ABSTRACT
<p><b>OBJECTIVE</b>To determine the transcription of SDF-1alpha in peripheral blood lymphocytes (PBL) and analysis the correlation between SDF-1alpha transcription and HIV infection.</p><p><b>METHODS</b>Three groups of study subjects were recruited (1) 97 HIV negative healthy donors, (2) 92 HIV patients of A1 to A3 stages and (3) 146 HIV patients of B1 to C3 stages. Total RNA was extracted from PBL. Reverse transcription (RT)-PCR and quantification PCR were developed for the SDF-1alpha transcriptional study. R1 value was calculated based on the ratio of SDF-1alpha copies to beta-globin copies.</p><p><b>RESULTS</b>SDF-1alpha transcription is heterogeneous among the three study groups. The SDF-1alpha transcription was significantly up-regulated during late stage of HIV infection than the healthy donors. Correlation analysis indicated that R1 value was negatively correlated to CD4+ T cells counts (P = 0.002); and positively correlated to virus load (P = 0.001). The result demonstrated an association between SDF-1alpha transcription and disease progression.</p><p><b>CONCLUSION</b>SDF-1alpha transcription was significantly up-regulated during late stage of HIV infection. It would be worthwhile to determine the mechnism of HIV affecting on SDF-1alpha genes transcription and the up-regulated SDF-1alpha expression on the disease progression.</p>
