To review the transcriptional transactivation mechanisms of the hepatitis B virus X protein (pX/HBx) and evaluate its role in the development of hepatocellular carcinoma.
Synthesized molecular and cellular literature examining the structural, signaling, and transcriptional activities of the 16.5 kDa HBV pX protein.
Evaluated functional evidence linking pX-mediated modulation of gene transcription, cell growth, and apoptosis to malignant transformation during chronic infection.
Characterized pX as a promiscuous transactivator that alters gene expression without binding DNA directly.
Identified a dual mechanism where pX activates mitogenic signaling cascades in the cytoplasm and binds bZip transcription factors and basal transcription machinery in the nucleus.
