Total RNA was extracted from MEC-Ctr and MEC-p66 cells, generated as previously described [12 (
link)], using the
RNeasy Micro Kit (Qiagen, Valencia, CA) and subjected to gene array profile analysis using Affymetrix HuGene-2_0-st-v1 arrays (carried out by the Microarray Unit at Cogentech, Milan, Italy).
Total RNA was extracted from B cells from healthy donors, CLL patients, MEC-1 or EBV-B cells using the
RNeasy Plus Mini Kit (Qiagen) and retrotranscribed using the
iScript™ cDNA Synthesis Kit (Bio-Rad, Hercules, CA). Three independent reverse transcription reactions were performed on each sample. qRT-PCR was performed in triplicate on each cDNA on
96-well optical PCR plates (Sarstedt, Nümbrecht, Germany) using
SSo Fast EvaGreenR SuperMix (Bio-Rad) and a
CFX96 Real-Time system (Bio-Rad). Results were processed and analyzed using
CFX Manager Version 1.5 software (Bio-Rad). Transcript levels were normalized to housekeeping controls.
HPRT was used as housekeeping control for all qRT-PCR analyses with the exception of the experiments involving treatment with LSF, for which
ACTB (β-actin) was used as this treatment resulted in alternations in
HPRT mRNA levels. The primers used to amplify the cDNA fragments are listed in Supplementary Table S2.
