Abstract
Protein arginine methylation is among the most important post-translational modifications and has been studied in cancers such as those of the lung and breast. However, comparatively less has been investigated regarding hepatocellular carcinoma, with an annual incidence of almost one million cases. Through using in silico methods, this study examined arginine methylation-related gene expression and methylation levels, and alongside network and enrichment analysis attempted to find how said genes can drive tumorigenesis and offer possible therapeutic targets. We found a robust relationship among the selected methylation genes, with ⅞ showing prognostic value regarding overall survival, and a medley of non-arginine methylation pathways also being highlighted through the aforementioned analysis. This study furthers our knowledge of the methylation and expression patterns of arginine histone methylation-related genes, offering jumping points for further wet-lab studies.

A conserved ZFX/WNT3 axis modulates the growth and imatinib response of chronic myeloid leukemia stem/progenitor cells. Cell Mol Biol Lett 2023; 28:83. [PMID: 37864206 PMCID: PMC10589942 DOI: 10.1186/s11658-023-00496-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Accepted: 10/03/2023] [Indexed: 10/22/2023] Open
Abstract
BACKGROUND Zinc finger protein X-linked (ZFX) has been shown to promote the growth of tumor cells, including leukemic cells. However, the role of ZFX in the growth and drug response of chronic myeloid leukemia (CML) stem/progenitor cells remains unclear. METHODS Real-time quantitative PCR (RT-qPCR) and immunofluorescence were used to analyze the expression of ZFX and WNT3 in CML CD34+ cells compared with normal control cells. Short hairpin RNAs (shRNAs) and clustered regularly interspaced short palindromic repeats/dead CRISPR-associated protein 9 (CRISPR/dCas9) technologies were used to study the role of ZFX in growth and drug response of CML cells. Microarray data were generated to compare ZFX-silenced CML CD34+ cells with their controls. Chromatin immunoprecipitation (ChIP) and luciferase reporter assays were performed to study the molecular mechanisms of ZFX to regulate WNT3 expression. RT-qPCR and western blotting were used to study the effect of ZFX on β-catenin signaling. RESULTS We showed that ZFX expression was significantly higher in CML CD34+ cells than in control cells. Overexpression and gene silencing experiments indicated that ZFX promoted the in vitro growth of CML cells, conferred imatinib mesylate (IM) resistance to these cells, and enhanced BCR/ABL-induced malignant transformation. Microarray data and subsequent validation revealed that WNT3 transcription was conservatively regulated by ZFX. WNT3 was highly expressed in CML CD34+ cells, and WNT3 regulated the growth and IM response of these cells similarly to ZFX. Moreover, WNT3 overexpression partially rescued ZFX silencing-induced growth inhibition and IM hypersensitivity. ZFX silencing decreased WNT3/β-catenin signaling, including c-MYC and CCND1 expression. CONCLUSION The present study identified a novel ZFX/WNT3 axis that modulates the growth and IM response of CML stem/progenitor cells.

Abstract
OBJECTIVES Although great progress has made in gastric cancer (GC) in the past years, the overall 5-year survival rate remains to be low for advanced GC patients. A recent study showed that PLAGL2 was increased in GC and enhanced the proliferation and metastasis of GC. Nevertheless, the underlying mechanism still needs to be investigated. METHODS Gene and protein expressions were assessed using RT-qPCR and western blot. The migration, proliferation and invasion of GC cells were examined using scratch assay, CCK-8 assay and Transwell assay, respectively. ChIP-PCR, dual-luciferase assay, RIP-qPCR and CoiP were utilized to confirm the interaction among PLAGL2, UCA1, miR-145-5p and YTHDF1 as well as METTL3, YTHDF1 and eEF-2. A mouse xenograft model was used utilized to further confirm the regulatory network. RESULTS PLAGL2 bound to the upstream promoter of UCA1, which regulated YTHDF1 by sponging miR-145-5p. METTL3 can mediate the m6A modification level of Snail. YTHDF1 recognized m6A-modified Snail by interacting with eEF-2 and thus promoted Snail expression, which eventually induced epithelial-mesenchymal transition (EMT) in GC cells and metastasis of GC. CONCLUSIONS Overall, our study demonstrates that PLAGL2 enhances Snail expression and GC progression via the UCA1/miR-145-5p/YTHDF1 axis, suggesting that PLAGL2 may become a therapeutic target for GC treatment.

Abstract
According to the 2020 global cancer data released by the World Cancer Research Fund (WCRF) International, gastric cancer (GC) is the fifth most common cancer worldwide, with yearly increasing incidence and the second-highest fatality rate in malignancies. Despite the contemporary ambiguous molecular mechanisms in GC pathogenesis, numerous in-depth studies have demonstrated that zinc finger proteins (ZFPs) are essential for the development and progression of GC. ZFPs are a class of transcription factors with finger-like domains that bind to Zn2+ extensively and participate in gene replication, cell differentiation and tumor development. In this review, we briefly outline the roles, molecular mechanisms and the latest advances in ZFPs in GC, including eight principal aspects, such as cell proliferation, epithelial-mesenchymal transition (EMT), invasion and metastasis, inflammation and immune infiltration, apoptosis, cell cycle, DNA methylation, cancer stem cells (CSCs) and drug resistance. Intriguingly, the myeloid zinc finger 1 (MZF1) possesses reversely dual roles in GC by promoting tumor proliferation or impeding cancer progression via apoptosis. Therefore, a thorough understanding of the molecular mechanism of ZFPs on GC progression will pave the solid way for screening the potentially effective diagnostic indicators, prognostic biomarkers and therapeutic targets of GC.

Abstract
Background: Growing evidence demonstrated that long noncoding RNAs (lncRNAs) were involved in the progression of diverse cancers, including breast cancer (BC). Recent studies indicated that lncRNA nuclear enriched abundant transcript 1 (NEAT1) was overexpressed and facilitated tumor processes in many cancers. Nevertheless, the underlying mechanism of NEAT1 in regulating BC progression is still largely unknown. Materials and Methods: The abundance of NEAT1, microRNA-138-5p (miR-138-5p), and zinc finger protein X-linked (ZFX) was assessed by quantitative real-time polymerase chain reaction. Cell Counting Kit-8 (CCK-8) assay, flow cytometry, and transwell assay were utilized to evaluate cell proliferation, apoptosis, migration, and invasion, respectively. Western blot analysis was applied to detect the protein expression of CyclinD1, Bax, E-cadherin, and ZFX. The interaction between miR-138-5p and NEAT1 or ZFX was predicted by starBase v3.0 and validated by dual-luciferase reporter, RNA pull-down, and RNA immunoprecipitation assays. The mice xenograft model was established to investigate the roles of NEAT1 in vivo. Results: NEAT1 was highly expressed and miR-138-5p was lowly expressed in BC tissues and cells. NEAT1 interference or miR-138-5p restoration repressed cell proliferation, migration, and invasion but accelerated apoptosis in BC cells. Moreover, miR-138-5p directly interacted with NEAT1 and its knockdown reversed the suppressive impact of NEAT1 downregulation on the progression of BC cells. In addition, ZFX was a downstream target of miR-138-5p and its upregulation attenuated the antitumor role of miR-138-5p in BC cells. Besides, ZFX expression was positively regulated by NEAT1 and inversely modulated by miR-138-5p. Furthermore, interference of NEAT1 inhibited tumor growth by upregulating miR-138-5p and downregulating ZFX. Conclusion: NEAT1 affected BC progression through modulating miR-138-5p/ZFX axis, providing a vital theoretical basis for BC treatment.

Abstract
The dormant population of ovarian primordial follicles is determined at birth and serves as the reservoir for future female fertility. Yet our understanding of the molecular, biochemical, and cellular processes underpinning primordial follicle activation remains limited. The survival of primordial follicles relies on the correct complement and morphology of granulosa cells, which provide signaling factors essential for oocyte and follicular survival. To investigate the contribution of granulosa cells in the primordial-to-primary follicle transition, gene expression profiles of granulosa cells undergoing early differentiation were assessed in a murine model. Ovaries from C57Bl/6 mice were enzymatically dissociated at time-points spanning the initial wave of primordial follicle activation. Post-natal day (PND) 1 ovaries yielded primordial granulosa cells, and PND4 ovaries yielded a mixed population of primordial and primary granulosa cells. The comparative transcriptome of granulosa cells at these time-points was generated via Illumina NextSeq 500 system, which identified 131 significantly differentially expressed transcripts. The differential expression of eight of the transcripts was confirmed by RT-qPCR. Following biological network mapping via Ingenuity Pathway Analysis, the functional expression of the protein products of three of the differentially expressed genes, namely FRZB, POD1, and ZFX, was investigated with in-situ immunolocalization in PND4 mouse ovaries was investigated. Finally, evidence was provided that Wnt pathway antagonist, secreted frizzled-related protein 3 (FRZB), interacts with a suppressor of primordial follicle activation WNT3A and may be involved in promoting primordial follicle activation. This study highlights the dynamic changes in gene expression of granulosa cells during primordial follicle activation and provides evidence for a renewed focus into the Wnt signaling pathway’s role in primordial follicle activation.

Abstract
INTRODUCTION Zinc finger X-chromosomal protein (ZFX) has been shown to be essential for the development and progression of multiple types of human cancers. However, its potential roles in esophageal squamous cell carcinoma (ESCC) have not yet been elucidated. MATERIALS AND METHODS Eighty-three pairs of frozen ESCC samples and their para-cancer samples and 24 fresh ESCC samples were collected. In vitro chemosensitivity was tested using the histoculture drug response assay. Quantitative RT-PCR and western blotting were used to measure the expression of functional genes. The effects of ZFX on cell growth, cell apoptosis, and chemosensitivity of the esophageal cancer cells were assessed. RESULTS We found that ZFX was more upregulated in ESCC tissues than in the para-cancer tissues, and its high expression was correlated with inferior clinicopathological characteristics and overall survival. Multivariate analysis revealed that ZFX was an independent prognostic factor in ESCC patients. In ESCC cell lines, ZFX silencing suppressed cell growth and induced cell apoptosis. In addition, ZFX expression was negatively correlated with the sensitivity of fresh ESCC tissues to chemotherapeutic drugs, including cisplatin, docetaxel, fluorouracil, and irinotecan. Furthermore, the depletion of ZFX sensitized ESCC cells to cisplatin, and docetaxel treatment. Mechanistically, ZFX silencing resulted in the inactivation of the MEK/ERK pathway, which mediated the downregulation of P-glycoprotein expression. CONCLUSION Our study therefore indicates that ZFX possibly plays a critical role in ESCC tumorigenesis and chemotherapy resistance and could be a significant prognostic biomarker and therapeutic target for ESCC.

Abstract
BACKGROUND Gastric cancer (GC) remains a major global health problem due to a poor understanding of its progression at the molecular level and a lack of early detection or diagnosis. Early detection is highly crucial for improving prognosis. The incidence of GC is very high in countries like India due to the limitations among the established biomarkers for GC owing to poor sensitivity and specificity. OBJECTIVE To identify the novel biomarkers from serum samples obtained from GC patients when compared with healthy subjects. METHODS Serum samples from GC patients were analyzed by two-dimensional gel electrophoresis (2DGE) coupled with tandem mass spectrometry (MS), including both matrix-assisted laser desorption/ionization-time of flight (MALDI-ToF) and liquid chromatography-MS (LC-MS/MS) analysis. Identified proteins were further analyzed by gene ontology and protein interaction studies. RESULTS A total of 73 protein spots were detected in 2DGE image analysis. Among them, seven differentially-expressed proteins were identified using MS analyses, which included serotransferrin/transferrin, albumin, ceruloplasmin, C-reactive protein (CRP), fibrinogen γ-chain (FGG), and two unreported novel proteins, immunoglobulin kappa constant (IgκC) region and Homo sapiens zinc finger protein 28 (ZNF28) homolog. Among these proteins, serotransferrin, albumin, ceruloplasmin, FGG, and ZNF28 were down-regulated in GC samples (p < 0.05), while IgκC region and CRP were up-regulated significantly. CONCLUSION Most of the differentially expressed proteins were involved in angiogenesis, plasminogen-activating cascade, and blood coagulation pathways which are known to play a critical role in gastric tumorigenesis. Our current results provide a panel of candidate biomarkers for GC with novel biomarkers which were not reported earlier.

Abstract
Emerging documents revealed that E2 enzyme family has been implicated in regulating the progression of numerous human cancers. Ubiquitin-conjugating enzyme E2 J1 (UBE2J1), a member of E2 enzyme family, has been reported to participate in the biological process of medulloblastoma, while little is known about its functionality in endometrial cancer (EC). Gene expression at the mRNA and protein levels were identified using RT-qPCR and western blot analysis, separately. The alteration on cell proliferation, adhesion, migration, invasion, and epithelial-mesenchymal transition (EMT) process was determined through 5-Ethynyl-2'-deoxyuridine, cell adhesion, wound healing and transwell assays as well as western blot analysis. The role of UBE2J1 in xenograft tumor in mice was determined. Luciferase reporter and chromatin immunoprecipitation assays were conducted to reveal the undering mechanism of UBE2J1. Our results indicated that UBE2J1 displayed high level in EC tissues and cells and predicted poor prognosis of EC patients. In addition, UBE2J1 depletion inhibited cell proliferation, adhesion, motion, EMT process invitro, and repressed tumor growth invivo. Rescue assays manifested that ethyl 2-amino-6-chloro-4-(1-cyano-2-ethoxy-2-oxoethyl)-4H-chromene-3-carboxylate treatment reversed the effects of UBE2J1 on PI3K/AKT pathway activation and malignant phenotypes of EC cells. Finally, zinc finger X-chromosomal protein (zfx), with high expression in EC tissues, was verified to activate UBE2J1 transcription by binding to UBE2J1 promoter. In conclusion, all facts signified that zfx-induced upregulation of UBE2J1 accelerated the progression of EC via regulating the PI3K/AKT signaling pathway, which suggested that UBE2J1 might be of great significance in probing into the underlying therapeutic strategies of EC.

Abstract
Abstract
Background
Lung adenocarcinoma is metastatic cancer with a high mortality rate. Circular RNAs (circRNAs) are a type of noncoding RNA and play a vital role in cancer progression. However, the expression and function of circRNAs in lung adenocarcinoma are still mostly unknown.
Methods
In this study, we screened the differential expression of circRNAs in human bronchial epithelial cells (HBE) and A549 human lung adenocarcinoma cell line (A549) by human circRNA microarray and RT-qPCR. The role of overexpressed circRNA_104889 in A549 cell proliferation, apoptosis, migration, and invasion was studied extensively. Intracellular localization of circRNA_104889 was visualized by FISH assay. MiRNA sponging, ERK1/2 signaling, and caspase-3 expression were analyzed in siRNA-mediated circRNA_104889 knockdowned A549 cells.
Results
CircRNA microarray showed overexpression of circRNA_104889 (> 13-fold) in A459 cells compared to HBE. This finding was further corroborated by the RT-qPCR result. CircRNA_104889 was mainly localized in the cytoplasm of A549 cells. The knockdown of circRNA_104889 in A549 cells by si-RNA mediated RNA interference did not affect cell proliferation and apoptosis but significantly inhibited cell migration and invasion in vitro. Furthermore, knockdown of circRNA_104889 led to an increase of miR4458 expression. Overexpression of miR4458 inhibited A549 cell migration. Both the knockdown of circRNA_104889 and overexpression of miR4458 inhibited the caspase-3 expression and ERK1/2 phosphorylation in A549 cells.
Conclusions
CircRNA_104889 promotes lung adenocarcinoma cell migration and invasion by sponging miR4458 and targeting ERK1/2 signaling and caspase-3 expression.

CCAT1 promotes triple-negative breast cancer progression by suppressing miR-218/ZFX signaling. Aging (Albany NY) 2020; 11:4858-4875.

Abstract
Long non-coding RNAs (lncRNAs) regulate cancer development and progression. Here, we investigated the role of the lncRNA CCAT1 in triple-negative breast cancer (TNBC). CCAT1 expression was higher in TNBC cells than normal breast epithelial cells. Additionally, CCAT1 expression was higher in TNBC patient tumor tissue than adjacent normal breast tissue. Silencing CCAT1 inhibited TNBC cell proliferation, migration, and invasion in vitro, and tumor growth and progression in vivo. Bioinformatics analysis revealed that microRNA-218 (miR-218) is a potential target of CCAT1. Silencing CCAT1 resulted in an increase in miR-218 expression and inhibited TNBC cell proliferation, migration, and invasion. Silencing miR-218 reversed the effects of CCAT1 knockdown on cell proliferation, migration, and invasion, suggesting that CCAT1 promotes TNBC progression by downregulating miR-218 expression. We identified the zinc finger protein ZFX as a putative downstream target of miR-218 through bioinformatics analysis. ZFX expression was higher in TNBC than normal breast cell lines and higher in TNBC tumor tissue than adjacent normal breast tissue. Overexpression of ZFX reversed the tumor-suppressive effects of miR-218 on TNBC cell proliferation, migration, and invasion. Our data indicate that CCAT1 promotes TNBC progression by targeting the miR-218/ZFX axis.

Abstract
Background HOXA cluster antisense RNA2 (HOXA-AS2), a long-chain non-coding RNA, plays an important role in the behavior of various malignant tumors. The roles of HOXA-AS2 in endometrial cancer remain unclear. Methods We test expression levels of HOXA-AS2, miRNA-302c-3p, the transcription factor zinc finger X-chromosomal protein (ZFX), and the chitinase-like protein YKL-40 in endometrial carcinoma by qRT-PCR and western blotting. Luciferase reporter and qRT-PCR assays were conducted to identify potential binding sites of HOXA-AS2 to miRNA-302c-3p. Cell cycle, migration and invasion ability of endometrial cancer cells were investigated using flow-cytometric analysis, CCK-8 and transwell assays, respectively. Results HOXA-AS2 levels were significantly increased in endometrial cancer specimens compared to normal endometrial specimens. Upregulated HOXA-AS2 promoted invasion and proliferation of type I endometrial cancer cells. HOXA-AS2 silenced miRNA-302c-3p by binding to it. MiRNA-302c-3p negatively regulates ZFX and YKL-40. Thus HOXA-AS2 promotes the development of type I endometrial cancer via miRNA-302c-3p-mediated regulation of ZFX. Conclusions These findings suggest that HOXA-AS2 can act as a new therapeutic target for type I endometrial cancer.

Expressions of ezrin, ERK, STAT3, and AKT in tongue cancer and association with tumor characteristics and patient survival. Clin Exp Dent Res 2020; 6:420-427.

Abstract
Background Ezrin, ERK, STAT3, and AKT are proteins that are overexpressed in various types of cancer, although their expressions in tongue cancer has received less focus. This study aimed to address associations between the expression levels of these proteins and with characteristics of the tumor and patient survival. Methods We performed immunohistochemical staining of ezrin, ERK, STAT3, and AKT in tumors from patients with tongue carcinoma in situ (CIS, n = 17) and tongue squamous cell carcinoma (SCC, n = 46). Statistical differences between the SCC versus the CIS cohorts were estimated by calculations of bivariate odds ratios of low versus high expression of the proteins. Fisher's exact tests were used to appraise interassociations between the proteins, as well as expression levels versus patient and tumor characteristics. Survival based on Kaplan–Meier statistics in combination log‐rank tests were used to address potential effects of the patient and tumor characteristics versus 5‐year survival rate. Results The relative high: low expression of all four proteins in the two cohorts differed, and particularly ERK was markedly overexpressed in the SCC versus the CIS cohort (odds ratio = 45.3, p < .01). The relative high: low expression each protein versus patient and tumor characteristics; showed associations between AKT expression and T stage (p = .002) plus node metastases (p = .12), and between ERK expression and drinking (p = .01) and smoking history (p = .01). There was no significant difference observed between ERK and the three other molecules, nor any significant difference between the degree of expression of each protein and the 5‐year disease‐specific survival rate. Conclusion Ezrin, ERK, STAT3, and AKT appear to be involved in the progress from carcinoma in situ in the tongue into squamous cell carcinoma. ERK in particular is overexpressed, suggesting that ERK may be a novel therapeutic target for preventing tongue cancer.

Abstract
BACKGROUND Long non-coding RNAs are important regulators in cancer cell tumorigenesis. We have demonstrated in a prior study that lncRNA FTX is dysregulated in gastric cancer (GC). In this study, we aim to report gastric cancer-related lncRNA FTX as a main regulator in GC development and progression. METHODS In vitro and in vivo assays of FTX alterations have been performed to reveal a complex integrated phenotype affecting cell growth, migration, and invasion. lncRNA FTX expression levels in gastric cancer cells and normal cells were measured by RT-PCR. Luciferase reporter assays, Western blotting, and many immune, microscopy technologies were utilized to investigate the expressions of FTX- related proteins and RNAs. The functional role of FTX in cell growth, migration, and invasion were observed in vitro and in vivo. RESULTS We explored the underlying mechanisms of FTX in GC development, and the microRNAs' relationship with FTX. We found that FTX promoted cell proliferation, migration, and invasion, as well as tumor growth, and this effect could latterly be attenuated by miR-144. ZFX attenuated the effects of FTX/miR-144 axis by sponging with miR-144. CONCLUSION In summary, the above results support a model in which the FTX/miR-144/ZFX act as important effectors in GC tumorigenesis and progression, indicating new therapeutic methods in GC.

Abstract
Background A healthy gastric mucosal epithelium exhibits tumor-suppressive properties. Gastric epithelial cell dysfunction contributes to gastric cancer development. Oxysterols provided from food or cholesterol oxidation in the gastric epithelium may be further sulfated by hydroxysteroid sulfotransferase 2B1 (SULT2B1), which is highly abundant in the gastric epithelium. However, the effects of SULT2B1 on gastric epithelial function and gastric carcinogenesis are unclear. Methods A mouse gastric tumor model was established using carcinogenic agent 3-methylcholanthrene (3-MCA). A SULT2B1 deletion (SULT2B1−/−) human gastric epithelial line GES-1 was constructed by CRISPR/CAS9 genome editing system. Results The gastric tumor incidence was higher in the SULT2B1−/− mice than in the wild-type (WT) mice. In gastric epithelial cells, adenovirus-mediated SULT2B1b overexpression reduced the levels of oxysterols, such as 24(R/S),25-epoxycholesterol (24(R/S),25-EC) and 27-hydroxycholesterol (27HC). This condition also increased PI3K/AKT signaling to promote gastric epithelial cell proliferation, epithelization, and epithelial development. However, SULT2B1 deletion or SULT2B1 knockdown suppressed PI3K/AKT signaling, epithelial cell epithelization, and wound healing and induced gastric epithelial cell malignant transition upon 3-MCA induction. Conclusions The abundant SULT2B1 expression in normal gastric epithelium might maintain epithelial function via the PI3K/AKT signaling pathway and suppress gastric carcinogenesis induced by a carcinogenic agent.

Abstract
Background Colorectal cancer (CRC) is a leading cause of cancer-related death worldwide. P21-activated kinase 4 (PAK4) and miR-9-5p have emerged as attractive therapeutic targets in several tumor types, but in CRC, the regulation of their biological function and their target association remain unclear. Methods The expression of PAK4 in CRC tissues was determined using quantitative real-time PCR and immunohistochemistry analyses. The targeted regulation between miR-9-5p and PAK4 was predicted and confirmed with bioinformatics analysis and the dual-luciferase reporter assay. Functional experiments, including the MTT assay and flow cytometry, were performed to investigate the impact of PAK4 knockdown and miR-9-5p overexpression on cell proliferation and apoptosis in CRC cells. Results We found that the expression of PAK4 was upregulated in CRC tissues. PAK4 knockdown significantly suppressed cell proliferation and promoted apoptosis in cells of the CRC cell lines HCT116 and SW1116. We also found that miR-9-5p directly targeted the 3′-UTR of PAK4 mRNA and negatively regulated its expression. The degree of downregulation of miR-9-5p inversely correlated with PAK4 expression. Intriguingly, enforced expression of miR-9-5p suppressed cell proliferation and promoted apoptosis. This could be partially reversed by PAK4 overexpression. Conclusion These results suggest that miR-9-5p targeting of PAK4 could have therapeutic potential for CRC treatment.

Abstract
Homoharringtonine (HHT) and imatinib have a synergistic effect in the clinical treatment of chronic myeloid leukemia (CML). The purpose of the present study was to explore the underlying mechanisms by which HHT enhanced imatinib sensitivity. K562 CML cells were treated with HHT and imatinib separately or in combination. Cell viability was detected by Cell Counting Kit-8 assay; apoptotic rates and protein expression levels of phosphorylated-tyrosine (p-Tyr) and p-CRK like proto-oncogene, adaptor protein (p-Crkl) were analyzed by flow cytometry; zinc-finger protein, X-linked (ZFX) overexpression plasmid was transfected to cells using electroporation; western blotting was used to detect the protein expression levels of PI3K, AKT, p-AKT and ZFX; and reverse transcription-quantitative PCR was used to measure ZFX mRNA expression levels. The results demonstrated that HHT and imatinib co-treatment had significant effects of proliferation inhibition and apoptosis induction on K562 CML cells compared with imatinib alone. Co-treatment also significantly downregulated the expression levels of p-Tyr, p-Crkl, PI3K and p-Akt compared with imatinib or HHT treatment. In addition, HHT downregulated ZFX mRNA and protein expression. ZFX overexpression reversed cell sensitivity to imatinib and HHT and also reduced the HHT-induced imatinib sensitization by increasing p-Akt expression. In conclusion, HHT may enhance the effect of imatinib on CML cells by downregulating ZFX.

Abstract
Background: Gastric cancer (GC) is one of the most lethal cancers worldwide with a high risk for recurrence and metastasis. Therefore, further understanding of the metastatic mechanism and the development of treatment strategies are required. Although increasing evidence suggests that SWI/SNF Related, Matrix Associated, Actin Dependent Regulator of Chromatin, Subfamily E, Member 1 (SMARCE1) promotes cancer metastasis, its role in GC remains unclear. Materials and methods: GC samples (n=122) were used to investigate the association between SMARCE1 expression, patient clinicopathological features, and prognosis. The expression of SMARCE1 in GC tissues was measured using real-time polymerase chain reaction, western blotting, and immunohistochemistry. MGC-803 and AGS cells were transfected with lentivirus to upregulate or downregulate SMARCE1 expression. The roles of SMARCE1 in GC cell proliferation, migration, and invasion were determined using Cell Counting Kit-8 assay, colony formation assay, wound healing, transwell migration, and invasion assay. Nude mice models were established to observe tumorigenesis. The specific mitogen-activated protein kinase (MAPK) inhibitor U0126 was utilized to verify the involved pathway. Results: SMARCE1 was highly expressed in GC tissues and cell lines. High expression of SMARCE1 was correlated with the malignant clinicopathological characteristics of GC patients, including tumor size, depth of invasion, degree of differentiation, lymph node involvement, and TNM stage (all P<0.05). Kaplan–Meier survival analysis revealed that high SMARCE1 expression predicted poor prognosis in GC patients (P<0.01). Moreover, SMARCE1 was an independent risk factor of poor prognosis (P<0.01). Functional study revealed that overexpression of SMARCE1 markedly promoted the proliferation, migration, and invasion of GC cells in vitro and tumorigenesis in vivo. Furthermore, SMARCE1 activated the MAPK/ERK signaling pathway. U0126 significantly inhibited the SMARCE1-induced proliferation and mobility of GC cells. Conclusion: SMARCE1 promoted growth and metastasis of GC, indicating its potential usefulness as a prognostic biomarker and target for therapeutic intervention against this disease.

Abstract
BACKGROUND Calbindin 1 (CALB1), a constituent Ca2+-binding protein, has been reported to prevent apoptotic death in tumor cells. However, the microRNA-mediated regulatory mechanism of CALB1 expression in nonsmall cell lung cancer (NSCLC) has not been reported so far. METHODS AND RESULTS In this study, CALB1 was found to be overexpressed in NSCLC tissues through the immunohistochemistry assay. Higher CALB1 expression levels were significantly associated with the tumor-node-metastasis (TNM) stage. Moreover, higher expression of CALB1 predicts poor survival in NSCLC patients using the Kaplan-Meier plotter online analysis. In addition, miR-454-3p was predicted to target CALB1 using a software algorithm, validated by the luciferase assay, and analyzed by quantitative polymerase chain reaction and Western blot. The authors further found that miR-454-3p was downregulated in NSCLC tissues and cell lines. Downregulation of CALB1 or upregulation of miR-454-3p significantly suppressed NSCLC cell proliferation and induced cell apoptosis as shown by CCK-8 and flow cytometry analysis, respectively. CONCLUSIONS Our results suggest that CALB1 is a direct target of miR-454-3p and downregulation of CALB1 by miR-454-3p suppressed NSCLC cell functions, which may shed light on its potential application in NSCLC therapy.

Abstract
Studies of long non-coding RNAs (lncRNAs) have been prevalent in the field of non-coding RNA regulation in recent years. LncRNAs exert crucial effects on malignant cell processes in the gastrointestinal system, including proliferation. Aberrant lncRNA expression, through both oncogenes and tumor suppressor genes, is instrumental to tumor cell proliferation. Here, we summarize the different molecular mechanisms and relevant signaling pathways through which multifarious lncRNAs regulate cell proliferation and we show that lncRNAs are potential biomarkers for gastrointestinal cancers.

Abstract
Surgical results for intrahepatic cholangiocarcinoma (ICC) remain unsatisfactory due to the high rate of recurrence. Here, we investigated that the expression and roles of tripartite motif‐containing protein 44 (TRIM44) in human ICCs. Firstly, TRIM44 expression was analyzed in several kinds of cancers by referring to public Oncomine database, and the expressions of TRIM44 mRNA and protein were tested in ICC and corresponding paratumorous tissues. Secondly, functions and mechanisms of TRIM44 in ICC cells were further evaluated by TRIM44 interference and cDNA transfection. Finally, the prognostic role of TRIM44 was assessed by Kaplan–Meier and Cox regression. We found that TRIM44 expression was upregulated in ICC tissues compared with corresponding paratumorous tissues, which were consistent with the results from the public cancer database. Knockdown of TRIM44 repressed the invasion and migration of ICC cells, while increased the ICC cell apoptosis. Additionally, high level of TRIM44 was shown to induce ICC cell epithelial to mesenchymal transition (EMT). Mechanistically, a high level of TRIM44 was found to activate MAPK signaling, and a MEK inhibitor, AZD6244, reversed cell EMT and apoptosis endowed by TRIM44 overexpression. Clinically, TRIM44 expression was positively associated with large tumor size (P = 0.035), lymphatic metastasis (P = 0.008) and poor tumor differentiation (P = 0.036). Importantly, patients in TRIM44high group had shorter overall survival and higher cumulative rate of recurrence than patients in TRIM44low group. Our results suggest elevated TRIM44 promotes ICC development by inducing cell EMT and apoptosis resistance, and TRIM44 is a valuable prognostic biomarker and promising therapeutic target of ICC.

Abstract
Gallbladder cancer (GBC), the most common malignancy of the bile duct, is highly aggressive and has an extremely poor prognosis, which is a result of early metastasis. As it is regulated being at multiple levels, the metastatic cascade in GBC is complex. Recent evidence suggests that microRNAs (miRNAs) are involved in cancer metastasis and are promising therapeutic targets. In this study, miR-101 was significantly downregulated in tumor tissues, particularly in metastatic tissues. In GBC patients, low miR-101 expression was correlated with tumor size, tumor invasion, lymph node metastasis, TNM stage, and poor survival. Moreover, miR-101 was an independent prognostic marker for GBC. Additionally, miR-101 inhibited GBC cell proliferation, migration, invasion, and TGF-β-induced epithelial-mesenchymal transition (EMT) in vitro and in vivo. Mechanistically, the gene encoding the zinc finger protein X-linked (ZFX) was identified as a direct target of miR-101. More importantly, miR-101 significantly reduced activation of the MAPK/Erk and Smad signaling pathways, resulting in inhibition of TGF-β-mediated induction of EMT. Altogether, our findings demonstrate a novel mechanism by which miR-101 attenuates the EMT and metastasis in GBC cells and suggest that miR-101 can serve as a potential biomarker and therapeutic target for GBC management.

High expression of Zinc-finger protein X-linked promotes tumor growth and predicts a poor outcome for stage II/III colorectal cancer patients. Oncotarget 2017; 7:19680-92.

Abstract
Zinc-finger protein X-linked (ZFX) was recently identified as a novel oncoprotein in several human malignancies. In this study, we examined the correlation between ZFX expression and the clinical characteristics of stage II/III CRC patients, as well as the molecular mechanism by which ZFX apparently contributes to CRC tumor progression. Using immunohistochemistry, we detected expression of ZFX in CRC tissues collected from stage II/III patients and determined that its expression correlated with tumor differentiation and stage. Survival analysis indicated that patients with high ZFX expression had poorer overall and disease-free survival. ZFX knockdown in SW620 and SW480 CRC cells significantly inhibited cell proliferation and colony formation, enhanced apoptosis and induced cell cycle arrest. It also enhanced the sensitivity of CRC cells to 5-Fu. In a xenograft model, ZFX knockdown suppressed in vivo CRC tumor growth. Microarray analysis revealed the primary target of ZFX to be DUSP5. Whereas ZFX knockdown increased DUSP5 expression, DUSP5 knockdown rescued ZFX-mediated cell proliferation in ZFX knockdown cells. These findings demonstrate that ZFX promotes CRC progression by suppressing DUSP5 expression and suggest that ZFX is a novel prognostic biomarker and potentially useful therapeutic target in stage II/III CRC patients.

Abstract
The divalent cation zinc is an integral requirement for optimal cellular processes, whereby it contributes to the function of over 300 enzymes, regulates intracellular signal transduction, and contributes to efficient synaptic transmission in the central nervous system. Given the critical role of zinc in a breadth of cellular processes, its cellular distribution and local tissue level concentrations remain tightly regulated via a series of proteins, primarily including zinc transporter and zinc import proteins. A loss of function of these regulatory pathways, or dietary alterations that result in a change in zinc homeostasis in the brain, can all lead to a myriad of pathological conditions with both acute and chronic effects on function. This review aims to highlight the role of zinc signaling in the central nervous system, where it may precipitate or potentiate diverse issues such as age-related cognitive decline, depression, Alzheimer's disease or negative outcomes following brain injury.

Abstract
Tumor-associated fibroblasts (TAFs) are often essential for solid tumor growth. However, few genetic or epigenetic alterations have been found in TAFs during the progression of solid tumors. Employing a tumor-stromal cell co-injection model, we adapted here retroviral-insertional mutagenesis to stromal cells to identify novel tumor-associated genes in TAFs. We successfully identified 20 gene candidates that might modulate tumor growth if altered in TAFs at genomic level. To validate our finding, the function of one of the candidate genes, tubulin tyrosine ligase (Ttl), was further studied in TAFs from fibrosarcoma, colon, breast and hepatocarcinoma. We demonstrated that down-regulated TTL expression in TAFs indeed promoted tumor growth in mice. Interestingly, decreased expression of TTL in tumor stromal cells also correlated with poor outcome in human colon carcinoma. Thus, the co-injection model of tumor cells with retrovirus-modified fibroblasts proved a valid method to identify tumor-modulating genes in TAFs, allowing for a deeper insight into the role of the stroma for tumor development.

Abstract
Zinc finger protein X-linked (ZFX) is frequently upregulated in multiple human malignancies and also plays a critical role in the maintenance of self-renewal in embryonic stem cells. However, the role of ZFX in liver cancer stem cells (CSCs) remains obscure. We observed that the elevated expression of both ZFX and epithelial cell adhesion molecule (EpCAM) was associated with aggressive clinicopathological features and indicated poor prognosis in patients with hepatocellular carcinoma (HCC). ZFX was commonly enriched in liver EpCAM+ CSCs. Knockdown of ZFX decreased the proportion of EpCAM+ CSCs in HCC cells and suppressed their expression of stemness-related genes, self-renewal capacity, chemoresistance, metastatic potential, and tumorigenicity. Conversely, upregulation of ZFX in CSCs rescued these inhibitory effects and enhanced stem-like properties. Mechanistically, depletion of ZFX reduced nuclear translocation and transactivation of β-catenin, thereby inhibiting the self-renewal capacity of EpCAM+ CSCs. Moreover, knockdown of β-catenin attenuated the self-renewal of EpCAM+ HCC cells stably expressing ZFX, further indicating that β-catenin is required for ZFX-mediated expansion and maintenance of EpCAM+ CSCs. Taken together, our findings indicate that ZFX activates and maintains EpCAM+ liver CSCs by promoting nuclear translocation and transactivation of β-catenin. Furthermore, combination of ZFX and EpCAM may serve as a significant indicator for prognosis of patients with HCC.

Abstract
Zinc finger protein X-linked (ZFX) is a key regulator of both embryonic stem cells (ESCs) and hematopoietic stem cells (HSCs), which is required for both Notch intracellular domain (NotchIC)-induced acute T-cell leukemia and MLL-AF9-induced myeloid leukemia in mouse models. However, the role of ZFX and its underlying mechanism in human leukemic cells remain unclear yet, though accumulating data have demonstrated that ZFX is aberrantly expressed in various human tumors and plays an important role. Herein, we found that ZFX was aberrantly expressed in various human leukemic cell lines and primary cells from leukemia patients compared with control cells. The silence of ZFX led to the growth suppression through either the deregulated cell cycle or the induction of apoptosis in various cells including K562, Jurkat, Namalwa, and THP-1 cells. The gene expression analysis revealed that UDP-Gal:βGlcNAc β 1,4-galactosyltransferase, polypeptide 1 (B4GALT1) was significantly down-regulated upon ZFX silencing, which is implicated in the response of K562 cells to the treatment of imatinib mesylate (IM). In addition, lectin blot assay showed that the galactosylation of glycoproteins in K562 cells was suppressed upon ZFX silencing. Interestingly, overexpression of B4GALT1 restored the growth and conferred drug resistance to ZFX-silenced cells. Taken together, we have demonstrated that ZFX is aberrantly expressed in multiple human leukemic cells and it modulates the growth and drug response of leukemic cells partially via B4GALT1, which suggests that ZFX is a new regulator of leukemic cells and warrants intensive investigations on this 'stemness' regulator in these deadly diseases.

Abstract
Zinc finger proteins are the largest transcription factor family in human genome. The diverse combinations and functions of zinc finger motifs make zinc finger proteins versatile in biological processes, including development, differentiation, metabolism and autophagy. Over the last few decades, increasing evidence reveals the potential roles of zinc finger proteins in cancer progression. However, the underlying mechanisms of zinc finger proteins in cancer progression vary in different cancer types and even in the same cancer type under different types of stress. Here, we discuss general mechanisms of zinc finger proteins in transcription regulation and summarize recent studies on zinc finger proteins in cancer progression. In this review, we also emphasize the importance of further investigations in elucidating the underlying mechanisms of zinc finger proteins in cancer progression.

Abstract
Zinc (Zn2+) is an essential metal in the brain, having critical roles in many proteins and cellular pathways, including synaptic plasticity and the normal functioning of long-term potentiation, the in vitro correlate of learning and memory. Importantly, several neurodegenerative diseases, such as Parkinson's disease and Alzheimer's disease, show alterations in Zn2+ metabolism that may be involved in the pathogenesis of these disorders. Therefore, the modulation of Zn2+ levels and/or distribution may prove an important target for the treatment of neurodegenerative diseases. This review aims to evaluate the current efforts directed at therapeutic Zn2+ modulation as it relates to disease-associated cognitive decline.

Abstract
Background This study was designed to assay the expression of zinc finger protein X-linked (ZFX) in renal cell carcinoma (RCC) tissues and evaluate the correlation between ZFX expression and prognosis of RCC patients. Material/Methods The expressions of ZFX mRNA in 53 RCC tissues and 51 normal tissues were determined by quantitative real-time polymerase chain reaction (qRT-PCR). Immunohistochemistry (IHC) technology was used to measure the expression of ZFX protein. Then chi-square test was conducted to verify the association between ZFX expression and clinical parameters. Next, we explored the overall survival rate of RCC patients with Kaplan-Meier analysis. Finally, the correlation between ZFX expression and the prognosis of RCC patients was evaluated by Cox regression analysis. Results The qRT-PCR result showed that the ZFX was significantly up-regulated in RCC tissues. As for the IHC consequence, the positive rate of ZFX expression in RCC specimens was 79.2%, while that in the normal control tissues was only 17.6%. Chi-square test showed that ZFX expression shared no close relationship with age, sex, or smoking (P>0.05), but was tightly associated with TNM stage, tumor size, and lymph node metastasis (P<0.05). Kaplan-Meier analysis showed that patients with ZFX positive expression had higher mortality than those with negative expression (P<0.05). Cox regression analysis revealed that ZFX expression had tight correlation with prognosis of RCC patients (HR=4.997, P=0.045, 95%CI=1.033–24.180). Conclusions Our findings show that ZFX could be considered as a predictor for prognosis of RCC patients.

Abstract
Background: The zinc finger transcription factor zinc finger protein, X-linked (ZFX) acts as an important director of self-renewal in several stem cell types. Moreover, ZFX expression abnormally increases in various cancers and relates to tumor grade. We performed this study, to examine its role in the pathogenesis of astrocytoma and meningioma. Materials and Methods: We used real-time reverse transcription polymerase chain reaction method for evaluation of ZFX expression in 25 astrocytoma tumoral tissue and 25 meningioma tumoral tissues with different WHO grades. Furthermore, the association of gene expression with various clinic-pathological characteristics was examined. Results: We found that there is a significant association between gene expression and different tumor grades, the presence or absence of invasion, forming and nonforming of glomeruloid vessels, the age over or under 50 and the presence or absence of calcification in astrocytomas. This is the first report that shows that ZFX was directly correlated with the central features of the neoplastic phenotype, including the growth of cancer cells, angiogenesis, and invasion. Conclusion: Regarding all the above-mentioned studies, it is highly plausible that silencing the expression of ZFX gene in gliomas has a major role in the therapeutic interventions of the disease in future.

Abstract
The Zinc finger X-chromosomal protein (ZFX), a novel member of the Krueppel C2H2-type zinc finger protein family, has been implicated in multiple human cancers. However, the clinical significance of ZFX expression in gallbladder cancer (GBC) remains largely unknown. In this study, we focused on the clinical significance, biological function and mechanism of ZFX in GBC, and found that ZFX protein overexpression was frequently detected in GBC tissues. The expression of ZFX was significantly correlated with histological grade, perineural invasion, and margin status and lead to a significantly poorer prognosis in GBC patients(P <0.001). Furthermore, knockdown of ZFX result in significant inhibition of proliferation, migration, invasion and cause cell cycle arrest in GBC-SD cells, while over-expression of ZFX in NOZ shows the opposite results. Activation of PI3K/AKT pathway maybe the potential mechanism behind these effects. In conclusion, ZFX may serve as a oncogene and could be used as a potential prognostic marker and genetic treatment target for GBC patients.

Abstract
Chronic inflammation contributes to tumor development through the induction of oncogenic mutations, genomic instability, early tumor promotion, and enhanced angiogenesis. Here, we report that IL-1 receptor 1 (IL-1R1) was expressed in 40 of 41 human tongue squamous cell carcinomas (TSCC). IL-1β up-regulated the expression of CXCR4, a CXC chemokine receptor that mediates cancer growth and metastasis, at both mRNA and protein levels in Tca8113 TSCC cells. IL-1β treatment of Tca8113 cells promoted migration in response to CXCR4 ligand stromal-derived factor α (SDF-1α). The inhibition of IL-1R1 by its antagonist IL-1Ra or RNA interference significantly reversed the up-regulation of CXCR4 induced by IL-1β. IL-1R1 activation also up-regulated the expression of IL-1β itself, suggesting a positive feedback regulation of CXCR4 expression. Furthermore, IL-1β induced the activation of Notch, which was originally considered a stem cell regulator. Pharmacological inhibition of Notch signaling reversed the up-regulation of CXCR4 induced by IL-1β, suggesting that Notch signaling may be involved in the growth and metastasis of cancers via up-regulation of CXCR4. In addition, IL-1β induced the activation of extracellular signal regulated kinase (ERK) and ERK inhibition decreased the up-regulation of CXCR4 induced by IL-1β, suggesting the involvement of ERK signaling in cancer metastasis. Taken together these data suggest that IL-1β and IL-1R1 promote cancer growth and metastasis by up-regulating CXCR4 expression and that CXCR4 may be a link between inflammation and cancer.

Abstract
Zinc finger protein X-linked (ZFX) is a zinc finger transcription factor and plays a significant role in the self-renewal ability of embryonic stem cells and various cancers. However, its expression and function in colorectal cancer (CRC) remain unclear. In the present study, we evaluated the expression of ZFX in CRC using quantitative polymerase chain reaction (qPCR), western blot analysis and immunohistochemistry (IHC), and further explored its potential functions in CRC cell lines using cell counting kit-8 and Transwell invasion assays. qPCR and western blot analysis revealed that ZFX was significantly upregulated in CRC tissues; IHC further confirmed this finding, revealing that higher expression of ZFX was significantly associated with larger tumor size (P=0.01), higher pathological stage (P=0.02), depth of invasion (P=0.047), lymph node invasion (P=0.02) and higher American Joint Committee on Cancer (AJCC) stage (P=0.04). CRC patients with higher ZFX expression also exhibited significantly shorter survival times (P=0.019). Moreover, knockdown of ZFX significantly suppressed proliferation and invasion in CRC cell lines HCT116 and LoVo. These results suggest that ZFX plays a notable role in CRC tumorigenicity and may serve as a novel marker and therapeutic target for CRC.

Abstract
The impact of cellular oxidative stress in promoting the epithelial-mesenchymal transition (EMT) has been noticed. Our previous study shows that SENP3, a redox-sensitive SUMO2/3-specific protease, accumulates in a variety of cancers, but whether SENP3 and SUMOylation involve in the regulation of EMT is unclear. The present study uncovers a novel role of SENP3 in promoting the EMT process in gastric cancer via regulating an EMT-inducing transcription factor, forkhead box C2 (FOXC2). We demonstrate that the expression of mesenchymal marker genes and cell migration ability are enhanced in SENP3-overexpressing gastric cancer cells and attenuated in SENP3-knockdown cells. A nude mouse model and a set of patient's specimens suggest the correlation between SENP3 and gastric cancer metastasis. Biochemical assays identify FOXC2 as a substrate of SENP3. Meanwhile N-cadherin is verified as a target gene of FOXC2, which is transcriptionally activated by a SUMO-less FOXC2. Additionally, reactive oxygen species-induced de-SUMOylation of FOXC2 can be blocked by silencing endogenous SENP3. In conclusion, SENP3, which is increased in gastric cancer cells, potentiates the transcriptional activity of FOXC2 through de-SUMOylation, in favor of the induction of specific mesenchymal gene expression in gastric cancer metastasis.

Abstract
Zinc finger protein, X-linked (ZFX) is a transcriptional factor involved in many physiological processes such as embryonic stem cell survival and self-renewal. Though ZFX dysfunctions have been identified in variant human diseases and especially in cancers, its pathological roles have not been fully addressed. Here, we explored the relationship between ZFX expression and squamous cell carcinoma (SCC) of the tongue. We found that ZFX expression was significantly higher in tongue SCC tumors as compared to tumor-adjacent normal tissues. Furthermore, ZFX knockdown impeded cell proliferation, impaired colony formation ability, and lead to cell cycle arrest while induced cell apoptosis in human tongue squamous cell carcinoma cell line Tca-8113. Our results provide evidence suggesting that ZFX overexpression is associated with the development of tongue SCC and ZFX knockdown is a potential treatment for tumor suppression.

[PMID: 25884313 PMCID: PMC4352287 DOI: 10.1186/s12885-015-1085-4] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2014] [Accepted: 02/12/2015] [Indexed: 12/18/2022] Open
Abstract
Background Structural maintenance of chromosomes 1A (SMC1A) is a member of the cohesion family of proteins that plays crucial roles in cell cycle control. Recent studies have concluded that SMC1A is involved in the pathogenesis of cancer. This study aims to evaluate the functional role of SMC1A in colorectal cancer (CRC) both in vitro and in vivo, and the underlying molecular mechanisms. Methods We firstly investigated the expression levels of SMC1A in 427 CRC specimens. Antigen expression was determined by immunohistochemical analysis of SMC1A on tissue microarrays. Stable SMC1A knockdown CRC cell lines were employed. The effects of SMC1A depletion on cell growth in vitro were examined by MTT, colony formation and flow cytometry assays. Tumor forming was evaluated by nude mice model in vivo. To detect the activation of intracellular signaling, pathscan intracellular signaling array and western blotting were performed. Results The expression of SMC1A was much stronger in CRC tumor tissues than in adenomas and normal colorectal tissues. High SMC1A expression, indicated as an independent poor prognostic predictor for patients with stage III and stage IV CRC, was correlated with overall survival (OS) (p = 0.008). Functional analysis indicated that SMC1A knockdown by small interfering RNA (siRNA) mediated the significant inhibition of cell proliferation; induced cell cycle arrest and apoptosis via the suppression of CDK4, PCNA and PARP; and blocked the activation of the Erk1/2 and Akt cascades in CRC cells. In addition, SMC1A depletion significantly decreased the growth of subcutaneously inoculated tumors in nude mice. Conclusions These results suggest that SMC1A plays an essential role in the development of CRC and may be a predictive factor in patients with CRC. The inhibition of SMC1A may serve as a promising therapeutic strategy for human CRC.

Abstract
Baicalein, a widely used Chinese herbal medicine, has multiple pharmacological activities. However, the precise mechanisms of the anti-proliferation and anti-metastatic effects of baicalein on gallbladder cancer (GBC) remain poorly understood. Therefore, the aim of this study was to assess the anti-proliferation and anti-metastatic effects of baicalein and the related mechanism(s) on GBC. In the present study, we found that treatment with baicalein induced a significant inhibitory effect on proliferation and promoted apoptosis in GBC-SD and SGC996 cells, two widely used gallbladder cancer cell lines. Additionally, treatment with baicalein inhibited the metastasis of GBC cells. Moreover, we demonstrated for the first time that baicalein inhibited GBC cell growth and metastasis via down-regulation of the expression level of Zinc finger protein X-linked (ZFX). In conclusion, our studies suggest that baicalein may be a potential phytochemical flavonoid for therapeutics of GBC and ZFX may serve as a molecular marker or predictive target for GBC.

Abstract
Orexins are hypothalamic peptides that regulate food intake, wakefulness, the reward system and energy metabolism. Recent studies have demonstrated the ability of orexins to promote a robust apoptosis and subsequent inhibition of cell growth in various types of cancer cells. The present study was conducted to investigate the effects of orexin A on the survival of human gastric cancer cells, SGC‑7901, and the possible mechanisms. SGC‑7901 cells were exposed to various concentrations of orexin A in vitro in the presence or absence of the orexin receptor 1 (OX1R) antagonist (SB334867), extracellular signal‑regulated kinases 1 and 2 (ERK1/2) antagonist (U0126) or a combination of the two antagonists. The amount of cell proliferation, viability and apoptosis, caspase‑8 and caspases‑9 activities, OX1R protein expression and ERK1/2 protein levels were determined. The expression of OX1R in SGC‑7901 cells was observed. Orexin A (10-10 to 10-6 M) stimulated SGC‑7901 cell proliferation and viability, reduced the pro‑apoptotic activity of caspase‑9 and protected the cells from apoptosis in a dose‑dependent manner. Additionally, ERK1/2 phosphorylation was stimulated by orexin A (10-10 to 10-6 M). However, the OX1R antagonist SB334867 (10-6 M), ERK1/2 antagonist U0126 (30 µM) or the combination of antagonists blocked the effects of orexin A to a certain extent. These results suggest that stimulation of OX1R induces the growth of SGC‑7901 gastric cancer cells through activation of ERK1/2 signaling pathway. These findings add a new dimension to the biological activities of orexin, which may have important implications in health and disease, in particular gastric cancer.

Abstract
Gastric cancer is the second most prominent cause of cancer mortality in the world. This study was designed to identify the possible use of si-RNA-mediated PDLIM5 gene silencing as a therapeutic tool for gastric cancer. Expression levels of PDLIM5 were detected in several gastric cancer cell lines using Western blot and qRT-PCR. We found PDLIM5 is highly expressed in all cultured gastric cancer cell lines. Small interfering RNA (si-RNA) was then employed to knock down PDLIM5 expression in MGC80-3 gastric cancer cells. Knockdown of PDLIM5 significantly inhibited cell proliferation and colony formation. Moreover, the absence of PDLIM5 in MGC80-3 cells led to S phase cell cycle arrest and apoptosis. This study highlights the critical role of PDLIM5 in gastric cancer cell growth and suggests that si-RNA-mediated silencing of PDLIM5 might serve as a potential therapeutic approach for the treatment of gastric cancer.

Abstract
The molecular abnormalities leading to sporadic parathyroid adenomas, a common type of human endocrine neoplasm, are heterogeneous and incompletely understood. Using whole exome and direct sequencing of parathyroid adenoma DNA samples, we identified recurrent somatic mutations in the ZFX gene. ZFX is a member of Krueppel C2H2 type zinc finger protein family, was initially described as a homolog of ZFY, and has been implicated as a transcription factor regulating embryonic stem cell renewal. The ZFX mutations we identified were strikingly specific, focused in each tumor on one encoded residue in a hotspot of two consecutive highly conserved arginine residues (R786/787; arginine to glutamine, threonine or leucine) in a zinc finger domain near the C-terminus of the protein. The intragenic specificity of these recurrently selected mutations, their confirmed expression within the tumors, the absence of loss of heterozygosity, and the absence of these mutations among over 4000 ZFX alleles in the dbSNP137 database, strongly suggest a novel role for ZFX as a human proto-oncogene. Further, these observations highlight the mutated zinc-finger domain as a new focal point for understanding ZFX's normal and tumorigenic functions, and for development of molecularly-targeted therapeutics.

Abstract
1,25-Dihydroxyvitamin D3 [1,25(OH)2D3] plays an anticancer role in multiple types of cancer and potentiates the cytotoxic effects of several common chemotherapeutic agents. The hypercalcemia caused by 1,25(OH)2D3 alone or resistance to cisplatin weaken the anticancer effects of vitamin D. Thus, in this study, we aimed to investigate the synergistic effects of 1,25(OH)2D3 and cisplatin on the apoptosis and cell cycle progression of gastric cancer cells. BGC-823 human gastric cancer cells were treated with 1,25(OH)2D3 or cisplatin alone, or a combination of both agents. Cell apoptosis was assessed by TUNEL assay and flow cytometry. The expression of the apoptosis-related proteins, poly(ADP-ribose) polymerase (PARP), Bax, Bcl-2, caspase-3 and caspase-8, was examined using immunoblot analysis. ERK and AKT phosphorylation were examined by immunoblot analysis. The cell cycle distribution was determined by propidium iodide staining and flow cytometric analysis. p21 and p27 protein expression was also examined using immunoblot analysis. Our results revealed that co-treatment with 1,25(OH)2D3 enhanced cisplatin-induced apoptosis and upregulated the expression of Bax, and promoted the cleavage of PARP and caspase-3. The phosphorylation levels of ERK and AKT were reduced following combined treatment with 1,25(OH)2D3 and cisplatin. The percentage of cells in the G0/G1 phase was greater in the cells treated with the combined treatment than in those treated with either 1,25(OH)2D3 or cisplatin alone. p21 and p27 expression was upregulated following co-treatment with both agents. The results of this study suggest that 1,25(OH)2D3 potentiates cisplatin-mediated cell growth inhibition and cell apoptosis, which involves the upregulation of Bax, a decrease in ERK and AKT phosphorylation levels, and increased p21 and p27 levels.
