Impaired ossification in mice lacking the transcription factor Sp3
Sp3 is a ubiquitously expressed member of the Sp family of transcription factors. Recently, the mouse Sp3 gene has been disrupted by homologous recombination. Sp3 null mice die immediately after birth due to respiratory failure. In addition, these mice show a pronounced defect in late tooth formation. Here we show that Sp3 is also required for proper skeletal ossification. Both endochondral and...
متن کاملImpaired hematopoiesis in mice lacking the transcription factor Sp3.
As the zinc-finger transcription factor specificity protein 3 (Sp3) has been implicated in the regulation of many hematopoietic-specific genes, we analyzed the role of Sp3 in hematopoiesis. At embryonic day 18.5 (E18.5), Sp3-/- mice exhibit a partial arrest of T-cell development in the thymus and B-cell numbers are reduced in liver and spleen. However, pre-B-cell proliferation and differentiati...
متن کاملRetinal disease in mice lacking hypoxia-inducible transcription factor-2alpha.
PURPOSE To characterize ocular disease in HIF-2alpha-null mice. METHODS Histologic, electroretinographic (ERG), and molecular studies were performed on samples obtained from age- and gender-matched HIF-2alpha-null (HIF-2alpha-KO), HIF-2alpha-heterozygous (HIF-2alpha-HET), and wild-type (WT) littermate mice. RESULTS HIF-2alpha-KO mice exhibited marked thinning of the retina and abnormal reti...
متن کاملDefect of tyrosine hydroxylase-immunoreactive neurons in the brains of mice lacking the transcription factor Pax6.
In the CNS, the lack of the transcription factor Pax6 has been associated with early defects in cell proliferation, cell specification, and axonal pathfinding of discrete neuronal populations. In this study, we show that Pax6 is expressed in discrete catecholaminergic neuronal populations of the developing ventral thalamus, hypothalamus, and telencephalon. In mice lacking Pax6, these catecholam...
متن کاملImpaired mast cell-driven immune responses in mice lacking the transcription factor NFATc2.
The three calcium-dependent factors NFATc1, c2, and c3 are expressed in cells of the immune system and play pivotal roles in modulating cellular activation. With regard to NFATc2, it was reported that NFATc2-deficient mice display increased immune responses in several models for infection and allergy in vivo. This led to the assumption that NFATc2 is involved in the maintenance of immune homeos...
