AbstractThe nine human NR3 nuclear receptors translate steroid hormone signals in transcriptomic responses and operate multiple highly important processes ranging from development over reproductive tissue function to inflammatory and metabolic homeostasis. Although several NR3 ligands such as glucocorticoids are invaluable drugs, this family is only partially explored, for example, in autoimmune diseases and neurodegeneration, but may hold therapeutic potential in new areas.

AbstractInfection of cells with high-risk strains of the human papillomavirus (HPV) causes cancer in various types of epithelial tissue. HPV infections are responsible for ~4.5% of all cancers worldwide. Tumorigenesis is based on the inactivation of key cellular control mechanisms by the viral proteins E6 and E7. The HPV E6 protein interacts with the cellular E3 ligase E6AP, and this complex binds to the p53 DNA-binding domain, which results in degradation of p53.

AbstractRecent successes in developing small molecule degraders that act through the ubiquitin system have spurred efforts to extend this technology to other mechanisms, including the autophagosomal-lysosomal pathway. Therefore, reports of autophagosome tethering compounds (ATTECs) have received considerable attention from the drug development community.

A recent study published in Nature by Radko-Juettner and colleagues reports an unexpected mutant-specific synthetic lethality in which the E3 protein ubiquitin ligase DCAF5 specifically degrades mutant but not wild-type SWI/SNF chromatin remodeling complexes.1 DCAF5 contains a likely druggable WDR domain, providing a new avenue for the development of novel therapeutics for aggressive cancers with SMARCB1 loss of function mutations.

AbstractNuclear receptors (NRs) regulate transcription in response to ligand binding and NR modulation allows pharmacological control of gene expression. Although some NRs are relevant as drug targets, the NR1 family, which comprises 19 NRs binding to hormones, vitamins, and lipid metabolites, has only been partially explored from a translational perspective.
