Extraction protocol
Total RNA was isolated using the TRIzol reagent and following the manufacturer's RNA isolation protocol (Invitrogen, #15596). One milliliter of TRIzol solution was added to each tube containing the frozen tissue block, and the tissue was homogenized by 10 passages through an 18.5 ga syringe needle. After centrifugation, the RNA was precipitated from the aqueous layer, washed, and dissolved in RNase-free water. RNA concentration and integrity were assessed by spectrophotometry and gel electrophoresis. The RNA samples were stored at 80°C.
