The Impact of Early Genes and Gene Editing Technology Associated with Clustered Repeats on the Development of Human Body Organs

Early growth response 1 (EGR-1) and homeobox (Hox) proteins play crucial roles in regulating genes within the body, promoting cell renewal, and expediting the wound healing process. Conversely, Clustered Regularly Interspaced Palindromic Re-peats/Associated (CRISPR-Cas) technology is primarily involved in gene editing. However, significant gaps persist in understanding the mechanisms of key genes like EGR-1, CRISPR/Cas, and HOX genes in organ development. Unveiling their mechanisms is crucial for advancing organ development and discovering new therapeutic strategies. This study aims to investigate the roles of EGR-1, CRISPR/Cas, and HOX genes in organ development and growth. The study used CRISPR/Cas to investigate the impact of catalase mutations on organ regeneration. Early embryonic mutants were generated by injecting gRNAs and Cas9 protein into zygotes, followed by tail amputation in larvae. Additionally, the study explored the role of specific Hox genes in axon elongation and Wnt signaling regulation. EGR-1, induced by TGF-β1, enhanced collagen production, underscoring its importance in wound healing. Integration of EGR-1, HOX proteins, and CRISPR-Cas revealed a regulatory complex influencing organ development. The integration of EGR-1, HOX proteins, and CRISPR-Cas revealed a regulatory complex. EGR-1 aids wound healing, HOX proteins influence fetal development and organ formation, and CRISPR-Cas enables precise genome modifications.
