Development of gene model combined with machine learning technology to predict for advanced atherosclerotic plaques.

Background: Atherosclerosis, as a major cause of stroke, is responsible for a quarter of deaths worldwide. In particular, rupture of late-stage plaques in large vessels such as the carotid artery can lead to serious cardiovascular disease. The aim of our study was to establish a genetic model combined with machining leaning techniques to screen out gene signatures and predict for advanced atherosclerosis plaques.

Identifying the potential role of serum miR-20a as a biomarker for olfactory dysfunction in patients with Parkinson's disease.

Introduction: Olfactory dysfunction (OD), one of the most common non-motor symptoms in Parkinson's disease (PD), is a cardinal prodromal symptom that can appear years before the onset of motor symptoms. Ongoing studies have demonstrated that microRNAs (miRNAs) are suitable biomarkers for PD, while there is a lack of robust miRNAs that can serve as markers for OD in PD.

Methods: The concordantly differentially expressed miRNAs (DE miRNAs) in the damaged olfactory system were first identified in 2 OD-related Gene Expression Omnibus (GEO) datasets.

Protective Effects of Querectin against MPP-Induced Dopaminergic Neurons Injury via the Nrf2 Signaling Pathway.

Background: Parkinson's disease (PD) is a common selective and progressive neurodegenerative disorder of nigrostriatal dopaminergic (DA) neurons. Quercetin is a bioflavonoid with antioxidant, anti-inflammatory, anti-aging and anti-cancer properties. However, the exact mechanism by which quercetin exerts its protective effect on DAergic neurons remains unclear.

Targeting gut-brain axis through scalp-abdominal electroacupuncture in Parkinson's disease.

Background: Evidence suggests that the pathogenesis of Parkinson's disease (PD) is initiated in the gut rather than in the brain. Thus, targeting the gut in early stages may have the potential to halt disease progression and alleviate symptoms. Various acupuncture techniques have been used to treat patients with PD and have shown promising results.

The neuroprotective effects of paeoniflorin against MPP-induced damage to dopaminergic neurons via the Akt/Nrf2/GPX4 pathway.

Paeoniflorin (PF), a water-soluble monoterpene glycoside extracted from the root of Paeonia lactiflora Pall, has been shown to exert neuroprotective effects against neurodegenerative diseases such as Parkinson's disease (PD). However, its underlying mechanisms remain unknown. Our results showed that at certain concentrations, PF alleviated 1-methyl-4-phenylpyridinium (MPP)-induced morphological damage and inhibited neuronal ferroptosis.

Identification of chaperones in a MPP-induced and ATRA/TPA-differentiated SH-SY5Y cell PD model.

Parkinson's disease (PD) is characterized by the pathological accumulation of misfolded proteins. Molecular chaperones assist in the proper folding of proteins and removal of irreversibly misfolded proteins. This study aims to identify potential chaperones associated with protein misfolding and accumulation in PD.

HDAC6 α-tubulin deacetylase: a potential therapeutic target in neurodegenerative diseases.

Histone deacetylases (HDACs), or lysine deacetylases (KDAC), are epigenetic regulators that catalyze the removal of acetyl moieties from the tails of lysine residues of histones and other proteins. To date, eighteen HDAC family members (HDAC1-11 and SIRT1-7) have been identified and grouped into four classes according to their homology to yeast histone deacetylases. HDACs play an important role in regulating gene transcription as well as a variety of cellular functions.

Proteomics analysis of methylglyoxal-induced neurotoxic effects in SH-SY5Y cells.

Reactive carbonyl compounds contribute to aging, Alzheimer's disease (AD) and other neurodegenerative diseases. Among these compounds, methylglyoxal (MG) can yield advanced glycation end products (AGEs), which are crucial in AD pathogenesis. However, the molecular and biochemical mechanisms of MG neurotoxicity are not completely understood.

Proteomics analysis of MPP+-induced apoptosis in SH-SY5Y cells.

Accumulating evidence suggests that oxidative stress plays a pivotal role in dopaminergic neurodegeneration. However, the kinds of proteins involved in the response to oxidative stress remain unclear. In the present study, SH-SY5Y cells were treated with neurotoxin 1-methyl-4-phenyl-pyridinium ion (MPP+) to induce apoptotic neuronal injury.

SH-SY5Y human neuroblastoma cell line: in vitro cell model of dopaminergic neurons in Parkinson's disease.

Objective: To evaluate the human neuroblastoma SH-SY5Y cell line as an in vitro model of dopaminergic (DAergic) neurons for Parkinson's disease (PD) research and to determine the effect of differentiation on this cell model.

Data Sources: The data of this review were selected from the original reports and reviews related to SH-SY5Y cells published in Chinese and foreign journals (Pubmed 1973 to 2009).

Study Selection: After searching the literature, 60 articles were selected to address this review.
