Mitoxantrone Targets the ERα DBD–LBD Interface
2026-09-11
Wang and colleagues identify an allosteric binding site between the DNA-binding and ligand-binding domains of estrogen receptor α (ERα), showing that mitoxantrone can disrupt receptor conformation, promote cytoplasmic redistribution, and trigger proteasomal degradation. The work suggests a mechanism for suppressing wild-type and endocrine-resistant ERα mutants that differs from conventional hormone-pocket targeting and from mitoxantrone’s established DNA topoisomerase II inhibitor activity.

Plk1 Control of p31comet in Mitotic Checkpoint Disassembly
2026-09-09
The reference study identifies Polo-like kinase 1 (Plk1) as a direct negative regulator of p31comet–TRIP13-mediated mitotic checkpoint complex disassembly. By mapping the relevant phosphorylation site to S102 and testing an S102A mutant, the work provides a mechanistic explanation for how cells may prevent premature checkpoint silencing during active mitosis.

Melatonin Targets RIPK3 in Atrazine Kidney Injury
2026-09-08
The reference study identifies RIPK3-dependent necroptosis as a central mechanism of atrazine-induced renal tubular injury and shows that melatonin suppresses this pathway. By combining in vivo and in vitro injury models with RIPK3 knockdown and computational structural analysis, the work links melatonin treatment to reduced necroptotic signaling, mitochondrial dysfunction, and inflammation.

2-DG and the Next Frontier of Immunometabolism
2026-09-07
2-Deoxy-D-glucose is more than a glycolysis inhibitor. Used strategically, 2-DG can help translational researchers interrogate how energy stress, tumor-cell fitness, macrophage programming, and antiviral responses intersect. This article connects the metabolic mechanism of 2-DG with findings from the 2024 Immunity study on 25-hydroxycholesterol, AMPK, STAT6, and immunosuppressive tumor-associated macrophages, while providing practical guidance for experimental design and translational interpretation.

Fzd4 N-Glycosylation in Wnt–β-Catenin Signalling
2026-09-05
The reference study identifies Asn59 and Asn144 as conserved N-glycosylation sites on Fzd4 and shows that these modifications support receptor maturation, stability, plasma-membrane trafficking, and signalling. Mutant-rescue experiments in A549 cells and nude-mouse tumour models connect defective Fzd4 glycosylation with reduced non-small cell lung cancer growth and migration, while also highlighting important questions about glycan occupancy and mechanism.
