The establishment of human malignant tumor cell lines can provide abundant experimental materials for understanding the biological characteristics of tumors, studying the carcinogenesis, molecular genetics and the mechanism of metastasis and evolution. In this study, a novel cell line designated ZJB-ENC1 has been established from poorly differentiated endometrioid adenocarcinoma. Cytological results showed monolayer-cultured cells were polygonal in shape and a piling-up tendency without contact inhabitation. Immunohistochemistry analysis showed that the cells were negative for ER, PR, c-erbB2, E-CAD, CD117, and OCT3/4, but strongly positive for PTEN and P16. Meanwhile, the tumorigenicity of ZJB-ENC1 was confirmed by subcutaneous transplantation of the cells into a xenograft mouse model. In addition, the results of the whole exome sequencing revealed a unique genomic characteristic of ZJB-ENC1 cells, all common and novel SNPs and InDels were identified. In conclusion, this new stable cell line may promote basic and clinical research on endometrial cancer (EC).

Background: Long noncoding RNA associated with poor prognosis of hepatocellular carcinoma (AWPPH) is a novel oncogene and dysregulated in a variety of human cancers. It has been revealed to be associated with the clinicopathological features and prognosis. However, the prognostic value of AWPPH in various cancers remains unclear. Therefore, we perform this meta-analysis to evaluate the relationship between AWPPH expression and clinical outcomes in human cancers.Methods: Comprehensive literature search was performed in PubMed, Web of Science, CNKI and Wangfang databases, and eligible studies were obtained according to the inclusion and exclusion criteria. The pooled hazard ratios (HRs) and odds ratios (ORs) were applied to assess the clinical value of AWPPH expression for overall survival (OS) and clinicopathological features.Results: A total of 19 articles including 1699 cancer patients were included in the study. The pooled results demonstrated that evaluated AWPPH expression was positively related to a poorer overall survival of patients with cancers (HR=1.79, 95%CI: 1.44-2.14, P<0.001). Subgroup analysis revealed that tumor type and sample size affect the predictive value of AWPPH on OS, whereas cut-off value and HR estimation method have no impact on it. In addition, the pooled data also showed that AWPPH was positively linked to advanced TNM stage (OR=2.67, 95%CI: 1.86-3.83, P<0.001) , bigger tumor size (OR=2.64, 95%CI:1.47-4.73, P=0.001), macro-vascular invasion (OR=2.08, 95%CI: 1.04-4.16, P=0.04) and lymph node metastasis (OR=2.68, 95%CI: 1.82-3.96, P<0.001). Moreover, the results of the trim and fill analysis confirmed the reliability of our finding. Conclusions: Upregulation of AWPPH was associated with advanced TNM stage, bigger tumor size, worse lymph node metastasis, macro-vascular invasion, and shorter overall survival, suggesting that AWPPH may serve as a biomarker for prognosis and clinicopathological characteristics in human cancers.

The pooled results demonstrated that evaluated AWPPH expression was positively related to a poorer overall survival of patients with cancers (HR=1.79, 95%CI: 1.44-2.14, P&lt;0.001). Subgroup analysis revealed that tumor type and sample size affect the predictive value of AWPPH on OS, whereas cut-off value and HR estimation method have no impact on it. In addition, the pooled data also showed that AWPPH was positively linked to advanced TNM stage (OR=2.50, 95%CI: 1.94-3.22, P&lt;0.001) , bigger tumor size (OR=2.64, 95%CI:1.47-4.73, P=0.001), macro-vascular invasion (OR=2.08, 95%CI: 1.04-4.16, P=0.04) and lymph node metastasis (OR=2.68, 95%CI: 1.82-3.96, P&lt;0.001). Moreover, the results of the trim and fill analysis confirmed the reliability of our finding. Conclusions: Up-regulation of AWPPH was associated with advanced TNM stage, bigger tumor size, worse lymph node metastasis, macro-vascular invasion, and shorter overall survival, suggesting that AWPPH may serve as a biomarker for prognosis and clinicopathological characteristics in human cancers among the Chinese population.

Background: Long noncoding RNA small nucleolar RNA host gene 20 (SNHG20) is a novel oncogene and dysregulated in a variety of human cancers. It has been revealed to be associated with the clinicopathological features and prognosis. However, the prognostic value of SNHG20 in various cancers remains unclear. Therefore, we performed this meta-analysis to evaluate the relationship between SNHG20 expression and clinical outcomes in human cancers.Methods: Comprehensive literature search was performed in PubMed, Web of Science, CNKI and Wangfang databases, and eligible studies were obtained according to the inclusion and exclusion criteria. The pooled hazard ratios (HRs) and odds ratios (ORs) were applied to assess the clinical value of SNHG20 expression for overall survival (OS) and clinicopathological features.Results: A total of 16 articles including 1190 cancer patients were included in the study. The pooled results demonstrated that evaluated SNHG20 expression was positively related to a poorer OS of cancers (HR=2.36, 95%CI: 1.85-2.87, P<0.001). Subgroup analysis revealed that SNHG20 overexpression was closely related to the low OS of patients with the digestive system cancer (HR=2.92, 95%CI: 1.96-3.88, P<0.001), sample size >80 (HR=2.42, 95%CI: 1.69-3.14, P<0.001), direct HR estimation method (HR=2.65, 95%CI: 1.78-3.52, P<0.001), and median ratio as cut-off value (HR=2.21, 95%CI: 1.60-2.83, P<0.001). In addition, the pooled data also showed that SNHG20 was positively linked to lymph node metastasis (LNM) (OR=1.65, 95%CI: 1.21-2.26, P=0.002), distant metastasis (DM) (OR=1.76, 95%CI: 1.10-2.83, P=0.02), and advanced TNM stage (OR=1.79, 95%CI: 1.34-2.39, P<0.001). Moreover, the results of the trim and fill analysis confirmed the reliability of our finding. Conclusions: Upregulation of SNHG20 was associated with advanced TNM stage, worse LNM and DM, and shorter OS, suggesting that SNHG20 may serve as a biomarker for prognosis and clinicopathological characteristics in human cancers.
