| Extraction protocol |
Biopsies were snap-frozen after collection and stored in liquid nitrogen. Frozen sections were taken prior to RNA extraction to confirm the presence of cancerous tissue within the specimens. Only samples in which the malignant component comprised at least 20% of the section area were used in further analyses. Immediately before RNA extraction the biopsies were pulverised using U2 micro-dismembranator U (Braun Biotech). Total RNA was extracted from the resultant frozen tissue powder using TRI-reagent (Sigma) according to the manufacturer's recommendations. Extracted RNA was additionally purified on RNeasy mini columns (Qiagen). RNA quantity and quality was verified on Bioanalyser 2100 (Agilent).
