Abstract
Head and neck cancer (HNC) represents a significant global health challenge, with squamous cell carcinomas (SCCs) accounting for approximately 90% of all HNC cases. These malignancies, collectively referred to as head and neck squamous cell carcinoma (HNSCC), originate from the mucosal epithelium lining the larynx, pharynx, and oral cavity. The primary risk factors associated with HNSCC in economically disadvantaged nations have been chronic alcohol consumption and tobacco use. However, in more affluent countries, the landscape of HNSCC has shifted with the identification of human papillomavirus (HPV) infection, particularly HPV-16, as a major risk factor, especially among nonsmokers. Understanding the evolving risk factors and the distinct biological behaviors of HPV-positive and HPV-negative HNSCC is critical for developing targeted treatment strategies and improving patient outcomes in this complex and diverse group of cancers. Accurate diagnosis of HPV-positive HNSCC is essential for developing a comprehensive model that integrates the molecular characteristics, immune microenvironment, and clinical outcomes. The aim of this comprehensive review was to summarize the current knowledge and advances in the identification of DNA, RNA, and protein biomarkers in bodily fluids and tissues that have introduced new possibilities for minimally or non-invasive cancer diagnosis, monitoring, and assessment of therapeutic responses.

[PMID: 38845955 PMCID: PMC11154600 DOI: 10.1016/j.heliyon.2024.e31969] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 05/21/2024] [Accepted: 05/24/2024] [Indexed: 06/09/2024] Open
Abstract
Objective Circular RNAs (circRNAs) significantly influence the invasion, metastasis, gene expression, proliferation, and apoptosis of tumor cells. However, the roles of circRNAs in laryngeal squamous cell carcinoma (LSCC) remain largely unexplored. This study aims to examine circRNA expression patterns in LSCC and adjacent non-tumorous tissues, with the goal of uncovering potential biomarkers for LSCC. Methods Tissue samples were collected from both the tumor and adjacent normal tissues of ten patients who had undergone surgical resection. The profiling of circRNAs was conducted through transcriptomic sequencing and analytical bioinformatics approaches. A ternary regulatory network based on the competitive endogenous RNA (ceRNA) hypothesis was established, linking target circRNAs to clinical immunohistochemical parameters for comparison. Verification of target circRNAs in LSCC tissues was performed using quantitative real-time PCR (RT-qPCR), whereas target mRNAs were analyzed through immunohistochemistry. Results A total of 126 significantly different circRNAs were identified, including 40 up-regulated genes and 86 down-regulated genes. Furthermore, 92 circRNA-miRNA-mRNA regulatory relationship axes related to clinical immunohistochemical indicators were found based on 5 candidate circRNAs. Interestingly, all axes related to the target genes MKI67 and TP53 were found to compete with the same circRNA: hsa_circ_0069,399. Further verification confirmed that the hsa_circ_0069,399 expression was overtly upregulated in tumor tissues from LSCC patients, which was consistent with the sequencing results. Conclusion hsa_circ_0069,399 could be a potential prognostic marker for LSCC.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2024; 125:101806. [PMID: 38408642 DOI: 10.1016/j.jormas.2024.101806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Revised: 02/22/2024] [Accepted: 02/23/2024] [Indexed: 02/28/2024]
Abstract
OBJECTIVES Oral squamous cell carcinoma (OSCC) is the most common type of oral neoplasms that consist of more over 90% of oral cancers. It was demonstrated that erosive atrophic oral lichen planus (OLP) has potential of malignancy transformation into OSCC. The microRNAs are non-coding regulator sequences involved in cancer process. The miR-99a involve in growth, proliferation, migration, invasion, and metastasis of tumor cells. Therefore, we evaluated miR-99a expression in serum of OSCC and erosive atrophic OLP patients in comparison to healthy control individuals to more investigate about level of miR-99a expression in potential premalignant disorder (erosive atrophic OLP) in comparison to malignant transformation form (OSCC). Gene ontology (GO) and pathway analyses were performed to better understand the importance of miR-99a in OSCC. MATERIALS AND METHODS In this cross-sectional study, total 90 serum samples from OSCC patients (n = 30), erosive atrophic OLP (n = 30) and healthy control individuals (n = 30) were collected, and then evaluated for miR-99a expression by qPCR. Pathway analysis and protein-protein interaction were done using STRING (v: 12.0), and (GO) terms and related genes were extracted from the GO online search tool. The statistical analysis was evaluated by Kruskal Wallis, Chi-Square, Kruskal Wallis, Spearman and Mann-Whitney tests. The p-value less than 0.05 was considered statistically significant. RESULTS miR-99a expression down regulated in OSCC in comparison to erosive atrophic OLP and control groups (p < 0.05). The miR-99a up regulated in grade I more than grades II and III (p < 0.05). We showed upregulation of miR-99a in early stage more than advanced stage (p < 0.05). Expression of miR-99a reduced accordance to the increasing of tumor size and lymph involvement levels (p < 0.05). The 165 determined targets were classified into three domains. The most significant enrichment in biological processes, cellular components, and molecular functions was in the cellular nitrogen compound biosynthetic process, cytosolic ribosome, and protein binding, respectively. CONCLUSIONS We highlighted tumor suppressive role of miR-99a in OSCC patients. It seems that miR-99a can be considered a valuable biomarker for the early diagnosis of erosive atrophic OLP before transformation. CLINICAL RELEVANCE Our results may help to better understand the prognostic factor for oral squamous cell carcinoma to evaluate survival and subsequent tumor development. And it may also help to understand the pathogenesis of OSCC.

Prediction of network pharmacology, molecular docking-based strategy, and vitro assays to determine potential pharmacological mechanism of Dioscoreae bulbiferae and Bruceae fructus against laryngocarcinoma. Medicine (Baltimore) 2023; 102:e36771. [PMID: 38134081 PMCID: PMC10735085 DOI: 10.1097/md.0000000000036771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 12/01/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND Based on network pharmacology, molecular docking, and vitro assays, investigate the probable pharmacological mechanism of Dioscoreae bulbiferae and Bruceae fructus in the treatment of laryngocarcinoma. METHODS The active components and targets of Dioscoreae bulbiferae and Bruceae fructus were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform database. Targets linked with laryngocarcinoma were gathered from the GeneCards, DisGeNET, and DrugBank databases. The String database was utilized to build a protein-protein interaction network of common medication and illness targets, after which the core targets were filtered out. The Metascape database served for gene ontology enrichment and Kyoto encyclopedia of genes and genomes pathway analysis of common targets. AutoDock then performed molecular docking between the essential component and the vital target. To investigate the biological effects of diosbulbin B, we assessed the viability of laryngocarcinoma cells after diosbulbin B therapy using the Mahalanobis Taguchi system technique. Following that, we looked at how diosbulbin B affected colony formation after 14 days of culture of treated cells. Flow cytometry was utilized to detect apoptosis in order to examine the influence of diosbulbin B on laryngocarcinoma cell apoptosis. RESULTS According to a study of the literature, the fundamental components of Dioscoreae bulbiferae and Bruceae fructus in the treatment of laryngocarcinoma include brusatol and diosbulbin B, which may operate on core targets such as cyclin D1, Cyclin Dependent Kinase Inhibitor 1A, and E2F Transcription Factor 1. The significant pathways discovered using Kyoto encyclopedia of genes and genomes enrichment analysis were the phosphoinositide 3-kinase-protein kinase B signaling route, the tumor necrosis factor signaling pathway, and so on. These pathways primarily influence the development and prognosis of laryngeal cancer by controlling cell growth, cell proliferation, angiogenesis, tumorigenesis, and metastasis. The molecular docking studies revealed that the affinity between the heart and crucial targets was robust. The results of vitro assays indicate that diosbulbin B suppressed Hep-2 cell activity in a concentration-dependent manner. Besides, diosbulbin B has powerful antiproliferative properties in Hep-2 cells. Flow cytometry results showed that diosbulbin B promoted laryngocarcinoma cell apoptosis in a concentration-dependent manner. CONCLUSION The article delivered a preliminary discussion of the probable mechanism of Dioscoreae bulbiferae and Bruceae fructus in the treatment of laryngocarcinoma, which can serve as a theoretical basis and evidence for subsequent experimental investigation.

Abstract
OBJECTIVE To explore the effect of personalized nursing on the therapeutic effect on patients with laryngeal squamous cell carcinoma (LSCC) combined with Helicobacter pylori (HP) infection after surgery. METHODS This study enrolled 46 patients with LSCC as research subjects. The patients were divided into an experimental group and a control group using the random number table method. Routine nursing was provided in the control group, and individualized nursing intervention was conducted in the experimental group based on routine nursing. The incidence of adverse reactions (ARs) and the patients' nursing satisfaction were compared between the two groups. RESULTS Compared with the control group, the individualized nursing intervention reduced the incidence of ARs of esophageal reflux (P < 0.05) and improved nursing satisfaction (P < 0.05). CONCLUSION Individualized nursing intervention reduced the incidence of esophageal reflux ARs in patients with LSCC and HP infection after tracheotomy and improved both the therapeutic effect of the treatment and the satisfaction of the patients.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth most prevalent malignancy worldwide. Accumulating evidence suggests that persistent HPV infection is closely related to a subset of HNSCC types, and the incidence of human papillomavirus (HPV)-positive HNSCC has been annually increasing in recent decades. Although the carcinogenesis of HPV-positive HNSCC has not been completely elucidated, it has been well confirmed that E6 and E7, the main viral oncoproteins are responsible for the maintenance of malignant transformation, promotion of cell proliferation, and increase in tumor invasion. Moreover, compared with HPV-negative HNSCC, HPV-positive HNSCC shows some special clinical-pathological features, which are possibly related to HPV infection and their specific regulatory mechanisms. Non-coding RNA (ncRNA) is a class of RNA lacking the protein-coding function and playing a critical regulatory role via multiple complex molecular mechanisms. NcRNA is an important regulatory pattern of epigenetic modification, which can exert significant effects on HPV-induced tumorigenesis and progression by deregulating downstream genes. However, the knowledge of ncRNAs is still limited, hence, a better understanding of ncRNAs could provide some insights for exploring the carcinogenesis mechanism and identifying valuable biomarkers in HPV-positive HNSCC. Therefore, in this review, we mainly focused on the expression profile of ncRNAs (including lncRNA, miRNA, and circRNA) and explored their regulatory role in HPV-positive HNSCC, aiming to clarify the regulatory mechanism of ncRNAs and identify valuable biomarkers for HPV-positive HNSCC.

Abstract
Background and objective The tumor's microenvironment is currently considered an important indicator of the tumor's prognosis, treatment failure, and recurrence. CD163+ tumor-associated macrophages (TAMs) are a marker of poor prognosis in many types of human cancers. In the present study, the expression of CD163+ TAMs was analyzed in laryngeal squamous cell carcinomas (LSCCs) using immunohistochemistry, and this expression was correlated with the clinical and pathological characteristics of LSCC patients. Materials and methods One commercial human larynx microarray with 80 cases of LSCCs, was used for this study. For comparison with normal laryngeal mucosa, a second microarray carrying normal tissues from all human anatomical sites, including normal laryngeal tissues, was used. Immunohistochemical staining was performed, and the primary antibody was a mouse monoclonal against human CD136. The absence of the primary antibody was used as a negative control. The percentage of positive cells was categorized into five scores: 0 (0%); 1, (1%-10%); 2, (11%-50%); 3, (51%-80%); and 4, (>80%). A case was scored as positive for CD163 with a score >= 1. The χ2 test was used to assess the CD163 expression in LSCC cases (N=80). A statistically significant difference was defined as P 0.05. Results The human larynx microarray containing 80 cases of LSCCs was used for this study. The age of the cancer patients in this array was in the range of 39 to 72, with a median of 53. LSCC grades were distributed as follows: 25 patients were designated as grade I, 43 were designated as grade II, and 6 were designated as grade III. Two tumors' (2/80) cores were missing from the microarray. Six tumors on the microarray did not have a grade designation reported by the manufacturer of the array. The expression of CD163 in normal, benign, unmatched laryngeal tissue was absent. In cancer cases, on the other hand, a significant number of LSCCs had TAMs that were positive for CD163 (87% positive tumors, with an IHC score ranging from 1 to 4, χ2=30.634; p<0.001). The rest of the LSCC cases (10 in total) had negative CD163 expression (score of 0). Conclusion A significant majority of LSCCs were found to have CD163+ TAMs expression using tissue microarrays (TMAs). This expression is positively correlated with the tumor's grade, clinical manifestation, and TNM staging. Morphologic evidence shows that the majority of LSCCs express the highest range of immunohistochemistry (IHC) scores for CD163 protein in the membranes and cytoplasm of their TAMs. This study provides evidence of the clinical significance of CD163+TAMs in LSCCs and proposes further studies to pinpoint the exact role of these cells in LSCC patients.

Abstract
Head and neck squamous cell carcinoma (HNSCC), the most common head and neck malignant tumor, with only monotherapy, is characterized by poor prognosis, and low 5-year survival rate. Due to the lack of therapeutic targets, the targeted drugs for HNSCC are rare. Therefore, exploring the regulation mechanism of HNSCC and identifying effective therapeutic targets will be beneficial to its treatment of. Circular RNA (CircRNA) is a class of RNA molecules with a circular structure, which is widely expressed in human body. CircRNAs regulate gene expression by exerting the function as a miRNA sponge, thereby mediating the occurrence and development of HNSCC cell proliferation, apoptosis, migration, invasion, and other processes. In addition, circRNAs are also involved in the regulation of tumor sensitivity to chemical drugs and other biological functions. In this review, we systematically listed the functions of circRNAs and explored the regulatory mechanisms of circRNAs in HNSCC from the aspects of tumor growth, cell death, angiogenesis, tumor invasion and metastasis, tumor stem cell regulation, tumor drug resistance, immune escape, and tumor microenvironment. It will assist us in discovering new diagnostic markers and therapeutic targets, while encourage new ideas for the diagnosis and treatment of HNSCC.

Abstract
Transcriptome expression profiles of laryngeal squamous cell carcinoma (LSCC) are altered, and we aimed to investigate expression and role of hsa_circ_0005033 (circ_0005033), microRNA (miR)-107 and insulin-like growth factor 1 receptor (IGF1R) in LSCC. Real-time PCR, western blotting and immunohistochemistry detected RNA and protein expression levels. Functional assays were performed using MTT assay, EdU assay, apoptosis assay, flow cytometry, Transwell assay, and xenograft tumor model. Direct interaction was predicted by Starbase algorithm and validated by dual-luciferase reporter assay and RNA immunoprecipitation. Expression of circ_0005033 was substantially upregulated in LSCC tissues and cells, and allied with miR-107 downregulation and IGF1R upregulation. Circ_0005033 showed a closed-loop structure and long half-life. Essentially, circ_0005033 and IGF1R were competing endogenous RNAs for miR-107 via target binding. Silencing circ_0005033 facilitated apoptosis rate and lowered cell viability, proliferation, migration and invasion of LSCC cells, as well as delayed xenograft tumor growth. Allied with that, cleaved-caspase 3/8/9 expression was elevated via death receptor-mediated and mitochondrial pathways, and expression of matrix metalloproteinase-2 (MMP2), MMP9, cyclin D1 and proliferating cell nuclear antigen was decreased. Moreover, Cisplatin-induced inhibition of cell viability was exacerbated by inhibiting circ_0005033. These functional effects of circ_0005033 depression were consistent with those of miR-107 overexpression. Furthermore, depleting miR-107 and restoring IGF1R abated the effects of circ_0005033 knockdown and miR-107 overexpression, respectively. Circ_0005033 was oncogenic in LSCC by regulating cell progression and Cisplatin sensitivity at least via miR-107/IGF1R axis.
