Schizophrenia-Associated MIR204 Regulates Noncoding RNAs and Affects Neurotransmitter and Ion Channel Gene Sets

چکیده
As regulators of gene expression, microRNAs (miRNAs) are likely to play an important role in the development of disease. In this study we present a large-scale strategy to identify miRNAs with a role in the regulation of neuronal processes. Thereby we found variant rs7861254 located near the MIR204 gene to be significantly associated with schizophrenia. This variant resulted in reduced expression of miR-204 in neuronal-like SH-SY5Y cells. Analysis of the consequences of the altered miR-204 expression on the transcriptome of these cells uncovered a new mode of action for miR-204, being the regulation of noncoding RNAs (ncRNAs), including several miRNAs, such as MIR296. Furthermore, pathway analysis showed downstream effects of miR-204 on neurotransmitter and ion channel related gene sets, potentially mediated by miRNAs regulated through miR-204.

Hepatitis C virus core impacts expression of miR122 and miR204 involved in carcinogenic progression via regulation of TGFBRAP1 and HOTTIP expression
Background Despite the breadth of understanding the noncoding RNAs' function in molecular biology, their functional roles in hepatocellular carcinoma (HCC) is poorly understood. In this study, we investigated the effect of hepatitis C virus (HCV) core upon the expression of noncoding RNAs. Methods The lncRNAs, mRNAs, and circRNAs were employed for identification of HCV core protein gene expre...
متن کاملAssociation of Candidate Single Nucleotide Polymorphisms Related to Candidate Genes in Patients With Schizophrenia
Introduction: Schizophrenia is a chronic heterogenic neurodevelopment disorder. Many genes interfere in the development of SCZ. All four genes, NrCAM, PRODH, ANK3, and ANKK1, which were evaluated in this study, were previously reported to be associated with Schizophrenia. The NrCAM contributes to creating cognitive deficiencies through the CAM’s signaling pathway. PRODH plays a vital role in cr...
متن کاملThe TRPM7 Ion Channel Functions in Cholinergic Synaptic Vesicles and Affects Transmitter Release
A longstanding hypothesis is that ion channels are present in the membranes of synaptic vesicles and might affect neurotransmitter release. Here we demonstrate that TRPM7, a member of the transient receptor potential (TRP) ion channel family, resides in the membrane of synaptic vesicles of sympathetic neurons, forms molecular complexes with the synaptic vesicle proteins synapsin I and synaptota...

Background: MicroRNAs are small noncoding RNAs that regulate gene expression and involve in many cellular and physiological mechanisems. Recent studies have revealed that dysregulation of microRNAs might contribute to autoimmune disorders such as multiple sclerosis. Based on these findings, we examined the potential role of miR-320 isoforms, miR-320-3p and miR-320-5p, in the context of autoimmu...
متن کاملStudy of Long Noncoding RNA FER1L4 and RB1, as Its Competing Endogenous RNA Network Target Gene, in Breast Cancer
Introduction: Breast cancer is the second most common cause of cancer-related death among females, which requires an exploration for markers to propose a more specific categorization of this cancer. Long noncoding RNAs (lncRNAs), the main subset of noncoding transcripts, are involved in tumorigenic processes. In this study, we investigated the expression of the fer-1–like family member 4 (FER...
