| Abstract | Long non-coding RNA (lncRNA) is a new class of regulative non-coding RNA, with a length larger than 200 nucleotides. Recent studies found that there are close relations between disregulative lncRNAs and human tumors. However, the clinical significances are largely unknown. In this study, we investigated the lncRNA–Fer-1-like protein 4 (FER1L4) level in gastric cancer tissues and plasma. The FER1L4 level in human tissues and plasma were measured by real-time quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Then, the correlations between the tissue or plasma FER1L4 levels and clinicopathological factors were assessed. A receiver operating characteristic (ROC) curve was constructed for differentiating GC patients from controls. Compared to matched adjacent non-tumorous tissues, FER1L4 expression levels in 91.80 % (56/61) of gastric cancer tissues are significantly decreased. The low FER1L4 level were associated with tumor size (p < 0.001), histologic grade (p = 0.001), general classification (p < 0.001), depth of invasion (p < 0.001), lymphatic metastasis (p < 0.001), distant metastasis (p = 0.003), TNM stage (p < 0.001), vessel or nerve invasion (p < 0.001 or p = 0.003), and serum CA72-4 (p < 0.001). The area under the ROC curve (AUC) was up to 0.778 (p < 0.001) and the sensitivity and specificity were 67.2 and 80.3 %, respectively. Also, plasma FER1L4 was detected by qRT-PCR. Our data show that there was no difference of plasma FER1L4 level between healthy person and preoperative gastric cancer patients, with a sharp decline in 63.9 % (53/83) of gastric cancer patients 2 weeks after surgery (p = 0.028). Taken together, FER1L4 might play a crucial role in human gastric cancer and may be a new potential biomarker for clinical prognosis evaluation. |

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.
