Abstract
BACKGROUND/PURPOSE Smoking is a major contributor to global oral cancer cases, necessitating urgent intervention. FOXD1, involved in developmental processes and various cancers, shows promise as a prognostic marker in oral squamous cell carcinoma (OSCC). This study investigates the impact of waterpipe smoke condensate (WPSC) on OSCC, focusing on FOXD1 role in inducing epithelial-mesenchymal transition (EMT) and metastasis. METHODS The study involved using OSCC cells treated with WPSC to evaluate their proliferation, colony formation, gene expression, and protein levels. The researchers also explored the clinical relevance of their findings using online databases to analyze FOXD1 expression in cancer tissues and its correlation with clinicopathological features and patient survival. Additionally, in silico tools were employed for functional analysis, pathway enrichment, and network exploration. RESULTS The study found that WPSC increased the expression of FOXD1 in OSCC cells, which led to increased cell growth. The study also showed that FOXD1 plays a critical role in the EMT process induced by WPSC, as evidenced by changes in the expression of EMT-related genes and proteins. Clinical analysis revealed that FOXD1 was significantly associated with more aggressive tumor features and poorer prognosis in cancer patients. CONCLUSION The study highlights FOXD1 as a key player in OSCC pathogenesis and a potential prognostic marker and therapeutic target, particularly when influenced by WPSC exposure. Further research is needed to explore FOXD1 molecular mechanisms and clinical implications to enhance OSCC treatment strategies.

Cureus 2023; 15:e50202. [PMID: 38192945 PMCID: PMC10772308 DOI: 10.7759/cureus.50202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 12/05/2023] [Indexed: 01/10/2024] Open
Abstract
Introduction Lipase C hepatic type (LIPC) is a member of the lipase family and plays a role in tumor development. However, its specific role in head and neck squamous cell carcinoma (HNSCC) is not well understood. Objective This study aims to investigate LIPC gene expression in HNSCC and elucidate its potential role in the context of the disease. Methods LIPC expression was analyzed using the Cancer Genome Atlas-HNSCC (TCGA-HNSCC) dataset. Real-time polymerase chain reaction (qPCR) was used to validate LIPC expression in oral squamous cell carcinoma (OSCC) tissue samples, which is the most common type of HNSCC. The LIPC was assessed to find out if there is a link with HNSCC clinicopathological features, prognosis, and tumor infiltration. Functional pathways associated with the LIPC network were also examined. Results LIPC expression was found to be elevated in both HNSCC and OSCC tissues. The heightened expression of LIPC correlated with various clinicopathological features and influenced the prognosis of HNSCC patients. The LIPC gene demonstrated connections with several oncogenic genes and proteins, participating in lipid catabolic processes and other pathways. These findings suggest that LIPC expression may play a role in the pathogenesis of HNSCC. Conclusion Our study affirms that LIPC expression is linked to the development of HNSCC, suggesting its potential utility as a biomarker or therapeutic target for the disease. However, further functional studies are imperative to validate and expand upon these findings.

JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2023; 124:101617. [PMID: 37666484 DOI: 10.1016/j.jormas.2023.101617] [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: 07/16/2023] [Accepted: 08/30/2023] [Indexed: 09/06/2023]
Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is one of the most aggressive types of cancers worldwide, with metastasis being the major cause of death. Recent research suggests that changes in the expression of MRC2 (mannose receptor, C-type 2) may play a role in the development and progression of various cancers; however, its expression pattern in HNSCC/ OSCC is unknown. This study aimed to elucidate the clinicopathological significance and prognostic role of MRC2 expression in HNSCC, including OSCC. MATERIALS AND METHODS In the present study, we assessed the potential roles of MRC2 in expression, prognostic value, immune infiltration and functional enrichment analysis in HNSCC patients by using different bioinformatics databases. We then validated MRC2 gene expression in 30 OSCC and adjacent normal tissue samples using quantitative reverse transcription PCR (RT-qPCR). RESULTS MRC2 mRNA and protein expression were significantly upregulated in OSCC and HNSCC patients compared to that in adjacent normal tissues. Upregulated MRC2 expression was associated with poor overall survival. Increased MRC2 expression has also been linked to an aggressive clinicopathological features including advanced stages, grade, metastasis and HPV status. Interestingly, our in silico results strongly suggest that the MRC2 gene and protein interaction networks are associated with HNSCC development. Moreover, the tumor infiltration level was significantly correlated with HPV-negative HNSCC patients. CONCLUSION Our results suggest that MRC2 could be used as a novel prognostic marker and therapeutic target for HNSCC.

[PMID: 37820185 PMCID: PMC10561964 DOI: 10.1590/1678-7757-2023-0243] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 08/17/2023] [Accepted: 08/21/2023] [Indexed: 10/13/2023] Open
Abstract
OBJECTIVE Gossypetin, isolated from Hibiscus sabdariffa L, has been shown to have various pharmacological effects including anti-inflammatory and antibacterial activity against various diseases. However, since the effect of gossypetin in oral cancer remains to be reported, we aimed to investigate the anticancer activity and mechanisms of gossypetin in oral squamous cell carcinoma (OSCC). METHODOLOGY The proliferation of OSCC cells was evaluated by cell viability and soft agar colony assays. The effects of gossypetin on the migration and invasion of OSCC cells was investigated by wound healing and transwell invasion assays, respectively. Apoptosis and cell cycle arrest were measured by flow cytometry. Moreover, the anticancer mechanism of gossypetin in OSCC cells was analyzed by western blotting. RESULTS Gossypetin inhibited the proliferation, migration, and invasion of OSCC cells and induced apoptosis by upregulating the Bax/Bcl-2 ratio and cell cycle arrest at the G2/M phase. Furthermore, gossypetin regulated the activation of extracellular signal-regulated kinase and nuclear factor-kappa B. CONCLUSION Results showed that gossypetin inhibits the proliferation, migration, and invasion of OSCC cells and triggers apoptosis and cell cycle arrest in OSCC. Therefore, gossypetin has the potential for use as a chemopreventive agent in oral cancer.
