Abstract
There is now increasing recognition of the important role of androgen receptor (AR) in modulating immune function. To gain a comprehensive understanding of the effects of AR activity on cancer immunity, we employed a computational approach to profile AR activity in 33 human tumor types using RNA-Seq datasets from The Cancer Genome Atlas. Our pan-cancer analysis revealed that the genes most negatively correlated with AR activity across cancers are involved in active immune system processes. Importantly, we observed a significant negative correlation between AR activity and IFNγ pathway activity at the pan-cancer level. Indeed, using a matched biopsy dataset from subjects with prostate cancer before and after AR-targeted treatment, we verified that inhibiting AR enriches immune cell abundances and is associated with higher IFNγ pathway activity. Furthermore, by analyzing immunotherapy datasets in multiple cancers, our results demonstrate that low AR activity was significantly associated with a favorable response to immunotherapy. Together, our data provide a comprehensive assessment of the relationship between AR signaling and tumor immunity.

Frequency of Androgen Receptor Positivity in Tumors: A Study Evaluating More Than 18,000 Tumors. Biomedicines 2024; 12:957. [PMID: 38790919 PMCID: PMC11117763 DOI: 10.3390/biomedicines12050957] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 04/19/2024] [Accepted: 04/22/2024] [Indexed: 05/26/2024] Open
Abstract
Androgen receptor (AR) is a transcription factor expressed in various normal tissues and is a therapeutic target for prostate and possibly other cancers. A TMA containing 18,234 samples from 141 different tumor types/subtypes and 608 samples of 76 different normal tissue types was analyzed by immunohistochemistry. AR positivity was found in 116 tumor types including 66 tumor types (46.8%) with ≥1 strongly positive tumor. Moderate/strong AR positivity was detected in testicular sex cord-stromal tumors (93.3-100%) and neoplasms of the prostate (79.3-98.7%), breast (25.0-75.5%), other gynecological tumors (0.9-100%), kidney (5.0-44.1%), and urinary bladder (5.4-24.2%). Low AR staining was associated with advanced tumor stage (pTa versus pT2-4; p < 0.0001) in urothelial carcinoma; advanced pT (p < 0.0001), high tumor grade (p < 0.0001), nodal metastasis (p < 0.0001), and reduced survival (p = 0.0024) in invasive breast carcinoma; high pT (p < 0.0001) and grade (p < 0.0001) in clear cell renal cell carcinoma (RCC); and high pT (p = 0.0055) as well as high grade (p < 0.05) in papillary RCC. AR staining was unrelated to histopathological/clinical features in 157 endometrial carcinomas and in 221 ovarian carcinomas. Our data suggest a limited role of AR immunohistochemistry for tumor distinction and a prognostic role in breast and clear cell RCC and highlight tumor entities that might benefit from AR-targeted therapy.

Abstract
Preclinical and clinical data suggest that androgen receptor signaling strongly contributes to bladder cancer development. The roles of the androgen receptor in bladder carcinogenesis have obvious implications for understanding the strong male sex bias in this disease and for potential therapeutic strategies as well. In this review, we summarize what is known about androgen receptor signaling in urothelial carcinoma as well as in tumor-infiltrating immune cells, reviewing preclinical and clinical data. We also highlight clinical trial efforts in this area.

Abstract
Bladder cancer is the ninth most common cancer worldwide with a striking sex-based difference in incidence. Emerging evidence indicates that the androgen receptor (AR) might promote the development, progression and recurrence of bladder cancer, contributing to the observed sex differences. Targeting androgen-AR signalling has promise as potential therapy for bladder cancer and helps to suppress progression of this disease. In addition, the identification of a new membrane AR and AR-regulated non-coding RNAs has important implications for bladder cancer treatment. The success of human clinical trials of targeted-AR therapies will help in the development of improved treatments for patients with bladder cancer.

Abstract
Stress-responsive microRNAs (miRNAs) contribute to the regulation of cellular homeostasis or pathological processes, including carcinogenesis, by reprogramming target gene expression following human exposure to environmental or dietary xenobiotics. Herein, we predicted the targets of carcinogenic mycotoxin-responsive miRNAs and analyzed their association with disease and functionality. miRNA target-derived prediction indicated potent associations of oncogenic mycotoxin exposure with metabolism- or hormone-related diseases, including sex hormone-linked cancers. Mechanistically, the signaling network evaluation suggested androgen receptor (AR)-linked signaling as a common pivotal cluster associated with metabolism- or hormone-related tumorigenesis in response to aflatoxin B1 and ochratoxin A co-exposure. Particularly, high levels of AR and AR-linked genes for the retinol and xenobiotic metabolic enzymes were positively associated with attenuated disease biomarkers and good prognosis in patients with liver or kidney cancers. Moreover, AR-linked signaling was protective against OTA-induced genetic insults in human hepatocytes whereas it was positively involved in AFB1-induced genotoxic actions. Collectively, miRNA target network-based predictions provide novel clinical insights into the progression or intervention against malignant adverse outcomes of human exposure to environmental oncogenic insults.

Abstract
The current research was constructed to throw the light on the protective possibility of Chlorella vulgaris (C. vulgaris) and Spirulina platensis (S. platensis) against lead acetate-promoted testicular dysfunction in male rats. Forty rats were classified into four groups: (i) control, (ii) rats received lead acetate (30 mg/kg bw), (iii) rats concomitantly received lead acetate and C. vulgaris (300 mg/kg bw), (vi) rats were simultaneously treated with lead acetate and S. platensis (300 mg/kg bw) via oral gavage for 8 weeks. Lead acetate promoted testicular injury as expressed with fall in reproductive organ weights and gonadosomatic index (GSI). Lead acetate disrupted spermatogenesis as indicated by sperm cell count reduction and increased sperm malformation percentage. Lead acetate-deteriorated steroidogenesis is evoked by minimized serum testosterone along with maximized follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels. Testicular oxidative, inflammatory, and apoptotic cascades are revealed by elevated acid phosphatase (ACP) and sorbitol dehydrogenase (SDH) serum leakage, declined testicular total antioxidative capacity (TAC) with elevated total oxidative capacity (TOC), tumor necrosis factor alpha (TNF-α), caspase-3 levels, lessened androgen receptor (AR) expression, and histopathological lesions against control. Our research highlights that C. vulgaris or S. platensis therapy can modulate lead acetate-promoted testicular dysfunction via their antioxidant activity as expressed by elevated TAC and reduced TOC, immunomodulatory effect as indicated by lessened TNF-α level, and anti-apoptotic potential that was revealed by minimized caspase-3 levels. As well as restoration of testicular histoarchitecture, androgen receptor, steroidogenesis, and spermatogenesis were detected with better impacts to S. platensis comparing with C. vulgaris. Therefore, further clinical trials are needed to test S. platensis and C. vulgaris as a promising candidate in treating male infertility.

High Androgen Receptor mRNA Expression Is Associated with Improved Outcome in Patients with High-Risk Non-Muscle-Invasive Bladder Cancer. Life (Basel) 2021; 11:life11070642. [PMID: 34209360 PMCID: PMC8306811 DOI: 10.3390/life11070642] [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: 06/08/2021] [Revised: 06/24/2021] [Accepted: 06/28/2021] [Indexed: 12/21/2022] Open
Abstract
The role of the androgen receptor (AR) in non-muscle-invasive bladder cancer (NMIBC) remains controversial. We retrospectively analyzed the mRNA expression of AR using RT-qPCR in 95 patients with high-risk NMIBC treated with a bladder-sparing approach and correlated AR with clinical data and recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS). The mRNA expression of AR and KRT5, i.e., the basal-like subtype, was strongly correlated (rs = 0.456; p < 0.001). AR (p = 0.053) and KRT5 (p = 0.029) mRNA expression was negatively correlated with tumor grade. Kaplan–Meier analyses indicated significantly prolonged CSS (p = 0.020) and OS (p = 0.015) and a trend towards longer RFS (p = 0.051) in patients with high AR expression. High KRT5 expression was associated with significantly longer RFS (p = 0.033), CSS (p = 0.029) and OS (p = 0.030), while high KRT20 expression was associated with reduced RFS (p = 0.042). In multivariable analysis, none of the molecular markers was an independent prognostic factor. When performing a substratification with regard to molecular markers and clinicopathological parameters, high AR expression showed improved OS in patients with high KRT20 mRNA expression (p = 0.041). Women showed significantly longer OS in cases with high AR expression (p = 0.011). High AR was associated with significantly improved CSS in males (p = 0.044) and patients with instillation therapy (p = 0.040), while OS was improved regardless of instillation therapy. Younger patients with high AR expression had significantly improved RFS (p = 0.021), CSS (p = 0.014) and OS (p = 0.007). RFS was also improved in patients with high AR and low expression of either KRT5 (p = 0.003) or KRT20 (p = 0.014), but not in patients with high expression of KRT5 or KRT20. In conclusion, high AR mRNA expression is correlated with KRT5 mRNA expression and is associated with an improved outcome in high-risk NMIBC.

Metastatic colon cancer of the small intestine diagnosed using genetic analysis: a case report. Diagn Pathol 2020; 15:106. [PMID: 32867793 PMCID: PMC7457373 DOI: 10.1186/s13000-020-01019-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Accepted: 08/21/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Intestinal-type adenocarcinoma is widely detected in the gastrointestinal tract, head and neck, lower respiratory and urinary systems. Determining the nature (monoclonal or multicentric) of the intestinal adenocarcinoma is sometimes a diagnostic challenge owing to its occurrence at various locations of the body, especially in the lower gastrointestinal tract. Herein, we successfully diagnosed metastatic colon cancer in the small intestine using tumor protein 53 gene (TP53) mutation analysis. CASE PRESENTATION An 83-year-old woman presented with severe abdominal pain and nausea at the emergency department of the hospital. Her history included surgery and adjuvant chemotherapy for colon and breast cancers. Abdominal computed tomography revealed small intestinal dilation, which was associated with the mural nodule detected on fluorodeoxyglucose positron emission tomography. Laparoscopy-assisted small bowel resection was performed based on the diagnosis of small bowel obstruction, probably due to recurrence of the colon or breast cancer. Macroscopically, an ulcerated tumor was present in the resected small intestine. Histologically, the cancer cells showed infiltrative growth of colonic dysplastic glands, whose non-specific finding made it difficult to determine the relationship with past colon cancers. Retrospective pathological examination confirmed that the previous breast and colon carcinomas were primary cancers. Immunohistochemical analysis revealed that the small intestinal and colon cancer cells showed diffuse positive tumor protein 53 (p53) expression. However, the breast cancer cells showed only weakly positive p53 expression. In addition, TP53 mutational analysis detected an identical missense mutation (p.T211I) between the two intestinal cancers. Moreover, further molecular genetic work-up revealed that both small intestinal and colon adenocarcinomas harbored an identical missense mutation (p.G12D) of KRAS gene. In conclusion, the small intestinal cancer in this case was identified as a metastatic adenocarcinoma arising from a past colon cancer. CONCLUSIONS Genetic analyses help in clarifying the identity of the cells in multiple cancer cases. In morphologically indeterminate cases, molecular analysis of common cancer-related genes can be useful for a precise and reproducible diagnosis.

Abstract
The von Hippel–Lindau protein (pVHL) is a tumour suppressor mainly known for its role as master regulator of hypoxia-inducible factor (HIF) activity. Functional inactivation of pVHL is causative of the von Hippel–Lindau disease, an inherited predisposition to develop different cancers. Due to its impact on human health, pVHL has been widely studied in the last few decades. However, investigations mostly focus on its role in degrading HIFs, whereas alternative pVHL protein–protein interactions and functions are insistently surfacing in the literature. In this review, we analyse these almost neglected functions by dissecting specific conditions in which pVHL is proposed to have differential roles in promoting cancer. We reviewed its role in regulating phosphorylation as a number of works suggest pVHL to act as an inhibitor by either degrading or promoting downregulation of specific kinases. Further, we summarize hypoxia-dependent and -independent pVHL interactions with multiple protein partners and discuss their implications in tumorigenesis.

Abstract
Immunohistochemistry represents an indispensable complement to an epidemiology and morphology-driven approach to tumor diagnosis and site of origin assignment. This review reflects the state of my current practice, based on 15-years' experience in Pathology and a deep-dive into the literature, always striving to be better equipped to answer the age old questions, "What is it, and where is it from?" The tables and figures in this manuscript are the ones I "pull up on the computer" when I am teaching at the microscope and turn to myself when I am (frequently) stuck. This field is so exciting because I firmly believe that, through the application of next-generation immunohistochemistry, we can provide better answers than ever before. Specific topics covered in this review include (1) broad tumor classification and associated screening markers; (2) the role of cancer epidemiology in determining pretest probability; (3) broad-spectrum epithelial markers; (4) noncanonical expression of broad tumor class screening markers; (5) a morphologic pattern-based approach to poorly to undifferentiated malignant neoplasms; (6) a morphologic and immunohistochemical approach to define 4 main carcinoma types; (7) CK7/CK20 coordinate expression; (8) added value of semiquantitative immunohistochemical stain assessment; algorithmic immunohistochemical approaches to (9) "garden variety" adenocarcinomas presenting in the liver, (10) large polygonal cell adenocarcinomas, (11) the distinction of primary surface ovarian epithelial tumors with mucinous features from metastasis, (12) tumors presenting at alternative anatomic sites, (13) squamous cell carcinoma versus urothelial carcinoma, and neuroendocrine neoplasms, including (14) the distinction of pheochromocytoma/paraganglioma from well-differentiated neuroendocrine tumor, site of origin assignment in (15) well-differentiated neuroendocrine tumor and (16) poorly differentiated neuroendocrine carcinoma, and (17) the distinction of well-differentiated neuroendocrine tumor G3 from poorly differentiated neuroendocrine carcinoma; it concludes with (18) a discussion of diagnostic considerations in the broad-spectrum keratin/CD45/S-100-"triple-negative" neoplasm.

Abstract
BACKGROUND About 75% of urothelial bladder cancers are non-muscle invasive (NMIBC), and limited to mucosa (Ta or CIS) or sub-mucosa (T1). An increase of androgen expression and androgen receptors has a positive effect on oncogenic expression. We aimed to evaluate whether 5-alpha reductase inhibitors (5-ARI) have a role in NMIBC. METHODS We retrospectively evaluated the clinical and pathological data of 423 patients with NMIBC who underwent transurethral bladder resection. We considered the number of resections, number of total recurrences, time of recurrences, and histopathology details. The population was classified into two groups: treated and untreated with 5-ARIs. The enrolled patients were in treatment with 5ARIs for symptomatic prostatic hyperplasia for at least 12 months. Mean follow-up time was 30.43 months. RESULTS Patients treated with 5-ARIs had a lower rate of recurrence (14%) than the untreated group (37%). There was a significant difference in the mean number of recurrences between the untreated and the treated group (P=0.006). Furthermore, the treated group showed a significantly greater number of low than high grade tumors, compared to the untreated group (P≤0.05). There was a significant decrease in the number of muscle invasive tumors in treated patients (P=0.032). The recurrence-free survival rate of patients treated with 5-ARIs was significantly higher (P=0.0001). CONCLUSIONS Long-term treatment with 5-ARIs might reduce the risk of bladder tumor recurrence, extension of lesions and increase the recurrence-free survival rate. A long-term, randomized prospective study could definitively assess the possible role of these drugs.

Abstract
In order to evaluate the potential prognostic/predictive role of androgen receptor (AR) expression in non-muscle-invasive bladder cancer (NMIBC), and whether it may represent a therapeutic target, we conducted a systematic search of the literature using 'androgen receptor or AR', 'testosterone', 'bladder cancer' and 'non-muscle invasive bladder cancer or NMIBC' as keywords. Eleven studies met the inclusion/exclusion criteria. No significant association was found between AR status and patients' gender (p=0.232), tumor size (p=0.975), tumor stage (p=0.237), tumor grade (p=0.444), tumor multicentricity (p=0.397), concomitant CIS (p=0.316) and progression of disease (p=0.397). On the other hand, relative lack of AR expression was significantly correlated to recurrent disease (p=0.001). Evidence for a direct correlation between AR expression and recurrence-free survival of patients with NMIBC indicate ARs as potential markers of BC behavior; moreover, the finding of a role of androgen blockade therapy in improving survival highlights the potential clinical application of this pathway, which deserves to be further explored.

Pathol Oncol Res 2019; 26:605-614.

Abstract
The relationship between androgen receptor expression and renal cell carcinoma risk remains controversial. This study is aimed to investigate the clinical significance of androgen receptor expression in renal cell carcinoma. A computerized bibliographic search of Embase, the PubMed, and Web of Science combined with manual research between 1977 and 2017 was conducted to explore the association between androgen receptor expression and clinicopathological features of renal cell carcinoma. Data were analyzed by a meta-analysis using RevMan 5.3 analysis software. Eleven retrospective studies with 1839 renal cell carcinoma cases were finally included according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. It was found that there was no significant difference between androgen receptor expression and susceptibility, pathological type, metastatic status, metastatic type (lymph or distant metastasis) and cancer-specific survival of renal cell carcinoma (P > 0.05). However, positive androgen receptor expression was demonstrated to be significantly associated with male patients, lower pathological grade, and earlier tumor stage of renal cell carcinoma (OR = 1.69, 95% CI = 1.30-2.19, P < 0.0001; OR = 2.06, 95% CI = 1.49-2.85, P < 0.0001; OR = 2.81, 95% CI = 1.30-6.12, P = 0.009; respectively). In conclusion, higher androgen receptor expression was correlated with male patients, low tumor grade and early stage of renal cell carcinoma. Based on current results, androgen receptor-inhibited target therapy for renal cell carcinoma patients may be of limited benefits and should be taken into more evaluations.

Abstract
We report a case with prostate cancer and gastric neuroendocrine carcinoma. A 72-year old male presented with a gastric lesion 5 months after radical prostatectomy. The lesion was immunohistochemically positive for PSA, alpha-methylacyl-CoA racemase, synaptophysin, and chromogranin A, but negative for androgen receptor (AR). Differentiating gastric neuroendocrine carcinoma from gastric metastasis of prostate cancer is difficult, as both lesions exhibit similar acinar cell proliferation with prominent nucleoli.1 We discuss the diagnostic process of this case and how AR was a useful specific marker for diagnosing primary gastric neuroendocrine carcinoma.

Abstract
Men have had a substantially higher risk of developing bladder cancer than women. This has prompted research on androgen-mediated androgen receptor (AR) signaling in urothelial cancer. Indeed, increasing preclinical evidence indicates that AR activation correlates with the promotion of urothelial carcinogenesis and tumor outgrowth. In this article, we summarize and discuss available data suggesting the involvement of androgens and the AR pathway in the development and progression of urothelial cancer. Although precise mechanisms for the functions of AR and related signals in urothelial cells remain far from being fully understood, current observations may offer effective chemopreventive and therapeutic approaches for urothelial cancer. Clinical application of various anti-AR therapies available for AR-dependent prostate cancer to urothelial cancer patients is thus anticipated.

Abstract
AIMS Bladder urothelial carcinoma is increasing in incidence with age and its prognosis could become worse when accompanied with metastasis. Effective treatment of these advanced patients is required and it becomes important to understand its underlying biology of this neoplasm, especially with regard to its biological pathways. A potential proposed pathway is androgen receptor (AR)-mediated intracellular signaling but the details have remained relatively unexplored. MAIN METHODS The expression of AR, 5α-reductase type1 (5αR1) and 5α-reductase type2 (5αR2) were examined in the bladder cancer cell line T24 and surgical pathology specimens. We also evaluated the status of androgen related cell proliferation and migration using the potent, non-aromatizable androgen agonist 5α-dihydrotestosterone (DHT). KEY FINDINGS DHT treatment significantly increased AR mRNA expression level, but not those of 5αR1 and 5αR2 in T24 cells. DHT also suppressed cellular migration with weaker and opposite effects on cell proliferation. A significant inverse correlation was detected between pT stage and AR, 5αR1 and 5αR2 immunoreactivity. SIGNIFICANCE Inverse correlations detected between tumor grade and AR/androgen metabolizing enzyme also suggested that the loss of AR and androgen-producing enzymes could be associated with tumor progression. Effects of DHT on cells also suggest that androgens may regulate cellular behavior.

Abstract
Emerging evidence has demonstrated that androgen receptor (AR) is a promising therapeutic target for bladder cancer. However, the relationship between AR expression and its clinical significance remains controversial. The present in-depth meta-analysis aimed to investigate the correlation between AR expression and clinicopathological features, as well as prognostic value in bladder cancer. A systematic search was performed from PubMed, Web of Knowledge, Embase and the Cochrane Central Search Library by January 2017. The correlation between AR expression and tumor stage, tumor grade, recurrence free survival and progression free survival for patients with bladder cancer was evaluated. A total of 12 relevant studies with 1,652 patient samples were included. AR expression positively correlated with low tumor grade [odds ratio (OR), 1.95; 95% confidence interval (CI), 1.36-2.81], low tumor stage (OR, 2.06; 95% CI, 1.02-4.16) and low recurrence rate [hazard ratio (HR), 0.48; 95% CI, 0.31-0.75] in Caucasian patients. While, its expression had no significant impact on cancer susceptibility (OR, 1.62; 95% CI, 0.19-13.72; P=0.44) and progression-free survival (HR, 1.20; 95% CI, 0.86-1.66; P=0.77). The present meta-analysis indicated that AR expression correlates with tumor grade, clinical stage and recurrence rates in the specified population and classification system. Further studies are required to determine the precise role of AR in bladder cancer.

Abstract
Objective Emerging preclinical evidence suggests the involvement of sex hormones and their receptor signals in the development and progression of bladder cancer. Meanwhile, previous studies have demonstrated conflicting results on the relationship between the status of sex hormone receptors in urothelial tumors and histopathological characteristics of the tumors or patient outcomes. We therefore conducted this meta-analysis to assess the clinicopathological impact of the expression of androgen receptor (AR) and estrogen receptors (ERs) in bladder cancer. Methods A comprehensive literature search in databases (i.e. PubMed, Web of Science, Cochrane) was performed for all immunohistochemical studies stained for AR, ERα, and/or ERβ in surgically resected bladder cancer specimens and analyzed for patient outcomes. We selected eligible studies in accordance with the PRISMA guidelines and analyzed data using R software. Results A total of 2,049 patients from 13 retrospective studies were included in this meta-analysis. The difference in ERα expression between non-tumors and tumors was significant [odds ratio (OR) = 0.412; P<0.001], while those of AR (OR = 3.256; P = 0.336) or ERβ (OR = 0.580; P = 0.674) were not statistically significant. AR positivity in tumors was strongly correlated with gender (male vs. female: OR = 0.658; P = 0.027) or tumor grade (low-grade vs. high-grade: OR = 0.575; P<0.001). ERβ positive rates were significantly higher in high-grade (OR = 2.169; P<0.001) and muscle-invasive (OR = 3.104; P<0.001) tumors than in low-grade and non-muscle-invasive tumors, respectively. Survival analysis in patients with non-muscle-invasive bladder cancer revealed associations between AR expression and better recurrence-free survival [hazard ration (HR) = 0.593; P = 0.006) as well as between ERβ expression and worse recurrence-free (HR = 1.573; P = 0.013) or progression-free (HR = 4.148; P = 0.089) survivals. Conclusions These data suggest down-regulation of ERα expression in bladder tumors, compared with non-neoplastic urothelial tissues. AR or ERβ expression was down- or up-regulated, respectively, in high-grade and/or muscle-invasive bladder cancers. Moreover, immunohistochemistry of AR/ERβ in surgical specimens may serve as prognosticators in patients with non-muscle-invasive bladder tumor.

Kawahara T, Inoue S, Fujita K, Mizushima T, Ide H, Yamaguchi S, Fushimi H, Nonomura N, Miyamoto H. NFATc1 Expression as a Prognosticator in Urothelial Carcinoma of the Upper Urinary Tract. Transl Oncol 2017; 10:318-323. [PMID: 28327458 PMCID: PMC5358926 DOI: 10.1016/j.tranon.2017.01.012] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2017] [Revised: 01/30/2017] [Accepted: 01/31/2017] [Indexed: 11/30/2022] Open
Abstract
We recently found that NFATc1, a member of the NFAT family and a key regulator of the immune response, could induce bladder carcinogenesis and cancer progression. In this study, we immunohistochemically stained for NFATc1 in upper urinary tract urothelial carcinoma (UUTUC) specimens and paired nonneoplastic urothelial tissues. NFATc1 was positive in 51 [52%; 40 (40%) weak (1+), 9 (9%) moderate (2+), and 2 (2%) strong (3+)] of 99 UUTUCs, which was significantly higher than in benign urothelium [30 (36%) of 83; 28 (34%) weak and 2 (2%) moderate] (0 vs 1+/2+/3+, P=.038; 0/1+ vs 2+/3+, P=.023). There were no significant associations between NFATc1 expression pattern and tumor grade or pT stage. However, the positive rates of NFATc1 expression tended to be higher in renal pelvic tumors (60%) than in ureteral tumors (42%; P=.080) as well as in pN+ tumors (75%) than in pN0 tumors (49%; P=.089). Kaplan-Meier and log-rank tests revealed that moderate (2+) to strong (3+) NFATc1 expression correlated with lower progression-free survival (P=.032) and cancer-specific survival (P=.005) rates in the 99 cases. Patients with high (2+/3+) NFATc1 muscle-invasive tumor (n=9) also had a significantly higher risk of cancer-specific mortality (P=.021) compared to those with low (0/1+) NFATc1 muscle-invasive tumor (n=53). Thus, compared with nonneoplastic urothelium, a significant increase in the expression of NFATc1 in UUTUC was seen, implying the involvement of NFATc1 signals in the development of UUTUC. The current results further suggest that NFATc1 overexpression serves as a predictor of poor prognosis in patients with UUTUC.

Abstract
BACKGROUND Renal cell carcinoma (RCC) is one of the most lethal genitourinary cancers. The presence of androgen receptor (AR) in RCC has recently been shown to be associated with higher tumour stage irrespective of gender. Because the clinical context of androgens in female RCC patients is similar to that of prostate cancer patients undergoing androgen-deprivation therapy, mechanisms underlying the emergence of castration-resistant prostate cancer (CRPC) may be at play in AR-positive RCC cells. Therefore, we hypothesized that AR-positive RCC has intratumoral steroidogenesis and that anti-androgen therapy may result in tumour suppression. METHODS Mice were injected with an AR-positive RCC cell line. When tumours became palpable, surgical castration was performed and tumour volume was measured. Using ELISA, the levels of intracellular testosterone and dihydrotesterone were measured in AR-positive human RCC cell lines. Lastly, male mice containing xenografts were treated with enzalutamide or abiraterone acetate (AA) for 3 weeks to measure tumour volume. RESULTS We first observed in vivo that castration retards the growth of AR-positive RCC tumour xenograft in mice. Next, AR-positive human RCC cell lines and tissues were found to have elevated levels of testosterone and dihydrotestosterone and express key enzymes required for intracellular androgen biosynthesis. A mouse xenograft study with AR-positive RCC cell line using the commonly used anti-androgen therapies showed significant tumour suppression (P<0.01). CONCLUSIONS Intracrine androgen biosynthesis is a potential source of androgen in AR-positive RCC and that the androgen signaling axis is a potential target of intervention in RCC.

Abstract
Emerging preclinical findings have indicated that steroid hormone receptor signaling plays an important role in bladder cancer outgrowth. In particular, androgen-mediated androgen receptor signals have been shown to correlate with the promotion of tumor development and progression, which may clearly explain some sex-specific differences in bladder cancer. This review summarizes and discusses the available data, suggesting the involvement of androgens and/or the androgen receptor pathways in urothelial carcinogenesis as well as tumor growth. While the precise mechanisms of the functions of the androgen receptor in urothelial cells remain far from being fully understood, current evidence may offer chemopreventive or therapeutic options, using androgen deprivation therapy, in patients with bladder cancer.

Abstract
INTRODUCTION Patients with non-muscle-invasive or muscle-invasive bladder cancer undergoing surgery and currently available conventional therapy remain having a high risk of tumor recurrence or progression, respectively. Novel targeted molecular therapy is therefore expected to improve patient outcomes. Meanwhile, substantially higher incidence of bladder cancer in men has prompted research on androgen-mediated androgen receptor (AR) signaling in this malignancy. Indeed, preclinical evidence has suggested that AR signaling plays an important role in urothelial carcinogenesis and tumor outgrowth as well as resistance to some of the currently available conventional non-surgical therapies. Areas covered: We summarize and discuss available data suggesting the involvement of AR and its potential downstream targets in the development and progression of bladder cancer. Associations between AR signaling and sensitivity to cisplatin/doxorubicin or bacillus Calmette-Guérin treatment are also reviewed. Expert opinion: AR activation is likely to correlate with the promotion of urothelial carcinogenesis and cancer outgrowth as well as resistance to conventional therapies. Molecular therapy targeting the AR may thus provide effective chemopreventive and therapeutic approaches for urothelial cancer. Accordingly, bladder cancer can now be considered as an endocrine-related neoplasm. Clinical application of various anti-AR therapies available for AR-dependent prostate cancer to bladder cancer patients is anticipated.

Abstract
Increasing evidence has demonstrated that the androgen receptor (AR) plays important roles to promote the metastasis of clear cell renal cell carcinoma (ccRCC). The detailed mechanisms, especially how AR functions via altering the circular RNAs (circRNAs) remain unclear. Here we identified a new circRNA (named as circHIAT1) whose expression was lower in ccRCCs than adjacent normal tissues. Targeting AR could suppress ccRCC cell progression via increasing circHIAT1 expression. ChIP assay and luciferase assay demonstrated that AR suppressed circHIAT1 expression via regulating its host gene, Hippocampus Abundant Transcript 1 (HIAT1) expression at the transcriptional level. The consequences of AR-suppressed circHIAT1 resulted in deregulating miR-195-5p/29a-3p/29c-3p expressions, which increased CDC42 expression to enhance ccRCC cell migration and invasion. Increasing this newly identified signal via circHIAT1 suppressed AR-enhanced ccRCC cell migration and invasion. Together, these results suggested that circHIAT1 functioned as a metastatic inhibitor to suppress AR-enhanced ccRCC cell migration and invasion. Targeting this newly identified AR-circHIAT1-mediated miR-195-5p/29a-3p/29c-3p/CDC42 signals may help us develop potential new therapies to better suppress ccRCC metastasis.

Abstract
In the 1940s Charles Huggins reported remarkable palliative benefits following surgical castration in men with advanced prostate cancer, and since then the androgen receptor (AR) has remained the main therapeutic target in this disease. Over the past couple of decades, our understanding of AR-signaling biology has dramatically improved, and it has become apparent that the AR can modulate a number of other well-described oncogenic signaling pathways. Not surprisingly, mounting preclinical and epidemiologic data now supports a role for AR-signaling in promoting the growth and progression of several cancers other than prostate, and early phase clinical trials have documented preliminary signs of efficacy when AR-signaling inhibitors are used in several of these malignancies. In this article, we provide an overview of the evidence supporting the use of AR-directed therapies in prostate as well as other cancers, with an emphasis on the rationale for targeting AR-signaling across tumor types.

Abstract
PURPOSE This study aims to determine the significance of androgen receptor (AR) expression in urothelial carcinoma of the upper urinary tract (UTUC). METHODS AR expression was assessed on tissue microarrays containing specimens of 737 patients with UTUC who underwent radical nephroureterectomy with curative intent. AR expression was correlated with clinical and pathological tumor features as well as recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). RESULTS Overall, AR was expressed in 11 % of tumors. AR expression was significantly associated with tumor necrosis as well as sessile and multifocal tumor growth but not with RFS, CSS or OS. AR was detected nearly twice as often in tumors of the ureter than of the pelvicalyceal system (p = 0.005). Subgroup analyses showed that the significant associations of AR with unfavorable pathologic features were exclusively attributable to tumors located in the ureter. However, in both ureteral and pelvicalyceal tumors, AR status was independent of RFS, CSS and OS. CONCLUSIONS In this cohort of patients treated with RNU, AR expression was found in approximately 10 % of UTUCs, twice as often in ureteral than in pelvicalyceal tumors. While AR expression had no impact on postoperative prognosis, it was significantly associated with unfavorable pathologic features in ureteral tumors. Steroid hormone signaling might be relevant for future investigations of differences between ureteral and pelvicalyceal tumors.

Abstract
To assess the expression status of steroid hormone receptors in upper urinary tract urothelial carcinoma (UUTUC), we immunohistochemically stained for androgen receptor (AR), estrogen receptor-α (ERα), ERβ, glucocorticoid receptor (GR), and progesterone receptor (PR) in 99 UUTUC specimens and paired non-neoplastic urothelial tissues. AR/ERα/ERβ/GR/PR was positive in 20%/18%/62%/63%/16% of tumors, which was significantly lower (except PR) than in benign urothelial tissues [57% (P < 0.001)/40% (P = 0.001)/85% (P = 0.001)/84% (P = 0.002)/13% (P = 0.489)]. There were no significant associations between each receptor expression pattern and histopathological characteristic of the tumors including tumor grade/stage. Kaplan-Meier and log-rank tests revealed no significant prognostic value of each receptor expression in these 99 patients. However, patients with UUTUC positive for either ERα or PR had a significantly higher risk of disease-specific mortality (P = 0.025), compared with those with UUTUC negative for both. PR positivity alone in pT3 or pT4 tumors was also strongly associated with the risk of disease-specific mortality (P = 0.040). Multivariate analysis further identified the expression of ERα and/or PR as a strong predictor for disease-specific mortality in the entire cohort of the patients (hazard ratio, 2.434; P = 0.037). Thus, in accordance with previous observations in bladder specimens, significant decreases in the expression of AR/ERα/ERβ/GR in UUTUC, compared with that in non-neoplastic urothelium, were observed. Meanwhile, the negativity of both ERα and PR in UUTUC as well as the negativity of PR alone in deeply invasive tumor was suggested to serve as a prognosticator.

Abstract
Epidemiologic studies have long demonstrated clear differences in incidence and progression of bladder cancer between genders suggesting that the mechanisms of development and progression in these tumors have a strong association with steroid hormonal pathways. Such observations led to preclinical studies investigating the role of androgen and estrogen receptors, as well as their cognate hormones in bladder cancer initiation and progression. Using various in vitro cell line assays and in vivo mouse models, studies have elucidated different mechanisms and signaling pathways through which these steroid receptors may participate in this disease. More recently, RNA expression data from multiple studies revealed a luminal subtype of bladder cancer that exhibited an estrogen receptor signaling pathway, making it a strong candidate for further consideration of targeted therapies in the future. Despite the promising preclinical data demonstrating potential roles for both antiandrogen and antiestrogen strategies targeting these pathways in different stages of bladder cancer, only two clinical trials are currently active and accruing patients for such clinical studies. Targeted therapies in bladder cancer are a large unmet need and have the potential to change treatment paradigms and improve oncological outcomes of patients with bladder cancer.

Abstract
A gender discrepancy exists in the incidence of both urothelial and kidney carcinomas, with more men presenting with these cancers than women. Men have a threefold greater risk of developing bladder cancer than women, but female gender has been identified as an independent adverse prognostic factor for both recurrence and progression of this disease. In particular, women with bladder cancer are often diagnosed with a higher tumour stage than men. Conclusive data on the influence of gender on outcomes of patients with upper tract urothelial carcinoma are currently lacking, although men seem to have a higher disease incidence, whereas survival outcomes might be independent of gender. Patients with renal cell carcinoma are more often men and they typically have larger tumours and higher stage and grade disease than women with this cancer. Smoking habits, tumour biology, occupational risk factors and sex steroid hormones and their receptors could have a role in these observed gender disparities. The majority of data support the theory that gender influences incidence and prognosis of urothelial and kidney cancers; men and women are different genetically and socially, making the consideration of gender a key factor in the clinical decision-making process. Thus, the inclusion of this variable in validated prognostic tables and nomograms should be discussed as a matter of importance.

Abstract
Androgen receptor (AR) is expressed in normal murine and human kidneys of both genders, but its physiologic role is uncertain. Several studies showed loss of AR in renal cell carcinoma (RCC) in conjunction with increasing clinical stage and pathological grade, but others found that higher AR expression correlated with worse outcomes. Limited functional studies with renal cell lines suggested tumor-promoting activity of AR. In this study, we queried transcriptomic, proteomic, epigenetic and survival data from The Cancer Genome Atlas (TCGA) to evaluate AR expression and its association with overall survival in three subtypes of RCC (clear cell [ccRCC], papillary [pRCC], and chromophobe [chRCC]). We found that although there was no significant difference in AR mRNA expression in ccRCC of males vs. females, AR protein expression in ccRCC was significantly higher in male compared to female patients. More importantly, higher expression of AR at both transcript and protein levels was associated with improved overall survival in both genders with ccRCC, but did not predict survival of either gender with pRCC or chRCC. Genes whose transcript levels were associated with AR mRNA levels significantly overlapped between ccRCC and pRCC, but not with chRCC, suggesting a similar transcriptional program mediated by AR in ccRCC and pRCC. Ingenuity pathway analysis also identified overlapping pathways and upstream regulators enriched in AR-associated genes in ccRCC and pRCC. Hypermethylation of CpG sites located in the promoter and first exon of AR was associated with loss of AR expression and poor overall survival. Our findings support a tumor suppressor role for AR in both genders that might be exploited to decrease the incidence or progression of ccRCC.

Abstract
There is a substantial amount of preclinical or clinical evidence suggesting that steroid hormone receptor-mediated signals play a critical role in urothelial tumorigenesis and tumor progression. These receptors include androgen receptor, estrogen receptors, glucocorticoid receptor, progesterone receptor, vitamin D receptor, retinoid receptors, peroxisome proliferator-activated receptors, and others including orphan receptors. In particular, studies using urothelial cancer tissue specimens have demonstrated that elevated or reduced expression of these receptors as well as alterations of their upstream or downstream pathways correlates with patient outcomes. This review summarizes and discusses available data suggesting that steroid hormone receptors and related signals serve as biomarkers for urothelial carcinoma and are able to predict tumor recurrence or progression.

Abstract
Men are three to four times more likely to get bladder cancer than women. The gender disparity characterizing bladder cancer diagnoses has been investigated. One hypothesis is that androgen receptor (AR) signaling is involved in the etiology and progression of this disease. Although bladder cancer is not typically described as an endocrine-related malignancy, it has become increasingly clear that AR signaling plays a role in bladder tumors. This review summarizes current findings regarding the role of the AR in bladder cancer. We discuss work demonstrating AR expression in bladder cancer and its role in promoting formation and progression of tumors. Additionally, we discuss the therapeutic potential of targeting the AR in this disease.

Changes of protein expression in prostate cancer having lost its androgen sensitivity. Int Urol Nephrol 2015; 47:1149-54.

Abstract
OBJECTIVE The majority of prostate cancers require androgen hormones for growth, and androgen ablation is an important part of the systemic treatment of advanced prostate cancer. Nevertheless, most of these cancers eventually relapse as they become less sensitive to androgen ablation and anti-androgen treatment. Elucidating the molecular events that are responsible for the conversion of androgen-sensitive cancers to androgen-refractory tumors may reveal new therapeutic opportunities. METHODS In the present study, we investigated nine androgen-sensitive and nine androgen-refractory prostate cancer samples to evaluate the expression levels of 10 selected proteins that have been implicated in oncogenesis and cancer progression. RESULTS Our immunohistochemical data show that three of the investigated proteins (i.e., minichromosome maintenance-2, methylguanine-DNA methyltransferase, and androgen receptor) are expressed at significantly different levels in the androgen-refractory cancer samples than in the androgen-sensitive tumors, whereas the expression levels of the seven other studied proteins (i.e., β-catenin, p27, p21, p16, Ki67, hypoxia-inducible factor 1 alpha, and geminin) are not significantly different regarding the two groups. CONCLUSIONS Our data suggest that the increased expression of minichromosome maintenance-2 and decreased expression of methylguanine-DNA methyltransferase related to androgen receptor are indicative of the androgen-refractory stage in prostate cancer. Further studies are required to determine whether these expression changes play a causative role in the transition of androgen-sensitive to androgen-refractory prostate cancer.
