Abstract
Ubiquitin E3 Ligase MARCH7 is involved in T cell proliferation and neuronal development. In our previous study, we demonstrated MARCH7 promoted malignant behavior of ovarian cancer via the nuclear factor (NF)-κB and Wnt/β-catenin signaling pathway. However, the expression and function of MARCH7 in cervical cancer remains unknown. The present study aimed to unravel the expression and function of MARCH7 in cervical cancer to elucidate its potential role in the diagnosis and pathogenesis of cervical cancer. Results indicated that the expression of MARCH7 was abnormally high in cervical cancer tissues than normal cervical tissues. However, silencing the expression of MARCH7 in HeLa cells resulted in decreased cell proliferation and invasion. Mechanistic investigations revealed that MARCH7 interacted with VAV2. Silencing the expression of MARCH7 in HeLa cells inhibited the VAV2-RAC1-CDC42 signaling pathway. Overall, the results of the present study identified MARCH7 as a candidate oncogene in cervical cancer, and a potential target for cervical cancer therapy.

Abstract
The objectives of the study were to investigate the functional role and potential mechanism of wild-type p53-induced phosphatase (Wip1) in cervical cancer cell line HeLa cells, along with the effect of knockdown of Wip1 in combination with γ-irradiation on the HeLa cells. Expression of Wip1 was silenced or overexpressed. After transfection, cell viability was determined. Moreover, γ-irradiation and SB203580 were performed to explore the effect of colony formation and cell apoptosis. Likewise, protein expression levels of p38, p-p38, p53, and p-p53 were assessed in the presence or not of SB203580 and overexpression of Wip1. Both the mRNA and protein levels of Wip1 were significantly decreased by transfection with Wip1-specific small interfering RNA (siRNA) but were significantly increased by transfection with pcDNA3.1-Wip1. Knockdown of Wip1 significantly decreased cell growth and colony formation ability and increased apoptotic rate. Additionally, better results were obtained by knockdown of Wip1 in combination with γ-irradiation. The protein expression levels of p-p38 (p < 0.05), p53 (p < 0.01), and p-p53 (p < 0.05) were all significantly increased by knockdown of Wip1. However, application of SB203580 reversed the effects. Our study confirms the important roles of Wip1 in cervical cancer. Knockdown of Wip1 enhances sensitivity to radiation in HeLa cells by inhibiting cell proliferation and inducing apoptosis through activation of p38 MAPK.

Abstract
Our previous study implied a correlation between inhibitors of differentiation-1 (Id-1) and cervical cancer development. However, how Id-1 contributes to cervical carcinogenesis is unknown. In the present study, we used an in vitro transformation model to investigate the role of Id-1 in the transformation of cervical cells. Human papillomavirus (HPV)-immortalized cervical epithelial cells (H8) were successfully transformed by exposure to the carcinogen N-nitrosopyrrolidine (NPYR). The expression of both Id-1 RNA and protein was significantly increased in transformed H8 cells, suggesting a possible role of Id-1 in cervical cell transformation. Ectopic expression of Id-1 in H8 cells potentiated NPYR-induced cell transformation. In contrast, silencing of Id-1 suppressed NPYR-induced H8 cell transformation. In addition, the expression of HPV E6 and E7 oncoproteins was upregulated while that of the tumor suppressors p53 and pRb was suppressed after H8 cell transformation. Our results suggest that Id-1 plays an oncogenic role in HPV-related cervical carcinogenesis, which sheds light on cervical cancer development mechanisms and implies that Id-1 is a potential target for cervical cancer prevention and therapy.

Abstract
PURPOSE Metastasis-associated in colon cancer 1 (MACC1) has been shown to play a critical role in several types of cancer. The purposes of this study were to evaluate MACC1 expression in cervical cancer and determine role of MACC1 small interference RNA (siRNA) in the growth and progression of cervical cancer. METHODS Immunohistochemical analysis of MACC1 expression was performed in different cervical lesion tissues. siRNA knockdown of MACC1 was performed. Cytoskeletal staining, RT-PCR, Western blot technology, transwell migration, MTT, and flow cytometry were used for identification of the functional roles of MACC1 siRNA in HeLa cells. RESULTS Immunohistochemistry demonstrated that MACC1 overexpression was detected in cervical cancer tissues. MACC1 siRNA transfection remarkably affected HeLa cell biological behaviors. Expression of MACC1 in HeLa cells was significantly down-regulated by MACC1 siRNA. In addition, knockdown of MACC1 in HeLa cells caused a significant decrease in cell proliferation or migration, and increased cell apoptosis rate. Flow cytometry showed that MACC1 siRNA may inhibit cell proliferation by interfering with cell mitosis and cell cycle progression. CONCLUSIONS These results suggest that MACC1 is a novel biomarker for cervical cancer diagnosis and a target for therapeutic interventions. Decreasing MACC1 expression by siRNA may prove to be an effective genetic therapy strategy.

Overexpression of cystic fibrosis transmembrane conductance regulator (CFTR) is associated with human cervical cancer malignancy, progression and prognosis. Gynecol Oncol 2012; 125:470-6. [PMID: 22366595 DOI: 10.1016/j.ygyno.2012.02.015] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2011] [Revised: 02/11/2012] [Accepted: 02/13/2012] [Indexed: 01/12/2023]
Abstract
OBJECTIVE To investigate the correlation of cystic fibrosis transmembrane conductance regulator (CFTR) to cervical cancer progression and prognosis by examining CFTR expression levels in different cervical tissues and cell lines. METHODS Paraffin-embedded cervical tissue samples (n=192) were collected for immunohistochemistry (IHC), while fresh cervical tissue samples (n=165) and human cervical cell lines were collected for protein and mRNA detection by quantitative real-time PCR and western blot, respectively. Correlations between CFTR expression levels to cancer clinicopathologic features and prognosis were statistically analyzed. RESULTS Both CFTR mRNA and protein expression gradually increased from normal to precancerous (LSIL, HSIL) and cervical cancer tissues (p<0.05). Furthermore, CFTR expression level was well-correlated to tumor stage (p<0.001), histological grades (p<0.001), lymphatic metastasis (p<0.001), vascular invasion (p<0.05), interstitial invasive depth (p<0.05), tumor size (p<0.05) and HPV infection (p<0.05). In vitro, CFTR mRNA and protein were expressed strongly both in SiHa and HeLa, but little was seen in Caski and H8 (p<0.05). More importantly, overexpression of CFTR conferred significantly poorer survival in cervical carcinoma (Log rank p=0.028), although it was not an independent predictor for prognosis according to multivariate analysis (p>0.05). CONCLUSIONS These results suggest that higher CFTR expression is closely associated with cervical cancer progression, aggressive behaviors and poorer prognosis, indicating that CFTR may function as a novel tumor marker, a prospective prognostic indicator and a potential therapeutic target for cervical cancer.

Abstract
It has been reported that metastasis-associated gene 1 (Mta1) is overexpressed in many malignant tumors with high metastatic potential. In addition, some studies indicated that MTA1 participated in invasion, metastasis, and survival of cancer cells by regulating cell migration, adhesion and proliferation. But the role of MTA1 is unclear in vitro in the development of cervical cancer cells. This study investigated whether and how MTA1 mediated cell proliferation, migration, invasion and adhesion in cervical cancer. MTA1 expression level was detected by Western blot in two cervical cancer cell lines of different invasion potentials. The effects of MTA1 expression on SiHa cell apoptosis, cycle, proliferation, migration, invasion and adhesion were tested by flow cytometry, MTT, wound-healing assay, Transwell assay and adhesion assay, respectively. The expression levels of p53, E-cadherin, and β-catenin activity were evaluated in untreated and treated cells. The results showed that MTA1 protein expression was significantly higher in SiHa than in HeLa, which was correlated well with the potential of migration and invasion in both cell lines. Furthermore, the cell invasion, migration and adhesion capabilities were decreased after inhibition of MTA1 expression mediated by Mta1-siRNA transfection in SiHa. However, no significant differences were found in cell apoptosis, cycle, and proliferation. In addition, E-cadherin and p53 protein levels were significantly up-regulated, while β-catenin was significantly down-regulated in SiHa transfected with the siRNA. These results demonstrated that MTA1 played an important role in the migration and invasion of cervical cancer cells. It was speculated that the decreased migration and invasion capability by inhibiting the MTA1 expression in the SiHa cell line may be mediated through the altered expression of p53, and E-cadherin/β-catenin complex. MTA1 could serve as a potential therapeutic target in cervical cancer.
