ABSTRACT
PURPOSE: The present study investigated whether an autophagic process is involved in the apoptotic death of human tenon's capsule fibroblasts (HTCFs) caused by mitomycin-C. METHODS: An autophagic phenotype was tested using fluorescence microscopy and flow cytometry with specific biological staining dyes including monodansylcadaverine and acridine orange and microtubule-associated protein 1 light chain 3 (LC3). RESULTS: Treatment with mitomycin-C (0.4 mg/ml) increased the acidic vesicular organelles of tenon's capsule fibroblasts in a time dependent manner. Mitomycin-C induced both LC3-II cleavage and beclin-1 expression. 3-MA, a pharmacological inhibitor of autophagy, inhibited the mitomycin-C induced increase of acidic vesicular organelleS. CONCLUSIONS: Autophagy was induced with 0.4 mg/ml mitomycin-C in tenon's capsule fibroblasts. And, autophagic mechanisms may be involved in the early stage of apoptosis of fibroblasts.
