In order to study the consequences of the loss of Icsbp expression in hematopoiesis Granulocyte-Monocyte Progenitors from bone marrow were isolated from Icsbp wild type and deficient mice by flow cytometry. Global gene expression was performed using Affymetrix gene chip technology.

View SamplesThe activity of different E2F constructs with respect to gene expression was measured. E2F constructs differed in degradability, and were doxycycline inducible. Different samples with the different E2F constructs, and with or without dox inductions were assayed for gene expression.

View SamplesWe have investigated the p53-dependent stress response in medium spiny neurons (MSNs) that degenerate in Huntingtons disease. To induce p53 signaling cascade, we have genetically inactivated by the Cre/loxP system the essential RNA polymerase I (Pol I) transcription factor TIF-IA, leading to stabilization of p53 and induction of p53-dependent apoptosis.
A neuroprotective phase precedes striatal degeneration upon nucleolar stress.

Sympathetic alpha(2)-adrenoceptors prevent cardiac hypertrophy and fibrosis in mice at baseline but not after chronic pressure overload.

Chronic cardiac pressure overload induces adrenal medulla hypertrophy and increased catecholamine synthesis.

View Samplesalpha2-adrenoceptors are essential presynaptic regulators of norepinephrine release from sympathetic nerves. Previous studies in mice with targeted deletions in the three alpha2-adrenoceptor genes have indicated that these receptors are essential for embryonic development. In the present study, we searched for the alpha2-adrenoceptor subtype(s) involved in placental development and its molecular mechanism using mice carrying targeted deletions in alpha2-adrenoceptor genes.
Upregulation of soluble vascular endothelial growth factor receptor 1 contributes to angiogenesis defects in the placenta of alpha 2B-adrenoceptor deficient mice.

View SamplesThe goal of this study was to determine the role of the X-linked epigenetic mediator, O-linked N-acetylglucosamine transferase (OGT) in establishment of trophoblast-specific sex differences in gene expression and to determine if sex differences in OGT and downstream epigenetic modifications contribute to sex differences in hypothalamic gene expression and development.
