Homogenisation was performed according to the methodology described in the previous studies [14 (link), 16 (link)]. The samples of the tumour and NT were weighed and homogenised using a PRO200 homogeniser (PRO Scientific Inc., Oxford, CT, USA) at 10,000 rpm in 9 volumes of PBS (EURx, Gdansk, Poland). After homogenisation, sonification with an ultrasonic cell disrupter was performed (UP100H, Hielscher Ultrasonics GmbH, Teltow, BB, Germany).
