Cell Signal 2023; 106:110635. [PMID: 36813147 DOI: 10.1016/j.cellsig.2023.110635] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 02/14/2023] [Accepted: 02/16/2023] [Indexed: 02/22/2023]
Abstract
OBJECTIVES Cancer-associated fibroblasts (CAFs) are vital constituents of the tumor microenvironment (TME) and play a predominant role in oral squamous cell carcinoma (OSCC) progression. We aimed to investigate the effect and mechanism of exosomal miR-146b-5p derived from CAFs on the malignant biological behavior of OSCC. MATERIALS AND METHODS Illumina small RNA (sRNA) sequencing was conducted to determine the differential expression patterns of microRNAs (miRNAs) in exosomes derived from CAFs and normal fibroblasts (NFs). Transwell and cell counting kit-8 (CCK-8) assays and xenograft tumor models in nude mice were used to investigate the effect of CAF exosomes and miR-146b-p on the malignant biological behavior of OSCC. Reverse transcription quantitative real-time PCR (qRT-PCR), luciferase reporter, western blotting (WB) and immunohistochemistry assays were employed to investigate the underlying mechanisms involved in CAF exosomes that promote OSCC progression. RESULTS We demonstrated that CAF-derived exosomes were taken up by OSCC cells and enhanced the proliferation, migration, and invasion ability of OSCC. Compared with NFs, the expression of miR-146b-5p was increased in exosomes and their parent CAFs. Further studies showed that the decreased expression of miR-146b-5p inhibited the proliferation, migration and invasion ability of OSCC cells in vitro and the growth of OSCC cells in vivo. Mechanistically, miR-146b-5p overexpression led to the suppression of HIKP3 by directly targeting the 3'-UTR of HIPK3, as confirmed by luciferase assay. Reciprocally, HIPK3 knockdown partially reversed the inhibitory effect of the miR-146b-5p inhibitor on the proliferation, migration, and invasion ability of OSCC cells and restored their malignant phenotype. CONCLUSIONS Our results revealed that CAF-derived exosomes contained higher levels of miR-146b-5p than NFs, and miR-146b-5p overexpression in exosomes promoted the malignant phenotype of OSCC by targeting HIPK3. Therefore, inhibiting exosomal miR-146b-5p secretion may be a promising therapeutic modality for OSCC.

A pilot study of neoadjuvant combination of anti-PD-1 camrelizumab and VEGFR2 inhibitor apatinib for locally advanced resectable oral squamous cell carcinoma. Nat Commun 2022; 13:5378. [PMID: 36104359 PMCID: PMC9472189 DOI: 10.1038/s41467-022-33080-8] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Accepted: 08/31/2022] [Indexed: 02/03/2023] Open
Abstract
Novel neoadjuvant therapy regimens are warranted for oral squamous cell carcinoma (OSCC). In this phase I trial (NCT04393506), 20 patients with locally advanced resectable OSCC receive three cycles of camrelizumab (200 mg, q2w) and apatinib (250 mg, once daily) before surgery. The primary endpoints are safety and major pathological response (MPR, defined as ≤10% residual viable tumour cells). Secondary endpoints include 2-year survival rate and local recurrence rate (not reported due to inadequate follow-up). Exploratory endpoints are the relationships between PD-L1 combined positive score (CPS, defined as the number of PD-L1-stained cells divided by the total number of viable tumour cells, multiplied by 100) and other immunological and genomic biomarkers and response. Neoadjuvant treatment is well-tolerated, and the MPR rate is 40% (8/20), meeting the primary endpoint. All five patients with CPS ˃10 achieve MPR. Post-hoc analysis show 18-month locoregional recurrence and survival rates of 10.5% (95% CI: 0%–24.3%) and 95% (95% CI: 85.4%–100.0%), respectively. Patients achieving MPR show more CD4+ T-cell infiltration than those without MPR (P = 0.02), and decreased CD31 and ɑ-SMA expression levels are observed after neoadjuvant therapy. In conclusion, neoadjuvant camrelizumab and apatinib is safe and yields a promising MPR rate for OSCC. In patients with locally advanced resectable oral squamous cell carcinoma (OSCC), the risk of recurrence and metastasis following treatment is high. Here, a phase I clinical trial reports safety and pathological response of neoadjuvant camrelizumab and apatinib in patients with locally advanced resectable OSCC.

Abstract
OBJECTIVE This systematic review was aimed to comprehensively evaluate the clinicopathological and prognostic value of dysregulated expression of circRNAs in OSCC. MATERIALS AND METHODS The research was carried out by searching mainstream electronic databases including PubMed, Embase, Web of Science, Scopus, LILACS and Cochrane Library to collect relevant studies on prognostic role of circRNAs in OSCC. Pooled hazard ratios (HRs) and odds ratios(ORs) with 95% confidence intervals(CIs) were calculated to assess the association between circRNAs expression, overall survival(OS), disease/recurrence/progression survival(DFS/RFS/PFS) and clinical parameters. RESULTS This research included 1813 patients from 26 selected articles. The pooled HR values(95% CIs) in OS were 2.38(1.92-2.93) for oncogenic circRNAs and 0.43(0.28-0.66) for tumor-suppressor circRNAs respectively, in DFS/RFS/PFS were 2.34(1.73-3.17). The meta-analysis on clinicopathology features showed higher level of oncogenic circRNAs is related to advanced TNM stage and tumor stage, worse histological differentiation, lymph node and distant metastasis, while enforced expression of tumor-suppressor circRNAs is related to inferior TNM stage tumor stage and lymphatic metastasis. CONCLUSION Our meta-analysis implies that circRNAs may be candidate biomarkers for the prognosis and clinicopathology of OSCC.

Abstract
Purpose This review describes the current scientific evidence of therapeutic options in unresectable oral squamous cell carcinoma. Methods This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We searched MEDLINE (Via PubMed) to identify studies assessing treatments for unresectable oral squamous cell carcinoma. The methodological quality assessment of the included studies was performed using the Joanna Briggs Institute (JBI) checklist tool. The evidence was organized and presented using tables and narrative synthesis. Results Thirty-three studies met the eligibility criteria. Most studies had an observational design. The sample size varied from 16 to 916 participants. The methodology quality of the included studies ranged from 2.5 to 10 using the JBI tool. Overall, the optimal treatment of patients with unresectable oral cancer is challenging, so there is a sprinkling of studies assessing a variety of therapeutic options, such as radiotherapy, chemotherapy, concurrent chemoradiotherapy, immunotherapy, targeted therapy plus chemotherapy or radiotherapy, and gene therapy plus chemotherapy. Conclusion There is lacking evidence about the benefits of some therapeutic options for unresectable oral squamous cell carcinoma. Overall, these patients can be treated using a multimodal approach such as concurrent chemoradiotherapy or induction chemotherapy followed by chemoradiotherapy, which have shown good clinical outcomes. However, other options could be considered depending on the assessment of risk/benefits, tumor extension, and patient values and preferences.

Abstract
The aims of this study were to determine the functional roles of the transmembrane glycoprotein, Disintegrin and metalloproteinase domain-containing protein 9 (ADAM 9), in the phosphorylation of epidermal growth factor receptor (EGFR) and AKT and in the aggressiveness of oral cancer cells. Immunohistochemistry and immunoblotting were conducted to determine expression of ADAM 9 and the levels of EGFR phosphorylated at the tyrosine 1173 residue (p-EGFRtyr1173 ) and AKT phosphorylated at the serine 473 residue (p-AKTser473 ) in oral cancer tissues and in the oral cancer cell lines HN5, HN6, HN15, and HN008. Small interfering RNA (siRNA) was used to inhibit expression of ADAM9 mRNA, and thus production of ADAM9 protein, in oral cancer cells. ADAM9-knockdown cells were examined for p-EGFRtyr1173 and p-AKTser473 levels and used for cell proliferation and invasion assays. A positive correlation among overexpression of ADAM 9, p-EGFRtyr1173 , and p-AKTser473 was found in oral cancer tissues. These biomolecules were also overexpressed in HN6 and HN15 cell lines. Expression of ADAM9 in HN6 and HN15 cells was statistically significantly inhibited by siRNA against ADAM9 mRNA (siADAM9) compared with the negative-control siRNA (scramble). The levels of p-AKTser473 , but not those of p-EGFRtyr1173 , were statistically significantly blocked by siADAM9. Although the proliferation rates of ADAM9 knocked-down HN6 and HN15 cells did not differ from those of cells exposed to scramble, a statistically significant decrease in cell invasion was found in these ADAM9-silenced cells. These results suggest a functional role of the ADAM 9/AKT signaling pathway in oral cancer cell invasion, which may be beneficial as a therapeutic target of oral cancer.

Abstract
BACKGROUND As a tumor-accelerating transcriptional factor, E2F transcription factor 7 (E2F7) was up-regulated in many forms of cancers. Nevertheless, little has been reported about the impacts of E2F7 on oral squamous cell carcinoma (OSCC). Here, we aimed to probe whether E2F7 had influences on OSCC and its potential mechanism. METHODS The expression of E2F7 in OSCC tissues was analyzed using the data acquired from TCGA and ONCOMINE databases. E2F7 prognostic value in OSCC patients was analyzed utilizing TCGA database. The expression of E2F7 in OSCC cell lines was detected by qRT-PCR. Gain-and loss-function of E2F7 assays in TCA-83 and CAL27 cells were performed respectively to inquire the function of E2F7. Western blotting was applied to test the alternations of EMT-related markers. RESULTS In OSCC tissues, E2F7 was highly expressed. Besides, high expression of E2F7 predicted worse prognosis in OSCC patients. Moreover, E2F7 was over-expressed in TCA-83, HSC-4 and CAL27 (all OSCC cell lines) cells relative to that in HNOK (a normal cell line) cells. Gain-and loss-function assays displayed that deficiency of E2F7 suppresses CAL27 cell growth, migration, invasion and E2F7 high-expression resulted in inverse outcomes in TCA-83 cells. Finally, we found that silencing of E2F7 facilitated E-cadherin protein expression level and reduced N-cadherin, Vimentin and Snail protein levels in CAL27 cells, whilst E2F7 high-expression exhibited the opposite effects in TCA-83 cells. CONCLUSIONS These outcomes indicated that E2F7 performs a carcinogenic role in OSCC, which provides a theoretical basis for the therapeutic strategies of OSCC.

Front Public Health 2021; 9:631118.

Abstract
Oral cancer is a very aggressive disease with high rates of recurrence and metastasis. This study aimed at addressing how efficiently tongue cancer is suppressed after carbon ion irradiation. Here, the close relationship between upregulated expression of focal adhesion kinase (FAK) and high metastatic status in tongue squamous cell carcinoma patients was validated using bioinformatics and immunohistochemical analyses. Our data indicated that FAK suppression significantly enhanced the killing effect induced by irradiation in the tongue cancer cell line CAL27, as evidenced by increased apoptotic induction and reduced colony formation. More importantly, in FAK-deficient cells, carbon ion irradiation was shown to remarkably inhibit migration and invasion by delaying wound healing and slowing down motility. Further studies revealed that irradiation exposure caused disorganization of the actin cytoskeleton and reduced cell adhesive energy in FAK-deficient cells. Moreover, carbon ion treatment, in combination with FAK silencing, markedly blocked the phosphorylation levels of FAK, and paxillin, which partly contributed to the reduced motility of tongue squamous cell carcinoma CAL27 cells. Collectively, these results suggest that the prominent obstructing role of carbon ion irradiation in the growth inhibition and metastatic behavior of tumors, including attenuation of cell adhesiveness, motility, and invasiveness, could be distinctly modulated by FAK-mediated downstream pathways.

Abstract
Oral squamous cell carcinoma (OSCC) is currently ranked as the eighth most prevalent type of cancer. Despite recent advances in cancer research, the 8-year survival rate for oral squamous cell carcinoma remains only 50–60%. Therefore, markers for early detection, identification of efficient chemotherapeutic agents, and post-therapeutic monitoring are the immediate needs. With this background, this study was designed to investigate the anticancer effects of vitamin C (VC) in oral squamous cell carcinoma. Our results showed that VC had an anticancer effect on the oral squamous cell lines used in this study. VC also showed an inhibitory effect on xenograft tumors in nude mice in vitro and had a synergistic effect with cisplatin to induce cell apoptosis. Mechanistically, VC caused a significant increase in the levels of reactive oxygen species (ROS), which led to induced genotoxic (DNA damage) and metabolic (ATP depletion) stresses, inhibited Bcl-2 expression, and promoted Bax expression and caspase-3 cleavage. VC also caused cell cycle arrest at the G0/G1 phase in OSCC cells, which is related to the activation of tumor suppressor p53 and cyclin-dependent kinase inhibitor p21. In conclusion, VC bears considerable therapeutic potential for the treatment of oral squamous cell carcinoma.

Abstract
Background Oral squamous cell carcinoma (OSCC) is one of the most common malignant tumors worldwide. Patients with poorly differentiated OSCC often exhibit a poor prognosis. AUNIP (Aurora Kinase A and Ninein Interacting Protein), also known as AIBp, plays a key role in cell cycle and DNA damage repair. However, the function of AUNIP in OSCC remains elusive. Methods The differentially expressed genes (DEGs) were obtained using R language. Receiver operating characteristic curve analysis was performed to identify diagnostic markers for OSCC. The effectiveness of AUNIP in diagnosing OSCC was evaluated by machine learning. AUNIP expression was analyzed in publicly available databases and clinical specimens. Bioinformatics analysis and in vitro experiments were conducted to explore biological functions and prognostic value of AUNIP in OSCC. Findings The gene integration analysis revealed 90 upregulated DEGs. One candidate biomarker, AUNIP, for the diagnosis of OSCC was detected, and its expression gradually increased along with malignant differentiation of OSCC. Bioinformatics analysis demonstrated that AUNIP could be associated with tumor microenvironment, human papillomavirus infection, and cell cycle in OSCC. The suppression of AUNIP inhibited OSCC cell proliferation and resulted in G0/G1 phase arrest in OSCC cells. The survival analysis showed that AUNIP overexpression predicted poor prognosis of OSCC patients. Interpretation: AUNIP could serve as a candidate diagnostic and prognostic biomarker for OSCC and suppression of AUNIP may be a potential approach to preventing and treating OSCC.
