Novel calmodulin inhibitors reduce p53 activity in models of diamond-blackfan anemia, suggesting potential for better therapies.

This research aims to identify effective calmodulin modulators to correct p53 related defects in Diamond-Blackfan Anemia.
Utilized zebrafish models and human HSPC models for drug testing.
Implemented CRISPR-Cas9 editing to induce ribosomal mutations in target cells.
Monitored p53 activity via CDKN1A/p21 expression levels.
Compared effects of the new compounds FTX-1 and FTX-2 against trifluoperazine.
FTX-1 and FTX-2 significantly reduced p53 activity at lower concentrations compared to trifluoperazine.
Improved hemoglobin levels and erythroid development were observed in zebrafish models of DBA.
FTX-2 showed excellent efficacy in human HSPC models with marked differences against controls.

Corry et al. (2025) studied this question.
