Valproic acid for selective HDAC1 inhibition, RGFP966 for selective HDAC3 inhibition, LMK-235 for selective HDAC4 inhibition, Tubastatin A for selective HDAC6 inhibition, PCI-34051 for selective HDAC8 inhibition, and TSA for pan-HDAC inhibition were purchased from Selleckchem (Houston, TX, USA) and were used in various treatment groups. The chemicals were dissolved in dimethyl sulfoxide (DMSO; Sigma-Aldrich, St. Louis, MO, USA). Vehicle (DMSO) was used in control groups. 2 d before lung allograft transplant, the lung allograft recipient mice were treated with the vehicle, Valproic acid (300 mg/kg) 70 (link),71 (link), RGFP966 (10 mg/kg) 72 (link),73 (link), LMK-235 (20 mg/kg) 74 (link), Tubastatin A (30 mg/kg) 75 (link), PCI-34051 (40 mg/kg) 76 (link), or TSA (1 mg/kg) 77 (link) by intraperitoneal injection every day until lung allograft loss which was determined by Micro-Computer Tomography (micro-CT) Scans, unless specified.
