Abstract
Human Papillomavirus (HPV) is sexually transmitted and linked with vaginal, vulvar and cervix cancers in females, penile cancer in male, while anal and oropharyngeal cancer in both genders. Cervical cancer is ranked as third most identified cancer among females globally and is the fourth leading reason of cancer related mortality. The main aim of current study is to highlight the key role of miRNA in cervical cancer development, progression and their therapeutic responses. Current study entailed more than 50 PubMed cited articles related to miRNA role in cervical cancer. Studies have elucidated the role of miRNAs regulation in gene expression at post-transcriptional and translational level by targeting significant genes and therefore involved in cervical cancer. miRNAs control several cellular pathways involved in development of pre-malignant to metastatic stage and proliferation to malignancy. Current review elucidated and elaborated the key role of miRNA their application, treatment and therapeutic responses in cervical cancer.

Abstract
Lymphoepithelioma-like carcinoma of the bladder (LELC-B) is a rare subtype of urothelial carcinoma consisting of undifferentiated epithelial cells within a dense inflammatory cell infiltrate. We set out to molecularly characterize LELC-B through RNA expression profiling as well as immunohistochemistry (IHC) to understand its underlying biology. Sixteen cases of LELC-B were identified at Johns Hopkins University. RNA sequencing was performed on 14 cases. IHC staining for programmed cell death ligand 1 (PD-L1) and mismatch repair proteins MutL homolog 1 (MLH1), MutS homolog 2 (MSH2), MSH6, and PMS1 homolog, mismatch repair system component 2 (PMS2) was performed. Transcriptomic profiling of LELC-B showed that they are enriched in a basal-like phenotype, with 12 of 14 LELC-B cases correlating to the basal centroid of the bladder cancer analysis of subtypes by gene expression 47 (BASE47) predictive analysis of microarrays (PAM) classifier. Gene signature analysis confirmed the lymphocyte infiltration profile consistent with the histomorphology. LELC-B lacked features to explain the robust lymphocytic infiltrate, such as loss of mismatch repair protein expression or expression of Epstein-Barr virus transcripts. Nonetheless, PD-L1 IHC was positive in 93% of LELC cases. Our study demonstrates that LELC-B tumors are enriched in a basal-like molecular subtype and share a high level of immune infiltration and PD-L1 expression, similar to basal tumors. The basal-like phenotype is consistent with the known sensitivity of LELC-B to chemotherapy and suggests that immune checkpoint therapy should be explored in this rare disease.

Abstract
In 2014, the International Agency for Research on Cancer judged Merkel cell polyomavirus (MCPyV) to be a probable human carcinogen. BK polyomavirus (BKPyV, a distant cousin of MCPyV) was ruled a possible carcinogen. In this review, we argue that it has recently become reasonable to view both of these viruses as known human carcinogens. In particular, several complementary lines of evidence support a causal role for BKPyV in the development of bladder carcinomas affecting organ transplant patients. The expansion of inexpensive deep sequencing has opened new approaches to investigating the important question of whether BKPyV causes urinary tract cancers in the general population.

Abstract
PURPOSE The CANON [CAVATAK in NON-muscle-invasive bladder cancer (NMIBC)] study evaluated a novel ICAM-1-targeted immunotherapeutic-coxsackievirus A21 as a novel oncolytic agent against bladder cancer. PATIENTS AND METHODS Fifteen patients enrolled in this "window of opportunity" phase I study, exposing primary bladder cancers to CAVATAK prior to surgery. The first 9 patients received intravesical administration of monotherapy CAVATAK; in the second stage, 6 patients received CAVATAK with a subtherapeutic dose of mitomycin C, known to enhance expression of ICAM-1 on bladder cancer cells. The primary endpoint was to determine patient safety and maximum tolerated dose (MTD). Secondary endpoints were evidence of viral replication, induction of inflammatory cytokines, antitumor activity, and viral-induced changes in resected tissue. RESULTS Clinical activity of CAVATAK was demonstrated by induction of tumor inflammation and hemorrhage following either single or multiple administrations of CAVATAK in multiple patients, and a complete resolution of tumor in 1 patient. Whether used alone or in combination with mitomycin C, CAVATAK caused marked inflammatory changes within NMIBC tissue biopsies by upregulating IFN-inducible genes, including both immune checkpoint inhibitory genes (PD-L1 and LAG3) and Th1-associated chemokines, as well as the induction of the innate activator RIG-I, compared with bladder cancer tissue from untreated patients. No significant toxicities were reported in any patient, from either virus or combination therapy. CONCLUSIONS The acceptable safety profile of CAVATAK, proof of viral targeting, replication, and tumor cell death together with the virus-mediated increases in "immunological heat" within the tumor microenvironment all indicate that CAVATAK may be potentially considered as a novel therapeutic for NMIBC.

Abstract
OBJECTIVE To investigate the expression pattern of CD155 and evaluate the prognostic value of CD155 in muscle-invasive bladder cancer (MIBC). PATIENTS AND METHODS Immunohistochemical staining of CD155 and survival analysis were conducted on 228 nonmetastatic MIBC patients underwent radical cystectomy in cohorts from Fudan University Shanghai Cancer Center and Zhongshan Hospital. Association of CD155 gene expression with tumor stage and survival were analyzed in TCGA and GSE13507 dataset. RESULTS CD155 was significantly up-regulated in MIBC compared to matched normal urothelium and majorly stained on the membrane of tumor cells. In Fudan MIBC cohort, CD155 high expression was significantly correlated with shorter recurrence-free survival (HR = 2.13, P < 0.001) and overall survival (HR = 2.49, P < 0.001). CD155 expression, T stage, and lymph node status were independent factors for predicting survival in multivariate analysis. In TCGA dataset, CD155 high expression was independently associated with shorter overall survival (HR = 1.74, P = 0.001) beyond age, T stage, and lymph node status. Further, explorative analysis in Fudan MIBC cohort showed that adjuvant chemotherapy was associated with longer recurrence-free survival and overall survival in stage III and IV disease with CD155-high tumors. CONCLUSIONS These findings suggest that CD155 is a robust prognostic factor and may help predict the benefit of adjuvant chemotherapy in MIBC.

Abstract
Chaperone-assisted selective autophagy (CASA) is a newly-described selective tension-induced macroautophagy pathway mediated by Bag3 that is believed to be essential for mechanotransduction in skeletal muscle and to be an important regulator of the immune system. We investigated CASA machinery both in healthy and in fifteen papillomavirus-associated neoplastic bovine urothelium. The components of CASA complex, that comprises the molecular chaperones HspA8/Hsc70 and Hsp8B/Hsp22 and the cochaperones Bag3 and STUB1/CHIP, were studied by molecular, microscopic and submicroscopic investigations. CASA complex was found to be constitutively expressed in healthy bovine urothelium; its expression increased in urothelial cancers of cattle, namely thirteen papillary carcinomas and two papillary urothelial neoplasm of low malignant potential (PUNLMPs). We suggest that basal levels of CASA are important in the healthy urothelium which interfaces with the community of urinary microbiota thus representing an important epithelial cell-autonomous mechanism of antibacterial defense. Co-immunoprecipitation studies using an antibody against bovine papillomavirus E5 protein revealed that the oncoprotein co-localized with CASA complex in urothelial cancer cells. This suggests that infection by BPV E5 could influence cell behaviour by interfering with basal autophagy processes although this study did not conclusively show that this interaction increased the expression of CASA proteins. In neoplastic urothelium, CASA could be involved in regulating fundamental cellular processes such adhesion, migration, and proliferation and so might influence the biological behaviour of urothelial tumors in cattle.

Abstract
Aims and Background An association between human papilloma virus (HPV) and bladder cancer has been reported. However, the role of HPV in bilharzial bladder cancer and its prevalence have not yet been clarified. Study design We investigated 50 cases for HPV types 16/18 by in situ hybridization. Also, p53 protein expression by immunohistochemistry was evaluated in 41 of the 50 cases, with correlation of these factors to clinicopathologic parameters and tumor relapse after primary treatment. Results HPV was detected in 46% of Egyptian bladder carcinomas (23/50 cases). Positivity was 47.8% for squamous cell carcinoma and 36.4% for transitional cell carcinoma. There was a possible viral-bilharzial association as 52.8% of Bilharzial cases, whereas only 12.5% of non-Bilharzial cases were HPV positive (P <0.05). P53 protein was found in 19/41 (46.3%) cases. There was a concordance between HPV and p53 in 58.5% of cases. Neither factor was related to tumor recurrence after primary treatment. Conclusions HPV may thus be implicated in the etiology of bilharzial bladder cancer, but a definite causal relationship remains to be demonstrated. HPV together with p53 alterations work in synergy to accelerate the carcinogenic process, as there was concordance in the results of both parameters in 24/41 (58.5%) cases.

Abstract
Kaposi's sarcoma-associated herpesvirus (KSHV) is the major etiologic agent of Kaposi's sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. Recent studies have indicated that KSHV can be detected at high frequency in patient-derived bladder cancer tissue and might be associated with the pathogenesis of bladder cancer. Bladder cancer is the second most common cancer of the genitourinary tract, and it has a high rate of recurrence. Because drug resistance is closely related to chemotherapy failure and cancer recurrence, we investigated whether KSHV infection is associated with drug resistance of bladder cancer cells. Some KSHV-infected bladder cancer cell lines showed resistance to an anti-cancer drug, cisplatin, possibly as a result of down-regulation of reactive oxygen species. Additionally, drug resistance acquired from KSHV infection could partly be overcome by HDAC1 inhibitors. Taken together, the data suggest the possible role of KSHV in chemo-resistant bladder cancer, and indicate the therapeutic potential of HDAC1 inhibitors in drug-resistant bladder cancers associated with KSHV infection.

Abstract
Currently, debate continues about the etiological role of pathogens, in particular viruses, in the development of bladder tumors, their impact on the rate of recurrence and invasive and metastatic forms. The etiological role of high-risk human papillomavirus (HPV) in squamous carcinoma of the cervix and upper respiratory tract is considered proven. However, some published studies show the role of oncogenic HPV in causing bladder cancer, its invasiveness and metastasizing. The review is dedicated to examining the role of HPV in the carcinogenesis of bladder cancer.

Abstract
Therapeutic intervention using oncolytic viruses is called virotherapy. This type of virus is defined by the ability to replicate in tumor cells only and to destroy these cells upon replication. In addition, this virus type is able to induce a tumor-directed immune response. Early clinical trials have confirmed the safety profile of oncolytic viruses. Currently, different groups are working on the development of oncolytic viruses with a focus on treatment of nonmuscle invasive bladder cancer (NMIBC). A preliminary active recruiting clinical phase II/III trial ongoing in patients with a NMIBC was recently implemented in the United States. Our research group developed an oncolytic adenovirus that will soon enter a clinical phase I trial in patients diagnosed with glioma. This virus is being further modified for the treatment of NMIBC. In this review article, recent developments in the design and use of virotherapy in bladder cancer are summarized.

Abstract
Background Mincle, macrophage-inducible C-type lectin, is a member of C-type lectin receptors. It plays an important role in anti-mycobacterial and anti-fungal immunity. Furthermore it senses dead cells through its primary ligand SAP130. Materials and Findings We examined ten urothelial tumors of the urinary bladder of cattle. Eight of them expressed E5 cDNA of bovine papillomaviruses type 2 (BPV-2) and type 13 (BPV-13) that belong to Deltapapillomavirus genus. Two of them were not examined for detection of E5 cDNA. Mincle expression appeared to occur in urothelial neoplastic cells only. No mincle expression was detected in urothelial cells from healthy cattle. Mincle expression was characterized by a membranous pattern in papillary urothelial cancers; isolated and/or clustered urothelial cells showing a strong cytoplasmic immunoreactivity were primarily seen in invasive urothelial cancers. Conclusion This is the first study about the expression of mincle in veterinary oncology and the first report which describes the expression of functional mincle receptor in neoplastic cells in medical literature. As it has been shown that urothelial cancer cells have the ability to function as antigen-presenting cells (APCs), it is conceivable that mincle expression is involved in the presentation of cancer cell antigens to cells of the immune system. Furthermore, since expression of mincle contributes to the control of Mycobacterium bovis BCG infection, this study has exciting clinical implications in comparative medicine keeping in mind that Bacillus Calmette-Guérin (BCG) immunotherapy is currently the most effective treatment of non-muscle invasive bladder cancer in man. Mincle expression in urothelial tumor cells warrants further study to better understand the role, if any, of this receptor in bladder cancer. Future studies will provide insights in the role of mincle receptor of urothelial cancer cells in antitumor immunotherapy.

Abstract
Bladder cancer is universally acknowledged as a significant public health issue. Abundant evidence shows that cigarette smoke (CS) is the primary risk factor for bladder cancer. However, the mechanism of CS-induced bladder cancer has not been fully elucidated. CS-induced epithelial-mesenchymal transition (EMT) is critically involved in cell malignant transformation. The role of ERK5, the lesser studied member of the MAPK family, in regulating CS-triggered EMT has not yet been investigated. The objective of the present study was to investigate the regulatory role of ERK5 in CS-induced urocystic EMT. SV-40 immortalized normal human urothelial cells (SV-HUC-1) were used as in vitro CS exposure models. EMT phenotypic alterations were assessed by changes in cell morphology, invasive capacity, as well as expression of epithelial and mesenchymal markers. Protein and mRNA expression levels were analyzed by western blotting and quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). ERK5 inhibition studies were performed with a specific inhibitor. Exposure of SV-HUC-1 cells to CS induced morphological change, enhanced invasive capacity, reduced epithelial marker expression and increased mesenchymal marker expression. Importantly, we demonstrated for the first time that ERK5 positively regulated CS-mediated EMT in urothelial cells, as evidenced by the findings that CS promoted ERK5 activation, and that the CS-triggered alteration in the EMT phenotype was reversed by ERK5 inhibition.

Abstract
The anti-tuberculosis-vaccine Bacillus Calmette-Guérin (BCG) is the most widely used vaccine in the world. In addition to its effects against tuberculosis, BCG vaccination also induces non-specific beneficial effects against certain forms of malignancy and against infections with unrelated pathogens. It has been recently proposed that the non-specific effects of BCG are mediated through epigenetic reprogramming of monocytes, a process called trained immunity. In the present study we demonstrate that autophagy contributes to trained immunity induced by BCG. Pharmacologic inhibition of autophagy blocked trained immunity induced in vitro by stimuli such as β–glucans or BCG. Single nucleotide polymorphisms (SNPs) in the autophagy genes ATG2B (rs3759601) and ATG5 (rs2245214) influenced both the in vitro and in vivo training effect of BCG upon restimulation with unrelated bacterial or fungal stimuli. Furthermore, pharmacologic or genetic inhibition of autophagy blocked epigenetic reprogramming of monocytes at the level of H3K4 trimethylation. Finally, we demonstrate that rs3759601 in ATG2B correlates with progression and recurrence of bladder cancer after BCG intravesical instillation therapy. These findings identify a key role of autophagy for the nonspecific protective effects of BCG. Next to its effects against tuberculosis, BCG vaccination also induces non-specific beneficial effects on immune cells to increase their ability to control unrelated pathogens. It has been recently proposed that the non-specific effects of BCG are mediated through epigenetic reprogramming of monocytes, a process called trained immunity. Little is known regarding the intracellular events controlling its induction. In this study we identified autophagy as a key player in trained immunity. Pharmacological inhibition of autophagy as well as polymorphisms in autophagy-related genes blocked BCG-induced trained immunity. Furthermore, BCG vaccine is also used to treat bladder cancer. Genetic polymorphisms in autophagy-related genes correlated with progression and recurrence of bladder cancer after treatment with BCG therapy. These findings open new possibilities for improvement of future BCG-based vaccines to be used against infections and malignancies.

Abstract
OBJECTIVES To determine the potential association between HPV infection and the squamous cell component of urothelial carcinoma (UC) of the bladder and to validate p16 overexpression as a surrogate marker for HPV infection in these cancers among Koreans. METHODS We analyzed the presence of HPV infection using an HPV-DNA chip and the expression of p16 using immunohistochemistry in 47 subjects between July 2001 and March 2011. The study group (n = 35) included patients with squamous differentiation of UC of the bladder. The control group (n = 12) included patients with squamous metaplasia of the bladder. RESULTS Baseline characteristics of control and study groups were similar. HPV DNA detection rates were approximately 2-fold higher in the study than the control group (17.1% [6/35] versus 8.3% [1/12], respectively), but the difference was not statistically significant. P16 overexpression was detected in 16/35 (45.7%) study group and 1/12 (8.3%) control group samples (p = 0.034). Both HPV-positivity and p16 overexpression were present in 3/35 (8.8%) study group samples, but none of the control group (p = 0.295). In the study group, the percentage of HPV-positive cases who were non-smokers was 2-fold higher than the percentage of HPV-negative cases who were non-smokers (66.7% [4/6] versus 31.0% [9/29], respectively); however, statistical significance was not achieved due to the small sample size. CONCLUSIONS HPV infection may be associated with UC of the bladder with squamous differentiation, especially in non-smokers. However, p16 expression does not appear to be a strong surrogate marker for evidence of HPV infection in this type of cancer.

Abstract
Urothelial carcinoma of the bladder is a common malignancy that causes approximately 150,000 deaths per year worldwide. So far, no molecularly targeted agents have been approved for treatment of the disease. As part of The Cancer Genome Atlas project, we report here an integrated analysis of 131 urothelial carcinomas to provide a comprehensive landscape of molecular alterations. There were statistically significant recurrent mutations in 32 genes, including multiple genes involved in cell-cycle regulation, chromatin regulation, and kinase signalling pathways, as well as 9 genes not previously reported as significantly mutated in any cancer. RNA sequencing revealed four expression subtypes, two of which (papillary-like and basal/squamous-like) were also evident in microRNA sequencing and protein data. Whole-genome and RNA sequencing identified recurrent in-frame activating FGFR3-TACC3 fusions and expression or integration of several viruses (including HPV16) that are associated with gene inactivation. Our analyses identified potential therapeutic targets in 69% of the tumours, including 42% with targets in the phosphatidylinositol-3-OH kinase/AKT/mTOR pathway and 45% with targets (including ERBB2) in the RTK/MAPK pathway. Chromatin regulatory genes were more frequently mutated in urothelial carcinoma than in any other common cancer studied so far, indicating the future possibility of targeted therapy for chromatin abnormalities.

Abstract
Background Papillomaviruses (PVs) are highly epitheliotropic as they usually establish productive infections within squamous epithelia of the skin, the anogenital tract and the oral cavity. In this study, early (E) and late (L) protein expression of bovine papillomavirus type 2 (BPV-2) in the urothelium of the urinary bladder is described in cows and water buffaloes suffering from naturally occurring papillomavirus-associated urothelial bladder tumors. Methods and Findings E5 protein, the major oncoprotein of the BPV-2, was detected in all tumors. L1 DNA was amplified by PCR, cloned and sequenced and confirmed to be L1 DNA. The major capsid protein, L1, believed to be only expressed in productive papillomavirus infection was detected by Western blot analysis. Immunohistochemical investigations confirmed the presence of L1 protein both in the cytoplasm and nuclei of cells of the neoplastic urothelium. Finally, the early protein E2, required for viral DNA replication and known to be a pivotal factor for both productive and persistent infection, was detected by Western blot and immunohistochemically. Electron microscopic investigations detected electron dense particles, the shape and size of which are consistent with submicroscopic features of viral particles, in nuclei of neoplastic urothelium. Conclusion This study shows that both active and productive infections by BPV-2 in the urothelium of the bovine and bubaline urinary bladder can occur in vivo.

Abstract
Polyomaviruses are able to drive malignant transformation in rodent models, and have been implicated in the aetiology of a variety of human malignancies. However, the reports on this association in humans are strongly conflicting. Here we describe a renal transplant (RT) recipient with ureteral stenosis against the background of polyomavirus BK (BKV) activity. Six and a half years after transplantation, this patient developed metastasised bladder cancer. Prior to the diagnosis of cancer, atypical cells were detected in the urine that were denoted as 'decoy cells': virally infected epithelial cells that are frequently seen in the urine of RT recipients with BKV (re)activation, which may morphologically resemble malignant cells. Intriguingly, the primary urothelial carcinoma, as well as the mesenterial and two intestinal metastases, stained positive with antibodies against polyomavirus virus large T antigen protein, whereas the adjacent healthy tissue did not. This case suggests a role for BKV in the pathogenesis of bladder cancer, at least in the context of immunodeficiency.

Abstract
Abnormal heat shock protein (HSP) levels have been observed in a number of human tumours, where they are involved in all hallmarks of cancer. Since bovine urothelial tumours share striking morphological and biochemical features with their human counterparts, the aim of this study was to evaluate the immunohistochemical levels of Hsp27, Hsp60, Hsp72, Hsp73 and Hsp90 in 28 normal bovine urinary bladders and 30 bovine papillomavirus-positive urothelial tumours (9 in situ carcinomas, 9 low-grade and 12 high-grade carcinomas) and adjacent premalignant lesions obtained from cows suffering from chronic enzootic haematuria, in order to investigate the role of these proteins in the process of urothelial carcinogenesis. A semi-quantitative method was used for the analysis of the results. Western blot analysis was also used to confirm HSP expression in normal controls. All investigated HSPs were expressed in normal bovine urothelium, showing characteristic patterns of immunolabelling throughout urothelial cell layers, which usually appeared to be conserved in urothelial hyperplasia and dysplasia. On the other hand, gradual loss of Hsp27 immunostaining resulted to be significantly associated with increasing histological grade of malignancy (P < 0.01). As well, a significantly reduced immunosignal of Hsp73 and Hsp90 was observed in high-grade and low-/high-grade carcinomas, respectively (P < 0.01). In contrast, Hsp60 (P < 0.01) and Hsp72 (P < 0.05) immunoreactivity appeared to be significantly increased both in premalignant and malignant lesions when compared to that observed in normal urothelium, thus suggesting an early involvement of these proteins in neoplastic transformation of urinary bladder mucosa.

Abstract
BACKGROUND Nested variant of urothelial carcinoma (NVUC) is a rare and often unrecognized urothelial neoplasia. Diagnosis is based on morphology only, and no immunohistochemical or cytogenetic differences from usual high-grade urothelial carcinomas have been reported. CASE We describe the case of a 49-year-old woman affected by hepatitis C virus presented with fever, discomfort, urgency, and hypertension. Computed tomography showed a sclerosing inflammatory process involving the connective and adipose tissue of the renal sinus. In the absence of renal or pelvic masses an underlying malignancy was excluded and renal abscess or tuberculosis was suspected. Accordingly, nephrectomy and proximal ureterectomy was performed. Grossly, calices, renal pelvis, and pyeloureteral junction appeared modestly dilated with whitish, thickened, and uneven mucosa. Microscopically, the subepithelial connective tissue, the fibromuscular layer, and the renal sinus fat were diffusely infiltrated by small nests of medium to large urothelial cells (p63 positive) with abundant eosinophylic cytoplasm and slightly atypical nuclei. CONCLUSION On the basis of morphologic and immunohistochemical features, a diagnosis of NVUC was made. After surgery, the patient recovered from hypertension. Pelvic and upper urothelial tract NVUCs are uncommon, and to the best of our knowledge, this is the second case of NVUC with renal involvement.

Abstract
OBJECTIVE To explore the association between urothelial carcinoma following renal transplantation and infection by human papillomavirus (HPV) types 16 and 18. MATERIALS AND METHODS Of 3780 patients who underwent renal transplantation, we identified 90 cases of urothelial carcinoma. Tumor tissues collected from the 90 renal transplant recipients were compared with those from 30 nontransplanted patients with bladder cancer (control group) for HPV types 16 and 18 using polymerase chain reactions. RESULTS Seven transplanted patients were HPV positive: HPV-16 was detected in 3 patients with bladder cancer (3/90; 3.3%), and HPV-18 in 2 patients with bilateral pelvic ureteral carcinoma (2/90; 2.2%), and 2 patients with bladder cancer (2/90; 2.2%). Only 2 cases from the control group were HPV positive (both HPV-18; 2/30; 5%). The difference between the RTR and control groups was not significant (P > .05). CONCLUSION Malignant tumors in the urinary system following renal transplantation did not seems to be associated with infection by HPV-16 or -18.

Abstract
A female patient with recurrent bladder cancer underwent complex examination. The primary tumor removed in 2004 showed human papillomavirus (HPV) 16 DNA, mRNA corresponding to HPV16 oncogene E7, as well as HPV16 protein E7. The patient is a smoker who has been working at a chemical factory for over 20 years. During tumor recurrence in 2009, there was no DNA of high-risk HPV types in the cancer cells. HPV16 E7protein and cellular p 16(INK4alpha), an indicator of HPV-induced carcinogenesis, were not found. Colposcopy revealed no precancerous changes in the epithelium of the cervix uteri. The cervical epitheliocytes contained no high-risk HPV DNA, E7 and p16(INK4alpha) proteins. It seems expedient to continue in vitro studies of the possible role of HPV in urothelial carcinogenesis on an experimental model.

Abstract
Background Calpain 3 (Capn3), also named p94, is a skeletal muscle tissue-specific protein known to be responsible for limb-girdle muscular dystrophy type 2A (LGMD2A). Recent experimental studies have hypothesized a pro-apoptotic role of Capn3 in some melanoma cell lines. So far the link between calpain3 and tumors comes from in vitro studies. The objective of this study was to describe Capn3 activation in naturally occurring urothelial tumors of the urinary bladder in cattle. Methods and Findings Here we describe, for the first time in veterinary and comparative oncology, the activation of Capn3 in twelve urothelial tumor cells of the urinary bladder of cattle. Capn3 protein was initially identified with nanoscale liquid chromatography coupled with tandem mass spectrometry (nano LC-MS/MS) in a co-immunoprecipitation experiment on E2F3, known to be a transcription factor playing a crucial role in bladder carcinogenesis in humans. Capn3 expression was then confirmed by reverse transcription polymerase chain reaction (RT-PCR). Finally, the Ca2+-dependent proteolytic activity of Capn3 was assayed following ion exchange chromatography. Morphologically, Capn3 expression was documented by immunohistochemical methods. In fact numerous tumor cells showed an intracytoplasmic immunoreactivity, which was more rarely evident also at nuclear level. In urothelial tumors, bovine papillomavirus type 2 (BPV-2) DNA was amplified by PCR and the expression of E5 protein, the major oncogenic protein of BVP-2, was detected by western blotting, immunohistochemistry, and immunofluorescence. E2F3 overexpression and pRb protein downregulation were shown by western blotting. Conclusion The role of capn3 protein in urothelial cancer of the urinary bladder remains to be elucidated: further studies would be required to determine the precise function of this protease in tumor development and progression. However, we suggest that activated Capn3 may be involved in molecular pathways leading to the overexpression of E2F3, which in turn could be responsible for urothelial tumor cell proliferation also in cattle, though other mechanisms are likely to exist. If further studies corroborate the important role of Capn3 in urothelial tumors of the urinary bladder, cattle with urinary tumors may prove useful as animal model for bladder carcinogenesis.

Abstract
Oncoprotein E7 HPV16 was detected by immunohistochemical staining with specific polyclonal antiserum [Fiedler et al., 2004] in 7 out of the 24 (29.2%) studied bladder cancer specimens. The result is in good agreement with the hypothesis that HPVs take part in the carcinogenesis of the urothelium. However, some of the observations made seem rather hard to be interpreted at present. The latter include the detection of E7 HPV16 in a small number of cancer cells in a few bladder cancer specimens being examined; the presence of this protein in the cytoplasm, rather in the cancer cell nuclei, and its detection in some morphologically normal bladder urothelial specimens from non-cancer patients. Thus, the hypothesis that HPVs are implicated in the carcinogenesis of the bladder urothelium deserves further verification.

Abstract
BACKGROUND Bladder cancer is a common malignancy in Egypt. Human papillomavirus (HPV) could have a possible etiologic role in bladder carcinogenesis. We aimed to estimate the prevalence of HPV-16, -18, and -52 in Egyptian patients with bladder cancer or recurrent cystitis, and to study the correlation of type-specific HPV-immunoglobulin (Ig)G with polymerase chain reaction (PCR) results and different clinicopathologic parameters. METHODS This study was conducted on 60 inpatients of the Urosurgery Department at the Theodor Bilharz Research Institute (TBRI), who were identified histopathologically and clinically as cancer bladder (group I, 20 patients), cystitis (group II, 24 patients), and cancer bladder with cystitis (group III, 16 patients), and a fourth group of 20 healthy control subjects (for serologic testing). Patients were subjected to detection of HPV-16 and -18 DNA by PCR on bladder tissue biopsies (BTB) and buffy coat cells (BCC) and serum IgG antibodies to L1 capsids of HPV-16 and -52 IgG by enzyme-linked immunosorbent assay (ELISA). RESULTS HPV-16 and -18 DNA were detected in BTB (30% and 10%, respectively) with significantly higher rates (44.4%) in bladder cancer than cystitis cases (11.11%), with significant association with schistosomal affection (78.6% and 25%, respectively) and recurrence (48%, HPV-16). There was a significant association of transitional cell carcinoma (TCC) with HPV-16 in 69.2% and 61.1% of BCC and BTB, respectively. Multiple HPV types 16, 18, and 52 were significantly higher than single types (79.2% and 20.8%, respectively). The observed absolute association between seropositivity of HPV-52 (11.7%) and HPV-16 (26.7%) was significantly associated with TCC in patient groups only. CONCLUSION Our study confirmed the significant association of HPV-16, -18 and -52 with bladder cancer in Egyptian patients, with the suggestion of viral synergistic action in bladder carcinogenesis. Such HPV types were significantly associated with TCC tumors of low grade and high stage, with schistosomal affection and recurrence tendency. HPV serology would pave the way for better management and follow-up of patients and for optimal design and evaluation of HPV vaccination.

Abstract
Early pathological changes of Bovine papilloma virus (BPV-2)-fern (Pteridium aquilinum and Onychium contiguum fern) interaction in hamsters were studied. In bracken-exposed cattle, BPV induces malignancy in gastrointestinal and urinary bladder mucosa. Cutaneous warts were transmitted successfully in hamsters approximately after 3 months post inoculation while urinary bladder tumour of enzootic bovine haematuria cases were not transmitted. Histologically, tumour was diagnosed as fibroma. Onychium produced more pronounced effects than bracken fern which was characterized by significant reduction in body weight and testicular atrophy. BPV-fern interaction was not appreciable during early period of tumour induction and requires long-term studies for 12 to 18 months.

Abstract
This study was based on 30 papillomavirus-associated urinary bladder tumours from cattle with chronic haematuria, the animals having been kept since birth on pasture rich in bracken fern. The ganglioside content was assessed and compared with that of normal bovine urinary bladders, which was shown to be 28.6+/-3.3 (mean+/-SD) microg of lipid-bound sialic acid per gram of fresh tissue. In neoplastic bladder samples this value was higher but variable (120.9+/-80.6 in benign tumours, and 94.7+/-45.7 in malignant tumours). The main ganglioside, GM3, represented ca 75% of the total ganglioside mixture in normal tissues and 50-80% in tumour samples. GM1, GM2, GD1a, GD3 and FucGM1 were found as minor components. The study suggested that GM3 ganglioside may have a crucial role in "downregulation" of the metastatic potential of bovine urothelial cancers.

Abstract
There have been few studies regarding the etiology of renal cell carcinoma. To examine the possible involvement of Epstein-Barr virus (EBV) in this disease, 9 renal cell carcinoma (RCC), 2 nephroblastoma (Wilms' tumor) and 2 RCC cell lines were subjected to mRNA in situ hybridization and indirect immunofluorescence staining. Messenger RNA in situ hybridization using BamHIW, EBNA LP, EBNA 2 and EBER1 probes of EBV revealed signals in all the examined samples, although some samples showed weak signals using the EBNA LP probe. Indirect immunofluorescence staining using anti-EBNA LP, anti-EBNA2, anti-LMP1 and anti-BZLF1 antibodies showed definitive fluorescence. PCR also revealed EBV DNA in all 8 RCC specimens including 7 cases other than hybridization and fluorescence. EBV infected all the RCC and nephroblastoma irrespective of the histological or clinical stage. On the other hand, EBV expression was stronger in papillary and clear cell-type RCC than chromophobe cell-type, as well as being stronger in the higher grades of RCC. These results suggest that the expression of EBV may be involved in the pathogenesis of RCC and nephroblastoma.

Abstract
Cattles suffering from chronic enzootic haematuria frequently develop urinary bladder tumours of both epithelial and mesenchymal origin mainly haemangioma and its malignant counterpart. The role of the bovine papillomavirus type-2 (BPV-2) and of its major transforming oncoprotein in naturally occurring urothelial carcinogenesis has been recently clarified. E5 interacts in vivo as in vitro with the beta receptor for the platelet-derived growth factor (PDGF). However, studies regarding tumours of mesenchymal origin such as those arising from blood vessels are lacking. We show that the BPV-2 is present in 100% of the vascular tumours of the urinary bladder examined. Twenty-six out of twenty-seven tumour samples (96%) expressed E5 while 20 out of 27 (74%) tumour samples expressed E7. The two viral oncoproteins were not expressed in normal endothelial cells. Additionally, they co-localize in neoplastic endothelial cells as demonstrated by confocal immunofluorescence. PDGFbeta receptor was also shown to be expressed and co-localizes with E5 in neoplastic blood vessels. Our results demonstrate, for the first time, that the BPV-2 is present in high percentage in tumours of mesenchymal origin arising in its natural host. Furthermore, the expression of the two viral oncoproteins confirm that the virus may have a causative role in the neoplastic process.

Abstract
BK virus (BKV), a common human polyomavirus infection latent in the kidneys, can reactivate with immunosuppression to cause renal disease. Some have suggested that BKV may contribute to the development of bladder cancer, and BKV sequences have been reported from bladder tumors. To further examine the role of BKV in human bladder cancer, a series of bladder tumors was investigated for BKV genomic sequences. Fresh-frozen specimens from 76 transitional cell carcinoma tissues and 46 paired adjacent normal urothelial tissues archived at the H. Lee Moffitt Cancer Center were studied. All tissues were histopathologically reviewed. DNA extracted from the tissues was tested by quantitative real-time polymerase chain reaction (QPCR) assays to detect BKV DNA sequences in the VP1 coding region. Amplification of ERV-3 was conducted separately to quantify cell copy number. Conventional PCR targeting the BKV T-antigen (T-Ag) coding region and immunohistochemistry for BKV T-Ag were also conducted on all tissues that tested positive for BKV by QPCR. Seventy-three bladder tumors yielded >/=3,000 copies of ERV-3, 4 (5.5%) of which tested positive for BKV with average copy numbers of 7.9, 15.8, 0.4 and 0.3 per 1,000 cells. Paired normal tissue was available for 2 of these BKV-positive tumors, 1 of which was BKV-positive (14.6 copies/1,000 cells). No other normal tissues were BKV-positive by QPCR. The 6 BKV-positive tissues by QPCR were also positive by conventional PCR, but all stained negative for BKV T-Ag by immunohistochemistry. BKV is unlikely to be involved in the etiology of most bladder tumors.

Abstract
INTRODUCTION The bladder cancer is an important disease by its morbi-mortality and its multifactorialidad. At the moment, between the possible aetiology agents that they have been indicated is the infection by the virus of papilloma human (VPH). The objective study is to analyse, by meta-analysis, the relationship between bladder cancer and infection by human papillomavirus. MATERIAL AND METHODS We made a search in the electronic data base MEDLINE of the articles published until September of the 2004 that relate the infection of the VPH to the bladder tumors. Of 414 listed articles, we selected 38 articles. RESULTS The articles were classified in two groups, according to they use or non methods based on the detection of the DNA. In articles based on the detection of the DNA, it was that the global proportion from the cases that had contact with the virus, through the detection of the genome was of the 19.4% (95% CI 0.160 to 0.228). Of the total of studies based on the detection of the DNA 8 were selected, to show to a group defined control, in which, the OR was investigated. If we combined the ORs, we obtain an OR estimation of 3.2 (95% CI 1.19 to 8.60) and p = 0.02. CONCLUSIONS Most of these studies showed the relation rose at the beginning of the study. Although the majority lacked a group defined control, is possible to analyze the value of the Odds global ratio due to the homogenous behaviour of the studies with defined cases and controls affluent. This demonstrated to association between VPH and the bladder cancer.

Abstract
PURPOSE Studies have been done of the possibility that infection by human papillomavirus is a risk factor contributing to bladder cancer but no definite conclusions have yet been drawn. We performed a meta-analysis of observational studies published until July 2005 to ascertain the degree of association between bladder cancer and human papillomavirus infection. MATERIALS AND METHODS The MEDLINE database was searched using the key words bladder cancer and virus. Strict criteria were applied to select studies revealing the prevalence in serum of human papillomavirus infection or its direct detection in patients. A total of 44 articles with these methodological criteria were chosen. RESULTS In 39 studies the investigators determined the presence of human papillomavirus DNA, and found a prevalence of between 0% and 100% and significant homogeneity analysis (p <0.001). Pooled estimation of the presence of the infection was 16.0% (95% CI 12.8 to 19.1). Pooled OR estimation was 2.3 (95% CI 1.3 to 4.1) with no significant publication bias. In 7 studies human papillomavirus infection was studied by detecting the antigen or antibodies and a prevalence of between 14% and 60% was found with significant homogeneity analysis (p <0.001). Pooled estimation of the prevalence of infection was 32.4% (95% CI 17.0 to 47.8). Pooled OR estimation was 2.9 (95% CI 1.7 to 5.3). CONCLUSIONS Finding a relationship between bladder cancer and human papillomavirus depends on the method used. In the literature examined there are insufficient cases and samples compared to controls and studies rely on a combination of various microbiological techniques in the same patient and sample, making it difficult to draw any definite conclusion.

Abstract
Bovine papillomavirus (BPV) type 2 is involved in carcinogenesis of the urinary bladder in cattle, while BPV-1 is commonly associated with equine sarcoid tumours. In both cases the early viral proteins are expressed, but virion is not produced. Given the similarities in BPV biology between the tumours in cattle and horses, bovine bladder cancers and equine sarcoids were compared with respect to physical status, load of viral DNA and variability of the E5 open reading frame (ORF). Rolling circle amplification demonstrated that BPV-1 and BPV-2 genomes exist as double stranded, episomal, circular forms in the two tumours. Realtime quantitative PCR revealed that equine sarcoids contained higher viral DNA loads compared to bovine bladder cancers. The BPV-1 E5 ORF showed sequence variation but BPV-2 ORF did not. The presence of BPV-1 E5 variations or their absence in the BPV-2 E5 ORF does not appear to have an effect on viral DNA load in either tumour type.

Abstract
OBJECTIVES High-risk human papilloma virus (HPV) types stimulate degradation and deactivation of protein associated with the p53 tumour suppressor gene via the ubiquitin-dependent pathway. For a long time, changes of the p53 tumour suppressor gene have been correlated with poor clinical outcome in patients with superficial bladder cancer. We aimed to study the association between presence of (high-risk) HPV DNA, p53 status, and clinical outcome in bladder cancer patients. This study must be seen as a preliminary study to investigate this potentially important problem. MATERIAL AND METHODS From 107 patients, 166 bladder wash samples were obtained. p53 status was determined by mutation analysis, HPV detection, and genotyping by the SPF(10)-LiPA assay. Clinical data were abstracted from the medical files. RESULTS The prevalence of all-type and high-risk HPV infection in malignancies of the bladder was 15.2% and 8.1%, respectively. In high-grade tumours this prevalence was 18.2% and 10.6%, respectively. In grade 1, 2 and 3 tumours the infection rate of high-risk HPV types was 0%, 3.3%, and 10.6%, respectively (trend test: p=0.221). In Ta, T1, and T2-T4 tumours the high-risk HPV infection rate was 0%, 12.5% and 18.2%, respectively (trend test: p=0.045). In the p53 wild-type patients who showed progression, 1 of 9 patients had a high-risk type HPV infection. In the group of wild-type patients who showed no progression, 4 of 37 patients had a high-risk type HPV infection (odds ratio: 1.03; 95% confidence interval, 0.1-10.5). CONCLUSIONS The data of this pilot study show the suggestion of a positive trend in the correlation between tumour grade/stage and high-risk type HPV infection. However, no additional risk for progression is found for p53 wild-type patients with a high-risk HPV infection.

Abstract
OBJECTIVE To evaluate the effect of combined use of oncolytic virus and the chemotherapeutic agents mitomycin (MMC) in growth inhibition of human bladder cancer cell line T-24 in vitro. METHODS Human bladder cancer cell line T-24 was infected with oncolytic virus (ONYX-015) of different multiplicity of infection, or treated with MMC in addition to ONYX-015. The changes in the cell growth, morphology, and apoptosis of cultured T-24 cells were observed by means of cell counting and fluorescence microscopy after the treatments. The effects of the treatment protocols were also tested in nude mouse model of implanted subcutaneous tumor. RESULTS Combined use of ONYX-015 and MMC produced substantially stronger cytotoxic effect against T-24 cells than exclusive use of ONYX-015. In in vivo experiments, combination of oncolytic virus and MMC resulted in much more significant tumor growth inhibition than either of the agents used alone. Obvious T-24 cell apoptosis could be observed in response to combined ONYX-105 and MMC treatment and exclusive ONYX-105 treatment. CONCLUSIONS ONYX-015 combined with MMC can produce significant cytotoxicity against T-24 cells and enhance therapeutic efficacy against bladder carcinoma.

Abstract
OBJECTIVES To address whether Epstein-Barr virus (EBV) infection may be involved in the carcinogenesis of squamous cell carcinoma of the upper urinary tract and urinary bladder (SCC-UB). EBV has been implicated in the genesis of a variety of human cancers, including urothelial carcinoma of the urinary bladder. METHODS Whether EBV infection is related to SCC-UB carcinogenesis was investigated by in situ hybridization for EBV-encoded RNA and immunohistochemistry for latent membrane protein-1 in 26 cases of SCC-UB. RESULTS EBV-encoded RNA and latent membrane protein-1 were identified in the control case of nasopharyngeal carcinoma. None of the SCC-UB cases had a nuclear signal of EBV-encoded RNA, and the cancer cells, normal urothelial cells, and inflammatory cells were all negative for latent membrane protein-1, irrespective of the site of SCC-UB. CONCLUSIONS This study is the first to explore the role of EBV infection in SCC-UB. Our results suggest that EBV infection is not involved in the carcinogenesis of SCC of the renal pelvis, ureter, and urinary bladder.

Abstract
The aim of the current study was to compare the role of p53 and human papillomavirus (HPV) in schistosomiasis-related and schistosomiasis-unrelated carcinoma of the urinary bladder. To achieve this aim, we investigated 114 bladder carcinomas for p53 oncoprotein expression by immunohistochemistry and for human papillomavirus by in situ hybridization technique. The results revealed that 64 tumors (56.1%) were schistosomiasis-associated. Sixty seven (58.8%) were transitional cell carcinomas and 32 (28%) were squamous cell carcinomas. The remaining 15 tumors (13.2%) included adenocarcinomas and sarcomatoid carcinomas. In both schistosomiasis-associated and non-associated carcinomas, p53 oncoprotein expression was significantly higher in poorly differentiated tumors. However, it was significantly higher in locally more invasive tumors in the schistosomal carcinomas only. HPV types 16/18 could be detected in 1 of the 114 bladder carcinomas (0.95%), which was schistosomiasis-related squamous cell carcinoma in situ. These results suggest that p53 immunohistochemistry can be a prognostic factor in both schistosomal and nonschistosomal bladder cancer. More importantly, HPV does not seem to play a role in the pathogenesis of either type of bladder cancer in our country.

Abstract
Several immunohistochemical markers have been used to define the differentiation pattern of urothelial cell tumors of the urinary bladder. We investigated the expression of the recently characterized uroplakin (UP) IIIb, an urothelium-specific and differentiation-dependent protein, in 39 urothelial tumors of the urinary bladder in cows that had suffered from chronic enzootic hematuria for several years. Bovine papillomavirus type 2 DNA was amplified and UP IIIb protein was detected in all these tumors. In papillomas and papillary carcinomas, UP IIIb expression was mostly seen as superficial staining; luminal and peripheral patterns were also observed. In nonpapillary carcinomas, UP IIIb appeared to define clearly the cell membrane lining intercellular and intracellular lumina as well as the cell borders in deeper cell layers. In benign and malignant lesions, an intracytoplasmic immunoreactivity was also detected. Coarse intracytoplasmic UP IIIb-positive material close to the nucleus occurred in some malignant cells. Focally strong membraneous immunostaining that marked single cells with complete ringlike peripheral pattern was seen. Although UP IIIb expression does not seem to correlate with the biological behavior of urothelial tumors, it appears to be a highly sensitive marker for bovine urothelial tumors.

Abstract
Noninvasive squamous lesions are distinctively uncommon in biopsies of the urinary bladder with the exception of nonkeratinizing squamous metaplasia. The clinical significance of these squamous lesions in the bladder remains to be explored. A total of 29 cases of transurethral biopsies and resections of the bladder containing noninvasive squamous lesions (excluding nonkeratinizing metaplasia) were studied from the consult files of one of the authors. These cases included keratinizing squamous metaplasia (5), verrucous squamous hyperplasia (5), squamous papilloma (5), condyloma acuminatum (3), and squamous cell carcinoma in situ (CIS) (11). Immunohistochemistry for epithelial growth factor receptor (EGFR) and in situ hybridization for wide-range human papillomavirus was performed on 23 cases. The follow-up period ranged from 2 months to 3 years with an average of 1.5 years. After the initial diagnoses in biopsies of the bladder, 10 patients received cystectomies, and 7 patients received repeat tissue sampling of the bladder. Of the 5 patients with keratinizing squamous metaplasia, 2 patients had invasive urothelial carcinoma with squamous features in their cystectomy specimens at intervals of 3 and 14 months, respectively, 1 had persistent keratinizing squamous metaplasia on rebiopsy. Of the 5 patients with verrucous squamous hyperplasia, 1 patient had invasive squamous cell carcinoma at cystectomy at an interval of 14 months, 1 had squamous cell CIS on rebiopsy, 1 had persistent verrucous squamous hyperplasia on rebiopsy, and 2 had no evidence of disease at 6 and 24 months. Of the 5 patients with squamous papilloma, 1 patient had low-grade urothelial carcinoma at cystectomy at an interval of 21 months (h/o low-grade urothelial carcinoma preceding papilloma diagnosis), 2 were free of lesions at rebiopsy. Of the 3 patients with condyloma acuminatum, 1 had squamous CIS at cystectomy at an interval of 3 months, 1 had invasive squamous cell carcinoma at 20 months. Of the 11 patients with squamous cell carcinoma in situ (CIS), 3 patients had invasive squamous cell carcinoma at intervals of 2, 3, and 4 months, respectively, 1 had invasive urothelial carcinoma with squamous features in cystectomies at an interval of 12 months, 1 had squamous cell CIS at 10 months, 1 had high-grade urothelial carcinoma (not otherwise specified) at rebiopsy at an interval of 6 months, and 1 had no evidence of disease at 8 months. Among the 9 patients with invasive carcinoma, 4 patients died in the period of 0.5 to 3 years after the diagnoses. Immunohistochemical study with EGFR demonstrated strong signals in 20 cases and no signals in 2 cases. Wide-range human papillomavirus DNA signal was detected in 1 case of condyloma acuminatum and 1 case of squamous cell CIS. Keratinizing squamous metaplasia, verrucous squamous hyperplasia, and condyloma acuminatum in the urinary bladder can be associated with subsequent or concurrent in situ, or invasive squamous carcinoma and should be closely followed. Squamous cell CIS in the urinary bladder is often associated with subsequent or concurrent invasive carcinoma with squamous differentiation. Enhanced expression of EGFR in these bladder squamous lesions suggests that EGFR may represent a logic therapeutic target in those squamous lesions that are difficult to manage clinically.

Abstract
A clinicopathologic study of 108 cases of high-grade urothelial carcinomas of the renal pelvis is presented. Of the 108 tumors, 44 (40%) showed unusual morphologic features, including micropapillary areas (four cases), lymphoepithelioma-like carcinoma (two cases), sarcomatoid carcinoma (eight cases, including pseudoangiosarcomatous type), squamous differentiation and squamous cell carcinoma (15 cases), clear cells (two cases), glandular differentiation (two cases), rhabdoid, signet-ring or plasmacytoid cells (four cases), pseudosarcomatous stromal changes (four cases) and intratubular extension into the renal pelvis (three cases). Pathological staging was available in 62 patients; of these, 46 cases (74%) were in high stage (pT2-pT4) and 16 (26%) were in low stage (pTis, pTa, pT1). Clinical follow-up ranging from 1 to 256 months (median: 50 months) was available in 42 patients; of these, 26 (61%) died of tumor with a median survival of 31 months. The patients who did not die of their tumors showed only minimal or focal infiltration of the renal parenchyma by urothelial carcinoma, whereas those who died of their tumors showed massive infiltration of the kidney by the tumor. High-grade urothelial carcinomas of the renal pelvis can show a broad spectrum of histologic features similar to those seen in the urinary bladder. Our results support the finding that, unlike urothelial carcinomas of the bladder, the majority of primary urothelial carcinomas of the renal pelvis are of high histologic grade and present in advanced stages. Our study further highlights the fact that, in the renal pelvis, urothelial carcinomas show a tendency to frequently display unusual morphologic features and metaplastic phenomena. The importance of recognizing these morphologic variants of urothelial carcinoma in the renal pelvis is to avoid confusion with other conditions. The possibility of a high-grade urothelial carcinoma should always be considered in the evaluation of a tumor displaying unusual morphologic features in the renal pelvis, and attention to proper sampling as well as the use of immunohistochemical stains will be of importance to arrive at the correct diagnosis.

Abstract
Studies regarding the functions of the bovine papillomavirus (BPV) E5 oncoprotein in vivo are lacking and no E5-mediated mechanism underlying epithelial carcinogenesis is known. We have shown that BPV-2 DNA is present in the majority of naturally occurring urinary bladder tumours of cattle and that E5 is expressed in the cancer cells. Here we show that the interaction between the platelet-derived growth factor (PDGF) beta receptor and BPV E5, described in vitro in cultured cells, takes place in vivo in bovine urinary bladder cancers. In these cancers, E5 and PDGF beta receptor colocalize, as shown by confocal microscopy, and physically interact, as shown by coimmunoprecipitation. Furthermore, the PDGF beta receptor associated with E5 is highly phosphorylated, suggesting the functional activation of the receptor upon E5 interaction. Our results demonstrate, for the first time, that E5-PDGF beta receptor interaction occurs during the natural history of bovine urinary bladder tumours, suggesting an important role for E5 in carcinogenesis. Finally, the system provides a suitable animal model of papillomavirus-associated cancer to test therapeutic vaccination against E5. Successful bladder tumour regression would provide a valuable model for therapeutic vaccination against papillomavirus-associated tumours.

Abstract
PURPOSE The purpose of this study was to examine the tumor specificity, cytotoxicity, and granulocyte macrophage colony-stimulating factor expression of CG0070, a conditionally replicating oncolytic adenovirus, in human bladder transitional cell carcinoma (TCC) cell lines and determine its antitumor efficacy in bladder TCC tumor models. EXPERIMENTAL DESIGN Virus yield and cytotoxicity assays were used to determine tumor specificity and virus replication-mediated cytotoxicity of CG0070 in a panel of human bladder TCC cell lines and primary cells in vitro. Two s.c. and one orthotopic bladder TCC xenograft tumor models were used to assess antitumor activity of CG0070. RESULTS In a matched isogenic pair of cell lines with differing retinoblastoma (Rb) pathway status, CG0070 showed selective E1a and granulocyte macrophage colony-stimulating factor (GM-CSF) expression in Rb pathway-defective cells. CG0070 replicated in Rb-defective bladder TCC cell lines as efficiently as wild-type adenovirus but produced 100-fold less virus in normal human cells. CG0070 was up to 1,000-fold more cytotoxic in Rb pathway-defective bladder TCC cells in comparison with normal human cells. Antitumor activity of CG0070 was shown in two bladder TCC s.c. xenograft tumor models following intratumoral injections and intravesical treatment in an orthotopic xenograft tumor model when compared with PBS treatment. CONCLUSIONS In vitro and in vivo studies showed the selective replication, cytotoxicity, GM-CSF production, and antitumor efficacy of CG0070 in several bladder TCC models, suggesting a potential utility of this oncolytic agent for the treatment of bladder cancer. Further studies are warranted to show the role of human GM-CSF in the antitumor efficacy of CG0070.

Abstract
Background To determine the association of human papillomavirus infection (HPV) and transitional cell carcinoma (TCC). Methods Using polymerase chain reaction, fifty-nine bladder tissue specimens of patients with transitional cell carcinoma of bladder compared with 20 bladder samples of cases with non-neoplastic disorders. Results Male to female ratio was similar in the two groups (50/9 vs. 16/4, P = 0.62). Mean age was 67 ± 10.8 years and 52 ± 20.3 years in the case and control groups, respectively (P = 0.6). Of the 59 tissue specimens with diagnosis of transitional cell carcinoma, HPV DNA was detected in 21 (35.6%) samples, while it was present in only one sample (5%) in the control group (P = 0.008). HPV18 was the most common type of virus with the incidence rate of 17/21(81%). Conclusion HPV might play a causative role in transitional cell carcinoma of bladder in our geographic area.
