LC3-II/LC3-I ratio in basal conditions.
Fresh semen was washed and proteins were extracted and further resolved in SDS-PAGE (see material and methods section). Immunoblotting was performed with an antibody that recognized both LC3-I and LC3-II proteins. Immunoblotting is a representative image of the protein expression of LC3 from 8 semen donors (lanes numbered from 1 to 8) from a total of 33. LC3-I and LC3-II were measured and autophagy flux was expressed as ratio of LC3-II/LC3-I.
