| Abstract | Human telomerase reverse transcriptase (hTERT), a ribonucleoprotein, is reported as an important complex, which is required for stability of DNA molecular structure at the rear of the chromosome. Until now, hTERT has been linked to cell immortalization and tumorigenesis. A couple of articles have been published about the telomerase function in the gliomas; however, these results are conflicting in some degree. Thus, it is crucial to perform a meta-analysis to identify their real actions. We included eligible articles, and estimated odds ratios (ORs) with 95 % confidence intervals (95 % CIs). In our meta-analysis, all 15 eligible articles included 932 patients. Results from 10 studies on WHO grade showed that high hTERT gene or protein expression in glioma tissues was obviously related to high WHO grade (III + IV) (OR 2.45, 95 % CI 1.92–3.13; p = 0.000). What is more, hTERT expression was not associated with old age (OR 0.91, 95 % CI 0.72–1.16; p = 0.448) as well as gender (OR 1.06, 95 % CI 0.82–1.37; p = 0.664). Importantly, hTERT expression was significantly associated with 5-year overall survival (OS; n = 3; hazard ratio (HR) 2.25, 95 % CI 1.36–3.70; p = 0.002) of glioma patients. No heterogeneity was found in all studies. In conclusion, this meta-analysis suggests that hTERT is significantly associated with high glioma grade and poor 5-year overall survival, and pathological test of hTERT mRNA and protein in glioma tissues should be suggested as criteria of glioma grade in the clinical practice. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
