Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?
MIR133B is a microRNA implicated in various biological processes and has been observed to interact with other RNA molecules and to play a role in disease contexts [PMC7068214]. Specifically, lncRNA LOC400043 has been found to interact with MIR133B, leading to the downregulation of its expression [PMC7068214]. This microRNA has also been utilized in research as a means to attenuate infection by inserting its target sites into the genome of the influenza A virus, demonstrating effective attenuation in murine myocyte-like cells and cardiac tissue [PMC9094651]. Beyond its application in virology, MIR133B has been profiled by researchers studying Parkinson's disease (PD), indicating its potential relevance in the pathology of neurodegenerative diseases [PMC3540391]. The therapeutic potential of MIR133B has been explored through intranasal (IN) delivery, which was assessed for its impact on functional recovery post-spinal cord injury (SCI) using two behavioral tasks: GSM for forelimb grip strength evaluation and a hanging task for forelimb grasp assessment during an 8-week testing time post-SCI [PMC10047048].
