Tang N, Liu X. USP18 promotes colon adenocarcinoma progression via targeting the ERK-MNK signaling pathway. J Gene Med 2024; 26:e3709.

Abstract
BACKGROUND Colorectal cancer is the third most common malignancy worldwide and is one of the leading causes of cancer-related mortality. Ubiquitin-specific peptidase 18 (USP18) protein has been reported to exert different tumor-related effects in distinct tumor types. Here, we initially investigated the expression and signaling pathways of USP18 in colon adenocarcinoma (COAD). METHODS A quantitative real-time PCR was conducted to evaluate the mRNA level of USP18 in cultured cells. Immunohistochemical staining was used to explore the protein expression of USP18 in clinical COAD samples. Specific knockdown was achieved by transient transfection of small interfering RNAs into SW480 and HT29 cells using Lipo3000. Cell conting kit-8 assay, transwell assay and matrigel-transwell assays were conducted to evaluate proliferation, migration and invasion capacities, respectively. Western blotting was performed to analyze downstream signaling pathways. A chi-squared test and univariate and multivariate analyses were used to evaluate the clinical data. Xenografts from mice model were assessed to validate the in vitro findings. RESULTS Higher USP18 level was identified in COAD tissues and was positively correlated with advanced tumor stage. High USP18 protein expression indicated poorer prognosis of COAD patients. Silencing USP18 suppressed COAD cell proliferation and invasion via destabilizing extracellular signal-regulated kinase (ERK) protein and suppressing ERK downstream pathways. Simultaneously silencing interferon-stimulated gene 15 (ISG15) with USP18 can partially rescue the tumor cell viability, indicating its involvement in USP18 signaling. The oncogenic effects of USP18 were also confirmed in mice models. CONCLUSIONS USP18 plays oncogenic effects in colon adenocarcinoma via ISG15-ERK pathways. High USP18 expression indicates poor clinical outcomes for colon adenocarcinoma patients.

Abstract
BACKGROUND Glioblastoma (GBM) is the most frequent glioma in adults. The prognosis of GBM is very poor and new prognostic biomarkers are in urgent need to better select high-risk patients and guide the individual treatments. METHODS In our study, we compared the expression of interleukin-17 receptor D (IL17RD) between GBMs and normal tissues from TCGA database, and detected IL17RD mRNA in 17 fresh GBM pairs with qPCR. With immunohistochemistry, we investigated the expression of IL17RD in 156 GBM tissues and further evaluated its clinical significance. The associations between IL17RD and clinicopathological factors were assessed by Chi-square test. The prognostic significance of IL17RD was evaluated by univariate analysis with Kaplan-Meier method, and by multivariate analysis with Cox-regression Hazard model. RESULTS The TPMs and mRNAs of IL17RD in GBM were substantially lower than those in normal brain tissues. The rates of low or high expression of IL17RD accounted for 41.67% and 58.33% respectively. IL17RD was significantly associated with higher survival rates of GBM. The 3-year overall survival rates of patients with low and high IL17RD were 7.2% and 19.5% respectively. In the Cox-regression model, the IL17RD expression was defined as an independent prognostic biomarker of GBM. Patients with high IL17RD expression had a more favorable outcome than those with low IL17RD. CONCLUSIONS High IL17RD expression was an independent prognostic indicator of GBM, suggesting a more favorable prognosis. Our results suggested that IL17RD detection may help find the high-risk patients which may receive more severe surveillance and more individual treatments.

Abstract
BACKGROUND Glioblastoma multiforme (GBM) is the most malignant glioma with highly aggressive behavior and the worst prognosis. Many efforts have been made to develop new drugs and improve the patient's survival, but the effects are not satisfactory. Here we aimed to evaluate the clinical significance and tumor-repressive function of Sprouty4 (SPRY4) in GBM. METHODS In our study, we detected the expression of SPRY4 in 109 GBM patients and 12 pairs of GBM tissues and the corresponding adjacent tissues. χ2 test was applied to analyze the association between SPRY4 expression and the clinicopathological factors. The prognostic significances were evaluated with univariate and multivariate analyses, which were carried out by the Kaplan-Meier method and the Cox-regression proportional hazards model, respectively. With in-vitro experiments, we investigated the tumor-suppressing function of SPRY4 in GBM invasion and investigated the underlying mechanism. RESULTS SPRY4 mRNAs in GBMs were significantly lower than those in adjacent brain tissues. We demonstrated that SPRY4 expression could predict the favorable prognosis of GBM, and SPRY4 was an independent favorable prognostic factor of GBM. SPRY4 repressed GBM invasion via inhibiting ERK phosphorylation; therefore, suppressing ETS-1-induced MMP9 expression. CONCLUSIONS SPRY4 was an independent favorable prognostic factor of GBM, and it could suppress GBM invasion by ERK-ETS-MMP9 axis. Our results indicated that SPRY4 may be a promising drug target of GBM and SPRY4 detection could stratify patients with low SPRY4 expression who may benefit from anti-FGFR therapy.

Abstract
Biliary tract cancers (BTCs), including cholangiocarcinoma and gallbladder carcinoma, originate from the biliary epithelium and have a poor prognosis. Surgery is the only choice for cure in the early stage of disease. However, most patients are diagnosed in the advanced stage and lose the chance for surgery. Early diagnosis could significantly improve the prognosis of patients. Bile has complex components and is in direct contact with biliary tract tumors. Bile components are closely related to the occurrence and development of biliary tract tumors and may be applied as biomarkers for BTCs. Meanwhile, arising evidence has confirmed the immunoregulatory role of bile components. In this review, we aim to summarize and discuss the relationship between bile components and biliary tract cancers and their ability as biomarkers for BTCs, highlighting the role of bile components in regulating immune response, and their promising application prospects.

Abstract
Background Immune system dysregulation plays a critical role in aortic valve calcification (AVC) and metabolic syndrome (MS) pathogenesis. The study aimed to identify pivotal diagnostic candidate genes for AVC patients with MS. Methods We obtained three AVC and one MS dataset from the gene expression omnibus (GEO) database. Identification of differentially expressed genes (DEGs) and module gene via Limma and weighted gene co-expression network analysis (WGCNA), functional enrichment analysis, protein–protein interaction (PPI) network construction, and machine learning algorithms (least absolute shrinkage and selection operator (LASSO) regression and random forest) were used to identify candidate immune-associated hub genes for diagnosing AVC with MS. To assess the diagnostic value, the nomogram and receiver operating characteristic (ROC) curve were developed. Finally, immune cell infiltration was created to investigate immune cell dysregulation in AVC. Results The merged AVC dataset included 587 DEGs, and 1,438 module genes were screened out in MS. MS DEGs were primarily enriched in immune regulation. The intersection of DEGs for AVC and module genes for MS was 50, which were mainly enriched in the immune system as well. Following the development of the PPI network, 26 node genes were filtered, and five candidate hub genes were chosen for nomogram building and diagnostic value evaluation after machine learning. The nomogram and all five candidate hub genes had high diagnostic values (area under the curve from 0.732 to 0.982). Various dysregulated immune cells were observed as well. Conclusion Five immune-associated candidate hub genes (BEX2, SPRY2, CXCL16, ITGAL, and MORF4L2) were identified, and the nomogram was constructed for AVC with MS diagnosis. Our study could provide potential peripheral blood diagnostic candidate genes for AVC in MS patients.

Abstract
BACKGROUND Disheveled-associated activator of morphogenesis (DAAM) family, including DAAM1 and DAAM2, is key regulators in Wnt signaling pathway. Although the oncogenic role of Wnt signaling pathway in colorectal cancer (CRC) was investigated in several lines, the expression and function of DAAM in CRC are still obscure. OBJECTIVE To investigate the expression and function of DAAM in CRC. METHODS DAAM1 and DAAM2 expression in high grade dysplasia (HGD), CRCs and corresponding adjacent tissues were detected with qRT-PCR and immunohistochemistry (IHC). The prognostic significance of DAAM1/2 were estimated with univariate and multivariate analyses. Moreover, the correlations between clinicopathological factors and DAAM were evaluated with the χ2 test. With experiments in vitro, we investigated the function of DAAM2 in CRC cell proliferation and invasion, and investigated the underlying mechanism of how DAAM2 facilitated CRC invasion. RESULTS DAAM2, instead of DAAM1, was substantially up-regulated in CRCs compared with paired adjacent normal tissues and HGDs. The ratio of high DAAM1 and DAAM2 expression accounted for 44.83% and 46.31%, respectively. High DAAM2, instead of DAAM1, was a risk factor indicating an unfavorable prognosis of CRC. In multivariate analysis, high DAAM2 was identified as an independent prognostic biomarker of CRC predicting poor prognosis. With experiments in vitro, DAAM2 promoted invasion of CRC cells via activating PAK1 and promoting the expression of MMP7, suggesting an essential role of DAAM2 in CRC invasion. CONCLUSIONS High expression of DAAM2, instead of DAAM1, indicated an unfavorable prognosis of CRC independently, which suggested that detecting DAAM2 can help define the high-risk patients. DAAM2 activated PAK1 and promoted MMP7 expression and facilitated the invasion of CRC cells, indicating that DAAM2 may be a potential drug target of CRC.

HMGA1-TRIP13 axis promotes stemness and epithelial mesenchymal transition of perihilar cholangiocarcinoma in a positive feedback loop dependent on c-Myc. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2021; 40:86.

Abstract
Background Cholangiocarcinoma is a highly malignant cancer with very dismal prognosis. Perihilar cholangiocarcinoma(pCCA) accounts for more than 50% of all cholangiocarcinoma and is well-characterized for its low rate of radical resection. Effects of radiotherapy and chemotherapy of pCCA are very limited. Methods Here we screened potential biomarkers of pCCA with transcriptome sequencing and evaluated the prognostic significance of HMGA1 in a large cohort pCCA consisting of 106 patients. With bioinformatics and in vitro/vivo experiments, we showed that HMGA1 induced tumor cell stemness and epithelial-mesenchymal-transition (EMT), and thus facilitated proliferation, migration and invasion by promoting TRIP13 transcription. Moreover, TRIP13 was also an unfavorable prognostic biomarker of pCCA, and double high expression of HMGA1/TRIP13 could predict prognosis more sensitively. TRIP13 promoted pCCA progression by suppressing FBXW7 transcription and stabilizing c-Myc. c-Myc in turn induced the transcription and expression of both HMGA1 and TRIP13, indicating that HMGA-TRIP13 axis facilitated pCCA stemness and EMT in a positive feedback pathway. Conclusions HMGA1 and TRIP13 were unfavorable prognostic biomarkers of pCCA. HMGA1 enhanced pCCA proliferation, migration, invasion, stemness and EMT, by inducing TRIP13 expression, suppressing FBXW7 expression and stabilizing c-Myc. Moreover, c-Myc can induce the transcription of HMGA1 and TRIP13, suggesting that HMGA-TRIP13 axis promoted EMT and stemness in a positive feedback pathway dependent on c-Myc.

Abstract
Background The small proline-rich protein 2B (SPRR2B) was firstly reported as a member of the cross-linked envelope protein in keratinocytes. The effect of SPRR2B in gastric adenocarcinoma (GC) remains unclear. This study initially explored the clinical significance of SPRR2B in GC patients as well as its role in tumor progression. Methods Immunohistochemistry was performed to characterize the expression of SPRR2B in GC tissues and adjacent tissues. The relationship between SPRR2B expression and clinicopathological features of GC patients was analyzed by Chi-square test. Kaplan-Meier method and Cox regression analyses were utilized to identify the prognostic factors of GC. Overexpression and knockdown assays were conducted to investigate possible signaling pathways downstream of SPRR2B. Flow cytometry assays were performed to evaluate cell cycle and apoptosis. Xenograft experiments were performed to validate tumor-related role of SPRR2B in vivo. Results Both mRNA and protein levels of SPRR2B in cancerous tissue were significantly higher than those in non-cancerous tissues. Meanwhile, SPRR2B expression was significantly associated with tumor size and tumor stage. Survival analysis revealed SPRR2B as one of the independent prognosis factors for overall survival of GC patients. Cellular and xenografts data implicated that silencing SPRR2B blocked the cell cycle of GC cells perhaps through MDM2-p53/p21-CDK1 pathway, while overexpressing SPRR2B exhibited opposite effects. Conclusion Our data suggest that SPRR2B may serve as a novel prognostic marker in GC, which functions at least partially by MDM2-p53/p21-CDK1 signaling pathway.

Abstract
Cholangiocarcinoma (CCA) is a highly aggressive malignancy with extremely poor prognoses. The oncogenic role and prognostic value of c-Myc in CCA is not well elucidated. WD repeat domain 5 (WDR5) is a critical regulatory factor directly interacting with c-Myc to regulate c-Myc recruitment at chromosomal locations, but the interaction of WDR5 and c-Myc in CCA was uncovered. In our study, we detected WDR5 and c-Myc expression in all CCA types, including intrahepatic (iCCA), perihilar (pCCA), and distal (dCCA) CCA, and evaluated their prognostic significance. Consequently, we demonstrated that WDR5 was significantly correlated with poor prognosis of CCA and that WDR5 and c-Myc co-expression was a more sensitive prognostic factor. With in vitro and in vivo experiments and bioinformatics, we showed that WDR5 interacted with the Myc box IIIb (MBIIIb) motif of c-Myc and facilitated Myc-induced HIF1A transcription, thereby promoting the epithelial-mesenchymal transition (EMT), invasion, and metastasis of CCA. Moreover, WDR5 enhanced hypoxia-inducible factor 1 subunit α (HIF-1α) accumulation by binding with histone deacetylase 2 (HDAC2) and increasing histone 3 lysine 4 acetylation (H3K4ac) deacetylation of the prolyl hydroxylase domain protein 2 (PHD2) promoter, resulting in the attenuation of chromatin opening and PHD2 expression, and eventually leading to HIF-1α stabilization and accumulation. In conclusion, WDR5 facilitated EMT and metastasis of CCA by increasing HIF-1α accumulation in a Myc-dependent pathway to promote HIF-1α transcription and a Myc-independent pathway to stabilize HIF-1α.

Abstract
Activating transcription factor 2(ATF2), a transcription factor belonging to the AP-1 family, plays an important role in inflammation. However, its biological functions and underlying molecular mechanisms in rheumatoid arthritis (RA) remain unclear. Western blot and immunohistochemistry were used to identify the expression of ATF2 and Sprouty2(SPRY2) in RA synovial tissues. SW982 cells were stimulated by TNF-α to establish an in vitro RA fibroblast-like synoviocyte (RA-FLS) model. Transwell and monolayer wound-healing were used to detect cell migration and invasion. RNA interference (si-ATF2) and adenovirus vector (Ad-SPRY2) methods were employed to manipulate ATF2 or SPRY2 expression in SW982 cells. The protein expression and phosphorylation levels in SW982 cells were evaluated by western blot. ATF2 expression and phosphorylation were upregulated in the RA synovial tissues. In RA-FLS model, ATF2 expression and phosphorylation were increased in a time-dependent manner. ATF2 knockdown inhibited the migration and invasion of RA-FLS model, reducing the inflammatory factors, which was consistent with the influence on cell behaviors caused by SPRY2 overexpression. Moreover, SPRY2 overexpression inhibited the TNF-α-induced phosphorylation of ERK and ATF2 in SW982 cells. The high expression and phosphorylation of ATF2 promoted migration and invasion of RA-FLSs. SPRY2 might inhibited the inflammatory responses of RA-FLSs via suppressing ERK-ATF2 pathway.

Abstract
Background Ovarian cancer is one of the most common malignant tumors in the female reproductive system with the highest mortality rate. Cul4B participates in the oncogenesis and progression of several malignant tumors. However, the role of Cul4B in ovarian cancer has not been studied. Results High expression of intratumor Cul4B was associated with poor patient survival. Cul4B expression was associated with FIGO stage and Cul4B was independent risk factor of ovarian cancer disease-free survival and overall survival. In vitro studies revealed that overexpression of Cul4B promoted tumor proliferation while knockdown of Cul4B significantly inhibited the proliferation capacity of ovarian cancer cells. Mechanistically, Cul4B was found to promotes cell entering S phase from G0/G1 phase by regulating the expression of CDK2 and CyclinD1. Cul4B regulates the expression of CDK2 and CyclinD1 by repressing miR-372. Conclusions The results revealed that high expression of Cul4B is associated with poor ovarian cancer prognosis and Cul4B may serve as a potential treating target for an adjuvant therapy.

[PMID: 32617870 DOI: 10.1007/s12094-020-02440-5] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Accepted: 06/19/2020] [Indexed: 01/15/2023]
Abstract
PURPOSE To explore FGF1 and miR-143-3p expression in hepatocellular carcinoma (HCC) cells and its related mechanisms. METHODS Eighty-two HCC patients treated at our hospital from January 2018 to January 2019 were enrolled as Group A, while further 80 healthy people undergoing physical examinations during the same time period were enrolled as Group B. HCC cells and normal human liver cells were purchased, with HepG2 and SMMC-7721 cells transfected with pcDNA3.1-FGF1, si-FGF1, NC, miR-143-3p-inhibitor and miR-143-3p-mimics. FGF1 and miR-143-3p expression was detected by qRT-PCR. The expression of N-cadherin, vimentin, Snail, Slug, E-cadherin and γ-catenin was detected by Western Blotting (WB). Cell proliferation was detected by MTT assay. Cell invasion was detected by Transwell. Cell apoptosis was detected by flow cytometry (FCM). RESULTS FGF1 was highly expressed but miR-143-3p was poorly expressed in HCC cells. Areas under the curves (AUCs) of the two indicators were > 0.8. The indicators were correlated with the age, gender, tumor invasion, degree of differentiation, tumor location and TNM staging of the patients. Silencing FGF1 and overexpressing miR-143-3p could promote cell apoptosis, inhibit cell growth, cell epithelial-mesenchymal transition (EMT) and the expression of N-cadherin, vimentin, Snail and Slug, and increase the expression of E-cadherin and γ-catenin. Dual luciferase reporter gene assay (DLRGA) confirmed that FGF1 and miR-143-3p had a targeted relationship. The rescue experiment showed that the proliferation, invasion and apoptosis of HepG2 and SMMC-7721 cells in the miR-143-3p-mimics+pcDNA3.1-FGF1 and miR-143-3p-inhibitor+Si-FGF1 groups were not different from those in the miR-NC group. CONCLUSION Inhibiting FGF1 can upregulate miR-143-3p-mediated Hedgehog signaling pathway, and affect cells' EMT, proliferation and invasion, so FGF1 is expected to become a potential therapeutic target for HCC.

Abstract
Most hepatocellular carcinoma (HCC) patients are diagnosed at an advanced stage; however, the effect of systemic therapy on advanced HCC remains undetermined. Therefore, new treatment targets must be identified. We analyzed Gene Expression Omnibus datasets from two HCC patient cohorts and found that NT5DC2 was associated with vascular invasion and poor survival. In two hepatoma cell lines, NT5DC2 overexpression promoted HCC cell proliferation and clone formation in vitro and promoted tumor growth in vivo. Coimmunoprecipitation assays and liquid chromatography with tandem mass spectrometry analysis revealed that NT5DC2 bound directly to epidermal growth factor receptor (EGFR). NT5DC2 upregulated EGFR expression by downregulating EGFR ubiquitination and preventing its degradation via the ubiquitin-proteasome pathway but did not upregulate its transcription. EGFR upregulation activated downstream signal transduction, which played a critical role in the protumor effects of NT5DC2. Erlotinib, a small-molecule inhibitor of EGFR, blocked the effect of NT5DC2 in promoting HCC cell proliferation. In a cohort of 79 patients who underwent curative resection for HCC, NT5DC2 expression in the tumors was associated with larger tumors and microvascular invasion. NT5DC2 expression was also independently associated with recurrence-free survival. The present study demonstrated for the first time that NT5DC2 promotes tumor cell proliferation in HCC and may serve as a potential molecular target for treating HCC. EGFR blockage could be used to treat selected patients with NT5DC2 upregulation.

Abstract
Tumor biomarkers are important in the early screening, diagnosis, therapeutic evaluation, recurrence and prognosis prediction of tumors. Primary liver cancer is one of the most common malignant tumors; it has high incidence and mortality rates and seriously endangers human health. The main pathological types of primary liver cancer include hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and combined HCC‑cholangiocarcinoma (cHCC‑CC). In the present review, a systematic outline of the current biomarkers of primary liver cancer is presented, from conventional blood biomarkers, histochemical biomarkers and potential biomarkers to resistance‑associated biomarkers. The important relationships are deeply elucidated between biomarkers and diagnosis, prognosis, clinicopathological features and resistance, as well as their clinical significance, in patients with the three main types of primary liver cancer. Moreover, a summary of several important biomarker signaling pathways is provided, which is helpful for studying the biological mechanism of liver cancer. The purpose of this review is to provide help for clinical or medical researchers in the early diagnosis, differential diagnosis, prognosis and treatment of HCC.

Abstract
BACKGROUND Krüppel-like factor 7 (KLF7), which belongs to the KLF family of zinc finger transcription factors, plays a critical role in regulating gene expression. It was reported that KLF7 overexpression was closely related to the progression of gastric cancer. However, the role of KLF7 in lung adenocarcinoma (LAC) has not been elucidated. The aim of our study is to investigate the expression pattern of KLF7 and explore whether the KLF7 expression is correlated with unfavorable clinical outcome of patients with LAC. MATERIALS AND METHODS The protein and mRNA levels of KLF7 were examined in LAC tissues by using immunohistochemistry staining and quantitative reverse transcription polymerase chain reaction, respectively. The prognostic role of KLF7 in patients with LAC was assessed using univariate and multivariate analyses. Clinical outcomes were evaluated by Kaplan-Meier analysis and logrank test. The effects of KLF7 on lung cancer cells were investigated through cellular experiments. RESULTS KLF7 expression was elevated in LAC tissues compared with adjacent normal tissues. High protein level of KLF7 was correlated with larger tumor size, positive lymph node metastasis, and advanced TNM stage. Moreover, patients with LAC with higher expression level of KLF7 had poorer overall survival, and KLF7 was identified as an unfavorable independent prognosis factor. Knockdown of KLF7 can suppress the proliferation and invasion abilities of cancer cells. CONCLUSIONS Our studies revealed that high KLF7 expression level was significantly associated with the poorer clinical outcomes of patients with LAC, indicating the potential role of KLF7 as a novel prognostic biomarker and therapeutic target.

Abstract
Hepatocellular carcinoma (HCC) is among the malignant tumors with highest mortality. The role of USP9X in the carcinogenesis of HCC has not yet been determined. In this study, USP9X was found significantly highly expressed in the intratumor tissues. Expression of intratumor USP9X was associated with tumor size and microvascular invasion while USP9X is independent risk factor of HCC disease-free survival and overall survival. In vitro studies revealed that knockdown of USP9X significantly inhibited the proliferation of HCC cells. Mechanically, USP9X promotes HCC cell proliferation by regulating the expression of beta-catenin. The results of the present study demonstrated that high expression of USP9X in intratumoral cells is associated with poor HCC prognosis, which may serve as a potential target for an adjuvant therapy.

Abstract
Intrahepatic cholangiocarcinoma (iCCA) is a highly malignant neoplasm arising from the intrahepatic bile ducts. As a scaffold protein of lipid rafts, flotillin-2 is upregulated in several types of cancer and promotes tumor progression and metastasis. To the best of our knowledge, the present study was the first to detect the upregulation of flotillin-2 in iCCA tissues compared with matched adjacent non-tumor tissues. In addition, immunohistochemistry was used to investigate the expression of flotillin-2 in a microarray consisting of 92 iCCA tissues. A total of 59 samples (64.1%) exhibited high flotillin-2 expression, which was significantly related to lymph node metastasis (P=0.029) and tumor-node-metastasis stage (P=0.016). Further in vitro study demonstrated that knockdown of flotillin-2 inhibited the invasive capability of iCCA cell lines, further supporting the participation of flotillin-2 in cancer invasion and metastasis. Moreover, Kaplan-Meier analysis showed patients with high flotillin-2 expression had worse overall survival outcomes. The multivariate Cox proportional hazards model further revealed that high flotillin-2 expression was an independent indicator (P=0.005) of poor prognosis for patients with iCCA. Collectively, the present study revealed that as a promoter of invasion and an independent marker of poor prognosis, flotillin-2 may serve as a potential target for the development of novel therapeutic agents for iCCA.

Abstract
Background Perihilar cholangiocarcinoma (PHCC) is the most common subtype of cholangiocarcinoma(CCA). We previously investigated the expression pattern of Sprouty(SPRY) in intrahepatic cholangiocarcinoma(ICC), but the expression and clinical significance of SPRY family members in PHCC are still unknown. Methods The expression of SPRY family members(SPRY1-4) was detected in different subtypes of CCA and corresponding adjacent tissues. SPRY4 expression in 142 cases of PHCC was detected by immunohistochemistry, and its clinical significance was evaluated using univariate and multivariate analyses. The functions of SPRY4 in the FGFR-induced proliferation and migration of PHCC cells were investigated through in vitro and in vivo experiments. We further investigated the effects and mechanisms of SPRY4 on FGFR-induced ERK phosphorylation and cell cycle distribution in the presence of FGFR and ERK inhibitors. Findings SPRY4 was the only SPRY family member associated with PHCC prognosis, and it was identified as an independent factor predicting favorable prognosis. In PHCC, SPRY4 expression was extensively associated with FGFR2, and its expression can be induced by ectopic FGFR2 activation. Through in vitro and in vivo experiments, we demonstrated that SPRY4 suppressed FGFR-induced proliferation and migration by inhibiting ERK phosphorylation. Moreover, SPRY4 knockdown was shown to decrease the percentage of cells in the G1 phase and promote the percentage of cells in the S and G2/M phases by increasing cyclin D1 expression, which also required FGFR-induced ERK phosphorylation. Interpretation High expression of SPRY4 was an independent biomarker of favorable prognosis in PHCC. SPRY4 expression can be induced by ectopic FGFR2 activation in PHCC. SPRY4 arrested the cell cycle at G1 phase and suppressed FGFR-induced proliferation and migration by inhibiting ERK phosphorylation, indicating that SPRY4 may be a potential therapeutic target in PHCC.

Abstract
Background Serine hydroxymethyltransferase (SHMT) is the enzyme that catalyzes the reversible conversion of serine to glycine and tetrahydrofolate-bound one-carbon unit. Upregulation of SHMT2 has been observed in a variety of cancers, but the expression profile and clinical value of SHMT2 in gastric cancer (GC) are still unknown. Material/Methods In this study, SHMT2 expression was assessed in 130 patients with GC by immunohistochemistry (IHC). mRNA of SHMT2 in GC tissues and normal gastric epithelium was compared with qRT-PCR results. The correlations between SHMT2 and the clinicopathologic factors were analyzed with the chi-square test. Univariate analysis with Kaplan-Meier method was used to estimate the correlations between survival rate and clinicopathologic factors, including SHMT2. The independent prognostic biomarkers were confirmed by multivariate analysis using the Cox-regression hazard model. The function of SHMT2 in progression of GC was assessed by in vitro experiments. Results The percentages of low and high expression of SHMT2 were 46.92% and 53.08%, respectively. SHMT2 mRNA in GC tissue was significantly higher than mRNA in the patient-paired adjacent tissues. In the clinical analysis, SHMT2 expression was notably associated with positive lymphatic invasion. High SHMT2 was also demonstrated to independently predict poor prognosis of GC. After silencing SHMT2, we proved that SHMT2 can promote proliferation and invasion of GC cells. Conclusions High SHMT2 promoted progression and was an independent prognostic biomarker of GC, suggesting that SHMT2 detection would be helpful for stratification of high-risk patients and thus directing personalized treatment.

Abstract
LncRNAs has been demonstrated to modulate neoplastic development by modulating downstream miRNAs and functional genes. In this study, we aimed to detect the interaction among lncRNA ZFAS1 miR‐296‐5p and USF1. We explored the proliferation, migration and invasion of cholangiocarcinoma. The differentially expressed ZFAS1 was discovered in both tissues and cell lines by qRT‐PCR. The targeting relationship between miR‐296‐5p and ZFAS1 or USF1 was validated by dual‐luciferase assay. The impact of ZFAS1 on CCA cell proliferation was observed by CCK‐8 assay. The protein expression of USF1 was determined by Western blot. The effects of ZFAS1, miR‐296‐5p and USF1 on tumour growth were further confirmed using xenograft model. LncRNA ZFAS1 expression was relatively up‐regulated in tumour tissues and cells while miR‐296‐5p was significantly down‐regulated. Knockdown of ZFAS1 significantly suppressed tumour proliferation, migration, invasion and USF1 expression. Overexpressed miR‐296‐5p suppressed cell proliferation and metastasis. Knockdown of USF1 inhibited cell proliferation and metastasis and xenograft tumour growth. In conclusion, ZFAS1 might promote cholangiocarcinoma proliferation and metastasis by modulating USF1 via miR‐296‐5p.

Abstract
Background Bladder cancer is the fourth most common cancer worldwide. Thyroid receptor-interacting protein 13 (TRIP13) is a member of the AAA+ ATPase family. The upregulation of TRIP13 has been shown to be involved in a few diseases, especially in cancers, but the expression and function of TRIP13 in bladder cancer is still elusive. Material/Methods In our study, the expression of TRIP13 was investigated with immunohistochemistry (IHC). The mRNAs of TRIP13 in bladder cancer and adjacent normal tissues were compared using quantitative real-time polymerase chain reaction (qRT-PCR) and IHC scores. The clinical value of TRIP13 was estimated by evaluating its correlation with other clinicopathological factors using the chi-square test. The prognostic significance of TRIP13 was evaluated using univariate and multivariate analyses. The effect of TRIP13 on proliferation and invasion was evaluated using function assays in vitro. Results In the 139 samples of bladder cancer tissues, the patients with low and high expression of TRIP13 accounted for 64.03% and 35.97%, respectively. Moreover, the mRNA expression of TRIP13 in bladder cancer was significantly higher than in normal tissues. High expression of TRIP13 was remarkably correlated with T stage, metastasis, and poor prognosis. In addition, TRIP13 was demonstrated to promote the proliferation, invasion, and epithelial-mesenchymal transition (EMT) of bladder cancer. Conclusions TRIP13 is correlated with poor prognosis of bladder cancer by promoting proliferation, invasion, and EMT, indicating that TRIP13 may be a promising drug target in bladder cancer.

Abstract
BACKGROUND As one of the most prevalent malignancies, hepatocellular carcinoma (HCC) ranks the third leading cause of cancer death worldwide. Due to the lack of biomarkers for early diagnosis, the clinical outcome of HCC remains unsatisfied with the current common therapeutic approaches, including surgery and chemotherapies. Thus, sensitive biomarkers and targeted therapies are in great need. AIMS In this study, we explored and verified whether CDHR5 (cadherin-related family member 5), a cadherin family protein, could serve as the potential biomarkers for HCC in the clinic. METHODS A retrospective study which contained 154 HCC patients was performed. Chi-square was utilized to analyze the relationship between CDHR5 expression and the clinicopathological features of HCC patients. The Kaplan-Meier method and Cox regression analyses were then used to evaluate the survival of HCC patients. In addition, cell proliferation assay and colony formation assay were performed to examine the effects of CDHR5 on the progression of HepG2 and Huh7 cells. RESULTS IHC and RT-qPCR revealed that CDHR5 was downregulated in HCC tissues compared with adjacent liver tissues. In addition, CDHR5 expression was significantly correlated with tumor numbers, tumor size, and TNM stage. CDHR5 expression was then shown to be an independent risk factor for survival of HCC patients by survival analysis. In vitro experiments showed that CDHR5 suppressed the proliferation capacity of HCC cells. CONCLUSIONS Taken together, our study not only identified CDHR5 as a novel prognostic biomarker in HCC but also provided evidence that CDHR5 can inhibit HCC cell proliferation.

Abstract
Background Serine hydroxymethyltransferase 2 (SHMT2) is a key enzyme in one-carbon cell metabolism, including in liver cancer. However, the associations between SHMT2 expression at the gene and protein level and prognosis in patients with hepatocellular carcinoma (HCC) remains unknown. This study aimed to investigate the expression levels of SHMT2 in tumor tissue samples from patients with HCC and clinical outcome and the effects of silencing the expression of the SHMT2 gene in HepG2 cells. Material/Methods Expression levels of SHMT2 were evaluated in 144 cases of HCC using immunohistochemistry and correlated with clinicopathological factors using the chi-squared (χ2) test. The prognostic significance of SHMT2 expression was analyzed by univariate analysis and multivariate analysis. Twenty pairs of HCC tissue and adjacent normal liver tissue were compared for SHMT2 expression levels using quantitative reverse transcription polymerase chain reaction (qRT-PCR). HepG2 cells underwent SHMT2 gene silencing and MTT and transwell assays investigated cell proliferation and migration. Western blot was used to detect the expression of markers of epithelial-mesenchymal transition (EMT). Results Expression levels of SHMT2 in HCC tissues were significantly correlated with tumor grade and hepatitis B virus (HBV) infection, and increased expression was an independent negative prognostic factor in patients with HCC (P=0.003). Increased expression of the SHMT2 gene promoted the proliferation and migration of the HepG2 HCC cell line. Conclusions Increased expression of SHMT2 was a negative prognostic biomarker in patients with HCC. Expression of the SHMT2 gene promoted the proliferation and migration of HepG2 HCC cells.

Abstract
Background Perihilar cholangiocarcinoma (PHCC) is the most common type of cholangiocarcinoma with the worst prognosis. Radical resection of PHCC is difficult; thus, few effective biomarkers or useful molecular profiles for PHCC have been reported in recent years. Therefore, in this study, we aimed to assess biomarkers for PHCC. Methods We screened potential biomarkers for PHCC using exome and transcriptome sequencing with PHCC tissues and paired normal tissues. Transcription factor 7 (TCF7) expression was evaluated using quantitative reverse transcription polymerase chain reaction, western blotting, and immunohistochemistry. The correlations between TCF7 and clinicopathological factors were analyzed with Chi-square test, and the prognostic significance of TCF7 was evaluated with univariate and multivariate analyses. The functions of TCF7 and its main effectors in PHCC cells were investigated in vitro and in vivo. Findings TCF7 expression was upregulated in PHCC and was an unfavorable prognostic biomarker. c-Myc was a main effector of TCF7 in PHCC cells and modulated TCF7-induced proliferation, invasion, and migration. FOS-like antigen 1 (FOSL1) was identified as a downstream target of TCF7 and was required in TCF7-induced PHCC proliferation. Triple-positive expression of TCF7, c-Myc, and FOSL1 predicted a much worse prognosis in patients with PHCC than TCF7 expression alone. Interpretation Postoperative detection of TCF7, c-Myc, and FOSL1 may be useful for stratifying patients with a high risk of unfavorable prognosis, and suppressing TCF7 or its downstream effectors may be a promising strategy for the treatment of PHCC.

Abstract
Background The WD repeat domain 5 (WDR5) is an essential component of methyltransferase complexes. The expression of WDR5 has been reported in several types of malignancy. This study aimed to investigate the expression of the WDR5 gene and protein in a human papillary carcinoma cell line in vitro, including the use WDR5 gene silencing, and the expression of the WDR5 protein in papillary thyroid carcinoma tissue, and clinicopathological characteristics including overall survival (OS). Material/Methods The role of WDR5 in proliferation and migration of the human papillary thyroid carcinoma cell line, KTC-1, was investigated using the cell counting kit-8 (CCK-8) assay and transwell assay after silencing WDR5 expression. Expression levels of WDR5 in 84 patients with papillary thyroid carcinoma were detected using immunohistochemistry. The correlation between WDR5 expression and clinicopathological features was analyzed using the chi-squared test. The prognostic role of WDR5 was evaluated by univariate analysis with the log-rank test, and by multivariate analysis with the Cox regression model. Results WDR5 expression promoted the proliferation and migration of the KTC-1 cells. In tumor tissue from patients with papillary thyroid carcinoma, low expression and high expression levels of WDR5 were found in 72.6% and 27.4%, respectively. Increased expression of WDR5 was significantly associated with lymphatic invasion and reduced survival rates. WDR5 expression was an independent negative prognostic biomarker. Conclusions Expression of WDR5 promoted cell proliferation and migration in vitro and was associated with reduced prognosis in patients with papillary thyroid carcinoma.

Abstract
The Ras/Raf/ERK pathway is one of the most frequently dysregulated signaling pathways in various cancers. In some such cancers, Ras and Raf are hotspots for mutations, which cause continuous activation of this pathway. However, in some other cancers, it is known that negative regulators of the Ras/Raf/ERK pathway are responsible for uncontrolled activation. The Sprouty/Spred family is broadly recognized as important negative regulators of the Ras/Raf/ERK pathway, and its expression is downregulated in many malignancies, leading to hyperactivation of the Ras/Raf/ERK pathway. After the discovery of this family, intensive research investigated the mechanism by which it suppresses the Ras/Raf/ERK pathway and its roles in developmental and pathophysiological processes. In this review, we discuss the complicated roles of the Sprouty/Spred family in tumor initiation, promotion, and progression and its future therapeutic potential.

Abstract
BACKGROUND Osteosarcoma (OS) patients with metastasis have very dismal prognoses, and lack effective target therapies. Overexpression of cytosolic phospholipase A2 (cPLA2) has been shown to promote progression in several types of cancers, but its functions in OS have not been investigated. MATERIALS AND METHODS In our study, the expression of cPLA2a was detected with immunohistochemistry in 102 cases of OS. The clinical significance of cPLA2a was evaluated by analyzing its correlation with clinicopathological factors. The prognostic significance of cPLA2a was estimated by univariate and multivariate analysis. The oncogenic functions of cPLA2a on cell proliferation and invasion were investigated by MTT assay and tranwell assay respectively. Western blotting was applied to detect the markers of epithelial-mesenchymal transition (EMT) after silencing cPLA2a expression or inhibiting its activity by a specific antagonist. RESULTS In our study, high expression of cPLA2a was significantly associated with metastasis and advanced Enneking stage. High cPLA2a expression was significantly associated with poor prognosis and it was an independent prognostic biomarker of OS. By silencing cPLA2a or inhibiting its activity by a specific antagonist, we demonstrated that cPLA2a promoted cell invasion of OS cells via inducing the EMT process. CONCLUSIONS High cPLA2a expression was an independent prognostic biomarker of OS, and cPLA2a could promote OS cell invasion via inducing the EMT process, indicating that cPLA2a was an independent prognostic biomarker and may be an effective drug target for OS.

Abstract
Fibroblast growth factor receptor 2 (FGFR2) was demonstrated to correlate to the progression and prognosis of intrahepatic cholangiocarcinoma (ICC) by numerous evidences. However, as a well‐recognized suppressor of FGFR2 signalling, the clinical significance of Sprouty (SPRY) family of ICC has not been investigated. In our study, the expressions of SPRY1‐4 in 20 pairs of fresh tumour tissues were detected with qPCR, and in 108 cases of paraffin‐embedded tissues with immunohistochemistry. The prognostic value of SPRY family in ICC was estimated with univariate analysis and multivariate analysis. As a result, SPRY2 was identified as an independent prognostic biomarker predicting favourable prognosis of ICC. High SPRY2 expression was correlated with good differentiation of ICC. With silencing SPRY2 expression, we demonstrated that SPRY2 could suppress FGFR2‐induced ERK phosphorylation, migration, invasion and epithelial‐mesenchymal transition (EMT) under FGF1 stimulation. By overexpressing SPRY2‐wide type or SPRY2‐Y55F, the tyrosine‐55 of SPRY2 was demonstrated to be essential in suppressing ERK phosphorylation, tumour invasion and EMT of ICC cells. In conclusion, SPRY2 was correlated with favourable prognosis of ICC via suppressing FGFR2‐induced ERK phosphorylation, invasion and EMT. The phosphorylation of SPRY2‐Y55 was required in this tumour‐suppressing function of SPRY2.
