Our preliminary experiment indicated the activation of with-nolysine kinases 1 (WNK1) in bone cancer pain (BCP) rats. This study aimed to investigate the underlying mechanisms via which WNK1 contributed to BCP. A rat model of BCP was induced by Walker-256 tumor cell implantation. ⋯ PERSPECTIVE: Our findings demonstrated that the WNK1-SPAK/OSR1 signaling contributed to BCP in rats via regulating NKCC1 and KCC2. Suppressing this pathway reduced pain behaviors. Based on these findings, the WNK1-SPAK/OSR1 signaling may be a potential target for BCP therapy.
