5-Aza-2'-Deoxycytidine Toxicology in Mice
2026-09-15
Momparler and Frith established a route-relevant mouse toxicology framework for 5-Aza-2'-deoxycytidine by combining continuous intravenous infusion, sex-specific LD50 estimation, hematologic monitoring, and histopathology. The study identified reversible injury to proliferative tissues, while persistent leukopenia highlighted the need to separate epigenetic or antileukemic activity from delayed marrow toxicity.

APEX2, TERT Expression, and Stem Cell DNA Repair
2026-09-13
A 2024 bioRxiv study identifies APEX2 as a previously unrecognized regulator of efficient TERT expression in human embryonic stem cells, distinct from its paralog APEX1. By combining APEX2 knockdown, RNA sequencing, telomerase assays, and chromatin immunoprecipitation, the work connects DNA repair at repetitive elements with telomerase regulation and stem-cell biology.

Deferasirox, Mitochondrial ROS, and Myeloid Maturation
2026-09-12
The reference study shows that deferasirox affects myeloid differentiation in a maturation- and oxygen-dependent manner by altering mitochondrial reactive oxygen species and NF-κB-related transcriptional programs. Its combination of murine and human models, hypoxia experiments, and single-cell transcriptomics clarifies why deferasirox can produce distinct effects in progenitors and neutrophils, while also defining important limits for translating these findings into iron overload treatment research.

TRAP-1 Reactivates p53Y220C Through Proximity
2026-09-11
The preprint Activating p53Y220C with a Mutant-Specific Small Molecule describes TRAP-1, a chemical inducer of proximity that brings mutant p53 and BRD4 together to restore p53-dependent transcription. In p53Y220C-expressing pancreatic cell lines, this mechanism increased p21 and other target genes while suppressing cell growth, providing a proof of concept for proximity-based reactivation of mutant tumor suppressors.
