CV706 is a prostate-specific antigen (PSA)-selective, replication-competent adenovirus that has been shown to selectively kill human prostate cancer xenografts in preclinical models. To study the safety and activity of intraprostatic delivery of CV706, a Phase I dose-ranging study for the treatment of patients with locally recurrent prostate cancer after(More)
Human glandular kallikrein (hK2) and prostate-specific antigen (PSA) are related members of the human kallikrein gene family. The genes for hK2 and PSA are expressed predominately in the prostate, are transcriptionally up-regulated by androgens, and share 78% homology. Previously, one functional androgen response element was identified within the proximal(More)
The purpose of this study was to examine the tumor specificity, cytotoxicity and the antitumor activity of two conditionally replicating oncolytic adenoviruses, SKL001 and SKL002, which expressed granulocyte macrophage colony-stimulating factor (GM-CSF) or anti-cytotoxic T lymphocyte-associated antigen-4 (CTLA4) antibody, respectively, and determine their(More)
CV787, a PSA+ prostate cell-specific adenovirus variant, is currently in Phase I/II clinical trials for the treatment of prostate cancer. We have previously demonstrated that a single administration of CV787 at 1 x 10(11) particle/animal could eliminate established tumors within 6 weeks in nude mouse xenografts (Yu et al., Cancer Res., 59: 4200-4203, 1999).(More)
Radiation is an effective means of treating localized prostate cancer. However, up to 40% of men with certain risk factors will develop biochemical failure 5 years after radiotherapy. CV706, a prostate cell-specific adenovirus variant, is currently in clinical trials for the treatment of recurrent organ-confined prostate cancer. We demonstrated previously(More)
CV787, a novel highly prostate-specific replication-competent adenovirus with improved efficacy, was constructed. CV787 contains the prostate-specific rat probasin promoter, driving the adenovirus type 5 (Ad5) E1A gene, and the human prostate-specific enhancer/promoter, driving the E1B gene. To improve efficacy, we constructed CV787 such that it also(More)
Pre-existent humoral antibody to adenovirus potentially confounds human clinical trials involving intravascular administration of adenovirus. Using the LNCaP prostate cancer xenograft model in BALB/c nu/nu mice and the prostate-specific attenuated replication-competent adenovirus (ARCATM) CN706, we developed an animal model that systematically controls both(More)
Hepatocellular carcinoma (HCC) is the third leading cause of cancer death in the world. Tumor resection remains the only curative treatment but is often not possible because of advanced stage and frequently unsuccessful because of intrahepatic or distant tumor recurrence. alpha-Fetoprotein (AFP), a tumor marker currently used for the diagnosis and(More)
The following study analysed apoptosis in proliferative cells and migrating neurons of the developing cerebellum. The external granular layer, Purkinje cell layer and internal granular layer in the developing mouse cerebellar cortex were analysed by active caspase-3 immunohistochemistry, Hoechst 33258 staining and Western blot analysis. Immunocytochemistry(More)
To study the tumor specificity and antitumor activity of the replication-competent oncolytic adenovirus TOA02, which is controlled by a modified human telomerase reverse transcriptase (hTERT) promoter and expresses granulocyte macrophage colony-stimulating factor (GM-CSF). The wild-type hTERT promoter was modified, by inserting two E2F-binding sites. The(More)
