Preferential HIV-1 integration sites in macrophages and HIV-associated malignancies

Cell Mol Biol (Noisy-le-grand). 2004:50 Online Pub:OL581-9.

Abstract

HIV-infected individuals are at risk for developing certain types of cancers. While there are data to show that non-random HIV integration may occur, our goal was to identify preferential genomic sites where HIV integration might be targeted leading to oncogenesis. Initially, a linker-primer PCR strategy was used to identify HIV integration in isolated macrophages. Inverse-PCR was then used to analyze specimens from patients diagnosed with HIV-associated malignancies. From isolated macrophages, integration near a toll-like receptor on chromosome 4 was found. Necropsy tissues from 11 cases were analyzed with 1 tumor specimen found to have HIV integrated in chromosome 22q13.2 and within 300 kb of HSCBCIP1 (CAP-binding protein complex interacting homologue). Tumor-specific primers were then used to screen uninvolved tissue from the same patient, which did not amplify the site-specific region. This report demonstrates that in both an in vitro system and human malignant tissue, specific viral integration can be identified.
