1. PROTEÍNAS LIGANTES DOS RECEPTORES DE FATORES DE CRESCIMENTO EM COMPLEXO CUMULUS-OÓCITO BOVINO / GROWTH FACTOR RECEPTOR-BOUND PROTEINS IN BOVINE CUMULUS-OOCYTE COMPLEX
O objetivo do presente trabalho foi caracterizar as proteínas Grb10 e Grb14 em complexos cumulus-oócito (CCOs) de bovinos oriundos de folículos em diferentes fases de desenvolvimento e mostrar o envolvimento do estradiol na regulação da expressão de RNAm. Primeiramente, foram obtidos pool de CCOs de folículos de 3-8mm para verificar a expressão de RN

2. In vitro study of sensitivity to IGF-1 of fibroblasts of children born small for gestational age without postnatal statural recovery / Estudo in vitro da sensibilidade ao IGF-1 de fibroblastos de crianças nascidas pequenas para a idade gestacional sem recuperação estatural pós-natal
Introdução: Crianças nascidas pequenas para a idade gestacional (PIG) apresentam maior risco de permanecerem com baixa estatura na vida adulta. Os fatores de crescimento insulino-símile tipo 1 e 2 (IGF-1 e IGF-2) são os principais fatores endócrinos determinantes do crescimento fetal. A maioria das ações conhecidas do IGF-1 e 2 é mediada via um rece

3. The Adapter Protein ZIP Binds Grb14 and Regulates Its Inhibitory Action on Insulin Signaling by Recruiting Protein Kinase Cζ
Grb14 is a member of the Grb7 family of adapters and acts as a negative regulator of insulin-mediated signaling. Here we found that the protein kinase Cζ (PKCζ) interacting protein, ZIP, interacted with Grb14. Coimmunoprecipitation experiments demonstrated that ZIP bound to both Grb14 and PKCζ, thereby acting as a link in the assembly of a PKCζ-ZIP-Grb14

4. Dual Ablation of Grb10 and Grb14 in Mice Reveals Their Combined Role in Regulation of Insulin Signaling and Glucose Homeostasis
Growth factor receptor bound (Grb)10 and Grb14 are closely related adaptor proteins that bind directly to the insulin receptor (IR) and regulate insulin-induced IR tyrosine phosphorylation and signaling to IRS-1 and Akt. Grb10- and Grb14-deficient mice both exhibit improved whole-body glucose homeostasis as a consequence of enhanced insulin signaling and, in

5. The Grb10/Nedd4 Complex Regulates Ligand-Induced Ubiquitination and Stability of the Insulin-Like Growth Factor I Receptor
The adapter protein Grb10 belongs to a superfamily of related proteins, including Grb7, -10, and -14 and Caenorhabditis elegans Mig10. Grb10 is an interacting partner of the insulin-like growth factor I receptor (IGF-IR) and the insulin receptor (IR). Previous work showed an inhibitory effect of mouse Grb10 (mGrb10α) on IGF-I-mediated mitogenesis (A. Morrio

6. Involvement of Shc in insulin- and epidermal growth factor-induced activation of p21ras.
Shc proteins are phosphorylated on tyrosine residues and associate with growth factor receptor-bound protein 2 (Grb2) upon treatment of cells with epidermal growth factor (EGF) or insulin. We have studied the role of Shc in insulin- and EGF-induced activation of p21ras in NIH 3T3 cells overexpressing human insulin receptors (A14 cells). A14 cells are equally

7. Cas Mediates Transcriptional Activation of the Serum Response Element by Src
The Src substrate p130Cas is a docking protein containing an SH3 domain, a substrate domain that contains multiple consensus SH2 binding sites, and a Src binding region. We have examined the possibility that Cas plays a role in the transcriptional activation of immediate early genes (IEGs) by v-Src. Transcriptional activation of IEGs by v-Src occurs through

8. A Narrow Segment of Maternal Uniparental Disomy of Chromosome 7q31-qter in Silver-Russell Syndrome Delimits a Candidate Gene Region
Maternal uniparental disomy of chromosome 7 (matUPD7), the inheritance of both chromosomes from only the mother, is observed in ∼10% of patients with Silver-Russell syndrome (SRS). It has been suggested that at least one imprinted gene that regulates growth and development resides on human chromosome 7. To date, three imprinted genes—PEG1/MEST, γ2-COP,

9. Identification of six novel autophosphorylation sites on fibroblast growth factor receptor 1 and elucidation of their importance in receptor activation and signal transduction.
Fibroblast growth factor receptor (FGFR) activation leads to receptor autophosphorylation and increased tyrosine phosphorylation of several intra cellular proteins. We have previously shown that autophosphorylated tyrosine 766 in FGFR1 serves as a binding site for one of the SH2 domains of phospholipase Cy and couples FGFR1 to phosphatidylinositol hydrolysis

10. Genome-wide association studies in Alzheimer's disease
Genome-wide association studies (GWAS) have gained considerable momentum over the last couple of years for the identification of novel complex disease genes. In the field of Alzheimer's disease (AD), there are currently eight published and two provisionally reported GWAS, highlighting over two dozen novel potential susceptibility loci beyond the well-establi

11. Molecular cloning of a glibenclamide-sensitive, voltage-gated potassium channel expressed in rabbit kidney.
Shaker genes encode voltage-gated potassium channels (Kv). We have shown previously that genes from Shaker subfamilies Kv1.1, 1.2, 1.4 are expressed in rabbit kidney. Recent functional and molecular evidence indicate that the predominant potassium conductance of the kidney medullary cell line GRB-PAP1 is composed of Shaker-like potassium channels. We now rep

12. Interferons block protein kinase C-dependent but not-independent activation of Raf-1 and mitogen-activated protein kinases and mitogenesis in NIH 3T3 cells.
Interferons (IFNs) exert antiproliferative effects on many types of cells. The underlying molecular mechanism, however, is unclear. One possibility is that IFNs block growth factor-induced mitogenic signaling, which involves activation of Ras/Raf-1/MEK/mitogen-activated protein kinase. We have tested this hypothesis by using HER14 cells (NIH 3T3 cell express
