ABSTRACT
OBJECTIVE@# To observe the expression of gene in the early development stage of wild zebrafish embryos.@*METHODS@# The collinearity of gene and the sequence similarity of G6pd protein were analyzed with gene database and BLAST software, respectively. Expression of gene in different development stages of zebrafish embryos was detected by hybridization. The -EGFP-pCS recombinant plasmids were microinjected into zebrafish embryos, and fluorescence was observed under a fluorescence microscope. The expression of G6pd protein at 24, 48 and 72 hour post fertilization (hpf) zebrafish embryos was detected by Western blotting; the enzyme activity of G6pd at 24, 48 and 72 hpf zebrafish embryos was detected by modified G6pd quantitative ratio method.@*RESULTS@# The G6pd protein similarity of zebrafish and human was 88%, and that of zebrafish and mouse was 87%. The results of hybridization showed that the gene was mainly expressed in the hematopoietic tissues of zebrafish; the results observed after microinjection of -EGFP-pCS recombinant plasmid were consistent with the results of hybridization. At 24, 48 and 72 hpf, the relative expression levels of G6pd protein in zebrafish embryos were 1.44±0.03, 1.47±0.05, and 1.54±0.02, respectively(>0.05); the G6pd enzyme activity levels were 1.74±0.17, 1.75±0.12, 1.71±0.22, respectively (>0.05).@*CONCLUSIONS@# The study has observed the expression of gene and G6pd protein, and G6pd enzyme activity in zebrafish embryos at different development phases, which provides a reference for the establishment of a zebrafish G6PD deficiency model.
