Context: Neurodegenerative diseases (NDs) are neurological disorders characterized by the degeneration of the central nervous system (CNS). Studies have examined interactions between long non-coding RNAs (lncRNAs) and functioning of the CNS in NDs. In this study, we summarized the role of different lncRNAs in most NDs. Methods: In this study, different papers published between years 2003 and 2020 were reviewed. Results: LncRNAs can play a significant role in the development of brain disorders. Conclusions: The dysregulation of lncRNAs has been shown to affect NDs such as Alzheimer's disease (AD) and Parkinson’s diseases (PD). In this review, we compiled recent findings related to the main lncRNAs associated with brain disorders.
The impact of peripheral nerve damage on a patient's quality of life is severe. The most frequent peripheral nerve crush damage is a sciatic nerve injury. Previous research has shown that glibenclamide (GB) has neuroprotective properties in a variety of oxidative stress‐related disorders, including Alzheimer and Parkinson. The goal of this study was to see how GB affected nerve regeneration and improved function of the sciatic nerve in a rat model following a crush injury. We evaluated motor function, sensory recovery, gene expression, and histomorphometry following damage at different time points. Additionally, we assessed atrophy in the gastrocnemius muscle using histology and mass ratio analyses. Our results suggest that 2, 4, 6, and 8 weeks following glibenclamide therapy, promotes the recovery of motor and sensory function in the injured site. Following glibenclamid injection, the mRNA levels of neurotrophic factors (NGF and BDNF) are raised. According to histomorphometry assessment, glibenclamide injection also increased the number of myelinated fibers while decreasing their thickness. These results showed that glibenclamide therapy by decreasing the proinflammatory and oxidant factors may enhance the nerve regeneration. It is clear that more research is needed to confirm these findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
