Abstract
Hippo-Yes-associated protein 1 (YAP1) plays an important role in gastric cancer (GC) progression; however, its regulatory network remains unclear. In this study, we identified Copine III (CPNE3) was identified as a novel direct target gene regulated by the YAP1/TEADs transcription factor complex. The downregulation of CPNE3 inhibited proliferation and invasion, and increased the chemosensitivity of GC cells, whereas the overexpression of CPNE3 had the opposite biological effects. Mechanistically, CPNE3 binds to the YAP1 protein in the cytoplasm, inhibiting YAP1 ubiquitination and degradation mediated by the E3 ubiquitination ligase β-transducin repeat-containing protein (β-TRCP). Thereby activating the transcription of YAP1 downstream target genes, which creates a positive feedback cycle to facilitate GC progression. Immunohistochemical analysis demonstrated significant upregulation of CPNE3 in GC tissues. Survival and Cox regression analyses indicated that high CPNE3 expression was an independent prognostic marker for GC. This study elucidated the pivotal involvement of an aberrantly activated CPNE3/YAP1 positive feedback loop in the malignant progression of GC, thereby uncovering novel prognostic factors and therapeutic targets in GC.

Abstract
Background: Even with decades of intensive study, the signaling regulative network of the progression of Glioblastoma (GBM) remains unclear, a deeper understanding of the molecular crosstalk with pathways in GBM is needed to identify new potential targets for treatment. Copine-3 (CPNE3) was a member of a Ga2+ -dependent phospholipid-binding protein and was reported to play a role in multiple cancers. Methods: To investigate the expression of CPNE3 in GBM, we applied bioinformatic analysis and clinical samples validation. Then the functional validation of carried out in commercially available glioma cell lines and nude mice model. Also, the GSEA analysis was used to identify the relevant pathways. The role of activated pathway was further validated by pharmacology method. Results: We found that CPNE3 was significantly up-regulated in GBM when compared with adjacent normal tissues, and the overexpression of CPNE3 promoted cell proliferation and inhibiting cell apoptosis in vitro and in vivo. Also, the principal protein markers of PI3K/AKT pathway were found to be phosphorylated by CPNE3 over-expression, and pathway inhibitor, LY294002, alleviated the cell proliferation enhancement induced by CPNE3 over-expression. Conclusion: Our results showed that the expression of CPNE3 promotes cell proliferation by inhibiting cell apoptosis via activating PI3K/AKT pathway. Thereby enhancing the progression of GBM, which suggest that CPNE3 may play as a tumorigenesis gene may become a promising potential therapeutic target for human GBMs.

Abstract
Lung cancer is the leading cause of cancer-related deaths worldwide. Despite significant advances in cancer research and treatment, the overall prognosis of lung cancer patients remains poor. Therefore, the identification for novel therapeutic targets is critical for the diagnosis and treatment of lung cancer. CPNEs (copines) are a family of membrane-bound proteins that are highly conserved, soluble, ubiquitous, calcium dependent in a variety of eukaryotes. Emerging evidences have also indicated CPNE family members are involved in cancer development and progression as well. However, the expression patterns and clinical roles in cancer have not yet been well understood. In this review, we summarize recent advances concerning CPNE family members and provide insights into new potential mechanism involved in cancer development.

Abstract
Glioblastoma (GBM) is a deadly brain tumor with a bleak prognosis. In recent years, the copine III (CPNE3) protein was discovered to be associated to metastasis across various types of malignancies. Nevertheless, its function has not been well documented in glioma. This study characterizes CPNE3 expression in GBM along with its impact and underlying molecular mechanism with regards to cellular migration, invasion and proliferation. Immunohistochemistry was used to characterizes CPNE3 expression in the glioma tissues. Then, knockdown of CPNE3 expression was used to analyze the role of CPNE3 in GBM cell viability, migration, invasion. Western blot analysis was performed to measure the protein levels of FAK signaling pathway. We found that GBM tissues had higher CPNE3 expressions as compared to those in normal brain tissues. CPNE3 silencing in GBM cells impaired the migratory, invasive and proliferative abilities of GBM cells that can be attributed to inactivation of the FAK signaling pathway. Collectively, these findings highlight the role of CPNE3 as a new biomarker, offering deeper insights into its carcinogenic role in GBM.

Abstract
BACKGROUND CPNEs are significant biomarkers which can affect the progression and prognosis of various tumor diseases. However, the prognosis role of CPNEs in multiple myeloma (MM) is still unclear. OBJECTIVES To investigate the prognosis role of CPNEs in MM. METHODS Seven hundred and thirty-five samples from two independent data sets were involved to analyze the clinical and molecular characteristics, and prognosis role of the expression of CPNE1-9 in MM. RESULTS MM patients with higher expressions of CPNE5 and CPNE9 had longer event-free survival (EFS) and overall survival (OS) compared with CPNE5low and CPNE9low expression groups (EFS: P= 0.0054, 0.0065; OS: P= 0.015, 0.016, respectively). Multivariate regression analysis showed that CPNE5 was an independent favorable predictor for EFS and OS (EFS: P= 0.005; OS: P= 0.006), and CPNE9 was an independent positive indicator for EFS (P= 0.002). Moreover, the survival probability and the cumulative event of EFS and OS in CPNE5highCPNE9high group were significantly longer than other groups. CONCLUSIONS High expressions of CPNE5 and CPNE9 might be used as positive indicators for MM, and their combination was a better predictor for the survival of MM patients.

Abstract
Gastric cancer is one of the most common types of malignancy worldwide. Tac2-N (TC2N) has been reported to serve as either an oncogene or tumor suppressor in numerous different types of cancer; however, the role of TC2N in gastric cancer remains poorly understood. The present study aimed to investigate the role of TC2N in gastric cancer and reveal its regulatory mechanism. A Cell Counting Kit-8 assay was used to analyze the cell proliferation rate, while wound healing and Transwell Matrigel assays were performed to determine the cell migratory and invasive abilities, respectively. Cell cycle distribution was determined by flow cytometric analysis, and the expression levels of TC2N, P-glycoprotein (P-gp), cyclin D1, CDK4, cyclin E1, MMP2, MMP9 and N-Myc downstream regulated gene 1 were analyzed using reverse transcription-quantitative PCR or western blotting. Bioinformatics analysis revealed a high expression of TC2N in patients with gastric cancer. The experimental results revealed that TC2N expression levels were significantly unregulated in gastric cancer cell lines. The knockdown of TC2N in AGS cells significantly inhibited the cell proliferation rate and induced cell cycle arrest at the G0/G1 phase, while downregulating cyclin E1, cyclin D1 and CDK4 expression levels. The knockdown of TC2N also inhibited cell migration and invasion. Furthermore, the knockdown of TC2N improved the sensitivity of AGS cells to cisplatin, paclitaxel and 5-fluorouracil, and downregulated the protein expression levels of P-gp. By contrast, TC2N overexpression exerted the opposite effects in AGS cells. In conclusion, the findings of the present study indicated that the genetic knockdown of TC2N may inhibit cell proliferation, migration and invasion, while inducing cell cycle arrest in the G1/S phase and reversing the drug resistance of AGS cells, which may be partly through inhibiting P-gp expression levels. Thus, TC2N may serve as a novel diagnostic marker and therapeutic target for patients with gastric cancer.

Abstract
Cinobufotalin is a chemical compound extracted from the skin of dried bufo toads that may have curative potential for certain malignancies through different mechanisms; however, these mechanisms remain unexplored in breast cancer. The aim of the present study was to investigate the antitumor mechanism of cinobufotalin in breast cancer by using microarray data and in silico analysis. The microarray data set GSE85871, in which cinobufotalin exerted influences on the MCF‑7 breast cancer cells, was acquired from the Gene Expression Omnibus database, and the differentially expressed genes (DEGs) were analyzed. Subsequently, protein interaction analysis was conducted, which clarified the clinical significance of core genes, and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes were used to analyze cinobufotalin‑related pathways. The Connectivity Map (CMAP) database was used to select existing compounds that exhibited curative properties similar to those of cinobufotalin. A total of 1,237 DEGs were identified from breast cancer cells that were treated with cinobufotalin. Two core genes, SRC proto‑oncogene non‑receptor tyrosine kinase and cyclin‑dependent kinase inhibitor 2A, were identified as serving a vital role in the onset and development of breast cancer, and their expression levels were markedly reduced following cinobufotalin treatment as detected by the microarray of GSE85871. It also was revealed that the 'neuroactive ligand‑receptor interaction' and 'calcium signaling' pathways may be crucial for cinobufotalin to perform its functions in breast cancer. Conducting a matching search in CMAP, miconazole and cinobufotalin were indicated to possessed similar molecular mechanisms. In conclusion, cinobufotalin may serve as an effective compound for the treatment of a subtype of breast cancer that is triple positive for the presence of estrogen, progesterone and human epidermal growth factor receptor‑2 receptors, and its mechanism may be related to different pathways. In addition, cinobufotalin is likely to exert its antitumor influences in a similar way as miconazole in MCF‑7 cells.

Abstract
Despite advances in diagnosis and treatment, the survival of non-small cell lung cancer (NSCLC) patients is poor. Further understanding of the disease mechanism and treatment strategies is required. Copines are a family of calcium-dependent phospholipid-binding proteins that are evolutionally conserved in various eukaryotic organisms and protists. Copine 1, encoded by CPNE1, is a soluble membrane-binding protein, which includes two tandem C2 domains at the N-terminus and an A domain at the C-terminus. A previous study reported that Copine 1 binds with various intracellular proteins via its A domain and C omain. However, the role of CPNE1 in lung cancer remains unclear. In the presented study, CPNE1 expression level was demonstrated to be positively associated with the stage (P=0.002) and significantly associated with lymph node status (P=0.011) and distant metastasis (P=0.042). Furthermore, the function of CPNE1 in regulation of cell growth, migration and invasion was investigated, and it was demonstrated that knockdown of CPNE1 inhibits the cell cycle in NSCLC cells. Collectively, these data suggest that CPNE1 is an oncogene in NSCLC and serves an important role in tumorigenesis of NSCLC progression.

Abstract
Background The application of the oral targeted therapeutic agent sorafenib provides new hope for patients suffering from advanced stages of hepatocellular carcinoma (HCC), but the prognosis of such patients remains poor due to the rapid development of the multidrug resistance process in cancer pathogenesis. The present work evaluated whether copine-III, a novel cancer regulator encoded by the CPNE3 gene, would be a potential indicator of sorafenib resistance in HCC treatment. Materials and methods The endogenous expression of copine-III in clinical specimens was examined by quantitative polymerase chain reaction. Copine-III siRNA was transfected into HCC cells to downregulate copine-III expression. The effect of copine-III on sorafenib’s antitumor activation was identified by in vitro and in vivo experiments (MTT, Transwell, and flow cytometry as well as a nude mice model). Results High levels of copine-III in clinical specimens are related to poor prognosis of advanced HCC patients on sorafenib treatment. Infection of Ad-siCPNE3 significantly decreased the endogenous expression of copine-III and enhanced the susceptibility of MHCC97-H cells to sorafenib: the IC50 value decreased from 1.15±0.11 to 0.25±0.05 μmol/L. Moreover, silencing copine-III enhanced the effect of sorafenib on apoptosis, in vitro invasion/migration, and subcutaneous or intrahepatic growth of MHCC97-H cells in nude mice. Conclusion Copine-III is a novel potential indicator of prognosis for patients who received sorafenib for advanced HCC treatment.

Abstract
Background Despite advances in diagnosis and treatment, the survival of non-small cell lung cancer (NSCLC) patients remains poor. There is therefore a strong need to identify potential molecular targets for the treatment of NSCLC. In the present study, we investigated the function of CPNE1 in the regulation of cell growth, migration and invasion. Methods Quantitative real-time PCR (qRT-PCR) was used to detect the expression of CPNE1 and miR-335-5p. Western blot and immunohistochemical assays were used to investigate the levels of CPNE1 and other proteins. Flow cytometry was used to determine cell cycle stage and apoptosis. CCK-8 and clonogenic assays were used to investigate cell proliferation. Wound healing, migration and invasion assays were used to investigate the motility of cells. A lung carcinoma xenograft mouse model was used to investigate the in vivo effects of CPNE1 overexpression. Results We observed that knockdown of CPNE1 and increased expression of miR-335-5p inhibits cell proliferation and motility in NSCLC cells, and found that CPNE1 was a target of miR-335-5p. In addition, our data indicated that CPNE1 inhibition could improve the clinical effects of EGFR-tyrosine kinase inhibitors. Conclusions The present results indicate that CPNE1 may be a promising molecular target in the treatment of NSCLC.

Abstract
Background CPNE1 plays a vital role in regulating cell differentiation. The clinical and biological values of CPNE1 in prostate cancer are still unclear. The aim of this study was to investigate the clinicopathological value of CPNE1 and the association of CPNE1 with TRAF2 expression in patients with prostate cancer. Material/Methods CPNE1 expression in prostate cancer was analyzed using Gene Expression Omnibus (GEO) databases. The Cancer Genome Atlas (TCGA) dataset was used to investigate the association of CPNE1 expression with TRAF2 expression in prostate cancer. The association of CPNE1 expression with recurrence-free survival in patients was also analyzed using the TCGA dataset. Immunohistochemistry assay was performed to examine CPNE1 expression in 65 normal prostate samples and 114 prostate cancer samples. The recurrence-free survival in patients was evaluated using Kaplan-Meier curves and log-rank test. In addition, multivariate and univariate analyses of prognostic factors were investigated by Cox regression. The effect of CPNE1 on TRAF2 expression was explored in human prostate cancer DU-145 cells. Results Our results showed that expression level of CPNE1 is higher in prostate cancer than in normal prostate tissues (P=0.006). In the GSE35988 dataset, CPNE1 expression was found to be upregulated in castration-resistant prostate cancer compared with non-castration-resistant prostate cancer (P<0.001). Furthermore, we found that CPNE1 high expression was significantly related to tumor stage, Gleason score, and poorer biochemical recurrence-free survival in prostate cancer patients. Co-expression analysis of TCGA data showed that CPNE1 is significantly associated with TRAF2 expression. CPNE1 overexpression can upregulate TRAF2 expression in prostate cancer DU-145 cells as determined by Western blotting and immunofluorescence assays. Conclusions Overall, our findings suggest that CPNE1 is a valuable prognostic marker for evaluating recurrence-free survival and is positively related to TRAF2 expression in prostate cancer.

Abstract
CPNE3, a member of a Ca2+‐dependent phospholipid‐binding protein family, was identified as a ligand of ERBB2 and has a more general role in carcinogenesis. Here, we identified the prognostic significance of CPNE3 expression in acute myeloid leukemia (AML) patients based on two datasets. In the first microarray dataset (n = 272), compared to low CPNE3 expression (CPNE3low), high CPNE3 expression (CPNE3high) was associated with adverse overall survival (OS, P < 0.001) and event‐free survival (EFS, P < 0.001). In the second independent group of AML patients (TCGA dataset, n = 179), CPNE3high was also associated with adverse OS and EFS (OS, P = 0.01; EFS, P = 0.036). Notably, among CPNE3high patients, those received allogenic hematopoietic cell transplantation (HCT) had longer OS and EFS than those with chemotherapy alone (allogeneic HCT, n = 40 vs chemotherapy, n = 46), but treatment modules played an insignificant role in the survival of CPNE3low patients (allogeneic HCT, n = 32 vs chemotherapy, n = 54). These results indicated that CPNE3high is an independent, adverse prognostic factor in AML and might guide treatment decisions towards allogeneic HCT. To understand its inherent mechanisms, we investigated genome‐wide gene/microRNA expression signatures and cell signaling pathways associated with CPNE3 expression. In conclusion, CPNE3high is an adverse prognostic biomarker for AML. Its effect may be attributed to the distinctive genome‐wide gene/microRNA expression and related cell signaling pathways.

Exp Cell Res 2017; 356:85-92.

Abstract
Copine1 (CPNE1), known as a calcium-dependent membrane-binding protein, has tandem C2 domains and an A domain. We previously demonstrated that CPNE1 directly induces neuronal differentiation via Protein kinase B (AKT) phosphorylation in the hippocampal progenitor cell line, HiB5. To better understand its cellular function, we carried out a yeast two-hybrid screening to find CPNE1 binding partners. Among the identified proteins, 14-3-3γ appears to directly interact with CPNE1. Between CPNE1 and 14-3-3γ, the physical interaction as well as the specific binding regions of CPNE1 was confirmed in vitro and in vivo. Furthermore, among the seven 14-3-3 isotypes, only 14-3-3γ directly interacts with CPNE1. Our results also demonstrate that AKT phosphorylation, neurite outgrowth and expression of the neuronal marker protein are increased when 14-3-3γ is overexpressed in CPNE1 high expressed HiB5 cells. Furthermore, the neighboring Ser54 amino acids residue of C2A domain in CPNE1 has an important role in binding with 14-3-3γ, and in differentiation-related function of CPNE1. Moreover, mutation of Ser54 amino acids residue in CPNE1 effectively decreased association with 14-3-3γ and neuronal differentiation of HiB5 cells. Collectively, our findings indicate that 14-3-3γ regulates the differentiation ability of CPNE1 through the binding with C2A domain of CPNE1 in HiB5 cells.
