Aurora Kinase A in High-Risk Retinoblastoma
2026-09-12
A 2024 study in The American Journal of Pathology identifies Aurora kinase A (AURKA) overexpression as a feature of human retinoblastoma associated with histopathologic high-risk factors and poor chemotherapy response. By integrating patient-tissue analysis with genetic, pharmacologic, cell-based, and xenograft models, the work provides a mechanistic rationale for evaluating AURKA-directed strategies in aggressive or refractory disease.

PPARα Inhibits Pyroptosis in Cholestatic Liver Injury
2026-09-10
The reference study identifies a dual anti-pyroptotic mechanism by which PPARα activation protects mice from lithocholic acid-induced cholestatic liver injury. Its findings connect PPARα to both NLRP3/NF-κB signaling and the APAF1/CASPASE-3/GSDME pathway, providing a framework for evaluating PPARα-directed interventions in liver-injury models.

TGF-β, Sca-1, and Mammary Cell Plasticity
2026-09-09
The reference study shows that TGF-β regulates Sca-1 expression while reshaping the plasticity and tumor-initiating potential of pre-neoplastic mammary epithelial cells. Its key contribution is the distinction between endogenous Smad2/3/4-dependent regulation and exogenous TGF-β-driven Sca-1 loss, which appears to use a different mechanism.
