Abstract
MicroRNA-31 (miR-31) is overexpressed in esophageal squamous cell carcinoma (ESCC), a deadly disease associated with dietary Zn deficiency and inflammation. In a Zn deficiency-promoted rat ESCC model with miR-31 up-regulation, cancer-associated inflammation, and a high ESCC burden following N-nitrosomethylbenzylamine (NMBA) exposure, systemic antimiR-31 delivery reduced ESCC incidence from 85 to 45% (P = 0.038) and miR-31 gene knockout abrogated development of ESCC (P = 1 × 10-6). Transcriptomics, genome sequencing, and metabolomics analyses in these Zn-deficient rats revealed the molecular basis of ESCC abrogation by miR-31 knockout. Our identification of EGLN3, a known negative regulator of nuclear factor κB (NF-κB), as a direct target of miR-31 establishes a functional link between oncomiR-31, tumor suppressor target EGLN3, and up-regulated NF-κB-controlled inflammation signaling. Interaction among oncogenic miR-31, EGLN3 down-regulation, and inflammation was also documented in human ESCCs. miR-31 deletion resulted in suppression of miR-31-associated EGLN3/NF-κB-controlled inflammatory pathways. ESCC-free, Zn-deficient miR-31-/- rat esophagus displayed no genome instability and limited metabolic activity changes vs. the pronounced mutational burden and ESCC-associated metabolic changes of Zn-deficient wild-type rats. These results provide conclusive evidence that miR-31 expression is necessary for ESCC development.

A comparative study: the prospective influence of nanovectors in leveraging the chemopreventive potential of COX-2 inhibitors against skin cancer. Int J Nanomedicine 2019; 14:7561-7581. [PMID: 31571864 PMCID: PMC6756578 DOI: 10.2147/ijn.s218905] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Accepted: 08/18/2019] [Indexed: 01/01/2023] Open
Abstract
Introduction This study was conducted to elucidate the chemopreventive potential, cytotoxic, and suppression of cellular metastatic activity of etodolac (ETD)-loaded nanocarriers. Methods To esteem the effect of charge and composition of the nanovectors on their performance, four types of vectors namely, negative lipid nanovesicles; phosalosomes (N-Phsoms), positive phosalosomes (P-Phsoms), nanostructured lipid carriers (NLCs) and polymeric alginate polymer (AlgNPs) were prepared and compared. ETD was used as a model cyclo-oxygenase-2 (COX-2) inhibitor to evaluate the potency of these nanovectors to increase ETD permeation and retention through human skin and cytotoxicity against squamous cell carcinoma cell line (SCC). Moreover, the chemopreventive activity of ETD nanovector on mice skin cancer model was evaluated. Results Among the utilized nanovectors, ETD-loaded N-Phsoms depicted spherical vesicles with the smallest particle size (202.96±2.37 nm) and a high zeta potential of −24.8±4.16 mV. N-Phsoms exhibited 1.5, and 3.6 folds increase in the ETD amount deposited in stratum corneum, epidermis and dermis. Moreover, cytotoxicity studies revealed a significant cytotoxic potential of such nanovector with IC50=181.76 compared to free ETD (IC50=982.75), correlated to enhanced cellular internalization. Its efficacy extended to a reduction in the relative tumor weight with 1.70 and 1.51-fold compared to positive control and free ETD, that manifested by a 1.72-fold reduction in both COX-2 and proliferating cell nuclear antigen mRNA (PCNA-mRNA) levels and 2.63-fold elevation in caspase-3 level in skin tumors relative to the positive control group with no hepato-and nephrotoxicity. Conclusion Encapsulation of ETD in nanovector enhances its in-vitro and in-vivo anti-tumor activity and opens the door for encapsulation of more relevant drugs.

Abstract
OBJECTIVE To study the potential for apoptosis induction of Dracaena cinnabari Balf. f methanolic extract (DCBME) on tongue squamous cell carcinoma cell line, H103. We evaluated the chemopreventive activity of DCBME against 4-nitroquinolone-1-oxide (4NQO)-induced tongue carcinogenesis in rat. DESIGN Phase contrast microscope, acridine orange/propidium iodide (AO/PI) analysis of cells under fluorescence microscope, annexin-V flow-cytometry, DNA fragmentation, mitochondrial membrane potential, and caspase 3/7, 8 and 9 assays were performed. In vivo study, the rats were given 4NQO in their drinking water. The tongue was subjected to histopathological study to evaluate the incidence of squamous cell carcinoma (SCC). RESULTS DCBME showed cytotoxic effect on H103 cells in a dose- and time-dependent manner. Furthermore, DCBME showed low cytotoxic effect on a normal cell line. In H103 cells, it caused cell morphology changes, S and G2/M-phase cell cycle arrest, significant reduction of cell migration and induced apoptosis through the intrinsic (mitochondrial) pathway. The incidence of SCC was 85.7% in the induced cancer and vehicle groups while in rats treated with DCBME at 100, 500 and 1000 mg/kg was 57.1%, 28.6% and 14.3%, respectively. CONCLUSIONS (DCBME)-apoptosis induction reported in this work can be exploited as a potential antitumor agent with applications in medicinal treatments of tongue SCC.

Changes in the expression of the potassium channels TASK1, TASK3 and TRESK in a rat model of oral squamous cell carcinoma and their relation to malignancy. Arch Oral Biol 2019; 100:75-85. [PMID: 30818127 DOI: 10.1016/j.archoralbio.2019.02.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 01/30/2019] [Accepted: 02/15/2019] [Indexed: 12/21/2022]
Abstract
OBJECTIVES Potassium channels have been proposed to promote cancer cell proliferation and metastases. Thus, we investigated the expression pattern of three 2-pore domain potassium channels (K2Ps) TASK1, TASK3 and TRESK in advanced oral squamous cell carcinoma (OSCC), the commonest oral malignancy. DESIGN We used 4-nitroquinoline-1-oxide (4-NQO) to induce high grade OSCC in male adult rats. We then used immunohistochemistry and Western blotting to study the distribution and expression pattern of TASK1, TASK3 and TRESK in normal versus cancerous tissue. We also examined the expression of β-tubulin III (β-tub3), a marker associated with resistance to taxane-based chemotherapy and poor patient prognosis, and its correlation with the K2Ps. Finally, we studied the expression of TASK1, TASK3 and TRESK in human samples of SCC of oral origin. RESULTS We found that TASK3 was significantly up-regulated whereas TASK1 and TRESK were both significantly down-regulated in advanced, poorly differentiated OSCC. Both, rat and human SCC showed a significant increase in the expression of β-tub3. Interestingly, the expression of the latter correlated positively and significantly with TASK3 and TRESK but not TASK1 in rat OSCC. Our initial results showed a similar pattern of up and down regulation and correlation with β-tub3 for these three K2Ps in human SCC. CONCLUSIONS The changes in expression and the co-localization with a marker of resistance to taxanes like β-tub3 turn TASK1, TASK3 and TRESK into potentially new prognostic tools and possibly new therapeutic targets for OSCC.

Abstract
OBJECTIVES In vivo study was performed to determine the chemopreventive efficacy of the DC resin methanol extract on a 4-nitroquinoline-1-oxide (4NQO) oral cancer animal model. MATERIALS AND METHODS This study involves administration of 4NQO solution for 8 weeks alone (cancer induction) or with Dracaena cinnabari (DC) extract at 100, 500, and 1000 mg/kg. DC extract administration started 1 week before exposure until 1 week after the carcinogen exposure was stopped. All rats were sacrificed after 22 weeks, and histological analysis was performed to assess any incidence of pathological changes. Immunohistochemical expressions of selected tumor marker antibodies were analyzed using an image analyzer computer system, and the expression of selected genes involved in apoptosis and proliferative mechanism related to oral cancer were evaluated using RT2-PCR. RESULTS The incidence of OSCC decreased with the administration of DC extract at 100, 500, and 1000 mg/kg compared to the induced cancer group. The developed tumor was also observed to be smaller when compared to the induced cancer group. The DC 1000 mg/kg group inhibits the expression of Cyclin D1, Ki-67, Bcl-2, and p53 proteins. It was observed that DC 1000 mg/kg induced apoptosis by upregulation of Bax and Casp3 genes and downregulation of Tp53, Bcl-2, Cox-2, Cyclin D1, and EGFR genes when compared to the induced cancer group. CONCLUSIONS The data indicated that systemic administration of the DC resin methanol extract has anticarcinogenic potency on oral carcinogenesis. CLINICAL RELEVANCE Chemoprevention with DC resin methanol extract may significantly reduce morbidity and possibly mortality from OSCC.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is a frequently fatal disease due, in large part, to a high rate of second primary tumor (SPT) formation. The 4-nitroquinoline 1-oxide (4-NQO) mouse model of oral carcinogenesis provides a robust system in which to study chemopreventive agents in the context of chemically induced HNSCC tumors. STAT3 is a potent oncogene that is hyperactivated by tyrosine phosphorylation early in HNSCC carcinogenesis and is a rational therapeutic target. We recently reported that loss-of-function of the STAT3 phosphatase PTPRT promotes STAT3 activation in HNSCC tumors and preclinical models and may serve as a predictive biomarker of response to STAT3 inhibitors, including the small-molecule Stattic. We therefore investigated the hypothesis that Ptprt-knockout (KO) mice would be more susceptible to 4-NQO-induced oral carcinogenesis and more sensitive to Stattic-mediated chemoprevention compared with wild-type (WT) mice. Herein, we demonstrate that Ptprt WT and KO mice develop similar spectra of HNSCC disease severity upon 12 weeks of 4-NQO administration, with no apparent effect of Ptprt genotype on carcinogenesis or treatment outcome. Targeting of STAT3 with Stattic resulted in a chemopreventive effect against 4-NQO-induced oral cancer (P = 0.0402). While these results do not support a central role for PTPRT in 4-NQO-induced HNSCC carcinogenesis, further investigation of STAT3 as a chemoprevention target in this cancer is warranted.

Abstract
OBJECTIVES Lymph node metastasis is one of the most important prognostic factors in oral squamous cell carcinoma. However, regional lymph node metastasis from oral cancer has barely been investigated in 4-nitroquinoline-1-oxide (4NQO) models. In this study, we developed a 4NQO-treated mouse model of oral squamous cell carcinoma that displayed lymph node metastasis and examined the occurrence and timing of the lymph node metastasis. MATERIALS AND METHODS BALB/c mice were treated with 200 μg/ml 4NQO in drinking water for 20 weeks and then followed for 4 weeks. Four mice were sacrificed bi-weekly, and oral lesion and regional lymph node metastasis were assessed during the week 25-32 and week 33-40 observation periods. RESULTS Tumor formation and local lymph enlargement were observed from 25 weeks onwards. The presence of metastatic tumor cells in the enlarged lymph nodes was confirmed via the detection of tumor infiltration by HE staining and cytokeratin positivity by immunostaining at both 28 and 36 weeks. The incidence rates of oral squamous cell carcinoma and local lymph node metastasis were 68.8% and 12.5% in the week 25-32 observation period, and 100% and 100% in the week 33-40 observation period, respectively. CONCLUSIONS A lymph node metastasis model involving mice being subjected to high-dose 4NQO treatment for a long period and then followed for a prolonged period was established. This model might provide a platform for studying the mechanism of lymphatic metastasis in oral carcinoma, leading to the development of new therapies for advanced oral carcinoma.

Abstract
Chronic inflammation is implicated in the pathogenesis of esophageal squamous cell carcinoma (ESCC). The causes of inflammation in ESCC, however, are undefined. Dietary zinc (Zn)-deficiency (ZD) increases the risk of ESCC. We have previously shown that short-term ZD (6 weeks) in rats induces overexpression of the proinflammatory mediators S100a8 and S100a9 in the esophageal mucosa with accompanying esophageal epithelial hyperplasia. Here we report that prolonged ZD (21 weeks) in rats amplified this inflammation that when combined with non-carcinogenic low doses of the environmental carcinogen, N-nitrosomethylbenzylamine (NMBA) elicited a 66.7% (16/24) incidence of ESCC. With Zn-sufficiency, NMBA produced no cancers (0/21) (P<0.001). At tumor endpoint, the neoplastic ZD esophagus, as compared with Zn-sufficient esophagus, had an inflammatory gene signature with upregulation of numerous cancer-related inflammation genes (CXC and CC chemokines, chemokine receptors, cytokines and Cox-2) in addition to S100a8 and S100a9. This signature was already activated in the earlier dysplastic stage. Additionally, time-course bioinformatics analysis of expression profiles at tumor endpoint and before NMBA exposure revealed that this sustained inflammation was due to ZD rather than carcinogen exposure. Importantly, Zn replenishment reversed this inflammatory signature at both the dysplastic and neoplastic stages of ESCC development, and prevented cancer formation. Thus, the molecular definition of ZD-induced inflammation as a critical factor in ESCC development has important clinical implications with regard to development and prevention of this deadly disease.

Abstract
OBJECTIVES The expression of a receptor for advanced glycation end products (RAGE) in lesions developed during rat tongue carcinogenesis by 4-nitroquinoline 1-oxide (4-NQO) and the effect of a selective cyclooxygenase-2 inhibitor, etodolac, were investigated. METHODS The tongue lesions were induced in Fischer 344 rats given 20-30 ppm 4-NQO in their drinking water for 12 weeks and then fed the basal diet containing 150 and 300 ppm of etodolac for 16 weeks, respectively. RESULTS The incidence of carcinomas in the 4-NQO-alone group was 100%. Etodolac significantly reduced the incidences of carcinomas to 66.7% (p < 0.05) and 50% (p < 0.01) at doses of 150 and 300 ppm, respectively. RAGE protein was immunohistochemically expressed in dysplastic cells and cancer cells of dysplasias and carcinomas. Etodolac significantly decreased the stainability of RAGE protein in dysplasias (p < 0.02) and carcinomas (p < 0.01). The expression of RAGE mRNA analyzed by RT-PCR was clearly detected in carcinomas developing in the 4-NQO-alone group. In carcinomas developing in the etodolac-treated group, RAGE mRNA expression significantly decreased (p < 0.03). CONCLUSIONS These results indicate that RAGE is involved in rat tongue carcinogenesis by 4-NQO and suggest that the chemopreventive effect exerted by etodolac is partly related to the inhibition of RAGE expression.

Abstract
Human oral cancer is the sixth largest group of malignancies worldwide and single largest group of malignancies in the Indian subcontinent. Seventy percent of premalignant cancers appear from premalignant lesions. Only 8-10% of these lesions finally turn into malignancy. The appearance of these premalignant lesions is one distinct feature of human oral cancer. At present there is dearth of biomarkers to identify which of these lesions will turn into malignancy. Regional lymph node metastasis and locoregional recurrence are the major factors responsible for the limited survival of patients with oral cancer. Paucity of early diagnostic and prognostic markers is one of the contributory factors for higher mortality rates. Cancer is a multistep process and because of constrain in availability of human tissues from multiple stages of oral carcinogenesis including normal tissues, animal models are being widely used, aiming for the development of diagnostic and prognostic markers. A number of chemical carcinogens like coal tar, 20 methyl cholanthrene (20MC), 9,10-dimethyl-1,2-benzanthracene (DMBA) and 4-nitroquinoline-1-oxide (4NQO) have been used in experimental oral carcinogenesis. However, 4NQO is the preferred carcinogen apart from DMBA in the development of experimental oral carcinogenesis. 4NQO is a water soluble carcinogen, which induces tumors predominantly in the oral cavity. It produces all the stages of oral carcinogenesis and several lines of evidences suggest that similar histological as well as molecular changes are observed in the human system. In the present review an attempt has been made to collate the information available on mechanisms of action of 4NQO, studies carried out for the development of biomarkers and chemopreventives agents using 4NQO animal models.

Abstract
Understanding the complex histological, genetic and molecular changes that lead to malignant transformation of squamous epithelia of the head and neck will likely guide the development of methods for improved diagnosis, monitoring and treatment of head and neck squamous cell carcinoma (HNSCC). The development and use of animal models that closely mimic the histopathology and molecular pathogenesis of HNSCC in humans would greatly expand the research possibilities and provide a means of testing potential therapeutic agents. However, many available animal models of HNSCC fall short of this objective. In order for investigators to select the appropriate model to answer scientific questions, it is important to understand the benefits and limitations of available animal models for the study of HNSCC. The purpose of this work is to give an overview of the most pertinent animal models of HNSCC, and to discuss future directions of research in this field.
