The Potential Mechanism of Hippo Signaling Pathway and Its Related miRNA Intervention in Alzheimer's Disease and Parkinson's Disease
The main characteristics of neurodegenerative diseases represented by Alzheimer's disease(AD)and Parkinson's disease(PD)is the progressive irreversible loss of neurons,leading to varying degrees of pathological changes and loss of cognitive function.There is still no effective treatment.With the acceleration of global aging society,the incidence of neurodegenerative diseases is rapidly increasing,becoming a serious global public health concern that urgently requires the development of effective therapeutic strategies.The Hippo signaling pathway,a highly evolutionarily conserved pathway,consists of the core components MST1/2,LATS1/2,and downstream effectors,transcriptional co-activators YAP and TAZ.It plays a crucial role in the regulation of various biological processes such as cell proliferation,differentiation,development,and apoptosis.Dysregulation of the Hippo pathway contributes to the development of many diseases,including cancer,cardiovascular diseases,immune disorders,etc.Therefore,targeting the dysregulated components of the Hippo pathway may be an effective strategy for treating various diseases.Increasing evidence indicates that the Hippo pathway is excessively activated in the development of neurodegenerative diseases,manifested by increased expression of MST1 and downregulation of YAP.Stabilizing the Hippo pathway levels has shown improvements in AD and PD.However,most studies on the Hippo pathway in AD and PD focus on changes in the expression levels of Hippo pathway components,and research in other neurodegenerative diseases is still lacking.Therefore,further investigation is needed to fully understand the mechanistic role of the Hippo pathway in neurodegenerative diseases.Meanwhile,miRNA,similarly dysregulated in neurodegenerative diseases and serving as biomarkers,is a primary target for miRNA therapy in neurodegenerative diseases,including AD and PD.Activating or inhibiting dysregulated miRNAs is the main strategy of miRNA therapy during the neurodegenerative disease development.Evidence suggests that the interaction between the Hippo pathway and miRNA can result in widespread biological effects and crosstalk in the occurrence of different types of diseases.However,studies on the interplay between the Hippo pathway and miRNA in neurodegenerative diseases are relatively scarce.In this paper,we predicted the miRNAs related to Hippo pathway through bioinformatics database,and further screened the miRNAs with crosstalk relationship with Hippo signaling pathway through experiments in combination with PubMed.Then,the mechanism of action of Hippo signaling pathway related miRNAs in AD and PD is further elucidated.It is reported that the Hippo pathway and its related miRNA may exert neuroprotective effects by reducing oxidative stress,improving neuroinflammation,stabilizing autophagy levels,maintaining neuronal mitochondrial function,and ameliorating blood-brain barrier dysfunction,thereby delaying the progression of AD and PD.However,research on miRNA directly regulating the Hippo pathway to improve AD and PD is limited,and observations of the Hippo pathway and its related miRNA in other neurodegenerative diseases are scarce.However,considering the regulatory relationship between the Hippo pathway and miRNA in multiple diseases and their respective roles in key mechanisms of neurodegenerative diseases,such as oxidative stress and neuroinflammation,the crosstalk between miRNA and the Hippo pathway holds a crucial regulatory role in the development of neurodegenerative diseases.Thus,the interaction pathways of the Hippo pathway and its related miRNA may be a pivotal avenue for exploring effective therapeutic strategies for neurodegenerative diseases in the future.
