Lycopene protection against DEHP-induced neurotoxicity in mice

Validation Score: 0.900 Price: $0.50 DEHP-induced neurotoxicity mice Status: proposed

What This Experiment Tests

Validation experiment designed to validate causal mechanisms targeting N/A in mice. Primary outcome: anxiety- and depression-like behaviors

Description

This comprehensive animal study investigated the neuroprotective effects of lycopene (Lyc) against di(2-ethylhexyl) phthalate (DEHP)-induced neurotoxicity in mice over 35 consecutive days. The experiment utilized a multi-faceted approach combining behavioral assessments, molecular biology analyses, transcriptomics, and microbiome profiling to understand the gut-brain axis mechanisms. Mice received daily intragastric administrations of either DEHP (to induce neurotoxicity) or Lyc (as treatment). The study evaluated anxiety- and depression-like behaviors, neuroinflammation in the hippocampus, gut microbiota composition, intestinal barrier integrity, and inflammatory signaling pathways. Key findings showed that Lyc administration effectively ameliorated DEHP-induced behavioral deficits, reduced hippocampal neuroinflammation through modulation of NOD-like receptor signaling, improved gut microbiota by promoting beneficial bacteria like Akkermansiaceae, enhanced intestinal barrier function via increased tight junction proteins, and regulated LPS-TLR4/MyD88 signaling in the colon to reduce local inflammation.
