Total RNA was extracted using TRIzol reagent (Invitrogen) and quantified by NanoDrop-100 spectrophotometer. Real-time quantitative PCR was performed with an iQ5 (Bio-Rad Laboratories) [8 (link)]. TaqMan quantitative PCR assays (Applied Biosystems, Life Technologies) were run using primers/probes: TNF (Mm00443258 or Hs01113624), ADAM10 (Mm00545742 or Hs00153853), ADAM17 (Mm00456428 or Hs01041915), 18s (Mm03928990), and GAPDH (Hs02758991). Fold variation analyzed using delta-delta Ct (∆∆Ct) formula [18 (link)].
Proteins were assessed by western blot [8 (link)] using rabbit-anti-β-actin peroxidase (Sigma-Aldrich) or anti-ADAM17 (Abcam) followed by HRP-anti-rabbit IgG and detected with SuperSignal West Pico Chemiluminescent Substrate (Thermo Scientific).
