Zusammenfassung: | Planarians are an important model for stem cell and regeneration biology, because they can regenerate any missing body structure in a short time. As an important component of ribosomes, ribosomal proteins can synthesize proteins and play a central role in cell cycle checkpoint, cell survival/senescence/apoptosis, and organismal growth and development. In this study, we identified and amplified the homologous gene of RPS3 in Dugesia japonica. Double-stranded RNA mediated RNAi revealed that when the Dj-RPS3 function was lost by planarians; they did not form blastemas and died 100%. Further investigation, confirmed that Dj-RPS3 was involved in regulating the proliferative and early differentiation of neoblasts.
•Losing the Dj-RPS3 function, planarians could not form blastemas and final were dead 100%.•Dj-RPS3 regulated neoblasts' proliferative and early differentiation.•Dj-RPS3 protein remains conservative during evolution. |
