PURPOSE Previous poor results of liver transplantation (LT) have been confirmed in patients with advanced hepatocellular carcinoma (HCC). Adenovirus-mediated delivery of herpes simplex virus thymidine kinase (ADV-TK) therapy is an established adjuvant treatment in cancer, and we evaluated its potential as an adjuvant treatment for HCC patients who underwent LT. EXPERIMENTAL DESIGN Forty-five ...

Aleutian disease virus (ADV) of mink is a nondefective parvovirus with a single-stranded DNA genome. We characterized the viral DNA forms found in infected cells prepared by a modified Hirt extraction procedure. Double-stranded DNA molecules corresponding in size to 4.8-kilobase-pair duplex monomers and 9.6-kilobase-pair duplex dimers were identified in agarose gels by blot hybridization to 32P...

Dendritic cells (DCs) are capable of presenting tumor-associated anti gens and subsequently play an essential role in T-cell activation. The aim of this study was to develop an efficient method for gene transfer into DCs. These genetically transduced DCs can then be used as potent inducers of specific cell-mediated immune response. When compared with physical methods for gene transfer (lipofect...

BACKGROUND Hepatitis B is a common infectious disease in China. Many studies have shown that the genotype of hepatitis B virus (HBV) is probably associated with the efficacy of some antiviral drugs such as interferon α (IFN-α) and Lamivudine (LAM). However, the association between HBV genotype and adefovir dipivoxil (ADV) is controversial. ADV is the most popular antiviral drug in China due to ...

PURPOSE Carbonic anhydrase 9 (CA9) is the most promising molecular marker described for renal cell carcinoma (RCC) to date. We investigated whether transduction of monocytes from peripheral blood with adenovirus encoding the CA9 gene (AdV-CA9) could stimulate a T-cell mediated immune response against cancer cells expressing CA9. The ability to consistently generate a T-cell response is an impor...

The benefits of treatment with antiviral therapy for severe adenovirus (AdV) pneumonia are not well established. We described the clinical characteristics and treatment outcomes of early cidofovir treatment of severe AdV pneumonia in non-immunocompromised patients. We retrospectively reviewed the medical records of all patients diagnosed with severe AdV pneumonia between 2012 and 2014. A total ...

Cancer gene therapy with adenovirus vectors (Adv) is limited to local administration because systemic administration of Adv produces a weak therapeutic effect and severe side effects. Previously, we generated a dual cancer-specific Adv system by using Adv covalently conjugated to polyethylene glycol (PEG) for transductional targeting and the telomere reverse transcriptase (TERT) promoter as a c...

Adenoviruses (AdV), causing fatal disseminated infections in bone marrow transplant (BMT) recipients, are associated not only with hemorrhagic cystitis (HC) but also with hepatitis, conjunctivitis, and viral interstitial pneumonia. The importance of this virus as a cause of disseminated disease, however, has remained underappreciated. AdV infection has been diagnosed primarily through the use o...

Our previous studies and those of others have indicated that X-linked inhibitor of apoptosis protein (XIAP) holds promise as a target gene in colon cancer gene therapy. In this study, we constructed an adenoviral vector to deliver small hairpin RNA (shRNA) against XIAP (XIAP-shRNA) into colon cancer cells and tested its therapeutic efficacy in vitro and in vivo. We first confirmed an overexpres...

The most serious problem of nucleoside/nucleotide analogue therapy for hepatitis B virus (HBV) infection is the emergence of drug-resistant mutant virus. Here, we describe a patient with chronic hepatitis B infection with a complex drug-resistant mutant virus during sequential therapy with lamivudine (3TC), entecavir (ETV) and adefovir dipivoxil (ADV). The patient was a 52-year-old male with po...
