Abstract
BACKGROUND Classification of oral lichen planus (OLP) as a condition with malignant potential is still controversial. One of the major properties of malignancy is invasion. Ln332-γ2 chain plays a critical role in invasive activity of cancer cells. This study aims to compare Ln332-γ2 chain expression in OLP, oral epithelial dysplasia (OED) and oral squamous cell carcinoma (OSCC). METHODS Ln332-γ2 expression was evaluated in 16 epithelial hyperplasia with no dysplasia (group A), 16 OLP (group B), 18 OED (group C) and 18 OSCC (group D) by immunohistochemistry. RESULTS Except in A group, Ln332-γ2 expression was detected in other groups. There was a significant difference in Ln332-γ2 expression among B, C and D groups as well as between B and D, C and D groups (P< 0.001). However, there was no significant difference between B and C groups (P= 0.999). CONCLUSIONS According to the findings of this study, the likelihood of similarity of OLP with premalignant dysplastic lesion can be suggested. This is not corroborating OLP definitive transformation to an OSCC. But it might be advisable that OLPs with >10% Ln332- γ2 expression may have a higher risk of cellular invasion occurrence and malignant transformation.

Abstract
Extramammary Paget's disease (EMPD) is a rare malignant skin neoplasm characterized by intraepidermal proliferation of tumor cells. The tumor cells of EMPD may sometimes invade into the dermis or metastasize into the regional lymph nodes. Several studies have proposed mechanisms underlying the increased invasiveness of EMPD; however, molecular markers indicating invasiveness have yet to be well characterized. Laminin-5 (Lam-5), a heterotrimer composed of three chains (α3, β3, and γ2), is a major component of the basement membrane in many tissues. One of the chains, Lam-5 γ2, is a marker of invasion, because it often develops as a monomer in malignant neoplasms. We investigated the expression of Lam-5 γ2 and its role for the invasiveness in EMPD. Paraffin-embedded specimens of EMPD obtained from 36 patients were examined immunohistochemically for Lam-5 γ2. The cases adopted into this study comprised 16 cases of intraepidermal lesions and 20 cases with dermal invasion. The basement membrane seen in normal skin disappeared in one-third of non-invasive cases and in most invasive cases. The disappearance of Lam-5 γ2 in the basement membrane and its cytoplasmic expression was more observed in the invasive cases than non-invasive cases. Expression of Lam-5 γ2 may be a biological marker to predict invasiveness of EMPD.

Abstract
Cutaneous squamous cell carcinoma (cSCC) is the most common metastatic skin cancer, with increasing incidence worldwide. The molecular basis of cSCC progression to invasive and metastatic disease is still incompletely understood. Here, we show that fibroblasts and transforming growth factor-β (TGF-β) signaling promote laminin-332 synthesis in cancer cells in an activated H-Ras-dependent manner, which in turn promotes cancer cell invasion. Immunohistochemical analysis of sporadic UV-induced invasive human cSCCs (n = 208) revealed prominent cSCC cell specific immunostaining for laminin-332 γ2 chain, located in the majority of cases (90%, n = 173) in the invasive edge of the tumors. To mimic the progression of cSCC we established 3D spheroid cocultures using primary skin fibroblasts and HaCaT/ras-HaCaT human keratinocytes. Our results indicate that in 3D spheroids, unlike in monolayer cultures, TGF-β upregulates laminin-332 production, but only in cells that harbour oncogenic H-Ras. Accumulation of laminin-332 was prevented by both H-Ras knock down and inhibition of TGF-β signaling by SB431542 or RAdKD-ALK5 kinase-defective adenovirus. Furthermore, fibroblasts accelerated the invasion of ras-HaCaT cells through collagen I gels in a Ras/TGF-β signaling dependent manner. In conclusion, we demonstrate the presence of laminin-332 in the invasive front of cSCC tumors and report a new Ras/TGF-β-dependent mechanism that promotes laminin-332 accumulation and cancer cell invasion.

Tissue-Specific Gene Expression during Productive Human Papillomavirus 16 Infection of Cervical, Foreskin, and Tonsil Epithelium. J Virol 2019; 93:JVI.00915-19. [PMID: 31189705 DOI: 10.1128/jvi.00915-19] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Accepted: 06/03/2019] [Indexed: 02/06/2023] Open
Abstract
Epidemiological data confirm a much higher incidence of high-risk human papillomavirus 16 (HPV16)-mediated carcinogenesis of the cervical epithelium than for other target sites. In order to elucidate tissue-specific responses to virus infection, we compared gene expression changes induced by productive HPV16 infection of cervical, foreskin, and tonsil organotypic rafts. These rafts closely mimic persistent HPV16 infection, long before carcinogenesis sets in. The total number of gene expression changes varied considerably across the tissue types, with only 32 genes being regulated in common. Among them, we confirmed the Kelch-like family protein KLHL35 and the laminin-5 complex to be upregulated and downregulated, respectively, in all the three tissues. HPV16 infection induces upregulation of genes involved in cell cycle control, cell division, mitosis, DNA replication, and DNA damage repair in all the three tissues, indicative of a hyperproliferative environment. In the cervical and tonsil epithelium, we observe significant downregulation of genes involved in epidermis development, keratinocyte differentiation, and extracellular matrix organization. On the other hand, in HPV16-positive foreskin (HPV16 foreskin) tissue, several genes involved in interferon-mediated innate immunity, cytokine signaling, and cellular defenses were downregulated. Furthermore, pathway analysis and experimental validations identified important cellular pathways like STAT1 and transforming growth factor β (TGF-β) to be differentially regulated among the three tissue types. The differential modulation of important cellular pathways like TGF-β1 and STAT1 can explain the sensitivity of tissues to HPV cancer progression.IMPORTANCE Although the high-risk human papillomavirus 16 infects anogenital and oropharyngeal sites, the cervical epithelium has a unique vulnerability to progression of cancer. Host responses during persistent infection and preneoplastic stages can shape the outcome of cancer progression in a tissue-dependent manner. Our study for the first time reports differential regulation of critical cellular functions and signaling pathways during productive HPV16 infection of cervical, foreskin, and tonsil tissues. While the virus induces hyperproliferation in infected cells, it downregulates epithelial differentiation, epidermal development, and innate immune responses, according to the tissue type. Modulation of these biological functions can determine virus fitness and pathogenesis and illuminate key cellular mechanisms that the virus employs to establish persistence and finally initiate disease progression.

Abstract
Objectives Oral squamous cell carcinoma is associated with alterations in basement membrane. Laminin-332 is present in basal lamina and performs multiple biologic effects by γ2 chain. Matrix metalloproteinase acts disrupting extracellular components and was related to poor prognosis in cancer. Here, molecular profile of laminin-332 γ2 chain and matrix metalloproteinase-9 was assessed in oral lesions. Material and Methods The expression of laminin-332 γ2 chain and matrix metalloproteinase-9 (MMP-9) was examined by immunohistochemistry in 10 patients with high risk of malignant transformation oral lesions and 26 cases of oral squamous cell carcinoma (OSCC). Associations between microscopic and clinicopathologic features were established. Results Immunostaining of laminin-332 γ2 chain in high risk oral lesions was most detected in basement membrane which is continuous, while the majority of OSCC cases showed a discontinuous membrane (P = 0.001). It was observed a positive reaction for γ2 chain in invasive fronts and a higher expression in epithelial compartment of smoking patients with OSCC (P < 0.0001). In epithelium, MMP-9 expression was presented in all layers with no difference between lesions. However, an elevated immunostaining in stromal cells was associated with male patients (P = 0.0054), older than 60 years (P = 0.0101) and with OSCC. Conclusions Present study results support the hypothesis of changes in molecules expression in high risk oral lesions and oral squamous cell carcinoma. A relation between clinical and molecule profile was observed. Those molecules may represent a useful tool to predict oral cancer behaviour.

Abstract
OBJECTIVE The invasiveness of papillary thyroid carcinoma (PTC), including the occurrence of cervical lymph node metastasis, is the main determining factors contributing to recurrence and poor prognosis. Laminin 332 is a glycoprotein involved in cell migration and cancer cell invasion into surrounding tissues and is therefore related to poor prognosis in many cancers. Here, we investigated the expression and role of laminin 332 in PTC and examine the possibility that laminin 332 could be involved in the invasiveness of PTC. METHODS Laminin 332 expression was determined by immunohistochemical staining in all 40 patients. The correlations between laminin 332 expression and clinical factors were investigated. We examined the expression of the laminin 332 γ2 chain using reverse transcription polymerase chain reaction and western blotting in PTC cells and determined the relationship between the expression of laminin 332 and the invasiveness of these cell lines using cell invasion assays. RESULTS Laminin 332 was expressed specifically within tumor tissue. The frequency of laminin 332 γ2 chain expression was significantly correlated with cervical lymph node metastasis (p=0.003). Invasiveness increased as the expression of laminin 332 γ2 increased in the tested PTC cell lines. CONCLUSION Laminin 332 expression may be a useful marker for predicting lymph node metastasis in papillary thyroid carcinoma, and could increase the ability of cancer cells to invade, which would influence the prognosis of patients with PTC.

Abstract
Objective: Carcinoma of the uterine cervix is either the first or second most common malignancy in Indian women,
depending on the registry. Tumor growth and metastasis primarily are determined by angiogenesis and parameters
of the molecular environment including extracellular matrix elements, growth factors and cytokines. Effects of
chemo-irradiation on biomarkers like vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2) and laminin
in patients with carcinoma cervix therefore need to be explored. Methods: Circulatory and mRNA levels of VEGF,
Ang-2 and laminin in patients with stage III carcinoma cervix (n=40) were compared with those of normal healthy
women (n=20). Measurement was prior to treatment, and after chemotherapy and teleradiation, using high sensitivity
ELISA kits and Q-PCR. Clinical response was evaluated as per WHO criteria and was assessed for correlation with the
biochemical markers. Results: Levels of all the studied molecules were significantly (p<0.001) higher in patients than in
controls. After treatment significant decline (p<0.001) was noted. Out of 40 patients, 33 were complete responders and
7 were non-responders on clinical assessment. On comparison of before and after treatment levels of these molecules
complete responders showed significant decline whereas non-responders showed non-significant decrease. Follow-up
of the responders for 3 years, revealed 28 of 33 patients to still be disease free, the other 5 demonstrating recurrence.
Conclusions: Higher levels of angiogenic factors along with laminin indicate roles played in disease progression aiding
angiogenesis. These markers may serve as useful tools in post treatment disease mapping, for which available imaging
methods may not provide a true picture.

Abstract
A new method for the selective determination of laminin-5 concentration using a biosensor and surface plasmon resonance imaging (SPRI) technique is presented. A biosensor based on the specific interaction of laminin-5 with rabbit polyclonal antibody was constructed. The analytically useful dynamic response range of the biosensor is between 0.014 and 0.1 ng mL(-1). The detection limit is 4 pg mL(-1). The potential influence of interferences on the SPRI signal was investigated, and the high selectivity of the biosensor was confirmed. In order to demonstrate the potential application of the biosensor, laminin-5 concentration in blood plasma was determined. The results were compared with the laminin-5 concentration obtained by the commercial enzyme-linked immunosorbent assay (ELISA) kit. A comparison of results from healthy donors obtained by SPRI measurement and ELISA indicates that they are close and shows good agreement with the data reported in the literature. The plasma samples of bladder cancer patients gave higher concentration measured with specific biosensor than by ELISA assay. The study shows the clear difference in concentration of laminin-5 in healthy humans and patients with bladder cancer. Extensive clinical studies using the newly developed method can result in an increase in the use of laminin-5 as a potential cancer marker.

Abstract
OBJECTIVE To explore the expression of lamininγ2 in extrahepatic cholangiocarcinoma (EHCC) tissues and its influence on tumor invasion and metastasis. MATERIALS AND METHODS Paraffin embedding samples of cancer, para-cancer, lymph node metastatic and hepatic metastatic tissues from 79 patients undergoing EHCC resection were collected. Expression of lamininγ2 was detected by immunohistochemistry and its relationship with clinical pathological characteristics and the prognosis of EHCC patients were analyzed. RESULTS Lamininγ2 showed negative staining in para-cancer tissues, but demonstrated a 51.9% (41/79) positive expression rate in extracellular matrix (ECM) or cytoplasm of EHCC tissues. In lymph node metastatic and distant metastatic nidi, expression of lamininγ2 was significantly higher than in the primary nidi (χ2=7.4173, P=0.0065; χ2=4.0077, P=0.0453). The expression was in obvious association with lymph node metastasis (P<0.01), but had no relevance with age, gender, tumor location, tumor stage, differentiation and distant metastasis in ECM (P>0.05), whereas it was in marked connection with lymph node and distant metastasis (P<0.05 or P<0.01), but had no relationship with age, gender, tumor location, tumor stage and differentiation in cytoplasm (P>0.05). However, the median survival time and median recurrent period of patients with positive expression of lamininγ2 in both cytoplasm and ECM of tumor cells, only in ECM and only in cytoplasm, were evidently lower than with negative expression of lamininγ2 in RCM and cytoplasm (P<0.05 or P<0.01). Further Cox regression analysis showed that the positive expression of lamininγ2 and the tumor differentiation were independent risk factors influencing the prognosis of EHCC patients. CONCLUSIONS Abnormal expression of lamininγ2 may be closely associated with invasion and metastasis of tumor cells, and thus a potential molecular marker for prognosis of EHCC patients.

Abstract
Background Comparison of tissue microarray results of 29 cervical cancer and 27 normal cervix tissue samples using immunohistochemistry revealed considerable reorganization of the fibrillar stroma of these tumors. Preliminary densitometry analysis of laminin-1, α-smooth muscle actin (SMA) and fibronectin immunostaining demonstrated 3.8-fold upregulation of laminin-1 and 5.2-fold increase of SMA in the interstitial stroma, indicating that these proteins and the activated fibroblasts play important role in the pathogenesis of cervical cancer. In the present work we investigated the role of normal and tumor-associated fibroblasts. Methods In vitro models were used to throw light on the multifactorial process of tumor-stroma interaction, by means of studying the cooperation between tumor cells and fibroblasts. Fibroblasts from normal cervix and cervical cancers were grown either separately or in co-culture with CSCC7 cervical cancer cell line. Changes manifest in secreted glycoproteins, integrins and matrix metallo-proteases (MMPs) were explored. Results While normal fibroblasts produced components of interstitial matrix and TGF-β1 that promoted cell proliferation, cancer-associated fibroblasts (CAFs) synthesized ample amounts of laminin-1. The following results support the significance of laminin-1 in the invasion of CSCC7 cells: 1.) Tumor-associated fibroblasts produced more laminin-1 and less components of fibrillar ECM than normal cells; 2.) The production of laminin chains was further increased when CSCC7 cells were grown in co-culture with fibroblasts; 3.) CSCC7 cells were capable of increasing their laminin production; 4.) Tumor cells predominantly expressed integrin α6β4 laminin receptors and migrated towards laminin. The integrin profile of both normal and tumor-associated fibroblasts was similar, expressing receptors for fibronectin, vitronectin and osteopontin. MMP-7 secreted by CSCC7 cells was upregulated by the presence of normal fibroblasts, whereas MMP-2 produced mainly by fibroblasts was activated in the presence of CSCC7 cells. Conclusions Our results indicate that in addition to degradation of the basement membrane, invasion of cervical cancer is accomplished by the remodeling of the interstitial stroma, which process includes decrease and partial replacement of fibronectin and collagens by a laminin-rich matrix.

Abstract
MicroRNAs (miRNAs) are a class of small non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. As a highly conserved miRNA across a variety of species, microRNA-218 (miR-218) was found to play pivotal roles in tumorigenesis and progression. A group of evidence has demonstrated that miR-218 acts as a tumor suppressor by targeting many oncogenes related to proliferation, apoptosis and invasion. In this review, we provide a complex overview of miR-218, including its regulatory mechanisms, known functions in cancer and future challenges as a potential therapeutic target in human cancers.

Abstract
The Caco-2 cell line is one of the most important in vitro models for enterocytes, and is used to study drug absorption and disease, including inflammatory bowel disease and cancer. In order to use the model optimally, it is necessary to map its functional entities. In this study, we have generated genome-wide maps of active transcription start sites (TSSs), and active enhancers in Caco-2 cells with or without tumour necrosis factor (TNF)-α stimulation to mimic an inflammatory state. We found 520 promoters that significantly changed their usage level upon TNF-α stimulation; of these, 52% are not annotated. A subset of these has the potential to confer change in protein function due to protein domain exclusion. Moreover, we locate 890 transcribed enhancer candidates, where ∼50% are changing in usage after TNF-α stimulation. These enhancers share motif enrichments with similarly responding gene promoters. As a case example, we characterize an enhancer regulating the laminin-5 γ2-chain (LAMC2) gene by nuclear factor (NF)-κB binding. This report is the first to present comprehensive TSS and enhancer maps over Caco-2 cells, and highlights many novel inflammation-specific promoters and enhancers.

Abstract
Objective This study is to investigate the role of miR-143 expression in cervical squamous cell carcinoma (SCC). Methods The expression level of miR-143 was examined by quantitative real-time PCR. Human papillomavirus (HPV) genotype was detected by HPV genotype detection kit. The expression level of bcl-2 was detected by immunohistochemistry. Results The positive rate of HPV was 78% in the patients of cervical SCC. The most prevalent genotype was HPV16, with a positive rate of 42%. The expression level of miR-143 was significantly lower in the cervical SCC tissues than that in the normal cervical tissues (Z = −2.180, P = 0.029). Down-regulated miR-143 expression was associated with tumor size, lymph node metastasis and HPV16 infection in cervical cancer patients. No significant associations were found between the expression levels of miR-143 and age, clinical stage, differentiation or lymph vascular space invasion. And, in cervical SCC patients after treatment with Taxol chemotherapy, the expression level of miR-143 was higher and the positive expression of bcl-2 protein was lower. However, the differences in expression changes of miR-143 and bcl-2 were not statistically significant (miR-143, Z = −0.763, P = 0.446; bcl-2 protein, χ2 = 2.277, P = 0.131). Conclusion Down-regulated miR-143 is related with tumor size, lymph node metastasis and HPV16 infection in cervical SCC, but miR-143 does not participate in the Taxol sensitivity response.

Abstract
Background As an acute-phase protein, serum amyloid A (SAA) is expressed primarily in the liver. However, its expression in extrahepatic tissues, especially in tumor tissues, was also demonstrated recently. In our study, we investigated the expression of SAA in uterine cervical carcinomas, and our results suggested its potential as a serum biomarker. Methods Quantitative real-time polymerase chain reaction (RT-PCR), immunohistochemistry (IHC) and enzyme-linked immunosorbent assay (ELISA) were used to evaluate the SAA gene and protein expression levels in the tissues and sera of patients with non-neoplastic lesions (NNLs), cervical intraepithelial neoplasia (CIN) and cervical carcinoma (CC). Results Compared with NNLs, the SAA gene (SAA1 and SAA4) expression levels were significantly higher in uterine CC (mean copy numbers: 138.7 vs. 5.01, P < 0.000; and 1.8 vs. 0.079, P = 0.001, respectively) by real-time PCR. IHC revealed cytoplasmic SAA protein staining in tissues from adenocarcinoma and squamous cell carcinoma of the cervix. The median serum concentrations (μg/ml) of SAA were 6.02 in patients with NNLs and 10.98 in patients with CIN (P = 0.31). In contrast, the median serum SAA concentration was 23.7 μg/ml in uterine CC patients, which was significantly higher than the SAA concentrations of the NNL group (P = 0.002) and the CIN group (P = 0.024). Conclusions Our data suggested that SAA might be a uterine CC cell product. High SAA concentrations in the serum of CC patients may have a role in monitoring disease occurrence and could have therapeutic applications.

Abstract
Cancer genomics unveils many cancer-related mutations, including some chromosome 20 (Chr.20) genes. The mutated messages have been found in the corresponding mRNAs; however, whether they could be translated to proteins still requires more evidence. Herein, we proposed a transomics strategy to profile the expression status of human Chr.20 genes (555 in Ensembl v72). The data of transcriptome and translatome (the mRNAs bound with ribosome, translating mRNAs) revealed that ∼80% of the coding genes on Chr.20 were detected with mRNA signals in three liver cancer cell lines, whereas of the proteome identified, only ∼45% of the Chr.20 coding genes were detected. The high amount of overlapping of identified genes in mRNA and RNC-mRNA (ribosome nascent-chain complex-bound mRNAs, translating mRNAs) and the consistent distribution of the abundance averages of mRNA and RNC-mRNA along the Chr.20 subregions in three liver cancer cell lines indicate that the mRNA information is efficiently transmitted from transcriptional to translational stage, qualitatively and quantitatively. Of the 457 genes identified in mRNAs and RNC-mRNA, 136 were found to contain SNVs with 213 sites, and >40% of these SNVs existed only in metastatic cell lines, suggesting them as the metastasis-related SNVs. Proteomics analysis showed that 16 genes with 20 SNV sites were detected with reliable MS/MS signals, and some SNVs were further validated by the MRM approach. With the integration of the omics data at the three expression phases, therefore, we are able to achieve the overall view of the gene expression of Chr.20, which is constructive in understanding the potential trend of encoding genes in a cell line and exploration of a new type of markers related to cancers.

Loss of TAK1 increases cell traction force in a ROS-dependent manner to drive epithelial-mesenchymal transition of cancer cells. Cell Death Dis 2013; 4:e848.

Abstract
Epithelial–mesenchymal transition (EMT) is a crucial step in tumor progression, and the TGFβ–SMAD signaling pathway as an inductor of EMT in many tumor types is well recognized. However, the role of non-canonical TGFβ–TAK1 signaling in EMT remains unclear. Herein, we show that TAK1 deficiency drives metastatic skin squamous cell carcinoma earlier into EMT that is conditional on the elevated cellular ROS level. The expression of TAK1 is consistently reduced in invasive squamous cell carcinoma biopsies. Tumors derived from TAK1-deficient cells also exhibited pronounced invasive morphology. TAK1-deficient cancer cells adopt a more mesenchymal morphology characterized by higher number of focal adhesions, increase surface expression of integrin α5β1 and active Rac1. Notably, these mutant cells exert an increased cell traction force, an early cellular response during TGFβ1-induced EMT. The mRNA level of ZEB1 and SNAIL, transcription factors associated with mesenchymal phenotype is also upregulated in TAK1-deficient cancer cells compared with control cancer cells. We further show that TAK1 modulates Rac1 and RhoA GTPases activities via a redox-dependent downregulation of RhoA by Rac1, which involves the oxidative modification of low-molecular weight protein tyrosine phosphatase. Importantly, the treatment of TAK1-deficient cancer cells with Y27632, a selective inhibitor of Rho-associated protein kinase and antioxidant N-acetylcysteine augment and hinders EMT, respectively. Our findings suggest that a dysregulated balance in the activation of TGFβ–TAK1 and TGFβ–SMAD pathways is pivotal for TGFβ1-induced EMT. Thus, TAK1 deficiency in metastatic cancer cells increases integrin:Rac-induced ROS, which negatively regulated Rho by LMW-PTP to accelerate EMT.

Abstract
Background Kombucha, a fermented tea (KT) is claimed to possess many beneficial properties. The aim of this study was to evaluate clinical and histopathological alterations of Kombucha tea and Nitrofurazone on cutaneous full-thickness wounds healing in rat. Methods In present study 24 Wister -albino rats weighing 150–200 g were selected and divided to two treatment groups as Nitrofurazone ointment (0.2%) and Kombucha tea. Subsequently, the anesthesia was exerted by Ketamin hydrochloride 10% (40 mg/kg) and Xylasine (2 mg/kg) through intra muscular (IM) route. Furthermore, upon preparation of dorsal region of the animal for surgery, a piece of full-thickness skin removed (2 × 2 cm). In order to comparing wounds healing clinically and histologically, once every four days from the commencement, the wounds were photographed and the healed surface was measured by Scion image software. Result The clinical findings indicated that the Kombucha fungus resulted in precipitating healing than Nitrofurazone; however, it was not significant (p > 0.05). In order to pathological comparing of wound healing process, several wound biopsies were taken on 4, 8, 12, 16 and 20th days. Additionally, the histopathological results demonstrated that there was inflammation in Nitrofurazone group through twelveth day, somehow the epithelium was formed and abundant vessels were visible. Although on 16th day and the previous days the healing condition of Kombucha fungus was considered as minimal rate, revealing it is similar to Nitrofurazone group on 20th day. Conclusions To wrap up. These observations suggest that the Kombucha fungus healing quality was rapid from 12th day to the end of the research, whereas no significant difference was observed.

Abstract
Objective Accumulating evidence for differential expression of microRNA-224 (miR-224) in various types of human cancer suggests that it may be play a crucial role in tumor biology. The previous microarray detection also shown that miR-224 was one of miRNAs with significant upregulation in cervical cancer tissues relative to adjacent normal tissues. However, little is known about the function of miR-224 in human cervical cancer. The aim of this study was to investigate the clinical significance of miR-224 expression in cervical cancer. Methods MiR-224 expression in 126 pairs of fresh human cervical cancer and adjacent normal tissues was measured by real-time quantitative RT-PCR assay. Results miR-224 expression was significantly upregulated in cervical cancer tissues when compared with corresponding adjacent normal tissues (P < 0.001). It was also significantly higher in the cancerous tissues of patients with advanced FIGO stage cervical cancer than those with early FIGO stage (P = 0.02). In addition, miR-224 was expressed at significantly higher levels in lymph node metastasis-positive patients than in lymph node metastasis-negative patients (P = 0.008). Moreover, we found that lesser differentiated tumors expressed higher miR-224 (P = 0.03). Finally, there were sufficient evidence to confirm its value in the status of vascular invasion (P = 0.01) and human papillomavirus (HPV) infection (P = 0.02) in cervical cancer. More importantly, Kaplan-Meier analysis showed that cervical cancer patients with high miR-224 expression tend to have shorter overall survival. In multivariate analysis stratified for known prognostic variables, miR-224 was identified as an independent prognostic marker. Conclusion Our data indicated that miR-224 upregulation was associated with aggressive progression and poor prognosis in cervical cancer. MiR-224 was identified for the first time as an independent marker for predicting the clinical outcome of cervical cancer patients.
