The βTC3 tumor cell line was examined for the presence of functional glucose-dependent insulinotropic polypeptide (GIP) receptors. Increasing amounts of natural porcine GIP decreased the binding of HPLC-purified [125I]GIP to βTC3 cells in a concentration-dependent manner. Displacement of GIP was significant at concentrations as low as 500 pM, and the radioligand was fully displaced at 100 nM. GIP(1–30) produced a displacement of [125I]GIP comparable with that produced by GIP(1–42), and glucagon yielded 20% displacement at a concentration of 1 μM but was without effect at 100 nM. Incubation of βTC3 cells in the presence of glucose concentrations of 2–20 mM yielded a concentration-dependent stimulation of immunoreactive insulin (IRI) release. GIP and glucagon-like peptide-I(7–36) amide (tGLP-I) at concentrations of 1 nM or greater significantly stimulated IRI release in the presence of 2 mM glucose. The threshold glucose concentration for GIP-stimulated IRI release from βTC3 cells was 0.5 mM, and maximal potentiation of IRI release by GIP occurred at 5 mM glucose. Somatostatin significantly inhibited GIP-stimulated IRI release in the presence of 5 mM glucose. It is concluded that βTC3 cells have functional GIP receptors and may provide a useful model for the study of IRI secretion at the cellular level.Key words: insulin, βTC3, glucose-dependent insulinotropic polypeptide.

We used the macrophage-like tumor cell line P388D1 to test whether interleukin-1 (IL-1) stimulate differentiation of osteoclast-like progenitors. Recombinant human interleukin-1 (rhIL-1) alpha inhit ited cell growth in a dose-dependent fashion. Incubation of the cells with rhIL-1 alpha resulted in adherence stimulation of non-specific esterase activity, and increased Fc receptor expression. These results suggest th possibility that IL-1 may be involved in the differentiation of osteoclast progenitors and thus may be an irr portant local factor in the mechanism of bone resorption.

Nanoparticles of alpha ferric oxide ([Formula: see text]-Fe2O3) were prepared by the hydrothermal method. Structural properties of [Formula: see text]-Fe2O3 were determined by XRD, SEM and AFM measurements. The particles had a good matching with standard pattern. Average particle size was about 90[Formula: see text]nm and the distribution extended from about 20[Formula: see text]nm to 120[Formula: see text]nm. Biocompatibility study of ferric oxide nanoparticles against bacteria, parasites, tumor cell line and normal cells was determined. No antibacterial activity was observed for the concentration, of ferric oxide nanoparticles in distilled water, up to 1.5[Formula: see text]mg/ml vs. E. coli and S. aureus. Moreover, MTT assay was used to determine the cytotoxicity against parasites and cells. Intermediate cytotoxicity (53.30%) of 1.5[Formula: see text]mg/ml of prepared nanoparticles was noted against L. tropica, while weak cytotoxicity of 5.20% was observed against L. donovani at the same concentration of ferric oxide nanoparticles. On the other hand, the prepared nanoparticles revealed low cytotoxicity (47.28%) against SR tumor cell line, while no cytotoxicity was shown against lymphocytes, as a model of normal cells.
