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!
