Ubiquitin ligase NEDD4 promotes the proliferation of hepatocellular carcinoma cells through targeting PCDH17 protein for ubiquitination and degradation. J Biol Chem 2024; 300:105593. [PMID: 38145746 PMCID: PMC10826327 DOI: 10.1016/j.jbc.2023.105593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 12/07/2023] [Accepted: 12/13/2023] [Indexed: 12/27/2023] Open
Abstract
Neural precursor cell expressed developmentally downregulated 4 (NEDD4), an E3 ubiquitin ligase, is commonly upregulated in human hepatocellular carcinoma (HCC) and functions as an oncogenic factor in the progression of HCC, but the molecular mechanism needs be further explored. In this study, we found that NEDD4 could facilitate the proliferation of HCC cells, which was associated with regulating the ERK signaling. Further investigation showed that protocadherin 17 (PCDH17) was a potential substrate of NEDD4, and restoration of PCDH17 could block the facilitation of ERK signaling and HCC cells proliferation induced by NEDD4 overexpression. Whereafter, we confirmed that NEDD4 interacted with PCDH17 and promoted the Lys33-linked polyubiquitination and degradation of it via the proteasome pathway. Finally, NEDD4 protein level was found to be inversely correlated with that of PCDH17 in human HCC tissues. In conclusion, these results suggest that NEDD4 acts as an E3 ubiquitin ligase for PCDH17 ubiquitination and degradation thereby promoting the proliferation of HCC cells through regulating the ERK signaling, which may provide novel evidence for NEDD4 to be a promising therapeutic target for HCC.

[PMID: 37902910 DOI: 10.1007/s11033-023-08818-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Accepted: 09/12/2023] [Indexed: 11/01/2023]
Abstract
BACKGROUND Cancer bladder is the most common malignant tumor affecting the urinary tract. Genetic alterations are tightly associated with the development of cancer bladder. MicroRNAs (miRNA) are small, noncoding single-stranded RNA molecules that have been linked to bladder cancer. miR-124-3pa exhibits altered expression in various types of human malignancies. DNA methyltransferase 3B (DNMT3B) is responsible for de novo DNA methylation which is a fundamental epigenetic process in carcinogenesis. This work was performed to study the expression of DNMT3B and miR 124-3pa in bladder cancer tissues, and investigate their significance in the diagnosis and prognosis of the disease. SUBJECTS & METHODS This case-control study included one hundred and six tissue samples of patients with primary urothelial bladder cancer. The tissues were separated into two parts. The first part was immediately frozen and kept at - 80 °C for total RNA extraction with subsequent detection of miR 124-3pa and DNMT3B expressions. The other part was preserved in formalin solution for histopathological examination. RESULTS There was a highly statistically significant difference between the cancerous and the normal tissues as regarding miRNA-124-3pa and DNMT3B expression (P < 0.001) for each. Also, there was a highly statistically significant strong negative correlation between miRNA-124-3pa and DNMT3B expression (r=-0.750, P < 0.001). The combined performance of miR-124-3pa and DNMT3B revealed that the cutoff point of ≥ 3.3 can be used as a predictor of the presence of cancer bladder with sensitivity of 98.1% and specificity of 80%. CONCLUSION miR-124-3pa and DNMT3B can be used as predictors of the presence of cancer bladder.

Abstract
Background Bladder carcinoma ranks tenth among all cancers worldwide predominantly affecting elderly males. Common risk factors being cigarette smoke and aniline dyes. Immunohistochemical markers play a pivotal role for its diagnosis and prognosis. Aim To analyze the immunohistochemical expression of p53, CD10, Ki-67 in bladder cancers correlating with demographic features, pathological grade, and stage and to establish as prognostic biomarkers. Materials and Methods Surgical samples of total of 70 cases of bladder tumor were collected, processed, stained in routine hematoxylin and eosin followed by immunohistochemistry of p53, CD10, and Ki67 markers performed on randomly selected 30 cases only. Results Out of 70 cases 69 cases (98.6%) were carcinomas; urothelial carcinoma being 71.4% (n = 50) with male: female ratio = 7.7:1 and mean age = 61.81 ± 12.83 years. Out of 30 cases, p53 was positive in 50% of cases, 30% - negative and 20% - equivocal. p53 positive expression pattern was more in high grade (HG) than low grade (LG). Significant difference was observed in the mean p53 scoring (%) and different stages (P = 0.043). CD10 expression was negative in 56.6%, (1+) in 16.6%, and (2+) in 26.6% of cases and significant difference in CD 10 expression was observed between the high and LG (P = 0.001). Ki-67 labeling index was appreciably higher in HG than the LG tumor (32.49% ± 24.35%; 6.86% ± 8.1%). Majority of Ki-67 expression was observed in stage pT2, followed by the pT1 stage. Conclusion Cocktail of p53, CD10, and Ki67 is useful as potential prognostic markers in bladder cancers.

Abstract
INTRODUCTION Autophagy is an intracellular process that plays a key role in the cellular homeostasis. Recently, it has been described as a potential therapeutic target in oncology, whether by activating or inhibiting its different cascades. Autophagy inhibitors interact with different molecular processes of the hallmarks of cancer. AREAS COVERED Multiple proteins of the autophagy cascade could be aimed by specific inhibitors in many tumors, notably bladder cancer. In fact, bladder cancer has been increasing in prevalence over the last decade, and resistance to conventional treatment has been extensively reported in the literature. Autophagy inhibitors in bladder cancer have been described in preclinical studies to increase the sensitivity of the tumor to chemotherapy and radiotherapy. This paper is a review of the literature, which selected randomized trials, cohort studies, and case-control studies documenting the relationship between autophagy inhibitors and bladder cancer treatment. EXPERT OPINION Autophagy is a promising pathway for cancer cell targeting that opens the horizons for a potential new therapeutic area in particular the multidisciplinary management of bladder cancer.

Abstract
OBJECTIVE Bladder cancer is one of the most common malignant tumors in urology in China. The analysis of gene mutation in bladder cancer and its relationship with clinical characteristics and prognosis will provide a basis for accurate treatment of bladder cancer. The aim of this study was to analyze the mutations and functional regions of bladder cancer-related genes based on high-throughput sequencing, and to explore the relationship between mutations and clinicopathological features, as well as its prognosis and clinical implication. METHODS From April 2020 to October 2020, a total of 47 patients with bladder cancer in the Department of Urology, Affiliated Hospital of Chengde Medical College were studied. Gene sequencing was performed using Nextseq CN500 System, a high-throughput sequencing platform. The results of gene detection were described, and the relationship and clinical value of high frequency mutated genes with clinicopathological features and prognosis were systematically analyzed. RESULTS A total of 29 mutation genes, 61 exons, and 95 mutation sites were identified in this study. The frequencies of TP53, FGFR3, PIK3CA, ERBB2, MUC4, and KRAS mutation are relatively high, accounting for 59.92 % of the total mutation frequency. The TP53 was significantly associated with muscle invasive bladder cancer, T2 stage, and progression-free survival, while FGFR3 was significantly associated with non-muscle invasive bladder cancer and T1 stage. CONCLUSION High-throughput sequencing technology provides a successful approach for detecting bladder cancer gene mutations. The TP53, FGFR3, PIK3CA, ERBB2, MUC4, and KRAS genes have high mutation frequencies in bladder cancer patients. The TP53, FGFR3 and PIK3CA genes may play a predictive role in the prognosis of bladder cancer, which may hold certain guiding significance for in-depth study of the pathogenesis of bladder cancer and the development of targeted therapies.

Abstract
Serum autoantibodies respond not only to tumor-associated antigens of hepatocellular carcinoma (HCC) but also to those of liver cirrhosis (LC) and chronic hepatitis (CH). The present prospective multi-institutional study evaluated the diagnostic properties of six autoantibodies in distinguishing HCC from LC and CH. A total of 416 participants were enrolled: 149 With HCC, 76 with LC, 103 with CH and 88 healthy controls. Titers of serum autoantibodies to Sui1, RalA, p62, p53, c-myc and NY-ESO-1 were determined using enzyme-linked immunosorbent assays. All six antibodies were positive for HCC: s-Sui1-Abs (44%), s-RalA-Abs (23%), s-p62-Abs (21%), s-p53-Abs (13%), s-c-myc-Abs (11%) and s-NY-ESO-1-Abs (6%). The positivity rates of all six antibodies combined were 5% for healthy controls, 52% for CH, 58% for LC and 66% for HCC. The positivity rates of s-Sui1-Abs, s-RalA-Abs and s-p53-Abs were higher for HCC compared with those of LC and CH. However, the positivity rates of s-p62-Abs, s-c-myc-Abs and s-NY-ESO-1-Abs for HCC were not higher compared with those for LC and CH. Overall, autoantibodies were useful in differentiating patients with HCC from healthy individuals. However, they were not specific to HCC and were also present in the sera of individuals with CH and LC. These autoantibodies may be induced during the development of HCC. Clinical trial registration number: UMIN000014530 (date of registration 2011/07/11).

Abstract
Bladder cancer is the most common malignant tumor of the urinary system. We investigated the clinical implications of cell lineages in bladder cancer by integrating single-cell and bulk transcriptome data. By investigating the single-cell transcriptional profiles of 12,424 cells from normal bladder, eleven cell types and five types of epithelial sub-population were identified. Based on the signature of cell types identified in single-cell profiles, deconvolution analysis was employed to estimate cell types and epithelial lineages in the bulk RNA sequencing bladder cancer cohort. Cancer subtypes with clinical implications were further identified based on the heterogeneity of the epithelial lineage across patients. This study suggests that the EMT-like subtype is robustly correlated with poor prognosis and the umbrella subtype is a positive factor for the patient survival. Our research has a high potential for accurate prognostic and therapeutic stratification of bladder cancer.

Abstract
BACKGROUND: Carcinoma of urinary bladder is one of the most common malignancies worldwide and constitutes a major health problem. Multiple risk factors are associated with this tumor and its prognosis will depend on different clinicopathological parameters. Over expression of P53 protein and mutant Rb gene is associated with more aggressive clinical and histopathological features of the tumor such as advanced stage and higher grade.
AIM: The immunohistochemical expression of Rb gene and P53 gene will be assessed through their protein products in transitional cell carcinoma (TCC) of the urinary bladder and then will be correlated with other well-known risk factors and prognostic parameters of bladder TCC, such as grading, tumor size, smoking, alcohol drinking, and family history.
METHODS: Patients were recruited from the uro-surgical department/Surgical Subspecialties Teaching Hospital during the period from November 2020 through April 2021. In this study, patients enrolled were those suspected to have bladder carcinoma. The work up included a full history and clinical examination. Surgical samples were taken from the patients for histopathological evaluation; the study’s samples represented either endoscopic cup biopsy, transurethral resection of the tumor, or radical cystectomy. Sections obtained from these samples were stained with the conventional hematoxylin and eosin stain. Then, immunohistochemical staining for P53 and pRB was applied only for patients diagnosed with TCC.
RESULTS: The differences between low-grade and high-grade tumors regarding pRb percentage score were statistically significant (p = 0.026), but were not significant regarding the intensity score (p = 0.094). There were significant correlations between tumor stage and both pRb intensity and percentage scores (p = 0.044 and 0.042, respectively). Differences between low-grade and high-grade tumors regarding p53 intensity score were significant (p = 0.022). The differences between low-grade and high-grade tumors regarding p53 percentage score were significant (p = 0.049). The differences between different tumor stages regarding p53 intensity score were significant (p = 0.018). The differences between different tumor stages regarding P53 percentage score were significant (p = 0.019).
CONCLUSIONS: Tumor’s grade was found to be correlated with the tumor stage with no correlation with the age, gender, smoking, family history of TCC, history of urinary tract infection, bladder stones, nor the recurrence of the tumor. The pRb intensity and the percentage scores were correlated to each other and to tumor’s grade and stage, except for the pRb intensity which showed no correlation with the tumor’s grade. The P53 intensity and percentage scores were correlated to each other and also to tumor’s grade and stage, so that P53 is over-expressed in tumors with higher grade and stage.

Abstract
Background This study aimed to assess the prognostic value of various diagnostic immunohistochemical (IHC) markers and develop an IHC-based classifier to predict the disease-free survival (DFS) of patients with bladder cancer undergoing radical cystectomy. Methods IHC was performed on tumor specimens from 366 patients with transitional cell bladder cancer. The least absolute shrinkage and selection operator (LASSO) Cox regression model was used to develop a multi-marker classifier for predicting DFS of patients with bladder cancer. The Kaplan-Meier estimate was performed to assess DFS, and unadjusted and adjusted Cox regression models were used to identify independent risk factors to predict DFS of patients with bladder cancer. Results Based on the LASSO Cox regression model, nine prognostic markers were identified in the training cohort. Patients were stratified into low- and high-risk groups using the IHC-based classifier. In the training cohort, the 10-year DFS was significantly better in low-risk patients (71%) compared with high-risk patients (18%) (p < 0.001); in the validation cohort, the 10-year DFS was 86% for the low-risk group and 20% for the high-risk group (p < 0.001). Multivariable Cox regression analyses showed that the high-risk group based on the classifier was associated with poorer DFS adjusted by clinicopathological characteristics. Finally, a nomogram comprising the classifier and clinicopathological factors was developed for clinical application. Conclusion The nine-IHC-based classifier is a reliable prognostic tool, which can eventually guide clinical decision making regarding treatment strategy and follow-up scheduling of bladder cancer.

Abstract
Bladder cancer is a disease that negatively affects patients' quality of life, but treatment options have remained unchanged for a long time. Although promising results have been achieved with current bladder cancer treatments, cancer recurrence, progression, and therapy resistance are the most severe problems preventing the efficiency of bladder cancer treatments. Autophagy refers to an evolutionarily conserved catabolic process in which proteins, damaged organelles, and cytoplasmic components are degraded by lysosomal enzymes. Autophagy regulates the therapeutic response to the chemotherapy drugs, thus determining the effect of therapy on cancer cells. Autophagy is a stress-induced cell survival mechanism and its excessive stimulation can cause resistance of tumor cells to therapeutic agents. Depending on the conditions, an increase in autophagy may cause treatment resistance or autophagic cell death, and it is related to important anti-cancer mechanisms, such as apoptosis. Therefore, understanding the roles of autophagy under different conditions is important for designing effective anti-cancer agents. The dual role of autophagy in cancer has attracted considerable attention in respect of bladder cancer treatment. In this review, we summarize the basic characteristics of autophagy, including its mechanisms, regulation, and functions, and we present examples from current studies concerning the dual role of autophagy in bladder cancer progression and therapy.

Long-term aspirin use for primary cancer prevention: An updated systematic review and subgroup meta-analysis of 29 randomized clinical trials. J Cancer 2020; 11:6460-6473. [PMID: 33033530 PMCID: PMC7532493 DOI: 10.7150/jca.49001] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Accepted: 08/24/2020] [Indexed: 12/24/2022] Open
Abstract
Background and objective: Long-term aspirin use for the primary prevention of cancer remains controversial, and variations in the effect of aspirin use on cancer outcomes by aspirin dose, follow-up duration, or study population have never been systematically evaluated. The objective of this study was to evaluate the effect of aspirin on primary cancer prevention and to determine whether the effect differed according to aspirin dose, follow-up duration, or study population. Materials and methods: Seven electronic databases were searched from inception to September 30, 2019. Randomized clinical trials (RCTs) that compared aspirin use versus no aspirin use in participants without pre-existing cancer and reported cancer outcomes were selected. Data were screened and extracted by different investigators. Analyses were performed using Review Manager 5.3 and Comprehensive Meta-Analysis 2.0. Total cancer incidence was defined as the primary clinical endpoint. Total cancer mortality, all-cause mortality, major bleeding, and total bleeding events were the secondary outcomes. Subgroup analyses were conducted based on aspirin dose, follow-up duration, and study populations. Results: Twenty-nine RCTs that randomized 200,679 participants were included. Compared with no aspirin, aspirin use was not associated with significant reductions in total cancer incidence (RR = 1.01, 95% CI: 0.97 to 1.04, P = 0.72), total cancer mortality (RR = 1.00, 95% CI: 0.93 to 1.07, P = 0.90), or all-cause mortality (RR = 0.98, 95% CI: 0.94 to 1.02, P =0.31); however, aspirin use was associated with a 44% increase in the risk of major bleeding (RR = 1.44, 95% CI: 1.32 to 1.57, P < 0.00001) and a 52% increase in the risk of total bleeding events (RR = 1.52, 95% CI: 1.33 to 1.74, P < 0.00001). Subgroup analyses demonstrated consistent results. Conclusions: Long-term aspirin use in individuals without pre-existing cancer was not associated with a significant reduction in total cancer incidence, cancer mortality, or all-cause mortality; however, aspirin use was associated with a significant increase in the risk of bleeding. Therefore, aspirin is not an appropriate choice for the primary cancer prevention.

Abstract
Beclin-1 and Bcl-2 expression abnormalities have been confirmed in different types of cancer. As important regulators of autophagy and apoptosis, respectively, these molecules serve a complex role in tumorigenesis. However, limited information is currently available regarding the association between Beclin-1 and Bcl-2 in (NSCLC). In the present study, the expression levels of Beclin-1 and Bcl-2 were detected in lung cancer tissues, and their prognostic significance was analyzed for NSCLC. A total of 120 patients with lung cancer who underwent surgical resection were included in the present study. Beclin-1 and Bcl-2 expression was assessed using immunohistochemistry and their associations with the overall survival (OS) in patients with NSCLC was examined. The expression rate of Beclin-1 was significantly lower in NSCLC tissues compared with that in adjacent tissues, whereas the expression rate of Bcl-2 was significantly higher in lung cancer tissues compared with that in adjacent tissues. Additionally, Beclin-1 and Bcl-2 protein expression was strongly associated (P<0.05) in NSCLC. Patients with NSCLC with low Beclin-1 expression were in more advanced stages, with more lymph node metastasis and more poorly differentiated tumors. Similarly, patients with NSCLC with high Bcl-2 expression were also in a more advanced stage and had more lymph node metastasis. Cox regression analysis revealed that the association between Bcl-2 expression and survival was not significant, while a multivariate analysis revealed that Beclin-1 expression was significantly associated with OS. Notably, Beclin-1 expression was significantly associated with OS only in patients with high Bcl-2 expression. In conclusion, the present data indicated that the autophagy activity is decreased in NSCLC. Beclin-1 expression was downregulated, while Bcl-2 expression was upregulated in NSCLC tissues compared with that in adjacent tissues. Additionally, these two proteins were associated with the occurrence and progression of NSCLC. Beclin-1 may be a promising prognostic marker for patients with NSCLC with high Bcl-2 expression. The present findings provided a more accurate prognostic assessment for patients with NSCLC. Furthermore, they may be used to actively follow-up and promptly treat patients with a poor prognosis, which may benefit a greater number of patients with NSCLC.

Abstract
The high occurrence of bladder cancer and its tendency to recur in combination with a lifelong surveillance make the treatment of superficial bladder cancer one of the most expensive and time-consuming. Moreover, carcinoma in situ often leads to muscle invasion with an unfavorable prognosis. Currently, invasive methods including cystoscopy and cytology remain a gold standard. The aim of this study was to explore urine-based biomarkers to find the one with the best specificity and sensitivity, which would allow optimizing the treatment plan. In this review, we sum up the current knowledge about Cytokeratin fragments (CYFRA 21.1), Excision Repair Cross-Complementation 1 (ERCC1), Tumour Protein p53 (Tp53), Fibroblast Growth Factor Receptor 3 (FGFR3), Tumor-Associated Trypsin Inhibitor (TATI) and their potential applications in clinical practice.

Abstract
Bladder cancer (BCa) is one of the most common malignancies and has a relatively poor outcome worldwide. However, the molecular mechanisms and processes of BCa development and progression remain poorly understood. Therefore, the present study aimed to identify candidate genes in the carcinogenesis and progression of BCa. Five GEO datasets and TCGA-BLCA datasets were analyzed by statistical software R, FUNRICH, Cytoscape, and online instruments to identify differentially expressed genes (DEGs), to construct protein‒protein interaction networks (PPIs) and perform functional enrichment analysis and survival analyses. In total, we found 418 DEGs. We found 14 hub genes, and gene ontology (GO) analysis revealed DEG enrichment in networks and pathways related to cell cycle and proliferation, but also in cell movement, receptor signaling, and viral carcinogenesis. Compared with noncancerous tissues, TPM1, CRYAB, and CASQ2 were significantly downregulated in BCa, and the other hub genes were significant upregulated. Furthermore, MAD2L1 and CASQ2 potentially play a pivotal role in lymph nodal metastasis. CRYAB and CASQ2 were both significantly correlated with overall survival (OS) and disease-free survival (DFS). The present study highlights an up to now unrecognized possible role of CASQ2 in cancer (BCa). Furthermore, CRYAB has never been described in BCa, but our study suggests that it may also be a candidate biomarker in BCa.
