Abstract
Cellular and molecular immune components play a crucial role in the development and perpetuation of human malignancies, shaping anti-tumor responses. A novel immune regulator is interleukin-37 (IL-37), already shown to be involved in the inflammation associated with the pathophysiology of many human disorders, including cancer. The interplay between tumor and immune cells is of great importance, especially for highly immunogenic tumors such as bladder urothelial carcinoma (BLCA). This study aimed to investigate the potential of IL-37 and its receptor SIGIRR (single immunoglobulin IL-1-related receptor) to serve as prognostic and/or diagnostic markers in patients with BLCA. To this end, a series of bioinformatics tools processing -omics datasets and specifically designed qPCR assays on human BLCA tumors and cancer cell lines were utilized. Bioinformatics analysis revealed that IL-37 levels correlate with BLCA tumor development and are higher in patients with longer overall survival. Furthermore, mutations on SIGIRR are associated with enhanced infiltration of the tumor by regulatory T cells and dendritic cells. Based on the qPCR validation experiments, BLCA epithelial cells express the IL-37c and IL-37e isoforms, while the latter is the predominant variant detected in tumor biopsies, also associated with higher grade and the non-muscle-invasive type. This is the first time, to the best of our knowledge, that IL-37 and SIGIRR levels have been assessed in BLCA tumor lesions, and associations with pathological and survival parameters are described, while a transcript variant-specific signature is indicated to have a diagnostic potential. These data strongly indicate the need for further investigation of the involvement of this cytokine and interconnected molecules in the pathophysiology of the disease and its prospective as a therapeutic target and biomarker for BLCA.

Abstract
Specific membrane capacitance (SMC) and Young's modulus are two important parameters characterizing the biophysical properties of a cell. In this work, the SMC and Young's modulus of two cell lines, RT4 and T24, corresponding to well differentiated (low grade) and poorly differentiated (high grade) urothelial cell carcinoma (UCC), respectively, were quantified using microfluidic and AFM measurements. Quantitative differences in SMC and Young's modulus values of the high-grade and low-grade UCC cells are, for the first time, reported.

Abstract
The study of nuclear mechanical properties can provide insights into nuclear dynamics and its role in cellular mechanotransduction. While several methods have been developed to characterize nuclear mechanical properties, direct intracellular probing of the nucleus in situ is challenging. Here, a modified AFM (atomic force microscopy) needle penetration technique is demonstrated to mechanically characterize cell nuclei in situ. Cytoplasmic and nuclear stiffness were determined based on two different segments on the AFM indentation curves and were correlated with simultaneous confocal Z-stack microscopy reconstructions. On the basis of direct intracellular measurement, we show that the isolated nuclei from fibroblast-like cells exhibited significantly lower Young's moduli than intact nuclei in situ. We also show that there is in situ nucleus softening in the highly metastatic bladder cancer cell line T24 when compared to its less metastatic counterpart RT4. This technique has potential to become a reliable quantitative measurement tool for intracellular mechanics studies.

Abstract
Established human cell lines derived from a transitional cell carcinoma (J82), a squamous carcinoma (SCaBER), and a normal urothelium (HCV-29) were used to assess the relative cytotoxicity and tissue specificity of putative virulence determinants of P. gingivalis W83. Intact cells of W83 had no effect on any of the cell lines, whereas disrupted cells caused extensive cytotoxicity particularly to monolayers of HCV-29 and J82. The purified cysteine proteinase, gingivain, caused marked disruption of the basement membrane of the SCaBER monolayers but had no cytotoxic effects. Use of the thiol-inhibitor, 2,2'-dipyridyl disulphide revealed that the effects observed with the vesicles and the culture supernatant were due to the presence of the cysteine proteinase. The attachment of vesicles to the SCaBER cells was evident in electron micrographs. Short-chain volatile fatty acids added in concentrations equivalent to those present in the culture supernatant had no effect on any of the cell lines tested. Culture supernatants obtained from high speed centrifugation (150,000 x g) showed no cytotoxic effects. This was in marked contrast to the supernatant obtained by lower sedimentation (18,000 x g), which damaged all monolayers tested. These results suggest that these cell lines are potentially useful for assessing putative virulence determinants of P. gingivalis and other periodontal pathogens.

Abstract
Mice were immunized with cultured cells derived from transitional cell carcinoma of the human urinary bladder (TCC). Spleen cells were fused with mouse myeloma cell line Sp2/0-Ag14 and the hybridomas obtained screened for antibody production against a panel of human cells. Two hybridomas were selected for further studies. The antibodies from one of these hybridomas (P7A5-4) could clearly discriminate between malignant and normal cells from the bladder, both when tested with cultured cells and fresh tissue. The P7A5-4 antibodies, however, also reacted with some non-TCC cultured carcinoma and melanoma cells but to a lesser extent. This difference in reactivity was even more pronounced in the fresh tumours tested, thus indicating a quantitative difference in antigen expression between TCC and other cells. From extracts of TCC cells, P7A5-4 bound three polypeptides of mol. wts 92Kd (ConA+), 23 and 17Kd (ConA-). The antibody derived from hybridoma SK4H-12 bound a ConA reactive glycopeptide of 100Kd mol. wt, the expression of which was almost entirely restricted to urothelial cell lines and tissue of TCC origin, as shown by immunocytochemical studies. The finding in this study of new antigens associated with urinary bladder carcinoma, extend the results obtained previously in our laboratory (Koho et al., 1984; Paulie et al., 1984) and further delineate the heterogeneity of tumour-associated antigens in this human tumour system.

Abstract
Spleen cells from BALB/c mice immunized with cells derived from transitional cell carcinomas (TCC) of the human urinary bladder were fused with mouse myeloma Sp 2/0 Ag14 cells. Monoclonal antibodies from six established hybridomas were investigated for specificity in a cell ELISA and in indirect immunofluorescence against a large panel of fixed intact cells. Three of the antibodies reacted with half or more of the eight bladder tumors and with a few unrelated tumors. They did not react at all with malignant or normal cells of hematopoietic origin. A fourth antibody reacted with seven of eight bladder tumors. It also reacted weakly with a prostatic carcinoma, with five of six malignant or transformed B cell lines, and with a subpopulation of normal lymphocytes, but not with any of the other cells on the test panel. These four antibodies did not react with cells derived from normal urothelium. The results suggest that these antibodies might recognize cell-type-restricted antigens associated with malignancy. Another antibody reacted with almost all urothelium-derived cells. It also reacted with three of three melanomas but not with any other cells on the panel. The sixth antibody reacted with 32 of the 37 cells tested. The spectrum of reactivities displayed by the antibody suggested that it recognizes HLA antigens.

Abstract
The Con A acceptor glycoproteins of murine and human tumour cell lines revealed by two-dimensional fingerprinting on polyacrylamide gels fall into two main categories: constant glycoproteins expressed by all cell lines and variable glycoproteins which are only expressed by particular tumour cell lines. Since the number of variable glycoproteins on a typical fingerprint is 50, fingerprints from different cell lines are readily distinguishable. However the variable glycoproteins are not expressed idiosyncratically and cell lines derived from similar classes of tumours express similar patterns of the variable glycoproteins. For example, murine fibrosarcomas express patterns which are virtually identical with one another. Characteristic patterns are also expressed by murine macrophage tumour lines, human carcinomas and human B lymphoblastoid cells. Thus, the variable glycoproteins behave as a set of linked markers which are indicators of the type of normal pre-neoplastic precursor cell from which a tumour is derived and appear to be a new type of marker for tumour cell classification. Antibodies to these glycoproteins could prove useful in tumour localisation and diagnosis.

Abstract
Antibody-dependent cell-mediated cytotoxicity was used to detect HLA antigens on tissue cultured lymphoblastoid cells (phytohemagglutin blasts and Epstein-Barr virus lines) and transitional cell carcinomas. The results agreed with those obtained on fresh peripheral blood lymphocytes by conventional HLA typing. The same HLA antigens were detected on cells from an individual irrespective of their tissue origin or length of time in vitro. Antibody-dependent cell-mediated cytotoxicity (ADCC) showed that HLA-Cw5 and HLA-Cw8 were cross-reactive. An HLA-Cw5 antiserum that was negative for HLA-Cw8 positive cells in complement-mediated lymphocytotoxicity reacted strongly with HLA-Cw8 donor cells in ADCC. Similarly HLA-Cw8 antibodies were detected in HLA-B14 antisera, which reacted on all HLA-Cw5-positive donor cells. Absorption of sera with HLA-Cw5-positive lymphoid cells removed HLA-Cw5 and HLA-Cw8 specificities but spared HLA-B14. Absorption of HLA-B14 antisera with HLA-B14/Cw8-positive cells removed HLA-Cw5, HLA-Cw8, and HLA-B14 reactivities. Sequential immune precipitation and gel electrophoresis confirmed that HLA-Cw5 and HLA-Cw8 were cross-reactive and that HLA-B14 was physically separable from HLA-Cw8.

Abstract
Recent reports on transfection of mouse cells with DNA from the established human urinary bladder cancer cell lines T24, J82 and EJ (MGH-U1), and the presence of an identical genetic modification in T24 and EJ cells have led us to examine the identity of these and other cultures of urothelial origin. By the criteria of HLA-A-B-C typing 7 and isozyme analysis, we conclude that EJ (MGH-U1) and some cultures of J82 are in fact T24 cells. However, five other bladder cancer cell lines, J82 (CO'T), RT4, RT112, TCCSuP and SCaBER, are clearly distinct from T24 by HLA typing (ref. 7) and/or isozyme patterns.
