The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

ABSTRAKT

Long noncoding RNAs (lncRNAs) have been reported to be involved in cancer initiation and evolution, including colorectal cancer (CRC). Nuclear-enriched abundant transcript 1 (NEAT1) exerts important functions in multiple cancers; however, the specific modulatory mechanism in CRC demands in-depth exploration. The expression levels of NEAT1, microRNA-195-5p (miR-195-5p), and centrosomal protein 55 (CEP55) were examined using quantitative real-time polymerase chain reaction (qRT-PCR), and protein expression of CEP55 was detected by Western blot assay. Cell proliferation and apoptosis were measured by 3-(4,5-dimethylthiazole-2-y1)-2,5-diphenyl tetrazolium bromide (MTT) assay and flow cytometry. Transwell migration and invasion assays were applied to evaluate cell metastasis ability. Dual-luciferase reporter assay was used to analyze the correlation among NEAT1, miR-195-5p and CEP55. The expression of NEAT1 was up-regulated in CRC tissues and cells, and overall survival was lower with high expression of NEAT1. Knockdown of NEAT1 repressed cell proliferation, migration, and invasion, while inducing apoptosis in CRC cells. NEAT1 targeted miR-195-5p and inhibited the expression of miR-195-5p. Silence of NEAT1 inhibited CRC cell proliferation, migration, and invasion, and promoted apoptosis by up-regulating miR-195-5p. MiR-195-5p targeted and suppressed CEP55 expression, and CEP55 reverted the effects induced by miR-195-5p. NEAT1 regulated the expression of CEP55 through miR-195-5p. NEAT1 promotes colorectal cancer cellular processes by regulating CEP55 expression via the sponging of miR-195-5p. Therefore, NEAT1 might play a crucial role in CRC treatments.
