I want to know whether pathways named differently do have intersections in a way. For example, I can see "TGFβ pathway" in "pathways in cancer". Can anyone tell me more about it?
its because KEGG relate the fuction p/e of a protein not only in the pathway you are searching but in all pathways incuding diseases etc etc--- in brief are pathways of the collection of molecular interactions and reactions
My understanding is that the names are just names and the letters may not always directly relate to the signalling pathway. The key is to see what several pathways involved in a disease have in common and target that.
