Abstract
Recent research has revealed that the maternal non-coding RNA genes (Gtl2, Rian and Mirg) from the Dlk1-Dio3 imprinted cluster are closely related to the full development potential of the induced pluripotent stem cells (iPSCs). Transcriptional silencing of these genes failed to generate all-iPSC mice, indicating their significant contribution to embryogenesis. However, except for Gtl2, little information regarding these genes has been acquired in this cluster. In the present study, we analyzed the spatiotemporal expression patterns of Mirg during mouse embryogenesis. Using in situ hybridization and quantitative PCR, we demonstrated that Mirg non-coding RNA exhibited sustained expression throughout mouse embryogenesis from E8.5 to E18.5. Strong expression was detected in the central nervous system (E9.5–E15.5) and various skeletal muscles (E13.5 and E15.5), and the subcellular localization appeared to be in the nuclei. The pituitary and adrenal gland also showed high expression of Mirg, but, unlike the skeletal muscles and the neural circuitry, the signals were not concentrated in the nuclei. In the major internal organs, Mirg maintained low expression during embryogenesis (E12.5–E18.5) whereas in the liver and the developing lung, Mirg was expressed with a gradually decreasing trend and a gradually raising trend, respectively. These findings indicate that temporal regulation of Mirg expression may be required during specific stages and in specific tissues during embryonic development.
