Abstract:
Human immunodeficiency virus (HIV) is a retrovirus, belongs to Lentiviridae family. As long as viral genetic material entering into host cytoplasm, double-strand DNAs synthesis occurs which is catalyzed by reverse transcriptase (RT) with viral plus-strand RNA as template. This reverse transcription is a key link of HIV-1 life cycle and an important target for anti-HIV drug development. The process of reverse transcription can be divided into several steps: formation of minus-strand strong-stop DNA; the first translocation; initiation of plus-strand DNA synthesis; and, the second translocation and the completion of both strands. These steps can be detected individually by using polymerase chain reaction (PCR) according to the amplified products on the region of R/U5, U3, U5/PBS and the sequence between LTR and Gag. In this review, we summarize the principle for detecting stages of HIV-1 reverse transcription by using PCR.
