目的 通过多种生物信息学方法分析MAML1在GC患者中的表达及与临床特征、预后和免疫治疗疗效的相关性。方法 利用TCGA数据库分析胃癌组织与正常胃黏膜组织中的MAML1表达水平;Kaplan-Meier在线工具对胃癌数据集GSE15459进行分析,阐明MAML1与患者临床特征及分期、治疗疗效的相关性;STRING软件预测与MAML1表达相关的基因,并用FUNRICH软件评估其富集的分子生物学功能和信号通路;TIMER和GEPIA数据库探索MAML1表达水平与肿瘤浸润免疫细胞及其相应基因标记集之间的关系。结果 MAML1在GC组织中的表达水平高于正常组织(P<0.001),且其表达水平与III期、有淋巴结转移、无远处转移的患者生存期相关(P<0.05),而与I、II和IV期、无淋巴结转移和有远处转移的患者生存期无相关性(P>0.05)。MAML1的相关作用基因主要分布在细胞核、参与转录调控,并且主要富集在雄激素受体、C-MYB转录因子和HIF-2α转录调控等相关的信号通路。MAML1表达水平与B细胞、CD4⁺ T细胞、巨噬细胞的表达水平存在正相关关系(P<0.05),但与肿瘤纯度、CD8⁺ T细胞、中性粒细胞、树突状细胞无相关性(P>0.05)。结论 MAML1有可能成为GC患者较差的临床预后标志物之一,其潜在分子机制可能与转录调控调节肿瘤微环境有关。

Objective To investigate the expression of MAML1 and its relationship with clinical characteristics, prognosis and the efficiency of immunotherapy in patients with GC. Methods MAML1 expression profile was observed by TCGA database. Kaplan-Meier survival analysis was applied to evaluate the correlation between the expression of MAML1 and clinical characteristics, prognosis and treatment efficiency of patients in GSE15459 dataset. MAML1-associated genes were predicted by STRING and were enriched in GO and KEGG by FUNRICH software. The relationship between MAML1 expression and markers of tumor infiltrated cells were explored by TIMER and GEPIA database. Results MAML1 was abnormally upregulated in GC tissues compared to normal gastric tissues (P<0.001). MAML1 expression was significantly associated with the overall survival of patients in stage III, with lymph node metastasis and without distant metastasis (P<0.001). There was no significant difference between MAML1 expression and the overall survival of patients in stage I, II, IV, without lymph node metastasis and with distant metastasis (P>0.05). MAML1-assoicated genes were mainly located at the nucleus, mediating transcriptional regulation and mainly enriching in androgen receptor, C-MYB transcription factor and HIF-2α transcription regulation and other related signaling pathways. MAML1 expression was positively related with the expression of B cell, CD4⁺ T cell and macrophages (P<0.05), but without significant difference with tumor purity, CD8⁺ T cell, neutrophils and dendritic cells (P>0.05). Conclusions MAML1 could be used as a marker of clinical prognosis of patients with GC. The potential molecular mechanism might be associated with its function in transcriptional regulation and changes in tumor microenvironment.

Objective In this study, GEPIA database, including TCGA database and GTEx database, were used to explore the potential targets of dihydrotanshinone I on gastric cancer through oxidative stress. Methods Literatures on potential targets of dihydrotanshinone I in gastric cancer were searched in the database;GEPIA database tool was used to analyze the potential mechanism of dihydrotanshinone I on gastric cancer;taking analysis of the correlation between potential target genes and genes expressing key antioxidant stress proteins;We had analysis of expression level of dihydrotanshinone I on potential target genes in gastric cancer patients;and prognostic analysis of dihydrotanshinone I on potential target genes in gastric cancer patients. Results The main targeting genes(proteins) of dihydrotanshinone I on potential target genes were hypoxia inducible factor-1(hif-1) and citrulline histone H3(CITH3), whose genes were HIF1 A and NOS2, respectively;GEPIA database showed that there was a positive correlation between HIF1 A and CAT(P=2e-04, R=0.18), GPX1(P=0.033, R=0.11), or NFE2L2(P=0, R=0.41), while NOS2 only had a positive correlation with SOD1(P=0.21, R=0.18), and no correlation with other three genes. The expression levels of HIF1 A and NOS2 in gastric cancer tissues were higher than those in normal adjacent gastric tissues. The overall survival rate of patients with gastric cancer decreased with the high expression of HIF1 A. Conclusion Dihydrotanshinone I may induce apoptosis of AGS cells through reactive oxygen species mediated oxidative stress, and inhibit the expression of HIF1 A and NOS2, thus inhibit their antioxidative stress, which may improve the overall survival rate of gastric cancer patients.

Objective To evaluate the anticancer actions of dihydrotanshinone Ⅰ(DHTS)in gastric cancer cells. Methods Cell viability was determined using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)assay. Intracellular reactive oxygen species (ROS)levels were determined using flow cytometry. Caspase activities were measured with fluorometric assay. The anticancer activity of DHTS in nude mouse gastric cancer model was verified. Results MTT assay showed that DHTS greatly inhibited HCG27 or AGS cell viability in dose- and time-dependent manners. Elevated intracellular ROS levels and increased apoptotic cells were observed in DHTS-treated HCG27 or AGS cells. In addition, activation of caspase-3 and caspase-8, rather than caspase-9, were noticed in DHTS-treated HCG27 or AGS cells. Furthermore, blocking ROS generation with N-acetylcysteine markedly reversed DHTS-induced cell apoptosis. DHTS inhibited the increase of tumor volume in mice. Conclusion All the findings strongly suggest that DHTS may initiate ROS generation and induce oxidative stress and cell apoptosis in HCG27 or AGS human gastric cancer cells, which deserves to be further developed as an anticancer agent.

Objective To investigate the expression and clinical significance of Sonic hedgehog(Shh), Glioma-associated oncogene homolog -1(Gli-1) and Matrix metalloproteinase-2(MMP-2) in gastric cancer.Shh and Gli-1 are the molecules of Hedgehog(Hh) signaling pathway. MMP-2 is the member of matrix metalloproteinase family. Methods The expression of Shh,Gli-1 and MMP-2 proteins was examined by immunohistochemistry in the human gastric cancer tissues and the human gastric polyp and the normal gastric mucosa tissues of 40 cases. Results The positive expression rates of Shh,Gli-1 and MMP-2 in gastric cancer were 62.5%,67.5% and 72.5% respectively, which were significantly higher than those in the gastric polyp tissues (the positive expression rates were 27.5%,37.5% and 32.5% respectively) and normal gastric mucosa tissues (the positive expression rates were 22.5%,17.5% and 12.5% respectively),P<0.05.The expression of Shh,Gli-1 and MMP-2 was not correlated with the sex,age or histological type(P>0.05),but was correlated with depth of invasion,differentiation level and lymphonode metastasis in gastric cancer(P<0.05). The expression of Shh and Gli-1 was positive correlated with MMP-2. Conclusion Hedgehog(Hh)signaling pathway may have great effects on enhancing the invasive ability of gastric cancer by upregulating MMP-2 protein through some unknown mechanisms.The combined detection of the expression level of Shh,Gli-1 and MMP-2 in gastric cancer tissues might be used as an Objective references for assessing the prognosis of gastric cancer.
