Using in vivo imaging to measure RNA mobility in Xenopus laevis oocytes
چکیده انگلیسی
RNA localization in the Xenopus oocyte is responsible for the establishment of polarity during oogenesis as well as the specification of germ layers during embryogenesis. However, the inability to monitor mRNA localization in live vertebrate oocytes has posed a major barrier to understanding the mechanisms driving directional transport. Here we describe a method for imaging MS2 tagged RNA in live Xenopus oocytes to study the dynamics of RNA localization. We also focus on methods for implementing and analyzing FRAP data. This protocol is optimized for imaging of the RNAs in stage II oocytes but it can be adapted to study dynamics of other molecules during oogenesis. Using this approach, mobility can be measured in different regions of the oocyte, enabling the direct observation of molecular dynamics throughout the oocyte.
