| Popis: | Because of its critical role in the control of cell proliferation and differentiation, we postulated that E2F-1 could have a role in murine development. To this end, the organ and developmental expression of the E2F-1 transcription factor was analyzed from mid-gestation to late-stage embryogenesis. We demonstrate that the mRNA levels for E2F-1 and its heterodimeric partner DP-1 reach maximal levels in the late embryonic and early postnatal period but decline in the later postnatal and adult periods. Additionally, using high resolution in situ hybridization, high expression of E2F-1 was observed in specific cells of individual tissues, suggesting that the role of E2F-1 may be more complex than previously indicated from cell culture studies. Furthermore, the unusual pattern of E2F-1 and DP-1 developmental expression may have an essential role in certain cells and tissues in the late embryonic and early postnatal period. |
