Description
To understand the relationship between RNA localization and translation, it is necessary to visualize the movement of the RNA in real time. In his second lecture, Singer explains how his lab found an ingenious way to label RNAs in live cells and follow their movement. In the nucleus, RNA moves by diffusion and stochastically finds a nuclear pore to exit. In the cytoplasm, however, it is a different story. RNA, in a translationally repressed state, undergoes directed movement along the cytoskeleton. Once it reaches its destination, translation is activated. Singer’s lab showed that neuronal stimulation leads to ß-actin mRNA localization to dendritic spines, followed by translation, and stabilization of the synapse; events that are crucial for memory and learning.

Jan-Michael Peters Part 2: How do Cohesin and CTCF Fold DNA in Mammalian Genomes?: In his second talk, Peters presents evidence that cohesin is indeed necessary for genomic DNA to fold into loops. Long range DNA interactions such as loops can be detected using a technique called Hi-C. Using Hi-C, by iBiology Podcast
