Effects of Rg3@PACVs with NIR in a Rat Model of Pulmonary Ischemia–Reperfusion Injury

Listed in NCBI GEO

Pulmonary ischemia–reperfusion injury (IRI) is characterized by excessive inflammation, oxidative stress, and mitochondrial dysfunction, leading to severe lung damage.

Description

To elucidate the molecular mechanisms underlying the protective effects of a macrophage membrane-coated mesoporous polydopamine nanoparticle system loaded with Ginsenoside Rg3 (Rg3@PACVs) combined with near-infrared (NIR) irradiation, we performed transcriptome sequencing of rat lung tissues.

Differential gene expression profiles were compared between IRI and IRI + Rg3@PACVs + NIR groups. A total of 209 upregulated and 332 downregulated genes were identified in the treatment group relative to IRI controls. Functional enrichment analyses revealed that Rg3@PACVs + NIR pretreatment enhanced pathways related to endoplasmic reticulum stress response, PI3K-AKT signaling, oxygen transport, protein folding, hypoxia response, TCA cycle activity, ATP-dependent processes, and cell cycle progression.

In contrast, inflammation-associated pathways including TLR/NF-κB signaling, cytokine binding, cell adhesion molecules, neutrophil extracellular trap formation, IL-1β production, and leukocyte trans-endothelial migration were significantly suppressed. GSEA further demonstrated reduced oxidative stress (cytochrome P450 activity) and enhanced FOXO signaling. These findings indicate that Rg3@PACVs + NIR mitigates pulmonary IRI by coordinately suppressing inflammatory responses, alleviating oxidative stress, and restoring mitochondrial homeostasis, thereby promoting lung tissue repair.
