Redefining the Scope of Targeted Protein Degradation: Translational Opportunities in Hijacking the Autophagy-Lysosome Pathway

Katelyn Cassidy et al.

Summary: The development of multi-specific targeted protein degradation (TPD) therapies has enabled the targeting of previously inaccessible proteins. While the main TPD modalities - molecular glues and proteolysis targeting chimeras (PROTACs) - have been widely adopted, they have limitations. Not all disease-relevant targets are suitable for degradation via the ubiquitin proteasome system (UPS), leading to the emergence of alternative TPD strategies such as the autophagy-lysosome system (ALS). These ALS-mediated degradation techniques, including ATTEC, AUTAC, and LYTAC, greatly expand the clinical utility of TPD.

Summary: Antibody-drug conjugates (ADCs) have been approved as anticancer drugs for both solid and hematological malignancies, but only a few have shown survival improvements over standard treatment. The most promising partners for ADCs are those that have additive or synergistic effects on tumor cells without overlapping toxicities. Co-administration with antiangiogenic compounds, HER2-targeting drugs, DNA-damage response agents, and immune checkpoint inhibitors (ICIs) are active candidates. The next generation of ADCs, with tumor-specific targets, improved conjugation technologies, and novel linkers and payloads, brings hope for combinatorial approaches.

These ligands have corresponding chemoselective conjugation chemistry and, upon successful cellular delivery, released native cargos were predominantly localized inside mitochondria. Delivery of doxorubicin to mitochondria resulted in potent cell cytotoxicity, disruption of mitochondrial membrane potential, and ultimately apoptosis, paving the way for future mitochondrion-targeted therapy.
