[PMID: 37694492 PMCID: PMC10557880 DOI: 10.1002/cam4.6516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 08/23/2023] [Accepted: 08/30/2023] [Indexed: 09/12/2023] Open
Abstract
BACKGROUND Elongin A (ELOA), our previous work revealed, serves as a novel tumor suppressor in colorectal cancer. However, the function and mechanism of ELOA in other cancer types, including gastric cancer (GC), remain to be elucidated. METHODS The expression of ELOA was measured by quantitative reverse transcription-polymerase chain reaction and western blot. The effects of ELOA on GC growth and metastasis were assessed through a series of in-vitro and in-vivo assays. Furthermore, the potential mechanism of ELOA was revealed by RNA sequencing, dual luciferase reporter assay, chromatin immunoprecipitation, and rescue experiments in GC. RESULTS We uncovered increased expression of ELOA in GC tissues compared with paired normal tissues via bioinformatic analyses and our sample detection. Enhanced ELOA expression in GC tissues was obviously correlated with poor tumor differentiation, lymph node metastasis, advanced tumor stage, and a poor prognosis. A series of functional experiments showed that ELOA promoted the proliferation and metastasis of GC. Mechanistically, we revealed that the decreased levels of miR-490-3p caused the upregulation of ELOA in GC. Both RNA-seq and ChIP assays revealed that ELOA transcriptionally activated retinol-binding protein 1 (RBP1) by binding to its promotor. Furthermore, specific knockdown of RBP1 reduced the tumor-promoting ability of ELOA in GC cells. CONCLUSIONS In summary, our findings demonstrate that ELOA exerts oncogenic properties by activating RBP1 expression, providing the basis for a promising therapeutic target in GC.

Abstract
Cellular Retinol Binding Protein 1 (CRBP1) gene is a protein coding gene located on human chromosome 3q21, which codifies a protein named CRBP1. CRBP1 is widely expressed in many tissues as a chaperone protein to regulate the uptake, subsequent esterification and bioavailability of retinol. CRBP1 combines retinol and retinaldehyde with high affinity to protect retinoids from non-specific oxidation, and transports retinoids to specific enzymes to promote the biosynthesis of retinoic acid. The vital role of CRBP1 in retinoids metabolism has been gradually discovered, which has been implicated in tumorigenesis. However, the precise functions of CRBP1 in different diseases are still poorly understood. The purpose of this review is to provide an overview of the role of CRBP1 in various diseases, especially in both the promotion and inhibition of cancers, which may also offer a novel biomarker and potential therapeutic target for human diseases.

Retinol binding protein 1-dependent activation of NF- κB signaling enhances the malignancy of non-glioblastomatous diffuse gliomas. Cancer Sci 2021; 113:517-528. [PMID: 34866280 PMCID: PMC8819305 DOI: 10.1111/cas.15233] [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: 04/20/2021] [Revised: 11/12/2021] [Accepted: 11/29/2021] [Indexed: 01/06/2023] Open
Abstract
Nonglioblastomatous diffuse glioma (non‐GDG) is a heterogeneous neuroepithelial tumor that exhibits a varied survival range from 4 to 13 years based on the diverse subtypes. Recent studies demonstrated novel molecular markers can predict prognosis for non‐GDG patients; however, these findings as well as pathological classification strategies show obvious limitations on malignant transition due to the heterogeneity among non‐GDGs. Therefore, developing reliable prognostic biomarkers and therapeutic targets have become an urgent need for precisely distinguishing non‐GDG subtypes, illuminating the underlying mechanism. Nuclear factor κβ (NF‐κB) has been proved to be a significant nuclear transcriptional regulator with specific DNA‐binding sequences to participate in multiple pathophysiological processes. However, the underlying mechanism of NF‐κB activation still needs to be further investigated. Herein, our results indicated retinol‐binding protein 1 (RBP1) was significantly upregulated in the IDHWT and 1p19qNon co‐del non‐GDG subtypes and enriched RBP1 expression was markedly correlated with more severe outcomes. Additionally, malignant signatures of the non‐GDG cells including proliferation, migration, invasion, and self‐renewal were significantly suppressed by lentiviral knockdown of RBP1. To further explore the underlying molecular mechanism, bioinformatics analysis was performed using databases, and the results demonstrated RBP1 was strongly correlated with tumor necrosis factor α (TNFα)–NF‐κB signaling. Moreover, exogenous silencing of RBP1 reduced phosphorylation of IkB‐kinase α (IKKα) and thus decreased NF‐κB expression via decreasing the degradation of the IκBα protein. Altogether, these data suggested RBP1‐dependent activation of NF‐κB signaling promoted malignancy of non‐GDG, indicating that RBP1 could be a reliable prognostic biomarker and potential therapeutic target for non‐GDG.

Abstract
Background CRBP-1, a cytosolic chaperone of vitamin A, is identified in a serious number of cancers; however, its biological role in hepatocellular carcinoma (HCC) needs to be further explored. The aim of our present study is to explore the roles and mechanisms of CRBP-1 in regulating liver cancer by using in vitro and in vivo biology approaches. Methods The expression level of CRBP-1 was detected using immunohistochemistry in HCC and matching adjacent non-tumorous liver tissues. Following established stable CRBP-1 overexpressed HCC cell lines, the cell growth and tumorigenicity were investigated both in vitro and in vivo. Intracellular retinoic acid was quantified by ELISA. The relationship between CRBP-1 and WIF1 was validated by using dual luciferase and ChIP analyses. Results The low expression of CRBP-1 was observed in HCC tissues compared to the normal liver tissues, while high CRBP-1 expression correlated with clinicopathological characteristics and increased overall survival in HCC patients. Overexpression of CRBP-1 significantly inhibited cell growth and tumorigenicity both in vitro and in vivo. Moreover, overexpression of CRBP-1 suppressed tumorsphere formation and cancer stemness related genes expression in HCC. Mechanically, CRBP-1 inhibited Wnt/β-catenin signaling pathway to suppress cancer cell stemness of HCC. Furthermore, our results revealed that CRBP-1 could increase the intracellular levels of retinoic acid, which induced the activation of RARs/RXRs leading to the transcriptional expression of WIF1, a secreted antagonist of the Wnt/β-catenin signaling pathway, by physically interacting with the region on WIF1 promoter. Conclusion Our findings reveal that CRBP-1 is a crucial player in the initiation and progression of HCC, which provide a novel independent prognostic biomarker and therapeutic target for the diagnosis and treatment of HCC.

Abstract
Objective In this study, we aimed to identify prognostic immune-related genes and establish a prognostic model for laryngeal cancer based on these genes. Methods Transcriptome profiles and clinical data of patients with laryngeal cancer were downloaded from The Cancer Genome Atlas database. Integrated bioinformatics analyses were performed to identify genes associated with prognosis. Results Thirty prognostic immune-related genes for laryngeal cancer were identified. We constructed a regulatory network of prognosis comprising transcription factors and immune-related genes. Multivariate Cox regression analyses identified 15 immune-related genes in the network that were used to establish the prognostic model. The model exhibited excellent prognostic prediction ability with a high area under the curve value (0.916). The calculated risk score based on expression of the 15 immune-related genes was shown to be an independent prognostic factor for laryngeal cancer. Conclusion We identified prognostic immune-related genes and established a prognostic model for laryngeal cancer, which might help identify novel predictive biomarkers and therapeutic targets of laryngeal cancer.

Abstract
Retinol-binding protein 1 (RBP1) is involved in several physiological functions, including the regulation of the metabolism and retinol transport. Studies have shown that it plays an important role in the pathogenesis of several types of cancer. However, the role of RBP1 and its correlation with autophagy in oral squamous cell carcinoma (OSCC) pathogenesis remain unknown. In this study, RBP1 was identified as the most significantly upregulated DEPs with a >2-fold change in OSCC samples when compared to normal tissues through iTRAQ-based proteomics analysis coupled with 2D LC–MS/MS. RBP1 overexpression was significantly associated with malignant phenotypes (differentiation, TNM stage, and lymphatic metastasis) of OSCC. In vitro experiments demonstrated that RBP1 was significantly increased in OSCC tissues and cell lines compared with control group. RBP1 overexpression promoted cell growth, migration, and invasion of OSCC cells. Silencing of RBP1 suppressed tumor formation in xenografted mice. We further demonstrated that the RBP1–CKAP4 axis was a critical regulator of the autophagic machinery in OSCC, inactivation of autophagy rescued the RBP1–CKAP4-mediated malignant biological behaviors of OSCC cells. Overall, a mechanistic link was provided by RBP1–CKAP4 between primary oncogenic features and the induction of autophagy, which may provide a potential therapeutic target that warrants further investigation for treatment of OSCC.

Abstract
Introduction: In Head and Neck (HN) cancer, the High-Risk Human Papillomavirus (hr HPV) infection has been associated in about 40% of these tumors. The hr HPV infection is one of the etiological factors of several epithelial tumors; however, its association with the prognosis has not yet been established for patients with Laryngeal Squamous Cell Carcinoma (LSCC). On the other hand, Epidermal Growth Factor Receptor (EGFR) is a molecular marker widely studied in cancer and its overexpression has been associated with poor prognosis in some types of cancer, including the HN cancer. In the present study, we analyzed EGFR expression and HPV detection in a cohort of Mexican patients with LSCC and define their association with clinical-pathological and survival parameters. Methods: EGFR expression analysis was performed by immunohistochemistry assay. A tissue array was constructed based on 30 paraffin-embedded tissue samples. HPV detection was performed by PCR. The results were then compared with the clinical-pathological variables and outcome measures (Kaplan Meier and Cox analysis). Results: High expression of EGFR was observed in 43% of the samples and 20% of HPV detection. The statistical analyses provided evidence of disassociation between clinical-pathological parameters and EGFR expression, but there was an association with poor prognosis. Interestingly, HPV detection is slightly associated with good prognosis. Conclusion: Both, EGFR overexpression and HPV presence could be associated with an unfavorable prognosis in patients with LSCC, independently of other clinical-pathological factors.

Abstract
Background Tongue squamous cell carcinoma (TSCC) is one of the most common malignancies of oral squamous cell carcinomas. Cellular retinol binding protein-1 (CRBP-1) as a carrier protein transports retinol from the liver storage site to peripheral tissue. Up-regulated expression of CRBP-1 is associated with some tumor types such as prostate cancer, breast cancer and ovarian cancer as reported, but its role in TSCC remains uncertain. Methods In this study, an integrated bioinformatics analysis based on the multiple cancer microarray data sets available from Oncomine database was conducted to view the differential expression of CRBP-1 between TSCC and the adjacent non-tumorous tissues. Quantitative real-time polymerase chain reaction (qRT-PCR), western blotting (WB) and immunohistochemical (IHC) assays were performed to investigate CRBP-1 expression in 101 paraffin-embeded TSCC tissues and 48 pairs of freshly frozen tissues. Kaplan-Meier curve and univariate and multivariate Cox-regression analysis were used to estimate the association between CRBP-1 expression and patients’ prognosis. Then western blotting, MTT, transwell migration and invasion assays were performed in TSCC cell lines to investigate the effects of CRBP-1 on cellular proliferation and invasion. Results Compared with the matched adjacent non-tumorous tissues, the expression of CRBP-1 was significantly up-regulated in TSCC tissues, which correlated with the differentiation state (P = 0.003), N classification (P = 0.048), the clinical stage (P = 0.048) and death (P = 0.001). The Kaplan-Meier curve showed that TSCC patients with higher CRBP-1 expression levels had lower overall survival rates than those with lower CRBP-1 expression levels. A univariate and multivariate analysis demonstrated that CRBP-1 was an independent prognostic factor (P < 0.05). Furthermore, we knocked down CRBP-1 expression and observed that TSCC cell proliferation and invasion in vitro were significantly blocked, as determined by MTT and transwell assays. Conclusions Up-regulated expression of CRBP-1 is associated with poor prognosis in TSCC, so it might potentially serve as an additional prognostic marker, and the inhibition of CRBP-1 might provide new therapeutic approaches for TSCC.

Abstract
Purpose Adenocarcinoma, the most common non-small cell lung cancer is a leading cause of death worldwide, with a low overall survival (OS) despite increasing attempts to achieve an early diagnosis and accomplish surgical and multimodality treatment strategies. Cellular retinol binding protein-1 (CRBP-1) regulates retinol bioavailability and cell differentiation, but its role in lung cancerogenesis remains uncertain. Experimental design CRBP-1 expression, clinical outcome and other prognostic factors were investigated in 167 lung adenocarcinoma patients. CRBP-1 expression was evaluated by immunohistochemistry of tissue microarray sections, gene copy number analysis and tumor methylation specific PCR. Effects of CRBP-1 expression on proliferation/apoptosis gene array, protein and transcripts were investigated in transfected A549 lung adenocarcinoma cells. Results CRBP-1High expression was observed in 62.3% of adenocarcinomas and correlated with increased tumor grade and reduced OS as an independent prognostic factor. CRBP-1 gene copy gain also associated with tumor CRBP-1High status and dedifferentiation. CRBP-1-transfected (CRBP-1+) A549 grew more than CRBP-1− A549 cells. At >1μM concentrations, all trans-retinoic acid and retinol reduced viability more in CRBP-1+ than in CRBP-1− A549 cells. CRBP-1+ A549 cells showed up-regulated RARα/ RXRα and proliferative and transcriptional genes including pAkt, pEGFR, pErk1/2, creb1 and c-jun, whereas RARβ and p53 were strongly down-regulated; pAkt/pErk/ pEGFR inhibitors counteracted proliferative advantage and increased RARα/RXRα, c-jun and CD44 expression in CRBP-1+ A549 cells. Conclusion CRBP-1High expression in lung adenocarcinoma correlated with increased tumor grade and reduced OS, likely through increased Akt/Erk/EGFR-mediated cell proliferation and differentiation. CRBP-1High expression can be considered an additional marker of poor prognosis in lung adenocarcinoma patients.

Vitamin A, cancer treatment and prevention: the new role of cellular retinol binding proteins. BIOMED RESEARCH INTERNATIONAL 2015; 2015:624627. [PMID: 25879031 PMCID: PMC4387950 DOI: 10.1155/2015/624627] [Citation(s) in RCA: 87] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/20/2014] [Revised: 08/07/2014] [Accepted: 08/09/2014] [Indexed: 11/18/2022]
Abstract
Retinol and vitamin A derivatives influence cell differentiation, proliferation, and apoptosis and play an important physiologic role in a wide range of biological processes. Retinol is obtained from foods of animal origin. Retinol derivatives are fundamental for vision, while retinoic acid is essential for skin and bone growth. Intracellular retinoid bioavailability is regulated by the presence of specific cytoplasmic retinol and retinoic acid binding proteins (CRBPs and CRABPs). CRBP-1, the most diffuse CRBP isoform, is a small 15 KDa cytosolic protein widely expressed and evolutionarily conserved in many tissues. CRBP-1 acts as chaperone and regulates the uptake, subsequent esterification, and bioavailability of retinol. CRBP-1 plays a major role in wound healing and arterial tissue remodelling processes. In the last years, the role of CRBP-1-related retinoid signalling during cancer progression became object of several studies. CRBP-1 downregulation associates with a more malignant phenotype in breast, ovarian, and nasopharyngeal cancers. Reexpression of CRBP-1 increased retinol sensitivity and reduced viability of ovarian cancer cells in vitro. Further studies are needed to explore new therapeutic strategies aimed at restoring CRBP-1-mediated intracellular retinol trafficking and the meaning of CRBP-1 expression in cancer patients' screening for a more personalized and efficacy retinoid therapy.

Abstract
Human papillomavirus (HPV) is now recognized to cause a subset of head and neck squamous cell carcinomas (HNSCC). Although excessive tobacco and alcohol use continue to be important risk factors for HNSCC, epidemiologic studies suggest that more than 25% of HNSCC are now caused by HPV. The incidence of HPV-related HNSCC is increasing, highlighting the need to understand the oral HPV infections causing these cancers. This article reviews the evidence for a causal association between HPV and HNSCC, examines the changing epidemiologic trends of HNSCC, and discusses what is currently known about oral HPV infection, natural history, and transmission.

Clin Lung Cancer 2012; 12:328-34. [PMID: 21889114 DOI: 10.1016/j.cllc.2011.02.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2010] [Revised: 02/13/2011] [Accepted: 02/22/2011] [Indexed: 01/16/2023]
Abstract
BACKGROUND AND PURPOSE Although lung cancer is the leading cause of cancer deaths worldwide, reliable markers allowing prediction of patient survival at the time of initial diagnosis are still lacking. Copy number alterations (CNAs) in tumor tissue DNA have been associated with tumorigenesis and malignant progression. We aimed at identification of gene-level CNAs with prognostic value for survival in pulmonary squamous cell carcinoma (SCC). METHODS The CNA status of a panel of 44 genes was analyzed by high-resolution array comparative genomic hybridization (CGH) in 49 SCC samples. Overall survival information (median follow-up, 40 months) for the patients was collected and used to assess outcome correlations with gene CNAs. RESULTS Survival analysis showed that both CDKN2B loss and PTCH1 loss were associated with poor survival (both P < .001, log-rank test). Multivariate Cox analysis, including CDKN2B loss and PTCH1 loss as well as age, sex, cigarette smoking status, tumor size, tumor differentiation, and TNM stage showed that CDKN2B loss (hazard ratio [HR], 17.88; 95% confidence interval [CI], 4.40-72.67; P < .001) and PTCH1 loss (HR, 10.81; 95% CI, 1.92-60.98; P = .007) were independent prognostic factors for poor survival. In addition the PTCH1 loss was more frequently found in moderately or poorly differentiated tumors than in well-differentiated tumors (P = .007). CONCLUSION These findings suggest that 2 genes of loss, CDKN2B and PTCH1, are associated with poor overall survival in patients with SCC of the lung and may be useful as prognostic markers.

Preliminary proteomic analysis of human serum from patients with laryngeal carcinoma. Eur Arch Otorhinolaryngol 2011; 269:557-63. [PMID: 21968631 DOI: 10.1007/s00405-011-1786-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2011] [Accepted: 09/20/2011] [Indexed: 10/17/2022]
Abstract
To better evaluate the serum protein alterations in patients with laryngeal carcinoma during surgical treatment process, a comparative proteomic analysis of human serum from patients with laryngeal carcinoma between pre- and post-operation group was performed using two-dimensional gel electrophoresis, in combination with matrix-assisted laser desorption ionization time-of-flight mass spectrometry and database searching. Statistical analysis indicated that 16 gel spots corresponding to 12 proteins altered their expression significantly between the two groups of patients with laryngeal carcinoma. Of these 12 proteins, 6 proteins were up-regulated in the pre-operation group. The subsequent Western blot confirmed the results of proteome analysis. Measurement of MDA and SOD levels in serum combining with bioinformatics analysis indicated the potential roles of the oxidant stress and immune response as target in monitoring and treating laryngeal carcinoma. The study provides new insight into the laryngeal carcinoma development and treatment, and the identified proteins are warranted to be further studied.
