Knockdown of c-MYC Controls the Proliferation of Oral Squamous Cell Carcinoma Cells in vitro via Dynamic Regulation of Key Apoptotic Marker Genes. INTERNATIONAL JOURNAL OF MOLECULAR AND CELLULAR MEDICINE 2021; 10:45-55. [PMID: 34268253 PMCID: PMC8256829 DOI: 10.22088/ijmcm.bums.10.1.45] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 05/09/2021] [Indexed: 01/09/2023]
Abstract
Oral squamous cell carcinoma (OSCC) is the most common malignant epithelial cancer occurring in the oral cavity, where it accounts for nearly 90% of all oral cavity neoplasms. The c-MYC transcription factor plays an important role in the control of programmed cell death, normal-to-malignant cellular transformation, and progression of the cell cycle. However, the role of c-MYC in controlling the proliferation of OSCC cells is not well known. In this study, c-MYC gene was silenced in OSCC cells (ORL-136T), and molecular and cellular responses were screened. To identify the pathway through which cell death occurred, cytotoxicity, colony formation, western blotting, caspase-3, and RT-qPCR analyzes were performed. Results indicated that knockdown of c-MYC has resulted in a significant decrease in the cell viability and c-MYC protein synthesis. Furthermore, caspase-3 was shown to be upregulated leading to apoptosis via the intrinsic pathway. In response to c-MYC knockdown, eight cell proliferation-associated genes showed variable expression profiles: c-MYC (-21.2), p21 (-2.5), CCNA1(1.8), BCL2 (-1.4), p53(-3.7), BAX(1.1), and CYCS (19.3). p27 expression was dramatically decreased in c-MYC-silenced cells in comparison with control, and this might indicate that the relative absence of c-MYC triggered intrinsic apoptosis in OSCC cells via p27 and CYCS.

Abstract
To discover the effect of tumor necrosis factor-alpha-induced protein 8-like 2 (TIPE2) on the oral tongue squamous cell carcinoma (OTSCC) via affecting FoxP3+ regulatory T (Treg) cells. Immunohistochemistry was conducted to examine TIPE2 and FoxP3 expressions in OTSCC tumor tissues and corresponding oral mucosa. Tca8113 cells were transfected with TIPE2/control lentiviral activation particles followed by the detection with qRT-PCR, Western blotting, MTT assay, Wound healing, Transwell assay and Annexin V-FITC/PI staining. In vivo experiment was carried out on the nude mice xenografts of OTSCC with TIPE2 overexpression to observe the tumor volume and survival, and the CD4+ T cell subgroups were detected by flow cytometry. TIPE2 was lower in the OTSCC tissues than the corresponding oral mucosa, which was correlated with T stage, N stage, TNM stage, and differentiation of patients. Patients with TIPE2-positive expression had worse prognosis and lower expression of FoxP3+ Treg cells than the negative ones. Furthermore, TIPE2 overexpression curbed proliferation, invasion and migration of Tca8113 cells, while cell apoptosis was increased. Besides, TIPE2 suppressed the tumor growth and extended the survival of OTSCC mice, with the decreased proportion of FoxP3+ Treg cells in the spleen and tumor-infiltrated lymphocytes (TILs). The clinical results showed the down-regulation of TIPE2 in OTSCC tissues. Meanwhile TIPE2 overexpression affected OTSCC cells biological behavior in vitro, as well as exhibited strong tumor-growth suppressive effects in vivo, which may be a potential therapeutic target in OTSCC via regulating FoxP3+ Treg cells.

Abstract
The oral microbiota plays an important role in the human microbiome and human health, and imbalances between microbes and their hosts can lead to oral and systemic diseases and chronic inflammation, which is usually caused by bacteria and contributes to cancer. There may be a relationship between oral bacteria and oral squamous cell carcinoma (OSCC); however, this relationship has not been thoroughly characterized. Therefore, in this study, we compared the microbiota compositions between tumor sites and opposite normal tissues in buccal mucosal of 50 patients with OSCC using the 16S rDNA sequencing. Richness and diversity of bacteria were significantly higher in tumor sites than in the control tissues. Cancer tissues were enriched in six families (Prevotellaceae, Fusobacteriaceae, Flavobacteriaceae, Lachnospiraceae, Peptostreptococcaceae, and Campylobacteraceae) and 13 genera, including Fusobacterium, Alloprevotella and Porphyromonas. At the species level, the abundances of Fusobacterium nucleatum, Prevotella intermedia, Aggregatibacter segnis, Capnocytophaga leadbetteri, Peptostreptococcus stomatis, and another five species were significantly increased, suggesting a potential association between these bacteria and OSCC. Furthermore, the functional prediction revealed that genes involved in bacterial chemotaxis, flagellar assembly and lipopolysaccharide (LPS) biosynthesis which are associated with various pathological processes, were significantly increased in the OSCC group. Overall, oral bacterial profiles showed significant difference between cancer sites and normal tissue of OSCC patients, which might be onsidered diagnostic markers and treatment targets. Our study has been registered in the Chinese clinical trial registry (ChiCTR1900025253, http://www.chictr.org.cn/index.aspx).

[PMID: 31983439 DOI: 10.1016/j.suronc.2019.12.001] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2019] [Revised: 11/07/2019] [Accepted: 12/05/2019] [Indexed: 11/24/2022]
Abstract
Growing evidences have demonstrated a pivotal role of chronic inflammation in oral squamous cell carcinoma (OSCC) through the modulation of inflammatory cells and cytokine production. IL-37 is newly discovered anti-inflammatory member of IL-1 family and can bind to IL-18 receptor to inhibit IL-18 (pro-inflammatory member of IL-1 family) function. Investigation on the balance of IL-18/IL-37 would provide new insights into the function of IL-1 family in OSCC. Thus, serum IL-18 and IL-37 levels of OSCC patients (n = 108), leukoplakia patients (n = 40), and healthy donors (n = 36) were collected to analyze the balance of IL-18 and IL-37, and also determine their diagnostic value and prognostic significance in OSCC. The results showed that OSCC patients had high IL-18 and low IL-37 levels in serum and peripheral blood mononuclear cell (PBMC). The ratio of IL-18/IL-37 in serum efficiently distinguished non-cancer individuals from OSCC patients (cut off value: 2.15). Moreover, patients with high IL-18 and low IL-37 were susceptible to develop advanced tumor stage and lymph node metastasis (Odd ratios of IL-18/IL-37 is 4.903 and 12.613, respectively). Meanwhile, higher IL-18/IL-37 ratio could predict shorter overall survival and disease-free survival of OSCC patients, although it was not an independent prognostic factor. We further analyze the correlations of serum IL-18/IL-37 with immunocytes in peripheral blood and found that high IL-18 level was associated with more CD19+ B cells, while serum IL-37 seem to be associated with reduced percentage of CD3+CD8+ T cells, indicating its balance could change the adaptive immune response. Unexpectedly, we first revealed the different function of IL-18/IL-37 in serum and tumor tissues. High mRNA expression of IL-18 in tumor tissues correlated with low lymph node metastasis rate and low tumor stage, which was contradictory to the pro-tumor role of IL-18 in serum. In conclusion, enhanced ratio of IL-18/IL-37 level in serum could be an efficient biomarker for OSCC. Its balance might regulate CD19+ B cells and CD3+ CD8+ T cells for OSCC progression.

Abstract
We introduced polyethyleneimine (PEI)-cholesterol (PC) as a nanocarrier incorporating berberine (BER) and miR-122 for the treatment of oral squamous cell carcinoma (OSCC). BER was stabilized by incorporating PC to form ber-PC. Ber-PC was further electrostatically complexed with miR-122 to yield mr-ber-PC for the co-delivery of BER and miR-122. mr-ber-PC treatment dramatically decreased the level of invasion and migration of OSCC cells compared with single drug treatments. The present study suggested that PC could be a multifunctional nanocarrier for the co-delivery of anticancer drug BER and miR-122 to significantly increase the anticancer therapeutic effects.

Abstract
MicroRNAs have been used as diagnostic and prognostic biomarkers for many cancers including oral squamous cell carcinoma (OSCC). Several studies have been shown that microRNA (miRNA) play important roles during the progression of OSCC. However, the results vary largely in different studies due to different platforms and sample sizes. In this study, we systematically evaluated a large scale of miRNA profiles from current qualified OSCC samples, and further investigated the functions of genes regulated by these key miRNAs as well as the signaling pathways through which these miRNA effect carcinogenesis. Seven key miRNAs were identified, and of which three were significantly upregulated, including hsa-miR-21, hsa-miR-31, hsa-miR-338, and four were downregulated, namely hsa-miR-125b, hsa-miR-133a, hsa-miR-133b, and hsa-miR-139. The function enrichment analysis revealed that target genes of upregulated miRNAs were associated with cellular protein metabolic process, macromolecule metabolic process, and TGF-beta pathway, while the targets of downregulated were enriched in negative regulation of macromolecule biosynthetic process and gene expression, and p53, long-term potentiation and adherens junction pathways. Transcription factor analysis revealed that there were 67 (51.1%) transcription factors influenced by both up and downregulated miRNAs. In summary, seven key miRNAs were found to play essential role in progression of OSCC, as well as the target genes and transcription factors of these miRNAs. The potential functions of these target genes identified in our study may be profitable to diagnosis and prognostic prediction of OSCC as biomarkers. J. Cell.

Abstract
Objective This study explored the level and clinical significance of serum Gas6 in patients with oral squamous cell carcinoma (OSCC). Methods A total of 128 OSCC patients and 145 normal controls were selected. Enzyme-linked immunosorbent assay was used to detect Gas6 concentration in sera from the OSCC patients and controls. The correlations of serum Gas6 concentration and clinicopathological characteristics of OSCC patients were assessed, and the prognostic significance of serum Gas6 was evaluated with a Kaplan–Meier curve and log-rank test. Results The results showed that serum Gas6 concentration was significantly higher in OSCC patients than in controls (P < 0.05). OSCC patients with late TNM stage (III, IV) had a relatively high serum Gas6 concentration compared with those with early stage (I, II) (P < 0.01) and patients with poorly differentiated tumors had a higher level of serum Gas6 than those with well-differentiated tumors (P < 0.01). Multivariate logistic regression analysis demonstrated that high serum Gas6 was an independent risk factor for lymph nodal metastases in OSCC patients (OR = 2.79, 95% CI: 1.72–4.48). For predicting OSCC development, ROC curve analysis showed a sensitivity of 0.63 with a specificity of 0.92 (AUC = 0.79, 95% CI: 0.74–0.85). Cox analysis revealed that high serum Gas6 was an independent biomarker for predicting poor overall survival in OSCC patients (HR = 2.07, 95% CI: 1.79–3.62). In addition, we found that Gas6 expression was increased in OSCC tissues and it may significantly decrease E-cadherin expression, and increase P-cadherin and N-cadherin expression, in OSCC cells. Further, Gas6 could promote the migratory and invasive ability of OSCC cells in vitro. Conclusion Taken together, these results suggest that Gas6 increases the metastatic capacity of OSCC cells and serum Gas6 could be a candidate biomarker for diagnostic and prognostic use in OSCC patients.
