Objective:
To identify the genes differentially expressed in leukemia cell apoptosis induced by recombinant soluble tumor necrosis factor-related apoptosis inducing ligand (rsTRAIL).
Methods:
Suppression subtractive hybridization (SSH) and polymerase chain reaction (PCR) were used for the cloning and identification of the genes differentially expressed in the apoptotic Jurkat cells induced by TRAIL. Slot blot and Northern blot were used for the expression pattern analysis of the genes. Automatic DNA sequencing was used for DNA sequence analysis.
Results:
Six cDNA fragments differentially expressed in the Jurkat leukemia cells treated with TRAIL were found, in which four were inhibited and two were activated during the Jurkat cell apoptosis treated with TRAIL. Among which the five genes of A14, X1, D1, A23 and C5 were found at the first time by DNA sequencing and GeneBank database searching. So that they were registered in GeneBank as AW731601, AW731602, AW731603, AW731604 and BE239235, respectively. It was found that the gene D1 was expressed higher in Jurkat leukemia cells and MCF-7 breast cancer cells than that in K562 leukemia, 825 gastric cancer and 7721 liver cancer cells.
Conclusions:
Five novel cDNA fragments were found, and among which D1 might be a tumor specific gene.
Insights
Recombinant soluble tumor necrosis factor-related apoptosis inducing ligand (rsTRAIL) induced differential gene expression in leukemia cells. Five novel cDNA fragments were identified, with D1 showing potential as a tumor-specific gene.
