The application of artificial intelligence in diagnosis of Alzheimer's disease: a bibliometric analysis.

Alzheimer's disease (AD) is a neurodegenerative disorder that severely impacts cognitive function, posing significant physical and psychological burdens on patients and substantial economic challenges to families and society, particularly in aging populations where its prevalence is rising. Current diagnostic and therapeutic strategies, including pharmacological treatments and non-pharmacological interventions, exhibit considerable limitations in early diagnosis, etiological treatment, and disease management. This study aims to investigate the application of artificial intelligence (AI) in the early diagnosis and progression monitoring of AD through a bibliometric analysis of relevant literature.

The role of astrocytes in Alzheimer's disease: a bibliometric analysis.

Background: Alzheimer's disease (AD) is a neurodegenerative disorder marked by cognitive decline and memory loss. Recent research underscores the crucial role of astrocytes in AD. This study reviews research trends and contributions on astrocytes in AD from 2000 to 2024, shedding light on the evolving research landscape.

LncRNA NPTN-IT1-201 Ameliorates Depressive-like Behavior by Targeting miR-142-5p and Regulating Inflammation and Apoptosis via BDNF.

Objective: Long noncoding RNAs (lncRNAs) and microRNAs (miRNAs) are widely expressed in the brain and are associated with the development of neurological and neurodegenerative diseases. However, their roles and molecular mechanisms in major depressive disorder (MDD) remain largely unknown. This study aimed to identify lncRNAs and miRNAs involved in the development of MDD and elucidate their molecular mechanisms.

Identification of key genes and crucial pathways for major depressive disorder using peripheral blood samples and chronic unpredictable mild stress rat models.

Background: Accurate diagnosis of major depressive disorder (MDD) remains difficult, and one of the key challenges in diagnosing MDD is the lack of reliable diagnostic biomarkers. The objective of this study was to explore gene networks and identify potential biomarkers for MDD.

Methods: In the present study, we performed a comprehensive analysis of the mRNA expression profiles using blood samples of four patients with MDD and four controls by RNA sequencing.

Increased miR‑187‑3p expression after cerebral ischemia/reperfusion induces apoptosis via initiation of endoplasmic reticulum stress.

Ischemia/reperfusion (I/R) injury induces activation of the endoplasmic reticulum stress (ERS) pathway, accompanied by an increase in apoptosis. Multiple microRNAs (miRNAs/miRs) are dysregulated during I/R and contribute to I/R-induced injury. miRNAs act as suppressors of gene expression and negatively regulate gene expression by targeting the protein-coding sequence (CDS) of specific target mRNAs.

Berberine Ameliorates Oxygen-glucose Deprivation/Reperfusion-induced Apoptosis by Inhibiting Endoplasmic Reticulum Stress and Autophagy in PC12 Cells.

This study aimed to elucidate the molecular mechanisms by which berberine protects against cerebral ischemia/reperfusion (I/R) injury. The oxygen-glucose deprivation/reperfusion (OGD/R) PC12 model was established. Cell counting kit-8 (CCK-8) was used to detect the toxicity of berberine and the viability of PC12 cells.

miR‑187‑3p inhibitor attenuates cerebral ischemia/reperfusion injury by regulating Seipin‑mediated autophagic flux.

MicroRNAs (miRNAs/miRs) have been reported to affect ischemia/reperfusion (I/R)‑induced cerebral damage. miRNAs cause post‑transcriptional gene silencing by binding to the protein‑coding sequence (CDS) of mRNAs. Seipin has a potential role in regulating autophagic flux.

PNU282987 inhibits amyloid‑β aggregation by upregulating astrocytic endogenous αB‑crystallin and HSP‑70 via regulation of the α7AChR, PI3K/Akt/HSF‑1 signaling axis.

Alzheimer's disease (AD) is a chronic and irreversible neurodegenerative disorder. Abnormal aggregation of the neurotoxic amyloid‑β (Aβ) peptide is an early event in AD. The activation of astrocytic α7 nicotinic acetylcholine receptor (α7 nAChR) can inhibit Aβ aggregation; thus, the molecular mechanism between α7 nAChR activation and Aβ aggregation warrants further investigation.

Astrocytic α7 Nicotinic Receptor Activation Inhibits Amyloid-β Aggregation by Upregulating Endogenous αB-crystallin through the PI3K/Akt Signaling Pathway.

Background: β-amyloid (Aβ) aggregation plays an important role in the pathogenesis of Alzheimer's disease (AD), and astrocytes can significantly inhibit Aβ aggregation. Astrocytic α7 Neuronal Nicotinic Acetylcholine Receptor (nAChR) upregulation detected in the AD brains is closely associated with Aβ deposits. However, the relationships between the astrocytic α7 nAChRs and Aβ aggregation remain unclear.
