Here's one possible strategy using NCBI's Entrez search engine:
Go to Entrez:PubMed :
In the search box at the top, enter:
Eleven papers are returned. On the "Display" pull-down menu,
select "Nucleotide Links" .
10 human RefSeq mRNA sequence will be returned.
Use the "Display" pull-down menu and select "SNP Links" .
103 single nucleotide polymorphisms are returned.
Note that this is a very indirect strategy: The SNPs that are
obtained this way may not relate specifically to the MCF7 cell
line. Rather, the SNPs are associated with those RefSeq records
which cite PubMed articles which have the words "MCF7" and
If the results are not helpful, you might want to contact NCBI's
help desk, to see if they can recommend another approach:
