Experimental Protocol


RNA was extracted from 2-4 sections of 4-μm thick, FFPET sections. Non-tumor elements were removed by manual microdissection before transfer to the extraction tube guided by hematoxylin and eosin stained slides. The samples with RNA concentrations of <40 ng/μL, A260/A280 ratios <1.5 or A260/230 ratios <1.0 were considered as inadequate samples and were excluded from the analysis.
