Circ_0001742 promotes tongue squamous cell carcinoma progression via miR-431-5p/ATF3 axis

OBJECTIVE: Circular RNAs (circRNAs) have been demonstrated to involve in the development of various cancers. This study aimed to investigate the functions of circ_0001742 on regulating tongue squamous cell carcinoma (TSCC) development and the underlying mechanisms. PATIENTS AND METHODS: The expression of circ_0001742, miR-431-5p and activating transcription factor 3 (ATF3) mRNA was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The protein levels of epithelial-mesenchymal transition (EMT)-related proteins and ATF3 were measured by Western blot analysis. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and flow cytometry assay were used to evaluate cell proliferation and apoptosis. Besides. Cell migration and invasion were assessed by transwell assay. The relationships between circ_0001742 and miR-431-5p, miR-431-5p and ATF3 were predicted by online software and confirmed by dual-luciferase reporter assay. RNA immunoprecipitation (RIP), and pull-down assay. RESULTS: The expression of circ_0001742 was upregulated in TSCC tissues and cells. Knockdown of circ_0001742 inhibited proliferation, migration, invasion and EMT and induced apoptosis in TSCC cells. Then, miR-431-5p was identified as a target of circ_0001742. and knockdown of miR-431-5p reversed the effects of circ_0001742 knockdown on proliferation, apoptosis, migration, invasion and EMT of TSCC cells. Moreover. miR-431-5p could bind to ATF3. and overexpression of ATF3 rescued the effects mediated by miR-431-5p in TSCC cells. In addition. circ_0001742 regulated ATF3 expression through miR-431-5p. CONCLUSIONS: Our results demonstrated that circ_0001742 plays a tumor-promoting effect in TSCC cells by serving as a competing endogenous RNA (ceRNA) to regulate miR-431-5p/ATF3 axis, which might provide a potential therapeutic target for TSCC.

The important role of 1575-37-7

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1575-37-7, its application will become more common.

Some common heterocyclic compound, 1575-37-7, name is 4-Bromobenzene-1,2-diamine, molecular formula is C6H7BrN2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. 1575-37-7

General procedure: A solution of 10 mmol of the appropriate benzene-1,2-diamine in3.5 mL of acetic acid (AcOH) and 1 mL of water was cooled to 0-5 C,followed by the addition of 15 mmol of sodium nitrite in 2 mL ofwater. The mixture was stirred for 2 h at room temperature. Afterthe completion of the reaction, a solventwas evaporated and the residuewasco-evaporatedwith toluene (3 ¡Á 20mL). The crude productwas partitioned between water (20 mL) and ethyl acetate (20 mL),the organic phase was washed with the saturated solution of sodiumhydrogen carbonate and dried overmagnesiumsulfate (MgSO4). Theproducts were purified by crystallization from nitromethane and/orby column chromatography on silica gel using a chloroform – methanol97:3-95:5 v/v mixture as eluent. Reaction products were analyzedby use of mass-spectrometry (Waters Q-TOF Premier MassSpectrometer) and NMR spectroscopy (Varian INOVA 500 Spectrometer,see Supp. Fig. 1). Purity of the products was assessed using internalstandard quantitative NMR method (qNMR) [49]. It shouldbe noted that the formal qNMR-derived purity determined for 4-BrBt, 4-ClBt, 5,6-Cl2Bt and 5,6-Br2Bt increased significantly upon additiona small amount of water to the DMSO solution, which increasedproton exchange rates. This observation indicates that thenuclear relaxation process accompanying protomeric equilibrium(generally N1-H and N3-H forms predominates) significantly contributeto the obtained NMR spectra, the best proof of which is thestrong broadening of the H-7 resonance line in 4-BrBt and 4-ClBt(Supp. Fig. 1A,B).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1575-37-7, its application will become more common.
