整合素在许多肿瘤细胞中高表达,并且参与肿瘤细胞的侵袭转移。在肝细胞癌中,整合素β1被报导高表达,并促进肿瘤细胞的侵袭。目前,对于整合素的表达调控癌细胞机制以及干预其表达进而抑制肿瘤细胞转移的研究较少。本研究探讨利用小分子化合物抑制整合素表达来抑制肿瘤细胞迁移和侵袭的可能。首先,对临床肝癌细胞患者癌组织和癌旁组织中的整合素β1的表达进行检测,发现其在癌组织中的表达显著高于癌旁组织(P<0.05)。对TCGA肿瘤数据库的生物信息学分析结果同样显示,整合素β1的高表达与肝癌的分期(P=0.019)和预后(P=0.013)相关。通过筛选发现,苯胺嘧啶衍生物X09可以抑制肝癌细胞中整合素β1的mRNA和蛋白质的表达(P<0.01)。细胞划痕愈合实验和细胞穿孔实验结果显示,苯胺嘧啶衍生物X-9能够抑制肝癌细胞的迁移和侵袭(P<0.01)。进一步的研究证实,在肝癌细胞中外源表达整合素β1可以逆转X-9对肝癌细胞迁移和侵袭的抑制;而在敲低整合素β1的细胞中,X-9对细胞的迁移和侵袭的抑制被消除。因此,鉴定出苯胺嘧啶衍生物X-9可以通过下调整合素β1表达,进而抑制肝癌细胞的迁移和侵袭。 相似文献

Extensive evidence indicate that long noncoding RNAs (lncRNAs) regulates the tumorigenesis and progression of hepatocellular carcinoma (HCC). However, the expression and biological function of lncRNA A1BG antisense RNA 1 (A1BG-AS1) were poorly known in HCC. Here, we found the underexpression of A1BG-AS1 in HCC via analysis of The Cancer Genome Atlas database. Further analyses confirmed that A1BG-AS1 expression in HCC was markedly lower than that in noncancerous tissues based on our HCC cohort. Clinical association analysis revealed that low A1BG-AS1 expression correlated with poor prognostic features, such as microvascular invasion, high tumor grade, and advanced tumor stage. Follow-up data indicated that low A1BG-AS1 level evidently correlated with poor clinical outcomes of HCC patients. Moreover, forced expression of A1BG-AS1 repressed proliferation, migration, and invasion of HCC cells in vitro. Conversely, A1BG-AS1 knockdown promoted these malignant behaviors in HepG2 cells. Mechanistically, A1BG-AS1 functioned as a competing endogenous RNA by directly sponging miR-216a-5p in HCC cells. Notably, miR-216a-5p restoration rescued A1BG-AS1 attenuated proliferation, migration and invasion of HCCLM3 cells. A1BG-AS1 positively regulated the levels of phosphatase and tensin homolog and SMAD family member 7, which were reduced by miR-216a-5p in HCC cells. Altogether, we conclude that A1BG-AS1 exerts a tumor suppressive role in HCC progression. 相似文献

Emerging studies have indicated that long noncoding RNAs (lncRNAs) possess various functions in initiating human cancers. However, the role of lncRNAs in hepatocellular carcinoma (HCC) still remains ill understood. In this study, we sought to investigate the role of lncRNA CACNA1G-AS1 in HCC progression. Through bioinformatics analysis, we found that CACNA1G-AS1 expression was significantly upregulated in HCC tissues compared with that in the adjacent normal tissues. Moreover, CACNA1G-AS1 upregulation indicated poor prognosis in HCC patients. Knockdown of CACNA1G-AS1 attenuated the proliferation, migration, and invasion of HCC cells. Additionally, decreased expression of CACNA1G-AS1 prevented epithelial–mesenchymal transition. In vivo assay also showed that CACNA1G-AS1 silencing HCC cells have smaller tumor volumes and weights. Further investigations demonstrated that CACNA1G-AS1 worked as a competing endogenous RNA to bind microRNA-2392 (miR-2392) and thereby alleviate the repression of the downstream target C1orf61. Collectively, CACNA1G-AS1 promotes HCC progression through regulating the miR-2392/C1orf61 pathway. 相似文献

Long non-coding RNAs (lncRNAs) are crucial regulators of tumorigenesis and progression in human cancer, including hepatocellular carcinoma (HCC). However, the role of most lncRNAs that are dysregulated in HCC remains to be elucidated. Here, we investigated the role of OSER1-AS1 in the progression of HCC. The results of database and qRT-PCR analysis demonstrated that OSER1-AS1 was highly expressed in HCC tissues and the high expression of OSER1-AS1 was closely associated with larger tumor size, advanced tumor stages, lower disease free survival and overall survival of HCC patients. OSER1-AS1 knockdown significantly inhibited the proliferation, invasion and migration of HCC cells, and induced the apoptosis. In addition, the dual luciferase reporter assay directly demonstrated that OSER1-AS1 functioned as a molecular sponge for miR-372-3p to promote Rab23 expression. Moreover, the results of immunohistochemistry and western blot analysis showed that Rab23 was highly expressed in HCC tissues, and the high expression of Rab23 was closely associated with the poor overall survival of HCC patients. Immunofluorescence assay also found the subcellular localization of Rab23 in HCC cells. Rab23 was obviously downregulated in cells that were transfected with miR-372-3p mimics. MiR-372-3p mimics significantly inhibited the proliferation and invasion of HCC cells). Rab23 restoration partially reversed miR-372-3p-induced tumor suppressive effects on HCC cells. In conclusion, we found that OSER1-AS1 acted as a ceRNA to sponge miR-372-3p, thereby positively regulating the Rab23 expression and ultimately acting as a tumor suppressor gene in HCC progression. 相似文献

Caveolin-1 (Cav-1) has been recently identified to be over-expressed in hepatocellular carcinoma (HCC) and promote HCC cell motility and invasion ability via inducing epithelial-mesenchymal transition (EMT). However, the mechanism of aberrant overexpression of Cav-1 remains vague. Here, we observed that Cav-1 expression was positively associated with GLI1 expression in HCC tissues. Forced expression of GLI1 up-regulated Cav-1 in Huh7 cells, while knockdown of GLI1 decreased expression of Cav-1 in SNU449 cells. Additionally, silencing Cav-1 abolished GLI1-induced EMT of Huh7 cells. The correlation between GLI1 and Cav-1 was confirmed in tumor specimens from HCC patients and Cav-1 was found to be associated with poor prognosis after hepatic resection. The relationship between protein expression of GLI1 and Cav-1 was also established in HCC xenografts of nude mice. These results suggest that GLI1 may be attributed to Cav-1 up-regulation which plays an important role in GLI1-driven EMT phenotype in HCC. 相似文献

Dysregulation of microRNAs (miRNAs) is actively involved in the pathogenesis and tumorigenicity of hepatocellular carcinoma (HCC). miR-489 was found to play either oncogenic or tumor suppressive roles in human cancers. Recent study reported that the levels of miR-489 in late recurrent HCC patients were evidently higher than that in early recurrent cases, suggesting that miR-489 may function as a tumor suppressive miRNA in HCC. Yet, the clinical value and biological function of miR-489 remain rarely known in HCC. Here, we presented that miR-489 level in HCC tissues was notably reduced compared to matched non-cancerous specimens. Its decreased level was evidently correlated with adverse clinical parameters and poor prognosis of HCC patients. Accordingly, the levels of miR-489 were obviously down-regulated in HCC cells. Ectopic expression of miR-489 in HCCLM3 and MHCC97H cells prominently inhibits the migration and invasion of tumor cells and reduced lung metastases in vivo, while miR-489 knockdown increased these behaviors of HepG2 and MHCC97L cells. Mechanically, miR-489 negatively regulated matrix metalloproteinase-7 (MMP7) abundance in HCC cells. Herein, MMP7 was found to be a downstream molecule of miR-489 in HCC. An inversely correlation between miR-489 and MMP7 was confirmed in HCC specimens. MMP7 knockdown prohibited cell migration and invasion while MMP7 overexpression showed opposite effects on HCC cells. Furthermore, restoration of MMP7 expression could abrogate the anti-metastatic effects of miR-489 on HCCLM3 cells with enhanced cell migration and invasion. Altogether, miR-489 potentially acts as a prognostic predictor and a drug-target for HCC patients. 相似文献

Background
F-box only protein 8 (FBX8), a novel component of F-box proteins, is lost in several cancers and has been associated with invasiveness of cancer cells. However, its expression pattern and role in the progression of hepatocellular carcinoma remain unclear. This study investigated the prognostic significance of FBX8 in hepatocellular carcinoma samples and analyzed FBX8 function in hepatocellular carcinoma cells by gene manipulation.Methodology
The expression of FBX8 was detected in 120 cases of clinical paraffin-embedded hepatocellular carcinoma tissues, 20 matched pairs of fresh tissues and five hepatocellular carcinoma cell lines by immunohistochemistry with clinicopathological analyses, real-time RT-PCR or Western blot. The correlation of FBX8 expression with cell proliferation and invasion in five HCC cell lines was analyzed. Moreover, loss of function and gain of function assays were performed to evaluate the effect of FBX8 on cell proliferation, motility, invasion in vitro and metastasis in vivo.Conclusions
We found that FBX8 was obviously down-regulated in HCC tissues and cell lines (P<0.05). The FBX8 down-regulation correlated significantly with poor prognosis, and FBX8 status was identified as an independent significant prognostic factor. Over-expression of FBX8 decreased proliferation, migration and invasion in HepG2 and 97H cells, while knock-down of FBX8 in 7721 cells showed the opposite effect. FBX8 negatively correlated with cell proliferation and invasion in 7701, M3, HepG2 and 97H cell lines. In vivo functional assays showed FBX8 suppressed tumor growth and pulmonary metastatic potential in mice. Our results indicate that down-regulation of FBX8 significantly correlates with invasion, metastasis and poor survival in hepatocellular carcinoma patients. It may be a useful biomarker for therapeutic strategy and control in hepatocellular carcinoma treatment. 相似文献13.
Background
LZAP was isolated as a binding protein of the Cdk5 activator p35. LZAP has been highly conserved during evolution and has been shown to function as a tumor suppressor in various cancers. This study aimed to investigate LZAP expression and its prognostic value in hepatocellular carcinoma (HCC). Meanwhile, the function of LZAP in hepatocarcinogenesis was further investigated in cell culture models and mouse models.Methods
Real-time quantitative PCR, western blot and immunohistochemistry were used to explore LZAP expression in HCC cell lines and primary HCC clinical specimens. The functions of LZAP in the proliferation, colony formation, cell cycle, migration, invasion and apoptosis of HCC cell lines were also analyzed by infecting cells with an adenovirus containing full-length LZAP. The effect of LZAP on tumorigenicity in nude mice was also investigated.Results
LZAP expression was significantly decreased in the tumor tissues and HCC cell lines. Clinicopathological analysis showed that LZAP expression was significantly correlated with tumor size, histopathological classification and serum α-fetoprotein (AFP). The Kaplan–Meier survival curves revealed that decreasing LZAP expression was associated with poor prognosis in HCC patients. LZAP expression was an independent prognostic marker of overall HCC patient survival in a multivariate analysis. The re-introduction of LZAP expression in the HepG2 and sk-Hep1 HCC cell lines significantly inhibited proliferation and colony formation in the HCC cells and induced G1 phase arrest and apoptosis of the HCC cells in vitro. Restoring LZAP expression in the HCC cell lines also inhibited migration and invasion. In addition, experiments with a mouse model revealed that LZAP overexpression could suppress HCC tumorigenicity in vivo.Conclusions
Our data suggest that LZAP may play an important role in HCC progression and could be a potential molecular therapy target for HCC. 相似文献14.

Breast cancer metastasis suppressor 1 (BRMS1) was originally identified as an active metastasis suppressor in human breast cancer. Loss of BRMS1 expression correlates with tumor progression, and BRMS1 suppresses several steps required for tumor metastasis. However, the role of BRMS1 in hepatocellular carcinoma (HCC) remains elusive. In this study, we found that the expression level of BRMS1 was significantly down-regulated in HCC tissues. Expression of BRMS1 in SK-Hep1 cells did not affect cell growth under normal culture conditions, but sensitized cells to apoptosis induced by serum deprivation or anoikis. Consistently, knockdown of endogenous BRMS1 expression in Hep3B cells suppressed cell apoptosis. We identified that BRMS1 suppresses osteopontin (OPN) expression in HCC cells and that there is a negative correlation between BRMS1 and OPN mRNA expression in HCC tissues. Moreover, knockdown of endogenous OPN expression reversed the anti-apoptosis effect achieved by knockdown of BRMS1. Taken together, our results show that BRMS1 sensitizes HCC cells to apoptosis through suppressing OPN expression, suggesting a potential role of BRMS1 in regulating HCC apoptosis and metastasis. 相似文献

Hepatic stellate cells (HSCs), a specialized stromal cytotype in the liver, have been demonstrated to actively contribute to hepatocellular carcinoma (HCC) development. However, the previous studies were performed using HSC cell lines, and the prognostic value of intratumoral HSCs (tHSCs) was unclear. Here we isolated tHSCs from fresh human HCC tissues, and analyzed the abilities of tHSCs to promote HCC progression by using in vitro assays for cell viability, migration and invasion as well as epithelial-mesenchymal transition (EMT) phenotype. 252 HCC patients who underwent hepatectomy were enrolled for analysis of tHSCs and E-cadherin expression in tumor tissues, and 55 HCC patients for analysis of tHSCs in tumor tissues and circulating tumor cells (CTCs) in blood. Prognostic factors were then identified. The results showed that coculture of tHSCs with HCC cells had a stronger effect on HCC cell viability, migration and invasion, accompanied with the acquisition of epithelial-mesenchymal transition (EMT) phenotype. In vivo cotransplantation of HCC cells with tHSCs into nude mice more efficiently promoted tumor formation and growth. Icaritin, a known apoptosis inducer of HSCs, was demonstrated to effectively inhibit tHSC proliferation in vitro and tHSC-induced HCC-promoting effects in vivo. Clinical evidence indicated that tHSCs were rich in 45% of the HCC specimens, tHSC-rich subtypes were negatively correlated either with E-cadherin expression in tumor tissues (r = -0.256, p < 0.001) or with preoperative CTCs in blood (r = -0.287, p = 0.033), and were significantly correlated with tumor size (p = 0.027), TNM staging (p = 0.018), and vascular invasion (p = 0.008). Overall and recurrence-free survival rates of tHSC-rich patients were significantly worse than those for tHSC-poor patients. Multivariate analysis revealed tHSC-rich as an independent factor for overall and recurrence-free survival. In conclusion, tHSCs provide a promising prognostic biomarker and a new treatment target for HCC. 相似文献

The poor prognosis of hepatocellular carcinoma (HCC) is mainly due to the development of invasion and metastasis. Recent data strongly suggests the important role of miRNAs in cancer progression, including invasion and metastasis. Here, we found miR-217 expression was much lower in highly invasive MHCC-97H HCC cells and metastatic HCC tissues. Restored miR-217 expression with miR-217 mimics inhibited invasion of MHCC-97H cells. Inversely, miR-217 inhibition enhanced the invasive ability of Huh7 and MHCC-97L cells. Mechanically, bioinformatics analysis combined with experimental analysis demonstrated E2F3 was a novel direct target of miR-217. Moreover, E2F3 protein level was positively associated with HCC metastasis and functional analysis confirmed the positive role of E2F3 in HCC cell invasion. Our findings suggest miR-217 function as a potential tumor suppressor in HCC progression and miR-217-E2F3 axis may be a novel candidate for developing rational therapeutic strategies. 相似文献

G2 and S phase-expressed-1 (GTSE1) was recently reported to upregulate in several types of human cancer, based on negatively regulate p53 expression. However, its expression and functional roles in hepatocellular carcinoma (HCC) remain unknown. In this study, GTSE1 was observed to be highly expressed in HCC specimens and cell lines both at messenger RNA (mRNA) and protein levels. Furthermore, high GTSE1 expression was positively associated with tumor size, venous invasion, advanced tumor stage, and short overall survival. Moreover, we generated stable GTSE1 knockdown HCC cell lines to explore the effects of GTSE1 silencing on the growth and invasion of HCC in vitro. In determining the pathway through which GTSE1 regulated cell proliferation and invasion, GTSE1 silencing was found to inhibit AKT phosphorylation and downregulated cell cycle-related protein. In addition, GTSE1 downregulation decreased the growth of xenografts. In conclusion, these results indicated for the first time that overexpression of GTSE1 was involved in the progress of HCC, enhancing proliferation and promoting cell invasion in HCC cells. 相似文献

Oral squamous cell carcinoma (OSCC), the most common pathological type of oral cancer, is still a frequent malignancy with unsatisfactory prognosis. Accumulating studies have proven some microRNAs (miRNAs) can function as oncogenes in OSCC by targeting tumor suppressors. In this study, we first investigated the expression and role of tumor suppressor bridging integrator-1 (BIN1) in OSCC tissues and cells. Our results indicated that BIN1 was low expressed in the OSCC tissues and cell lines (SCC6, SCC9, SCC25, HN4, and HN6) along with miR-211 was highly expressed in OSCC tissues and cell lines, and BIN1 overexpression could evidently inhibit their proliferation, migration, and invasion abilities. Next, we used bioinformation algorithms to predict the potential miRNA targeting BIN1 and chose miR-211 for further study. miR-211, a highly expressed miRNA in OSCC cells, could specifically bind with the 3′-untranslated region (3′-UTR) of BIN1 to trigger its degradation. Addition of miR-211 inhibitor could evidently suppress the malignant behaviors of OSCC cells by upregulating BIN1 expression and inhibit the activation of the EGFR/MAPK pathway. Taken together the findings of the study indicated that miR-211 mediated BIN1 downregulation had crucial significances in OSCC, suggesting the miR-211 might be a novel potential therapeutic target for the OSCC treatment. 相似文献

Ras converting enzyme 1 (Rce1) plays an important role in invasion and metastasis of malignancy. However, the mechanism has not yet been fully explored in hepatocellular carcinoma (HCC). Primarily, we investigated the expression of Rce1 and H-Ras influence on patient prognosis through the clinical data. Further, we analyzed the regulatory effects of Rce1/H-Ras signal pathway on the epithelial–mesenchymal transition (EMT) in vitro and in vivo. Finally, we screened out the protein which bonds with Rce1 by CO-IP experiment to discuss the mechanism of Rce1 in EMT of HCC. This research revealed a significantly decreased expression of Rce1 in HCC compared with noncancerous tissues (p < .05). In contrast, H-Ras expression was increased in the tumor. The expression of them was a close association with the differentiation and tumor-node-metastasis (TNM) stage of the tumor (p < .001; p = .035, respectively) and Rce1 was an independent prognostic indicator (95%Cl: 0.193–0.821; p = .013). Through targeted regulation of Rce1 by cDNA or small interfering RNA, results show that the lower expression of Rce1 facilitated EMT and promoted the invasion and metastasis of HCC (p < .05). Furthermore, the CO-IP experiment unfolded that Rce1 could bond with farnesyltransferase-β (FNTB) which mediated the expression of H-Ras. Conclusions: Rce1 inhibits EMT via target regulation H-Ras and suppress the early invasion and metastasis of HCC. It may be a potential therapeutic target and prognostic indicator for HCC. 相似文献

SEPT4 belongs to the Septin family with multiple functions in cell division, cytoskeletal organization and other processes.
This study aims to investigate the relationship between SEPT4_i1 isoform and human hepatocellular carcinoma (HCC). We showed
that over-expression of SEPT4_i1 in HCC cells was able to sensitize cells to serum starvation-induced apoptosis. By contrast,
knockdown of SEPT4_i1 expression in HCC cells was able to rescue cells from apoptosis induced by serum deprivation and to
promote cell growth. Expressional analysis of SEPT4_i1 in tumor tissues further revealed that SEPT4_i1 was significantly down-regulated
in human HCC tissues. Taken together, these data suggests a tumor suppressor role of SEPT4_i1 in HCC through regulating HCC
cell apoptosis. 相似文献
