Objective: To investigate the influence of Notch signaling on osteoprotegerin(OPG)expression in a human oral squamous cell carcinoma cell line.Methods: Activation of Notch signaling was performed by seeding cells on Jagged1 immobilized surfaces. In other experiments, a g-secretase inhibitor was added to the culture medium to inhibit intracellular Notch signaling. OPG m RNA and protein were determined by real-time PCR and ELISA, respectively. Finally, publicly available microarray database analysis was performed using connection up- or down-regulation expression analysis of microarrays software.Results: Jagged1-treatment of HSC-4 cells enhanced HES1 and HEY1 m RNA expression, confirming the intracellular activation of Notch signaling. OPG m RNA and protein levels were significantly suppressed upon Jagged1 treatment. Correspondingly, HSC-4 cells treated with a g-secretase inhibitor resulted in a significant reduction of HES1 and HEY1 m RNA levels, and a marked increase in OPG protein expression was observed.These results implied that Notch signaling regulated OPG expression in HSC-4 cells.However, Jagged1 did not alter OPG expression in another human oral squamous cell carcinoma cell line(HSC-5) or a human head and neck squamous cell carcinoma cell line(HN22).Conclusions: Notch signaling regulated OPG expression in an HSC-4 cell line and this mechanism could be cell line specific. 展开更多

Oral squamous cell carcinoma(OSCC)is one of the most prevalent forms of head and neck squamous cell carcinomas(HNSCC)with a poor overall survival rate(about 50%),particularly in cases of metastasis.RNA-based cancer biomarkers are a relatively advanced concept,and non-coding RNAs currently have shown promising roles in the detection and treatment of various malignancies.This review underlines the function of long non-coding RNAs(lncRNAs)in the OSCC and its subsequent clinical implications.LncRNAs,a class of non-coding RNAs,are larger than 200 nucleotides and resemble mRNA in numerous ways.However,unlike mRNA,lncRNA regulates multiple druggable and non-druggable signaling molecules through simultaneous interaction with DNA,RNA,proteins,or microRNAs depending on concentration and localization in cells.Upregulation of oncogenic lncRNAs and downregulation of tumor suppressor lncRNAs are evident in OSCC tissues and body fluids such as blood and saliva indicating their potential as valuable biomarkers.Targeted inhibition of candidate oncogenic lncRNAs or overexpression of tumor suppressor lncRNAs showed potential therapeutic roles in in-vivo animal models.The types of lncRNAs that are expressed differentially in OSCC tissue and bodily fluids have been systematically documented with specificity and sensitivity.This review thoroughly discusses the biological functions of such lncRNAs in OSCC cell survival,proliferation,invasion,migration,metastasis,angiogenesis,metabolism,epigenetic modification,tumor immune microenvironment,and drug resistance.Subsequently,we addressed the diagnostic and therapeutic importance of lncRNAs in OSCC pre-clinical and clinical systems,providing details on ongoing research and outlining potential future directions for advancements in this field.In essence,this review could be a valuable resource by offering comprehensive and current insights into lncRNAs in OSCC for researchers in fundamental and clinical domains. 展开更多

BACKGROUND Immunochemotherapy involving the combination of programmed cell death 1/programmed cell death ligand 1 inhibitors with chemotherapy has advanced the treatment of locally advanced esophageal squamous cell carcinoma(ESCC).The use of corticosteroids as pretreatment might reduce immunotherapy efficacy.AIM To investigate the impact of baseline corticosteroid use on neoadjuvant immunochemotherapy(nIC)outcomes in locally advanced ESCC patients.METHODS Patients with locally advanced ESCC who received nIC at Sun Yat-sen University Cancer Center and the Third Affiliated Hospital of Sun Yat-sen University were included.Patients were divided into dexamethasone and antihistamine groups on the basis of the administered pretreatment.Antiallergic efficacy and safety were evaluated,as well as its impact on short-term efficacy[complete pathological response(pCR),major pathological response(MPR)]and long-term efficacy[overall survival(OS),progression-free survival(PFS)]of nIC.RESULTS From September 2019 to September 2023,142 patients were analyzed.No severe treatment-related adverse events or deaths were observed.Allergy occurrence was greater in the antihistamine group(P=0.014).Short-term efficacy was not significantly different:The pCR rates were 29.9%and 40.0%,and the MPR rates were 57.9%and 65.7%in the dexamethasone and antihistamine groups,respectively.The long-term efficacy was not significantly different:The 2 years OS rates were 95.2%and 93.5%,and the 2 years PFS rates were 90.3%and 87.8%.Subgroup analysis revealed no difference in OS between the 20 mg dexamethasone group and the<20 mg dexamethasone group,but PFS was significantly greater in the 20 mg dexamethasone group(93.9%vs 56.4%,P=0.001).CONCLUSION Dexamethasone or antihistamines can be used before nIC in locally advanced ESCC without affecting short-or long-term efficacy.Administering 20 mg dexamethasone before nIC may improve PFS in ESCC. 展开更多

Background:Galectin 2(LGALS2)is a protein previously reported to serve as a mediator of disease progression in a range of cancers.The function of LGALS2 in oral squamous cell carcinoma(OSCC),however,has yet to be explored,prompting the present study to address this literature gap.Methods:Overall,144 paired malignant tumor tissues and paracancerous OSCC patient samples were harvested and the LGALS2 expression levels were examined through qPCR and western immunoblotting.The LGALS2 coding sequence was introduced into the pcDNA3.0 vector,to enable the overexpression of this gene,while an LGALS2-specific shRNA and corresponding controls were also obtained.The functionality of LGALS2 as a regulator of the ability of OSCC cells to grow and undergo apoptotic death in vitro was assessed through EdU uptake and CCK-8 assays,and flow cytometer,whereas a Transwell system was used to assess migratory activity and invasivity.An agonist of the Janus Kinase 2(JAK2)/Signal Transducer and Activator of Transcription 3(STAT3)pathway was also used to assess the role of this pathway in the context of LGALS2 signaling.Results:Here,we found that lower LGALS2 protein and mRNA expression were evident in OSCC tumor tissue samples,and these expression levels were associated with clinicopathological characteristics and patient survival outcomes.Silencing LGALS2 enhanced proliferation in OSCC cells while rendering these cells better able to resist apoptosis.The opposite was instead observed after LGALS2 was overexpressed.Mechanistically,the ability of LGALS2 to suppress the progression of OSCC was related to its ability to activate the JAK/STAT3 signaling axis.Conclusion:Those results suggest a role for LGALS2 as a suppressor of OSCC progression through its ability to modulate JAK/STAT3 signaling,supporting the potential utility of LGALS2 as a target for efforts aimed at treating OSCC patients. 展开更多

Background:Oral squamous cell carcinoma(OSCC)represents a prevalent malignancy in the oral and maxillofacial area,having a considerable negative impact on both the quality of life and overall survival of affected individuals.Our research endeavors to leverage bioinformatic approaches to elucidate oncogenic signaling pathways,with the ultimate goal of gaining deeper insights into the molecular underpinnings of OSCC pathogenesis,and thus laying the groundwork for the development of more effective therapeutic and preventive strategies.Methods:Differential expression analysis was performed on mRNA data from tumor and normal tissue groups to identify genes associated with OSCC,using The Cancer Genome Atlas database.Predictions of oncogenic signaling pathways linked to differentially expressedmRNAs were made,and these results were presented visually using R software,using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichments.Results:GO and KEGG analyses of 2938 differentially expressed genes in OSCC highlighted their significant involvement in various biological processes.Notably,these processes were related to the extracellular matrix,structural organization,connective tissue development,and cell cycle regulation.Conclusions:The comprehensive exploration of gene expression patterns provides valuable insights into potential oncogenic mechanisms in OSCC. 展开更多

Esophageal squamous cell carcinoma(ESCC)is a substantial global health burden.Immune escape mechanisms are important in ESCC progression,enabling cancer cells to escape the surveillance of the host immune system.One key player in this process is the Aryl Hydrocarbon Receptor(AhR),which influences multiple cellular processes,including proliferation,differentiation,metabolism,and immune regulation.Dysregulated AhR signaling participates in ESCC development by stimulating carcinogenesis,epithelial-mesenchymal transition,and immune escape.Targeting AhR signaling is a potential therapeutic approach for ESCC,with AhR ligands showing efficacy in preclinical studies.Additionally,modification of AhR ligands and combination therapies present new opportunities for therapeutic intervention.This review aims to address the knowledge gap related to the role of AhR signaling in ESCC pathogenesis and immune escape. 展开更多

Objective:CD8+T cells are the key effector cells in the anti-tumor immune response.The mechanism underlying the infiltration of CD8+T cells in esophageal squamous cell carcinoma(ESCC)has not been clearly elucidated.Methods:Fresh ESCC tissues were collected and grouped according to the infiltration density of CD8+T cells.After the transcriptome sequencing on these samples and the combined analyses with The Cancer Genome Atlas(TCGA)ESCC data,a secreted protein DEFB1 was selected to explore its potential role in the infiltration of CD8+T cells.Bioinformatics analyses,histological verification and in vitro experiments were then performed.Results:DEFB1 was highly expressed in ESCC,and the high expression of DEFB1 was an independent risk factor for overall survival.Since the up-regulation or down-regulation of DEFB1 did not affect the proliferation,migration and apoptosis of ESCC cells,we speculated that the oncogenic effect of DEFB1 was achieved by regulating microenvironmental characteristics.Bioinformatics analyses suggested that DEFB1 might play a major role in the inflammatory response and anti-tumor immune response,and correlate to the infiltration of immature dendritic cell(imDC)in ESCC.Histological analyses further confirmed that there were less CD8+T cells infiltrated,less CD83+mature DC(mDC)infiltrated and more CD1a+imDC infiltrated in those ESCC samples with high expression of DEFB1.After the treatment with recombinant DEFB1 protein,the maturation of DC was hindered significantly,followed by the impairment of the killing effects of T cells in both 2D and 3D culture in vitro.Conclusions:Tumor-derived DEFB1 can inhibit the maturation of DC and weaken the function of CD8+T cells,accounting for the immune tolerance in ESCC.The role of DEFB1 in ESCC deserves further exploration. 展开更多

Background:The role of Claudin-1 in tongue squamous cell carcinoma(TSCC)metastasis needs further clarification,particularly its impact on cell migration.Herein,our study aims to investigate the role of Claudin-1 in TSCC cell migration and its underlying mechanisms.Methods:36 TSCC tissue samples underwent immunohistochemical staining for Claudin-1.Western blotting and immunofluorescence analyses were conducted to evaluate Claudin-1 expression and distribution in TSCC cells.Claudin-1 knockdown cell lines were established using short hairpin RNA transfection.Migration effects were assessed through wound healing assays.Furthermore,the expression of EMTassociated molecules was measured via western blotting.Results:Claudin-1 expression decreased as TSCC malignancy increased.Adenosine monophosphate–activated protein kinase(AMPK)activation led to increased Claudin-1 expression and membrane translocation,inhibiting TSCC cell migration and epithelial–mesenchymal transition(EMT).Conversely,Claudin-1 knockdown reversed these inhibitory effects on migration and EMT caused by AMPK activation.Conclusions:Our results indicated that AMPK activation suppresses TSCC cell migration by targeting Claudin-1 and EMT pathways. 展开更多

As a highly invasive carcinoma,esophageal cancer(EC)was the eighth most prevalent malignancy and the sixth leading cause of cancer-related death worldwide in 2020.Esophageal squamous cell carcinoma(ESCC)is the major histological subtype of EC,and its incidence and mortality rates are decreasing globally.Due to the lack of specific early symptoms,ESCC patients are usually diagnosed with advanced-stage disease with a poor prognosis,and the incidence and mortality rates are still high in many countries,especially in China.Therefore,enormous challenges still exist in the management of ESCC,and novel strategies are urgently needed to further decrease the incidence and mortality rates of ESCC.Although the key molecular mechanisms underlying ESCC pathogenesis have not been fully elucidated,certain promising biomarkers are being investigated to facilitate clinical decision-making.With the advent and advancement of highthroughput technologies,such as genomics,proteomics and metabolomics,valuable biomarkers with high sensitivity,specificity and stability could be identified for ESCC.Herein,we aimed to determine the epidemiological features of ESCC in different regions of the world,especially in China,and focused on novel molecular biomarkers associated with ESCC screening,early diagnosis and prognosis prediction. 展开更多

Antibody-drug conjugates(ADCs)are a new type of targeting antibodies that conjugate with highly toxic anticancer drugs via chemical linkers to exert high specificity and efficient killing of tumor cells,thereby attracting considerable attention in precise oncology therapy.Cetuximab(Cet)is a typical antibody that offers the benefits of good targeting and safety for individuals with advanced and inoperable cutaneous squamous cell carcinoma(cSCC);however,its anti-tumor activity is limited to a single use.Cisplatin(CisPt)shows good curative effects;however,its adverse effects and non-tumor-targeting ability are major drawbacks.In this study,we designed and developed a new ADC based on a new cytotoxic platinum(IV)prodrug(C8Pt(IV))and Cet.The so-called antibody-platinum(IV)prodrugs conjugates,named Cet-C8Pt(IV),showed excellent tumor targeting in cSCC.Specifically,it accurately delivered C8Pt(IV)into tumor cells to exert the combined anti-tumor effect of Cet and CisPt.Herein,metabolomic analysis showed that Cet-C8Pt(IV)promoted cellular apoptosis and increased DNA damage in cSCC cells by affecting the vitamin B6 metabolic pathway in tumor cells,thereby further enhancing the tumor-killing ability and providing a new strategy for clinical cancer treatment using antibody-platinum(IV)prodrugs conjugates. 展开更多

BACKGROUND Esophageal squamous cell carcinoma(ESCC)is a deadly malignancy with limited treatment options.Deubiquitinases(DUBs)have been confirmed to play a crucial role in the development of malignant tumors.JOSD2 is a DUB involved in con-trolling protein deubiquitination and influencing critical cellular processes in cancer.AIM To investigate the impact of JOSD2 on the progression of ESCC.METHODS Bioinformatic analyses were employed to explore the expression,prognosis,and enriched pathways associated with JOSD2 in ESCC.Lentiviral transduction was utilized to manipulate JOSD2 expression in ESCC cell lines(KYSE30 and RESULTS )Preliminary research indicated that JOSD2 was highly expressed in ESCC tissues,which was associated with poor prognosis.Further analysis demonstrated that JOSD2 was upregulated in ESCC cell lines compared to normal esophageal cells.JOSD2 knockdown inhibited ESCC cell activity,including proliferation and colony-forming ability.Moreover,JOSD2 knockdown decreased the drug resistance and migration of ESCC cells,while JOSD2 overexpression enhanced these phenotypes.In vivo xenograft assays further confirmed that JOSD2 promoted tumor proliferation and drug resistance in ESCC.Mechanistically,JOSD2 appears to activate the MAPK/ERK and PI3K/AKT signaling pathways.Mass spectrometry was used to identify crucial substrate proteins that interact with JOSD2,which identified the four primary proteins that bind to JOSD2,namely USP47,IGKV2D-29,HSP90AB1,and PRMT5.CONCLUSION JOSD2 plays a crucial role in enhancing the proliferation,migration,and drug resistance of ESCC,suggesting that JOSD2 is a potential therapeutic target in ESCC. 展开更多

Esophageal squamous cell carcinoma(ESCC)is a malignant epithelial tumor,characterized by squamous cell differentiation,it is the sixth leading cause of cancer-related deaths globally.The increased mortality rate of ESCC patients is predominantly due to the advanced stage of the disease when discovered,coupled with higher risk of metastasis,which is an exceedingly malignant charac-teristic of cancer,frequently leading to a high mortality rate.Unfortunately,there is currently no specific and effective marker to predict and treat metastasis in ESCC.MicroRNAs(miRNAs)are a class of small non-coding RNA molecules,approximately 22 nucleotides in length.miRNAs are vital in modulating gene expression and serve pivotal regulatory roles in the occurrence,progression,and prognosis of cancer.Here,we have examined the literature to highlight the intimate correlations between miRNAs and ESCC metastasis,and show that ESCC metastasis is predominantly regulated or regulated by genetic and epigenetic factors.This review proposes a potential role for miRNAs as diagnostic and therapeutic biomarkers for metastasis in ESCC metastasis,with the ultimate aim of reducing the mortality rate among patients with ESCC. 展开更多

Objective:Lung squamous cell carcinoma(LUSC)is associated with a low survival rate.Evidence suggests that bone morphogenetic proteins(BMPs)and their receptors(BMPRs)play crucial roles in tumorigenesis and progression.However,a comprehensive analysis of their role in LUSC is lacking.Our study aimed to explore the relationship between BMPs/BMPRs expression levels and the tumorigenesis and prognosis of LUSC.Methods:The“R/Limma”package was utilized to analyze the differential expression characteristics of BMPs/BMPRs in LUSC,using data from TCGA,GTEx,and GEO databases.Concurrently,the“survminer”packages were employed to investigate their prognostic value and correlation with clinical features in LUSC.The core gene associated with LUSC progression was further explored through weighted gene correlation network analysis(WGCNA).LASSO analysis was conducted to construct a prognostic risk model for LUSC.Clinical specimens were examined by immunohistochemical analysis to confirm the diagnostic value in LUSC.Furthermore,based on the tumor immune estimation resource database and tumor-immune system interaction database,the role of the core gene in the tumor microenvironment of LUSC was explored.Results:GDF10 had a significant correlation only with the pathological T stage of LUSC,and the protein expression level of GDF10 decreased with the tumorigenesis of LUSC.A prognostic risk model was constructed with GDF10 as the core gene and 5 hub genes(HRASLS,HIST1H2BH,FLRT3,CHEK2,and ALPL)for LUSC.GDF10 showed a significant positive correlation with immune cell infiltration and immune checkpoint expression.Conclusion:GDF10 might serve as a diagnostic biomarker reflecting the tumorigenesis of LUSC and regulating the tumor immune microenvironment to guide more effective treatment for LUSC. 展开更多

Background:Fibroblast activation protein(FAP),a cell surface serine protease,plays roles in tumor invasion and immune regulation.However,there is currently no pan-cancer analysis of FAP.Objective:We aimed to assess the pan-cancer expression profile of FAP,its molecular function,and its potential role in head and neck squamous cell carcinoma(HNSC).Methods:We analyzed gene expression,survival status,immune infiltration,and molecular functional pathways of FAP in The Cancer Genome Atlas(TCGA)and Genotype Tissue Expression(GTEx)tumors.Furthermore,to elucidate the role of FAP in HNSC,we performed proliferation,migration,and invasion assays post-FAP overexpression or knock-down.Results:FAP expression was elevated in nine tumor types and was associated with poor survival in eight of them.In the context of immune infiltration,FAP expression negatively correlated with CD8+T-cell infiltration infive tumor types and positively with regulatory T-cell infiltration in four tumor types.Our enrichment analysis highlighted FAP’s involvement in the PI3K-Akt signaling pathway.In HNSC cells,FAP overexpression activated the PI3K-Akt pathway,promoting tumor proliferation,migration,and invasion.Conversely,FAP knockdown showed inhibitory effects.Conclusion:Our study unveils the association of FAP with poor tumor prognosis across multiple cancers and highlights its potential as a therapeutic target in HNSC. 展开更多

Objective:To investigate the effect of MMP-9 inhibitor(Mki67)on the biology of human oral squamous cell carcinoma SCC15 cell line and to explore its mechanism of action through PI3K/Akt signaling pathway.Methods:SCC15 cells were extracted,and the supernatant was discarded.The cells were then rinsed twice with PBS,and 0,2.5,5,and 10μL of Mki67(50 mg/mL)were added to the culture respectively.The inhibition rate of cell proliferation was detected by 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide(MTT)method,and the cell migration was measured by Transwell chamber test.The cell apoptosis rate was detected by cytometry,and the p-Akt protein content in the cells of each group was determined by a double-antibody sandwich enzyme-linked immunosorbent assay(ELISA)kit.Results:The cell proliferation rates of the 2.5μL,5μL,and 10μL dose groups were all lower than the 0μL group(P<0.05)before treatment,and the cell proliferation rates in the 2.5μL,5μL,and 10μL dose groups decreased overtime(P<0.05).After 24 h,with the increase of Mki67 concentration,the number of migration and invasion gradually decreased(P<0.05),and the number of apoptosis gradually increased(P<0.05);besides,the relative expression of MMP-9,PI3K,and Akt mRNA decreased gradually(P<0.05),and the expression level of Akt mRNA was not statistically significant(P>0.05).Conclusion:MMP-9 inhibitor(Mki67)can inhibit the proliferation and migration of SCC15 cell line and induce apoptosis,and its mechanism of action may be related to the inhibition of PI3K/Akt signaling pathway. 展开更多

In this editorial,we comment on the article by Wang et al published in the recent issue of the World Journal of Gastroenterology in 2023.We focused on identifying risk factors for lymph node metastasis(LNM)in superficial esophageal squamous cell carcinoma(SESCC)patients and how to construct a simple and reliable clinical prediction model to assess the risk of LNM in SESCC patients,thereby helping to guide the selection of an appropriate treatment plan.The current standard treatment for SESCC is radical esophagectomy with lymph node dissection.However,esophagectomy is associated with considerable morbidity and mortality.Endoscopic resection(ER)offers a safer and less invasive alternative to surgical resection and can enable the patient's quality of life to be maintained while providing a satisfactory outcome.However,since ER is a localized treatment that does not allow for lymph node dissection,the risk of LNM in SESCC limits the effectiveness of ER.Understanding LNM status can aid in determining whether patients with SESCC can be cured by ER without the need for additional esophagectomy.Previous studies have shown that tumor size,macroscopic type of tumor,degree of differentiation,depth of tumor invasion,and lymphovascular invasion are factors associated with LNM in patients with SESCC.In addition,tumor budding is commonly associated with LNM,recurrence,and distant metastasis,but this topic has been less covered in previous studies.By comprehensively evaluating the above risk factors for LNM,useful evidence can be obtained for doctors to select appropriate treatments for SESCC patients. 展开更多

In recent years,endoscopic resection,particularly endoscopic submucosal dis-section,has become increasingly popular in treating non-metastatic superficial esophageal squamous cell carcinoma(ESCC).In this evolving paradigm,it is crucial to identify factors that predict higher rates of lymphatic invasion and poorer outcomes.Larger tumor size,deeper invasion,poorer differentiation,more infiltrative growth patterns(INF-c),higher-grade tumor budding,positive lymphovascular invasion,and certain biomarkers have been associated with lymph node metastasis and increased morbidity through retrospective reviews,leading to the construction of comprehensive nomograms for outcome prediction.If validated by future prospective studies,these nomograms would prove highly applicable in guiding the selection of treatment for superficial ESCC. 展开更多
