In recent years scientific literature has seen an increase in publications describing new transgenic applications. Although technically-sound, these promising developments might not necessarily translate into products available to the consumer. This article highlights the impact of external factors on the commercial viability of Genetically Modified (GM) animals in the pharmaceutical and food s...

Human granulocyte-macrophage colony-stimulating factor (GM-CSF) stimulates the colony growth of myeloid progenitors in semisolid media, and enhances the function of mature effector cells, including neutrophils, monocytes, and eosinophils. Small cell carcinoma lines (SCCL) have properties of amine precursor uptake and decarboxylation (APUD) cells and express high levels of the enzyme, L-aromatic...

The current study was undertaken to evaluate the effects of granulocyte-macrophage colony-stimulating factor (GM-CSF) and cyclic AMP (cAMP) signaling interaction on human neutrophil apoptosis, either occurring spontaneously or induced by Fas antigen activation. Results show that GM-CSF, dibutyryl cAMP (a cAMP analog) and forskolin (an adenylate cyclase activator) are all able to suppress sponta...

Granulocyte-macrophage colony-stimulating factor (GM-CSF) has been reported to induce antitumor activity in peripheral blood monocytes. We examined the role of GM-CSF on bone marrow (BM) macrophages in inducing antibody-dependent cellular cytotoxicity (ADCC) against murine and human tumor cells in vitro and in vivo with the aim of applying this approach in an autologous bone marrow transplantat...

Little is known about the hormonal effects of puberty on the anatomy of the developing human brain. In a voxel-based morphometry study, sex-related differences in gray matter (GM) volume were examined in 46 subjects aged 8-15 years. Males had larger GM volumes in the left amygdala, whereas females had larger right striatal and bilateral hippocampal GM volumes than males. Sexually dimorphic area...

Infection of asthmatics with human rhinovirus (HRV) enhances airway eosinophilia and airways hyperreactivity. The current studies were performed to further characterize HRV-induced generation by human bronchial epithelial cells of granulocyte macrophage colony-stimulating factor (GM-CSF), a cytokine that could contribute to airway eosinophilia by increasing the survival and activation of eosino...

The present study was mainly focused to analyse the phytochemical, biochemical quantification and mineral profile of dried rose petals Rosa damascena centifolia. Quantitative analysis carbohydrates, protein, phenol qualitative phytochemical were carried out in aqueous ethanolic extract centifolia using standard procedures. From it can be interpreted that preliminary petal showed positive result...

To examine the biologic properties of the molecule encoded by the human gene for granulocyte-macrophage colony-stimulating factor (GM-CSF), we expressed the cloned complementary DNA (cDNA) in transfected monkey COS cells and purified the resultant protein. Purified biosynthetic human GM-CSF was added to cultures of normal hematopoietic progenitor cells in semisolid media, and the resulting colo...

An electrophoretically pure preparation of natural human interleukin-1 (IL-i ) was shown to stimulate in vitro colony formation in human bone marrow cultures. Day 4 myeloid cluster-forming cells (CFC). as well as early (day 7) and late (day 10) granulocyte-macrophage colony-forming units (CFU-GM) were stimulated in a dose-dependent fashion. At optimal concentrations of IL-i . the number of day ...

The effects of human recombinant granulocyte/macrophage colony-stimulating factor (GM-CSF) and human native purified granulocyte colony-stimulating factor (G-CSF) on the growth of clonogenic leukemic blast cells from eight Japanese patients with acute myeloblastic leukemia were studied, using an in vitro leukemic blast colony assay. The results showed that GM-CSF stimulated leukemic blast colon...
