Bioinformatic analysis of RBM28 and leptin expression patterns. On the right, RBM28 cDNA was used as bait to screen RNA-seq data from adult male (M) and female (F) red junglefowl [GenBank: ERA252218]. On the left, chicken leptin cDNA [GeneBank: LN794245] was used as the bait sequence. Expression levels were calculated as reads per kilobase per million mapped reads (RPKM). Tissues with above average expression level of at least one of the two genes, RBM28 and leptin (black boxes) were included in the correlation analysis (R = − 0.7)
