Circular RNA expression alteration in rats after traumatic spinal cord injury (SCI)

Project description:To determine whether the expression levels of circular RNAs were altered and lay a foundation for future work, we used high-throughput microarray analysis to screen circular RNAs expression patterns in the spinal cord of adult rats after traumatic spinal cord injury (SCI), finally to evaluate the potential rat models as a platform for the development of novel therapeutic targets for spinal cord injury in future clinical studies. Overall six rats at 3 days post-SCI in two groups were used to perform the microarray.

Circular RNAs expression profiles and potential key molecules incompletely transected spinal cord injury.

Project description:Circular RNA is implicated in numerous diseases and conditions, including traumatic injury to the central nervoussystem. However, we know little regarding their role in completely transected spinal cord injury (SCI). Our studyused high-throughput sequencing to analyze circular RNA expression in rats after experimental completetransection of spinal cord. We found differential expression in 400 circular RNAs after SCI, with 249 significantlyup-regulated and 151 significantly down-regulated. We then selected five circular RNAs for qRT-PCR validation,and the results were in agreement with RNA sequencing. Additionally, we predicted the function of circular RNAin SCI through GO and KEGG analyses, as well as the construction of circRNA/microRNA interaction networks.Furthermore, we identified circular RNA chr9:1829226-1834212 and mRNA Hdac11 as key molecules after SCI.In conclusion, this study is the first to characterize circular RNA function in rats after completely transected SCI,through identifying their differential expression. Our results provide insight into the mechanism and therapeutictargets of SCI.

Bioinformatic analysis of circular RNA expression profiles in a rat lumbosacral spinal root avulsion model.

Project description:Lumbosacral spinal root avulsion (LSRA) is a severe nerve injury that results in devastating dysfunction in the lower limb. Circular ribonucleic acids (circRNAs) have been reported to be implicated in a variety of diseases. However, the role of circRNAs in LSRA remains unclear. Here, we performed RNA sequencing (RNA-seq) to determine circRNA expression profiles in a rat LSRA model and further investigated their potential functions and the underlying mechanisms by bioinformatic analyses and in vitro experiments. In all, 1708 circRNAs were found to be differentially expressed in spinal cord tissues after LSRA (|fold change| ≥ 2 and p < 0.05), with 591 up-regulated 1117 down-regulated. Meanwhile, 2263 mRNAs were also indentified to be differentially expressed, of which 1471 were upregulated and 792 were downregulated. Eight randomly selected circRNAs and mRNA were successfully verified to be consistent the RNA-seq results by quantitative real-time polymerase chain reaction. Functional analyses based on gene ontology and Kyoto Encyclopedia of Genes and Genomes predicted the potential roles of differentially expressed circRNAs and mRNAs in LSRA, and circRNA/miRNA/mRNA interaction networks revealed that circRNA_7025, a down-regulated circRNA in LSRA, was targeted by two neuronal apoptosis-related miRNAs, rno-miR-1224 and rno-miR-326-5p. Further in vitro experiments revealed that circRNA_7025 protected against oxygen-glucose deprivation induced neuronal apoptosis via the circRNA_7025/miR-1224/miR-326-5p axis. In summary, our results revealed circRNA expression profiles and their potential functions in LSRA. These findings improve our understanding of the pathogenic mechanisms involved in LSRA and might enable us to identify new molecular targets for LSRA.

Circular non-coding RNA ANRIL modulates ribosomal RNA maturation and atherosclerosis in humans.

Project description:Circular RNAs (circRNAs) are broadly expressed in eukaryotic cells, but their role in human health and disease remains obscure. Here, we show that circular antisense non-coding RNA in the INK4 locus (circANRIL), which is transcribed at a locus of atherosclerotic cardiovascular disease on chromosome 9p21, confers athero-protection by controlling ribosomal RNA (rRNA) maturation and modulating pathways of atherogenesis. At the molecular level, circANRIL competes with precursor rRNA (pre-rRNA) for binding to pescadillo homolog 1 (PES1), an essential 60S-preribosomal assembly factor, thereby impairing exonuclease-mediated pre-rRNA processing and ribosome biogenesis. As a consequence, circANRIL induces nucleolar stress and p53 activation, resulting in the induction of apoptosis and inhibition of proliferation, which are key athero-protective cell functions within the arterial wall. Collectively, these findings identify circANRIL as a prototype of a circRNA regulating ribosome biogenesis and conferring athero-protection, thereby unveiling a therapeutic potential of certain circRNAs in human disease. Analysis of transcriptome-wide expression level in HEK293 cells with stable overexpression of circular ANRIL (n=3) compared to a vector control (n=3).

Bulk RNA-Seq of male and female lumbosacral dorsal root ganglia after VEGFA-instillation

Project description:This study examined transcriptomics in lumbosacral dorsal root ganglia that carries bladder afferent signals in a bladder-origin visceral pain animal model. C57BL6/J male and female mice underwent intravesical instillations of VEGF165, a mouse recombinant of VEGFA to induce visceral hypersensitivity. Saline-instilled male and female mice were used as controls. Across the four experimental groups, we found significant sex differences in the transcriptome profile in both saline-instilled animals and VEGF-induced signaling pathway changes in the lumbosacral sensory ganglia. These findings provide insight into potential molecular targets for alleviating visceral pain symptoms when considering sex as a biological variable.
