1. Both parts consist of ECs that show differential expression of various genes. 2. There is differential expression of the Xenopus homolog of GADD45G in embryonic development. 3. Four gene families are not expanded but shows the same differential expression among castes. 4. These gradients allows for the differential expression of transcription factors. 5. One peculiar expression pattern of CARKD is its differential expression through the development of oligodendrocytes. 6. Differential expression of EpoR between erythroid cells.7. In higher animals including humans, retinoic acid regulates differential expression of Hox genes along the anteroposterior axis. 8. The fate of a rhombomere has been shown to be affected by differential expression of the Hox gene. 9. Although miR-127 and miR-433 have common regulatory elements, they have independent promoters and their differential expression pattern is observed. 10. Differential expression of duplicate gene copies provides a mechanism through which a protein can evolve new functions . [ 3]
