Zhang X, Zhuang R. Dione-thiophene conjugate inhibits proliferation and metastasis of nasopharyngeal carcinoma cells through calcium binding protein-P down-regulation. Eur J Med Chem 2019; 168:199-206. [PMID: 30822709 DOI: 10.1016/j.ejmech.2019.01.051] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Revised: 01/17/2019] [Accepted: 01/18/2019] [Indexed: 11/30/2022]
Abstract
In the present study a series of dione-thiophenol conjugates was prepared and evaluated against nasopharyngeal carcinoma (NPC) cells. MTT assay showed that compound 4a reduced proliferation of C666-1 and CNE-1 cells to 26 and 24%, respectively at 10 μmol/l concentration. Flow cytometry revealed that increasing the concentration of compound 4a from 2 to 10 μmol/l increased the proportion of early apoptotic C666-1 cells from 2.76 to 69.43%. A significant (P < 0.001) decrease in the expression of S100P was caused by compound 4a. In compound 4a treated C666-1 cells the expression of RAGE, EGFR, CD44, MMP2 and MMP9 was markedly decreased. In summary, compound 4a inhibits nasopharyngeal cancer cell proliferation and induces apoptosis through down-regulation of S100P. Moreover, compound 4a also decreases MMP-2, MMP-9, EGFR, CD44 and RAGE expression in nasopharyngeal cancer cells. Thus, compound 4a can be investigated further as a drug candidate for the treatment of nasopharyngeal cancer.

Abstract
In the present study, the function of S100 calcium binding protein P (S100P) in the C666-1 nasopharyngeal carcinoma (NPC) cell line was examined. The levels of S100P protein in NPC tissues were analyzed using immunohistochemistry, and small interfering RNA silenced S100P expression in C666-1 cells. Subsequently, cell proliferation, colony formation, migration and wound-healing assays were performed in order to assess whether the knockdown of S100P was able to influence the biological behavior of C666-1 cells. The expression levels of the receptor for advanced glycation end products (RAGE) were analyzed using a western blot following the inhibition of S100P. The immunohistochemistry results revealed that S100P was elevated in expression in 45/78 (57.7%) of patients with NPC, as compared with 5/30 (16.7%) of patients with benign inflammation. The S100P protein levels correlated with the rates of proliferation and migration in C666-1 cells. Additionally, reduced S100P expression levels altered a series of intracellular events, including the downregulation of epidermal growth factor receptor, cluster of differentiation (CD) 44, matrix metalloproteinase (MMP) 2 and MMP9 protein expression. In addition, RAGE expression was downregulated in the S100P silenced C666-1 cells, as detected by western blot analysis. These data suggest that S100P is important during the development and progression of nasopharyngeal cancer. Therefore, S100P may provide a novel treatment target for NPC.

Abstract
Nucleolar organizer regions (NORs) were studied in surgically removed specimens from 76 patients with squamous cell carcinomas of the larynx using an argyrophilic (Ag) staining technique. The mean number of AgNORs per nucleus was 4.3 +/- 1.38 (SD). The mean AgNOR number for T1 or T2 disease was statistically lower than that for T3 or T4 lesions (P < 0.05). The mean AgNOR number was lower in patients with N0 disease than in patients with N1 or N2 or N3 tumors (P < 0.05). There was also a statistically significant difference between the mean AgNOR number for stage II and stage III disease (P < 0.01), for stage III and stage IV disease (P < 0.05), but not for stage I and stage II disease. According to the histological grading, there was a significant difference between the mean AgNOR number for the well-differentiated and moderately differentiated tumors (P < 0.05), and for the moderately differentiated and poorly differentiated types (P < 0.01). These results suggest that the number of AgNORs in the nucleus is a significant indicator of laryngeal carcinomas.

Abstract
The accurate determination of levels of differentiation is of prognostic value in human head and neck squamous cell carcinomas (HNSCCs). Because the deliberate selection of biochemical determinants accompanying certain stages of differentiation can refine the predictive power of histochemical assessments, the application of the quantitative evaluation of staining distribution and intensity by computer-assisted microscopy is one prerequisite to potential improvements. We used 2 innovative approaches with peanut agglutinin based on encouraging results with respect to common lectin-histochemistry. First, we used a custom-made neoglycoprotein to monitor the presence of Thomsen-Friedenreich (T) antigen-binding sites. Second, we measured the presence of 2 galectins immunohistochemically and, at the same time, measured lectin-histochemically the presence of accessible ligands for the endogenous lectins. We also monitored the presence of calcyclin, a protein with relevance to cell cycle progression or exocytosis. With 61 cases of HNSCC as their basis, including 31 oral, 20 laryngeal, and 10 hypopharyngeal lesions, the data show that the main modifications observed in connection with a loss of differentiation are related to a modification in the levels of both galectin-3/galectin-3-binding site and T-antigen/T-antigen-binding site expressions. The data obtained also suggest that galectin-3 could act as an acceptor site for the T antigen. Because the level of differentiation is known to be indicative of the recurrence rate in HNSCCs and our data clearly indicate that galectin-3 and the T antigen (and their respective binding sites) are involved in dedifferentiation processes, further investigation is warranted into the roles of galectins in HNSCC tumor progression and recurrence analysis.

Abstract
Recent studies have identified that mucin antigens and Lewis X (Lex)-related antigens behave like oncodevelopmental tumor-associated antigens in several human adenocarcinomas. However, the expression of these antigens in pharyngeal and laryngeal squamous cell carcinomas (SCC) and in the precursor lesion is not fully elucidated yet. In the present study, the expression of mucin core protein antigens associated with the MUC1 gene product (DF3 antigen, mammary-type apomucin) and the MUC2 gene product (intestinal-MRP antigen, intestinal-type apomucin) mucin carbohydrate antigens that are associated with the earliest steps in mucin glycosylation (Tn, sialyl-Tn and T), and Lex-related antigens (Lex, Ley and sialyl Lex-i) in biopsy or resected specimens from 26 normal squamous epithelia (NSE), 49 dysplastic squamous epithelia (DSE) and 51 SCC were examined. The DF3 antigen was not expressed in NSE (0%), whereas it was expressed in 20 DSE (41%) and in 31 SCC (61%). The intestinal-MRP antigen showed no expression in NSE, DSE or SCC. The Tn antigen showed no expression in NSE, but showed low expression rates in DSE (14%) and in SCC (16%). The sialyl-Tn and T antigens were expressed in NSE, as well as in DSE and SCC. The T antigen expression increased with progression from NSE to DSE to SCC, while the sialyl-Tn antigen did not show such a tendency. Any of the three Lex-related antigens showed no characteristic expression in DSE and SCC. In the eight antigens examined, only DF3 antigen was an effective marker for DSE and SCC in the pharyngeal and laryngeal region. Cytoplasmic expression of DF3 and sialyl-Tn antigens were more frequently seen in SCC than in DSE, and might be useful to differentiate SCC from DSE.

In vivo infiltration of mononuclear cells in squamous cell carcinoma of the head and neck correlates with the ability to expand tumour-infiltrating T cells in vitro and with the expression of MHC class I antigens on tumour cells.

Abstract
A series of 18 head and neck squamous cell carcinoma biopsies, 6 primary and 12 recurrent, were investigated for tumour-infiltrating mononuclear cells with monoclonal or polyclonal antibodies. Our results suggest that the number of T cells at the tumour edge in vivo correlates well with their ability to expand in vitro in the presence of high-dose interleukin-2 (2000 U/ml). High MHC class I antigen expression on tumour cells was found to be positively correlated with p53 overexpression, suggesting that p53-derived peptides, wild-type or mutated ones, presented by MHC class I antigens, are potential targets for MHC-restricted cytotoxic T cells in head and neck squamous cell carcinomas. However, lack of correlation between peritumoural T cell infiltration in vivo and T cell expansion in vitro, on the one hand, and p53 overexpression on tumour cells, on the other hand, suggests absence of p53-peptide-specific T cells in the patients. Eight out of ten expanded tumour-infiltrating lymphocyte (TIL) cultures showed T-cell-mediated cytotoxicity. "Promiscuous" cytotoxic T cell activity against the natural-killer-cell-sensitive K562 target cell line was observed in three out of ten TIL expansion cultures.
