b"In this episode of the Epigenetics Podcast, we caught up with Luca Giorgetti from the Friedrich Miescher Institute to hear about his work on long-range transcriptional control by 3D chromosome structure.\\nLuca Giorgetti's research focuses on chromosomal interactions, transcriptional output, and the dynamics of enhancer-promoter relationships. His lab investigated the causal relationship between chromosome interactions and transcriptional events. They\\u2019ve found that by manipulating the contact probabilities between an enhancer and a promoter by changing their distance, these changes had a substantial effect on transcription levels. This project was an experiment that Luca Giorgetti was eager to do, and it allowed him to establish a smooth functional relationship between contact probabilities and changes in transcription levels.\\n\\xa0\\nReferences\\n\\nGiorgetti, L., Galupa, R., Nora, E.
