Disabled 1 (Dab1) is an adapter protein for very low density lipoprotein receptor (VLDLR) and apolipoprotein E receptor 2 (ApoER2) and an integral component of the Reelin pathway which orchestrates neuronal layering during embryonic brain development. Activation of Dab1 is induced by binding of Reelin to ApoER2 and VLDLR and phosphorylation of Dab1 mediated by Src family kinases. Here we show that Dab1 also acts as an adaptor for epidermal growth factor receptor (EGFR) and can be phosphorylated by epidermal growth factor (EGF) binding to EGFR. Phosphorylation of Dab1 depends on the kinase activity of EGFR constituting a signal pathway independent of Reelin and its receptors.

Highly Optimized CNS Penetrant Inhibitors of EGFR Exon20 Insertion Mutations.

Despite recent advances in the inhibition of EGFR (epidermal growth factor receptor), there remains a clinical need for new EGFR Exon20 insertion (Ex20Ins) inhibitors that spare EGFR WT. Herein, we report the discovery and optimization of two chemical series leading to ether and biaryl as potent, selective, and brain-penetrant inhibitors of Ex20Ins mutants. Building on our earlier discovery of alkyne which allowed access to CNS property space for an Ex20Ins inhibitor, we utilized structure-based design to move to lower lipophilicity and lower CL compounds while maintaining a WT selectivity margin.

The intracellular protozoan Toxoplasma gondii manipulates host cell signaling to avoid targeting by autophagosomes and lysosomal degradation. Epidermal Growth Factor Receptor (EGFR) is a mediator of this survival strategy. However, EGFR expression is limited in the brain and retina, organs affected in toxoplasmosis.

The cysteine-rich epidermal growth factor ligand domain 2 protein (CRELD2) is associated with pathways that regulate epithelial-to-mesenchymal transition, a critical process driving cancer metastasis. This study aimed to determine the prognostic value of CRELD2 status on survival outcomes in triple-negative breast cancer (TNBC). Seventy patients were included in the study.

In gastric cancer, the relationship between human epidermal growth factor receptor 2 (HER2), the cyclic GMP-AMP synthase-stimulator of the interferon genes (cGAS-STING) pathway, and autophagy remains unclear. This study examines whether HER2 regulates autophagy in gastric cancer cells via the cGAS-STING signaling pathway, influencing key processes such as cell proliferation and migration. Understanding this relationship could uncover new molecular targets for diagnosis and treatment.
