The present study aimed to investigate NET formation after exposure to high‑dose ionizing radiation and to explore the underlying role of the eCIRP/TREM‑1 axis as its mechanism. Bone marrow‑derived neutrophils (BMDNs) isolated from C57BL/6 mice were exposed to 5 to 15 Gy irradiation.

TREM‑1 cell surface expression on neutrophils was assessed using flow cytometry. Peptidyl arginine deiminase 4 (PAD4) protein expression levels in BMDNs were evaluated using western blotting. TREM‑1 and PAD4 mRNA expression levels in BMDNs were assessed using reverse transcription‑quantitative PCR. In vitro irradiation of neutrophils resulted in a dose‑dependent increase in NET formation, as assessed using flow cytometry and validated using fluorescence microscopy, which demonstrated the characteristic long extracellular DNA structures of NETs in irradiated neutrophils. The <i>in vivo</i> mouse model of TBI exhibited similar results. Furthermore, TREM‑1 expression in BMDNs was significantly increased after irradiation. Protein and mRNA levels of PAD4 were significantly upregulated after irradiation. The addition of eCIRP to BMDNs further increased NET formation post‑irradiation <i>in vitro</i>. Conversely, knockout of CIRP and TREM‑1 <i>in vivo</i> significantly attenuated radiation‑induced NET formation compared with that of WT mice.

Our data revealed that the expression of SDF2 was upregulated in glioma tissues. In glioma cell lines, SDF2 promoted cell proliferation and migration, whereas the knockdown of SDF2 (Ad‑shSDF2) induced cell death. Further investigations revealed that the copper chelator tetrathiomolybdate (TTM) could reverse the reduction in cell viability caused by Ad‑shSDF2. Upon SDF2 knockdown, the expression of ATP7A and ATP7B was decreased in glioma cells, whereas the expression of glucose‑regulated protein 78 (GRP78) was increased. Moreover, the proteasome inhibitor MG132 and the silencing of GRP78 effectively blocked the Ad‑shSDF2‑mediated decrease in ATP7A and ATP7B expression, as well as the accumulation of dihydrolipoamide S‑acetyltransferase in mitochondria. <i>In vivo</i>, SDF2 promoted subcutaneous tumor growth in nude mice, an effect that could be reversed by overexpression of GRP78.
