Abstract
Objectives. Among airway complications, posttransplantation infections are related to
impaired mucociliary clearance, which may represent a toxicity of cyclosporine (CsA), a
potent, widely used immunosuppressive drug after organ transplantations. Since several
recent studies have demonstrated CsA treatment to directly induce apoptosis in several
cell types, we investigated its effects on airway cells using the human bronchial epithelial
cell line BEAS-2B.
Methods. Proliferation was measured by using a Cell Counting Assay Kit by exposing
cells to CsA (0, 10, 30, 50, or 100 g/mL). Apoptotic cells were identified using
fluorescence microscopy after 4=, 6-diamidino-2-phenylidole (DAPI) staining. Western
blot analysis was performed to evaluate the contents of poly(adenosine diphosphate-
ribose) polymerase (PARP), p27, Bcl-2, and caspase-3.
Results. Cell viability decreased dependent on the CsA concentration: 100.00 0.01%
with 0 g CsA as control; 98.65 0.02% with 10 g(P .05 vs control); 95.41 0.05%
with 30 g(P .05 vs control); 38.84 0.04% (P .001 vs control) with 50 g; and
15.28 0.05% with 100 g(P .001 vs control). Apoptotic cells detected with DAPI
showed chromatin condensation and nuclear fragmentation. CsA induced p27 and p53, as
well as degradation of 116-kd PARP into an 89-kd fragment.
Conclusion. CsA induced apoptosis in human bronchial epithelial cells.
