An improved genetic algorithm (IGA) is proposed to achieve S-system gene network modeling of Xenopus frog egg. Via the time-courses training datasets from Michaelis-Menten model, the optimal parameters are learned. The S-system can clearly describe activative and inhibitory interaction between genes as generating and consuming process. We concern the mitotic control in cell-cycle of Xenopus frog egg to realize cyclin-Cdc2 and Cdc25 for MPF activity. The proposed IGA can achieve global search with migration and keep the best chromosome with elitism operation. The generated gene regulatory networks can provide biological researchers for further experiments in Xenopus frog egg cell cycle control.

Whole-mount 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 cold-blooded vertebrates, where complex three-dimensional organs such as tails, limbs, and eyes are completely restored after loss. The tadpoles of the frog serve as a convenient model for studying regeneration, as they can regenerate their tails within a week after amputation.

Mammals suffer permanent hearing impairment from the loss of auditory hair cells due to their inability to regenerate. In contrast, lower vertebrates exhibit extraordinary capacity for hair cell regeneration and hearing restoration, but the mechanisms remain unclear. Here we characterize the single-cell atlas of Xenopus laevis inner ear and perform a comprehensive comparison with mouse model.

Various DNA damage checkpoint control mechanisms in eukaryotic cells help maintain genomic integrity. Among these, NBS1, a key component of the MRE11-RAD50-NBS1 (MRN) complex, is an essential protein involved in the DNA damage response (DDR). In this study, we discovered that DNA damage-binding protein 1 (DDB1) interacts with NBS1.
