Identification of stemness-related glycosylation changes in head and neck squamous cell carcinoma. BMC Cancer 2024; 24:443. [PMID: 38600440 PMCID: PMC11005150 DOI: 10.1186/s12885-024-12161-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Accepted: 03/21/2024] [Indexed: 04/12/2024] Open
Abstract
BACKGROUND Altered glycosylation is a hallmark of cancer associated with therapy resistance and tumor behavior. In this study, we investigated the glycosylation profile of stemness-related proteins OCT4, CIP2A, MET, and LIMA1 in HNSCC tumors. METHODS Tumor, adjacent normal tissue, and blood samples of 25 patients were collected together with clinical details. After tissue processing, lectin-based glycovariant screens were performed. RESULTS Strong correlation between glycosylation profiles of all four stemness-related proteins was observed in tumor tissue, whereas glycosylation in tumor tissue, adjacent normal tissue, and serum was differential. CONCLUSIONS A mannose- and galactose-rich glycosylation niche associated with stemness-related proteins was identified.

Cancer/testis antigen CAGE mediates osimertinib resistance in non-small cell lung cancer cells and predicts poor prognosis in patients with pulmonary adenocarcinoma. Sci Rep 2023; 13:15748.

Abstract
CAGE, a cancer/testis antigen, was originally isolated from the sera of patients with gastric cancers. Previously, we have shown the role of CAGE in resistance to chemotherapy and target therapy. The aim of this study was to investigate the role of CAGE in osimertinib resistance and determine the prognostic value of CAGE in patients with pulmonary adenocarcinomas. The clinicopathological correlation with CAGE and autophagy flux in patients was examined using immunohistochemistry and in situ hybridization. The possible role of autophagy in osimertinib resistance was analyzed using immune blot, immune fluorescence staining and immunohistochemistry. This study found that immunohistochemical staining (IHC) showed CAGE expression in more than 50% of patients with pulmonary adenocarcinomas (pADCs). CAGE expression was increased in pADCs after the acquisition of EGFR-TKIs resistance. High expression of CAGE was correlated with shorter overall survival and progression free survival in patients with pADCs. Thus, CAGE mediates osimertinib resistance and predicts poor prognosis in patients with pADCs. Osimertinib-resistant non-small cell lung cancer cells (PC-9/OSI) were established and mechanistic studies of CAGE-mediated osimertinib resistance were performed. PC-9/OSI cells showed increased autophagic flux and CAGE expression compared with parental sensitive PC-9 cells. PC-9/OSI cells showed higher tumorigenic, metastatic, and angiogenic potential compared with parental PC-9 cells. CAGE CRISPR-Cas9 cell lines showed decreased autophagic flux, invasion, migration potential, and tumorigenic potential compared with PC-9/OSI cells in vitro and in vivo. CAGE plays a crucial role in the cancer progression by modulating autophagy and can predict the poor prognosis of patients with pulmonary adenocarcinomas. Our findings propose CAGE as a potential therapeutic target for developing anticancer drugs that can overcome osimertinib resistance.

ACACB is a novel metabolism-related biomarker in the prediction of response to cetuximab therapy inmetastatic colorectal cancer. Acta Biochim Biophys Sin (Shanghai) 2022; 54:1671-1683.

Abstract
Cetuximab is one of the most valuable targeted therapy monoclonal antibodies in the treatment of metastatic colorectal cancer (CRC). However, the mechanisms affecting cetuximab resistance in CRC treatment remain unclear. Metabolism, especially fatty acid metabolism, has been reported to play an important role in tumor treatment. The correlation between cetuximab resistance and metabolism and whether it can be a new biomarker to evaluate the sensitivity of cetuximab in CRC treatment still need to be further explored. In this study, we perform a comprehensive analysis to confirm the relationship between fatty acid metabolism and cetuximab resistance, and the differentially expressed genes (DEGs) related to cetuximab drug resistance in CRC are screened by bioinformatics technology. We find that acetyl-CoA carboxylase beta (ACACB), ADH1C, CES1, MGLL, FMO5, and GPT are the hub DEGs, and ACACB is the most important biomarker among them. In addition, we systematically analyze the role of ACACB in the tumorigenesis of CRC, including tissue expression, CRC cell growth, cetuximab sensitivity, and potential downstream pathways, by using bioinformatics techniques, in vitro experiments and clinical cohort validation. Our results confirm that cetuximab resistance is correlated with metabolism. ACACB can lead to decreased sensitivity to cetuximab in CRC, and its mechanism may be related to EGFR phosphorylation, which could affect the activation of the mTOR/Akt signaling pathway and regulation of CDT1-, cyclin D1-, and p21-related cell cycle modulation.

Cisplatin overcomes radiotherapy resistance in OCT4-expressing head and neck squamous cell carcinoma. Oral Oncol 2022; 127:105772.

Abstract
OBJECTIVES Cisplatin is combined with radiotherapy for advanced head and neck squamous cell carcinoma (HNSCC). While providing a beneficial effect on survival, it also causes side effects and thus is an important target when considering treatment de-escalation. Currently, there are no biomarkers to predict its patient-selective therapeutic utility. In this study, we examined the role of the stem cell factor OCT4 as a potential biomarker to help clinicians stratify HNSCC patients between radiotherapy and chemoradiotherapy. MATERIALS AND METHODS OCT4 immunohistochemical staining of a population-validated tissue microarray (PV-TMA) (n = 166) representative of a standard HNSCC patients was carried out, and 5-year survival was analyzed. The results were validated using ex vivo drug sensitivity analysis of HNSCC tumor samples, and further cross-validated in independent oropharyngeal (n = 118), nasopharyngeal (n = 170), and vulvar carcinoma (n = 95) clinical datasets. In vitro, genetically modified, patient-derived HNSCC cells were used. RESULTS OCT4 expression in HNSCC tumors was associated with radioresistance. However, combination therapy with cisplatin was found to overcome thisradioresistance in OCT4-expressing HNSCC tumors. The results were validated by using several independent patient cohorts. Furthermore, CRISPRa-based OCT4 overexpression in the HNSCC cell line resulted in apoptosis resistance, and cisplatin was found to downregulate OCT4 protein expression in vitro. Ex vivo drug sensitivity analysis of HNSCC tumors confirmed the association between OCT4 expression and cisplatin sensitivity. CONCLUSION This study introduces OCT4 immunohistochemistry as a simple and cost-effective diagnostic approach for clinical practice to identify HNSCC patients benefitting from radiosensitization by cisplatin using either full or reduced dosing.

Abstract
Background Cell-in-cell structures (caused by cell cannibalistic activity) have been related to prognosis of many cancers. This is the first multi-institutional study to assess the prognostic impact of cell-in-cell structures in a large cohort of early oral tongue squamous cell carcinomas (OTSCC). Methods A total of 308 cases from five Finnish University Hospitals and from the A.C. Camargo Cancer Center, São Paulo, Brazil, were included in this study. Cell-in-cell structures were evaluated on surgical postoperative sections that stained with hematoxylin and eosin staining. Results We found that cell-in-cell structures associated with cancer-related mortality in univariable analysis with a hazard ratio (HR) of 2.99 (95%CI 1.52–5.88; P = 0.001). This association was confirmed in multivariable analysis (HR 2.22, 95%CI 1.12–4.44; P = 0.024). In addition, statistically significant associations were observed between the cell-in-cell structures and other adverse histopathologic characteristics including deep invasion (P < 0.001), high index of tumor budding (P = 0.007), worst pattern of invasion (P < 0.001), perineural invasion (P = 0.01), and stroma-rich pattern (P = 0.001). Conclusions Our findings demonstrate a significant relationship between cell-in-cell formation and aggressive characteristics of early OTSCC. Cell-in-cell structures have a distinct impact as a novel prognostic indicator in early OTSCC and they can be easily assessed during routine pathology practice.

Abstract
Lin28, a highly conserved RNA-binding protein, plays an important role in differentiation, metabolism, proliferation, pluripotency, and tumourigenicity. Lin28 overexpression promotes tumour-cell proliferation and metastasis in various human cancers, including head and neck cancer. Multiple studies demonstrate that Lin28 critically contributes to anti-tumour immunity and production of cancer stem cells in head and neck squamous cell carcinoma (HNSCC). Thus, Lin28 has potential application in HNSCC treatment.

Abstract
Understanding the function of oral mucosal epithelial barriers is essential for a plethora of research fields such as tumor biology, inflammation and infection diseases, microbiomics, pharmacology, drug delivery, dental and biomarker research. The barrier properties are comprised by a physical, a transport and a metabolic barrier, and all these barrier components play pivotal roles in the communication between saliva and blood. The sum of all epithelia of the oral cavity and salivary glands is defined as the blood-saliva barrier. The functionality of the barrier is regulated by its microenvironment and often altered during diseases. A huge array of cell culture models have been developed to mimic specific parts of the blood-saliva barrier, but no ultimate standard in vitro models have been established. This review provides a comprehensive overview about developed in vitro models of oral mucosal barriers, their applications, various cultivation protocols and corresponding barrier properties.

Abstract
As soon as induced pluripotent stem cells (iPSCs) reprogramming of somatic cells were developed, the discovery attracted the attention of scientists, offering new perspectives for personalized medicine and providing a powerful platform for drug testing. The technology was almost immediately applied to cancer studies. As presented in this review, direct reprogramming of cancer cells with enforced expression of pluripotency factors have several basic purposes, all of which aim to explain the complex nature of cancer development and progression, therapy-resistance and relapse, and ultimately lead to the development of novel anti-cancer therapies. Here, we briefly present recent advances in reprogramming methodologies as well as commonalities between cell reprogramming and carcinogenesis and discuss recent outcomes from the implementation of induced pluripotency into cancer research.

Abstract
In cancer research, small animal models, for example, mice, rats, or rabbits, facilitate the in-depth study of biological processes and the effects of radiation treatment that can lead to breakthrough discoveries. However, the physical quality of small animal irradiation systems has not been previously evaluated. In this study, we evaluate the quality of a small animal irradiation system using GAFCHROMIC™ film and a Tough Water Phantom. The profiles and percentage depth dose curves for several irradiation conditions were measured to evaluate the quality of the irradiation system. The symmetry ratios when the table was rotated were 1.1 (no filter), 1.0 (0.5 mm Al filter), 1.0 (1.0 mm Al filter), 1.1 (2 mm Al filter), and 1.0 (filter consisting of 0.5 mm Al combined with 0.1 mm Cu). The results of measuring the percentage depth dose curve showed that the relative doses were 17.5% (10 mm depth), 12.4% (20 mm depth), 9.5% (30 mm depth), and 7.4% (40 mm filter) with no filters inserted, 78.0% (10 mm depth), 61.1% (20 mm depth), 46.9% (30 mm depth), and 35.3% (40 mm depth) when a 1.0 mm Al filter was inserted, and 94.4% (10 mm depth), 81.7% (20 mm depth), 68.1% (30 mm depth), and 54.7% (40 mm depth) when a filter consisting of 1.0 mm Al combined with 0.2 mm Cu was inserted. These physical assessments seem to be necessary especially in vivo experiments because those increase reliability of data obtained from small animal irradiation systems.
