Regulation of cortical neurogenesis by MED13L via transcriptional priming and its implications for MED13L syndrome.

Pathogenic variants in MED13L cause MED13L syndrome, a well-defined neurodevelopmental disorder characterized by motor deficits, intellectual disability, and language delay, yet its underlying developmental and molecular mechanisms remain largely elusive. To address this gap, we generated a gene knockout mouse model of MED13L syndrome. While homozygous Med13l knockout exhibit neonatal lethality accompanied by reduced brain volume and cortical thickness, heterozygous mice are viable and display hallmarks of MED13L syndrome, including impaired learning and memory, reduced motor coordination, and heightened anxiety.

DNA 5mC and RNA mA Collaborate to Upregulate Phosphoenolpyruvate Carboxykinase 2 for Kupffer Cell Activation.

Both DNA 5-methylcytosine (5mC) and RNA N6-methyladenosine (mA) modifications are reported to participate in cellular stress responses including inflammation. Phosphoenolpyruvate carboxykinase 2 (PCK2) is upregulated in Kupffer cells (KCs) to facilitate the proinflammatory phosphorylation signaling cascades upon LPS stimulation, yet the role of 5mC and mA in PCK2 upregulation remain elusive. Here, we report that the significantly augmented PCK2 mRNA and protein levels are associated with global 5mC demethylation coupled with mA hypermethylation in LPS-activated KCs.
