Beginning in mid-February 2008, the 1997-2007 online version of the Science Watch® newsletter, ESI-Topics.com, and in-cites.com, will all be featured together on the redesigned ScienceWatch.com. All previous content from the three sites will be permanently archived, and remain accessible from any existing bookmarks to the archived pages. No new content will be added to this site. Updates and new content (updated biweekly) are available at ScienceWatch.com now.

Overview

Gene silencing, either through a process known as RNA interference or the methylation of DNA, is now among the hottest topics in molecular biology and has been called a new regulatory paradigm in biology. The phenomenon occurs naturally as a gene regulatory mechanism in plants, and animals, and pathogically as an inhibitor of tumor suppressor genes in cancer cells. In functional genomics, gene silencing also shows extraordinary promise as a means of achieving selective interference of gene function and loss-of-function screens on a genome-wide scale.

The list of top 20 papers in gene silencing reflects the diverse nature of this widely occurring phenomenon. One major theme in the list is the elucidation of the mechanisms of RNA interference: unraveling the process by which double-stranded RNA is cleaved into short RNA strands known as siRNA, which in turn work as sequence specific mediators of gene silencing. Another major theme is the analysis of how gene silencing is accomplished in the chromatin of mammalian cells through the methylation of DNA. A quartet of the top papers examine the role of gene silencing in plants as a gene regulator and viral protection mechanism, as well as the counter-mechanisms by which viruses work to suppress post-transcriptional gene silencing. Other highly cited papers discuss the role of DNA hypermethylation as a mechanism of tumor-suppressor inactivation in cancer, and the promise of using gene silencing to interfere selectively with gene function in a wide range of organisms.

Methodology

To construct this database, papers were extracted based on TOPIC search. The keywords used were as follows: 

gene silenc*

The baseline time span for this database is 1993-2003 (fourth bimonthly). The resulting database contained 1,505 papers; 4,540 authors; 48 countries; 365 journals; and 898 institutions.

Rankings

Once the database was in place, it was used to generate the lists of top 20 papers, authors, journals, institutions, and nations, covering a time span of 1993-2003 (fourth bimonthly).

The top 20 papers are ranked according to total cites. Rankings for author, journal, institution, and country are listed in three ways: according to total cites, total papers, and total cites/paper. The paper thresholds used to determine scientist, institution, country, and journal rankings according to total cites/paper were as follows: 7, 6, 7, and 8, respectively. These thresholds correspond to the top 1% of authors, 10% of institutions, 50% of countries and 10% of journals by total papers.
