Whole blood transcriptome profile identifies motor neurone disease (MND) RNA biomarker signatures

ABSTRACT: (1) Background: Blood-based biomarkers for motor neuron disease are needed for better di-agnosis, progression prediction, and clinical trial monitoring. We used whole blood-derived total RNA and performed whole transcriptome analysis to compare the gene expression pro-files in (motor neurone disease) MND patients to the control subjects. (2) Methods: We com-pared 42 MND patients to 42 aged and sex-matched healthy controls and described the whole transcriptome profile characteristic for MND. In addition to the formal differential analysis, we performed functional annotation of the genomics data and identified the molecular path-ways that are differentially regulated in MND patients. (3) Results: We identified 12,972 genes differentially expressed in the blood of MND patients compared to age and sex-matched con-trols. Functional genomic annotation identified activation of the pathways related to neuro-degeneration, RNA transcription, RNA splicing and extracellular matrix reorganisation. (4) Conclusions: Blood-based whole transcriptomic analysis can reliably differentiate MND pa-tients from controls and can provide useful information for the clinical management of the disease and clinical trials.

Affymetrix 6.0 study of sporadic motor neuron disease patients and controls.

Project description:This data was divided into three experiment sets: 1. A somatic study of sporadic motor neuron disease (SMND) brain samples that were compared to the blood from the same individual, normal control brains and disease control brans (Parkinson Disease patients); 2. A twin study comparing blood and other tissue samples from twins that were discordant for MND, concordant for MND and control twins and 3. A trio study of blood samples MND patients compared to their unaffected parents. Study 1: 36 sporadic motor neuron disease brain (lateral frontal cortex, Brodmann area 46), 34 matched sporadic motor neuron disease blood, 26 control brain (lateral frontal cortex, Brodmann area 46), 9 Parkinson Disease brain (disease controls, lateral frontal cortex, Brodmann area 46). Study 2 and study 3: 52 twin or trio blood, 4 twin hair, 1 twin sperm. 2 replicate twin blood and 1 replicate trio blood repeated at a different time. External control blood from Coriell GM15510 and GM10851.

mRNAseq in SBMA and control iPSC-derived motor neurons

Project description:RNA sequence was performed using mRNAs of motor neurons derived from iPSCs of four patients of spinal bulbar muscular atrophy (SBMA) and four age- and sex- matched controls. The analysis was performed using purified motor neurons by flowcytometry and cell sorting based on the expression of HB9e438::Venus reporter gene (P4) or unpurified motor neurons (NT).

miRNA-seq analysis of pre-seroconverted samples from fourteen children at risk of type 1 diabetes and their gender-, HLA-, and age-matched controls

Project description:We generated genome-wide whole-blood miRNA profiles for the fourteen multiple autoantibody-positive cases and their sex, age, and HLA-risk matched controls, using the miRNA-sequencing approach. Two samples just before the seroconversion from the fourteen case-control pairs were studied. Eight of the 10 cases progressed to clinical disease. A persistently autoantibody-negative control child was matched for each case, based on the date and place of birth, age, sex, and HLA-DQB1 genotype. In all, 56 unique blood samples were processed for genome-wide miRNA transcriptome analysis.

Small RNA Sequencing of Sporadic Amyotrophic Lateral Sclerosis Cerebrospinal Fluid Reveals Differentially Expressed miRNAs Related to Neural and Glial Activity

Project description:Amyotrophic lateral sclerosis (ALS) is a clinical subtype of motor neurone disease (MND), a fatal neurodegenerative disease involving the loss of both the upper and lower motor neurones from the motor cortex, brainstem, and spinal cord. Identifying specific disease biomarkers would help to not only improve diagnostic delay but also to classify disease subtypes, monitor response to therapeutic drugs and track disease progression. miRNAs are small non-coding RNA responsible for regulating gene expression and ultimately protein expression and have been used as biomarkers for many cancers and neurodegenerative disorders. Investigating the detection of miRNAs in cerebrospinal fluid (CSF), the fluid that bathes the central nervous system (CNS) is a prime target for identifying potential biomarkers for ALS. This is the first study to investigate the expression of miRNAs in the CSF of ALS patients using small RNA sequencing. We detected differentially expressed miRNAs in the CSF of sporadic ALS (sALS) patients related to neural and glial activity. Additionally, miRNAs involved in glucose metabolism and the regulation of oxidative stress were also identified. Detecting the presence of potential CSF derived miRNA biomarkers in sALS could open up a whole new area of knowledge to help gain a better understanding of disease pathophysiology.

MiRNAs expression in peripheral blood monouclear cells from stable COPD and healthy adults

Project description:To explore which miRNAs were altered in COPD, we performed a microRNA microarray analysis of peripheral blood mononuclear cells from stable COPD patients (n=6) and healthy controls (n=6). Sex, age, BMI and history of cigarette smoke were matched between different groups. Blood samples were obtained from stable COPD patients(n=6) and healthy adults (n=6) from clinical trial (NCT02037828). The study was in compliance with the Declaration of Helsinki and was approved by Peking University Institutional Review Board Office.

Circular RNAs to predict clinical outcome after cardiac arrest

Project description:Background: Cardiac arrest (CA) represents the third leading cause of death worldwide. Among survivors, severe neurological sequelae are frequent but difficult to predict. Novel prognostic biomarkers would offer clinicians the possibility to deliver personalized healthcare. The potential of small circulating noncoding RNAs (microRNAs) to predict neurological outcome and survival after CA has been reported. Objective: This study aims to identify circulating circular RNAs (circRNAs) associated with clinical outcome after CA. Methods and Results: Methods and Results: Whole blood samples obtained 48h after return of spontaneous circulation from 23 sex-matched survivors and 23 deceased cardiac arrest (CA) patients were enrolled in this study. Whole transcriptome RNA sequencing identified candidate RNAs associated with neurological outcome and survival. Conclusion: We have identified candidate RNAs associated with clinical outcome after CA whose predictive value remains to be confirmed in large populations.
