Gene expression is regulated by transcription factors (TFs) and chromatin modifiers such as histone acetyltransferases (HATs). Pessoa Rodrigues et al. revealed the role of the Males absent on the first (MOF) HAT in hematopoietic stem cell (HSC) differentiation into red blood cells. This work raises interesting questions about how MOF controls other hematopoietic differentiation processes.

Disulfiram (DSF), primarily applied in the therapy for alcohol addiction, has been demonstrated to possess the promising capability of anti-tumor in many human cancers, including esophageal squamous cell carcinoma (ESCC). To date, almost all studies about DSF in ESCC are focusing on investigating either drug combinations or nanoparticle-based delivery systems. However, the exact molecular mechanisms mediating the response to DSF in ESCC are totally unknown.

While therapeutic strategies targeting epigenetic dysregulation hold promise for leukemia, epigenetic drugs face several limitations, including low utilization rates, the emergence of resistance, and off-target effects. The hypoxic microenvironment in leukemia further impairs drug sensitivity. Here, we synthesized an MOF-based erythrocyte biomimetic nanoplatform to enhance immune responses against leukemia by targeting three epigenetic modifications.

Lysine acetylation is a conserved post-translational modification involved in energy metabolism in mitochondria and heart function. This study investigates the role of mitochondria-localized lysine acetyltransferase MOF (males absent on the first) in heart failure (HF). We find that MOF is upregulated in mitochondria during HF, and overexpression of mitochondria-targeted MOF (mtMOF) in mouse models results in mitochondria dysfunction, cardiac remodeling, and HF.

Article Synopsis
- L. is a key oilseed crop in Northwest China, and histone acetyltransferases (HATs) are crucial for regulating plant growth and responses to low temperatures.
- Researchers identified 29 genes related to histone acetylation in L. and explored their properties, expression patterns, and relationships, showing these genes significantly impact the crop's cold response.
- Treatment with histone inhibitors, particularly curcumin, improved seed germination and increased protective enzyme activity under low temperatures, highlighting the role of histone modification in L.'s ability to withstand cold stress.

Cyclin-dependent kinase 9 (CDK9), a catalytic subunit of the positive transcription elongation factor b (P-TEFb) complex, is a global transcriptional elongation factor associated with cell proliferation. CDK9 activity is regulated by certain histone acetyltransferases, such as p300, GCN5 and P/CAF. However, the impact of males absent on the first (MOF) (also known as KAT8 or MYST1) on CDK9 activity has not been reported.
