Murine 3T3-L1 preadipocytes proliferate normally in medium containing fetal calf serum depleted of insulin, growth hormone, and insulin-like growth factor-I (IGF-I). However, the cells do not differentiate into adipocytes in the presence of the hormone-depleted serum. Supplementation of the growth medium with 10-20 nM IGF-I or 2 microM insulin restores the(More)
PURPOSE To investigate the correlation between enhancement patterns and parameters of contrast material-enhanced ultrasonography (US) with prognostic factors in breast cancers. MATERIALS AND METHODS The study was approved by the institutional ethics committee, and written informed consent was obtained. Surgical resection specimens of 74 malignant breast(More)
The biogenesis, intracellular transport, and functional properties of the insulin proreceptor and modified insulin receptors were studied in hormone-responsive 3T3-L1 adipocytes. After control cells were labeled with [35S]Met for 7 min, the principal polypeptide that was precipitated by anti-insulin receptor antibodies had a molecular weight (Mr) of 180(More)
This study was conducted to investigate the effects of aescin treatment in a rodent model treated with an experimentally induced varicocele. Experimental varicocele was induced by partial ligation of the left renal vein of rats. Aescin administration was performed daily for 4 weeks after the varicocele induction. Seven weeks later, a contrast-enhanced(More)
Cell surface and cryptic insulin receptors were solubilized from the particulate fraction of murine 3T3-L1 adipocytes with buffer containing 1% Triton X-100. Solubilized receptors were affinity crosslinked with 125I-labeled insulin and disuccinimidyl suberate and characterized by sodium dodecyl sulfate/polyacrylamide gel electrophoresis and autoradiography(More)
