Indeed, in HER2+ breast cancer, a malignancy where CDK12 is co-amplified with HER2 and its expression correlates with disease status, CDK12 inhibition markedly elevates MYC expression to induce lethality. The dual effects of CDK12 inhibition elucidated herein clarify its role in transcriptional control and have significant translational implications.

After binding to POI, PROTAC can recruit E3 to ubiquitinate POI via ubiquitin-proteasome mediated degradation. In this review, we summarize relevant research results and review that PROTAC can effectively inhibit the proliferation of breast cancer cells by inducing ubiquitination of CDK1, CDK4/6, CDK9, CDK12/13 and their subsequent degradation by proteasomes, which is expected to be a novel approach for the treatment of breast cancer.

Journal: First ATG101-recruiting small molecule degrader for selective CDK9 degradation via autophagy-lysosome pathway. (Pubmed Central) - Jun 9, 2025 Mechanism research revealed that AZ-9 recruits ATG101 to initiate the autophagy-lysosome pathway, and forms autophagosomes through the recruitment of LC3, which then fuses with lysosomes to degrade CDK9 and the partner protein Cyclin T1. These dates validated the existence of non-proteasomal degradation pathway of hydrophobic driven protein degradation strategy for the first time, which might provide research ideas for chemical induction intervention on other types of pathogenic proteins.
