| abstractText | Ndr1 was isolated as a gene upregulated in N-myc mutant mouse embryos and is repressed by N-myc and c-myc. Consistent with Myc regulation, the same gene was also isolated as one sensitive to transformation (Drg1), and in addition as one induced under a few stress conditions (RTP). Two new genes, Ndr2 and Ndr3, were identified which encode proteins highly related to Ndr1/RTP/Drg1 and constitute the Ndr gene family. Ndr2 and Ndr3 are under spatio-temporal regulations distinct from Ndr1, and are not activated in N-myc mutants. When whole embryo RNA was analyzed, Ndr3 expression was already high at 9.5 days postcoitus (dpc), while expression of Ndr2 and Ndr1 became significant after 12.5 dpc and 13. 5 dpc, respectively. At 14.5 dpc, expression of these genes partially overlaps, but many tissues are unique to one of them. For instance, Ndr1 is strongly expressed in the liver and gut epithelium, Ndr2 in the ventricular zone throughout the CNS, and Ndr3 in the spinal cord and the thymus rudiment. Genes of the Ndr family probably have tissue-dependent allotments of the possibly related functions. Copyright 1999 Academic Press. |
