Abstract
INTRODUCTION Studies in recent years have shown that ribosome-binding protein-1 (RRBP1) is expressed at high rates in many cancers and that it may be a potential prognostic biomarker. The objective of the present study is to determine the RRBP1 expression level in prostatic carcinoma and neighboring non-neoplastic prostate tissue, the relationship between its expression level with prognostic factors, and the role of RRBP1 in the development of prostate cancer. MATERIALS AND METHODS The study included 45 patients who were diagnosed with prostatic carcinoma and underwent radical prostatectomy in our center between the years 2010 and 2021. Pathology reports were reviewed. Mann-Whitney U test was used for the comparison of RRBP1 and GADPH values of the cases (control and tumoral tissue) between the primary tumor stage (pT) and Gleason score (GS) groups. Hierarchical regression analysis was used to explain the effective variables in explaining the RRBP1 value of the research cases. RESULTS According to the Mann-Whitney U test, mean and median RRBP1-T values of the cases with GS ≥ 8 were detected to be statistically significantly higher than the mean and median RRBP1-T values of the cases with GS < 8. CONCLUSION We found out that RRBP1 was expressed at higher rates in patients with high GS and advanced-stage patients. This result indicated that RRBP1 expression may be important in predicting the prognosis of prostate carcinoma.

Reprod Biol Endocrinol 2022; 20:161. [PMID: 36411474 PMCID: PMC9677646 DOI: 10.1186/s12958-022-01031-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 11/03/2022] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Mammalian sperm maturation in the epididymis is mainly modulated by exosomes that are secreted into the epididymal lumen from epididymal epithelial cells (EECs). Exposure to oxidative stress (OS) resulting from being fed a high fat diet (HFD) reduces sperm fertility, which is one of the cause inducing male infertility. Thus, we hypothesize that stress-induced changes in exosome content play a critical role in mediating this detrimental process. METHODS: An obese mouse model was established by feeding a HFD. Then oxidative stress status was measured in the mouse caput epididymis, epididymal fluid and spermatozoa. Meanwhile, epididymis-derived purified exosomes were isolated and validated. Subsequently, liquid chromatography tandem mass spectrometry (LC-MS) was used to perform proteomic analysis of purified exosomes. Gene Ontology (GO) analysis was performed along with pathway enrichment to identify differentially expressed proteins (DEPs). RESULTS Two hundred and two DEPs mostly related to endoplasmic reticulum (ER) function were identified in the exosomes separated from the epididymis of control mice and obese mice. The ER stress and CD63 (an exosome marker), both increased in the caput epididymis of obese mice. Furthermore, an in vitro study showed that palmitic acid (PA), an-oxidative stress inducer, increased exosome biogenesis and secretion in the EECs. CONCLUSION Oxidative stress in the epididymal microenvironment induces ER stress in the EECs. This effect alters the epididymis-derived exosome content, profile and amounts of their differentially expressed ER proteins. Such changes may affect exosome biogenesis and cargo packaging, finally leading to abnormalities in sperm maturation and fertility.

Mol Oncol 2021; 16:1572-1590.

Abstract
Deubiquitinating enzymes (DUBs) serve to maintain cellular homeostasis via protein ubiquitination and exert diverse regulatory functions in cancers and other diseases. Much progress has been made in characterizing biological roles of DUBs over the decades, yet the specific functions of many subclass members remain largely unexplored. It was not until recent years that the role of ubiquitin‐specific‐processing protease 35 (USP35) in cancers began to be understood. Here, we focus on delineating the roles and underlying mechanisms of USP35 in non‐small cell lung cancer (NSCLC). The isobaric tags for relative and absolute quantitation (iTRAQ) comparative proteomic approach were employed to identify differentially expressed proteins (DEPs) in H1299 cells induced by USP35 overexpression or silencing. Among the potential interactome of USP35, ribosome‐binding protein 1 (RRBP1), a membrane‐bound protein in endoplasmic reticulum (ER), captured our attentions. RRBP1 expression was found to positively correlate with USP35 levels in both genetically modified cells and human NSCLC tissues. Concordantly, both RRBP1 expression and USP35 expression were found to positively correlate with poor prognoses in lung adenocarcinoma patients. At the molecular level, USP35 was verified to directly interact with RRBP1 to prevent it from proteasomal‐dependent degradation. Functionally, USP35 alleviated ER stress‐induced cell apoptosis by stabilizing RRBP1 in NSCLC cells. Collectively, these findings indicate that USP35 plays a critical role in resisting ER stress‐induced cell death through deubiquitinating RRBP1, hence providing a rationale to target the USP35‐RRBP1 axis as an alternative therapeutic option for NSCLC.

Abstract
Ribosome-binding protein 1 (RRBP1) is a potential oncogene in several cancer types. However, the correlation between RRBP1 expression and the prognosis of patients with upper tract urothelial carcinoma (UTUC) remains unclear. In this study, we identified that RRBP1 is associated with carcinogenesis and metastasis in UTUC using a methylation profiling microarray. High correlations between RRBP1 and cancer stages, nodal metastasis status, molecular subtypes, and prognosis in bladder urothelial cancer (BLCA) were found. Aberrant DNA methylation in the gene body region of RRBP1 was determined in UTUC tissues by methylation-specific PCR. RRBP1 expression was significantly increased in UTUC tissues and cell lines, as determined by real-time PCR and immunohistochemistry. RRBP1 depletion significantly reduced BFTC909 cell growth induced by specific shRNA. On the other hand, molecular subtype analysis showed that the expression of RRBP1 was associated with genes related to cell proliferation, epithelial-mesenchymal transition, and basal markers. A patient-derived organoid model was established to analyze patients' responses to different drugs. The expression of RRBP1 was related to chemoresistance. Taken together, these results provide the first evidence that RRBP1 gene body hypomethylation predicts RRBP1 high expression in UTUC. The data highlight the importance of RRBP1 in UTUC malignancy and chemotherapeutic tolerance.

Abstract
BACKGROUND Chemoresistance is one of the major factors for treatment failure in OSCC. Identifying key resistance triggering molecules will be useful strategy for developing novel treatment methods. METHODS To identify the causative factors of chemoresistance, we performed RNA sequencing and global proteomic profiling of human OSCC lines presenting with sensitive, early and late cisplatin-resistance patterns. RESULTS From the common set of dysregulated genes from both the analysis, RRBP1 was identified to be upregulated in both early and late cisplatin-resistant cells with respect to the sensitive counterpart. Analysis of OSCC patient sample indicates that RRBP1 expression is upregulated in chemotherapy-non-responder tumours as compared to chemotherapy-responder tumours. Genetic (knockout) or pharmacological (Radezolid, represses expression of RRBP1) inhibition of RRBP1 restores cisplatin-mediated cell death in chemo-resistant OSCC. Mechanistically, RRBP1 regulates Yes-associated protein1 (YAP1), a key protein in the Hippo pathway to induce chemoresistance. The PDC xenograft data suggests that knockout of RRBP1 induces cisplatin-mediated cell death and facilitates a significant reduction of tumour burden. CONCLUSION Overall, our data suggests that (I) RRBP1 is a major driver of cisplatin-resistance in OSCC, (II) RRBP1 regulates YAP1 expression to mediate cisplatin-resistance, (III) Radezolid represses RRBP1 expression and (IV) targeting RRBP1 reverses cisplatin-induced chemoresistance in advanced OSCC.

Abstract
Ribosome-binding protein 1 (RRBP1) is a marker for colorectal, lung, esophageal and prostate cancer. However, the association between RRBP1 and bladder cancer is not completely understood. The present study aimed to evaluate the expression and function of RRBP1 in bladder cancer. The association between RRBP1 expression and clinicopathological characteristics, as well as the prognosis of bladder cancer was analyzed. RRBP1 expression was further analyzed in bladder cancer cell lines via reverse transcription-quantitative PCR and western blotting. RRBP1 knockdown was established using short hairpin RNAs to investigate the function of RRBP1 in T24 cells. Compared with healthy bladder tissue, RRBP1 expression levels were significantly upregulated in bladder cancer tissue. High RRBP1 expression was associated with tumor stage, lymph node metastasis and shorter overall survival time. RRBP1 protein was highly expressed in bladder cancer cell lines compared with normal SV-HUC-1 cells. Compared with the control group, RRBP1 knockdown inhibited T24 migration and invasion by downregulating the expression of C-C chemokine receptor type 7 (CCR7) protein. In conclusion, the present study indicated that RRBP1 was associated with bladder cancer migration, invasion and prognosis, and CCR7 might serve a role in the process.

Abstract
Introduction Ribosome binding protein 1 (RRBP1) is reported to be correlated with tumor formation and progression. However, the role of RRBP1 in bladder cancer is unclear. In this study, we aimed to investigate the expression of RRBP1 and its influence on cell proliferation in bladder cancer. Methods Quantification real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry (IHC) were used to detect the expression levels of RRBP1 in 138 bladder cancer and matched adjacent normal bladder tissues. Then, the clinical significance of RRBP1 in bladder cancer was evaluated. The effect of RRBP1 on cell proliferation and its potential mechanism were further explored. Results Results show that the mRNA levels of RRBP1 in bladder cancer were significantly higher compared with those in normal tissues (P< 0.001). IHC results show the high-expression rate of RRBP1 in bladder cancer was 68.8%, which was significantly greater than those in normal tissues (40.6%, P< 0.001). RRBP1 high-expression was significantly associated with differentiation, T stage and lymph node metastasis in bladder cancer (P< 0.05). The overall survival time of patients with RRBP1 high-expression was significantly reduced compared to those with RRBP1 low-expression. Moreover, RRBP1 overexpression significantly promoted cell proliferation, which was correlated with Smad1/Smad3/TGF-β1 signal pathway. Conclusion RRBP1 high-expression correlates with prognosis and promotes cell proliferation in bladder cancer, which could be a potential biomarker.

Abstract
Our purpose was to evaluate the correlation between endoplasmic reticulum ribosomal binding protein 1 (RRBP1) expression in cervical squamous cell carcinoma (CSCC) and poor patient prognosis. RRBP1 is a nascent transporter that is situated on the rough endoplasmic reticulum (ER). It adjusts to the secretion of proteins in cells and alleviates ER stress, thus stimulating cell proliferation. An immunohistochemical (IHC) study was conducted to detect the expression level of RRBP1 on 96 CSCC tissue samples. Western blot and Quantitative real-time polymerase chain reaction (qRT-PCR) were performed to compare the expression levels of RRBP1 in cervical squamous cell carcinoma with healthy cervical tissues. An overexpression of RRBP1 was observed in CSCC tissues, and the expression level was associated with FIGO stage (Stage I vs. II: 52.6% vs. 74.1%, p = 0.030), and lymph node metastasis (No vs. Yes: 61.5% vs. 92.3%, p = 0.031) but not patient age and tissue differentiation. Univariate survival analysis indicated that prognosis was associated with the expression level of RRBP1 and tissue differentiation and lymph node metastasis. Analysis of the multi-factor survival Cox model proved that RRBP1 was an independent prognostic factor. In conclusion, compared with healthy cervical tissues, RRBP1 was overexpressed in CSCC tissues, illustrating that RRBP1 may be a new biomarker for the diagnosis of CSCC. The study on RRBP1 may contribute to exploring the pathogenesis of CSCC and may also guide targeted therapy for CSCC in the future.

Abstract
AIMS Diabetes is considered as one of the important risks in the progression of Hepatocellular carcinoma(HCC). Ribosome binding protein 1 (RRBP1), a rough endoplasmic reticulum protein, plays an essential role in diabetes and various cancer. E2F transcription factor 1 (E2F1), an upstream transcription factor of RRBP1, shows promoting tumor progression effect in multifarious cancers. In this research, we tried to identify whether regulating E2F1/RRBP1 pathway could inhibit the proliferation and metastasis of HepG2 cells induced by high glucose. MAIN METHODS Proteomic, bioinformatics, molecular biology including RT-qPCR and Western blot, cell biology containing Cell Counting Kit-8 (CCK-8), wound healing assay and transwell assay, and biochemistry analyses incorporating Luciferase assay and CHIP assay were used in this study. KEY FINDINGS High glucose promoted the proliferation and metastasis of HepG2 cells through up-regulating the expression of RRBP1. Bioinformatics analysis predicted that E2F1 might be the transcription factor of RRBP1. Knocking-down of E2F1 down-regulated mRNA and protein expression levels of RRBP1 in HepG2 cells significantly and suppressed the proliferation, migration and invasion of cells remarkably, Reverse effect was observed in cells that E2F1 was overexpressed. Meanwhile, luciferase and CHIP assay determined that E2F1 could bind to the RRBP1 promoter and promote the transcription of RRBP1. Finally, rescue assay verified the important role of RRBP1/E2F1 axis in the process of HepG2 cells proliferation and metastasis. SIGNIFICANCE All of the above provided possibility to improve the efficiency of HCC complicated with diabetes treatment by regulating the E2F1/RRBP1 pathway.

Li T, Wang Q, Hong X, Li H, Yang K, Li J, Lei B. RRBP1 is highly expressed in prostate cancer and correlates with prognosis. Cancer Manag Res 2019; 11:3021-3027. [PMID: 31118771 PMCID: PMC6503199 DOI: 10.2147/cmar.s186632] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Accepted: 02/08/2019] [Indexed: 12/11/2022] Open
Abstract
Objective: Recently, ribosome binding protein 1 (RRBP1) is reported to be involved in tumorigenesis. However, the expression and clinical significance of RRBP1 in prostate cancer (PCa) remains unknown. This study is aimed to investigate the expression and clinical significance of RRBP1 in PCa.
Materials and methods: RRBP1 expression was firstly detected in 6 cases of PCa and matched adjacent non-cancerous prostate tissues by reverse transcription-quantitative PCR (RT-qPCR) and Western blot. Then, RRBP1 expression was further detected in 127 cases of PCa and 40 cases of non-cancerous prostate tissues by immunohistochemistry (IHC). The relationship of RRBP1 with clinical-pathological characters and patients’ prognosis was analyzed in PCa. Results: RT-qPCR and Western blot analysis showed that RRBP1 expression levels in PCa tissues were significantly higher compared with those in matched adjacent non-cancerous prostate tissues. IHC results shown that the high-expression rate of RRBP1 in PCa was 69.3%, which was significantly greater than those in non-cancerous prostate tissues (15.0%, P<0.001). RRBP1 expression was significantly associated with T stage, lymph node metastasis, PSA and Gleason score in PCa. Survival analysis indicated that patients with RRBP1 low-expression presented longer survival time compared with those with RRBP1 high-expression. Moreover, RRBP1 as well as T stage, lymph node metastasis and Gleason score could serve as independent prognostic factors in PCa. Conclusion: RRBP1 is highly expressed in PCa and correlates with prognosis, which may serve as a potential biomarker in PCa.

[PMID: 30684972 PMCID: PMC6347782 DOI: 10.1186/s13000-019-0784-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2018] [Accepted: 01/15/2019] [Indexed: 01/08/2023] Open
Abstract
Background Currently, ribosome-binding protein 1 (RRBP1) is considered to be a novel oncogene that is overexpressed in colorectal cancer, lung cancer, mammary cancer, esophageal cancer and other carcinomas. However, the relationship between RRBP1 and endometrioid-type endometrial carcinoma (EC) remains unknown. Our purpose is to explore the function of RRBP1 in endometrioid-type endometrial carcinoma. Methods We investigated the expression of RRBP1 protein by immunohistochemistry on paraffin-embedded surgical specimens from one hundred thirty patients with endometrioid-type endometrial carcinoma. We also evaluated the differences in RRBP1 expression between endometrial cancer samples (n = 35) and normal endometrial tissues (n = 19) by western blotting. Results RRBP1 was more highly expressed in endometrial cancer samples than in normal samples (P < 0.05). High levels of expression of RRBP1 were strongly correlated with pathological features, such as the Federation of Gynecology and Obstetrics (FIGO) stage, histological grade, depth of myometrial invasion and lymph node metastasis (P < 0.05). Furthermore, RRBP1 expression was an independent prognostic factor for overall survival (OS) and disease-free survival (DFS) in patients with EC (both P < 0.05). Conclusion This experiment identifies the utility of RRBP1 in predicting EC prognosis, revealing that it may be a potential target for therapeutics of EC.
