Increasing evidence suggests that human cytomegalovirus (HCMV), a beta-herpes virus that chronically infects human beings, is associated with colorectal cancer (CRC). The viral nucleic acids specifically localized to the neoplastic mucosal epithelium of CRC, while tumoral presence of HCMV independently predicted a poor outcome in elderly patients. In the past decade, the concept of "oncomodulat...

Background and Aim: Human cytomegalovirus (HCMV) has the potential for oncogenicity and has been associated with many malignancies, including prostate cancer. This study aimed to investigate the genomic prevalence of HCMV in prostate cancer tumors. Materials and Methods: In this case-control study, 31 patients with prostate cancer were enrolled along with 31 patients with benign prostate cance...

We examined the effect of Kampo on the replication of ganciclovir (GCV)-resistant human cytomegalovirus (HCMV) in the human embryonic fibroblast cell line MRC-5. Treatment of HCMV-infected cells with Sho-seiryu-to (SST; Xiao-Qing-Long-Tang in Chinese) resulted in the inhibition of viral replication without affecting the cell growth. SST treatment decreased the synthesis of viral DNA, but had no...

A novel fusion assay was established to determine fusion activity with cocultivated human foreskin fibroblasts of stable transfectants derived from human astrocytoma cells (U373) expressing authentic or mutagenized human cytomegalovirus glycoprotein B (HCMV gB; gpUL55). Compared to transfectants expressing authentic HCMV gB, those expressing gB forms with a deletion of hydrophobic domain 1 (hd1...

Human cytomegalovirus (HCMV) gB is known to play important roles in cell surface attachment, virion penetration, spread of infection from cell to cell, and provocation of neutralizing antibody. This study was performed to determine the role of anti-HCMV gB antibody in overall neutralizing response in patients with HCMV infection and healthy control with past infection. HCMV gB was stably expres...

The role of NF-kappaB in regulating human cytomegalovirus (HCMV) replication and gene transcription remains controversial. Multiple, functional NF-kappaB response elements exist in the major immediate-early promoter (MIEP) enhancer of HCMV, suggesting a possible requirement for this transcription factor in lytic viral replication. Here we demonstrate by generating and analyzing HCMVs with alter...

Human cytomegalovirus (HCMV) is a frequent cause of major disease following primary infection or reactivation from latency in immunocompromised patients. It has also been suggested that there may be a link between HCMV and vascular disease. Both smooth muscle and endothelial cells are targets for primary infection with HCMV and have also been postulated as potential sites of HCMV latency. One o...
