ABSTRACT
This study investigated whether chemerin/chemokine-like receptor 1 (CMKLR1) pathway participate in cisplatin-induced spiral ganglion neuron (SGN) damage. Middle cochlear turn was collected from C57BL/6 mice and the SGNs were cultured. Cisplatin, 2-(anaphthoyl) ethyltrimethylammonium iodide (α-NETA), or recombinant mouse chemerin was added into the medium for the treatment. Relative mRNA and protein expression was determined by RT-PCR, ELISA and Western blot, respectively. In cultured mouse cochlear SGNs, the treatment of cisplatin enhanced the secretion of chemerin and CMKLR1. Recombinant chemerin promoted but α-NETA inhibited chemerin/CMKLR1 pathway in cisplatin stimulated SGNs. Cisplatin-induced apoptosis and inflammation response in SGNs were enhanced by recombinant chemerin while inhibited by α-NETA. Recombinant chemerin promoted but α-NETA inhibited NF-κB signal in cisplatin stimulated SGNs. In conclusion, chemerin/CMKLR1 pathway regulated apoptosis and inflammation response in cisplatin-induced SGN injury through NF-κB signaling pathway.
