RNA was isolated from whole mouse lung tissue or Calu-3 cells using the RNeasy Spin column kit (Qiagen #75144) then reverse transcribed using the cDNA Reverse Transcription Kit (Applied Biosystems #4308228) as previously described46 (link). Gene expression was reported as fold change over WT-saline condition normalized to GAPDH in mouse lung tissues or OAZ1 for Calu-3 cells and calculated using the double delta CT (2∆∆CT) method as previously described7 (link),8 (link),46 (link).
