Abstract
Abstract
American Cancer Society acknowledges that most skin cancers result from exposure to ultraviolet (UV) rays in sunlight. UVB radiation induces mutant cells as well as immune suppression. Tumors only occur when mutant cells are in an immune suppressive environment. The mechanisms for UVB induced immune suppression are yet to be fully elucidated. The goal of this work is to explore new mechanisms for UVB induced immune suppression and skin carcinogenesis by using advanced technology. Analysis of UVB exposed mouse (Nanostring) and human (RNAseq) skin shows that triggering receptor expressed on myeloid cells (TREM)-1 signal pathway is the top canonic pathway increased by UVB. TREM-1 has roles in inflammatory diseases and cancers. However, its role in UVB induced immune suppression and skin cancers is not understood. We have found by using multi-color flow cytometry that UVB induces TREM-1 expression in a subset of conventional dendritic cell type 2 (cDC2) in the draining lymph nodes (LN). TREM-1+ cDC2 cells are barely detected in normal LN and express a high level of the co-inhibitory molecule PD-L1. In functional assays, treatment of mice with a specific TREM-1 blocking peptide LP-17 significantly diminishes UVB-induced suppression of contact hypersensitivity responses that are mediated by T cells. Further, mice treated with this peptide show decreased incidence of photocarcinogenesis and reduced number of tumors. In summary, our findings demonstrate that UVB induces the development of a novel TREM-1+ cDC2 cell subset and that TREM-1 has an important role in UVB induced immune suppression and skin carcinogenesis. Importantly, our study implies new strategies for targeting TREM-1 in the prevention and treatment of UVB induced skin cancers.

Abstract
Abstract
An inclined flow channel instrument that can be developed to be a structurally simple and easy-to-use rheometer was applied to control the thickness, specifically the viscosity and elasticity, of liquids thickened to support swallowing in nursing-care practice. Aqueous solutions containing salt or acid, which might be used as ingredients in drinks, were thickened with a commercial thickener. The thickener efficacy decreased because of the salt or acid in liquid phase. Analysis of the flows in the instrument by experimentation yielded a dimensionless relation representing changes of the Deborah number in the flow process, as indicated by the relative flow length, considering the shear rate in oral processing. One unique methodology to evaluate the viscoelasticities of thickened liquids during the swallowing process was presented utilizing the measurements such as elapsed time and velocity in the instrument.

Abstract
BACKGROUND Akkermansia muciniphila (AM) is a gram-negative, mucin-degrading bacteria inhabiting the gastrointestinal tract associated with host phenotypes and disease states. OBJECTIVE Explore characteristics of overweight and obese female early-stage (0 to II) breast cancer patients with low AM relative abundance (LAM) vs high (HAM) enrolled in a presurgical weight-loss trial. DESIGN Secondary analysis of pooled participants in a randomized controlled trial (NCT02224807). PARTICIPANTS/SETTING During the period from 2014 to 2017, 32 female patients with breast cancer were randomized to weight-loss or attention-control arms from time of diagnosis-to-lumpectomy (mean=30±9 days). INTERVENTION All were instructed to correct nutrient deficiencies via food sources and on upper-body exercises. The weight-loss group received additional guidance to promote 0.5 to 1 kg/wk weight-loss via energy restriction and aerobic exercise. MAIN OUTCOME MEASURES At baseline and follow-up, sera, fecal samples, two-24 hour dietary recalls and dual x-ray absorptiometry were obtained. Bacterial DNA was isolated from feces and polymerase chain reaction (16S) amplified. Inflammatory cytokines were measured in sera. STATISTICAL ANALYSES PERFORMED Differences between LAM and HAM participants were analyzed using t tests and nonparametric tests. Spearman correlations explored relationships between continuous variables. RESULTS Participants were aged 61±9 years with body mass index 34.8±6. Mean AM relative abundance was 0.02% (0.007% to 0.06%) and 1.59% (0.59% to 13.57%) for LAM and HAM participants, respectively. At baseline, women with HAM vs LAM had lower fat mass (38.9±11.2 kg vs 46.4±9.0 kg; P=0.044). Alpha diversity (ie, species richness) was higher in women with HAM (360.8±84.8 vs 282.4±69.6; P=0.008) at baseline, but attenuated after weight-loss (P=0.058). At baseline, interleukin-6 level was associated with species richness (ρ=-0.471, P=0.008) and fat mass (ρ=0.529, P=0.002), but not AM. Change in total dietary fiber was positively associated with AM in LAM (ρ=0.626, P=0.002), but not HAM (ρ=0.436, P=0.180) participants. CONCLUSIONS Among women with early-stage breast cancer, body composition is associated with AM, microbiota diversity, and interleukin-6 level. AM may mediate the effects of dietary fiber in improving microbiota composition.

Abstract
BACKGROUND Holistic approaches are sought to improve lifestyle behaviors and health of cancer survivors long term. OBJECTIVE Our aim was to explore whether a home-based vegetable gardening intervention is feasible and whether it improves diet and other health-related outcomes among older cancer survivors. DESIGN We conducted a feasibility trial in which cancer survivors were randomized to receive a year-long gardening intervention immediately or to a wait-list control arm. Home visits at baseline and 1 year assessed physical performance, anthropometric indices, behavioral and psychosocial outcomes, and biomarkers. PARTICIPANTS/SETTING Participants included 46 older (aged 60+ years) survivors of locoregionally staged cancers across Alabama from 2014 to 2016. Forty-two completed 1-year follow-up. INTERVENTION Cooperative extension master gardeners delivered guidance to establish three seasonal vegetable gardens at survivors' homes. Plants, seeds, and gardening supplies were provided. OUTCOMES Primary outcomes were feasibility targets of 80% accrual and retention, and an absence of serious adverse events; other outcomes were secondary and explored potential benefits. STATISTICAL ANALYSES Baseline to follow-up changes were assessed within and between arms using paired t, McNemar's, and χ2 tests. RESULTS This trial proved to be safe and demonstrated 91.3% retention; 70% of intervention participants rated their experience as "excellent," and 85% would "do it again." Data suggest significantly increased reassurance of worth (+0.49 vs -0.45) and attenuated increases in waist circumference (+2.30 cm vs +7.96 cm) in the gardening vs control arms (P=0.02). Vegetable and fruit consumption increased by approximately 1 serving/day within the gardening arm from baseline to follow-up (mean [standard error]=1.34 [1.2] to 2.25 [1.9] servings/day; P=0.02)] compared to controls (1.22 [1.1] to 1.12 [0.7]; P=0.77; between-arm P=0.06). CONCLUSIONS The home vegetable gardening intervention among older cancer survivors was feasible and suggested improvements in vegetable and fruit consumption and reassurance of worth; data also suggest attenuated increases in waist circumference. Continued study of vegetable gardening interventions is warranted to improve health, health behaviors, and well-being of older cancer survivors.

Abstract
PURPOSE Cancer survivors are at greater risk of comorbidities and functional decline due to physiological and psychological stress which can be measured by salivary cortisol. If saliva is used, multiple samples must be collected to accurately quantify long-term stress; however, fingernail (FN) and toenail (TN) clippings offer an opportunity to measure retrospective cortisol levels in a non-invasive manner. METHODS Three sets of FN and TN clippings were collected at 12-month intervals in conjunction with saliva samples from cancer survivors (n = 109) participating in two clinical trials. FN and TN samples were stored at room temperature (RT); a subset underwent additional processing and freezing before analysis. Cortisol levels were determined via enzyme immunoassay, and correlation coefficients were generated to determine overall correspondence of the individual measures. RESULTS Matched RT and frozen samples were highly correlated for TN (r = 0.950, p = 5.44 × 10-37) and FN (r = 0.784, p = 1.05 × 10-10). Correlations between RT FN and TN were statistically significant (r = 0.621, p = 3.61 × 10- 17), as were frozen FN and TN (r = 0.310, p = 0.0283). RT, but not frozen TN and FN correlated with salivary cortisol (r = 0.580, p = 1.65 × 10- 16 and r = 0.287, p = 0.00042 for TN and FN, respectively). CONCLUSIONS FN and TN cortisol levels correlate with salivary cortisol in adult cancer survivors and may offer a less invasive and convenient means for measuring chronic cortisol levels.

Abstract
AbstractTo develop a structurally simple and easy-to-use viscometer for liquid foods, flow measurements and analyses were done in a flow channel instrument. Newtonian and non-Newtonian test liquids respectively employed in the experiments show viscosity and viscoelasticity. Changes of the modified friction coefficient during the flow processes characterized viscous flow in the instrument. The elasticity was found to be dominant in the early process, reducing the flow as a function of the relative magnitude of liquid viscoelasticity.

Abstract
In animal models, IL-12 and IL-23 participate in the development of malignant neoplasms of keratinocytes. However, the role of these cytokines in pigmented lesion development and their progression to melanoma has received little attention. IL-12p35, IL-23p19, and IL-12/IL-23p40 knockout mice on a C3H/HeN background, subjected to a melanomagenesis protocol, demonstrated profound differences in susceptibility to nevus initiation, transformation, tumorigenicity, and metastatic potential. IL-23 was found to be essential for melanocyte homeostasis, whereas IL-12 supported nevus development. A direct action of IL-23 on primary melanocytes, shown to be IL-23R+, demonstrated that DNA repair of damaged melanocytes requires IL-23. Furthermore, IL-23 modulated the cutaneous microenvironment by limiting regulatory T cells and IFN-γ and inhibiting IL-10 production. Neutralizing Ab to IFN-γ, but not IL-17, inhibited nevus development (p < 0.01).

Abstract
BACKGROUND Diet and obesity influence prostate cancer risk and progression-effects that may be mediated through the gut microbiome. OBJECTIVE Our aim was to explore relationships among diet, gut microbes, and Gleason sum in overweight and obese prostate cancer patients enrolled in a presurgical weight-loss trial. DESIGN Randomized controlled trial (NCT01886677) secondary analysis. PARTICIPANTS/SETTING In 2013-2014, 40 prostate cancer patients in the southeastern United States were randomized and allocated equally to weight-loss and wait-list control arms while they awaited prostatectomy; stool samples were collected on a subset of 22 patients. INTERVENTION Registered dietitian nutritionists and exercise physiologists provided semi-weekly in-person and telephone-based guidance on calorie-restricted diets and exercise to promote an approximate weight loss of 0.91 kg/wk. MAIN OUTCOME MEASURES Baseline and follow-up 24-hour dietary recalls were conducted and analyzed (using the Automated Self-Administered 24-hour dietary recall system; National Cancer Institute, Bethesda, MD) for macronutrients, micronutrients, and food groups. Microbiome analysis targeting the V4 region of the 16S ribosomal RNA gene was performed on fecal samples. Biopsy Gleason sum data were accessed from diagnostic pathology reports. STATISTICAL ANALYSES PERFORMED Associations between dietary factors and operational taxonomic units were determined by β-diversity analysis. Wilcoxon signed rank, and Mann-Whitney U testing assessed within- and between-arm differences. Associations between Gleason sum and operational taxonomic units, and diet and operational taxonomic units, were analyzed using Spearman correlations. RESULTS At baseline, Proteobacteria (median 0.06, interquartile range 0.01 to 0.16) were abundant, with four orders positively associated with Gleason sum. Gleason sum was associated with Clostridium (ρ=.579; P=0.005) and Blautia (ρ=-0.425, P=0.049). Increased red meat consumption from baseline was associated with Prevotella (ρ=-.497; P=0.018) and Blautia (ρ=.422; P=0.039). Men who increased poultry intake had decreased Clostridiales abundance (P=0.009). CONCLUSIONS This hypothesis-generating study provides a starting point for investigating the relationships between the fecal microbiome, diet, and prostate cancer. Adequately powered studies are required to further explore and validate these findings.

Abstract
INTRODUCTION Obesity is a known risk factor for postmenopausal breast cancer and is associated with poorer prognosis for premenopausal and postmenopausal patients; however, the aetiological mechanisms are unknown. Preclinical studies support weight loss via caloric restriction and increased physical activity as a possible cancer control strategy, though few clinical studies have been conducted. We undertook a feasibility trial among women recently diagnosed with stage 0-II breast cancer hypothesising that presurgical weight loss would be feasible, safe and result in favourable changes in tumour markers and circulating biomarkers. METHODS AND ANALYSIS A two-arm randomised controlled trial among 40 overweight or obese women, newly diagnosed with stage 0-II breast cancer and scheduled for surgery was planned. The attention control arm received upper body progressive resistance training and diet counselling to correct deficiencies in nutrient intake; the experimental arm received the same plus counselling on caloric restriction and aerobic exercise to achieve a weight loss of 0.68-0.919 kg/week. In addition to achieving feasibility benchmarks (accruing and retaining at least 80% of participants, and observing no serious adverse effects attributable to the intervention), we will explore the potential impact of an acute state of negative energy balance on tumour proliferation rates (Ki-67), as well as other tumour markers, serum biomarkers, gene expression, microbiome profiles and other clinical outcomes (eg, quality of life). Outcomes for the 2 study arms are compared using mixed models repeated-measures analyses. ETHICS AND DISSEMINATION Ethics approval was received from the University of Alabama at Birmingham Institutional Review Board (Protocol number F130325009). Study findings will be disseminated through peer-reviewed publications. Given that this is one of the first studies to investigate the impact of negative energy balance directly on tumour biology in humans, larger trials will be pursued if results are favourable.

Abstract
Background Obesity is associated with tumor aggressiveness and disease-specific mortality for more than 15 defined malignancies, including prostate cancer. Preclinical studies suggest that weight loss from caloric restriction and increased physical activity may suppress hormonal, energy-sensing, and inflammatory factors that drive neoplastic progression; however, exact mechanisms are yet to be determined, and experiments in humans are limited. Methods We conducted a randomized controlled trial among 40 overweight or obese, newly-diagnosed prostate cancer patients who elected prostatectomy to explore feasibility of a presurgical weight loss intervention that promoted a weight loss of roughly one kg. week−1 via caloric restriction and physical activity, as well as to assess effects on tumor biology and circulating biomarkers. Measures of feasibility (accrual, retention, adherence, and safety) were primary endpoints. Exploratory aims were directed at the intervention’s effect on tumor proliferation (Ki-67) and other tumor markers (activated caspase-3, insulin and androgen receptors, VEGF, TNFβ, NFκB, and 4E-BP1), circulating biomarkers (PSA, insulin, glucose, VEGF, TNFβ, leptin, SHBG, and testosterone), lymphocytic gene expression of corresponding factors and cellular bioenergetics in neutrophils, and effects on the gut microbiome. Consenting patients were randomized in a 1:1 ratio to either: 1) weight loss via a healthful, guidelines-based diet and exercise regimen; or 2) a wait-list control. While biological testing is currently ongoing, this paper details our methods and feasibility outcomes. Results The accrual target was met after screening 101 cases (enrollment rate: 39.6 %). Other outcomes included a retention rate of 85 %, excellent adherence (95 %), and no serious reported adverse events. No significant differences by age, race, or weight status were noted between enrollees vs. non-enrollees. The most common reasons for non-participation were “too busy” (30 %), medical exclusions (21 %), and “distance” (16 %). Conclusions Presurgical trials offer a means to study the impact of diet and exercise interventions directly on tumor tissue, and other host factors that are feasible and safe, though modifications are needed to conduct trials within an abbreviated period of time and via distance medicine-based approaches. Pre-surgical trials are critical to elucidate the impact of lifestyle interventions on specific mechanisms that mediate carcinogenesis and which can be used subsequently as therapeutic targets.

Abstract
Acquired melanocytic nevi are commonly found in sun exposed and unexposed human skin, but the potential for their transformation into invasive melanoma is not clear. Therefore, a mouse model of nevus initiation and progression was developed in C3H/HeN mice using a modified chemical carcinogenesis protocol. Nevi develop due to DNA damage initiated by dimethylbenz(a) anthracene (DMBA) followed by chronic promotion with 12‐O‐tetradecanoyl‐phorbol‐13‐acetate (TPA). Dysplastic pigmented skin lesions appeared in 7–9 wk with 100% penetrance. Nests of melanocytic cells appeared in a subset of skin draining lymph nodes (dLN) by 25 wk, but not in age matched controls. Immunohistochemistry, real‐time PCR, and flow cytometric analyses confirmed their melanocytic origin. Transformed cells were present in a subset of nevi and dLNs, which exhibited anchorage‐independent growth, tumor development, and metastasis in nude mice. Approximately 50% of the cell lines contained H‐Ras mutations and lost tumor suppressor p16Ink4a expression. While most studies of melanoma focus on tumor progression in transgenic mouse models where the mutations are present from birth, our model permits investigation of acquired mutations at the earliest stages of nevus initiation and promotion of nevus cell transformation. This robust nevus/melanoma model may prove useful for identifying genetic loci associated with nevus formation, novel oncogenic pathways, tumor targets for immune‐prevention, screening therapeutics, and elucidating mechanisms of immune surveillance and immune evasion. © 2015 The Authors.

Abstract
Prevention of tumors induced by environmental carcinogens has not been achieved. Skin tumors produced by polyaromatic hydrocarbons, such as 7,12-dimethylbenz(a)anthracene (DMBA), often harbor an H-ras point mutation, suggesting that it is a poor target for early immunosurveillance. The application of pyrosequencing and allele-specific PCR techniques established that mutations in the genome and expression of the Mut H-ras gene could be detected as early as 1 d after DMBA application. Further, DMBA sensitization raised Mut H-ras epitope-specific CTLs capable of eliminating Mut H-ras(+) preneoplastic skin cells, demonstrating that immunosurveillance is normally induced but may be ineffective owing to insufficient effector pool size and/or immunosuppression. To test whether selective pre-expansion of CD8 T cells with specificity for the single Mut H-ras epitope was sufficient for tumor prevention, MHC class I epitope-focused lentivector-infected dendritic cell- and DNA-based vaccines were designed to bias toward CTL rather than regulatory T cell induction. Mut H-ras, but not wild-type H-ras, epitope-focused vaccination generated specific CTLs and inhibited DMBA-induced tumor initiation, growth, and progression in preventative and therapeutic settings. Transferred Mut H-ras-specific effectors induced rapid tumor regression, overcoming established tumor suppression in tumor-bearing mice. These studies support further evaluation of oncogenic mutations for their potential to act as early tumor-specific, immunogenic epitopes in expanding relevant immunosurveillance effectors to block tumor formation, rather than treating established tumors.

Abstract
Abstract
The function of Langerhans cells (LCs) in the skin immune system is unclear, and a matter of intense debate. In different mouse models LCs have been shown to induce antitumor immunity or promote skin squamous cell carcinoma (SCC). Their role in the control or promotion of melanoma is not known. We assessed LC's role in the development of DMBA-TPA induced pigmented benign and transformed lesions in a novel mouse model. Transgenic HuLang-DTA+/- C57Bl/6 mice, which selectively ablate epidermal LCs, were crossed with C3H/HeN mice to generate F1 LC knockout (KO) and WT littermate controls. LC-KO mice developed 40% more and 2-fold larger melanocytic lesions than WT. Cell suspensions from LC-KO pigmented skin lesions contained increased CD4+ Foxp3+ regulatory T cells and CD11b-/loGr-1hi cells, consistent with an immunosuppressive microenvironment. CD11c+CD11b+Ly6C+ APCs or MHCII+ cell numbers were fewer in lesions from LC-KO as compared to WT mice. Nests of melanocytic cells were observed at a higher frequency in draining lymph nodes (dLNs) from LC-KO as compared to WT; DLN cells contained increased numbers of TRP2+ cells and routinely gave rise to proliferative melanocytic cell lines. Real-time PCR analysis of epidermal cDNA from TPA treated LC-KO, as compared to WT, demonstrated a profound loss of IL-10, IL-12p35 and IL-12p40, indicating LCs as the major source. Further, IL-23 steady state levels in the epidermis of LC-KO are increased greater than 3-fold over WT, indicating that LCs normally suppress keratinocyte production of IL-23. Thus, in contrast to SCC, LCs inhibit development of benign and metastatic pigmented tumors. This novel murine model will be useful in elucidating transformation mechanisms and identifying novel therapeutic targets that may prevent metastatic melanoma.

Abstract
The spontaneous crescentic glomerulonephritis-forming/Kinjoh (SCG/Kj) mouse, a model of human crescentic glomerulonephritis (CrGN) and systemic vasculitis, is characterized by the production of myeloperoxidase-specific anti-neutrophil cytoplasmic autoantibody (MPO-ANCA) and marked leucocytosis. This study was performed to identify the specific populations of leucocytes associated with CrGN and susceptibility loci for pathogenic leucocytosis. Four hundred and twenty female (C57BL/6 × SCG/Kj) F2 intercross mice were subjected to serial flow cytometry examination of the peripheral blood (PB). Kidney granulocytes and monocytes were examined histopathologically. Linkage analyses were performed with 109 polymorphic microsatellite markers. Correlation studies revealed that increase of the granulocytes, F4/80(+) cells, CD3(+) CD4(-) CD8(-) T cells and dendritic cells (DCs) in peripheral blood (PB) were associated significantly with glomerulonephritis, crescent formation and vasculitis. In kidney sections, F4/80(low) cells were observed in crescent, while F4/80(high) cells were around the Bowman's capsules and in the interstitium. Numbers of F4/80(+) cells in crescents correlated significantly with F4/80(+) cell numbers in PB, but not with numbers of F4/80(+) cells in the interstitium. Genome-wide quantitative trait locus (QTL) mapping revealed three SCG/Kj-derived non-Fas QTLs for leucocytosis, two on chromosome 1 and one on chromosome 17. QTLs on chromosome 1 affected DCs, granulocytes and F4/80(+) cells, but QTL on chromosome 17 affected DCs and granulocytes. We found CrGN-associated leucocytes and susceptibility QTLs with their positional candidate genes. F4/80(+) cells in crescents are considered as recruited inflammatory macrophages. The results provide information for leucocytes to be targeted and genetic elements in CrGN and vasculitis.

Abstract
BACKGROUND Osteopontin (OPN) is a matricellular glycoprotein that is markedly expressed in cutaneous squamous cell carcinomas (cSCCs) and in actinic keratoses implicating its role in photocarcinogenesis. OBJECTIVE To determine whether OPN facilitates the development of cSCC and its function. METHODS cSCCs development was compared between wild-type (WT) and OPN-null mice subjected to UVB irradiation for 43 weeks. UVB-induced OPN expression was determined by Western blot, immunoprecipitation, ELISA, and semi-quantitative RT-PCR. Epidermal layer and TUNEL analyses assessed if OPN mediates UVB-induced epidermal hyperplasia or suppresses UVB-induced apoptosis of basal keratinocytes, respectively. In vitro experiments determined whether OPN enhances cell survival of UVB-induced apoptosis and its potential mechanisms. Immunohistochemical analyses of epidermis assessed the expression of CD44 and focal adhesion kinase (FAK), molecules that mediate OPN survival function. RESULTS Compared to female WT mice, OPN-null mice did not develop cSCCs. UVB irradiation stimulated OPN protein expression in the dorsal skin by 11h and remains high at 24-48h. OPN did not mediate UVB-induced epidermal hyperplasia; instead, it protected basal keratinocytes from undergoing apoptosis upon UVB exposure. Likewise, the addition of OPN suppressed UVB-induced OPN-null cSCC cell apoptosis, the activation of caspase-9 activity, and increased phosphorylation of FAK at Y397. Furthermore, the expression of CD44 and FAK in WT mice epidermis was greater than that of OPN-null mice prior to and during early acute UVB exposure. CONCLUSION These data support the hypothesis that chronic UVB-induced OPN expression protects the survival of initiated basal keratinocytes and, consequently, facilitates cSCC develop.

Abstract
BACKGROUND AND AIMS Serum malondialdehyde-modified low-density lipoprotein (MDA-LDL) and MDA-LDL/LDL-cholesterol (LDL-c) ratio are risk factors for arteriosclerosis and cardiovascular disease (CVD). However, no information is available on these parameters or their associations with coronary artery calcification (CAC) in haemodialysis (HD) patients. METHODS AND RESULTS Fifty-seven HD patients and 26 control subjects were included in this cross-sectional study. Serum MDA-LDL concentrations and MDA-LDL/LDL-c ratios were examined. HD patients had significantly higher MDA-LDL/LDL-c ratios than the controls (105.1 ± 27.5 vs. 81.4 ± 18.9 mU/mg, P < 0.001); however, there was no significant difference in serum MDA-LDL levels between the 2 groups. CAC scores were examined only in HD patients and their possible associations with the clinical/laboratory data were analysed. Analysis of HD patients showed that MDA-LDL/LDL-c ratio has an association with presence of CVD, CAC score, HD duration, MDA-LDL, or haemoglobin A1C. In addition, the CAC score was positively correlated with serum MDA-LDL level (P = 0.048) and MDA-LDL/LDL-c ratio (P = 0.006). Furthermore, multivariate logistic regression analysis showed that MDA-LDL/LDL-c ratio (β = 0.04, P = 0.003) and HD duration (β = 0.16, P = 0.007) were independently associated with CAC score. CONCLUSION The MDA-LDL/LDL-c ratio of HD patients was significantly higher than that of non-HD subjects and was independently associated with the CAC score. Therefore, this ratio could be an important risk factor for CAC in HD patients.

Abstract
PURPOSE To evaluate a dosimetric accuracy of AcurosXB dose calculation algorithm for 4 MV photon beam. METHODS Four MV beam (Clinac-6EX) and AAA and AcurosXB algorithms (pre-release version 11.0.03.) were used in this study. The differences of the calculation with AAA (EAAA) and AcurosXB (EAXB) to the measurement were evaluated in the depth doses to 25 cm depth and dose profiles within the water and slab phantoms (water, lung and bone equivalent). In addition, the clinical cases, including three whole breast plans and three head and neck IMRT plans, were evaluated. First the AAA plans were calculated, then AcurosXB plans were recalculated with dose-to-medium with identical beam setup and monitor units as in the AAA plan. RESULTS In the water phantom study, the EAAA and EAXB were up to 2.2% and 1.5% in the depth doses for the open field (field size = 4 - 40cm square), respectively. Under the heterogeneity conditions, the EAAA and EAXB were less than 4.4% and 2.2% in lung region, and less than 12.5% and 6.3% in bone region, respectively. In the re-buildup region after passing through the lung phantom, the AAA overestimated the doses about 10%; however AcurosXB had good agreement with measurement within 3%. Dose profiles with AcurosXB were better agreement with measurement than AAA. In the clinical cases, the dose of the skin surface region with AcurosXB were higher than AAA by at least 10%, and the dose differences over 5% appeared in heterogeneous region. However, DVH shapes of each organ were similar between AAA and AcurosXB within 2%. CONCLUSIONS In phantom study, AcurosXB had better agreement to measurement than AAA, especially in heterogeneous region and re-buildup region. In the clinical cases, there were large differences between AcurosXB and AAA in the surface region. Evaluation Agreement of non-clinical versions of Acuros XB with Varian Medical Systems.

Abstract
The gene therapy field is currently limited by the lack of vehicles that permit efficient gene delivery to specific cell or tissue subsets. Native viral vector tropisms offer a powerful platform for transgene delivery but remain nonspecific, requiring elevated viral doses to achieve efficacy. In order to improve upon these strategies, our group has focused on genetically engineering targeting domains into viral capsid proteins, particularly those based on adenovirus serotype 5 (Ad5). Our primary strategy is based on deletion of the fiber knob domain, to eliminate broad tissue specificity through the human coxsackie-and-adenovirus receptor (hCAR), with seamless incorporation of ligands to re-direct Ad tropism to cell types that express the cognate receptors. Previously, our group and others have demonstrated successful implementation of this strategy in order to specifically target Ad to a number of surface molecules expressed on immortalized cell lines. Here, we utilized phage biopanning to identify a myeloid cell-binding peptide (MBP), with the sequence WTLDRGY, and demonstrated that MBP can be successfully incorporated into a knob-deleted Ad5. The resulting virus, Ad.MBP, results in specific binding to primary myeloid cell types, as well as significantly higher transduction of these target populations ex vivo, compared to unmodified Ad5. These data are the first step in demonstrating Ad targeting to cell types associated with inflammatory disease.

Abstract
Abstract
Inflammation is a pathological component of many debilitating lung diseases. Thus, therapeutics that suppress the inflammatory response should also minimize inflammation-induced airway destruction. In this regard, Adenovirus type 5 (Ad5) vectors have a long history as therapeutic agents, due to their in vivo stability and amenability to genetic manipulation. Since circulating leukocytes infiltrate and mediate damage to the sites of pathology, we proposed to modulate Ad5 tropism to the dense leukocyte pool in the lung microvasculature for localized therapeutic intervention of inflammation. However, leukocytes do not express the coxsackie and adenovirus receptor (CAR) and are thus resistant to Ad5 infection. Therefore, we utilized phage display to identify a myeloid-binding peptide (MBP) and then genetically incorporated this sequence into an Ad5 fiber lacking the native CAR-binding domain (knob). Non-replicative Ad reporter vectors containing these MBP-fibers (Ad.MBP) maintained myeloid-binding specificity, and upon intravenous delivery the altered tropism enhanced lung gene transfer by five orders of magnitude over that obtained with unmodified Ad5. Disparity between cell types bound and those transduced suggest Ad.MBP is first sequestered by circulating leukocytes and subsequently “handed-off” to transduce pulmonary endothelium. These studies highlight the importance of pulmonary leukocytes as a target for therapeutic delivery in inflammatory lung disease.

Abstract
Adenoviral (Ad) vectors have been used for a variety of vaccine applications including cancer and infectious diseases. Traditionally, Ad-based vaccines are designed to express antigens through transgene expression of a given antigen. However, in some cases these conventional Ad-based vaccines have had sub-optimal clinical results. These sub-optimal results are attributed in part to pre-existing Ad serotype 5 (Ad5) immunity. In order to circumvent the need for antigen expression via transgene incorporation, the “antigen capsid-incorporation” strategy has been developed and used for Ad-based vaccine development in the context of a few diseases. This strategy embodies the incorporation of antigenic peptides within the capsid structure of viral vectors. The major capsid protein hexon has been utilized for these capsid incorporation strategies due to hexon's natural role in the generation of anti-Ad immune response and its numerical representation within the Ad virion. Using this strategy, we have developed the means to incorporate heterologous peptide epitopes specifically within the major surface-exposed domains of the Ad capsid protein hexon. Our study herein focuses on generation of multivalent vaccine vectors presenting HIV antigens within the Ad capsid protein hexon, as well as expressing an HIV antigen as a transgene. These novel vectors utilize HVR2 as an incorporation site for a twenty-four amino acid region of the HIV membrane proximal ectodomain region (MPER), derived from HIV glycoprotein gp41 (gp41). Our study herein illustrates that our multivalent anti-HIV vectors elicit a cellular anti-HIV response. Furthermore, vaccinations with these vectors, which present HIV antigens at HVR2, elicit a HIV epitope-specific humoral immune response.

Abstract
RATIONALE Urokinase-type plasminogen activator (uPA) receptor (uPAR) is required for the recruitment of neutrophils in response to infection. uPA induces its own expression in lung epithelial cells, which involves its interaction with cell surface uPAR. Regulation of uPAR expression is therefore crucial for uPA-mediated signaling in infectious acute lung injury (ALI). OBJECTIVES To determine the role of uPA in uPAR expression during ALI caused by sepsis. METHODS We used Western blot, Northern blot, Northwestern assay, and immunohistochemistry. Phosphate-buffered saline- and lipopolysaccharide (LPS)-treated wild-type and uPA(-/-) mice were used. MEASUREMENTS AND MAIN RESULTS Biological activities of uPA, including proteolysis, cell adhesion, migration, proliferation, and differentiation, are dependent on its association with uPAR. Bacterial endotoxin (LPS) is a major cause of pulmonary dysfunction and infection-associated mortality. The present study shows that LPS induces uPAR expression both in vitro and in vivo, and that the mechanism involves post-transcriptional stabilization of uPAR mRNA by reciprocal interaction of phosphoglycerate kinase (PGK) and heterogeneous nuclear ribonucleoprotein C (hnRNPC) with uPAR mRNA coding region and 3' untranslated region determinants, respectively. The process involves tyrosine phosphorylation of PGK and hnRNPC. uPA(-/-) mice failed to induce uPAR expression after LPS treatment. In these mice, LPS treatment failed to alter the binding of PGK and hnRNPC protein with uPAR mRNA due to lack of tyrosine phosphorylation. CONCLUSIONS Our study shows that induction of LPS-mediated uPAR expression is mediated through tyrosine phosphorylation of PGK and hnRNPC. This involves expression of uPA as an obligate intermediary.

Abstract
RATIONALE Although reactive oxygen species (ROS) are generally considered to be proinflammatory and to contribute to cellular and organ dysfunction when present in excessive amounts, there is evidence that specific ROS, particularly hydrogen peroxide (H(2)O(2)), may have antiinflammatory properties. OBJECTIVES To address the role that increases in intracellular H(2)O(2) may play in acute inflammatory processes, we examined the effects of catalase inhibition or the absence of catalase on LPS-induced inflammatory responses. METHODS Neutrophils from control or acatalasemic mice, or control neutrophils incubated with the catalase inhibitor aminotriazole, were treated with LPS, and levels of reactive oxygen species, proteasomal activity, NF-kappaB activation, and proinflammatory cytokine expression were measured. Acute lung injury (ALI) was produced by intratracheal injection of LPS into control, acatalasemic-, or aminotriazole-treated mice. MEASUREMENTS AND MAIN RESULTS Intracellular levels of H(2)O(2) were increased in acatalasemic neutrophils and in neutrophils exposed to aminotriazole. Compared with LPS-stimulated neutrophils from control mice, neutrophils from acatalasemic mice or neutrophils treated with aminotriazole demonstrated reduced 20S and 26S proteasomal activity, IkappaB-alpha degradation, NF-kappaB nuclear accumulation, and production of the proinflammatory cytokines TNF-alpha and macrophage inhibitory protein (MIP)-2. The severity of LPS-induced ALI was less in acatalasemic mice and in mice treated with aminotriazole as compared with that found in control mice. CONCLUSIONS These results indicate that H(2)O(2) has antiinflammatory effects on neutrophil activation and inflammatory processes, such as ALI, in which activated neutrophils play a major role.

Abstract
mTOR complex 1 (mTORC1) plays a central role in cell growth and cellular responses to metabolic stress. Although mTORC1 has been shown to be activated after Toll-like receptor (TLR)-4 engagement, there is little information concerning the role that mTORC1 may play in modulating neutrophil function and neutrophil-dependent inflammatory events, such as acute lung injury. To examine these issues, we determined the effects of rapamycin-induced inhibition of mTORC1 on TLR2- and TLR4-induced neutrophil activation. mTORC1 was dose- and time-dependently activated in murine bone marrow neutrophils cultured with the TLR4 ligand, LPS, or the TLR2 ligand, Pam(3) Cys-Ser-(Lys)(4) (PAM). Incubation of PAM- or LPS-stimulated neutrophils with rapamycin inhibited expression of TNF-alpha and IL-6, but not IkappaB-alpha degradation or nuclear translocation of NF-kappaB. Exposure of PAM or LPS-stimulated neutrophils to rapamycin inhibited phosphorylation of serine 276 in the NF-kappaB p65 subunit, a phosphorylation event required for optimal transcriptional activity of NF-kappaB. Rapamycin pretreatment inhibited PAM- or LPS-induced mTORC1 activation in the lungs. Administration of rapamycin also decreased the severity of lung injury after intratracheal LPS or PAM administration, as determined by diminished neutrophil accumulation in the lungs, reduced interstitial pulmonary edema, and diminished levels of TNF-alpha and IL-6 in bronchoalveolar lavage fluid. These results indicate that mTORC1 activation is essential in TLR2- and TLR4-induced neutrophil activation, as well as in the development and severity of acute lung injury.

Abstract
Phagocytosis of apoptotic cells, also called efferocytosis, is an essential feature of immune responses and critical to resolution of inflammation. Impaired efferocytosis is associated with an unfavorable outcome from inflammatory diseases, including acute lung injury and pulmonary manifestations of cystic fibrosis. High mobility group protein-1 (HMGB1), a nuclear nonhistone DNA-binding protein, has recently been found to be secreted by immune cells upon stimulation with LPS and cytokines. Plasma and tissue levels of HMGB1 are elevated for prolonged periods in chronic and acute inflammatory conditions, including sepsis, rheumatoid arthritis, acute lung injury, burns, and hemorrhage. In this study, we found that HMGB1 inhibits phagocytosis of apoptotic neutrophils by macrophages in vivo and in vitro. Phosphatidylserine (PS) is directly involved in the inhibition of phagocytosis by HMGB1, as blockade of HMGB1 by PS eliminates the effects of HMGB1 on efferocytosis. Confocal and fluorescence resonance energy transfer demonstrate that HMGB1 interacts with PS on the neutrophil surface. However, HMGB1 does not inhibit PS-independent phagocytosis of viable neutrophils. Bronchoalveolar lavage fluid from Scnn(+) mice, a murine model of cystic fibrosis lung disease which contains elevated concentrations of HMGB1, inhibits neutrophil efferocytosis. Anti-HMGB1 Abs reverse the inhibitory effect of Scnn(+) bronchoalveolar lavage on efferocytosis, showing that this effect is due to HMGB1. These findings demonstrate that HMGB1 can modulate phagocytosis of apoptotic neutrophils and suggest an alternative mechanism by which HMGB1 is involved in enhancing inflammatory responses.

Abstract
PURPOSE Recently, virotherapy has been proposed as a new therapeutic approach for ovarian cancer. Conditionally replicative adenoviruses (CRAd) may contain tumor-specific promoters that restrict virus replication to cancer cells. Mesothelin, a cell surface glycoprotein, is overexpressed in ovarian cancer but not in normal ovarian tissues. The purpose of this study was to explore the therapeutic utility of a mesothelin promoter-based CRAd in a murine model of ovarian cancer, using noninvasive in vivo imaging. EXPERIMENTAL DESIGN We constructed a mesothelin promoter-based CRAd with a chimeric Ad5/3 fiber (AdMSLNCRAd5/3) that contains an Ad5 tail, Ad5 shaft, and an Ad3 knob. Previously, a chimeric Ad5/3 fiber has shown improved infectivity in many ovarian cancer cells. Viral replication and oncolysis were assessed in a panel of ovarian cancer cell lines. To test the oncolytic efficacy of AdMSLNCRAd5/3 in a murine model, bioluminescence imaging of tumor luciferase activity and survival analysis were done. RESULTS AdMSLNCRAd5/3 achieved up to a 10,000-fold higher cell killing effect and up to 120-fold higher levels of viral replication in all human ovarian cancer cells, compared with wild-type Ad5. AdMSLNCRAd5/3 significantly inhibited tumor growth as confirmed by in vivo imaging (P < 0.05). Survival with AdMSLNCRAd5/3 was significantly enhanced when compared with no virus or with a wild-type Ad5-treated group (P < 0.05). CONCLUSIONS The robust replication, oncolysis, and in vivo therapeutic efficacy of AdMSLNCRAd5/3 showed that this CRAd is a promising candidate for treating ovarian cancer. Importantly, we have applied in vivo imaging that has allowed repeated and longitudinal measurements of tumor growth after CRAd treatment.

Abstract
Human ovarian cancer is a highly lethal malignant neoplasm in woman with no effective treatment if conventional chemotherapy fails. In this regard, conditionally replicative adenoviruses (CRAds) represent a promising new modality for the treatment of cancer. A key contribution to the development of CRAds was the introduction of tumor-selective viral replication to restrict amplification to the neoplastic cell population. Under ideal conditions following cellular infection, the viruses replicate selectively in the infected tumor cells, killing the cells by cytolysis, leaving normal cells unaffected. However, to date, there have been limitations to the clinical application of these CRAd agents i.e. poor viral infectivity, poor tumor specificity and high toxicity. Here, we report the in vitro and in vivo comparison of four CRAd agents developed for ovarian cancer application, specifically, Ad-Delta24.F5/3, CRAd-C.F5/3, CRAd-M.F5/3 and CRAd-S.F5/3. All CRAd agents contained fiber knob chimeras of adenovirus serotype 3, which enhanced the viral infectivity at the transductional level via a non-Coxsackie-Adenovirus Receptor alternative pathway. In addition, these CRAds embodied distinct mechanisms for the achievement of replication specificity. Tumor cell killing was assessed by using an oncolytic assay and a cell viability assay (MTS) in vitro, while tumor growth was examined in a xenograft model in vivo by using a bioluminescent imaging assay. In addition, the replication rates of the CRAd agents were determined in human liver slices. Both the Ad-Delta24.F5/3 and CRAd-S.F5/3 were demonstrated to have higher tumor killing effects in tumor cells and a lower viral replication rate in human liver. These agents are thus excellent candidates for clinical trials of CRAd agents against human ovarian cancer.

Abstract
AMP-activated protein kinase (AMPK) is activated by increases in the intracellular AMP-to-ATP ratio and plays a central role in cellular responses to metabolic stress. Although activation of AMPK has been shown to have anti-inflammatory effects, there is little information concerning the role that AMPK may play in modulating neutrophil function and neutrophil-dependent inflammatory events, such as acute lung injury. To examine these issues, we determined the effects of pharmacological activators of AMPK, 5-aminoimidazole-4-carboxamide-1-beta-d-ribofuranoside (AICAR) and barberine, on Toll-like receptor 4 (TLR4)-induced neutrophil activation. AICAR and barberine dose-dependently activated AMPK in murine bone marrow neutrophils. Exposure of LPS-stimulated neutrophils to AICAR or barberine inhibited release of TNF-alpha and IL-6, as well as degradation of IkappaBalpha and nuclear translocation of NF-kappaB, compared with findings in neutrophil cultures that contained LPS without AICAR or barberine. Administration of AICAR to mice resulted in activation of AMPK in the lungs and was associated with decreased severity of LPS-induced lung injury, as determined by diminished neutrophil accumulation in the lungs, reduced interstitial pulmonary edema, and diminished levels of TNF-alpha and IL-6 in bronchoalveolar lavage fluid. These results suggest that AMPK activation reduces TLR4-induced neutrophil activation and diminishes the severity of neutrophil-driven proinflammatory processes, including acute lung injury.

Abstract
RATIONALE Mitochondria have important roles in intracellular energy generation, modulation of apoptosis, and redox-dependent intracellular signaling. Although reactive oxygen species (ROS) participate in the regulation of intracellular signaling pathways, including activation of nuclear factor (NF)-kappaB, there is only limited information concerning the role of mitochondrially derived ROS in modulating cellular activation and tissue injury associated with acute inflammatory processes. OBJECTIVES To examine involvement of the mitochondrial electron transport chain complex I on LPS-mediated NF-kappaB activation in neutrophils and neutrophil-dependent acute lung injury. METHODS Neutrophils incubated with rotenone or metformin were treated with bacterial lipopolysaccharide (LPS) to determine the effects of mitochondrial complex I inhibition on intracellular concentrations of reactive oxygen species, NF-kappaB activation, and proinflammatory cytokine expression. Acute lung injury was produced by intratracheal injection of LPS into control, metformin, or rotenone-treated mice. MEASUREMENTS AND MAIN RESULTS Inhibition of complex I with either rotenone or the antihyperglycemic agent metformin was associated with increased intracellular levels of both superoxide and hydrogen peroxide, as well as inhibition of LPS-induced I kappaB-alpha degradation, NF-kappaB nuclear accumulation, and proinflammatory cytokine production. Treatment of LPS-exposed mice with rotenone or metformin resulted in inhibition of complex I in the lungs, as well as diminished severity of lung injury. CONCLUSIONS These results demonstrate that mitochondrial complex I plays an important role in modulating Toll-like receptor 4-mediated neutrophil activation and suggest that metformin, as well as other agents that inhibit mitochondrial complex I, may be useful in the prevention or treatment of acute inflammatory processes in which activated neutrophils play a major role, such as acute lung injury.

Abstract
Reactive oxygen species (ROS) contribute to neutrophil activation and the development of acute inflammatory processes in which neutrophils play a central role. However, there is only limited information concerning the mechanisms through which extracellular ROS, and particularly cell membrane-impermeable species, such as superoxide, enhance the proinflammatory properties of neutrophils. To address this issue, neutrophils were exposed to superoxide generating combinations of xanthine oxidase and hypoxanthine or lumazine. Extracellular superoxide generation induced nuclear translocation of nuclear factor-κB (NF-κB) and increased neutrophil production of the NF-κB-dependent cytokines tumor necrosis factor-α (TNF-α) and macrophage inhibitory protein-2 (MIP-2). In contrast, there were no changes in TNF-α or MIP-2 expression when neutrophils lacking Toll-like receptor-4 (TLR4) were exposed to extracellular superoxide. Immunoprecipitation, confocal microscopy, and fluorescence resonance energy transfer (FRET) studies demonstrated association between TLR4 and xanthine oxidase. Exposure of neutrophils to heparin attenuated binding of xanthine oxidase to the cell surface as well as interactions with TLR4. Heparin also decreased xanthine oxidase-induced nuclear translocation of NF-κB as well as production of proinflammatory cytokines. These results demonstrate that extracellular superoxide has proinflammatory effects on neutrophils, predominantly acting through an TLR4-dependent mechanism that enhances nuclear translocation of NF-κB and increases expression of NF-κB-dependent cytokines.

Abstract
IL-1R-associated kinase (IRAK)-1 is a critical mediator of TLR/IL-1R-induced activation of the transcription factor NF-kappaB. We previously described that a commonly occurring IRAK-1 variant haplotype, containing amino acid changes from serine to phenylalanine at position 196 and from leucine to serine at position 532, is associated with increased activation of NF-kappaB in LPS-stimulated neutrophils from patients with sepsis-induced acute lung injury and also higher mortality and more severe clinical outcomes in such patients. To investigate the underlying molecular mechanisms, we examined the ability of wild-type and variant IRAK-1 to modulate NF-kappaB activation. We found increased NF-kappaB transcriptional activity and expression of NF-kappaB-dependent proinflammatory cytokines in IL-1beta-stimulated IRAK-1-deficient cells transfected with variant IRAK-1 as compared with IRAK-1 wild type. IkappaB-alpha degradation was faster and p65 phosphorylation more prolonged after IL-1beta stimulation in cells expressing the IRAK-1 variant. However, IL-1-induced activation of MAPKs and nuclear translocation of NF-kappaB are comparable in both IRAK-1 variant- and IRAK-1 wild-type-expressing cells. Autophosphorylation of the IRAK-1 variant is greater than that found with wild-type IRAK-1. Additionally, variant IRAK-1 has greater interaction with TNFR-associated factor 6 than does wild-type IRAK-1. The enhanced activity of variant IRAK-1 appeared to be due to the alteration at aa 532, with only minimal effects being associated with change at aa 196. These results demonstrate that variant IRAK-1 is associated with alterations in multiple intracellular events that are likely to contribute to increased NF-kappaB activation and inflammatory responses in individuals with this IRAK-1 haplotype.

Abstract
PURPOSE Adenovirus serotype 5 (Ad5) has been used for gene therapy with limited success due to insufficient infectivity in cells with low expression of the primary receptor, the coxsackie and adenovirus receptor (CAR). Evidence that adenovirus serotype receptors other than CAR may be of use was presented in previous studies that showed that the Ad3 receptor is expressed at high levels in ovarian cancer cells. We hypothesized that combined use of unique chimeric fibers in the context of novel mosaic adenovirus vectors would enhance infectivity via non-CAR pathways in ovarian cancer cells. EXPERIMENTAL DESIGN We constructed and characterized Ad5 vectors that use Ad3 knob and reovirus fibers to generate a mosaic fiber virion. Serotype 3 Dearing reovirus uses a fiber-like sigma 1 protein to infect cells expressing sialic acid and junction adhesion molecule 1. We therefore constructed a mosaic fiber Ad5 vector, designated Ad5/3-sigma 1, encoding two fibers: a sigma 1 chimeric fiber and the chimeric Ad5/3 fiber composed of an Ad3 knob. RESULTS Functionally, Ad5/3-sigma 1 used sialic acid, junction adhesion molecule 1, and Ad3 receptor for cell transduction and achieved maximum infectivity enhancement in ovarian cancer cells with low CAR expression. Furthermore, Ad5/3-sigma 1 achieved infectivity enhancement in primary tissue slices of human ovarian tumor. CONCLUSIONS We have developed a new type of Ad5 vector with the novel tropism, possessing fibers from Ad3 and reovirus, which exhibits enhanced infectivity via CAR-independent pathway(s). In addition, the flexible genetic platform of vector allows different combination of fiber variants that can be incorporated within the same particle.

Abstract
Amyloid beta-protein ending at 42 (Abeta42) is the major peptide deposited in Alzheimer's disease (AD) brain. In immunocytochemical studies, formic acid treatment is used to dramatically enhance Abeta immunoreactivity. Recently, Abeta42 has been reported to accumulate in AD neurons. Since heating is known to enhance intracellular protein immunoreactivity, we used an autoclaving protocol to enhance intraneuronal Abeta42 immunoreactivity. Using this protocol, both anti-Abeta42 N-terminal and C-terminal antibodies, but not anti-Abeta40 C-terminal antibody, labeled AD neurons. Moreover, formic acid treatment counteracted such effects of autoclaving. Thus, intraneuronal Abeta42 accumulation may have been underestimated by conventional methods using formic acid only.

Abstract
10061 Background: Although a number of advances in ovarian cancer treatment have occurred in the last decade, most patients will experience a recurrence after standard therapies. Recently, virotherapy has been proposed as a new therapeutic approach for ovarian cancer. Conditionally replicative adenovirus (CRAd) contains tumor-specific promoters that restrict virus replication to cancer cells and has shown particular promise as oncolytic viral agents. However, the lack of a tumor-volume monitoring system hinders the evaluation of CRAd impact on cancer treatment. Therefore, methods for analyzing CRAd efficacy and tumor response are required. Mesothelin, a cell surface glycoprotein, is overexpressed in ovarian cancer but not in normal ovarian tissues. The purpose of this study was to explore the therapeutic utility of a mesothelin promoter-based CRAd in a murine model of ovarian cancer, using a non-invasive biological imaging system. Methods: We constructed a mesothelin promoter based CRAd which also contains a modified fiber (Ad5/3 fiber) previously shown to improve infectivity of many ovarian cancer cells (Ad5/3MSLN). Viral replication and oncolysis were assessed in a panel of ovarian cancer cell lines. To test the oncolytic efficacy of Ad5/3MSLN in murine model, firefly luciferase-expressing SK-OV-3-luc cells were injected intraperitoneally (i.p.), followed by an i.p. injection of viruses. Then, bioluminescence imaging of tumor luciferase activity was carried out. Results: Ad5/3MSLN achieved up to 10,000-fold higher cell killing effect and up to 120-fold higher levels of viral replication in all ovarian cancer cell lines tested, compared to wild type Ad5. In vivo tumor imaging confirmed that Ad5/3MSLN significantly inhibited tumor growth, while the untreated mice had rapid tumor growth (p<0.05). Survival with Ad5/3MSLN was significantly enhanced when compared with no virus, or wild type Ad5-treated group (p<0.05). Conclusions: The robust replication, oncolysis, and in vivo therapeutic efficacy of Ad5/3MSLN demonstrated that this CRAd is a promising candidate for treating ovarian cancer. Importantly, we have established an in vivo non-invasive imaging system, which has allowed repeated and longitudinal measurements of tumor growth after CRAd treatment.
