Constitutive activities of the bovine SIX1 haplotypes in QCMCs. The relative lucferase of the transcriptional activities in the candidate haplotypes was used to normalize the promoter activity. Haplotypes of the proximal minimal promoter region of the SIX1 gene were transfected into the QCMCs, and pGL3-Basic served as a control. The cells were collected for the luciferase assay at 48 h. The results are expressed as the mean ± standard deviation in arbitrary units based on the firefly luciferase activity normalized to the renilla luciferase activity in triplicate transfections. The unpaired Student’s t-test was used to detect significant differences. “*”P < 0.05 and “**”P < 0.01.
