Abstract

Background: The global effect of HIV infection on the host cell gene expression profiles in healthy HIV-infected patients, as long-term non-progressors, remains largely unknown. To identify the cellular genes related with HIV infection and delayed disease progression in vivo, the host gene expression profiles between healthy HIV-infected Koreans and AIDS patients were investigated.
Methods: Differential expression gene analysis was performed via oligonucleotide microarray with using Magic-oligo 10K chip. Ten HIV-uninfected persons and 10 HIV-infected patients (healthy HIV-infected patients vs. AIDS patients. respectively) were studied.
Results: Only 10.8% (1,097 genes) of the total genes, that is, 331 up-regulated genes and 766 down- regulated genes were differentially expressed with more than a two-fold change in the HIV-infected persons as compared to those of the HIV-uninfected persons. Especially, 97 genes (8.8%) among 1,097 genes were commonly up- or down-regulated in both the healthy HIV-infected patients and the AIDS patients. 187 genes were differently expressed on the gene expression analysis between the healthy HIV-infected patients and the AIDS patients. Twenty-eight genes out of them showed very significant differences with a P value ＜0.01. Especially, tripartite motif (TRIM) 14 protein and interferon gamma receptor 2 were dramatically up-regulated in healthy HIV-infected patients, while death-associated protein, DNA directed RNA polymerase II polypeptide A and STAT were over-expressed in AIDS patients.
Conclusion: Although this microarray study has some limitations, the above results will be helpful for performing more detailed, future functional studies on the differentially expressed genes related to HIV infection and delayed disease progression in vivo. (Korean J Hematol 2007;42:33-42.)
