Expression profiles of CTCF and CTCFL in cloudy catshark tissues. Expression levels of cloudy catshark CTCF and CTCFL in adult tissues and embryos at different developmental stages were quantified in TPM (transcripts per kilobase million mapped reads) by the eXpress program using reads mapped to the coding nucleotide sequences of the cloudy catshark (see “Methods” section). Note that the scales are not equal between the genes. Cloudy catshark embryos were staged according to the existing literature35. The details of the RNA-seq data used for the analysis are included in Supplementary Table S2. The equivalent expression profiles of the brownbanded bamboo shark CTCF and CTCFL genes are included in Supplementary Fig. S4.
