XXXX gene mutations in @entity1893 .

@entity1 @entity706 @entity575 @entity784 @entity876 @entity1892 @entity1893
To understand @entity876 gene change of @entity1893 ( @entity1893 ) and @entity1 @entity706 cell lines, the exons 5-7 of 29 @entity1 with @entity1893 and 9 kinds of @entity1 @entity706 cell lines were studied by @entity575 staining PCR-SSCP technique. Three cases of @entity876 gene point mutation was found in 29 cases of @entity1893 . Mutation developed in exon 5 in 2 cases, and in exon 6 in 1 case. They were all @entity706 . In mutation cases, @entity1892 accounted for 2 cases and the other one was @entity784 . There was no @entity876 gene mutation in low-grade @entity706 . Seven strains out of 9 kinds of @entity706 cell lines had @entity876 gene point mutation. One strain had the mutation in exon 5; 5 strains in exon 6 and 1 strain in exons 5, 6, 7. There was a high mutation rate in @entity706 cell lines and low mutation rate in @entity1893 @entity1 . @entity876 gene plays an important role in @entity706 cell line establishment, cell regeneration and disease evolution.
