TNFAIP6 and acute respiratory distress syndrome: PTGS2 had increased transcription for both hydrostatic and ARDS pulmonary edema fluid (~20-fold and 1000-fold increase, p values 0.002 and 0.02, respectively), but TSG-6 transcription was induced solely by ARDS pulmonary edema fluid (6-fold increase, p value 0.02).
