Project description:We conducted this study to determine whether exosome regulation underlies the antimigraine mechanisms of acupuncture. By comparing serum samples from patients with migraine and healthy controls using high-throughput small RNA sequencing technology , we identified 705 exosomal microRNAs that are differentially expressed in patients with migraine, and this set of 705 microRNAs included five that are particularly well characterised (hsa-miR-369-5p, hsa-miR-1268b, hsa-miR-145-5p, hsa-miR-222-5p, and hsa-miR-4488). By comparing serum samples collected from patients with migraine before and after acupuncture treatment, we showed that acupuncture normalised the expression levels of those five well-characterised exosomal microRNAs.

Project description:Background: Although many cardiovascular disease studies have focused on the characteristics of microRNAs in circulating exosomes, the profile and the potential clinical diagnostic value of plasma exosomal long RNAs (exoLRs) in acute myocardial infarction (AMI) is still unknown. Methods: In this study, exoLRs profile of 10 AMI patients, 8 stable coronary artery disease (CAD) patients, and 10 healthy individuals were achieved by exosomes isolation and RNA sequencing. Bioinformatics approaches were used to investigate the features and potential clinical value of exoLRs. Results: Exosomal messenger RNAs (mRNAs) made up a majority of the total exoLRs. Immune cell types analyzed by CIBERSORT showed that neutrophils and monocytes were significantly enriched in the AMI group which were consistent with the clinical baseline characteristic. The biological processes enrichment analyses of different exosomal mRNAs and co-expression network analysis both indicated that neutrophils activation associated processes were enriched in the AMI group. We further identified two exosomal mRNA ALPL and CXCR2 which might be served as potential biomarkers for AMI diagnosis. Conclusions: Our study explored the alteration of exoLRs in the AMI patients which was associated with the acute inflammatory response mediated by neutrophils. Exosomal mRNAs ALPL and CXCR2 might be potentially useful for AMI diagnosis.
Project description:Introduction: In our previous study, we demonstrated that acupuncture improved gait disturbances, such as hypometric gait, in patients with Parkinson’s disease (PD). To investigate specific genes that indicate a therapeutic response to acupuncture, we analyzed transcriptome alterations following acupuncture using blood samples collected in our previous clinical trial. Methods: We reanalyzed the clinical data of patients and selected a representative patient with PD for transcriptomic analysis following acupuncture. We examined the expression changes of PD biomarker genes known to be consistently dysregulated in both the brain and blood in patients with PD. We validated these gene expression changes using quantitative real-time polymerase chain reaction (qPCR) in the blood of five other patients with PD who received acupuncture treatment. Results: After acupuncture treatment, the transcriptomic alterations in the representative patient were similar to those induced by dopaminergic therapy. Among PD biomarkers, ankyrin repeat domain 22 (ANKRD22), which is upregulated after dopaminergic therapy, and synapsin 1 (SYN1), which is the common gene to indicate synaptic dysfunction in PD, were upregulated following acupuncture. These alterations correlated with changes of gait parameters in patients with PD.alterations following acupuncture using blood samples collected in our previous clinical trial. Conclusion: This is the first report on gene expression changes and improvement of gait disturbance in patients with PD following acupuncture. Our data suggest that ANKRD22 and SYN1 can be used as biomarkers for therapeutic response to acupuncture in patients with PD, especially those with gait disturbance.alterations following acupuncture using blood samples collected in our previous clinical trial.
