[Research progress on bidirectional effect of microRNA on Alzheimer's disease and intervention with traditional...

Area of Science:

• Neuroscience
• Genetics
• Pharmacology

Background:

• Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by memory loss, amyloid plaques, and neurofibrillary tangles.
• MicroRNAs (miRNAs) are small non-coding RNAs increasingly recognized for their role in regulating gene expression relevant to AD pathophysiology.
• Abnormal miRNA expression is a hallmark of AD, suggesting their involvement in disease development and progression.

Purpose of the Study:

• To elucidate the neuroprotective and neurotoxic effects of miRNAs in the context of Alzheimer's disease.
• To investigate traditional Chinese medicines (TCMs) capable of modulating miRNA expression for AD treatment.
• To establish a foundation for understanding the miRNA-AD pathogenesis relationship and guide the development of novel TCM-based anti-AD therapies.

Main Methods:

• Literature review of studies on miRNA function in Alzheimer's disease.
• Analysis of research on traditional Chinese medicines targeting miRNA pathways in AD.
• Synthesis of findings to connect miRNA dysregulation, AD pathology, and TCM interventions.

Main Results:

• MicroRNAs exhibit both beneficial and detrimental effects on neuronal function and survival in AD models.
• Specific miRNAs are dysregulated in AD patients, correlating with disease-related gene expression.
• Several TCMs demonstrate the ability to modulate aberrant miRNA levels implicated in AD.

Conclusions:

• MicroRNAs are critical players in Alzheimer's disease pathogenesis, offering potential therapeutic targets.
• Traditional Chinese medicines hold promise for regulating miRNA expression and mitigating AD progression.
• Further research into miRNA-TCM interactions can lead to innovative strategies for Alzheimer's disease treatment.
