Thirty mg of tissue was homogenised using a Precellys 24 bead mill homogeniser using ceramic 1.4mm beads for soft tissue homogenising with 600ul of RTL plus Buffer with 10µl/ml of β-Mercaptoethanol and 5µl/ml of reagent DX (Qiagen). RNA and DNA was extracted from the tissue using a QIAcube using an AllPrep DNA/RNA Mini Kit following the manufacturer’s recommended protocol.
