Abstract
Background High mortality rates are prevalent among patients with non-small-cell lung cancer (NSCLC), and effective therapeutic targets are key prognostic factors. Fascin actin-bundling protein 1 (FSCN1) promotes NSCLC; however, its role as an RNA-binding protein in NSCLC remains unexplored. Therefore, we aimed to explore FSCN1 expression and function in A549 cells. Method We screened for alternative-splicing events and differentially expressed genes (DEGs) after FSCN1 silence via RNA-sequencing (RNA-seq). FSCN1 immunoprecipitation followed by RNA-seq were used to identify target genes whose mRNA expression and pre-mRNA alternative-splicing levels might be influenced by FSCN1. Results Silencing FSCN1 in A549 cells affected malignant phenotypes; it inhibited proliferation, migration, and invasion, and promoted apoptosis. RNA-seq analysis revealed 2,851 DEGs and 3,057 alternatively spliced genes. Gene ontology-based functional enrichment analysis showed that downregulated DEGs and alternatively splicing genes were enriched for the cell-cycle. FSCN1 promoted the alternative splicing of cell-cycle-related mRNAs involved in tumorigenesis (i.e., BCCIP, DLGAP5, PRC1, RECQL5, WTAP, and SGO1). Combined analysis of FSCN1 RNA-binding targets and RNA-seq data suggested that FSCN1 might affect ACTG1, KRT7, and PDE3A expression by modulating the pre-mRNA alternative-splicing levels of NME4, NCOR2, and EEF1D, that were bound to long non-coding RNA transcripts (RNASNHG20, NEAT1, NSD2, and FTH1), which were highly abundant. Overall, extensive transcriptome analysis of gene alternative splicing and expression levels was performed in cells transfected with FSCN1 short-interfering RNA. Our data provide global insights into the regulatory mechanisms associated with the roles of FSCN1 and its target genes in lung cancer.

Abstract
BACKGROUND Ocular neovascularization is a leading cause of blindness and visual impairment. While intravitreal anti-VEGF agents can be effective, they do have several drawbacks, such as endophthalmitis and drug resistance. Additional studies are necessary to explore alternative therapeutic targets. METHODS Bioinformatics analysis and quantitative RT-PCR were used to detect and verify the FSCN1 expression levels in oxygen-induced retinopathy (OIR) and laser-induced choroidal neovascularization (CNV) mice model. Transwell, wound scratching, tube formation, three-dimensional bead sprouting assay, rhodamine-phalloidin staining, Isolectin B4 staining and immunofluorescent staining were conducted to detect the role of FSCN1 and its oral inhibitor NP-G2-044 in vivo and vitro. HPLC-MS/MS analysis, cell apoptosis assay, MTT assay, H&E and tunnel staining, visual electrophysiology testing, visual cliff test and light/dark transition test were conducted to assess the pharmacokinetic and security of NP-G2-044 in vivo and vitro. Co-Immunoprecipitation, qRT-PCR and western blot were conducted to reveal the mechanism of FSCN1 and NP-G2-044 mediated pathological ocular neovascularization. RESULTS We discovered that Fascin homologue 1 (FSCN1) is vital for angiogenesis both in vitro and in vivo, and that it is highly expressed in oxygen-induced retinopathy (OIR) and laser-induced choroidal neovascularization (CNV). We found that NP-G2-044, a small-molecule inhibitor of FSCN1 with oral activity, can impede the sprouting, migration, and filopodia formation of cultured endothelial cells. Oral NP-G2-044 can effectively and safely curb the development of OIR and CNV, and increase efficacy while overcoming anti-VEGF resistance in combination with intravitreal aflibercept (Eylea) injection. CONCLUSION Collectively, FSCN1 inhibition could serve as a promising therapeutic approach to block ocular neovascularization.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is a disease with increasing incidence worldwide that leads to deformity and death. In OSCC, fascin actin-bundling protein 1 (FSCN1) is an oncogene involved in the tumorigenesis process. However, the functions and potential mechanisms of FSCN1 in the OSCC tumorigenesis process have not been reported thus far. METHODS We used qRT‒PCR to detect the expression of FSCN1 in 40 paired OSCC tumor tissues (tumor) and neighboring noncancerous tissues. The role of FSCN1 was also assessed in vitro through colony formation, CCK-8, and transwell assays. Moreover, glucose consumption was detected. Western blotting was used to confirm the interaction of FSCN1, IRF4 and AKT. RESULTS FSCN1 was remarkably overexpressed in OSCC tissues and cell lines compared to corresponding controls. In addition, colony formation, CCK-8, and transwell assays revealed a notable reduction in OSCC growth and invasion when FSCN1 was silenced. FSCN1 silencing remarkably suppressed OSCC glycolysis. Mechanistic studies showed that FSCN1 achieves its function partially by activating interferon regulatory factor 4 (IRF4) and the AKT pathway in OSCC. CONCLUSION In conclusion, our study investigated the functions and mechanisms of the FSCN1/IRF4/AKT pathway in OSCC progression. In OSCC, FSCN1 is likely to be a biomarker and therapeutic target.

Abstract
Arsenic ranks at the top among all toxic metals and poses a serious threat to human health. Inorganic arsenite and arsenate compounds have been classified as human carcinogens in various types of cancers. Maternally expressed gene 3 (MEG3), a tumor suppressor that is commonly lost in cancer, was investigated in this study for its role in the migration and invasion of arsenic-transformed cells. Our results showed that MEG3 was downregulated in both arsenic-transformed cells (As-T) and cells treated with low doses of arsenic for three months (As-treated). The analysis using TCGA dataset revealed that MEG3 expression was significantly reduced in the tumor tissues from human lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) compared to normal lung tissues. The results from the methylation-specific PCR (MSP) assay demonstrated enhanced methylation in the MEG3 promoters in both As-T and As-treated cells, indicating that increased methylation of the MEG3 promoter caused MEG3 downregulation in these cells. Moreover, As-T cells displayed increased migration and invasion and higher levels of NAD(P)H quinone dehydrogenase 1 (NQO1) and fascin actin-bundling protein 1 (FSCN1). Consistently, the results from immunohistochemistry staining showed that both NQO1 and FSCN1 are highly expressed in human lung squamous cell carcinoma tissues compared to those in normal lungs. Knockdown of MEG3 in normal BEAS-2B cells also led to increased migration and invasion, along with elevated levels of NQO1 and FSCN1. The negative regulation of MEG3 on FSCN1 was restored by NQO1 overexpression in both As-T and BEAS-2B cells. The results from immunoprecipitation assays confirmed the direct binding of NQO1 to FSCN1. Overexpression of NQO1 increased migration and invasion abilities in BEAS-2B cells, while knockdown of NQO1 by its shRNA reduced these two hallmarks of cancer. Interestingly, the reduced migration and invasion by NQO1 knockdown were restored by FSCN1. Collectively, the loss of MEG3 upregulated NQO1, which in turn stabilized FSCN1 protein through its direct binding, resulting in elevated migration and invasion in arsenic-transformed cells.

Abstract
BACKGROUND Metastatic prostate cancer (mPCa) has a poor prognosis with limited treatment options. The high mobility of tumor cells is the key driving characteristic of metastasis. However, the mechanism is complex and far from clarified in PCa. Therefore, it is essential to explore the mechanism of metastasis and discover an intrinsic biomarker for mPCa. METHODS Transcriptome sequencing data and clinicopathologic features of PCa from multifarious public databases were used to identify novel metastatic genes in PCa. The PCa tissue cohort containing 102 formalin-fixed paraffin-embedded (FFPE) samples was used to evaluate the clinicopathologic features of synaptotagmin-like 2 (SYTL2) in PCa. The function of SYTL2 was investigated by migration and invasion assays and a 3D migration model in vitro and a popliteal lymph node metastasis model in vivo. We performed coimmunoprecipitation and protein stability assays to clarify the mechanism of SYTL2. RESULTS We discovered a pseudopodia regulator, SYTL2, which correlated with a higher Gleason score, worse prognosis and higher risk of metastasis. Functional experiments revealed that SYTL2 promoted migration, invasion and lymph node metastasis by increasing pseudopodia formation in vitro and in vivo. Furthermore, SYTL2 induced pseudopodia formation by enhancing the stability of fascin actin-bundling protein 1 (FSCN1) by binding and inhibiting the proteasome degradation pathway. Targeting FSCN1 enabled rescue and reversal of the oncogenic effect of SYTL2. CONCLUSIONS Overall, our study established an FSCN1-dependent mechanism by which SYTL2 regulates the mobility of PCa cells. We also found that the SYTL2-FSCN1-pseudopodia axis may serve as a pharmacological and novel target for treating mPCa.

Abstract
PURPOSE With the heterogeneous genetic background, prognosis prediction and therapeutic targets for testicular germ cell tumors (TGCTs) are still unclear. We defined the tumor immune microenvironment activation status (TIMEAS). METHODS We collected a total of 314 TGCT patients from four cohorts, including a 48-case microarray. A nonnegative matrix factorization algorithm was applied to identify the "immune factor", derived the top 150 weighted genes to divide patients into immune and non-immune classes, and further separated the immune class into activated and exhausted subgroups by nearest template prediction. Tumor mutant burden, gene mutation, and copy number alteration were compared with our recently developed package "MOVICS". A random forest algorithm was performed to establish a prediction model with fewer genes. Immunohistochemistry staining was performed to identify TIMEAS in the microarray. RESULTS We constructed the TIMEAS in the TCGA-TGCT cohort and further validated it in the GSE3218 and GSE99420 cohorts. The immune class contained the activated status of T-lymphocytes, B-lymphocytes, and macrophages, while Treg cells and the WNT/TGFβ signature were more activated in the immune-suppressed subgroup. Patients in the immune-exhausted subgroup had the worst prognosis, and 22.9% of patients in the immune-activated subgroup had KRAS mutations, which might stimulate the response of the immune system and lead to a favorable prognosis. The immune-exhausted group benefited more from chemotherapy, while the immune-activated subgroup responded well to anti-PD-1/PD-L1 therapy. FSCN1 was validated as the target of the immune-exhausted microenvironment by immunohistochemistry. CONCLUSION TIMEAS classification can separate TGCT patients; patients in the immune-activated subgroup could benefit more from anti-PD-L1 immunotherapy, and those in the immune-exhausted subgroup are more suitable for chemotherapy.

Abstract
FSCN1, an actin-bundling protein, is highly expressed in almost all metastatic tumors and is associated with the poor prognosis. In breast cancer FSCN1 is highly expressed in basal-like and triple negative subgroups. There is significant progress in understanding the role of fascin in breast cancer. Studies on FSCN1 in recent years have revealed that FSCN1 not only promotes tumor migration, invasion, metastic colonization, cancer cell self-renewal and drug resistance, but also regulates glucose and lipid metabolism and mitochondrial remodeling in tumor cells. In this review, we focus on the structure and regulatory mechanism of FSCN1 in breast tumorigenesis and metastasis, and discuss the clinical value of FSCN1 with the aim to provide a direction for further research in this field.

Abstract
BACKGROUND The study of molecular markers for diagnosis and prognosis is of great clinical significance for HNSCC patients. In this study, we proposed that FSCN1 has a potential indication for prognosis and is essential for the migration of HNSCC. METHODS We analyzed the expression and survival association of FSCN1 in HNSCC using TCGA data. We compared the expression of FSCN1 in tumors from primary and metastasis HNSCC patients using QPCR, western blotting, and immunochemistry staining. We determined the migration velocity of multiple HNSCC cell lines using a chemotaxis migration assay. We analyzed the correlation between FSCN1 expression and HNSCC cell migration. We also test the effect of FSCN1 knockdown and overexpression on HNSCC cell migration. RESULTS FSCN1 was overexpressed in HNSCC than pair normal tissues and metastasis HNSCC than primary HNSCC. FSCN1 expression was associated with significantly poorer overall survival of HNSCC patients. FSCN1 was potentially associated with immune cell infiltration and migration-associated genes. FSCN1 level was correlated with the migration in HNSCC cell lines. Knockdown of FSCN1 reduced the migration and the overexpression of FSCN1 promoted the migration of HNSCC cell lines. CONCLUSION FSCN1 is a potential prognostic marker and a critical biomolecule for the migration of HNSCC.

Abstract
Ovarian cancer seriously threatens the health of women. LncRNA CRNDE is known to be upregulated in ovarian cancer. However, the mechanism by which CRNDE regulates the progress of ovarian cancer is largely unknown. MTT assay was applied to measure the cell viability. Colony formation assay was used to measure the cell proliferation. Cell migration was tested by wound healing, and Transwell assay was performed to detect cell invasion. In addition, the expression of miR-423-5p, CRNDE and FSCN1 were detected by RT-qPCR and western blotting, respectively. Meanwhile, dual-luciferase reporter assay and RIP assay were performed to explore the correlation between miR-423-5p and CRNDE (or FSCN1). CRNDE and FSCN1 were upregulated in ovarian cancer cells (SKOV3, CAOV-3, IGROV1, A2780 and C13K), while miR-423-5p was downregulated. Moreover, silencing of FSCN1/CRNDE significantly decreased proliferation, migration and invasion of ovarian cancer cells (SKOV3 and CI3K) via suppressing MMP-2 and MMP-9. In addition, CRNDE could sponge miR-423-5p, and FSCN1 was confirmed to be the direct target of miR-423-5p. Furthermore, CRNDE knockdown-induced inhibition of FSCN1 was notably reversed by miR-423-5p downregulation. Knockdown of CRNDE inhibited cell proliferation, migration and invasion of ovarian cancer via miR-423-5p/FSCN1 axis. Thus, CRNDE may serve a new target for ovarian cancer.

Abstract
Fascin actin-bundling protein 1 (FSCN1), an actin-bundling protein associated with cell migration and invasion, is highly expressed in various tumor tissues. FSCN1 has also been reported to be a marker of increased invasive potential in cervical cancers. However, the functions of FSCN1 are still not fully understood in cervical cancers. Here, the gene expression profile of HeLa cells transfected with FSCN1 shRNA (shFSCN1) was compared with that of cells transfected with empty vector (shCtrl). The results showed that shFSCN1 extensively affected the transcription level of 5,043 genes in HeLa cells. In particular, Gene Ontology (GO) analysis showed that a large number of upregulated genes were annotated with terms including transcription regulation and DNA binding. The downregulated genes were enriched in some cancer pathways, including angiogenesis and cell adhesion. qPCR validation confirmed that FSCN1 knockdown significantly affected the expression of selected genes in HeLa cells either negatively or positively. Expression analysis in TCGA (The Cancer Genome Atlas) revealed that FSCN1 had negative correlations with several transcription factors and a positive correlation with an angiogenic factor (angiopoietin like 4, ANGPTL4) in cervical tumor tissue. In particular, validation by Western blotting showed that FSCN1 knockdown decreased the protein level of ANGPTL4. Our results demonstrated that FSCN1 is not only an actin-binding protein but also a transcriptional regulator and an angiogenic factor in cervical cancer. Thus, our study provides important insights for further study on the regulatory mechanism of FSCN1 in cervical cancer.

Abstract
BACKGROUND Pancreatic cancer is a lethal malignancy in both sexes throughout the world. Circular RNAs (circRNAs) have been implicated in the development of pancreatic cancer by operating as competing endogenous RNAs (ceRNAs). Here, we explored circ_0099999-mediated ceRNA activity in regulating pancreatic tumorigenesis. METHODS Ribonuclease R (RNase R) and subcellular localization assays were utilized to characterize circ_0099999. The levels of circ_0099999, microRNA (miR)-330-5p, and fascin actin-bundling protein 1 (FSCN1) were gauged by quantitative real-time PCR (qRT-PCR) and western blot. Cell proliferation, colony formation, apoptosis, migration, and invasion were evaluated by the Cell Counting Kit-8 (CCK-8), colony formation, flow cytometry, and transwell assays, respectively. The levels of glucose consumption and lactate production were determined using the assay kits. A direct relationship between miR-330-5p and circ_0099999 or FSCN1 was validated by dual-luciferase reporter assay. Tumour xenograft assays were used to analyse the role of circ_0099999 in vivo. RESULTS Circ_0099999 was highly up-regulated in pancreatic cancer tissues and cells. Knockdown of circ_0099999 impeded cell proliferation, migration, invasion, glycolysis, and promoted apoptosis in vitro, as well as diminished tumour growth in vivo. Circ_0099999 targeted miR-330-5p, and miR-330-5p was a downstream mediator of circ_0099999 function. FSCN1 was a direct and functional target of miR-330-5p. Furthermore, circ_0099999 operated as a ceRNA for miR-330-5p to modulate FSCN1 expression. CONCLUSIONS Our findings established a novel causal mechanism, circ_0099999/miR-330-5p/FSCN1 ceRNA crosstalk, in regulating pancreatic carcinogenesis and provided that inhibition of circ_0099999 might have therapeutic benefits in pancreatic cancer.

Abstract
Fascin actin-bundling protein 1 (FSCN1) is a highly conserved actin-bundling protein that cross links F-actin microfilaments into tight, parallel bundles. Elevated FSCN1 levels have been reported in many types of human cancers and have been correlated with aggressive clinical progression, poor prognosis, and survival outcomes. The overexpression of FSCN1 in cancer cells has been associated with tumor growth, migration, invasion, and metastasis. Currently, FSCN1 is recognized as a candidate biomarker for multiple cancer types and as a potential therapeutic target. The aim of this study was to provide a brief overview of the FSCN1 gene and protein structure and elucidate on its actin-bundling activity and physiological functions. The main focus was on the role of FSCN1 and its upregulatory mechanisms and significance in cancer cells. Up-to-date studies on FSCN1 as a novel biomarker and therapeutic target for human cancers are reviewed. It is shown that FSCN1 is an unusual biomarker and a potential therapeutic target for cancer.

Abstract
It has been reported that rs67085638 in long non-coding RNAs (lncRNA)-CCAT1 was associated with the risk of tumorigenesis. Also, CCAT1 could affect chemoresistance of cancer cells to paclitaxel (PTX) via regulating miR-24-3p and FSCN1 expression. In this study, we aimed to investigate the effect of rs67085638 on the expression of CCAT1/miR-24-3p/FSCN1 and the response of colon cancer to the treatment of PTX. 48 colon cancer patients were recruited and grouped by their genotypes of rs67085638 polymorphism as a CC group (N = 28) and a CT group (N = 20). PCR analysis, IHC assay and Western blot, TUNEL assay and flow cytometry were conducted. LncRNA-CCAT1 and FSCN1 mRNA/protein were overexpressed, whereas miR-24-3p was down-regulated in the CT-genotyped patients and cells compared with those in the CC-genotyped patients and cells. The survival of colon cancer cells was decreased, whereas the apoptosis of colon cancer cells was increased by PTX treatment in a dose-dependent manner. MiR-24-3p was validated to target lncRNA-CCAT1 and FSCN1 mRNA, and the overexpression of CCAT1 could reduce the expression of miR-24-3p although elevating the expression of FSCN1. Knockdown of lncRNA-CCAT1 partly reversed the suppressed growth of CT-genotyped tumours. And the knockdown of lncRNA-CCAT1 partly reversed the dysregulation of lncRNA-CCAT1 and FSCN1 mRNA/protein in rs67085638-CT + NC shRNA mice. The findings of this study demonstrated that the presence of the minor allele of rs67085638 increased the expression of CCAT1 and accordingly enhanced the resistance to PTX. Down-regulation of CCAT1 significantly re-stored the sensitivity to PTX of colon cancer cells.

Abstract
Long non-coding RNAs (lncRNAs) have been highlighted as prominent genetic modulators involved in multiple important biological processes of cancer cells, especially in esophageal cancer (EC). We tried to elucidate the potential role of LINC00337 in the progression of EC. Based on TCGA database analysis and Reverse transcription quantitative polymerase chain reaction determination, high expression of LINC00337 and FSCN1 was detected, while miR-145 exhibited a low expression in EC. LINC00337 was identified to bind to miR-145 to impair the miR-145-dependent FSCN1 inhibition. The underlying regulatory mechanisms were evaluated by transfection with LINC00337 overexpression plasmid, siRNA against LINC00337, miR-145 mimic, or anta-miR-145. Downregulation of LINC00337 results in increased Bax level, decreased FSCN1, Bcl-2, VEGF, and p53 levels, in addition to diminished cell proliferation, migration, invasion and tumor growth, with accelerated cell apoptosis by upregulating miR-145. Taken together, the findings obtained provided evidence suggesting that LINC00337 acts as a tumor promoter in EC, providing insight and advancements for EC treatment.

Abstract
The prognosis of breast cancer brain metastasis (BCBM) is extremely poor due to its resistance to conventional therapy. Elucidation of the molecular mechanisms of BCBM could contribute to the development of new therapeutic targets. In this study, we isolated RNA samples from primary breast cancer or BCBM, and then performed mRNA profiling. We determined that SOX2 is associated with the occurrence of BCBM and could be a predictor of BCBM. High levels of SOX2 were significantly associated with decreasing BCBM-free survival in patients. Overexpression of SOX2 in breast cancer cells enhanced cancer cell adhesion to brain microvascular endothelial cells, transendothelial migration, and in vitro blood-brain barrier (BBB) migration, whereas silencing SOX2 inhibited these events. SOX2 can increase cancer cell migration and BBB permeability by upregulating FSCN1 and HBEGF, thereby promoting BBB migration of breast cancer cells. Moreover, high levels of FSCN1 and HBEGF were significantly associated with reducing BCBM-free survival in breast cancer patients. Further study indicated that SOX2 mediates the expression of HBEGF and FSCN1 by activating AKT and β-catenin signaling pathways. Additionally, in vivo experiments showed that SOX2 promotes the development of BCBM. This study demonstrated that SOX2 promotes BCBM by upregulating the expression of FSCN1 and HBEGF.

Abstract
Drug resistance limits the efficacy of chemotherapy in human cancers. Previous studies reported that long noncoding RNA colon cancer-associated transcript 1 (CCAT1) regulated progression of prostate cancer (PCa). However, the potential role of CCAT1 in the sensitivity of paclitaxel (PTX) in PCa and its mechanism remain largely unknown. The PTX-resistant PCa cells were established in PC3 and DU145 cells by increasing concentrations of PTX. The expressions of CCAT1, microRNA-24-3p (miR-24-3p) and fascin1 (FSCN1) were measured by quantitative real-time polymerase chain reaction. The viability and apoptosis were detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay, flow cytometry and western blot, respectively. The interaction among CCAT1, miR-24-3p and FSCN1 was explored by luciferase activity, RNA immunoprecipitation, RNA pull-down and western blot, respectively. Results showed that the expressions of CCAT1 were up-regulated and miR-24-3p was down-regulated in PCa and PTX-resistant PCa cells (PC3-TXR and DU145-TXR). Knockdown of CCAT1 or overexpression of miR-24-3p inhibited survival rate, half maximal inhibitory concentration (IC50) of PTX but increased apoptosis in PC3-TXR and DU145-TXR cells after treatment of PTX. miR-24-3p was bound to CCAT1 and its abrogation reversed knockdown of CCAT1-mediated increase of PTX sensitivity in PC3-TXR and DU145-TXR cells. Moreover, FSCN1 restoration attenuated miR-24-3p-mediated inhibition of PTX resistance. Besides, FSCN1 level was enhanced in PCa and PTX-resistant PCa cells and regulated by CCAT1 and miR-24-3p. Our data suggested interference of CCAT1 contributed to PTX sensitivity in PCa by regulating miR-24-3p and FSCN1, indicating a novel avenue for treatment of PCa through regulating chemoresistance.

Abstract
FSCN1 gene encodes an actin-bundling protein, FSCN1, which is involved in formation of actin-based structures that contribute to cell migration. High levels of FSCN1 expression is observed in cells with extended membranes and protrusions. Moreover, up-regulation of FSCN1 has been reported in several epithelial carcinomas. Therefore, FSCN1 is thought to play a role in cell movement and invasion. However, the mechanism behind FSCN1 up-regulation is not known. We investigated the expression of FSCN1 using immunohistochemistry. Methylation-specific PCR was adopted to analyze the methylation status of FSCN1 promoter as a potential regulatory mechanism in FSCN1 expression. The samples included papillary thyroid carcinoma, follicular thyroid carcinoma and goiter samples (controls). Methylation of FSCN1 promoter was observed in 50% of follicular, 48.6% of papillary and 60% of controls. The promoter was unmethylated in 16.7% of follicular samples, 5.7% of papillary samples and 26.7% of controls. In the remaining 33.3% of follicular and 45.7% of papillary samples as well as 13.3% of controls, both methylated and unmethylated alleles were amplified, a condition referred to as semi-methylation. The results showed that FSCN1 promoter was significantly hypomethylated in papillary cases while the methylation status was not significantly altered in follicular cases. On the other hand, FSCN1 was expressed in only nine papillary samples. Regarding protein expression and methylation status, we suggest that hypomethylation of FSCN1 promoter in papillary thyroid carcinoma does not lead to overexpression of FSCN1 and that there might be other regulatory mechanisms involved in FSCN1 up-regulation.

Abstract
As a transcription coactivator, Yes-associated protein 1 (YAP1)'s role in tumorigenesis is well established. However, the mechanism of YAP1-regulating long noncoding RNAs (lncRNA) in tumors is still largely unknown. Here, a YAP1 target gene, long intergenic noncoding RNA 00152 (LINC00152), which is highly expressed in colorectal cancer (CRC), is identified. The oncogenic functions of LINC00152 in CRC are demonstrated by a panel of in vitro and in vivo experiments. Further studies reveal the potential downstream mechanisms of LINC00152, which can act as a competing endogenous RNA sponging with miR-632 and miR-185-3p to regulate Fascin actin-bundling protein 1 (FSCN1) expression and thus promote the malignant proliferation and metastasis in CRC cells. Targeting the YAP1/LINC00152/FSCN1 axis inhibits the progression of CRC. This finding provides a new regulatory model of the "YAP1-lncRNA" in CRC, which gives rise to a new perspective, "YAP1/LINC00152/miR-632-miR-185-3p/FSCN1," to explore the cancer-promoting mechanism of YAP1 involved in CRC.

Abstract
Long non-coding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) is correlated to various malignant tumors. Consequently, we explored effects of lncRNA PVT1 on esophageal carcinoma (EC) targeting microRNA-145 (miR-145). EC tissues, adjacent normal tissues, and EC-related cell lines were collected and cultured. Expression of lncRNA PVT1, miR-145, fascin-1 (FSCN1), and related genes with intervening expression of PVT1 and miR-145 was determined. Bioinformatic website, dual-luciferase reporter assay, and RNA immunoprecipitation (RIP) were carried to verify target relationship among lncRNA PVT1, FSCN1, and miR-145. Scratch test, Transwell assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and flow cytometry were performed for detection of migration, invasion, viability, and apoptosis of transfected cells, respectively. Finally, tumor formation in nude mice was measured. After database analysis, lncRNA PVT1, miR-145, and FSCN1 were selected for study. lncRNA PVT1 and FSCN1 can bind to miR-145. After overexpressing miR-145 or inhibiting lncRNA PVT1, EC cell viability, migration, and invasion were inhibited, while volume and weight of tumor formation in nude mice decreased. Expression of lncRNA PVT1, FSCN1, Bcl-2, CD147, VEGFR2, and MTA1 decreased and expression of miR-145 and Bax increased. Silencing lncRNA PVT1 can upregulate miR-145, which is a tumor suppressor in EC via knockdown of FSCN1. Thus, we might provide a potential theoretical basis for EC treatment.

Abstract
Accumulating evidence has established that long noncoding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) is a tumor regulator in many cancers. Here, we aimed to investigate the possible function of lncRNA PVT1 in esophageal carcinoma (EC) via targeting of microRNA-145 (miR-145). Initially, microarray-based gene expression profiling of EC was employed to identify differentially expressed genes. Moreover, the expression of lncRNA PVT1 was examined and the cell line presenting with the highest level of lncRNA PVT1 expression was selected for subsequent experiments. We then proceeded to examine interaction among lncRNA PVT1, FSCN1, and miR-145. The effect of lncRNA PVT1 on viability, migration, invasion, apoptosis, and tumorigenesis of transfected cells was examined with gain-of-function and loss-of-function experiments. We observed that lncRNA PVT1 was robustly induced in EC. lncRNA PVT1 could bind to miR-145 and regulate its expression, and FSCN1 is a target gene of miR-145. Overexpression of miR-145 or silencing of lncRNA PVT1 was revealed to suppress cell viability, migration, and invasion abilities, while also stimulating cell apoptosis. Furthermore, our in vivo results showed that overexpression of miR-145 or silencing of lncRNA PVT1 resulted in decreased tumor growth in nude mice. In conclusion, our research reveals that down-regulation of lncRNA PVT1 could potentially promote expression of miR-145 to repress cell migration and invasion, and promote cell apoptosis through the inhibition of FSCN1. This highlights the potential of lncRNA PVT1 as a therapeutic target for EC treatment.

Abstract
Background Adrenocortical carcinoma (ACC) is a rare malignant endocrine tumour. Due to a high tumour recurrence rate, the post-operative overall survival (OS) and disease-free survival (DFS) of ACCs is limited. Our research aims to identify the role of the epithelial-mesenchymal transition (EMT) related genes FSCN1 and FOXM1 in the tumour microenvironment and assess their prognostic value in ACCs. Methods Clinical and specimen data from 130 adrenocortical carcinoma (ACC) patients was acquired from the Cancer Genome Atlas (TCGA) database (n = 79) and a West China Hospital (WCH) cohort (n = 51). In the WCH cohort, archived formalin-fixed paraffin embedded (FFPE) samples were collected for immunohistochemical analysis. The correlation between the EMT genes and the tumour microenvironment status was estimated based on the Tumour Immune Estimation Resource (TIMER) algorithm. Kaplan-Meier analysis, followed by univariate and multivariate regression analyses, were performed to identify the prognostic association of FSCN1 and FOXM1. Results FSCN1 and FOXM1 were over-expressed in ACC tissue when compared with adrenocortical adenoma and normal adrenal tissue. Over-expression of FSCN1 or FOXM1 was associated with the tumour microenvironment and immune signatures in ACCs. Patients with higher expression of FSCN1 or FOXM1 were more likely to have worse prognoses. The prognostic effects were further verified in both early (stage I/II) and advanced (stage III/IV) ACCs. Furthermore, FSCN1 and FOXM1 appeared as independent prognostic factors in ACC. Conclusions These results show that FSCN1 and FOXM1 are independent prognostic factors in ACCs and over-expression of FSCN1 or FOXM1 indicates a worse prognosis.

Abstract
Much progress has been made in understanding the mechanism of acute lymphocytic leukemia (ALL). However, for adult ALL, there is still a lack of an effective treatment. In the present study, we first used the Gene Expression Omnibus (GEO) database to identify differentially expressed genes (DEGs) between ALL cell lines and Hodgkin and non-Hodgkin cell lines. Then, the GEO database was also used to detect the DEGs in acute lymphoblastic leukemia (Reh) cells transfected with a normal control or a constitutively active variant of the IkB kinase β. Finally, we found that three key DEGs (CCL5, FSCN1, and HS3ST1) are involved in proliferation and apoptosis according to Gene Ontology (GO) and Kyoto Encyclopedia of Genes Genomes (KEGG) pathway analyses. Finally, we determined that all three target genes that participate in proliferation and apoptosis are regulated via the NF-kB signaling pathway.

Abstract
Dysregulation of fascin actin-bundling protein 1 (FSCN1) enhances cell proliferation, invasion, and motility in laryngeal squamous cell carcinoma (LSCC), while the mechanism remains unclear. Here, co-immunoprecipitation and mass spectrometry is utilized to identify potential FSCN1-binding proteins. Functional annotation of FSCN1-binding proteins are performed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis. Furthermore, the protein-protein interaction network of FSNC1-binding proteins is constructed and the interactions between FSCN1 and novel identified interacting proteins AIMP1 and LTA4H are validated. Moreover, the expression and functional role of AIMP1 and LTA4H in LSCC are investigated. A total of 123 proteins are identified as potential FSCN1-binding proteins, and functional annotation shows that FSCN1-binding proteins are significantly enriched in carcinogenic processes, such as filopodium assembly-regulation and GTPase activity. Co-IP/western blotting and immunofluorescence confirm that AIMP1 and LTA4H bind and colocalize with FSCN1. Furthermore, both AIMP1 and LTA4H are upregulated in LSCC tissues, and knockdown of AIMP1 or LTA4H inhibits LSCC cell proliferation, migration, and invasion. Collectively, the identification of FSCN1-binding partners enhances understanding of the mechanism of FSCN1-mediated malignant phenotypes, and these findings indicate that FSCN1 binds to AIMP1 and LTA4H might promote the progression of LSCC.

Abstract
The purpose of our study was to investigate the underlying mechanism and functional role
of microRNA-145 (miR-145) in cervical cancer. In this study, quantitative real-time PCR
(qRT-PCR) was used to detect miR-145 and FSCN1 expression levels in tissues and HeLa
cells. Western blotting was performed to determine the protein level of FSCN1. The
luciferase assay was used to verify the direct target of miR-145. The CCK-8 assay and 2D
colony formation assays were performed to determine the effects of miR-145 mimics or FSCN1
silencing on cell proliferation. miR-145 expression levels were significantly
down-regulated, while FSCN1 expression levels were significantly up-regulated in the
cervical carcinoma tissues compared with their matched non-cancerous tissues. In addition,
FSCN1 expression levels were negatively correlated to miR-145 in tissues. Next, FSCN1 was
verified as the direct target of miR-145 in HeLa cells. Moreover, overexpression of
miR-145 dramatically inhibited the proliferation of HeLa cells. The silencing of FSCN1
exhibited the similar patterns on cell proliferation as miR-145 overexpression. The
miR-145/ FSCN1 axis contributes to the progression of cervical cancer by inhibition of
cervical cancer cell proliferation.

Abstract
Dairy cow mastitis is a detrimental factor in milk quality and food safety. Mastitis generally refers to inflammation caused by infection by pathogenic microorganisms. Our studies in recent years have revealed the role of miRNA regulation in Staphylococcus aureus-induced mastitis. In the present study, we overexpressed and suppressed miR-145 to investigate the function of miR-145 in Mac-T cells. Flow cytometry, ELISA and EdU staining were used to detect changes in the secretion of several Mac-T cytokines and in cell proliferation. We found that overexpression of miR-145 in Mac-T cells significantly reduced the secretion of IL-12 and TNF-α, but increased the secretion of IFN-γ; the proliferation of bovine mammary epithelial cells was also inhibited. Using quantitative real-time PCR (qRT-PCR), Western blotting and luciferase multiplex verification techniques, we found that miR-145 targeted and regulated FSCN1. Knock-down of FSCN1 significantly increased the secretion of IL-12, while the secretion of TNF-α was significantly downregulated in Mac-T cells. Upon S. aureus infection of mammary gland tissue, the body initiated inflammatory responses; Bta-miR-145 expression was downregulated, which reduced the inhibitory effect on the FSCN1 gene; and upregulation of FSCN1 expression promoted mammary epithelial cell proliferation to allow the recovery of damaged tissue. The results of the present study will aid in understanding the immune mechanism opposing S. aureus infection in dairy cows and will provide a laboratory research basis for the prevention and treatment of mastitis.

Abstract
Laryngeal squamous cell carcinoma (LSCC) is a common form of head and neck cancer with poor prognosis. However, the mechanism underlying the pathogenesis of LSCC remains unclear. Here, we demonstrated increased expression of fascin actin-bundling protein 1 (FSCN1) and decreased expression of microRNA-145-5p (miR-145-5p) in a clinical cohort of LSCC. Luciferase assay revealed that miR-145-5p is a negative regulator of FSCN1. Importantly, low miR-145-5p expression was correlated with TNM (tumor, node, metastasis) status and metastasis. Moreover, cases with low miR-145-5p/high FSCN1 expression showed poor prognosis, and these characteristics together served as independent prognostic indicators of survival. Gain- and loss-of-function studies showed that miR-145-5p overexpression or FSCN1 knockdown inhibited LSCC migration, invasion, and growth by suppressing the epithelial-mesenchymal transition along with inducing cell-cycle arrest and apoptosis. Additionally, hypermethylation of the miR-145-5p promoter suggested that repression of miR-145-5p arises through epigenetic inactivation. LSCC tumor growth in vivo could be inhibited by using miR-145-5p agomir or FSCN1 small interfering RNA (siRNA), which highlights the potential for clinical translation. Collectively, our findings indicate that miR-145-5p plays critical roles in inhibiting the progression of LSCC by suppressing FSCN1. Both miR-145-5p and FSCN1 are important potential prognostic markers and therapeutic targets for LSCC.

Abstract
Emerging evidence indicates that the dysregulation of long non-coding RNAs (lncRNAs) contributes to the development and progression of lung adenocarcinoma (LAD), however the underlying mechanism of action of lncRNAs remains unclear. It is well known that the effective treatment of cancers has been hindered by drug resistance in the clinical setting. Epithelial-mesenchymal transition (EMT) has been recognized to be involved in acquiring drug resistance, cell migration and invasion properties in several types of cancer. Docetaxel-resistant LAD cells established previously in our lab present chemoresistant and mesenchymal features. Long intergenic non-protein coding RNA, regulator of reprogramming (linc-ROR), was first discovered in induced pluripotent stem cells (iPSCs) and was upregulated in docetaxel-resistant LAD cells. In this study, we tried to make clarification of lincRNA-related mechanisms underlying EMT followed by acquired resistance to chemotherapy in LAD. In order to hit the mark, we made use of multiple methods including microarray analysis, qRT-PCR, western blotting analysis, loss/gain-of-function analysis, luciferase assays, drug sensitivity assays, wound-healing assay and invasion assay. We found that decreased expression of linc-ROR effectively reversed EMT in docetaxel-resistant LAD cells and sensitized them to chemotherapy. The function of linc-ROR exerted in LAD cells depended on the sponging of miR-145, therefore, releasing the miR-145 target FSCN1, and thus contributing to the acquisition of chemoresistance and EMT phenotypes of docetaxel-resistant LAD cells. Our findings revealed that linc-ROR might act as potential therapeutic target to overcome chemotherapy resistance in LAD.

Abstract
Background and objective In an attempt to discover a new biomarker for early diagnosis and prognosis of esophageal squamous cell carcinoma (ESCC), the regulation mechanism of large intergenic non-coding RNA–regulator of reprogramming (lincRNA-ROR) as a microRNA (miRNA) sponge was studied. Patients and methods ROR expression in 91 pairs of ESCC tissue samples and matched adjacent tissues was quantified with real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). The ROR–miRNA–mRNA regulatory network was built with 161 esophageal cancer (EC) tissues and 11 adjacent tumor tissues from The Cancer Genome Atlas (TCGA) database. A total of 96 cases of ESCC from TCGA database were collected for analysis on survival rates. The regulatory relationship between ROR, miR-145 and FSCN1 was verified in ESCC cells via qRT-PCR, dual luciferase reporter (DLR) assay, RNA immunoprecipitation (RIP) and Western blotting. The transwell method was used to detect cell migration and invasion. Results ROR expression in ESCC tumor tissues was significantly higher than in the adjacent tissues, p<0.001. The survival rate of ESCC patients with high ROR expression levels was lower than that of patients with low ROR expression levels (p<0.001). ROR overexpression could downregulate miR-145 by up to 50% was proven by RIP, DLR assay, and qRT-PCR. Two effective binding sites of ROR to miR-145 were verified by DLR assay. One of the sites has never been cited in the literature. The Western blotting results showed that FSCN1 was a downstream target of ROR/miR-145 (p<0.05). Transwell assays were used to show that overexpression of ROR enhanced migration and invasion behavior of ESCC and miR-145 hindered these effects. Conclusion ROR acted as a competitive endogenous RNA (ceRNA) of miR-145 in ESCC. A novel, effective miR-145 binding site of ROR was discovered. The ROR/miR-145/FSCN1 pathway was shown to take part in the metastasis of ESCC. ROR is likely an oncogene biomarker for ESCC early diagnosis and prognosis.

Abstract
While overexpression of FSCN1 is reported in several cancers, the prognostic significance of FSCN1 in renal cell carcinoma (RCC) and the molecular mechanisms involved remain largely unclear. We retrospectively enrolled 194 patients with non-metastatic clear-cell RCC undergoing nephrectomy in our center between 2008 and 2011. FSCN1 expression was assessed by immunohistochemical staining and its association with clinicopathologic features and survival were evaluated. Functional effects of a modulated FSCN1 expression were analyzed with regard to invasion in RCC cell lines and metastasis in vivo. Here, we reported that FSCN1 was up-regulated in RCC tissues compared to non-tumor tissues, and associated with poor overall survival and recurrence-free survival. Its expression was not associated with age, tumor size, and clinical TNM stage. The incorporation of FSCN1 into the T stage and histologic grade would help to refine individual risk stratification. Preclinical studies using multiple RCC cells and orthotopic xenografts mice model indicated that FSCN1 could promote RCC cell invasion in vitro, and metastasis in vivo. Mechanistically, overexpression of FSCN1 led to an up-regulation of MMP9 and N-Cadherin. Notably, treating RCC cells with PI3 K/AKT inhibitors or knockdown GSK-3β decreased the expression of FSCN1, and then attenuated RCC invasion. Together, our results demonstrate that FSCN as an oncogene is a potential novel prognostic biomarker for RCC patients after nephrectomy, and can promote RCC metastasis.

Abstract
Prostate cancer associated lncRNA transcript 1 (PCAT-1) has been identified as an oncogenic long non-coding RNA (lncRNA) in some solid tumors, including prostate cancer (PC). However, the molecular mechanism of PCAT-1 involved in PC is poorly defined. In this study, we found that PCAT-1 expression was up-regulated and miR-145-5p expression was down-regulated in PC tissues and cells. Function analysis indicated that PCAT-1 overexpression promoted proliferation, migration, invasion and inhibited apoptosis of PC cells. Rescue experiments demonstrated that miR-145-5p restoration attenuated the promotive effects of PCAT1 on PC progression, while Fascin-1 (FSCN1) upregulation relieved the anti-cancer role of miR-145-5p in PC. Mechanical analysis discovered that PCAT-1 could act as a miR-145-5p sponge to modulate FSCN1 expression. In conclusion, these findings suggested that PCAT-1 accelerated PC cell proliferation, migration, invasion and suppressed apoptosis by up-regulating FSCN1 mediated via miR-145-5p, hinting a potential therapeutic strategy for PC patients.

Abstract
In this study, we investigated whether there is any association between the expression of FSCN1 and SNAI2 and the possible underlying mechanisms in head and neck squamous cell carcinoma (HNSC). In addition, we also investigated whether FSCN1 modulates epithelial-to-mesenchymal transition (EMT) in HNSC cells. Microarray data of dysregulated genes in HNSC were searched in GEO datasets. The association between FSCN1 expression and the 5-year/10-year overall survival (OS), as well as the correlation between the expression of FSCN1 and SOX2, MYBL2, SNAI2, STAT1, and SOX4, was analyzed based on data in TCGA HNSC cohort (TCGA-HNSC). The binding site of SNAI2 in FSCN1 promoter was verified using luciferase reporter assay. SCC9 and SCC15 cells were transfected with pCMV-SNAI2 or pCMV-FSCN1 expression vector or the empty control. Alteration of E-cadherin, Claudin 1, Vimentin, and N-cadherin was then quantified. Our results showed that FSCN1 is significantly upregulated in HNSC tissues compared with the normal control tissues. High FSCN1 expression is associated with worse 5-year and 10-year OS among the HNSC patients. Bioinformatic prediction showed a highly possible SNAI2 binding site in FSCN1 promoter and following luciferase reporter assay verified this site. SNAI2 overexpression significantly increased FSCN1 expression at both mRNA and protein level. FSCN1 overexpression reduced the expression of E-cadherin and Claudin 1, but increased the expression of Vimentin and N-cadherin in SCC9 and SCC-15 cells. Therefore, we infer that FSCN1 is a downstream effector of SNAI2 in promoting EMT in HNSC cells.

Abstract
To date, several cell proliferation markers, apoptosis, vascular markers, oncogenes, tumor suppressor genes, cell cycle mediators, microRNA (miRNAs), and long noncoding RNAs (lncRNAs) have been identified to be involved in the tumorigenesis, migration, proliferation and invasiveness of pituitary adenomas. There are still no reliable morphologic markers predictive of pituitary adenoma recurrence. Recent scientific research introduced new techniques to enable us to attain new information on the genesis and biologic behavior of pituitary adenomas. Areas covered: This review covers selected, compelling and cumulative information in regards to TACSTD family (EpCAM, TROP2), neuropilin (NRP-1), oncogene-induced senescence (OIS), fascins (FSCN1), invasion-associated genes (CLDN7, CNTNAP2, ITGA6, JAM3, PTPRC and CTNNA1) EZH2, and ENC1 genes and endocan. Expert commentary: Ongoing research provides clinicians, surgeons and researchers with new information not only on diverse pathways in tumorigenesis but also on the clinical aggressive behavior of pituitary adenomas. Newly developed molecular techniques, bioinformatics and new pharmaceutical drug options are helpful tools to widen the perspectives in our understanding of the complex nature of pituitary tumorigenesis. The discovery of new molecular biomarkers can only be accomplished by continuing to investigate pituitary embryogenesis, histogenesis and tumorigenesis.

Abstract
It has been previously reported that the deregulation of microRNAs in gastric cancer (GC) was correlated with the progression and prognosis. miR-429, a member of the miR-200 family, was previously shown to play an important role in human carcinomas. Our study shows that miR-429 is significantly downregulated in GC tissues compared with matched nontumor tissues. Overexpression of miR-429 in GC cells suppressed cell proliferation. Fascin-1 (FSCN1) was identified as one of the targets of miR-429 and knockdown of FSCN1 mimics the function of miR-429 overexpression. In conclusion, miR-429 acts as a tumor suppressor by targeting FSCN1, suggesting that miR-429 and FSCN1 can both be potential therapeutic targets of GC.

Abstract
The prediction of invasion or malignant behavior in PAs remains challenging. FSCN1, an actin-bundling protein, is associated with increased risk of mortality and metastasis in various cancer types. The objective of the study was to evaluate the expression of FSCN1 in 312 PAs cases, and to analyze its association with clinicopathologic features and invasion of PAs, thus serving as a promoter of cancer invasion. In non-function PAs (NFPA), FSCN1 nuclear-positive cases were 53/97 in the invasive group (IPA), and 21/115 in the noninvasive group (nIPA) (ⅹ(2) = 30.65, p = 0.004). FSCN1 cytoplasm-positive cases were 36/97 in IPA, and 8/107 in nIPA (ⅹ(2) = 29.09, p = 0.000). In growth hormone adenomas (GHomas), FSCN1 nuclear-positive were 10/13 in IPA, and 3/37 in nIPA (ⅹ(2) = 23.67, p = 0.000). FSCN1 cytoplasm-positive were 8/13 in IPA, and 2/37 in nIPA (Table 3 ⅹ(2) = 18.94, p = 0.000). Overall, a significant difference was found between FSCN1 expression and tumor size (ⅹ(2) = 46.21, p = 0.000), not age (ⅹ(2) = 2.09, p = 0.148). In the high FSCN1 expression group, 27/137 cases (19.7%) had tumor recurrence, and 10/175 cases (5.7%) in low FSCN1 level (ⅹ(2) = 14.40 p = 0.000). Reduction of FSCN1 suppressed the invasion level of GH3 cells through transwells test. In addition, reduction of FSCN1 can obviously down-regulate the level of Notch1 and DLL3. Our data may help in deciding whether FSCN1 can be a predictor for invasion and recurrence of PAs.

Abstract
BACKGROUND Deregulation of FSCN1 has been observed in human cancers. However, the regulatory mechanism of FSCN1 in hepatocellular carcinoma (HCC) remains largely unknown. AIMS Our study aimed to reveal the roles of microRNA (miR)-133a, miR-145, and FSCN1 in HCC cells. METHODS Real-time RT-PCR and western blot were performed to determine the expression of miR-133a, miR-145, and FSCN1. Luciferase reporter assay was used to determine whether FSCN1 was a target of miR-133a and miR-145. Effects of miR-133a, miR-145, and FSCN1 on HCC cell proliferation, apoptosis, migration, and invasion were then investigated. RESULTS We showed that the expression of FSCN1 was increased in HCC tissues compared to the normal adjacent tissues. Moreover, upregulation of FSCN1 and downregulation of miR-145 and miR-133a co-existed in HCC. Functional studies revealed that miR-145 and miR-133a negatively regulated the expression of FSCN1 in HCC cells, via directly binding to the 3'-untranslational region of FSCN1 mRNA. Overexpression of miR-145 and miR-133a led to decreased FSCN1 expression, and downregulation of miR-145 and miR-133a resulted in increased FSCN1 expression in HCC cells. Furthermore, overexpression of miR-145 and miR-133a inhibited cellular proliferation, migration, and invasion, while promoted apoptosis in HCC cells. On the contrary, inhibition of miR-145 and miR-133a promoted cellular proliferation, migration, and invasion, while suppressed apoptosis in HCC cells. CONCLUSION Our study suggests that the abnormal upregulation of FSCN1 in HCC is associated with downregulation of miR-145 and miR-133a, and miR-145 and miR-133a inhibit malignant progression of HCC in vitro, possibly via directly targeting FSCN1.

Abstract
BACKGROUND The extraordinary invasive capability is a major cause of treatment failure and tumor recurrence in lung cancer. Evidence in other cell systems has implicated the regulatory role of microRNA-145 in cell motility and invasion, which promotes us to investigate the biological functions of miR-145 in lung cancer in this regard. RESULTS We have found that miR-145 is dramatically down-regulated in clinical specimen of lung cancer and is negatively correlated with the tumor pathological grading in the current study. The cells transfected by miR-145 expression vector have demonstrated retarded cell mobility. Using a bioinformatics analysis approach, fascin homolog 1 (FSCN1), actin-binding protein, has been identified as the target of miR-145. Over-expression of miR-145 mimics enhanced protein levels of E-cadherin and fibronectin, indicative of its inhibitory role in EMT occurrence. Mechanistic studies showed that miR-145 mimics inhibited FSCN1 expression and miR-145 inhibitor enhanced it. Over-expression of FSCN1 reversed miR-145-regulated expression of EMT markers, suggesting that FSCN1 mediated the inhibitory effects of miR-145. Our results revealed a novel mechanism that miR-145 inhibits lung cancer cells migration and invasion via FSCN1 downregulation. CONCLUSIONS These results suggest that miR-145 may function as anti-migration and anti-invasion influence in lung cancer and provides a potential approach for developing miR-145-based therapeutic strategies for malignant lung cancer therapy.

Abstract
BACKGROUND MicroRNAs (miRNAs) have been documented as playing important roles in diverse biological processes including tumorigenesis. However, the function and mechanism of miR-326 in gastric cancer are still unknown. The aim of this study is to identify the role of miR-326 in gastric cancer and clarify the regulation of Fascin1 (FSCN1) by miR-326. METHODS The expression levels of miR-326 were detected in gastric cancer samples and cell lines by real-time PCR. The clinical and prognostic significance of miR-326 in gastric cancer patients were analyzed. Furthermore, the function of miR-326 on tumor cell growth and mobility were explored through MTT, colony formation, Transwell migration and invasion assays in vitro. A miR-326 target was confirmed using luciferase reporter assays, real-time PCR and Western blot. RESULTS Our study showed that miR-326 expression was decreased in gastric cancer tissues and cell lines, and low expression of miR-326 was associated to clinical stage, tumor depth, lymph node metastasis and distant metastasis. In survival analysis, low expression of miR-326 was a poor independent prognostic factor for gastric cancer patients. Gain-of-function and loss-of-function studies showed that miR-326 served as a tumor suppressor regulating gastric cancer cells growth, migration and invasion. Furthermore, we identified FSCN1 as the functional target of miR-326 by directly targeting the 3'-UTR of FSCN1. CONCLUSIONS Our study demonstrated that miR-326 overexpression was a poor prognostic marker for gastric cancer patients, and miR-326 served as a tumor suppressor in gastric cancer via directly regulating FSCN1.

Abstract
BACKGROUND MicroRNAs (miRNAs) are a class of small, well-conserved, non-coding RNAs that regulate the translation of RNAs. They have a role in biological and pathological process including cell differentiation, apoptosis, proliferation and metabolism. Since their discovery, they have been shown to have a potential role in cancer pathogenesis through their function as oncogenes or tumor suppressors. A substantial number of miRNAs show differential expression in esophageal cancer tissues, and so have been investigated for possible use in diagnosis. Furthermore, there is increasing interest in their use as prognostic markers and determining treatment response, as well as identifying their downstream targets and understanding their mode of action. METHODS We analyzed the most recent studies on miRNAs in esophageal cancer and/or Barrett's esophagus (BE). The publications were identified by searching in PuBMed for the following terms: Barrett's esophagus and microRNA; esophageal cancer and microRNA. RESULTS Four miRNAs (mi-R-25, -99a, -133a and -133b) showed good potential as diagnostic markers and interestingly five (mi-R-21, -27b, -126, - 143 and -145) appeared to be useful both as diagnostic and prognostic/predictive markers. CONCLUSION The data so far on miRNAs in esophageal carcinogenesis is promising but further work is required to determine whether miRNAs can be used as biomarkers, not only in the clinical setting or added to individualized treatment regimes but also in non-invasive test by making use of miRNAs identified in blood.

Abstract
The earlier studies have shown that Fascin1 (FSCN1), the actin bundling protein, is over-expressed in colorectal cancers, and is associated with cancer cell progression. Here, we aimed to understand the molecular mechanisms regulating FSCN1 expression by focusing on mammalian target of rapamycin (mTOR) signaling and its regulator microRNA-451. We found that microRNA-451 was over-expressed in multiple colorectal cancer tissues, and its expression was correlated with mTOR complex 1 (mTORC1) activity and FSCN1 expression. In cultured colorectal cancer HT-29 cells, knockdown of FSCN1 by RNAi inhibited cell migration and proliferation. Activation of mTORC1 was required for FSCN1 expression, HT-29 cell migration and proliferation, as RAD001 and rapamycin, two mTORC1 inhibitors, suppressed FSCN1 expression, HT-29 cell migration and proliferation. Meanwhile, forced activation of AMP-activated protein kinase (AMPK), the negative regulator of mTORC1, by its activators or by the genetic mutation, inhibited mTORC1 activation, FSCN1 expression, cell migration and proliferation. In HT-29 cells, we found that over-expression of microRNA-451 inhibited AMPK activation, causing mTORC1 over-activation and FSCN1 up-regulation, cells were with high migration ability and proliferation rate. Significantly, these effects by microRNA-451 were largely inhibited by mTORC1 inhibitors or the AMPK activator AICAR. On the other hand, knockdown of miRNA-451 by the treatment of HT-29 cells with miRNA-451 antagomir inhibited mTORC1 activation and FSCN1 expression. The proliferation and migration of HT-29 cells after miRNA-45 knockdown were also inhibited. Our results suggested that the over-expressed microRNA-451 in colon cancer cells might inhibit AMPK to activate mTORC1, which mediates FSCN1 expression and cancer cell progression.
