Expression of novel cloned genes HC56, HC71 and HC90 mapped on human chromosome 17p13.3 in leukemic cells / 中国实验血液学杂志

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 alpha(32)P dATP, betaM2 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.
