I would like to compare the difference between the 2 type of lung cancer , adenocarcinoma and squamous cell carcinoma in team of Long non coding RNA (LncRNA) , however, i have no idea where i can freely access the expression profile for adenocarcinoma (tumor sample).
What do you mean with expression profile? Are you looking for RNA-seq raw datasets? Try to be as informative and precise as possible when asking questions.
