Hello to everyone,

I want to compare gene expression (and gene networks) for gastric in different conditions:

1- normal and healthy (no cancer - no helicobacter)

2- gastric cancer

3- no cancer but helicobacter  ( I have no idea how to search for this one)

I don't know where to start? 

I found this post ( https://www.biostars.org/p/103607/) which introduces Cancer Gene Expression DataBase  (CGED) which will help me for the first case (still I'm not sure how to exclude helicobacter from search), but I need to download microarrays for the three mentioned conditions. How should I be sure that they are comparable?

** One more limit that I have is that I have a set of specific genes that I need to make sure are available in all microarrays. 

Any help is appreciated. Thanks!

Have you checked GEO?

You`d better do your own research and grow your own data. I can advise to use software (I had experience in that): Expander, MeV and Genesis with Cluster are the best from free ones. And if you aware how to program, use Bioconductor R packages. I think there are some packages for data retrieval. Regarding specific data of gastric cancer, contact the authors of relevant articles from SciDirect, MEDLINE and DOJA search. Cheers....
