ABSTRACT
Objective To investigate the effect of X-ray irradiation on the expression of free ubiquitin in the serum, small intestine, and heart tissues of C57 BL/6N mice. Methods The amount of free ubiquitin protein in the serum and tissue homogenates was analyzed quantitatively with ELISA and Western Blotting assay. The mRNA expressions of free ubiquitin in the tissues were detected by RT-PCR. Results At 24 or 48 h after radiation, the free ubiquitin level in the serum and small intestine tissue increased asymptotically with increasing of radiation dose (F=183?1, 435?3, P 0?05). Conclusions Because of the high expressions of free ubiquitin protein in the radiosensitive mice tissues, X-ray radiation could increase the concentration of free ubiquitin in serum. The changes of free ubiquitin may be related to cellular radiosensitivity and tissue injury.
