Abstract
Oncolytic adenoviruses (OAds) have attracted much attention as novel anticancer agents. Numerous studies have examined the antitumour effects of combinational use of an OAd and anticancer agents; however, few chemical compounds enhancing OAd infection have been reported. In this study, we screened a food and drug administration (FDA)-approved drug library containing 1134 small chemical compounds to identify chemical compounds that enhance OAd replication in human tumour cells. We found that domperidone, a dopamine D2 receptor antagonist, significantly enhanced the replication of an OAd in human tumour cells, including human pancreatic tumour cells, by two-fivefold, resulting in improvement of OAd-mediated tumour cell killing activities. The E1A mRNA levels were significantly increased in domperidone-pre-treated cells following OAd infection, which contributed to the promotion of OAd replication. However, mRNA levels of the dopamine D2 receptor (DRD2), which is known to be a target molecule of domperidone, were undetectable in most of the tumour cells by real-time reverse transcription (RT)-PCR analysis, indicating that domperidone promoted OAd replication by acting on a molecule other than DRD2. This study provides important clues for the improvement of OAd-mediated cancer therapy.

Abstract
Replication-incompetent adenovirus (Ad) vectors are promising gene delivery vehicles, especially for hepatocytes, due to their superior hepatic tropism; however, in vivo application of an Ad vector often results in hepatotoxicity, mainly due to the leaky expression of Ad genes from the Ad vector genome. In order to reduce the Ad vector-induced hepatotoxicity, we previously developed an Ad vector containing the sequences perfectly complementary to a liver-specific microRNA (miRNA), miR-122a, in the 3'-untranslated region (UTR) of the E4 gene. This improved Ad vector showed a significant reduction in the leaky expression of Ad genes and hepatotoxicity in the mouse liver and primary mouse hepatocytes; however, the safety profiles and transduction properties of this improved Ad vector in human hepatocytes remained to be elucidated. In this study, we examined the transgene expression and safety profiles of Ad vectors with miR-122a-targeted sequences in the 3'-UTR of the E4 gene in human hepatocytes from chimeric mice with humanized liver. The transgene expression levels of Ad vectors with miR-122a-targeted sequences in the 3'-UTR of the E4 gene were significantly higher than those of the conventional Ad vectors. The leaky expression levels of Ad genes of Ad vectors with miR-122a-targeted sequences in the 3'-UTR of the E4 gene in the primary human hepatocytes were largely reduced, compared with the conventional Ad vectors, resulting in an improvement in Ad vector-induced cytotoxicity. These data indicated that this improved Ad vector was a superior gene delivery vehicle without severe cytotoxicity for not only mouse hepatocytes but also human hepatocytes.

Abstract
BACKGROUND/AIM Oncolytic adenoviruses (OAds) have attracted much attention as novel anticancer therapeutics. The proper design of an expression cassette containing the E1A gene, which is indispensable for self-replication of the Ad genome, is crucial for efficient tumor cell-specific infection of an OAd. Various types of oncolytic adenoviruses (OAds) possessing different types of the E1A gene expression cassettes have been developed, but their oncolytic activities and safety profiles have not been systematically evaluated. Herein we examined the oncolytic activities and safety profiles of five types of OAds possessing different types of the E1A gene expression cassette in order to optimize the E1A gene expression cassette for development of an efficient and safe OAd. MATERIALS AND METHODS We prepared five types of OAds containing different types of E1 gene expression cassettes, and examined the oncolytic activities and safety profiles of the OAds. RESULTS Among the OAds examined, OAd-Δ24, which had a 24-bp deletion in the E1A gene, mediated the most efficient oncolytic activities against the human tumor cell lines, although OAd-Δ24 showed slightly higher cytotoxicity to normal human cells than the other OAds. CONCLUSION These results provide important clues for the development of safe and efficient OAds.

Abstract
Clustered regularly interspaced short palindromic repeat (CRISPR)-CRISPR associated proteins (Cas) 9 system is a powerful tool for genome editing and still being aggressively improved. Cas12a, a recently discovered Cas9 ortholog, is expected to become complementary to Cas9 due to its unique characteristics. Previously we attempted to establish an adenovirus (Ad) vector-mediated delivery of CRISPR-Cas12a system since Ad vector is widely used for gene transfer in basic researches and medical applications. However, we found difficulties preparing of Ad vectors at an adequate titer. In this study, we have developed Ad vectors that conditionally express Cas12a either by a tetracycline-controlled promoter or a hepatocyte specific promoter to avoid putative inhibitory effects of Cas12a. These vectors successfully proliferated in packaging cells, HEK293 cells, and were recovered at high titers. We have also developed packaging cells that express shRNA for Cas12a to suppress expression of Cas12a. Using the cells, the Ad vector directing constitutive expression of Cas12a proliferated efficiently and was successfully recovered at a high titer. Overall, we improved recovery of Ad vectors carrying CRISPR-Cas12a system, thus provided them as a tool in genome editing researches.
