The ends of HCV RNA are conserved. HCV core protein is a multifunctional protein with a role in apoptosis-antiapoptosis regulation of cell multiplication and tumor control. [29] The death domain of tumor necrosis factor 1 and the cytoplasmic tail of lymphotoxin beta bind to the core protein. Nuclear factor kappa B (NF-kB) is activated in core peptide-transfected hepatoma cells and in HCV-infected liver tissue. NF-kB activation causes resistance to apoptotic signals in transfected HCV-containing cells. An evasion mechanism of host surveillance by means of NF-kB activation is proposed as one method of viral persistence in the chronic hepatitis C state and in carcinogenesis.
