Aim To detect the expression of nerve growth factor （NGF） and vascular endothelial growth factor （VEGF） in salivary adenoid cystic carcinoma （SACC） tissues, as well as to determine the correlation between growth factor expression and prognosis in SACC. Methodology Medical records of 63 patients surgically treated for SACC between January 1988 and October 2005 were reviewed. Immunohistochemistry was performed to examine the expression of NGF and VEGF in tumor tissues. Kaplan-Meier analysis and Cox＇s proportional hazard regression model were applied to assess predictors of survival. Results NGF and VEGF were overexpressed in SACC tissues, compared with those in normal salivary tissues （P〈0.05）, and the staining intensity of these two factors was stronger in groups of solid subtype, advanced TNM stage, perineural invasion and recurrence. Patients with high- expression of NGF and VEGF, solid subtype, advanced stage, perineural invasion, recurrence and extended resection alone had worse survival rates （P〈0.05）. Conclusion NGF and VEGF are expressed increasingly in the tissues of SACC cases with invasion and metastasis. NGF expression and VEGF expression are independent prognosis factors for survival.

Objective： To investigate the expression of epidermal growth factor receptor, a receptor tyrosine protein kinase, in the subcellular fractions of human salivary adenoid cystic carcinoma cell lines SACC-83 and SACC-LM. Methods： Low metastatic and high metastatic cells of the adenoid cystic carcinoma, SACC-83 and SACC-LM, were cultured. Their subcellular fractions were extracted. The expression of epidermal growth factor receptor was detected with Western blot method, and the results of protein expression were quantitatively analyzed by FluorChem V2.0 software. Results： The results of Western blot analysis indicated that, EGFR expression on the membrane of SACC-83 cells was significantly higher than that of SACC-LM cells, but its expression in cytoplasm was significantly less in the former than the later （P〈0.01）. In SACC-83 cell line, EGFR was over-expressed in membrane （P〈0.01）, but in SACC-LM cell line, EGFR was over-expressed in cytoplasm （P〈0.01）. Conclusion： The results suggest that the obtaining of metastasis ability is related to the high expression of EGFR protein in cytoplasm, so the molecular targeting therapy to EGFR may be an ideal treatment for the invasion and metastasis of salivary adenoid cystic carcinoma.

Objectives: To investigate the relation between metastatic potential of salivary adenoid cystic carcinoma (SACC) and tumor cell-platelet adhesion, and the antimetastatic effect of integrin IIb/IIIa inhibitor on SACC. Methods: Tumor cell-platelet adhesion of highly metastatic SACC-LM, non-highly metastatic SACC-83 and effect of aspirin, arginine-aspartate (RD), magnesium acetylsalicylate on adhesion were studiedin vitro. Antimetastafic effect of aspirin, RD, magnesium acetysalicylate on experimental metastasis of SACC was observedin vivo. Results: The tumor cell-platelet adhesion was stronger in SACC-LM than in SACC-83. Aspirin, RD and magnesium acetylsalicylate could inhibit the adhesion of SACC-LM at the concentration of 1, 5 and 25 μg/ml. RD can inhibit experimental metastasis of SACC. Conclusion: Metastasis of SACC is related to platelet-tumor cell adhesion, RD could inhibit metastasis of SACC.

Background A20, also known as tumor necrosis factor α induced protein 3 （TNFaip3）, is a cytoplasmic zinc finger protein that inhibits nuclear factor kappa-B （NF-κB） activity and prevents tumor necrosis factor （TNF）-mediated programmed cell death. NF-κB is a transcription factor that regulates expression of genes involved in cell proliferation, cell survival and anti-apoptosis. Several studies have implicated that the NF-κB signal pathway is associated with angiogenesis and clinico-pathological process of adenoid cystic carcinoma （ACC） of the salivary glands.Methods The ability of overexpression of A2.0 to influence the biological behavior and invasion of ACC cells was examined. The cells were stably transfected with full-length A20 cDNA. Stable gene transfer was verified by realtime-polymerase chain reaction （PCR） and Western blot analysis. The change of cell biological behavior was examined by methyl thiazolyl tetrazolium （MTT） and NF-κB luciferase reporter assay and the invasion of the cells was examined by a Matrigel invasion chamber.Results pEGPFN3-A2.0 gene was stably transferred into ACC-2 cells and overexpressed. When cells were treated with TNFα, the NF-κB activity of ACC-2-A20 cells could be down-regulated about 46.32% in contrast to ACC-2-GFP cells （P〈0.05）. A20 potently inhibited growth of A20 transfectant ACC-2-A20 compared with control vector transfected groups and the ACC-2 empty control group （P〈0.05）. The ACC-2-A20 cells showed significantly reduced ability to invade through Matdgei-coated filters compared to ACC-2-GFP and ACC-2 cells. The inhibition rate was up to 71.05% （P〈0.05）. Conclusions A2.0 gene transfer is associated with decreased tumor invasion, in part via the down-regulation of NF-κB expression, providing evidence for a potential application of A20 in designing a treatment modality for salivary gland cancers such as ACC.

Purpose/Background : Autophagy was proved to be involved in tumor progression and chemo-radiotherapy resistance. Chloroquine(CQ), an autophagy inhibitor, can increase chemo-radiotherapy sensitivity in several cancer cells. However, the correlation between CQ and chemotherapy sensitive in salivary adenoid cystic carcinoma(ACC) remains obscure.

Purpose/Background:Neurotropic infiltrative growth and distant metastasis are the main causes of death in salivary adenoid cystic carcinoma(SACC) patients. Long noncoding RNAs(lncRNAs) are involved in many human neoplasms, however, their potential roles in SACC are *** and Methods:We screen the expression profile of lncRNAs in two SACC cells(SACC-83 and SACC-LM) via RNA-sequencing. In situ hybridization and RT-qPCR were used to determine the level and prognostic values of ADAMTS9-AS2 in SACC tissues. Then, functional experiments in vitro and in vivo were performed to investigate the effects of ADAMTS9-AS2 on tumor growth, metastasis in SACC. Mechanistically, RT-qPCR, dual luciferase reporter assay RNA pull-down and RNA immunoprecipitation experiments were performed to confirm the interaction between ADAMTS9-AS2 and miR-143-3p in SACC cells.

目的:肿瘤血管内皮细胞(tumor-derived endothelial cells, TDECs)在多种恶性肿瘤中发挥重要作用,但在涎腺腺样囊性癌(salivaryadenoidcystic carcinoma, SACC)中尚未见相关报道。本研究将探究SACC相关TDECs的生物学特性。方法:(1)采用Transwell将人真皮微血管内皮细胞(human dermal microvascular endothelial cells, HDMECs)与SACC细胞(ACC-2和ACC-M)共培养,以TEM-8为标记物鉴定TDECs;(2)采用CCK-8实验、划痕实验、Factin染色等检测TDECs生物学特性的改变。结果:(1)体外Transwell共培养诱导的TDECs呈TEM-8阳性表达;(2)TDECs的细胞增殖能力、迁移能力增强,并均有统计学差异(P <0.05);(3)TDECs中F-actin细胞骨架免疫荧光染色的表达显著强于HDMECs。结论:SACC细胞体外共培养诱导的TDECs具有较为特异的生物学行为,具有成为SACC抗血管治疗新靶点的潜能。
