Abstract
Background Current methods used to diagnose and prognosticate oropharyngeal cancer have contributed to unfavorable patient survival rates that have not significantly improved for the last several decades. Precision medicine oncology relies on molecular diagnostics and biomarkers to supplement existing methods of detecting and prognosticating cancers. This study evaluated the expression of DJ-1, an oncogene that is implicated in the pathogenesis of oral squamous cell carcinoma (OSCC), the most common type of head and neck cancer, to determine its utility as a diagnostic and prognostic biomarker. Methodology Immunohistochemistry (IHC) was performed on 13 normal oral mucosa tissue samples and 143 OSCC tissue samples of varying histopathological grades. Computer-assisted image analysis was performed using the Aperio ImageScope software from Leica Biosystems (Buffalo Grove, IL), which utilizes an algorithm of positive pixel counting for the quantification of immunoreactivity and the percentage of positive cell staining, generating a histo-score (H-score). The comparisons of the average H-scores of the different groups were made using a two-tailed T-test with P ≤ 0.05 set as the level of significance. Results The study found a significant increase in DJ-1 expression in oral squamous cell carcinoma tissue samples in comparison to the normal oral mucosa tissue samples. Additionally, the study documented a significant upregulation in DJ-1 expression in the OSCC tissue samples with high histopathological grades compared to the OSCC tissue samples with low histopathological grades. Conclusions DJ-1 expression patterns were able to reliably differentiate between oral squamous cell carcinoma and the normal counterpart tissues of the oral mucosa, thereby highlighting its role as a potential diagnostic biomarker. Moreover, DJ-1 expression significantly correlates with the OSCC histological grade, which serves as an indicator of the differentiation status and a predictor of the biological behavior of malignant neoplasms, adding to DJ-1's potential utility as a prognostic biomarker for this common type of head and neck cancer.

Abstract
INTRODUCTION PARK7/DJ-1 is an oncogene that is associated with tumorigenesis in many cancers. Recent studies have demonstrated the importance of DJ-1 in the origin and development of uveal melanoma (UM). We present an analysis of the role of the DJ-1 protein in UM cells, especially in its effect on proliferation and migration. METHODS UM cells from a primary tumor, Mel 270, and its liver metastasis, OMM2.5, were transfected with lentiviral-delivered shRNA against PARK7/DJ-1. Evaluation of cell migration and proliferation was performed using the xCELLigence real-time cell analyzer (RTCA). The effect of DJ-1 inhibition on the PTEN-Akt signaling pathway was also studied by immunoblotting. RESULTS The silencing of PARK7/DJ-1 oncoprotein expression produced a significant decrease of phosphorylated Akt (S473) in Mel270 and in metastatic OMM2.5 UM cells with no alteration on tumor suppressor PTEN expression. The diminution of PARK7/DJ-1 expression significantly inhibited real-time proliferation and invasion of Mel270 and OMM2.5 and the invasion potential of the metastatic cells. CONCLUSION DJ-1 appears to play a key role on the PTEN/Akt pathway in UM. DJ-1 inhibition appears to have a negative effect on proliferation and invasion of UM cells. This suggests DJ-1 as a potential therapeutic target in UM.

Identifying chronic alcoholism drug disulfiram as a potent DJ-1 inhibitor for cancer therapeutics. Eur J Pharmacol 2022; 926:175035. [PMID: 35605658 DOI: 10.1016/j.ejphar.2022.175035] [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: 01/14/2022] [Revised: 05/10/2022] [Accepted: 05/12/2022] [Indexed: 01/29/2023]
Abstract
As a key regulator involved in tumor development and progression, DJ-1 has been proposed as a potential therapeutic target against cancer. Also, the development of DJ-1 inhibitors holds great interests in cancer treatment. In the current study, by utilizing a small molecule covalent compounds library screening, we found that disulfiram (DSF), an FDA-approved chronic alcoholism drug, is a potent DJ-1 inhibitor. Glyoxalase assay and microscale thermophoresis analysis suggested that DSF exhibits strong inhibitory activity and high affinity to DJ-1 protein. Additionally, DSF similarly inhibited the methylglyoxal detoxification function of DJ-1 protein at the intracellular level. Notably, we discovered that DSF could significantly enhance N-(4-hydroxyphenyl) retinamide-based proliferation inhibition and apoptosis induction in different types of cancer cell lines, but not in normal tissue lines. Thus, our data suggest DSF functions as a potential inhibitor targeting DJ-1, which may provide a potential synergistic treatment option for cancer therapy.

Abstract
Highly keratinized oral squamous cell carcinoma (OSCC) exhibits an improved response to treatment and prognosis compared with weakly keratinized OSCC. Therefore, we aimed to develop gene transcript signature and to identify novel full-length isoforms, fusion transcript and non-coding RNA to differentiate well-differentiated (WD) with Moderately Differentiated (MD)/Poorly Differentiated (PD)/WD-lymphadenopathy OSCC through, HTA, Isoform sequencing, and NanoString. Additionally, specific copy number gain and loss were also identify in WD keratinized OSCC through Oncoscan array and validated through Real-time PCR in histopathologically characterized FFPE-WD keratinized OSCC. Three-hundred-thirty-eight (338) differentially expressed full-length (FL) transcript isoforms (317 upregulated and 21 down-regulated in OSCC) were identified through Isoform Sequencing using the PacBio platform. Thirty-four (34) highly upregulated differentially expressed transcripts from IsoSeq data were also correlated with HTA2.0 and validated in 42 OSCC samples. We were able to identify 18 differentially expressed transcripts, 12 fusion transcripts, and two long noncoding RNAs. These transcripts were involved in increased cell proliferation, dysregulated metabolic reprogramming, oxidative stress, and immune system markers with enhanced immune rearrangements, suggesting a cancerous nature. However, an increase in proteasomal activity and hemidesmosome proteins suggested an improved prognosis and tumor cell stability in keratinized OSCC and helped to characterize WD with MD/PD/WD with lymphadenopathy OSCC. Additionally, novel isoforms of IL37, NAA10, UCHL3, SPAG7, and RAB24 were identified while in silico functionally validated SPAG7 represented the premalignant phenotype of keratinized (K4) OSCC. Most importantly we found copy number gain and overexpression of EGFR suggest that TKIs may also be used as therapeutics in WD-OSCCs.

Exp Ther Med 2020; 19:3337-3347.

Abstract
Tongue squamous cell carcinoma (TSCC) is a common malignancy in oral cancer with a high mortality and morbidity. The ectodysplasin-A receptor-associated adaptor protein (EDARADD) is a death domain-containing adaptor protein that interacts with the TNF family ligand ectodysplasin A receptor. It is known that EDARADD has an effect on the development of ectodermal derivative tissues, such as hair and teeth. EDARADD expression is also associated with the development of melanoma. However, the role of EDARADD in TSCC remains unknown. The aim of the present investigation was to explore whether EDARADD plays a role in the biological function of TSCC. Immunohistochemistry was used to measure the expression of EDARADD in TSCC tissues and adjacent normal tissue. EDARADD was knocked down in a TSCC cell line in vitro using a specific lentivirus. The expression level of the EDARADD gene and the efficacy of gene knockdown were evaluated by reverse transcription-quantitative PCR, while EDARADD protein expression and the expression levels of Bcl-2, MYC and NF-κBp65 were determined by western blotting. Additionally, MTT assays, colony formation assays and apoptosis assays were carried out to examine the effect of EDARADD knockdown on the TSCC cells. A previous study showed that the majority of the TSCC tissues that were tested had high EDARADD expression. The expression of EDARADD both at mRNA and protein levels was significantly lower (P<0.01) after the gene was knocked down in the CAL27 cells compared with the level in control cells. Downregulation of EDARADD expression inhibited colony formation and proliferation and induced apoptosis of CAL27 cells when compared to control cells (P<0.01). Taken together, these results suggested that EDARADD may be actively involved in the progression of TSCC and that EDARADD may be a novel therapeutic target for the treatment of TSCC.

Rosmarinic acid exerts an anticancer effect on osteosarcoma cells by inhibiting DJ-1 via regulation of the PTEN-PI3K-Akt signaling pathway. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2020; 68:153186. [PMID: 32088353 DOI: 10.1016/j.phymed.2020.153186] [Citation(s) in RCA: 43] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Revised: 01/02/2020] [Accepted: 02/07/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND Osteosarcoma is the most common type of primary malignant bone tumor. This disease has exhibited a progressively lower survival rate over the past several decades, which has resulted in it becoming a main cause of death in humans. Rosmarinic acid (RA), a water-soluble polyphenolic phytochemical, exerts powerful anticancer effects against multiple types of cancer; however, its potential effects on osteosarcoma remain unknown. Hence, the present study investigated the efficacy of RA against osteosarcoma and aimed to clarify the mechanisms underlying this process. METHODS The effects of RA on cell viability, apoptosis, cell cycle distribution, migration, invasion, and signaling molecules were analyzed by CCK-8 assay, flowcytometric analysis, wound healing assay, Transwell assay, proteomic analysis, and use of shRNAs. RESULTS RA exerted anti-proliferation and pro-apoptotic effects on U2OS and MG63 osteosarcoma cells. Apoptosis was induced via extrinsic and intrinsic pathways by increasing the Bax/Bcl-2 ratio, triggering the intracellular production of reactive oxygen species (ROS), reducing the mitochondrial membrane potential (MMP), and upregulating the cleavage rates of caspase-8, caspase-9, and caspase-3. Additionally, RA suppressed the migration and invasion of osteosarcoma cells by inhibiting the expression levels of matrix metalloproteinase-2 and -9 (MMP-2 and -9), which are associated with a weakening of the epithelial-mesenchymal transition (EMT). Moreover, proteomic analyses identified DJ-1 as a potential target for RA. Several studies have indicated an oncogenic role for DJ-1 using knockdowns via the lentiviral-mediated transfection of shRNA, which caused the conspicuous suppression of cell proliferation, migration, and invasion as well as the arrest of cell cycle progression. At the molecular level, the expression levels of DJ-1, p-PI3K, and p-Akt were reduced, whereas the protein levels of phosphatase and tensin homologue (PTEN) were increased. CONCLUSION In conjunction with the high levels of DJ-1 expression in osteosarcoma tissues and cell lines, the present results suggested that RA exhibited anticancer effects in osteosarcoma cells by inhibiting DJ-1 via regulation of the PTEN-PI3K-Akt signaling pathway. Therefore, DJ-1 might be a biological target for RA in osteosarcoma cells.

miR-125b suppresses oral oncogenicity by targeting the anti-oxidative gene PRXL2A. Redox Biol 2019; 22:101140. [PMID: 30785086 PMCID: PMC6383183 DOI: 10.1016/j.redox.2019.101140] [Citation(s) in RCA: 54] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2018] [Revised: 01/22/2019] [Accepted: 02/08/2019] [Indexed: 12/11/2022] Open
Abstract
Oral squamous cell carcinoma (OSCC) is a globally prevalent malignancy. The molecular mechanisms of this cancer are not well understood and acquire elucidation. Peroxiredoxin like 2A (PRXL2A) has been reported to be an antioxidant protein that protects cells from oxidative stress. Our previous study identified an association between PRXL2A upregulation in OSCC and a worse patient prognosis. MicroRNAs (miRNAs) are small non-coding RNAs that are involved in the modulation of biological/pathological properties. The miR-125 family of genes drive pluripotent regulation across a wide variety of cancers. In this study, we identify the oncogenic eligibility of PRXL2A and clarify miR-125b as its upstream regulator. Downregulation of miR-125b can be observed in OSCC tumors. Lower miR-125b expression in tumors results in a worse patient prognosis at the relatively early stage. Reporter assays are able to validate that PRXL2A is a direct target of miR-125b. Exogenous miR-125b expression in OSCC cells results in increased oxidative stress, increased drug sensitivity, and suppressor activity that is paralleled by the knockout of PRXL2A gene. The suppressor activity of miR-125b is able to be rescued by PRXL2A, which suggests the existence of a miR-125b-PRXL2A regulatory axis that is part of OSCC pathogenesis. Nuclear factor-erythroid 2-related factor 2 (NRF2) was found to be a downstream effector of the miR-125b-PRXL2A cascade. As a whole, this study has pinpointed novel clues demonstrating that downregulation of miR-125b suppressor underlies upregulation of PRXL2A in OSCC, and this then protects the affected tumor cells from oxidative stress.

Abstract
The ribonuclease A superfamily is a vertebrate-specific family of proteins that encompasses eight functional members in humans. The proteins are secreted by diverse innate immune cells, from blood cells to epithelial cells and their levels in our body fluids correlate with infection and inflammation processes. Recent studies ascribe a prominent role to secretory RNases in the extracellular space. Extracellular RNases endowed with immuno-modulatory and antimicrobial properties can participate in a wide variety of host defense tasks, from performing cellular housekeeping to maintaining body fluid sterility. Their expression and secretion are induced in response to a variety of injury stimuli. The secreted proteins can target damaged cells and facilitate their removal from the focus of infection or inflammation. Following tissue damage, RNases can participate in clearing RNA from cellular debris or work as signaling molecules to regulate the host response and contribute to tissue remodeling and repair. We provide here an overall perspective on the current knowledge of human RNases’ biological properties and their role in health and disease. The review also includes a brief description of other vertebrate family members and unrelated extracellular RNases that share common mechanisms of action. A better knowledge of RNase mechanism of actions and an understanding of their physiological roles should facilitate the development of novel therapeutics.

Abstract
DJ-1 is a gene involved in various cellular processes, including transcriptional regulation, oxidative stress response, fertilization, mitochondrial regulation, inflammatory and fibrogenic niche formation, and glycation damage prevention. Although a disease-associated genetic study within the past decade has demonstrated that the mutation of DJ-1 is associated with autosomal early-onset Parkinson's disease, increasing evidence suggests that DJ-1 also plays a critical role in tumor development and progression. In this review, we provide an overview of current knowledge concerning the role and the mechanism of DJ-1 in cancer and also discuss the possibility of DJ-1 as a therapeutic target against cancer.

Abstract
Background The development of oral squamous cell carcinoma (OSCC) involves genetic mutations, epigenetic gene expression modification, and other processes. It has been reported that IFI27 is upregulated in OSCC, but its function is unknown. The aim of this study was to investigate the role of IFI27 on OSCC cell proliferation and invasion. Methods The protein level of IFI27 in OSCC tissues and adjacent tissues was detected by immunohistochemistry. In the OSCC cell model, we designed the IFI27 siRNA to downregulate the expression of IFI27; gene and protein of IFI27 in those models were then detected by Q-PCR and Western blot. MTT assay was used to detect the effect of -IFI27 knockdown on cell proliferation; Annexin V-PI staining flow cytometry was used to detect the effect of IFI27 downregulation on apoptosis of cancer cells. The effect of IFI27 downregulation on oral cancer cell invasion was detected using Transwell assay. Results IFI27 was highly expressed in OSCC tissues by immunohistochemical assay. In the OSCC cell model, IFI27 siRNA could downregulate the mRNA and protein expression level of IFI27. As showed in MTT assay, Annexin V-PI assay, and Transwell assay, through the downregulation of IFI27, TSCCA and TCA8113 cell proliferation were inhibited, OSCC cell apoptosis was promoted, and its migration and invasion were inhibited. Conclusion IFI27 is involved in the development and progression of OSCC. Its high expression promotes cell proliferation and invasion and reduces apoptosis. These findings may provide new biomarkers and therapeutic targets for OSCC diagnosis and clinical treatment.

Abstract
Metastasis represents a key factor associated with poor prognosis of head and neck squamous cell carcinoma (HNSC). However, the underlying molecular mechanisms remain largely unknown. In this study, our liquid chromatography with tandem mass spectrometry analysis revealed a number of significantly differentially expressed membrane/membrane-associated proteins between high invasive UM1 and low invasive UM2 cells. One of the identified membrane proteins, Syntenin-1, was remarkably up-regulated in HNSC tissues and cell lines when compared to the controls, and also over-expressed in recurrent HNSC and high invasive UM1 cells. Syntenin-1 over-expression was found to be significantly associated with lymph node metastasis and disease recurrence. HNSC patients with higher syntenin-1 expression had significantly poorer long term overall survival and similar results were found in many other types of cancers based on analysis of The Cancer Genome Atlas data. Finally, knockdown of syntenin-1 inhibited the proliferation, migration and invasion of HNSC cells, and opposite findings were observed when syntenin-1 was over-expressed. Collectively, our studies indicate that syntenin-1 promotes invasion and progression of HNSC. It may serve as a valuable biomarker for lymph node metastasis or a potential target for therapeutic intervention in HNSC.

Cancer Med 2018; 7:809-819. [PMID: 29441725 PMCID: PMC5852339 DOI: 10.1002/cam4.1325] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Revised: 12/12/2017] [Accepted: 12/13/2017] [Indexed: 12/14/2022] Open
Abstract
Cancer cell invasion and unlimited proliferation are key factors in patients with colorectal cancer (CRC). Increased protein deglycase DJ-1 in cancer cells is known to promote tumor growth; however, its role in CRC progression is not well defined. In this study, we investigated 100 CRC patients with disease stages I-IV to determine whether DJ-1 could serve as a prognostic biomarker in CRC. These results showed that DJ-1 expression in CRC tissues was higher than that in normal colon tissues and was associated with the (Tumor Node Metastasis) TNM stage. CRC patients with low DJ-1 expression had a longer overall survival than those with high expression, and multivariate and univariate analyses indicated that DJ-1 expression was an independent prognostic factor for overall survival in CRC. Furthermore, DJ-1 overexpression in two colon cancer cell lines, HCT116 and SW480, activated protein kinase AKT and downregulated tumor suppressor PTEN, whereas DJ-1 knockdown upregulated PTEN expression and effectively suppressed CRC cell invasion and proliferation both in vitro and in vivo, revealing a mechanism underlying DJ-1 pro-oncogenic activity in CRC. Treatment of MK2206, the specific AKT inhibitor, significantly decreased DJ-1-mediated cell proliferation and mobility in vitro. Taken together, these results suggest that DJ-1 may be a novel prognostic biomarker and potential therapeutic target in human CRC.

Abstract
Deregulated expression of SOX11 has been shown to be involved in the progression of various types of cancer. However, the role of SOX11 in head and neck cancer remains largely unknown. In this study, coimmunoprecipitation (Co-IP) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were performed to identify the proteins that bind to SOX11 at significantly higher levels in head and neck cancer cells than in normal human oral keratinocytes. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses indicated that many potential SOX11-binding partners were associated with protein synthesis, cell metabolism, and cell-cell adhesion. One of the identified proteins, heat shock protein 90 alpha (HSP90α), was selected for further investigation. The binding of HSP90α with SOX11 in head and neck cancer cells was validated by Co-IP with western blotting. In addition, HSP90α was found to be remarkably overexpressed in head and neck cancer cell lines when compared to its level in normal human oral keratinocytes, and knockdown of HSP90α inhibited the proliferation and invasion capacity of these cancer cells. On the basis of The Cancer Genome Atlas (TCGA) data analysis, HSP90AA1 gene was overexpressed in head and neck cancer tissues compared to normal controls and increased HSP90AA1 gene expression was positively associated with extracapsular spread and clinical stage. Head and neck cancer patients with higher HSP90AA1 expression had significantly poorer long-term overall and disease-free survival rates than those with lower HSP90AA1 expression. Collectively, our studies indicate that SOX11 binds to HSP90α, a highly overexpressed protein that may promote invasion and progression of head and neck cancer cells.

Abstract
Circulating microRNAs (miRNAs) have been demonstrated to be potential biomarkers in various cancers including head and neck squamous cell carcinoma (HNSCC). The aim of this study was to assess the diagnostic and prognostic significance of serum miR-138 in HNSCC. Quantitative reverse-transcription PCR (qRT-PCR) was used to measure serum miR-138 levels in 113 HNSCC cases and 60 controls. The results showed that serum miR-138 expression was remarkably down-regulated in HNSCC patients compared to healthy volunteers. Moreover, serum miR-138 levels in 32 patients after receiving surgical treatment were significantly increased. Also, the receiver operating characteristic (ROC) curve analysis revealed that serum miR-138 could discriminate HNSCC patients from controls with high accuracy. Furthermore, a positive correlation was observed between decreased serum miR-138 and worse clinical outcome, as well as shorter survival. Then serum miR-138 was confirmed to be an independent prognostic indicator for HNSCC. Our results demonstrated that serum miR-138 might be a potential biomarker for detection and prognosis prediction of HNSCC.

Abstract
BACKGROUND The non-invasive diagnostic approach for early detection of endometrial cancer (EC) remains limited. To date, human epididymis protein 4 (HE4) has been intensively studied but its diagnostic is controversial in EC. DJ-1 is an oncoprotein secreted by cancer cells, recently identified as a potential diagnostic biomarker for breast cancer, melanoma, and pancreatic cancer. The aim of this study was to compare the diagnostic performances of DJ-1 and HE4 measured in EC patients and healthy controls (HC). METHODS Forty-five patients (63.9±12.0 years) with EC and 29 (63.2±13.3 years) HC were enrolled. Serum concentrations of DJ-1 and HE4 were measured using ELISA kits developed by R&D (Minneapolis, USA) and Fujirebio Diagnostic (Malvern, PA, USA), respectively. Differences between EC patients and HC were assessed by Mann-Whitney test and associations were tested by Spearman's correlation. The diagnostic performance was assessed using receiver operating characteristics (ROC) curves analysis. RESULTS Serum DJ-1 concentrations were found to be higher in EC patients than in HC (9533.6 vs 1988.5 pg/mL; P<.0001). The area under the ROC curve (ROC-AUC) was 0.95 (P<.0001). At the cut-off of 3654 pg/mL, the sensitivity and specificity were 0.89 and 0.90, respectively. HE4 serum levels were higher in EC patients than in HC (75.3 vs 56.2 pmol/L; P=.019), with an AUC of 0.66 (P=.020). The AUC obtained by the combination of the two markers resulted 0.96 (P<.0001). CONCLUSION These results suggest that increased serum DJ-1 levels are associated with EC and that this biomarker may be potentially useful for diagnosing EC.
