In this report we have investigated the role of the Ets-1 transcription factor in the differentiation of the NK cell lineage in mice. Splenic NK cells express high levels of Ets-1. Ets-1-deficient mice produced by gene targeting developed mature erythrocytes, monocytes, neutrophils, and T and B lymphocytes. However, spleens from the Ets-1-deficient mice(More)
Genes that control the early stages of adipogenesis remain largely unknown. Here, we show that murine GATA-2 and GATA-3 are specifically expressed in white adipocyte precursors and that their down-regulation sets the stage for terminal differentiation. Constitutive GATA-2 and GATA-3 expression suppressed adipocyte differentiation and trapped cells at the(More)
The transcription factor GATA-3 is expressed at every stage of thymic development, but its role in thymocyte differentiation is unknown. The fact that RAG chimeric animals lacking GATA-3 cannot generate early thymocytes from common lymphoid progenitors has thus far precluded investigation of the function of GATA-3 in the thymus. To address this, we(More)
THE zinc-finger transcription factor GATA-3 is expressed in haematopoietic cells and in the developing kidney and nervous system. Within the haematopoietic lineages, expression of GATA-3 is restricted to thymocytes and T cells. Functionally important GATA-3 binding sites have been identified in multiple T-cell-specific genes. Mice containing homozygous null(More)
The human salivary amylase genes are associated with two inserted elements, a gamma-actin-processed pseudogene and an endogenous retroviral-like element. To test the contribution of these inserted elements to tissue specificity, 25 lines of transgenic mice carrying 10 amylase constructs were established. A 1-kb fragment of AMY1C (-1003 to +2) was found to(More)
The unique contractile phenotype of cardiac myocytes is determined by the expression of a set of cardiac muscle-specific genes. By analogy to other mammalian developmental systems, it is likely that the coordinate expression of cardiac genes is controlled by lineage-specific transcription factors that interact with promoter and enhancer elements in the(More)
A dominant mutation was generated in transgenic mice as a consequence of insertional mutation. Heterozygous mice from transgenic line 9257 (Tg9257) are hyperactive with bidirectional circling behavior and have a distinctive facial appearance due to hypoplasia of the nasal bone. Morphological analysis of the inner ear revealed asymmetric abnormalities of the(More)
The human PCK1 gene encoding phosphoenolpyruvate carboxykinase (GTP) (PEPCK) was isolated and sequenced. There is 91% amino acid sequence identity (567/622 residues) between the human and the rat proteins, with conservation of intron/exon borders. A polymorphic dinucleotide microsatellite with the structure (CA)16(TA)5(CA) was identified in the 3'(More)
Analysis of the structures of the human amylase genes has demonstrated that this multigene family contains at least five tandem gene copies, closely related in sequence but with distinct tissue specific expression. The structures of the genes demonstrate that the human salivary amylase gene was derived from a preexisting pancreatic amylase gene. Insertion(More)
Expression of an amylase/CAT hybrid gene was analyzed in transgenic mice. The amylase promoter was derived from a pancreatic amylase gene whose expression is repressed in diabetic animals. Pancreas-specific expression of the amylase/chloramphenicol acetyl-transferase (CAT) construct was observed in two independent transgenic lines. Correct initiation of(More)
