This study examined the effects of exposure to low concentrations (0.1-100 nM) of bisphenol A (BPA) or nonylphenol (NP) on neuronal differentiation in pheochromocytoma PC12 cells. Pre-exposure to BPA for a week or a month, but not for a day, decreased neuronal differentiation in PC12 cells. Likewise, one week's pre-exposure to NP also inhibited neuronal differentiation in these cells. The inhibitory effects were still observed when PC12 cells were treated with BPA or NP for a week, followed by a week's withdrawal. These findings suggest that long-term exposure of PC12 cells to low concentrations of BPA or NP leads to changes in the cellular machinery responsible for neuronal differentiation, and these changes might be retained within PC12 cells.

The anti-inflammatory effect of phellodendrine (PHE), derived from Phellodendri Chinensis Cortex, has been verified in previous studies. Major depressive disorder (MDD) is associated with immune dysregulation and inflammatory processes. This study aimed to explore the therapeutic effects of PHE on MDD through network pharmacology and experimental validation.

Aluminum is a well-known and widely distributed environmental neurotoxin. This study aimed to investigate the effect of miR-98-5p targeting insulin-like growth factor 2 (IGF2) on aluminum neurotoxicity. Thirty-two Sprague-Dawley rats were randomly divided into four groups and administered 0, 10, 20, and 40 μmol/kg maltol aluminum [Al(mal)], respectively.

Unlabelled: Alzheimer's disease (AD) is a progressive neurological condition that causes brain shrinkage and cell death. This study aimed to identify the role of the NORAD/miR-26b-5p axis in AD. StarBase was used to examine the binding sequences of miR-26b-5p to LncRNA NORAD or its target genes, which were verified by a double luciferase reporter assay.
