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: 1.6 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: 2.2 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: 0.3 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: 0.00058 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: 0.33 SJR: 0.345 SNIP: 0.46 CiteScore™:: 2.5 H-Index: 67

摘要

Fluorescence in situ hybridization and immunocytochemical techniques have contributed significantly to our current understanding of how transcription, RNA processing, and RNA transport are spatially and temporally organized in the cell nucleus. New technologies enabling the visualization of nuclear components in living cells specifically advanced our knowledge of the dynamic aspects of these nuclear processes. The picture that emerges from the work reviewed here shows that the positioning of genes within the three-dimensional nuclear space is of crucial importance, not only for its expression, but also for the efficient processing of its transcripts. Splicing factors are recruited from speckles to sites of active transcription, which can be present within, at the periphery, or at a relatively large distance from speckles. Furthermore, results are discussed showing that transcripts are exported by means of random diffusion.
