Aging (Albany NY) 2020; 13:2264-2278. [PMID: 33323547 PMCID: PMC7880329 DOI: 10.18632/aging.202247] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Accepted: 10/05/2020] [Indexed: 12/12/2022]
Abstract
Multiple studies have previously demonstrated that long intergenic non-coding RNAs (lincRNAs) play an important role in the development of bladder cancer. However, little is known regarding the underlying molecular mechanisms of LINC00482 functions in bladder cancer. The current study aimed to elucidate the role of LINC00482 in the progression of bladder cancer. The initial step was to detect the expressions of LINC00482 and MMP15 in bladder cancer cells and tissue. According to the results from the RT-qPCR, LINC00482 and MMP15 were both highly expressed in bladder cancer cells and tissue. The relationship among LINC00482, FOXA1 and MMP15 was studied via dual-luciferase reporter assay. LINC00482 was positively correlated with MMP15. LINC00482 promoted MMP15 expression by recruiting FOXA1. Using the gain- and loss-of-function approaches, silencing of LINC00482 resulted in the downregulation of VEGF and NF-κB protein levels, decreased expression of inflammatory factors, and inhibited angiogenesis. Silencing of LINC00482 also suppressed tumor-associated inflammation and angiogenesis in vivo, which was found to be reversed by the overexpression of MMP15. The present study demonstrated that LINC00482 induced the expression of MMP15 by interacting with FOXA1, thereby contributing to the inflammation and angiogenesis in bladder cancer.

Front Oncol 2020; 10:582532. [PMID: 33244456 PMCID: PMC7683786 DOI: 10.3389/fonc.2020.582532] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Accepted: 10/12/2020] [Indexed: 01/03/2023] Open
Abstract
Objectives To evaluate bladder cancer by integrating multiple imaging features acquired using multimodal 3.0T magnetic resonance imaging (MRI). Methods We prospectively enrolled 163 consecutive patients including 142 men (mean age, 65.2 years) and 21 women (mean age, 65.8 years). We evaluated the efficiency and reliability of the multiple imaging modalities including T2-weighted spectral attenuated inversion recovery (SPAIR) imaging, dynamic contrast-enhanced (DCE) imaging and diffusion-weighted (DW) imaging, and the imaging feature, apparent diffusion coefficient (ADC) in the identification of the T staging and grading. We compared our imaging findings with the results of histological examination using McNemar’s test. We reported the results under the significance of p < 0.05. Approval for the study was obtained from the local institutional review board. Results The sensitivity and specificity using T2 SPAIR plus DW imaging (sensitivity: 85.2%; specificity: 93.2%), DCE plus DW imaging (sensitivity: 92.4%; specificity: 96.8%), and all the three imaging modalities combined, i.e., T2 SPAIR plus DCE plus DW imaging (sensitivity: 92.5%; specificity: 97.4%), were significantly greater than using T2 SPAIR imaging alone (sensitivity: 74.1%; specificity: 72.2%). One hundred six (93.0%) lesions showed a thin, pedicle arch-like shape and thus primarily demonstrated to be in Ta stage; by contrast, a large number of lesions (137 [85.6%]) were sessile and were found to be in T1 stage. The differences in the ADC were significant between low-grade (877.57 ± 24.15) and high-grade (699.54 ± 23.82) lesions (P < .01). Conclusions T2 SPAIR and DCE plus DW imaging provided useful information for evaluating T staging and grading in bladder cancer. Those imaging features to distinguish Ta stage from T1 stage were presented.

Abstract
Background FSIP1 plays a vital role in tumorigenesis and cancer progression. In bladder cancer, FSIP1 overexpression was associated with poor prognosis of bladder urothelial carcinoma. In this study, we investigated whether FSIP1 is essential in the progression of bladder cancer and the mechanism by which it mediates this effect. Methods FSIP1 expression was knocked down in bladder cancer cells using lentiviral-mediated short hairpin RNA (shRNA). FSIP1 expression was detected using Western blotting, immunohistochemistry (IHC), and quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). The effects of FSIP1 knockdown on tumor cells were assessed using colony formation, 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), and flow cytometry (FCM) apoptosis assays in vitro and BALB/c nude mouse xenograft model in vivo. Results The findings suggested that FSIP1 protein was highly expressed in bladder cancer cell lines. Knockdown of FSIP1 resulted in reduced tumor cell viability, cell cycle arrest at G0/G1 phase and apoptosis of bladder cancer cell lines (P<0.05). Moreover, knockdown of FSIP1 expression suppressed the tumor formation and growth of bladder cancer xenografts (P<0.05). At the gene level, knockdown of FSIP1 expression downregulated the activity of the PI3K/AKT signaling pathway. Conclusion This study demonstrated that knockdown of FSIP1 suppressed bladder cancer cell malignant behaviors in vitro and in vivo through the inhibition of the PI3K/AKT signaling pathway, suggesting that targeting FSIP1 could be further evaluated as a potential therapeutic strategy in bladder cancer.

Abstract
Urothelial bladder cancer is a common malignancy requiring a multidisciplinary approach to treatment. Significant recent advances have been made in terms of the genetic and molecular characterization of bladder cancer subtypes, and novel treatment approaches are being investigated and approved. Given the important role of imaging in the diagnosis, staging, and follow-up of this disease, it is necessary for radiologists to remain up-to-date in terms of nomenclature and standards of care. In this review, recent developments in bladder cancer characterization and treatment will be discussed, with reference to the contributions of imaging in non-muscle-invasive, muscle-invasive, and metastatic settings.

Increased Nicotinamide Phosphoribosyltransferase and Cystathionine-β-Synthase in Renal Oncocytomas, Renal Urothelial Carcinoma, and Renal Clear Cell Carcinoma. Anticancer Res 2017; 37:3423-3427.

Abstract
BACKGROUND Renal oncocytomas (ROs), and clear cell (RCC) and urothelial carcinomas (UC), are common renal neoplasms. Nicotinamide phosphoribosyltransferase (Nampt) catalyzes the rate-limiting step of NAD+ synthesis and its expression is increased in several tumors. Nampt concomitantly regulates hydrogen sulfide (H2S)-synthesizing enzyme levels, including cystathionine-β-synthase (CBS). MATERIALS AND METHODS We used tissue microarrays to examine Nampt and the H2S-synthesizing enzyme CBS protein levels in benign kidney, RCC, UC and ROs. RESULTS Compared to benign kidney, all three neoplasms showed increased Nampt and CBS protein levels, with the levels increasing in RCC at higher Fuhrman grades. CONCLUSION H2S is known to ameliorate chronic renal failure but, as yet, no role for H2S in renal neoplasia has been demonstrated. Here, we showed, for the first time, that Nampt, CBS and, likely, H2S likely play a role in malignant and benign neoplastic renal disease.

Overexpression of autotaxin is associated with human renal cell carcinoma and bladder carcinoma and their progression. Med Oncol 2016; 33:131.

Abstract
Autotaxin (ATX) as an important tumor cell motility-stimulating factor is upregulated in many different types of cancer. ATX, a member of the ectonucleotide pyrophosphatase and phosphodiesterase family of enzymes, possesses lysophospholipase D activity which hydrolyzes lysophosphatidylcholine to generate the potent tumor growth factor and mitogen lysophosphatidic acid (LPA). LPA acts on specific G-protein-coupled receptors, thereby regulating cell growth, migration, and survival. This study aimed to investigate the differences in gene expression pattern of ATX between cancerous and adjacent normal tissue of human renal cell carcinoma (RCC) and bladder carcinoma (BC) and find the correlation between ATX expression and clinicopathological features of both of these carcinomas. Both the RCC and BC tissues and with the adjacent normal tissues were collected. Immunohistochemistry and Western blotting analysis were used to detect the extent of ATX expression in all of these samples. Immunohistochemistry and Western blot analysis revealed that expression of ATX protein in carcinoma tissues is significantly higher than that in the adjacent normal tissues. Immunohistochemistry analysis showed that ATX is localized in cytoplasm. Western blotting analysis showed that ATX protein is expressed in both RCC and BC, and the expression levels were 69.5 and 48.0 %, respectively, higher in RCC and BC carcinoma tissue samples than in the adjacent normal tissues, which is consistent with the results of immunohistochemistry study. Thus, this study provided the evidence that ATX is highly expressed in both RCC and BC. Further research can be done to identify the diagnosis and treatment significance of both these carcinomas.

Abstract
Transcription factor AP-2 alpha (AP-2α or TFAP2A) is a newly identified prognostic marker of chemotherapy; its expression is positively correlated with chemosensitivity and survival of cancer patients. Using computational programs, we predicted that the coding region of AP-2α gene contains a potential miRNA response element (MRE) of miR-193a-5p, and the single nucleotide polymorphism (SNP) site (c.497A>G, rs111681798) resides within the predicted MRE. The results of luciferase assays and Western blot analysis demonstrated that miR-193a-5p negatively regulated the expression of AP-2α proteins, but have no influence on the mutant AP-2α (c.497A>G). Infection with lentiviral AP-2α gene or miR-193a-5p inhibitor in the bladder cancer cells decreased migration and cisplatin resistance, while knockdown of AP-2α gene or overexpression of miR-193a-5p in the urothelial cell line SV-HUC-1 increased migration and cisplatin resistances. We concluded that miR-193a-5p induced cisplatin resistance by repressing AP-2α expression in bladder cancer cells.

Abstract
The renal cell carcinomas (RCC), clear cell, papillary, and chromophobe, have recently undergone an unmatched genomic characterization by The Cancer Genome Atlas. This analysis has revealed new insights into each of these malignancies and underscores the unique biology of clear cell, papillary, and chromophobe RCC. Themes that have emerged include distinct mechanisms of metabolic dysregulation and common mutations in chromatin modifier genes. Importantly, the papillary RCC classification encompasses a heterogeneous group of diseases, each with highly distinct genetic and molecular features. In conclusion, this review summarizes RCCs that represent a diverse set of malignancies, each with novel biologic programs that define new paradigms for cancer biology.
