SQSTM1 and neoplasm: To explore the potential involvement of mtGR in tumor progression, via regulation of autophagy, comparative studies on the differential expression of autophagy-related molecules, such as BCL2/Adenovirus E1B 19 kDa protein-interacting protein 3-like (BNIP3L, BINIP3L/NIX), LC3II/LC3I (LC3B: microtubule-associated proteins 1A/1B light chain 3B), p62, and Beclin 1 (BECN1), were performed, applying Western blot analysis.
