Study of HepG2 cells transduced with HBX expressing recombinant Adenoviruses (AdHBx) and treated with UV

ABSTRACT: This SuperSeries is composed of the following subset Series: GSE11064: AdHBx UV vs AdEasy UV vs HepG2 GSE11106: Chromatin Immunoprecipitation of UV treated AdHBx cells with anti-HBx antibodies Keywords: SuperSeries One-condition experiment, AdHBx (experimental) UV vs AdEasy (vector control) UV. HepG2 cells were infected with either recombinant HBx adenoviruses (AdHBx) or control adenoviruses (AdEasy). Seventy-two hours later, infected cells were exposed for 30 seconds to UVC (254 nm) irradiation with a germicidal lamp calibrated to deliver 8 or 16 J/m2. Cells were then harvested for either ChIP-chip profiling or expression microarray profiling.

The hepatitis B-X (HBx) protein is strongly associated with hepatocellular carcinoma. It is implicated not to directly cause cancer but to play a role in hepatocellular carcinoma as a co-factor. The oncogenic potential of HBx primarily lies in its interaction with transcriptional regulators resulting in aberrant gene expression and deregulated cellular pathways. Utilizing ultraviolet irradiation to simulate a tumor-initiating event, we integrated chip-based chromatin immunoprecipitation (ChIP-ch  ...[more]
