Abstract: Objective To determine the transcription initiation site of mouse Prss37 gene, and verify the tissue specificity of the promoter in vivo using transgenic technology. Methods The transcription initiation site was identified by 5' rapid amplification of cDNA ends (5' RACE ) used to analyze the mRNA of testis from C57BL/6J mice . The plasmids including different lengths of promoter (1kb, 4kb, and 6kb) and luciferase gene were constructed. Then, these plasmids were injected into male pronucleus by microinjection technique to obtain luciferase positive transgenic mice. Results The transcription start site of Prss37 gene was located at the 40bp site upstream of the predicted site reported in GeneBankTM (NM_026317.2). Moreover, three kinds of transgenic mice were successfully established, but the expression of luciferase gene was only detectable in transgenic mice driven by 1kb promoter. The higher expression level of luciferase was found in brain, testis and epididymis tissues. Conclusion The transgenic mice expressing luciferase in testis and epididymis tissues were successfully established, which laid a foundation for further research on the transcriptional regulation of Prss37 gene.
