and bioinformatics predictions. Our findings revealed the involvement of lncRNAs in the process of CpG ODN-induced macrophage activation.

IGROV1 miRNA expression analysis after in vivo locoregional treatment with CpG-ODN

Project description:We reported that peri-tumoral CpG-ODN treatment, probably activating TLR9-expressing cells present in the tumor microenvironment, sensitized cancer cells to DNA-damaging chemotherapy (Cancer Res 2011 Oct 15;71(20):6382-90). Here, we investigated whether this treatment induces a modulation of miRNAs and their involvement in chemotherapy sensitivity. Twenty miRNAs were found differentially expressed in tumors from CpG-ODN-treated mice versus controls. Evaluation of the role of miR-424, miR-340 and miR-302b on cisplatin sensitivity revealed that ectopic expression of miR-302b (up-modulated in our array) in IGROV1 cells significantly improved cisplatin activity. The identification of miRNAs able to modify sensitivity to chemotherapy treatment will provide an experimental base for its future possible use as a target or tool of specific therapies. IGROV1 human ovarian carcinoma cells were adapted to growth intraperitoneally (i.p.) and maintained by serial i.p. passages of ascitic cells into healthy mice. Mice were injected i.p. with 2.5 x 10^6 ascitic cells in 0.2 ml of saline and treated starting 10-11 days later, when mice showed evident and established ascites, with CpG-ODN [phosphorothioated ODN1826 (5'-TCCATGACGTTCCTGACGTT-3')] delivered i.p. at a dose of 20 µg/mouse for 3 consecutive days, control mice received saline (4 mice/group). 24 hours after the last treatment, ascites-bearing mice were sacrificed. Tumor cells adherent to peritoneal wall were collected and immediately frozen in liquid nitrogen until RNA extraction.
