SP2509 and the Next Logic of Cancer Epigenetics
2026-08-24
SP2509 is more than a potent LSD1 probe: it offers translational researchers a way to connect histone demethylation, AML cell-state control, and combination-oriented cancer epigenetics. This thought-leadership analysis examines how selective LSD1 antagonism can be evaluated alongside broader chromatin and oncogenic circuits, while separating established evidence from forward-looking hypotheses. It also provides practical guidance for designing reproducible AML viability, apoptosis, differentiation, and target-engagement studies.

FDXR Disease, Ferroptosis, and NRF2 Signaling
2026-08-23
A 2025 Cell Death Discovery study identifies ferroptosis, driven by mitochondrial and plasma-membrane lipid peroxidation, as a pathogenic mechanism in FDXR-related disease. Its mouse-model data connect FDXR loss of function to disrupted NRF2–SLC7A11 antioxidant signaling and show that NRF2 activation with omaveloxolone can mitigate disease-associated pathology.
