miR-34a in Neurophysiology and Neuropathology
Chua CEL, Tang BL.. Journal of molecular neuroscience : MN, 2018-11-28
Topic: Inflammation, microglia and astrocytes
Epigenetic influence of brain and neuronal function plays key regulatory roles in health and diseases. The microRNA miR-34a is a tumor suppressor transcript, and its loss has been prominently linked to various human cancers, including malignancies of the brain. Interestingly, miR-34a is abundantly expressed in the adult mammalian brain, and emerging evidence has implicated its involvement in a range of neurodevelopmental and neuropathological processes. Developmentally, miR-34a regulates neural stem/progenitor cell differentiation and aspects of neurogenesis. During aging, its elevation is connected to hearing loss and age-related macular degeneration. Pathologically, its elevations during epileptic seizures and ischemic stroke contribute to neuronal injury and death. Inhibition or suppression of miR-34a improved neuronal survival against a variety of neurotoxins implicated in Parkinson's disease. Its elevation may also play a role in neuronal demise in animal models of Alzheimer's disease, and suppression of its levels may be generally neuroprotective. The roles and activities of miR-34a in the brain are modulated by factors that control its expression (such as Tp53/73), as well as its downstream target genes (such as the sirtuins SIRT1 and SIRT6) and signaling pathways (such the Notch pathway). We discuss here the known and emerging roles of the miR-34a regulatory network in neurophysiology and neuropathology.

Study details
- Evidence strengthLow
How this study scored 38/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 22 of the 58 points we could judge it on, which is 38 out of 100.
