Integrated Transcriptomics and Proteomics Reveal Ferroptosis Induced by B[a]P and BPDE in Mouse Hippocampal Neurons
This study comprehensively investigates the neurotoxic effects of Benzo[a]pyrene (B[a]P) and its metabolite B[a]P-7,8-diol-9,10-epoxide (BPDE) on mouse hippocampal neurons, focusing on ferroptosis as a key mechanism. Through integrated transcriptomics and proteomics, combined with machine learning, a detailed network was delineated, showing that BPDE inhibits iron, amino acid, and carbohydrate transport, reduces ATP, increases ROS, and promotes autophagy, leading to metabolic imbalance and ferroptosis. These findings highlight ferroptosis as a critical pathway in B[a]P/BPDE neurotoxicity and suggest new therapeutic avenues for cognitive dysfunction.

Neurotoxicity
The study directly addresses the neurotoxic effects of B[a]P/BPDE, demonstrating hippocampal neuronal damage, cognitive impairment, and specific molecular pathways leading to cell death.
Ferroptosis Mechanism
A core finding is the identification of ferroptosis as a key programmed cell death mechanism induced by B[a]P/BPDE, detailing the involvement of lipid peroxidation, iron overload, and the protective role of Ferrostatin-1.
Multi-Omics Integration
The research leverages advanced multi-omics (transcriptomics and proteomics) combined with machine learning to construct a comprehensive network of molecular interactions, offering a systems-level understanding of BPDE-induced ferroptosis.
8.5%
Reduction in Neuronal Count (High-Dose B[a]P)
High-dose B[a]P exposure led to an approximate 8.5% reduction in neuronal count in hippocampal CA1/CA3 regions, indicative of significant neurotoxicity.

BPDE significantly disrupted key cellular processes related to ferroptosis, which were largely ameliorated by Ferrostatin-1 treatment.
In Vivo Confirmation: B[a]P & Cognitive Impairment
Company: Mouse Model Study
Challenge: To determine if B[a]P exposure induces cognitive impairment and neuronal ferroptosis in vivo.
Solution: Sub-chronic intragastric administration of B[a]P in mice, followed by MWM and Y-maze tests, histological analysis, and ferroptosis biomarker assessment.
Results: B[a]P-exposed mice showed dose-dependent learning and memory deficits (prolonged escape latency, reduced novel arm exploration). Hippocampal neurons exhibited atrophy, mitochondrial damage, increased iron content, decreased GSH/GSH-Px, and elevated MDA. Ferrostatin-1 treatment significantly mitigated these effects, confirming ferroptosis as a key mechanism in vivo.
Impact: This in vivo model validates the B[a]P-induced neurotoxicity and the role of ferroptosis, providing a strong basis for human health risk assessment and therapeutic strategies.
