microRNA-425 loss mediates amyloid plaque microenvironment heterogeneity and promotes neurodegenerative pathologies.

Different cellular and molecular changes underlie the pathogenesis of Alzheimer's disease (AD). Among these, neuron-specific dysregulation is a necessary event for accumulation of classic pathologies including amyloid plaques. Here, we show that AD-associated pathophysiology including neuronal cell death, inflammatory signaling, and endolysosomal dysfunction is spatially colocalized to amyloid plaques in regions with abnormal microRNA-425 (miR-425) levels and this change leads to focal brain microenvironment heterogeneity, that is, an amyloid plaque-associated microenvironment (APAM).

miR-425 deficiency promotes necroptosis and dopaminergic neurodegeneration in Parkinson's disease.

A major hallmark of Parkinson's disease (PD) is the degeneration of dopaminergic neurons in the substantia nigra, and the causative mechanism is thought to be the activation of programmed neuronal death. Necroptosis is a regulated process of cell death triggered by RIPK1. Although the pathophysiology of PD has been studied extensively, the cellular mechanism underlying dopaminergic neuron death remains unclear.

Rho-associated coiled-coil kinase 1 activation mediates amyloid precursor protein site-specific Ser655 phosphorylation and triggers amyloid pathology.

Rho-associated coiled-coil kinase 1 (ROCK1) is proposed to be implicated in Aβ suppression; however, the role for ROCK1 in amyloidogenic metabolism of amyloid precursor protein (APP) to produce Aβ was unknown. In the present study, we showed that ROCK1 kinase activity and its APP binding were enhanced in AD brain, resulting in increased β-secretase cleavage of APP. Furthermore, we firstly confirmed that APP served as a substrate for ROCK1 and its major phosphorylation site was located at Ser655.

The association between body lead levels and childhood rickets: A meta-analysis based on Chinese cohort.

Echogenic alteration in the raphe nuclei measured by transcranial sonography in patients with Parkinson disease and depression.

Background: Recently, several studies using transcranial sonography (TCS) have demonstrated reduced echogenicity of the mesencephalic midline in unipolar depression and patients with comorbid depression and Parkinson disease (PD). However, there is no consensus on the conclusion that raphe nuclei (RN) hypoechogenicity is associated with depression in PD. The methods used in previous studies lack quantitative and objective indicators to some extent; therefore, the present study used the level of platelet 5-hydroxytryptamine (5-HT) as an objective indicator of depression.

Numerical study on the lubrication performance of compression ring-cylinder liner system with spherical dimples.

The effects of surface texture on the lubrication performance of a compression ring-cylinder liner system are studied in this paper. By considering the surface roughness of the compression ring and cylinder liner, a mixed lubrication model is presented to investigate the tribological behaviors of a barrel-shaped compression ring-cylinder liner system with spherical dimples on the liner. In order to determine the rupture and reformulation positions of fluid film accurately, the Jacoboson-Floberg-Olsson (JFO) cavitation boundary condition is applied to the mixed lubrication model for ensuring the mass-conservative law.

The development prospection of HDAC inhibitors as a potential therapeutic direction in Alzheimer's disease.

Alzheimer's disease (AD) is a chronic neurodegenerative disease, which is associated with learning and memory impairment in the elderly. Recent studies have found that treating AD in the way of chromatin remodeling via histone acetylation is a promising therapeutic regimen. In a number of recent studies, inhibitors of histone deacetylase (HDACs) have been found to be a novel promising therapeutic agents for neurological disorders, particularly for AD and other neurodegenerative diseases.

ROCK1 Is Associated with Alzheimer's Disease-Specific Plaques, as well as Enhances Autophagosome Formation But not Autophagic Aβ Clearance.

Alzheimer's disease (AD) is the most prevalent form of late-life dementia in the population, characterized by amyloid plaque formation and increased tau deposition, which is modulated by Rho-associated coiled-coil kinase 1 (ROCK1). In this study, we further analyze whether ROCK1 regulates the metabolism of amyloid precursor protein (APP). We show that ROCK1 is colocalized with mature amyloid-β (Aβ) plaques in patients with AD, in that ROCK1 enhances the amyloidogenic pathway, and that ROCK1 mediated autophagy enhances the intracellular buildup of Aβ in a cell model of AD (confirmed by increased ROCK1 and decreased Beclin 1 protein levels, with neuronal autophagosome accumulation in prefrontal cortex of AD APP/PS1 mouse model).

MicroRNA-146a represses LRP2 translation and leads to cell apoptosis in Alzheimer's disease.

MicroRNA regulation of transcript expression has been reported in patients with Alzheimer's disease (AD). Here, we investigate the role of microRNA-146a (miRNA-146a), a brain-enriched miRNA, which is upregulated in AD patients. Through analysis of predicted targets of miRNA-146a, low-density lipoprotein receptor-related protein-2 (Lrp2), a member of the LDLR family that is known to play a protective role in AD, was identified.

MicroRNA-146a suppresses ROCK1 allowing hyperphosphorylation of tau in Alzheimer's disease.

MicroRNA-146a is upregulated in the brains of patients with Alzheimer's disease (AD). Here, we show that the rho-associated, coiled-coil containing protein kinase 1 (ROCK1) is a target of microRNA-146a in neural cells. Knockdown of ROCK1 mimicked the effects of microRNA-146a overexpression and induced abnormal tau phosphorylation, which was associated with inhibition of phosphorylation of the phosphatase and tensin homolog (PTEN).

Peripheral Blood MicroRNA Expression Profiles in Alzheimer's Disease: Screening, Validation, Association with Clinical Phenotype and Implications for Molecular Mechanism.

A series of investigations have been performed regarding microRNA (miRNA, miR) of Alzheimer's disease (AD) patients. However, most of these used microarray with neither validation by PCR nor any follow-up on the biological mechanism implicated by findings. Further, there were rarely any analyses linking clinical phenotype of de novo, drug-naive patients to cellular pathogenic mechanism(s) to date.
