STAT5b-deficient mice are growth hormone pulse-resistant. Role of STAT5b in sex-specific liver p450 expression.
The signal transducer and transcriptional activator STAT5b is required to maintain the adult male pattern of liver gene expression and whole body pubertal growth rates, as demonstrated by the loss of these growth hormone (GH) pulse-dependent responses in mice with a targeted disruption of the STAT5b gene. The present study investigates whether these phenotypes of STAT5b-deficient mice result fr...
متن کاملCD73-deficient mice are resistant to carcinogenesis.
CD73 is a cell surface 5'-nucleotidase that converts AMP to adenosine, an immune suppressive molecule. CD73 may promote immune escape in cancer by contributing to the degradation of extracellular ATP released by dying cancer cells in hypoxic tumors or following chemotherapy. However, whether CD73 exerts a critical oncogenic function during tumorigenesis is unknown. In this study, we used geneti...
متن کاملGrowth hormone response to growth hormone-releasing peptide-2 in growth hormone-deficient Little mice
OBJECTIVE To investigate a possible direct, growth hormone-releasing, hormone-independent action of a growth hormone secretagogue, GHRP-2, in pituitary somatotroph cells in the presence of inactive growth hormone-releasing hormone receptors. MATERIALS AND METHODS The responses of serum growth hormone to acutely injected growth hormone-releasing P-2 in lit/lit mice, which represent a model of ...
متن کاملMice deficient in the steroid receptor co-activator 1 (SRC-1) are resistant to thyroid hormone.
Steroid receptor co-activator 1 (SRC-1) is a transcription co-factor that enhances the hormone-dependent action, mediated by the thyroid hormone (TH) receptor (TR) and other nuclear receptors. In vitro studies have shown that SRC-1 is necessary for the full expression of TH effect. SRC-1 knockout mice (SRC-1(-/-)) provide a model to examine the role of this co-activator on TH action in vivo. At...
متن کاملSP-D-deficient mice are resistant to hyperoxia.
Surfactant protein D (SP-D), a member of the collectin superfamily, modulates pulmonary inflammatory responses and innate immunity. Disruption of the SP-D gene in mice induces peribronchiolar inflammation, accumulation of large, foamy macrophages, increased bronchoalveolar lavage (BAL) phospholipid, and pulmonary emphysema. We hypothesized that absence of SP-D aggravates hyperoxia-induced injur...
