Human circRNA expression profiling in plasma sample of hepatocellular carcinoma

Project description:Arraystar Human circRNA Microarray is designed for the global profiling of human circRNAs. In this study, we applied a circRNA microarray to screen the potential biomarker for HCC. 20 samples extracted from plasma samples including HCC group before operation, and after operation, CH group and control group. Each group contained five samples.

Effects of Electroacupuncture on the CircRNA of Plasma Exosomes in Diabetic Mice: Based on RNA Sequencing Technique

Project description:Aim: To study the effect of electroacupuncture (EA) on circRNA expression of plasma Exosomes and signal pathway of type 2 diabetic mice (T2DM). Methods: 10 mice were randomly selected as normal group. 20 mice were for T2DM model preparation and then were randomly divided into model and model + EA group. Mice in model + EA group were given EA treatment. The changes of fasting blood glucose (FBG) and the Islet structure were evaluated. Plasma exosomes of mice were subjected to RNA sequencing. Bioinformatics analysis on differentially expressed circRNA was performed. 12 differentially expressed circRNA were confirmed for real-time quantitative PCR (qPCR). Results: EA treatment reduced the FBG, preserved islets structure and reduced the islet β cell apoptotic rate of T2DM mice. RNA-sequencing analysis showed EA treatment lead to significant change of 165 circRNA expressions. GO and KEGG revealed that the effects of EA on T2DM mainly focus on regulating the functions and pathways related to multi-link metabolism, cell growth and organ development. Especially, the thyroid hormone signaling pathway was actively regulated by EA. circRNA/miRNA interactions analysis revealed that that mmu-mir-7092-3p was closely combined with circINPP4B, suggesting phosphatidylinositol signaling pathway was affected by EA. 12 circRNAs were identified to have significant differences by qRT-PCR. Conclusion: EA intervention can significantly protect islet function and improve FBG in T2DM, which may be related to the regulation on thyroid hormone and Phosphatidylinositol signaling pathway.

circRNA and lncRNA transcriptome of cancer tissues, adjacent normal tissues and plasma exosomes of patients with intrahepatic cholangiocarcinoma

Project description:Intrahepatic cholangiocarcinoma (ICC) is a liver tumor featured by challenges of non-invasive early diagnosis and a higher prevalence rate in Asian countries. These characteristics necessitate the development of liquid biopsy and immunotherapy methods to improve the prognosis of patients with ICC. Herein, we conducted a pilot study on the transcriptome of tumor tissues, adjacent normal tissues, and plasma exosomes of Asian patients with ICC from northern and southern China. We identified a subgroup of immunogenic Asian ICC, which is different from Caucasian ICC and is characterized by T cell exhaustion and neutrophil extracellular traps. The levels of circ-PTPN22 (hsa_circ_0110529) and circ-ADAMTS6 (hsa_circ_0072688), potential circRNA biomarkers, were elevated in the ICC tumor tissues and plasma exosomes of this subgroup than in the other subgroups and normal controls. These circRNAs were derived from post-transcriptional backsplicing of PTPN22 and ADAMTS6 that were expressed in T cells and endothelial cells, respectively, in the ICC microenvironment. Our results revealed a subgroup of Asian ICC characterized by T cell exhaustion and neutrophil extracellular traps and marked by elevated levels of circ-PTPN22 and circ-ADAMTS6 in tumor tissues and plasma exosomes. This subgroup is potentially detectable by plasma exosomal circRNAs and treatable with immune checkpoint blockade.

circRNA-sequencing analysis of plasma exosomes in hepatocellular carcinoma

Project description:Hepatocellular carcinoma (HCC) is currently the third leading cause of death worldwide and the most common type of primary liver cancer, finding noninvasive biomarkers for HCC diagnostic and prognostic are very urging. Previous genomic studies mainly focus on finding miRNA biomarkers for HCC. In this study, we focus on finding circRNA fragments suitable for serving as hcc biomarkers with plasma exosomal RNA-seq..

circRNA expression in cutaneous squamous cell carcinoma (cSCC)

Project description:Punch biopsies from patients with cSCC (n=3) and non-lesional skin (n=3) were included in the study. Microarray based circRNA expression profiles were acquired using Arraystar circRNA Arrays V. 2.0 screening for 13.617 distinct human circRNA candidates. We identified circRNAs differentially expressed in cSCC compared to non-lesional skin (control).
