Project description:Purpose: The goals of this study are to describe the RNA contents in apoptotic bodies (ABs) derived from osteoclasts at different stages and to compare the differences among those ABs from difference cell stages. The biological function of these ABs are also predicted and evaluated. Methods: Primary bone marrow cells were isolated and treated with M-CSF (30ng/mL) to generate bone marrow macrophages (BMMs). BMMs were then used to generate preosteoclast (pOC) stimulated by M-CSF (30ng/mL) together with RANKL (100ng/mL) for 24 h and mature osteoclast (mOC) stimulated by M-CSF (30ng/mL) together with RANKL (100ng/mL) for 72 h or more. RNA profiles of BMM, pOC and mOC were generated by deep sequencing, using Illumina NovaSeq 6000. Results: After acquiring of clean reads, we used Hisat2 for spliced mapping. We mapped about 40 million sequence reads per sample to the mouse genome (GRCm38). Saturation rate analysis was then performed evaluating the gene coverage rate along with read depth increase. The transcripts mapping to difference functional region of the genome was then analyzed. Circos software was used to map the consistency of samples with mouse genome on a chromosomal level. The quantification of transcript intensity was analyzed using Fragments Per Kilobase of exon modelper Million mapped fragments (FPKM). Conclusions: Our study represents the first high-throughput deep RAN sequencing data of cell derived apoptotic bodies. The biological prediction and analysis also revealed that ABs derived from osteoclast of different stages have distinct biological role. Followed by low throughput validation and detailed experiments, we identified that pOC derived ABs are more pro-angiogenic while mOC derived ABs are more pro-osteogenic.

Project description:We have been interested whether peripheral tolerance can be restored by vaccination with antigen-presenting cells (APCs) loaded with apoptotic bodies. Dendritic cells (DCs) are powerful APCs that have a critical role in the initiation and progression of autoimmunity. We previously demonstrated that DCs loaded with apoptotic islet cells prevents experimental type 1 diabetes (T1D), an autoimmune disease caused by beta-cell destruction. The goal of this study is to characterize the molecular changes on gene expression -transcriptome- occurring in these DCs pulsed with apoptotic bodies. Cells from four different genetically identical NOD (Non-Obese Diabetic) mice were used to obtain DCs. DCs were loaded with apoptotic bodies from NIT-1 cell line (insulinoma from NOD mice). Unloaded DCs were used as control in four paired experiments. Moreover, transcriptome from NIT-1 apoptotic bodies was determined. Mouse Gene 1.0 ST Arrays from Affymetrix (28,853 genes) were hybridized and genes with a p-value <= 0.002, adjusted p-value <= 0.08 and fold change (FC) >= 1.38 were considered upregulated, and genes with FC <= -1.37 were considered downregulated. Results demonstrate that apoptotic cells engulfment promotes molecular changes in DCs towards tolerogenic features. Gene expression profile of DCs from NOD mice that captured NIT-1 apoptotic bodies showed a downregulation of genes involved in antigen presentation and differential expression of cytokine, chemokine, natural immunity and immunoregulation genes together with the presence of specific transcripts for islet autoantigens. Molecular changes of DCs caused by the uptake of apoptotic bodies are key factors to induce antigen-specific peripheral tolerance.

Project description:Maintaining the homeostasis of immune ecological niches such as macrophages is essential for skin regeneration. In this study, apoptotic bodies (ABs) with intact bioactive substances of ADSC were constructed by biosynthesis. Further, injectable apoptotic bodies-GelMA microspheres (ABs@GMS) were constructed by microfluidics to maintain the homeostasis of the immune ecological niche in trauma, and inhibit the secretion of argininosuccinate synthetase 1 (ASS1) by ABs-induced downregulated JAK/STAT1 signaling pathway. Consequently, the macrophages’ polarization and inflammatory response were balanced in the wound with promoted angiogenesis. This ABs-functionalized microsphere slowly released biosynthetic apoptotic vesicles that expressed C1q, C3b and other surface "eat me" signals. These vesicles can be directly recognized, phagocytosed and degraded by macrophages, and allow scavenger cells to give meaning to cell death. In vitro, ABs@GMS balanced the JAK/STAT signaling pathway in a form of positive communication from dead to living cells via apoptotic vesicles. In vivo, ABs@GMS balanced the polarization of macrophages and increased the expression of α-smooth muscle actin. In conclusion, ABs synthesized by ADSC can balance traumatic immune disorders and restore homeostasis of the wound immune microenvironment, which would be a highly promising material for macrophage-mediated wound repair.

Project description:The number of patients with diabetes is increasing worldwide. Diabetic testicular damage can cause spermiogenesis disorders and sexual dysfunction. We thus explored the role of circRNA, lncRNA and mRNA in diabetic testicular damage, and revealed that they could serve as effective prevention and treatment therapeutic targets. Streptozotocin (STZ) was used to generate a rat model of type 2 diabetes. Rat testicular tissues were used for circRNA, lncRNA and mRNA sequencing.

Project description:Statins are competitive inhibitors of (3-hydroxy-3-methylglutaryl coenzyme A) HMG-CoA reductase. The primary mechanism of statins is the lowering of serum cholesterol through inhibiting hepatic cholesterol biosynthesis. Statins exert pleiotropic vasoprotective and atheroprotective effects in the vasculature, with its mechanism of action being incompletely understood.To depict the statin-regulated mRNA,long non-coding RNA (lncRNA) and circular RNA (circRNA) in human endothelial cells, we performed transcriptomic profiling of human umbilical vein endothelial cells (HUVECs) with atorvastatin treatment.Differentially expressed mRNA, lncRNA and circRNA may represent novel therapeutic targets against cardiovascular diseases.

Project description:Apoptosis plays a pivotal role in embryogenesis and postnatal cell homeostasis, involving DNA or subcellular fragmentation, and shedding of small membranous microvesicles termed apoptotic bodies (AB). Following DNA damage, hypoxia, or vascular injury, the chemokine CXCL12 has been implicated in the recruitment of progenitor cells for tissue regeneration through its receptor CXCR4 and in mechanisms counteracting apoptosis. Whether AB deliver alarm signals for regenerative responses to neighbouring cells beyond recruitment or eat-me signals for phagocytes and relevance to diseases with abundant apoptosis, eg atherosclerosis, remains unknown. Here we show that endothelial cell-derived AB are generated during diet-induced atherosclerosis and can be transferred to recipient endothelial or smooth muscle cells to induce functional expression of CXCL12. This is mediated through miRNA-126 enriched in AB, which acts by silencing RGS16 translation and unlocking CXCR4 to unleash an auto-regulatory feedback loop inducing CXCL12. Injection of AB promoted mobilization and incorporation of progenitor cells, reducing diet-induced atherosclerosis in apolipoprotein E-deficient mice, and local transfer of microRNA-126 inhibited collar-induced arterial plaque formation. This was associated with increased smooth muscle content but decreased macrophage and apoptotic cell content, all features of plaque stability. Our data identify a new mechanism, by which AB confer microRNA-126 as a paracrine alarm messenger to enhance CXCR4 signals and CXCL12 expression, thereby limiting or repairing vascular damage. This adds to the important functions of microRNAs in health and disease and may extend to progenitor cell recruitment during other forms of tissue repair or homeostasis. AB were isolated from supernatants of apoptotic, serum-starved human umbilical vein endothelial cells (HUVECs) by sequential centrifugation steps. Total RNA was isolated from AB or HUVECs and microRNA was purified using the mirVanaTM miRNA Isolation Kit (Ambion). microRNA obtained from 10 µg of total RNA was labeled using the mirVanaTM miRNA Labeling Kit (Ambion) and fluorescent Cy3 (Molecular Probes), and hybridized to the Ambion mirVanaTM miRNA Bioarray (1566 v.1). Hybridized mirVana miRNA Bioarrays were scanned and quantified by using ImaGene 5.5.4 (Bio Discovery). Resulted signal intensities were background corrected and then normalized using variance stabilization normalization. (Huber, 2002).
