In 1G5 , a Jurkat-derived T cell line stably transfected with a luciferase gene driven by HIV-1 long terminal repeat ( LTR ), we found that PGE2 markedly enhanced HIV-1 LTR -mediated reporter gene activity .
 ( DNA: luciferase gene, None) , ( cell line: 1G5, None) , ( DNA: HIV-1 LTR, None) , ( DNA: LTR, None) , ( DNA: reporter gene, None) , ( DNA: HIV-1 long terminal repeat, None) , ( cell line: Jurkat-derived T cell line, None)
