摘要 在骨关节病的研究中业已发现变性的软骨细胞DNA损伤,出现典型的细胞凋亡的“梯形”表现,说明变性的关节软骨存在细胞凋亡,而细胞凋亡受某些癌基因的调控。为了论证此设想,我们选择已被证明与细胞凋亡有关的3种癌基因(bc1-2,p53,c-myc)进行检测,结果证明,在骨关节病的软骨细胞中发现c-myc和p53阳性表达,其特点为在凋亡的软骨细胞中呈散在性表达,bc1-2则为阴性表达,说明骨关节病敕骨细胞癌基因表达有着自己的特性和调控细胞凋亡的共性。 Previous studies have suggested that damaged DNA showed ladder-like changes in programmed cells death(PCD)in os- teoarthrosis(OA).We used immunohistochemical methods to detect c-myc,p53,and bc1-2 expression of chondrocytes in oA.Results Showed that the expression of p53 and c-myc was positive and bc1-2 was negative.The expression property was dispersed in some of chondrocytes and differed from carcinoma.
