+<h3> About RatsPub ...</h3>
 
-<p>RatsPub searches PubMed to find abstracts containing genes of interest and a list of curated addiction-related keywords. The abstracts corresponding to these returned PMIDs are then retrieve from a <a href="https://dataguide.nlm.nih.gov/edirect/archive.html">local archive of the PubMed</a>. No limit on the date of publication is set. Each abstract is then broken down into sentences, which are then filtered by genes and keywords.

-<p> The top 200 addiction genes were obtained by searching All human genes against addiction related keywords. The archived results for these top addiction genes can be accessed via the <a href="/allTopGenes">Addiction Genes</a> link. 
+<p> The top 200 addiction genes were obtained by searching 29,761 human genes against addiction related keywords. To ensure comprehensive coverage, gene alias obtained from NCBI gene database were included in the search. The results were extensively curated to remove those alias that matched words that were not gene name or wrong genes. Some incorrect results remained because the same name also produced correct results. The archived results for these top addiction genes can be accessed via the <a href="/allTopGenes">Addiction Genes</a> link.

These gene-keyword relationships are presented as an interactive graph that can efficiently  answer the question <b>"What do we know about these genes and addiction?" </b>
+
+<p> In addition, clicking gene names in the graph will launch a new search for sentences containing the target gene and 200 addiction-related genes. These results help to answer the question <b>"Are there  genes that can link my gene of interest to addiction?"  </b>
