Circulating microRNAs as potential biomarkers for psychiatric and neurodegenerative disorders

Publication date: Available online 7 December 2019Source: Progress in NeurobiologyAuthor(s): M.M.J. van den Berg, J. Krauskopf, J.G. Ramaekers, J.C.S. Kleinjans, J. Prickaerts, J.J. BriedéAbstractCirculating microRNAs (cimiRNAs) are a class of non-encoding RNAs found in bodily fluids such as blood, cerebrospinal fluid (CSF) and tears. CimiRNAs have been implicated as promising biomarkers for central nervous system (CNS) disorders because they are actively secreted as messengers and are profoundly involved in fine-tuning of developmental and differentiation processes. Furthermore, they are attractive biomarkers because they are extremely stable, tissue enriched and can be determined in a quantitative manner. This review aims to provide a comprehensive assessment on the current progress regarding the potential value of cimiRNAs as CNS biomarkers. Within this framework five CNS disorders are explored which share a common pathological hallmark namely cognitive impairment. The CNS disorders include Major depression disorder (MDD), Bipolar disorder (BD), Schizophrenia (SZ), Alzheimer’s disease (AD) and Parkinson disease (PD). The similarities and differences between altered cimiRNAs in the different disorders are described. The miR-29 family, miR-34a-5p and miR-132-3p are discussed as common dysregulated cimiRNAs found in the CNS disorders. Furthermore, it is shown that the type of bodily fluid used for measuring cimiRNAs is important as inconsistencies in cimiRNAs exp...

Authors: Beszłej JA, Wieczorek T, Kobyłko A, Piotrowski P, Siwicki D, Weiser A, Fila-Witecka K, Rymaszewska J, Tabakow P Abstract Deep brain stimulation (DBS) is a treatment method that is currently getting more and more attention from psychiatrists. It has proven to be efficacious and safe in the treatment of neurological disorders, mainly Parkinson's disease (PD), dystonia and essential tremor. DBS has very often contributed to successful treatment in cases that had proved resistant to all other methods of treatment. Nowadays treatment-resistant obsessive-compulsive disorder (OCD) is the main psychiatric indica...

What exactly is psychosis? What happens in the brain of a person with schizophrenia who is hallucinating? Schizophrenic Rachel Star Withers shares her personal hallucinations and delusions and Dr. Joseph Goldberg, who specializes in researching what goes on in the brain when someone is experiencing psychosis, joins to break down how the brain functions during psychotic episodes. Host Rachel Star Withers, a diagnosed schizophrenic, and co-host Gabe Howard delve into these intense subjects in this episode of Inside Schizophrenia.  Highlights from “Psychosis in Schizophrenia” Episode [02:13]  Rachel, do...

Preoperative and postoperative mental health status (MHS) of total joint arthroplasty patients can affect immediate and long-term outcomes following surgery. Alterations in MHS can be acute or chronic. The most common etiologies include acute changes due to (1) delirium or stroke, (2) movement disorders (Alzheimer dementia, Parkinson disease, multiple sclerosis, epilepsy), and (3) mood/behavior disorders (major depressive disorder, anxiety, bipolar disorder, schizophrenia). Across etiologies, alterations in MHS are associated with worse clinical/patient-reported outcomes and greater total cost of care. Prevention via pharm...

In this episode, Gabe talks with PsychCentral.com editor-in-chief Dr. John Grohol about the importance of planning for the end of life.  We all know that everybody dies, but at the same time, no one wants to think about their own inevitable death. Do you know how you would like the end of your life to go?  What if you needed to make that decision for a loved one? Do you know what they want? Would they want to be resuscitated? Do they want to die at home or in a hospital? Do you even know what kinds of decisions need to be made, or what the options are?  Listen in as Dr. John explains that there is a degre...

Abstract Dopaminergic (DA) neurons are involved in many critical functions within the central nervous system (CNS), and dopamine neurotransmission impairment underlies a wide range of disorders from motor control deficiencies, such as Parkinson's disease (PD), to psychiatric disorders, such as alcoholism, drug addictions, bipolar disorders, schizophrenia and depression. Neural stem cell-based technology has potential to play an important role in developing efficacious biological and small molecule therapeutic products for disorders with dopamine dysregulation. Various methods of differentiating DA neuron...

We reported DEGs with a nominal p-value of 0.8. The network construction was created using blockwiseModules function for consideration of computer efficiency. The module detection criteria were as follows: minimum module size of 50, deepsplit of 4, and merge threshold of 0.25. The merged modules were then summarized with module eigengene (ME) correlations>0.75. MEs were defined by their first principal component and were labeled with different colors as module names in the Results section. After the modules were generated, we conducted different enrichment analysis to explore the functional interpretation of genes withi...

Conclusion Taken together, evidence from animal and human studies demonstrates that the brain detects levels of circulating nutrients and hormones and consequently organizes an outward response that contributes to the regulation of whole-body glucose homeostasis. However, there are major knowledge gaps about the exact nature of this response and its relative importance compared to peripheral processes. As we have seen, animal studies have provided an anatomical map of CNS glucose regulation and have identified important neurons and neural circuits involved. Additionally, the CNS sensing of key nutrients and hormones has b...

Conclusion: Genetic associations of diseases considerably vary across populations which necessitates health-related genotyping efforts especially for so far understudied populations. SOM portrayal represents novel promising methods in population genetic research with special strength in visualization-based comparison of SNP data. Introduction Non-communicable polygenic diseases such as cancers, neurodegeneration, cardiovascular, and metabolic disorders have become the most prevalent type worldwide and account for the majority of death events in developed and transition economy countries (Habib and Saha, 2010; Benzi...
