GZMB and newborn respiratory distress syndrome: Analysis of GR isoform abundance showed once more that GRα was the most predominant splice variant in CBWBCs (86.7% and 83.4% in no-RDS and RDS groups, respectively), followed by GRP (7.7% and 10.3% in no-RDS and RDS groups, respectively), GRγ (4.5% and 5.3% in no-RDS and RDS groups, respectively), and GRβ (1.1 and 0.9% in no-RDS and RDS groups, respectively) (Figure 4F).
