Increased mitophagy markers in the MDA-MB-231 cell line. (A) Representative blots. (B–E) Expression of mitophagy markers, PTEN-induced kinase 1 (PINK1), n = 6; ubiquitin-binding protein p62 (p62), n = 3; Parkin, n = 3; and microtubule-associated proteins 1A/1B light chain 3B (LC3-II), n = 3. Densitometry values were normalized by Ponceau S red staining. The data are presented as mean ± SD. * p < 0.05, ** p < 0.01.
