The work was to study ,in vitro, the effects of ionizing radiations on the expression of 1α-hydroxylase in renal tubular epithelial cells, which were exposed to 3Gy, 5Gy and10Gy by ,137,Cs γ-rays. By using Real-time Q-PCR technology and transmission electron microscopy (TEM), changes in the 1α-hydroxylase mRNA level and the mitochondria ultrastructure after the irradiation were compared with the control(0Gy) group. An obvious decrease in the 1α-hydroxylase mRNA expression was found after the 3Gy irradiation, and the decreasing rate increased with the irradiation dose. The TEM results also showed that with the irradiated cells the mitochondria swelled obviously, the electron density decreased , and the cristae arrangement breaked and disordered.
