Hyatt BA, Lundberg E, Eye R et al. · microPublication biology · 2025-05 · open access
The ability of transcription factors (TFs) to regulate cell fate decisions is paramount in developmental, homeostatic, and pathogenic contexts. The homeodomain TF NKX2-1 is an essential and evolutionarily conserved master regulator of pulmonary fate in vertebrates. In this study, we tested the…

- Egg Overactivation-An Overlooked Phenomenon of Gamete Physiology.
Tokmakov AA, Sato KI · International journal of molecular sciences · 2025-04 · open access
In many vertebrates, mature ovulated eggs are arrested at metaphase II prior to fertilization. The eggs exit meiotic arrest after fertilization-induced or parthenogenetic activation, followed by embryo development or egg degradation, respectively. Calcium-dependent activation of…

- The Synthesis of GABA during the Tailbud Stage Is Required for Axial Elongation in Xenopus laevis embryos.
Hachiman M, Kuroda H · microPublication biology · 2024-12 · open access
In Xenopus laevis , axial elongation beyond the tailbud stage requires gamma-aminobutyric acid (GABA). However, the role of GABA synthesized during early development in this process remains unclear. In this study, by treating embryos with allylglycine (AG), an inhibitor of GABA synthesis, we…
- An improved method for whole-mount in situ hybridization in regenerating tails of Xenopus laevis tadpoles.
Shitikov AD, Parshina EA, Zaraisky AG et al. · Frontiers in cell and developmental biology · 2024-12 · open access
Whole-mount in situ hybridization (WISH) is a widely used method that supports the concept of "seeing is believing" by enabling the visualization of gene expression patterns in whole-mount multicellular samples or sections. This technique is essential in the study of epimorphic regeneration in…
