With the completion of large-scale genome sequencing of human beings and other organisms, understanding the expression of control elements on the genome has become an important research task in the post-genome era. The enhancer trapping technology is an effective method for identifying enhancer elements in the genome and understanding its mechanism for gene expression regulation. In this study, we selected the stable enhancer trapping line TK4 (head and trunk specific GFP expression), which is generated with the mediation of Tol2 transposon system, and analyzed the trapped enhancers with the techniques of Splinkerette PCR (sp-PCR), in situ hybridization and comparative genomics. We crossed F1 individuals of TK4 line with wild-type zebrafish, collected fertilized eggs, and then detected the expression pattern of green fluorescent protein reporter gene by fluorescence microscopy at six different developmental stages, 6 hpf (hour post fertilization), 24 hpf, 48 hpf, 3 dpf (day post fertilization), 4 dpf and 5 dpf . The zebrafish genome flank sequence near the insertion site of Tol2 transposon was cloned by sp-PCR, and the results revealed that the insertion located at the position 27749253 of chromosome 23, and the transgene inserted reversely inside the intron 1 of rps26 gene. Within the 100 kb region of the insertion site, totally, seven genes including arf3a, wnt10b, wnt1, rps26, IKZF4, dnajc22 and lmbr1l were identified. Comparative genomic analysis by VISTA program revealed that there were two potential enhancer elements in the downstream of rps26 gene, which were conserved non-coding sequence (CNS) 1 and CNS2. The results of in situ hybridization showed that two transcripts of rps26 gene were maternal expression, the expression of rps26-201 in zygote was earlier than that of rps26-001, and the GFP signal of TK4 line zebrafish was not detectable before 6hpf, the expression patterns of rps26 and GFP at the late stages display similarity, and also represent differences, which suggested that the expression of rps26 and GFP may be controlled by the same enhancer, and also by the different enhancer, and two potential enhancers (CNS1 and CNS2) may play a differential regulation roles on the spatial and temporal expression of nearby genes (including rps26). In this study, we successfully obtained two potential enhancers near rps26 gene for the first time, which laid a foundation for further study of the regulation mechanism between these two enhancers and nearby genes in the genome, and the combination technique used in this study also provides a reference for enhancer analysis.
