Abstract
Postprandial hyperglycemia is an early indicator of impaired glucose tolerance that leads to type 2 diabetes mellitus (T2DM). Alterations in the fatty acid composition of phospholipids have been implicated in diseases such as T2DM and nonalcoholic fatty liver disease. Lysophospholipid acyltransferase 10 (LPLAT10, also called LPCAT4 and LPEAT2) plays a role in remodeling fatty acyl chains of phospholipids; however, its relationship with metabolic diseases has not been fully elucidated. LPLAT10 expression is low in the liver, the main organ that regulates metabolism, under normal conditions. Here, we investigated whether overexpression of LPLAT10 in the liver leads to improved glucose metabolism. For overexpression, we generated an LPLAT10-expressing adenovirus (Ad) vector (Ad-LPLAT10) using an improved Ad vector. Postprandial hyperglycemia was suppressed by the induction of glucose-stimulated insulin secretion in Ad-LPLAT10-treated mice compared with that in control Ad vector-treated mice. Hepatic and serum levels of phosphatidylcholine 40:7, containing C18:1 and C22:6, were increased in Ad-LPLAT10-treated mice. Serum from Ad-LPLAT10-treated mice showed increased glucose-stimulated insulin secretion in mouse insulinoma MIN6 cells. These results indicate that changes in hepatic phosphatidylcholine species due to liver-specific LPLAT10 overexpression affect the pancreas and increase glucose-stimulated insulin secretion. Our findings highlight LPLAT10 as a potential novel therapeutic target for T2DM.

Abstract
Hypoxia inducible factor-1α (HIF-1α) is a crucial therapeutic target in various diseases, including cancer and fibrosis. We previously demonstrated that transfection with double-stranded RNA (dsRNA), including polyI:C and the dsRNA genome of mammalian orthoreovirus, resulted in significant reduction in HIF-1α protein levels in cultured cells; however, it remained to be elucidated how dsRNA induced down-regulation of HIF-1α protein levels. In this study, we examined the mechanism of dsRNA-mediated down-regulation of HIF-1α protein levels. We found that among the various cellular factors involved in dsRNA-mediated innate immunity, knockdown and knockout of protein kinase R (PKR) significantly restored HIF-1α protein levels in dsRNA-transfected cells, indicating that PKR was involved in dsRNA-mediated down-regulation of HIF-1α. Proteasome inhibitors significantly restored the HIF-1α protein levels in dsRNA-transfected cells. Ubiquitination levels of HIF-1α were increased by transfection with dsRNA. These findings indicated that degradation of HIF-1α in a ubiquitin-proteasome pathway was promoted in a PKR-dependent manner following dsRNA transfection. Expression of not only HIF-1α but also several proteins, including CDK4 and HER2, was down-regulated following dsRNA transfection. These data provide important clues for elucidation of the mechanism of dsRNA-mediated cellular toxicity, as well as for therapeutic application of dsRNA.

Abstract
Circulating tumor cells (CTCs) are present in the blood of cancer patients from the early stage of cancer development, and their presence has been correlated with patient prognosis and treatment responses. Accordingly, CTCs have been attracting attention as a novel biomarker for early detection of cancer and monitoring of treatment responses. However, since patients typically have only a few CTCs per milliliter of blood, development of an accurate and highly sensitive CTC detection method is crucial. We previously developed a CTC detection method using a novel conditionally replicating adenovirus (Ad) that expresses green fluorescence protein (GFP) in a tumor cell-specific manner by expressing the E1 gene using a tumor-specific human telomerase reverse transcriptase (hTERT) promoter (rAdF35-142T-GFP). CTCs were efficiently detected using rAdF35-142T-GFP, but GFP expression levels in the CTCs and production efficiencies of rAdF35-142T-GFP were relatively low. In this study, in order to overcome these problems, we developed four types of novel GFP-expressing conditionally replicating Ads and examined their ability to visualize CTCs in the blood samples of lung cancer patients. Among the four types of novel recombinant Ads, the novel conditionally replicating Ad containing the 2A peptide and the GFP gene downstream of the E1A gene and the adenovirus death protein (ADP) gene in the E3 region (rAdF35-E1-2A-GFP-ADP) mediated the highest number of GFP-positive cells in the human cultured tumor cell lines. Titers of rAdF35-E1-2A-GFP-ADP were significantly higher (about 4-fold) than those of rAdF35-142T-GFP. rAdF35-E1-2A-GFP-ADP and rAdF35-142T-GFP efficiently detected CTCs in the blood of lung cancer patients at similar levels. GFP+/CD45- cells (CTCs) were found in 10 of 17 patients (58.8%) for both types of recombinant Ads.

Abstract
Non-alcoholic liver disease (NAFLD) is a condition caused by excessive fat accumulation in the liver and developed via multiple pathways. miR-27b has been suggested to play crucial roles in the development of NAFLD, assuming via targeting genes involved in lipid catabolism and anabolism. However, other pathways regulated by miR-27b are largely unknown. Here we show that lipid accumulation was induced in miR-27b-transfected human and mouse hepatic cells and that knockdowns of three miR-27b-target genes, β-1,4-galactosyltransferase 3 (B4GALT3), matrix AAA peptidase interacting protein 1 (MAIP1) and PH domain and leucine rich repeat protein phosphatase 2 (PHLPP2), induced lipid accumulation. We also show that B4GALT3 and MAIP1 were direct targets of miR-27b and overexpression of MAIP1 ameliorated miR-27b-induced lipid accumulation. In addition, we show that hepatic Maip1 expression declined in mice fed a high-fat diet, suggesting the involvement of decreased Maip1 expression in the condition of fatty liver. Overall, we identified MAIP1/miR-27b axis as a mediator of hepatic lipid accumulation, a potential therapeutic target for NAFLD.

Abstract
BACKGROUND/AIM Oncolytic adenoviruses (Ads) (OAds) are gaining attention as an effective remedy for pancreatic cancer. Most OAds are based on human Ad serotype 5 (Ad5) (OAd5); however, two major drawbacks of OAd5 have been reported. Expression of coxsackievirus-adenovirus receptor, a primary infection receptor of Ad5, is often decreased on malignant tumor cells, including pancreatic cancers. More than 60% of adults have neutralizing antibodies against Ad5. Previously, we developed an OAd composed of Ad serotype 35 (Ad35) (OAd35). Ad35 recognizes CD46, which is often up-regulated on pancreatic cancers. In addition, only 20% or fewer adults have anti-Ad35 neutralizing antibodies. MATERIALS AND METHODS We examined the tumor cell lysis activities of OAd35 in the four human pancreatic cancer cell lines in the presence and absence of human serum. The tumor growth suppression effects of OAd35 after local and systemic administration were evaluated in nude mice bearing human pancreatic tumors. RESULTS OAd35 showed higher levels of tumor cell lysis activities than OAd5 in the human pancreatic cancer cell lines AsPC-1 and BxPC-3. Although the in vitro tumor cell lysis activities of OAd5 against MIA PaCa-2 and PANC-1 cells were strongly attenuated in the presence of human serum, OAd35 mediated comparable levels of tumor cell lysis in the presence and absence of human serum. Systemic administration of OAd5 did not mediate significant growth inhibition against the subcutaneous BxPC-3 tumor. On the other hand, OAd35 significantly suppressed tumor growth. CONCLUSION OAd35 would be suitable as an alternative anticancer agent for pancreatic cancer.

Abstract
PEGylated liposomes (PEG-liposomes) are a promising drug delivery vehicle for tumor targeting because of their efficient tumor disposition profiles via the enhanced permeability and retention (EPR) effect. However, tumor targeting of PEG-liposomes, particularly their delivery inside the tumors, is often disturbed by physical barriers in the tumor, including tumor cells themselves, extracellular matrices, and interstitial pressures. In this study, B16 melanoma tumor-bearing mice were injected intravenously with oncolytic reovirus before administration of PEG-liposomes to enhance PEG-liposomes' tumor disposition. Three days after reovirus administration, significant expression of reovirus sigma 3 protein, elevation of apoptosis-related gene expression, and activation of caspase 3 in the tumors were found. Apoptotic cells were found inside the tumors. These data indicated that reovirus efficiently replicated in the tumors and induced apoptosis of tumor cells. The tumor disposition levels of PEG-liposomes were approximately doubled by reovirus pre-administration, compared with a PBS-pretreated group. PEG-liposomes were widely distributed in the tumors of reovirus-pretreated mice, whereas in the PBS-pretreated group, PEG-liposomes were found mainly around or inside the blood vessels in the tumors. Pre-treatment with reovirus also improved the tumor accumulation of PEG-liposomes in human pancreatic BxPC-3 tumors. 3D imaging analysis of whole BxPC-3 tumors demonstrated that pretreatment with reovirus led to the enhancement of PEG-liposome accumulation inside the tumors. Combination treatment with reovirus and paclitaxel-loaded PEG-liposomes (PTX-PEG-liposomes) significantly suppressed B16 tumor growth. These results provide important information for clinical use of combination therapy of reovirus and nanoparticle-based drug delivery system (DDS).

Abstract
This study aimed to clarify the real-world efficacy of sequential nivolumab for treating metastatic renal cancer after first-line molecular targeting therapy. Patients were divided into two groups (2014-2016 and 2017-2020) according to the year when they started primary treatment with molecular targeted drugs (MTDs). We compared the overall survival of patients and investigated a contributing factor for survival. The mean duration of overall survival was significantly longer in the 2017-2020 group (44.0 months) than in the 2014-2016 group (8.5 months). Univariate analysis showed that nivolumab treatment was a significant prognostic factor (P = .0021). Patients treated with nivolumab as second-line therapy had a significantly higher 5-year survival rate compared to that of other patients (70% vs 32%). In addition, the time from commencement of MTDs to switch to nivolumab was significantly shorter in the 2017-2020 group compared to the 2014-2016 group (8.94 vs 34.12 months, P = .03). In our study, cases with first-line MTDs had markedly prolonged outcomes after the 2017 guideline update, and sequential nivolumab with prompt switching to nivolumab was an important factor.

Oncolytic adenoviruses (OAds) are getting much attention as cancer immunotherapy agents. Almost all OAds are based on human adenovirus serotype 5 (Ad5) (OAd5). However, OAd5 has several drawbacks which possibly attenuate the anti-tumor effects of OAd5. More than 80% of adults have neutralizing antibodies against Ad5. The expression of coxsackievirus-adenovirus receptor (CAR), which is the primary infection receptor of Ad5, often declines on malignant tumor cells. Previously, we have developed a novel OAd fully composed of human adenovirus serotype 35 (Ad35) (OAd35) (Ono et al., Mol.Ther.Oncolytics, 2021). Only 20% or fewer adults have neutralizing antibodies against Ad35. Ad35 recognizes CD46, which is highly expressed on malignant tumor cells, as an infection receptor. OAd35 showed efficient tumor cell lysis activities in many types of tumor cells; however, the mechanism of anti-tumor effects of OAd35 remains to be fully evaluated. In this study, we examined the mechanism of anti-tumor effects of OAd35. Although OAd35 showed efficient tumor growth suppression at levels comparable to OAd5 following intratumoral administration in nude mice bearing H1299 human lung cancer xenografts, the genome copy numbers of OAd35 in the tumor were about 500-folds lower than those of OAd5 at 18 days after administration and were almost background levels. These data suggest that other mechanisms different from infection of tumor cells with OAd35 were involved in the anti-tumor effects of OAd35. Since previous studies reported that Ad35 efficiently activated innate immunity in natural killer (NK) cells, we examined whether OAd35-mediated activation of NK cells contributed to the anti-tumor effects of OAd35. Intratumoral administration of OAd35 resulted in efficient infiltration and activation of NK cells in H1299 tumors. In contrast, OAd5 did not apparently induce the infiltration and activation of NK cells in the tumors. OAd35-mediated activation and infiltration of NK cells were also found in B16 tumor-bearing immunocompetent mice. Next, in order to examine the roles of NK cells in the anti-tumor effects of OAd35, NK cells were depleted by intravenous injection of anti-GM1 antibody in nude mice, followed by intratumoral administration of OAd35. The depletion of NK cells significantly attenuated the anti-tumor effects of OAd35 on H1299 tumors. Furthermore, pretreatment with anti-GM1 antibody significantly increased the genome copy numbers of OAd35 in the tumor, suggesting that activated NK cells removed the OAd35-infected tumor cells. This study demonstrated that OAd35 significantly activated NK cells following intratumoral administration and that activated NK cells efficiently removed the tumor cells, leading to efficient tumor growth suppression.

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
Conventional imaging techniques are available for clinical identification of tumor sites. However, detecting metastatic tumor cells that are spreading from primary tumor sites using conventional imaging techniques remains difficult. In contrast, fluorescence‐based labeling systems are useful tools for detecting tumor cells at the single‐cell level in cancer research. The ability to detect fluorescent‐labeled tumor cells enables investigations of the biodistribution of tumor cells for the diagnosis and treatment of cancer. For example, the presence of fluorescent tumor cells in the peripheral blood of cancer patients is a predictive biomarker for early diagnosis of distant metastasis. The elimination of fluorescent tumor cells without damaging normal tissues is ideal for minimally invasive treatment of cancer. To capture fluorescent tumor cells within normal tissues, however, tumor‐specific activated target molecules are needed. This review focuses on recent advances in tumor‐targeted fluorescence labeling systems, in which indirect reporter labeling using tumor‐specific promoters is applied to fluorescence labeling of tumor cells for the diagnosis and treatment of cancer. Telomerase promoter‐dependent fluorescence labeling using replication‐competent viral vectors produces fluorescent proteins that can be used to detect and eliminate telomerase‐positive tumor cells. Tissue‐specific promoter‐dependent fluorescence labeling enables identification of specific tumor cells. Vimentin promoter‐dependent fluorescence labeling is a useful tool for identifying tumor cells that undergo epithelial–mesenchymal transition (EMT). The evaluation of tumor cells undergoing EMT is important for accurately assessing metastatic potential. Thus, tumor‐targeted fluorescence labeling systems represent novel platforms that enable the capture of tumor cells for the diagnosis and treatment of cancer.

Abstract
Replication-incompetent adenovirus (Ad) vectors have been widely used as gene delivery vehicles in both gene therapy studies and basic studies for gene function analysis due to their highly advantageous properties, which include high transduction efficiencies, relatively large capacities for transgenes, and high titer production. In addition, Ad vectors induce moderate levels of innate immunity and have relatively high thermostability, making them very attractive as potential vaccine vectors. Accordingly, it is anticipated that Ad vectors will be used in vaccines for the prevention of infectious diseases, including Ebola virus disease and acquired immune deficiency syndrome (AIDS). Much attention is currently focused on the potential use of an Ad vector vaccine for coronavirus disease 2019 (COVID-19). In this review, we describe the basic properties of an Ad vector, Ad vector-induced innate immunity and immune responses to Ad vector-produced transgene products. Development of novel Ad vectors which can overcome the drawbacks of conventional Ad vector vaccines and clinical application of Ad vector vaccines to several infectious diseases are also discussed.

Abstract
Oncolytic viruses, which mediate tumor cell-specific infection, resulting in efficient tumor cell killing, have attracted much attention as a novel class of anti-cancer biopharmaceutical agents. Cancer-associated fibroblasts (CAFs) are an important component of the tumor microenvironment that strongly supports the growth, survival, and metastasis of tumor cells, suggesting that CAFs would have influence to the antitumor effects of oncolytic viruses; however, it remains to be fully evaluated whether oncolytic viruses affect the viabilities and properties of CAFs following treatment. Oncolytic reovirus, which is a non-enveloped virus that contains 10-segmented double-stranded RNA genome, shows efficient tumor cell lysis without apparent cytotoxicity to normal cells and has been tested worldwide in clinical trials against various types of tumors. In this study, we demonstrated that reovirus exhibited cytotoxicity against mouse primary CAFs isolated from subcutaneous tumors, but not against tail-tip fibroblasts. Infection with reovirus resulted in activation of caspase 3 and up-regulation of apoptosis-related gene expression, indicating that reovirus induced apoptosis of mouse primary CAFs. Intratumoral administration of reovirus induced apoptosis of mouse CAFs in the tumor. Taken together, these results indicate that reovirus has the potential to mediate antitumor effects by killing not only cancer cells but also CAFs.

Abstract
Human induced pluripotent stem (hiPS) cells are feasible materials for studying the biological mechanisms underlying human embryogenesis. In early embryogenesis, definitive endoderm and mesoderm are differentiated from their common precursor, mesendoderm. Bone morphogenetic protein (BMP) signaling is responsible for regulating mesendoderm and mesoderm formation. Micro RNAs (miRNAs), short non-coding RNAs, broadly regulate biological processes via post-transcriptional repression. The expression of miR-27b, which is enriched in somatic cells, has been reported to increase through definitive endoderm and hepatic differentiation, but little is known about how miR-27b acts during early differentiation. Here, we used miR-27b-inducible hiPS cells to investigate the roles of miR-27b in the undifferentiated and early-differentiated stages. In undifferentiated hiPS cells, miR-27b suppressed the expression of pluripotency markers [alkaline phosphatase (AP) and nanog homeobox (NANOG)] and cell proliferation. Once differentiation began, miR-27b expression repressed phosphorylated SMAD1/5, the mediators of the BMP signaling, throughout definitive endoderm differentiation. Consistent with the above findings, miR-27b overexpression downregulated BMP-induced mesendodermal marker genes [Brachyury, mix paired-like homeobox 1 (MIXL1) and eomesodermin (EOMES)], suggesting that miR-27b had an inhibitory effect on early differentiation. Collectively, our findings revealed a novel antagonistic role of miR-27b in the BMP signaling pathway in the early differentiation of hiPS cells.

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
OBJECTIVE To compare the surgical outcomes of laparoscopic sacrocolpopexy for pelvic organ prolapse between a group in which only sutures were used (standard method), and a group in which a combination of tackers and sutures were used (tacker combination method). METHODS A total of 77 patients who underwent laparoscopic sacrocolpopexys from June 2016 to October 2019 were divided into a suture group (36 patients) and a suture + tacker group (41 patients). We retrospectively compared operation time, amount of blood loss, postoperative length of hospital stay, incidence of perioperative complications and anatomical cure rate 1 year after surgery. Lower urinary tract symptoms were evaluated using symptom questionnaires and objective parameters. RESULTS Operation time in the suture + tacker group was shorter (104.9 ± 27.0 vs 147.5 ± 33.7 min; P < 0.0001). The incidence of perioperative complications in the suture group and the suture + tacker group was 2.8% and 2.4%, respectively (P = 0.9409). Anatomical cure rates at 1 year after surgery were 94.4% and 100%, respectively (P = 0.2153). Both groups showed significant improvement after 1 year for International Prostate Symptom Score total and quality of life score, Overactive Bladder Symptom Score total score, voided volume, maximum urinary flow rate and post-void residual. [Corrections added on 7 September 2021 after first online publication: the first two P-values have been updated.] CONCLUSIONS: The combined use of sutures and tackers in laparoscopic sacrocolpopexy simplifies the procedure and translates into shorter operation time. Surgical outcomes at 1 year and improvement of lower urinary tract symptoms are similar regardless of the technique.

Abstract
BACKGROUND/AIM Oncolytic reovirus, which is a non-enveloped virus possessing a 10-segmented double-stranded RNA genome, has been anticipated as a novel class of antitumor agent. Hepatocellular carcinoma (HCC) is considered to be a target suitable for reovirus-mediated virotherapy. Transforming growth factor (TGF)-β plays an important role in the pathogenesis of HCC. TGF-β-signaling inhibitors have proceeded to clinical trials as potential antitumor agents for HCC. On the other hand, TGF-β is involved in induction of expression of cathepsins B and L, which are important for reovirus infection. It remains to be examined whether TGF-β signaling inhibitors affect reovirus-mediated lysis of HCC cells. The aim of this study was to evaluate the effects of TGF-β-signaling inhibitors on tumor cell lysis efficiency of reovirus in human HCC cells. MATERIALS AND METHODS Reovirus was added to four types of human HCC cell lines pretreated with one of three TGF-β type I receptor inhibitors: SB431542, A-83-01, or galunisertib (LY2157299). Cell viability, virus genome copy numbers, and virus protein expression were evaluated following reovirus infection. RESULTS SB431542 significantly inhibited reovirus-mediated killing of human HCC cell lines, while A-83-01 and galunisertib did not inhibit. CONCLUSION These data indicate that SB431542 inhibited reovirus-mediated lysis of human HCC cells in a TGF-β signaling-independent manner.

Abstract
Human adenoviruses (Ads), common pathogens that cause upper respiratory and gastrointestinal infections, are blocked by neutralizing antibodies (nAbs). However, Ads are not fully eliminated even in hosts with nAbs. In this study, we assessed the infectivity of progeny Ad serotype 5 (Ad5) in the presence of nAb. The infectivity of Ad5 was evaluated according to the expression of the Ad genome and reporter gene. Infection by wild-type Ad5 and Ad5 vector continued to increase until 3 days after infection even in the presence of nAb. We established an assay for determining the infection levels of progeny Ad5 using a sorting system with magnetic beads and observed little difference in progeny Ad5 counts in the presence and absence of nAb 1 day after infection. Moreover, progeny Ad5 in the presence of nAb more effectively infected coxsackievirus and adenovirus receptor (CAR)-positive cells than CAR-negative cells. We investigated the function of fiber proteins, which are the binding partners of CAR, during secondary infection, observing that fibre proteins spread from infected cells to adjacent cells in a CAR-dependent manner. In conclusion, this study revealed that progeny Ad5 could infect cells even in the presence of nAb, differing from the common features of the Ad5 infection cycle. Our findings may be useful for developing new therapeutic agents against Ad infection.

Abstract
Genome-wide association studies have identified more than 300 loci associated with type 2 diabetes mellitus; however, the mechanisms underlying their role in type 2 diabetes mellitus susceptibility remain largely unknown. Zinc finger AN1-type domain 3 (ZFAND3), known as testis-expressed sequence 27, is a type 2 diabetes mellitus-susceptibility gene. Limited information is available regarding the physiological role of ZFAND3 in vivo. This study aimed to investigate the association between ZFAND3 and type 2 diabetes mellitus. ZFAND3 was significantly upregulated in the liver of diabetic mice compared to wild-type mice. To overexpress ZFAND3, we generated a ZFAND3-expressing adenovirus (Ad) vector using an improved Ad vector exhibiting significantly lower hepatotoxicity (Ad-ZFAND3). Glucose tolerance was significantly improved in Ad-ZFAND3-treated mice compared to the control Ad-treated mice. ZFAND3 overexpression in the mouse liver also improved insulin resistance. Furthermore, gluconeogenic gene expression was significantly lower in primary mouse hepatocytes transduced with Ad-ZFAND3 than those transduced with the control Ad vector. The present results suggest that ZFAND3 improves glucose tolerance by improving insulin resistance and suppressing gluconeogenesis, serving as a potential novel therapeutic target for type 2 diabetes mellitus.

Abstract
The intestinal mucosa plays an important role as an immune barrier due to its continual exposure to invading pathogens, including viruses. It is thus highly important to evaluate virus infection profiles in the intestinal mucosa for prevention of virus infection and development of antivirus medicines; however, only a few enterocyte lines are available as in vitro intestinal models for the evaluation of virus infection. In this study, we evaluated profiles of infection and innate immune responses following infection with a mammalian orthoreovirus (hereafter reovirus), which has often been used as a tractable model for studies of viral pathogenesis, in human iPS cell-derived small intestinal epithelial-like cell (hiPS-SIEC) monolayers and cells of a human colon adenocarcinoma cell line, Caco-2. The levels of reovirus infection were similar between hiPS-SIEC and Caco-2 cell monolayers, which are often used as an intestinal model, after apical and basolateral infection. In hiPS-SIEC monolayers, more efficient replication of the virus genome was observed following basolateral infection than apical infection, while apical infection resulted in higher levels of virus protein expression and progeny virus production than basolateral infection. Reovirus significantly induced innate immune responses, including expression of type I and III interferons (IFNs), in hiPS-SIEC monolayers more efficiently than Caco-2 cells. Higher levels of type I and III interferon (IFN) expression were found in hiPS-SIEC monolayers following apical infection than basolateral infection. These results suggested that hiPS-SIECs are a promising in vitro model for the evaluation of virus infection.

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
Oncolytic adenoviruses (OAds) are among the most promising oncolytic viruses. Almost all oncolytic adenoviruses are composed of human adenovirus serotype 5 (Ad5) (OAd5). However, expression of the primary infection receptor for Ad5, coxsackievirus-adenovirus receptor (CAR), often declines on malignant tumor cells, resulting in inefficient infection in CAR-negative tumor cells. In addition, at least 80% of adults have neutralizing antibodies against Ad5. In this study, we developed a novel OAd fully composed of OAd35. OAd35 recognizes CD46, which is ubiquitously expressed on almost all human cells and is often upregulated on malignant tumor cells, as an infection receptor. Moreover, 20% or fewer adults have neutralizing antibodies against Ad35. OAd35 mediated efficient cell lysis activities at levels similar to OAd5 in CAR-positive tumor cells, while OAd35 showed higher levels of cell lysis activities than OAd5 in CAR-negative tumor cells. Anti-Ad5 serum significantly inhibited in vitro tumor cell lysis activities of OAd5, whereas OAd35 exhibited comparable levels of in vitro tumor cell lysis activities in the presence of anti-Ad5 and naive serum. OAd35 significantly suppressed growth of the subcutaneous CAR-positive and CAR-negative tumors following intratumoral administration. These results indicated that OAd35 is a promising alternative oncolytic virus for OAd5.

Abstract
BACKGROUND Surgical treatments for renal cell carcinoma reduces kidney volume to some degree and may derive postsurgical chronic kidney disease. We made a new marker for postoperative renal function using CT volumetry. To determine the impact of various parameters including this marker, we observed pre- and postsurgical renal function of experienced cases. METHODS From 2004 to 2014, we underwent total or partial nephrectomy for 181 patients with renal carcinoma in a single institution. Of the total, 138 cases with presurgical CT volumetry were included in this study. We evaluated parameters for assessments of peri- and postoperative renal function including age, gender, serum creatinine, eGFR, performed surgery, pathology, estimated residual kidney volume and associated disease. Presence or absence of acute kidney injury (AKI) and chronic kidney disease (CKD) were also evaluated before, immediately after and 5 years after surgery. RESULTS Multiple logistic regression analysis identified AKI, preoperative eGFR and estimated residual kidney volume as significant prognostic factors for the postoperative CKD. Moreover, cases with triple positive of these factors suffer postoperative CKD more significantly than those with one or two positives. CONCLUSION Using these predictive factors, we may determine patients with high risk for CKD who require an early intervention of renal protective treatment.

Abstract
IL-10 is an immune regulatory cytokine and its genetic defect leads to gastrointestinal inflammation in humans and mice. Moreover, the IL-23/Th17 axis is known to be involved in these inflammatory disorders. IL-17A, a representative cytokine produced by Th17 cells, has an important role for the pathological process of inflammatory diseases. However, the precise function of IL-17A in inflammatory bowel disease (IBD) remains controversial. In this study, we evaluated the effect of IL-17A on colitis in IL-10-deficient (Il10−/−) mice. Mice lacking both IL-10 and IL-17A (Il10−/−Il17a−/−) suffered from fatal wasting and manifested more severe colitis compared with Il10−/−Il17a+/− mice. Moreover, we found that CD11b+Gr-1+ myeloid-derived suppressor cells (MDSCs) accumulated in the bone marrow, spleen and peripheral blood of Il10−/−Il17a−/− mice. These MDSCs highly expressed inducible nitric oxide synthase (iNOS) (Nos2) and suppressed the T-cell response in vitro in a NOS-dependent manner. In correlation with these effects, the concentration of nitric oxide was elevated in the serum of Il10−/−Il17a−/− mice. Surprisingly, the severe colitis observed in Il10−/−Il17a−/− mice was ameliorated in Il10−/−Il17a−/−Nos2−/− mice. Our findings suggest that IL-17A plays suppressive roles against spontaneous colitis in Il10−/− mice in an iNOS-dependent manner and inhibits MDSC differentiation and/or proliferation.

Abstract
BACKGROUND Arming of an oncolytic adenovirus (OAd) by inserting expression cassettes of therapeutic transgenes into the OAd genome is a promising approach to enhance the therapeutic effects of an OAd. Ideally, this approach would simultaneously promote the replication of an OAd in tumor cells and transgene product-mediated antitumor effects by expressing therapeutic transgenes. We previously demonstrated that knockdown of cullin 4A (CUL4A), which is an E3 ubiquitin ligase, significantly promoted adenovirus replication by increasing the c-JUN protein level. In addition, previous studies reported that CUL4A was highly expressed in various types of tumor, and was involved in tumor growth and metastasis. MATERIALS AND METHODS In this study, we developed a novel OAd expressing a short-hairpin RNA (shRNA) against CUL4A (OAd-shCUL4A). RESULTS OAd-shCUL4 mediated higher levels of cytotoxic effects on various types of human tumor cell than a conventional OAd. Higher levels of OAd genome copy numbers were found in the tumor cells for OAd-shCUL4A, compared with a conventional OAd. CONCLUSION OAd-shCUL4A showed efficient antitumor effects by both enhancing OAd replication and inhibiting tumor cell growth.

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.

Abstract
Myeloid-derived suppressor cells (MDSCs) are immunosuppressive myeloid cells found in patients with cancer and in mouse tumor models. They suppress anti-tumor immunity, resulting in the promotion of tumor growth. The relationship between nutrition and cancer has recently been reported by several research groups. Tumor cells rely on glutaminolysis, in which glutamine is metabolized into glutamate for energy production, and hence, glutamate levels are elevated in tumor-bearing hosts. However, the mechanism of regulation of tumor progression by glutamate still remains unclear. In this study, we found that the metabotropic glutamate receptor (mGluR) 2/3 was expressed on MDSCs, and an mGluR2/3 antagonist LY341495 attenuated the immunosuppressive activity of MDSCs. Furthermore, we observed that LY341495 treatment inhibited B16-F10 melanoma growth in vivo. Taken together, our data suggest that glutamate signaling promotes tumor growth by increasing the potency of immune suppression.

Abstract
Instead of liver transplantation or liver-directed gene therapy, genetic liver diseases are expected to be treated effectively using liver tissue engineering technology. Hepatocyte-like cells (HLCs) generated from human-induced pluripotent stem (iPS) cells are an attractive unlimited cell source for liver-like tissue engineering. In this study, we attempted to show the effectiveness of human iPS cell–based liver-like tissue engineering at an extrahepatic site for treatment of hemophilia B, also called factor IX (FIX) deficiency. HLCs were transplanted under the kidney capsule where the transplanted cells could be efficiently engrafted. Ten weeks after the transplantation, human albumin (253 μg/mL) and α-1 antitrypsin (1.2 μg/mL) could be detected in the serum of transplanted mice. HLCs were transplanted under the kidney capsule of FIX-deficient mice. The clotting activities in the transplanted mice were approximately 5% of those in wild-type mice. The bleeding time in transplanted mice was shorter than that in the nontransplanted mice. Taken together, these results indicate the success in generating functional liver-like tissues under the kidney capsule by using human iPS cell–derived HLCs. We also demonstrated that the human iPS cell–based liver-like tissue engineering technology would be an effective treatment of genetic liver disease including hemophilia B.

Abstract
Introduction We presented a rare case of caval lobular capillary hemangioma. Case presentation A 66‐year‐old female visited our department complaint with shadow defect in vena cava of right renal hilum appeared on computed tomography for periodically checking 3 years after radical hysterectomy with bilateral ovariectomy. Abdominal computed tomography identified a shadow defect of 35 mm in diameter in the inferior vena cava continuing posteriorly to a 35 mm mass of retroperitoneum. During the total removal of this lesion, we identified the lesion was connected to right ovarian vein. The specimen consisted of microcapillaries which formed reticular structure. Immunostaining of specimens identified positive CD31, CD34, and Factor 8 in all cells. Ki67 antibody was positive at 2–3% of all cells. These findings suggested the tumor was intravenous lobular papillary hemangioma. Conclusion This is the first report of intravenous lobular papillary hemangioma originated from right ovarian vein and extended to inferior vena cava.

Abstract
The small intestine plays an important role in the absorption and metabolism of oral drugs. In the current evaluation system, it is difficult to predict the precise absorption and metabolism of oral drugs. In this study, we generated small intestinal epithelial-like cells from human induced pluripotent stem cells (hiPS-SIECs), which could be applied to drug absorption and metabolism studies. The small intestinal epithelial-like cells were efficiently generated from human induced pluripotent stem cell by treatment with WNT3A, R-spondin 3, Noggin, EGF, IGF-1, SB202190, and dexamethasone. The gene expression levels of small intestinal epithelial cell (SIEC) markers were similar between the hiPS-SIECs and human adult small intestine. Importantly, the gene expression levels of colonic epithelial cell markers in the hiPS-SIECs were much lower than those in human adult colon. The hiPS-SIECs generated by our protocol exerted various SIEC functions. In conclusion, the hiPS-SIECs can be utilized for evaluation of drug absorption and metabolism.

Abstract
In recent times, oncolytic viruses expressing an extraneous gene have attracted great interest; in fact, they have been engaged in multiple applications, such as medicine for cancer. Our group made an oncolytic adenovirus, namely, OBP-301, for use in treating solid cancers and press clinical trial to get approval for a pharmaceutical product. In this study, we applied a flow cytometry-based method to determine the titer of adenoviruses expressing an extraneous gene as well as assess their quality. We considered using the green fluorescent protein (GFP)50 titer as a measure of viral quality. The GFP50 titer (GFP50/mL) is the viral load required to render the HeLa S3 cell line 50% GFP-positive by analysing flow cytometry data. We measured the GFP50 titers for three types of recombinant adenoviruses (OBP-401, OBP-1101, and OBP-1106). We compared GFP50/mL and tissue culture infectious dose (TCID50/mL), a conventional titration index, and found that these titers showed a linear correlation, with a correlation coefficient of >0.9. Moreover, GFP50/mL showed high repetitive accuracy. We expect this flow cytometry-based method to be useful in case of clinically relevant viruses expressing an extraneous gene, in particular, to control viral quality.

Abstract
Hepatocyte-like cells differentiated from human iPS cells are expected to be utilized in pharmaceutical research and regenerative medicine. Recently, various culture methods for human iPS cell maintenance have been developed. However, it is not well known whether human iPS cell maintenance method affects hepatic differentiation potency. In this study, we cultured human iPS cells using four maintenance methods: ReproStem medium with feeder cells (mouse embryonic fibroblasts), AK02N medium with iMatrix-511 (E8 fragments of laminin511), Essential 8 medium with Vitronectin N (N-terminal domain of vitronectin), TeSR-E8 medium with Vitronectin XF (xeno-free vitronectin). Then, these human iPS cells were differentiated into the hepatocyte-like cells. Interestingly, the gene expression levels of definitive endoderm markers in the definitive endoderm cells generated from human iPS cells cultured with ReproStem or TeSR-E8 medium were higher than those in other groups. The gene expression level of foregut marker, HHEX, in the definitive endoderm cells generated from human iPS cells cultured with ReproStem medium was higher than that in other groups. Consistently, the expression levels of hepatocyte markers, albumin and urea secretion capacity, and CYP3A4 activity in the hepatocyte-like cells generated from human iPS cells cultured with ReproStem medium were higher than those in the other groups. Our data indicated that the most suitable human iPS cell maintenance method for efficient hepatic differentiation was the on-feeder method which uses mouse embryonic fibroblasts, but not feeder-free methods. In conclusion, human iPS cell maintenance method largely affects hepatic differentiation potency.

Abstract
Anti-anaplastic lymphoma kinase (ALK)-targeted therapy dramatically improves therapeutic responses in patients with ALK-rearranged lung adenocarcinoma (Ad-LC). A few cases of squamous cell lung carcinoma (Sq-LC) with ALK rearrangement have been reported; however, the clinicopathological features and clinical outcomes following treatment with ALK inhibitors are unknown. We addressed this in the present study by retrospectively comparing the clinical characteristics of five patients with ALK-rearranged Sq-LC with those of patients with ALK-rearranged Ad-LC and by evaluating representative cases of ALK inhibitor responders and non-responders. The prevalence of ALK rearrangement in Sq-LCs was 1.36%. Progression-free survival (PFS) after initial treatment with crizotinib was significantly shorter in Sq-LC than in Ad-LC with ALK rearrangement (p = 0.033). Two ALK rearrangements assayed by fluorescence in situ hybridization (FISH)-positive/immunohistochemistry-negative cases did not respond to crizotinb, and PFS decreased following alectinib treatment of ALK-rearranged Sq-LC (p = 0.045). A rebiopsy revealed that responders to ceritinib harbored the L1196M mutation, which causes resistance to other ALK inhibitors. However, non-responders were resistant to all ALK inhibitors, despite the presence of ALK rearrangement in FISH-positive circulating tumor cells and circulating free DNA and absence of the ALK inhibitor resistance mutation. These results indicate that ALK inhibitors remain a reasonable therapeutic option for ALK-rearranged Sq-LC patients who have worse outcomes than ALK-rearranged Ad-LC patients and that resistance mechanisms are heterogeneous. Additionally, oncologists should be aware of the possibility of ALK-rearranged Sq-LC based on clinicopathological features, and plan second-line therapeutic strategies based on rebiopsy results in order to improve patient outcome.

Abstract
Oncolytic reovirus, which possesses 10 segments of dsRNA genome, mediates antitumor effects via not only virus replication in a tumor cell-specific manner, but also activation of antitumor immunity; however, the mechanism(s) of reovirus-induced activation of antitumor immunity have not been fully elucidated. Recent studies have demonstrated that overcoming an immunosuppressive environment in tumor-bearing hosts is important to achieve efficient activation of antitumor immunity. Among the various types of cells involved in immunosuppression, it has been revealed that myeloid-derived suppressor cells (MDSCs) are significantly increased in tumor-bearing hosts and play crucial roles in the immunosuppression in tumor-bearing hosts. In this study, we examined whether reovirus inhibits the immunosuppressive activity of MDSCs, resulting in efficient activation of immune cells after in vivo administration. The results showed that splenic MDSCs recovered from PBS-treated tumor-bearing mice significantly suppressed the Ag-specific proliferation of CD8+ T cells. In contrast, the suppressive activity of MDSCs on T cell proliferation was significantly reduced after reovirus administration. Reovirus also inhibited the immunosuppressive activity of MDSCs in IFN-β promoter stimulator-1 knockout (KO) mice and in wild-type mice. In contrast, the immunosuppressive activity of MDSCs in TLR-3 KO mice was not significantly altered by reovirus treatment. The activation levels of CD4+ and CD8+ T cells were significantly lower in TLR3 KO mice than in wild-type mice after reovirus administration. These results indicate that reovirus inhibits the immunosuppressive activity of MDSCs in a TLR3, but not IFN-β promoter stimulator-1, signaling-dependent manner.

Abstract
Human induced pluripotent stem cell-derived hepatocyte-like cells (HLCs) are expected to be utilized in pharmaceutical research, including drug screening. However, the hepatocyte functions of the HLCs are still lower than those of human hepatocytes. Therefore, we attempted to improve the hepatocyte differentiation method by modulating the DNA epigenetic status. We first examined the expression profiles of the maintenance DNA methyltransferase (DNMT) 1 and the de novo DNMTs DNMT3A and DNMT3B, all of which are essential for mammalian development. Among these DNMTs, the expression levels of DNMT3B were significantly decreased during the hepatoblast differentiation. To accelerate the hepatoblast differentiation, a DNMT3B-selective inhibitor, nanaomycin A, was treated during the hepatoblast differentiation. The gene expression levels of hepatoblast markers (such as alpha-fetoprotein and hepatocyte nuclear factor 4 alpha) were increased by the nanaomycin A treatment. On the other hand, the gene expression levels of hepatoblast markers were decreased by DNMT3B overexpression. These results suggest that it might be possible to promote the hepatoblast differentiation by DNMT3B inhibition using nanaomycin A. Importantly, we also confirmed that the hepatocyte differentiation potency of nanaomycin A-treated hepatoblast-like cells was higher than that of dimethyl sulfoxide-treated hepatoblast-like cells. Our findings should assist in the future generation of functional HLCs for pharmaceutical research.

Abstract
Human iPS cell-derived hepatocyte-like cells are expected to be utilized in pharmaceutical research. However, the purity of high-functioning hepatocyte-like cells is not high enough. In particular, the purity of cytochrome P450 3A4 (CYP3A4), which is a representative hepatic drug-metabolizing enzyme, positive cells is still quite low (approximately 20%). To address this problem, we established the CYP3A4-NeoR-EGFP transgenic reporter human iPS cell line (CYP3A4-NeoR-EGFP iPS cells) by using genome editing technology. The CYP3A4-NeoR-EGFP iPS cells were differentiated into hepatocyte-like cells, and then the hepatocyte-like cells were treated with neomycin to concentrate the hepatocyte-like cells which strongly express CYP3A4. After the neomycin treatment, the percentage of CYP3A4-positive cells was higher than 80%. The gene expression levels of various drug-metabolizing enzymes, transporters, and hepatic transcription factors were significantly enhanced by neomycin treatment. In addition, the CYP1A2, 2C19, 2D6, and 3A4 activities and biliary excretion capacities were significantly increased by neomycin treatment. We also confirmed that the detection sensitivity of drug-inducing hepatotoxicity was enhanced by neomycin treatment. We succeeded in obtaining human iPS cell-derived hepatocyte-like cells that highly express CYP3A4 at high purity. We believe that our high-purity and high-functioning hepatocyte-like cells could be used to evaluate the risk of drug candidates.

Abstract
Carcinosarcomas of the urinary bladder are rare biphasic neoplasms, consisting of both malignant epithelial and malignant mesenchymal components, and the prognosis of this tumor is unfavorable in most patients with even possibility of resection of disease. A 77-year-old male with a history of transurethral resection (TUR) of urothelial carcinoma (UC) of the bladder and adjuvant intravesical chemotherapy with pirarubicin 10 years ago revisited our department with a gross hematuria. Cystoscopy demonstrated an approximately 2.5 cm nonpapillary tumor on the right wall of the bladder. Pelvic MRI showed the tumor without extending the base of the bladder wall. The tumor could be completely removed with TUR. The malignant epithelial elements consisted of high-grade UC and the majority of mesenchymal components were fibrosarcomatous differentiation based on immunohistochemical studies. The tumor could be pathologically also suspected to be an early stage on TUR specimens. Although he has received no additional intervention due to the occurrence of myocardial infarction at three weeks after the TUR, he has been alive with no evidence of recurrence of the disease 27 months after the TUR. Some early stages of bladder carcinosarcoma might have a favorable prognosis without aggressive treatments.

Abstract
The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) 9 system is now widely used as a genome editing tool. CRISPR-associated endonuclease in Prevotella and Francisella 1 (Cpf1) is a recently discovered Cas endonuclease that is designable and highly specific with efficiencies comparable to those of Cas9. Here we generated the adenovirus (Ad) vector carrying an Acidaminococcus sp. Cpf1 (AsCpf1) expression cassette (Ad-AsCpf1) for the first time. Ad-AsCpf1 was applied to primary human hepatocytes prepared from humanized mice with chimeric liver in combination with the Ad vector expressing the guide RNA (gRNA) directed to the Adeno-associated virus integration site 1 (AAVS1) region. The mutation rates were estimated by T7 endonuclease I assay around 12% of insertion/deletion (indel). Furthermore, the transduced human hepatocytes were viable (ca. 60%) at two weeks post transduction. These observations suggest that the Ad vector-mediated delivery of the CRISPR/AsCpf1 system provides a useful tool for genome manipulation of human hepatocytes.

Abstract
Telomerase-specific replication-competent adenoviruses (Ads), i.e., TRADs, which possess an E1 gene expression cassette driven by the human telomerase reverse transcriptase promoter, are promising agents for cancer treatment. However, even though oncolytic Ads, including TRAD, are intratumorally administered, they are disseminated from the tumor to systemic circulation, causing concern about oncolytic Ad-mediated hepatotoxicity (due mainly to leaky expression of Ad genes in liver). We reported that inhibition of nuclear factor-κB (NF-κB) leads to the suppression of replication-incompetent Ad vector-mediated hepatotoxicity via reduction of the leaky expression of Ad genes in liver. Here, to develop a TRAD with an improved safety profile, we designed a TRAD that carries a liver-specific promoter-driven dominant-negative IκBα (DNIκBα) expression cassette (TRAD-DNIκBα). Compared with a conventional TRAD, TRAD-DNIκBα showed hepatocyte-specific inhibition of NF-κB signaling and significantly reduced Ad gene expression and replication in the normal human hepatocyte cell line. TRAD-induced hepatotoxicity was largely suppressed in mice following intravenous administration of TRAD-DNIκBα. However, the replication profiles and oncolytic activities of TRAD-DNIκBα were comparable with those of the conventional TRAD in human non-hepatic tumor cells. These results indicate that oncolytic Ads containing the liver-specific DNIκBα expression cassette have improved safety profiles without inhibiting oncolytic activities.

Abstract
Circulating tumor cells (CTC) are newly discovered biomarkers of cancers. Although many systems detect CTC, a gold standard has not yet been established. We analyzed CTC in uterine cervical cancer patients using an advanced version of conditionally replicative adenovirus targeting telomerase-positive cells, which was enabled to infect coxsackievirus-adenovirus receptor-negative cells and to reduce false-positive signals in myeloid cells. Blood samples from cervical cancer patients were hemolyzed and infected with the virus and then labeled with fluorescent anti-CD45 and anti-pan cytokeratin antibodies. GFP (+)/CD45 (-) cells were isolated and subjected to whole-genome amplification followed by polymerase chain reaction analysis of human papillomavirus (HPV) DNA. CTC were detected in 6 of 23 patients with cervical cancers (26.0%). Expression of CTC did not correlate with the stage of cancer or other clinicopathological factors. In 5 of the 6 CTC-positive cases, the same subtype of HPV DNA as that of the corresponding primary lesion was detected, indicating that the CTC originated from HPV-infected cancer cells. These CTC were all negative for cytokeratins. The CTC detected by our system were genetically confirmed. CTC derived from uterine cervical cancers had lost epithelial characteristics, indicating that epithelial marker-dependent systems do not have the capacity to detect these cells in cervical cancer patients.

Abstract
Recently, it has been reported that human hepatocyte-like cells can be generated from fibroblasts by direct reprogramming technology. However, the conversion efficiency of human induced hepatocyte-like cells (hiHeps) is not high enough. In addition, comparative analysis with the existing models of hepatocytes, such as human iPS cell-derived hepatocyte-like cells and primary human hepatocytes, has not been sufficiently carried out. In this study, we screened hepatic transcription factors for efficient direct hepatic reprogramming and compared hepatic functions between hiHeps and other existing hepatocyte models. We found that human fibroblasts were efficiently converted into hiHeps by using a combination of ATF5, PROX1, FOXA2, FOXA3, and HNF4A (albumin+/alpha-1 antitrypsin+ cells = 27%, asialoglycoprotein receptor 1+ cells = 22%). The CYP expression levels and CYP activities in hiHeps were higher than those in human iPS cell-derived hepatocyte-like cells, but lower than those in short-term (4 hr) cultured primary human hepatocytes and primary human hepatocytes collected immediately after thawing. These results suggested that functional hiHeps could be efficiently generated by ATF5, PROX1, FOXA2, FOXA3, and HNF4A transduction. We believe that hiHeps generated by our method will be useful for the drug-discovery activities such as hepatotoxicity screening and drug metabolism tests.

Abstract
Few current vaccines can establish antigen (Ag)-specific immune responses in both mucosal and systemic compartments. Therefore, development of vaccines providing defense against diverse infectious agents in both compartments is of high priority in global health. Intramuscular vaccination of an adenovirus vector (Adv) has been shown to induce Ag-specific cytotoxic T lymphocytes (CTLs) in both systemic and gut-mucosal compartments. We previously found that type I interferon (IFN) signaling is required for induction of gut-mucosal, but not systemic, CTLs following vaccination; however, the molecular mechanism involving type I IFN signaling remains unknown. Here, we found that T helper 17 (Th17)-polarizing cytokine expression was down-regulated in the inguinal lymph nodes (iLNs) of Ifnar2−/− mice, resulting in the reduction of Ag-specific Th17 cells in the iLNs and gut mucosa of the mice. We also found that prior transfer of Th17 cells reversed the decrease in the number of Ag-specific gut-mucosal CTLs in Ifnar2−/− mice following Adv vaccination. Additionally, prior transfer of Th17 cells into wild-type mice enhanced the induction of Ag-specific CTLs in the gut mucosa, but not in systemic compartments, suggesting a gut mucosa-specific mechanism where Th17 cells regulate the magnitude of vaccine-elicited Ag-specific CTL responses. These data suggest that Th17 cells translate systemic type I IFN signaling into a gut-mucosal CTL response following vaccination, which could promote the development of promising Adv vaccines capable of establishing both systemic and gut-mucosal protective immunity.

Abstract
Hepatocyte‐like cells (HLCs) differentiated from human induced pluripotent stem (iPS) cells are expected to be applied for regenerative medicine. In this study, we attempted to generate safe and therapeutically effective human iPS‐HLCs for hepatocyte transplantation. First, human iPS‐HLCs were generated from a human leukocyte antigen‐homozygous donor on the assumption that the allogenic transplantation might be carried out. Highly efficient hepatocyte differentiation was performed under a feeder‐free condition using human recombinant laminin 111, laminin 511, and type IV collagen. The percentage of asialoglycoprotein receptor 1‐positive cells was greater than 80%, while the percentage of residual undifferentiated cells was approximately 0.003%. In addition, no teratoma formation was observed even at 16 weeks after human iPS‐HLC transplantation. Furthermore, harmful genetic somatic single‐nucleotide substitutions were not observed during the hepatocyte differentiation process. We also developed a cryopreservation protocol for hepatoblast‐like cells without negatively affecting their hepatocyte differentiation potential by programming the freezing temperature. To evaluate the therapeutic potential of human iPS‐HLCs, these cells (1 × 106 cells/mouse) were intrasplenically transplanted into acute liver injury mice treated with 3 mL/kg CCl4 only once and chronic liver injury mice treated with 0.6 mL/kg CCl4 twice weekly for 8 weeks. By human iPS‐HLC transplantation, the survival rate of the acute liver injury mice was significantly increased and the liver fibrosis level of chronic liver injury mice was significantly decreased. Conclusion: We were able to generate safe and therapeutically effective human iPS‐HLCs for hepatocyte transplantation. (Hepatology Communications 2017;1:1058–1069)

Abstract
Genome editing research of human ES/iPS cells has been accelerated by clustered regularly interspaced short palindromic repeats/CRISPR-associated 9 (CRISPR/Cas9) and transcription activator-like effector nucleases (TALEN) technologies. However, the efficiency of biallelic genetic engineering in transcriptionally inactive genes is still low, unlike that in transcriptionally active genes. To enhance the biallelic homologous recombination efficiency in human ES/iPS cells, we performed screenings of accessorial genes and compounds. We found that RAD51 overexpression and valproic acid treatment enhanced biallelic-targeting efficiency in human ES/iPS cells regardless of the transcriptional activity of the targeted locus. Importantly, RAD51 overexpression and valproic acid treatment synergistically increased the biallelic homologous recombination efficiency. Our findings would facilitate genome editing study using human ES/iPS cells.

Abstract
The function of hepatocytes largely depends on their position in the liver lobule. Although the method of differentiating hepatocytes from human pluripotent stem cells has been largely improved over the past decade, there remains no technique for generating hepatocyte-like cells (HLCs) with zone-specific hepatic properties. In this study, we searched for the factors that promote acquisition of zone-specific properties of HLCs. Here, we identified that WNT7B and WNT8B secreted from hepatocytes and cholangiocytes play important roles in achieving perivenous zone-specific characteristics, such as the enhancement of glutamine secretion, citric acid cycle, cytochrome P450 (CYP) 1A2 metabolism, and CYP1A2 induction capacities. We also found that WNT inhibitory factor (WIF-1) secreted from cholangiocytes was necessary for achieving periportal zone-specific characteristics, such as the enhancement of urea secretion and gluconeogenesis capacities. Therefore, WNT signal modulators secreted from hepatocytes or cholangiocytes conferred zone-specific hepatic properties onto HLCs.

Abstract
Japanese patients with type 2 diabetes mellitus present a different responsiveness in terms of insulin secretion to glucose and body mass index (BMI) from other populations. The genetic background that predisposes Japanese individuals to type 2 diabetes mellitus is under study. Recent genetic studies demonstrated that the locus mapped in macrophage erythroblast attacher (MAEA) increases the susceptibility to type 2 diabetes mellitus in East Asians, including Japanese individuals. MAEA encodes a protein that plays a role in erythroblast enucleation and in the normal differentiation of erythroid cells and macrophages. However, the contribution of MAEA to type 2 diabetes mellitus remains unknown. In this study, to overexpress MAEA in the mouse liver and primary mouse hepatocytes, we generated a MAEA-expressing adenovirus (Ad) vector using a novel Ad vector exhibiting significantly lower hepatotoxicity (Ad-MAEA). Blood glucose and insulin levels in Ad-MAEA-treated mice were comparable to those in control Ad-treated mice. Primary mouse hepatocytes transduced with Ad-MAEA showed lower levels of expression of gluconeogenesis genes than those transduced with the control Ad vector. Hepatocyte nuclear factor-4α (HNF-4α) mRNA expression in primary mouse hepatocytes was also suppressed by MAEA overexpression. These results suggest that MAEA overexpression attenuates hepatic gluconeogenesis, which could potentially lead to improvement of type 2 diabetes mellitus.

Abstract
Reovirus induces tumor cell death efficiently and specifically, and thus is currently undergoing clinical testing as an anticancer agent. In the intracellular trafficking of reovirus, proteolytic disassembly of reovirus capsid-proteins and subsequent penetration of viral particles into the cytosol are crucial steps. Cathepsins B and L are largely responsible for the proteolytic disassembly of reovirus. Reovirus efficiently lyses tumor cells exhibiting relatively high activities of cathepsins B and L, while tumor cells with low activities of cathepsins B and L are often refractory to reovirus, probably due to inefficient endo/lysosomal escape. In this study, in order to enhance the tumor cell-killing efficiencies of reovirus by promoting endo/lysosomal escape, especially in reovirus-resistant tumor cells, reovirus was complexed with a cationic liposome transfection reagent. Reovirus alone and reovirus-cationic liposome complex (reoplex) exhibited similar levels of tumor cell-killing efficiencies in reovirus-susceptible tumor cells, while reoplex mediated more than 30% higher levels of tumor cell-killing activities in reovirus-resistant tumor cells than reovirus alone. Reoplex-mediated tumor cell death was efficiently induced in the tumor cells pretreated with cathepsin inhibitors. The mRNA levels of interferon (IFN)-β and apoptotic genes were significantly elevated following reoplex treatment. These results suggest that cationic liposomes efficiently promoted delivery of reovirus to the cytosol, leading to induction of apoptosis.

Abstract
The reported incidence rate of iatrogenic ureteral injury is 0.5 to 3% among abdominal surgery. We report a case of ureterouterine fistula after caesarean section. A 38-year-old woman visited our department with a complaint of urinary incontinence without dry time after caesarean section. Several examinations revealed right ureterouterine fistula.Ureteroneocystostomy using psoas hitch and hysterectomy was performed. We found a firm adhesion and stitches around right lower ureter over the uterus, which lead to an additional hysterectomy. After surgery, urinary incontinence had improved. Following two years after surgery, we observed no urinary incontinence or renal dysfunction.
