摘要

The rats were fed with water dissolved Y~(3+) at different levels (0, 53 .4, 5340 mg centre dot L~(-1)) for 7 months . The gene expression in brain tissue was detected with oligonucleotide microarray. The results show that, compared to the control, 789 genes express differentially, 507 over-expressed genes and 282 under-expressed genes in the high-dose group (5340 mg centre dot L~(-1)), of which, most were related to cell receptor, cell signal and transmission, and ionic passage. 44 genes were found to express differentially including 32 over-expressed genes and 12 under-expressed genes in the low-dose group (53. 40 mg centre dot L~(-1)), of which, most were related to cell skeleton and movement, immunity, and DNA binding protein . These results suggest that Y3 + can change the expression of some genes, which may be responsible for the toxicity of rare earths on learning and memory.
