Short peptides isolated from fibrinogen and K-casein have been shown to inhibit platelet aggregation and fibrinogen binding to stimulated platelets. We studied the effects of synthetic peptides occurring in milk proteins (bovine K-casein, KNQDK, and human lactotransferrin, KRDS) and in fibrinogen (RGDS and L10) on subsequent binding of monoclonal antibodies (MoAb) against the glycoprotein (GP) ...

BACKGROUND Kinins participate in the pathophysiology of obesity and type 2 diabetes by mechanisms which are not fully understood. Kinin B(1) receptor knockout mice (B(1) (-/-)) are leaner and exhibit improved insulin sensitivity. METHODOLOGY/PRINCIPAL FINDINGS Here we show that kinin B(1) receptors in adipocytes play a role in controlling whole body insulin action and glucose homeostasis. Adi...

This paper proposes two general active-passive two-way ranging (TWR) methods: AP1-TWR and AP2-TWR. The proposed methods rely on 2 types of anchors: passive-only. first type actively takes part in packet exchange listens to transmissions other anchors, the second only listens. Pairing these concepts with active single-sided (SS), symmetrical double-sided (SDS), alternative (AltDS) TWR provides a...

BACKGROUND The AP2/ERF family includes a large number of developmentally and physiologically important transcription factors sharing an AP2 DNA-binding domain. Among them DREB1/CBF and DREB2 factors are known as master regulators respectively of cold and heat/osmotic stress responses. EXPERIMENTAL APPROACHES The manual annotation of AP2/ERF family from Eucalyptus grandis, Malus, Populus and V...

Establishing preadipocyte cell lines from mature adipose tissues could help lead to a better understanding of adipogenesis. We have established a unique preadipocyte cell line, AP-18, derived from the subepidermal layer of ear skin from an adult C3H/HeM mouse. AP-18 cells exhibit fibroblast-like morphology, slow growth, and contact inhibition. The doubling time of AP-18 cells is 50-60 h, which ...

The coat proteins of clathrin-coated vesicles (CCV) spontaneously self-assemble in vitro, but, in vivo, their self-assembly must be regulated. To determine whether phosphorylation might influence coat formation in the cell, the in vivo phosphorylation state of CCV coat proteins was analyzed. Individual components of the CCV coat were isolated by immunoprecipitation from Madin-Darby bovine kidne...

Transcription factor E3 (TFE3) is a transcription factor that binds to E-box motifs and promotes energy metabolism-related genes. We previously reported that TFE3 directly binds to the insulin receptor substrate-2 promoter in the liver, resulting in increased insulin response. However, the role of TFE3 in other tissues remains unclear. In this study, we generated adipose-specific TFE3 transgeni...

We investigated whether Rad51 overexpression plays a role in soft tissue sarcoma (STS) chemoresistance as well as the regulatory mechanisms underlying its expression. The studies reported here show that Rad51 protein is overexpressed in a large panel of human STS specimens. Human STS cell lines showed increased Rad51 protein expression, as was also observed in nude rat STS xenografts. STS cells...

Sterol regulatory element-binding proteins (SREBPs) are a family of membrane-bound transcription factors that regulate cholesterol and fatty acid homeostasis. In mammals, three SREBP isoforms designated SREBP-1a, SREBP-1c, and SREBP-2 have been identified. SREBP-1a and SREBP-1c are derived from the same gene by virtue of alternatively spliced first exons. SREBP-1a has a longer transcriptional a...
