However, recent studies suggest that some of these factors may also be expressed and function outside the germline. One such example includes Vasa, a DEAD-box RNA helicase that appears to control localized translation on the spindle, facilitating efficient protein synthesis during embryogenesis of the sea urchin. However, it remains unclear if other germline factors are also involved in this process. In this study, we investigated the localization dynamics of Vasa's partners in the germline, such as Tudor-domain-containing proteins (TDRDs) and P-element-induced wimpy testis proteins (Piwis). Among TDRDs tested in this study, we found that TDRD7 is enriched on the spindle and forms granules with Vasa during early embryogenesis. Vasa and TDRD7 recruited each other when the expression of either was forced at the membrane, suggesting their interaction with each other. TDRD7 mutants lacking the N-terminal eLOTUS domain or the central intrinsically disordered region exhibited reduced granule formation, which also compromised their recruitment to Vasa. In contrast, PiwiL1/2 and PiwiL3 showed enrichment at the perinuclear region and the spindle, yet were never recruited to Vasa or TDRD7 when either was expressed at the membrane. These results suggest that a group of germline factors is present and may dynamically interact with each other on the spindle, contributing to somatic cell regulation in the sea urchin embryo.</div></div>","PeriodicalId":11070,"journal":{"name":"Developmental biology","volume":"527 ","pages":"Pages 98-108"},"PeriodicalIF":2.1,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144759390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of PRDM13 in PTF1A + cerebellar progenitors suggests a similar role for PRDM13 in cerebellar neuronal specification.

Despite their demonstrated utility in fields such as diagnostics, synthetic biology and environmental science, the application of RNA biosensors in developmental biology has only begun to emerge within the past decade. This gap is notable given the potential of these tools to address key questions about spatiotemporal RNA regulation and cellular signaling during development. This perspective review presents a selection of RNA biosensors, including fluorescent RNA aptamers, CRISPR-Cas-based systems, riboswitches, and catalytic RNA sensors, which have gained attraction in other scientific disciplines. These tools can be used not only to study intrinsic RNA biology, such as RNA expression, splicing, and localization, but also to detect the effects of extrinsic physical and chemical factors, including pH, temperature, redox state, and mechanical stress, on RNA behavior during developmental processes. These examples illustrate how RNA biosensors could be adapted to study developmental mechanisms in model organisms, enabling investigations into RNA dynamics and their role in shaping developmental processes.

Interestingly, <em>Cyclin Dependent Kinase 1</em> (<em>CDK1</em>), <em>Polo Like Kinase 1</em> (<em>PLK1</em>), and <em>Aurora kinase</em> (<em>Aurk</em>) transcripts are expressed by endomesodermal cells of the blastula, the multipotent stem cells in coelomic pouches and/or the skeletogenic mesoderm of the gastrula that are not actively dividing. To further test that proteins important for mitosis may perform additional functions during embryogenesis, we treated embryos with CDK1, PLK1, and Aurk inhibitors, which resulted in a dose-dependent developmental arrest or delay and defects in gastrulation, skeletogenesis, and epithelial to mesenchymal transition. Further analysis indicates that the number of mesodermally-derived pigment cells is significantly less in CDK1 and PLK1 inhibited embryos and significantly increased in Aurk inhibited embryos. Importantly, the percentage of pigment cells undergoing cell proliferation in drug-treated embryos was not different than the control, indicating additional functions of CDK1, PLK1, and Aurk.

During embryonic development, nephron formation relies on repetitive interactions between nephron progenitor cells (NPCs) and surrounding epithelial and stromal tissue, a process tightly regulated by genetic factors. NPCs are crucial to kidney development due to their self-renewal and multipotent abilities. Rac1 is a small GTPase and its mutation is implicated in multiple events of development and disease. While aberrant Rac1 activity has been linked to various kidney diseases, its role in NPCs remains unclear. In this study, we generated tissue-specific Rac1 knockout models in NPCs. Our data demonstrate that Rac1 deficiency disrupts cell cycle progression and reduces cell proliferation rates. Consequently, Rac1 conditional knockout kidneys exhibit fewer NPCs and nascent nephrons, resulting in a hypoplastic phenotype. Using qPCR and immunostaining, we further show that JNK signaling activity is downregulated in both Rac1-deficient NPCs and in vivo models. Conversely, expression of an autoactivated form of Rac1 (Rac1<sup>G12V</sup>) in NPCs increases NPC numbers per ureteric bud and enhances cell proliferation, accompanied by upregulated JNK signaling. We conclude that Rac1 plays a critical role in maintaining NPC proliferation and self-renewal, likely through the JNK signaling pathway.</div></div>","PeriodicalId":11070,"journal":{"name":"Developmental biology","volume":"526 ","pages":"Pages 147-158"},"PeriodicalIF":2.5,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
