【摘要】 为研究人类染色体 1 7p1 3 .3位点新克隆的基因HC56 ,HC71和HC90在白血病细胞中的表达 ,应用同位素标记的、以 βM 2基因作为内参的半定量RT PCR法 ,检测 35例急性白血病和 4株白血病细胞系的HC56 ,HC70和HC90基因的表达。结果显示 ,急性淋巴系白血病病人的HC90基因和T淋巴系白血病细胞系Jurkat细胞HC90基因表达水平降低。急性髓系白血病病人HC71基因表达水平降低。HC56基因表达在急性白血病和正常对照间未见显著差异。结论 :在人类白血病有HC70和HC90的基因表达异常。更多还原

【Abstract】 In order to investigate expression of novel genes HC56, HC70 and HC90 mapped on chromosome 17p13.3 in human leukemic cells, HC56, HC71 and HC90 genes expression was examined in cells from 35 patients with acute leukemias and 4 leukemic cell lines by using semi quantitative RT PCR with incorporation of α 32 P dATP, βM2 gene as endogenous control. The results showed that HC90 gene expression level was lower in patients with acute lymphocytic leukemia and T lymphocytic leukemic cell line Jurkat than that in normal control. Low level HC71 gene expression was detected in acute myeloid leukemia. There was no expression difference in HC56 between leukemic cells and normal blood cells. It was concluded that both HC70 and HC90 genes were aberrantly expressed in human leukemic cells.更多还原
