Abstract:

 The objective of this paper was to explore if Cold-inducible RNA binding protein(CIRP) involved in the response of mice to LPS.Total 48 BALB/c mice were randomly divided into 4 groups,LPS was injected into abdominal cavity of each mouse in dose of 2.5,5,7.5 mg•kg-1 body weight for 1-3 experimental groups.The 4th group(control group) was injected with the same volume saline solution in the same way with the above groups.Three mice were selected in each group and euthanized at 3,6,12 and 18 h post injection.The heart,liver,spleen and kidney of each mouse were collected.Real-time RT-PCR established in this study and immunohistochemistry were used to detect the transcription of CIRP mRNA and expression of CIRP protein in each organ.The results showed that the Cirp mRNA significantly increased in liver,spleen and kidney post LPS injection,while Cirp mRNA transcription in heart was inhibited at all time points.CIRP protein was highly expressed in all detected organs after LPS stimulation.In conclusion,the results in this paper demonstrated that CIRP involves in response to LPS in mice and present evidence to identify new feature of CIRP.
