The results indicated that the neuron injury marker activating transcription factor 3 (ATF3) was markedly increased and neuronal excitability was significantly increased 1 month post-radiation in the lumbar dorsal root ganglion (DRG). Yet, radiation-induced chronic pain could not be mitigated by common analgesics. We discovered that endoplasmic reticulum (ER) stress was activated in the DRG, and intraperitoneal injections of the ER stress antagonists 4-phenylbutyric acid (4-PBA) and TUDCA significantly alleviated mechanical and thermal allodynia. Additionally, 4-PBA and TUDCA reduced the neuronal hyperexcitability caused by radiation. Moreover, 4-PBA also ameliorated the motor dysfunction induced by high-dose radiation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Interpretation<\/jats:title>\n                    <jats:p>Our findings highlight the pivotal role of ER stress activation in the development of chronic neuropathic pain induced by high doses of radiation.
