Fig. 4

Amplified regions of the predicted promoter sequences relative to the transcription start site. Numbers with a plus or minus sign show CpG positions relative to the transcription start site. The yellow boxes represent CpG dinucleotide sites in the target gene promoter. a Three CpG sites in the Sox9a gene promoters of 2nRCC and 4nRCC are marked with yellow boxes. b Seven CpG sites in the Amh gene promoter of 2nRCC are marked with yellow boxes, whereas only four CpG sites are present in the 4nRCC promoter. c Ten CpG sites in the Cyp19a1a gene promoter of 2nRCC are marked with yellow boxes, and nine CpG sites in the promoter of 4nRCC are marked. The last CpG site in both 4nRCC and 2nRCC was not included due to the primer position
