X., Wang, Z. J., Wang, J., Xu, A. M., Zhang, J. Y., He, X. M., Pan, Y. S., Cheng, G., Qin, C., Hua, L. X., and Wang, Z. J., Prognostic significance of long non-coding RNA MALAT-1 in various human carcinomas: a meta-analysis, vol. 15, p. -, 2016.

The long non-coding RNA MALAT-1 plays an important role in cancer prognosis. The present research aimed to elucidate its precise predictive value in various human carcinomas. A quantitative meta-analysis was performed by searching PubMed, Embase, Web of Science, and Cochrane Library (most recently, January 2015) databases, and extracting data from studies that investigated the association between MALAT-1 expression and survival outcomes in patients of various cancers. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated as a measure of generalized effect.

Gli1 expression in pancreatic ductal adenocarcinoma and its clinical significance

Y. Abula, Yi, C., Wang, X. - Y., Wang, M., Qin, R. - Y., Guo, Y. - Q., Lin, H., and Li, H. - J., Gli1 expression in pancreatic ductal adenocarcinoma and its clinical significance, vol. 14, pp. 12323-12329, 2015.

The aim of this study was to explore the correlation between the expression levels of Gli1 and p53 in pancreatic ductal adenocarcinoma (PDAC) and its pathological significance. Immunohistochemistry (IHC) was employed to measure the expression level of Gli1 and p53 in 85 sets of paraffin-embedded PDAC and corresponding para-carcinoma tissue specimens. The relationship between these results and the respective patients’ clinicopathologic parameters was analyzed.

Correlation between non-metastatic protein 23 expression and clinicopathological features of colorectal cancer in Asians

J. W. Fu and Chu, X. Q., Correlation between non-metastatic protein 23 expression and clinicopathological features of colorectal cancer in Asians, vol. 14, pp. 15597-15608, 2015.

The current meta-analysis was performed to investigate the association between non-metastatic protein 23 (NM23) expression, tumor pathology, and disease prognosis in colorectal cancer (CRC) among Asians. English and Chinese language-based electronic databases (e.g., PubMed, EBSCO, Ovid, Springerlink, Wiley, Web of Science, Wanfang databases, China National Knowledge Infrastructure, VIP databases) were searched using search terms to identify published studies relevant to NM23 and CRC with immunohistochemistry.

Prognostic role of microRNA-100 in patients with bladder cancer

Y. H. Cao, Zhang, H. H., Xu, H. F., Duan, Y. J., Li, Q., and Huang, B., Prognostic role of microRNA-100 in patients with bladder cancer, vol. 14, pp. 15948-15954, 2015.

We investigated the clinical significance and prognostic value of microRNA-100 (miR-100) in bladder cancer. Quantitative real-time polymerase chain reaction was used to analyze the expression of miR-100 in 92 pairs of human bladder cancer and adjacent normal tissue samples. Overall survival (OS) curves were plotted using the Kaplan-Meier method and were evaluated for statistical significance using a log-rank test. The significance of different variables with respect to survival was analyzed using the multivariate Cox proportional hazard model.

Reduced miRNA-218 expression in pancreatic cancer patients as a predictor of poor prognosis

B. - S. Li, Liu, H., and Yang, W. - L., Reduced miRNA-218 expression in pancreatic cancer patients as a predictor of poor prognosis, vol. 14, pp. 16372-16378, 2015.

microRNA-218 (miR-218) is a vertebrate-specific miRNA that plays a crucial role in tumorigenesis and tumor progression. This study analyzed the miR-218 expression level and clinical significance in pancreatic cancer. One hundred and seven pairs of pancreatic cancer and adjacent normal tissues were analyzed by quantitative reverse-transcriptase polymerase chain reaction. The correlation between miR-218 expression and clinicopathological characters was determined by the two-sample Student t-test.

Expression of microRNA-106b and its clinical significance in cutaneous melanoma

N. Lin, Zhou, Y., Lian, X., and Tu, Y., Expression of microRNA-106b and its clinical significance in cutaneous melanoma, vol. 14, pp. 16379-16385, 2015.

MicroRNA-106b (miR-106b) is overexpressed in various types of cancers and is associated with the regulation of carcinogenic processes. However, its clinical significance in cutaneous melanoma has not been reported. qRT-PCR was performed to examine the expression of miR-106b in 15 cases of dysplastic nevi, 17 cases of melanoma metastases, and 97 cases of primary cutaneous melanoma tissue samples. Survival rate was determined with Kaplan-Meier and statistically analyzed with the log-rank method between groups. Survival data were evaluated through multivariate Cox regression analysis.

R337H mutation of the TP53 gene as a clinical marker in cancer patients: a systematic review of literature

L. M. Borges and Ayres, F. M., R337H mutation of the TP53 gene as a clinical marker in cancer patients: a systematic review of literature, vol. 14, pp. 17034-17043, 2015.

The germline R337H mutation of the TP53 gene has been associated with the development of many tumor types. This systematic review of literature investigated the association between the R337H mutation and the patients’ family history and its predictive and prognostic value in cancer. Data were collected from articles archived in the PubMed, LILACS, MEDLINE, IBECS, and SciELO databases.

Decreased miR-134 expression and its tumor-suppressive function in human osteosarcoma

Y. Bao, Peng, L., Ma, J., Liu, K., and Li, W., Decreased miR-134 expression and its tumor-suppressive function in human osteosarcoma, vol. 14, pp. 16771-16781, 2015.

Dysregulation of microRNA (miR) is often associated with cancer development and progression. Aberrant expression of miR-134 has been found in some types of cancer. However, its expression and function in osteosarcoma remain unclear. The aim of this study was to explore the effects of miR-134 in osteosarcoma tumorigenesis and development. The expression level of miR-134 was quantified by real-time reverse transcription-polymerase chain reaction in human osteosarcoma cell lines and tissues.

Prognostic value of miR-141 downregulation in gastric cancer

Y. B. Lu, Hu, J. J., Sun, W. J., Duan, X. H., and Chen, X., Prognostic value of miR-141 downregulation in gastric cancer, vol. 14, pp. 17305-17311, 2015.

Previous research has shown that microRNA-141 (miR-141) expression levels are associated with survival in several types of cancer. In the present study, we investigated the clinical significance and prognostic value of miR-141 in gastric cancer. Paired tissue specimens (tumor and adjacent normal mucosa) from 95 patients with gastric cancer were obtained at the Department of General Surgery, Xiangya Hospital, Central South University from March 2009 to February 2014.
