[BioC] MySQL databases offering gene expression, esp. toxicogenomics data

[N. Goodacre]

Dear Bioconductor mailing group,

  I would like to ask if anyone knows of a solid toxicogenomics database 
under MySQL - i.e. one with expression profiles for a number of toxicities. 
If it helps, the toxicities I am interested in are hepatotoxicities. I am a 
little shaky on just who gets to use MySQL and who does not, especially for 
Bioinformatians, so perhaps if someone could run over this for me, that 
would be greatly appreciated as well.

  Sincerely,

Norman Goodacre
