Abstract
Significant progress has been made in the diagnosis and treatment of cancer; however, significant challenges remain. Conditionally replicating adenoviruses (CRAds), which not only kill cancer cells, but also serve as vectors to express therapeutic genes, are a novel and effective method to treat cancer. However, most adenoviruses are Ad5, which infect cells through the coxsackie and adenovirus receptor (CAR). The transduction efficacy of Ad5 is restricted because of the absent or low expression of CAR on several cancer cells. Ad serotype 35 has a different tropism pattern to Ad5. Ad35 attaches to cells via a non-CAR receptor, CD46, which is expressed widely on most tumor cells. Thus, chimeric adenoviral vectors consisting of the knob and shaft of Ad35 combined with Ad5 have been constructed. The chimeric fiber adenoviral vectors can transduce CAR-positive and CAR-negative cell lines. In this review, we explore the application of the novel fiber chimeric conditionally replicative adenovirus-Ad5/F35 in tumor therapy in terms of safety, mechanism, transduction efficacy, and antitumor effect.

Abstract
Oncolytic adenoviruses are a novel class of anticancer treatment, based upon their ability to replicate selectively within malignant cells resulting in cell lysis. The replication‑selective adenovirus, ZD55‑IL‑24, was constructed by harboring an E1B‑55 kDa deletion and arming with interleukin-24 (IL-24). The microtubule‑stabilizing drug paclitaxel (PTX) exhibits activity in relapsed cancer. In the present study, the synergistic antitumor effects of the combination of PTX and ZD55‑IL‑24 on breast cancer cells was investigated. The results demonstrated that there were different roles for PTX in the expression of transgenic mRNA and protein. ZD55‑IL‑24 combined with PTX induced marked growth inhibition of MDA‑MB‑231 and Bcap‑37 cells. PTX increased viral uptake and appeared not to alter the replication of ZD55‑IL‑24 in breast cancer cells. Annexin V‑fluorescein isothiocyanate/propidium iodide staining and the Hoechst 33258 assay indicated that ZD55‑IL‑24 induced an increase in the number of apoptotic cells when administered in combination with PTX. It was demonstrated that ZD55‑IL‑24 conjugated with PTX was highly concomitant, and increased proapoptotic proteins levels, activated caspase‑3, -7 and -9 and downregulated anti‑apoptotic proteins. These results suggested that ZD55‑IL‑24 in combination with PTX exhibited a markedly increased cytotoxic and apoptosis‑inducing effect in breast cancer cells. Thus, this chemo‑gene‑viro therapeutic strategy was demonstrated to be superior to conventional chemotherapy or gene‑viro therapy alone.

Abstract
BACKGROUND Clinical gene therapy trials for cardiovascular diseases have demonstrated the crucial role of efficient gene delivery and transfection technologies in achieving clinically relevant results. We hypothesized that the use of tropism-modified adenoviruses would improve transduction efficacy and to this end we analyzed the transduction efficiency and toxicity of standard Ad5 and tropism-modified Ad5/35 in combination with ultrasound-guided intramyocardial gene delivery. METHODS Ultrasound-guided intracardiac injections were used to deliver 1 × 10(10) pfu/ml Ad5-lacZ and Ad5/35-lacZ vectors into mouse left ventricle wall. Since Ad5/35 uses human CD46 as its primary receptor, we used transgenic hCD46Ge mice expressing human CD46 at levels comparable to man. Mice were sacrificed 6 or 14 days post-injection and immunohistochemistry and X-gal staining were used to detect transgene and viral receptor expression. Virus-induced cardiac toxicity was evaluated by a pathologist. RESULTS The intramyocardial injection was well tolerated and both Ad5-lacZ and Ad5/35-lacZ were able to give robust transgene expression after a single injection. Interestingly, while Ad5-lacZ was able to generate greater transgene expression than Ad5/35-lacZ, it also evoked more severe tissue damage with large areas of interstitial inflammatory cell infiltration and myocyte necrosis. CONCLUSIONS Ultrasound-guided intramyocardial injection is an effective and safe way to deliver vectors to the heart. The observed severe tissue damage of Ad5-lacZ greatly undermines the efficient transgene expression and suggests that Ad5/35 capsid modification can result in safer adenoviral vectors for cardiovascular gene therapy, although at the cost of some vector transduction efficacy.

Abstract
Malignant gliomas remain refractory to treatment despite advances in chemotherapy and surgical techniques. Conditionally replicating adenoviral vector (CRAd) could kill the tumor cells by selectively replicating in neoplastic cells, which represents a novel strategy for tumor therapy. Although CRAd with a 24-bp deletion in CR2 of the E1 region (CRAd5-D24) has been shown to have a better therapeutic effect over the other types of CRAd vectors, the current CRAd5-D24 still has some shortcomings for an efficient therapy of gliomas. In this study, we developed for the first time a novel vector CRAd5/11-D24.TRAIL/arresten by the following strategies: (1) modify CRAd5-D24 with Ad5/11 chimeric fiber to improve its infection efficiency for glioblastoma; and (2) insert two transgene expression cassettes into the E3 region and the region between the fiber and E4, respectively, for an enhanced therapeutic effect. The results indicated that the CRAd5/11-D24.TRAIL/arresten achieved nearly complete inhibition of glioma growth in nude mice possibly by increased antiangiogenesis and enhanced tumor apoptosis. The vector is the first reported E1A D24-deleted, Ad5/11 chimeric, and dual-armed oncolytic virus that shows markedly improved antitumor activities compared with the conventional oncolytic viruses. This novel antitumor agent should be evaluated further in future preclinical and clinical studies.

Cell entry and trafficking of human adenovirus bound to blood factor X is determined by the fiber serotype and not hexon:heparan sulfate interaction. PLoS One 2011; 6:e18205.

Abstract
Human adenovirus serotype 5 (HAdV5)-based vectors administered intravenously accumulate in the liver as the result of their direct binding to blood coagulation factor X (FX) and subsequent interaction of the FX-HAdV5 complex with heparan sulfate proteoglycan (HSPG) at the surface of liver cells. Intriguingly, the serotype 35 fiber-pseudotyped vector HAdV5F35 has liver transduction efficiencies 4-logs lower than HAdV5, even though both vectors carry the same hexon capsomeres. In order to reconcile this apparent paradox, we investigated the possible role of other viral capsid proteins on the FX/HSPG-mediated cellular uptake of HAdV5-based vectors. Using CAR- and CD46-negative CHO cells varying in HSPG expression, we confirmed that FX bound to serotype 5 hexon protein and to HAdV5 and HAdV5F35 virions via its Gla-domain, and enhanced the binding of both vectors to surface-immobilized hypersulfated heparin and cellular HSPG. Using penton mutants, we found that the positive effect of FX on HAdV5 binding to HSPG and cell transduction did not depend on the penton base RGD and fiber shaft KKTK motifs. However, we found that FX had no enhancing effect on the HAdV5F35-mediated cell transduction, but a negative effect which did not involve the cell attachment or endocytic step, but the intracellular trafficking and nuclear import of the FX-HAdV5F35 complex. By cellular imaging, HAdV5F35 particles were observed to accumulate in the late endosomal compartment, and were released in significant amounts into the extracellular medium via exocytosis. We showed that the stability of serotype 5 hexon:FX interaction was higher at low pH compared to neutral pH, which could account for the retention of FX-HAdV5F35 complexes in the late endosomes. Our results suggested that, despite the high affinity interaction of hexon capsomeres to FX and cell surface HSPG, the adenoviral fiber acted as the dominant determinant of the internalization and trafficking pathway of HAdV5-based vectors.

Abstract
In vivo gene transfer to the human respiratory tract by adenovirus serotype 5 (Ad5) vectors has revealed their limitations related to inefficient gene transfer, host antiviral response, and innate adenoviral toxicity. In the present work, we compared the cytotoxicity and efficiency of Ad5 and a chimeric Ad5F35 vector with respect to CFTR gene transfer to cystic fibrosis (CF) and non-CF human airway epithelial cells. We found that high doses of Ad5 vector had an adverse effect on the function of exogenous and endogenous CFTR. Results obtained with Ad5 capsid mutants suggested that the RGD motifs on the penton base capsomers were responsible for the negative effect on CFTR function. This negative interference did not result from a lower level of biosynthesis and/or altered cellular trafficking of the CFTR protein, but rather from an indirect mechanism of functional blockage of CFTR, related to the RGD integrin-mediated endocytic pathway of Ad5. No negative interference with CFTR was observed for Ad5F35, an Ad5-based vector pseudotyped with fibers from Ad35, a serotype that uses another cell entry pathway. In vitro, Ad5F35 vector expressing the GFP-tagged CFTR (Ad5F35-GFP-CFTR) showed a 30-fold higher efficiency of transduction and chloride channel correction in CFTR-deficient cells, compared with Ad5GFP-CFTR. Ex vivo, Ad5F35-GFP-CFTR had the capacity to transduce efficiently reconstituted airway epithelia from patients with CF (CF-HAE) via the apical surface, restored chloride channel function at relatively low vector doses, and showed relatively stable expression of GFP-CFTR for several weeks.
