In this episode of the Epigenetics Podcast, we talked with Tanja Vogel from the University Clinics Freiburg about her work on epigenetic modifications in stem cells during central nervous system development.
During our discussion, Dr. Vogel shared that she and her team have investigated H3K79 methylation and its functional significance, which remains a topic of debate in the scientific community. They’ve also investigated the role of DOT1L in neural development and its implications for neuronal networks, as disrupting DOT1L can lead to conditions such as epilepsy and schizophrenia. They explored the function of the SOX2 enhancer in the presence or absence of DOT1L enzymatic inhibition.
The conversation then shifts to FoxG1, a vital player in forebrain development. The team uncovered its role in chromatin accessibility and its connection to microRNA processing. Their study, utilizing ChIP-Seq, reveals FoxG1's interactions with enhancer regions and other transcription factors, like NeuroD1.
