Description
The study shows butyrate blocks RELA/p65 nuclear translocation to prevent HDAC8 complex formation, but the specific mechanism of this selective inhibition is not explained. Understanding this selectivity is crucial for developing targeted therapeutics that preserve beneficial NF-κB signaling while blocking pathological RELA-HDAC8 interactions.
Gap type: unexplained_observation Source paper: Sodium butyrate ameliorates high glucose-suppressed neuronal mitophagy by restoring PRKN expression via inhibiting the RELA-HDAC8 complex. (2024, Autophagy, PMID:38409852)
