ABSTRACT
<p><b>OBJECTIVE</b>To find the novel gene related to the multi-drug resistance in leukemia and explore the molecular mechanism of multi-drug resistance.</p><p><b>METHODS</b>The subtracted HL-60/VCR cDNA library was generated through the suppression subtractive hybridization using the wild HL-60 cells' cDNA as target and HL-60/ ATRA cells' as driver. A novel expression sequence tag (EST) sequence, which differentially expressed in HL-60/ ATRA cell, was screened by cDNA chip. Then a novel human gene, HV126 was assembled by the EST assembly tools. Bioinformatical databases and softwares were used to analyze and predict its function. Reverse transcription-PCR (RT-PCR) was used to detect the expression of HV-126 gene in leukemia cells before and after chemotherapy.</p><p><b>RESULTS</b>The full open reading frames (ORFs) of the novel EST assembled by overlapping dbEST sequences included a 1991 bp nucleic sequence, which was named HV126. The deduced amino acid sequence consisted of 365 amino acids. The sequence of the novel gene exhibited 43% homology to a known gene, which is a possible member of the death domain-flood family implicated in apoptosis and inflammation. The expression of HV126 was proved to be related to the drug sensitivity in leukemia cells by RT-PCR.</p><p><b>CONCLUSION</b>HV126, the novel gene, might have roles in regulating multi-drug resistance in leukemia. Further laboratory research should be done on cloning and making clear the gene function.</p>
