Am. J. Endocrinol. Metab. 288, E731-E740. Expression and secretion of inflammation-related adipokines by human adipocytes differentiated in culture: integrated response to TNFα. 2005

Wang, B., Jenkins, J.R., and Trayhurn, P.

Notes: In this study, the expression of various adipokine genes linked to inflammation was examined during differentiation of pre-adipocytes to adipocytes in primary culture. The effect of TNFα on expression of these adipokines in differentiated human adipocytes was also investigated. qPCR was used to measure expression levels of the various adipokines, including NGF, during development and upon TNFα exposure. In addition, secretion of adipokines into the culture media was measured by ELISA, the NGF Emax® ImmunoAssay System being used to determine NGF levels. (3502)

Proc. Natl. Acad. Sci. USA 102, 18171-18176. Human stem/progenitor cells from bone marrow promote neurogenesis of endogenous neural stem cells in the hippocampus of mice. 2005

Munoz, J.R., Stoutenger, B.R., Robinson, A.P., Spees, J.L. and Prockrop, D.J.

Notes: In this study, implantation of human bone marrow stem/progenitor cells (MSCs) into the hippocampus of immunodeficient mice was found to stimulate proliferation, migration and differentiation of endogenous neural stem cells. Results of immunohistochemical analyses were confirmed by ELISA. The NGF Emax® Immunoassay System was used to determine NGF levels in isolated hippocampi at various intervals after implantation of the MSCs. (3500)

Ann. Oncol. 15, 1439–42. Early predictors of peripheral neurotoxicity in cisplatin and paclitaxel combination chemotherapy. 2004

Cavaletti, G., Bogliun, G., Marzorati, L., Zincone, A., Piatti, M., Colombo, N., Franchi, D., La Presa, M.T., Lissoni, A., Buda, A., Fei, F., Cundari, S. and Zanna, C.

Notes: Patients with locally advanced squamous cervical carcinoma were monitored for chemotherapy-induced peripheral neurotoxicity (CIPN). Plasma drawn from the study participants was stored at –80°C prior to testing for nerve growth factor (NGF)levels using the NGF Emax® ImmunoAssay System. The authors note that a highly significant correlation existed between a decrease in circulating levels of NGF and an increase in the severity of CIPN. (3338)

J. Neurosci. 24, 10542-10552. RACK1 and brain-derived neurotrophic factor: a homeostatic pathway that regulates alcohol addiction. 2004

McGough, N.N., He, D.Y., Logrip, M.L., Jeanblanc, J., Phamluong, K., Luong, K., Kharazia, V., Janak, P.H. and Ron D.

Notes: The authors examine the role of brain-derived neurotrophic factor (BDNF) in alcohol addition. RNA was isolated from primary rat hippocampal neurons cultured in the absence or presence of ethanol. The RNA was reverse transcribed using the Reverse Transcription System, and BDNF and GPDH RNAs were quantitated by fluorescent real-time PCR. BDNF and nerve growth factor (NGF) protein levels were monitored using the BNDF and NGF Emax® ImmunoAssay Systems. (3441)

Development 131, 1175–86. Target-derived BMP signaling limits sensory neuron number and the extent of peripheral innervation in vivo. 2004

Guha, U., Gomes, W.A., Samanta, J., Gupta, M., Rice, F.L. and Kessler, J.A.

Notes: To study the role of bone morphogenetic protein (BMP) in the development of peripheral sensory neurons, transgenic mice were created that overexpressed either a BMP inhibitor, noggin, or a ligand, BMP4. To determine if the increased trigeminal innervation and neuron numbers seen in these mice were due to increased neurotrophin levels, the mystacial (whisker) pads of 3-day-old mice were tested for the presence of NGF, BDNF and NT-3 using each of the corresponding Emax® ImmunoAssay Systems. The results indicated there were no significant changes in neurotrophin levels except for a decrease in NT-3 in the noggin transgenic mice. (3337)

Biol. Reprod. 68, 2038-2043. Chronic intermittent cold stress activates ovarian sympathetic nerves and modifies ovarian follicular development in the rat. 2003

Dorfman, M., Arancibia, S., Fiedler, J.L. and Lara, H.E.

Notes: The authors studied the effects of a chronic intermittent cold stress regime on sympathetic nerve activation and ovarian physiology. To analyze whether this effect on noradrenaline was preceded by activation of the neurotrophic factor system responsible for growth and survival of sympathetic neurons, they measured nerve growth factor in adult female Sprague-Dawley rats using the NGF Emax® ImmunoAssay System.

Brain Res. Mol. Brain Res. 88, 203-213. Cultured olfactory ensheathing cells express nerve growth factor, brain-derived neurotrophic factor, glia cell line-derived neurotrophic factor and their receptors. 2001

Woodhall E., West A.K., and Chuah M.I..

Notes: Transplantation of olfactory ensheathing cells into lesions in the central nervous system is able to stimulate the growth of axons and in some cases restore functional connections. To investigate the mechanism, the authors quantitated the production of growth factors and expression of corresponding receptors by rat olfactory ensheathing cells. Levels of brain-derived neurotrophic factor, glial-cell-derived neurotrophic factor, nerve growth factor, and neurotrophin-3 were monitored using Promega's BDNF Emax® ImmunoAssay System, GDNF Emax® ImmunoAssay System, NGF Emax® ImmunoAssay System, and NT-3 Emax® ImmunoAssay System, respectively.  (2318)

Neuroscience 102, 129-38. Nerve growth factor and glial cell line-derived neurotrophic factor restore the cholinergic neuronal phenotype in organotypic brain slices of the basal nucleus of Meynert. 2001

Weis, C., Marksteiner, J. and Humpel, C.

Notes: In Alzheimer's disease, cholinergic neurons are lost from the medial septum and nucleus basalis of Meynert. Nerve growth factor and glial cell line-derived neurotrophic factor were examined to determine if these growth factors can rescue the cholinergic neurons. GDNF and NGF levels in the sections of the basal nucleus of Meynert in rat was determined using Promega's GDNF Emax® ImmunoAssay System and NGF Emax® ImmunoAssay System, respectively. Glial cell line-derived neurotrophic factor was capable of partially restoring the number of cholinergic neurons.

J. Neurosci. 20, 9096-9103. Co-Induction of p75NTR and p75NTR-Associated Death Executor in Neurons After Zinc Exposure in Cortical Culture or Transient Ischemia in the Rat 2000

Park, J.A., Lee, J.Y., Sato, T.A., and Koh, J.Y.

Notes: Mixed mouse cortical cultures containing both neurons and astrocytes were treated with zinc to induce neuronal death. Nerve growth factor augmented this zinc-induced neuronal death. The p75NTR receptor and the p75NTR-associated death executor (NADE) also play roles in zinc-triggered neuronal death. NGF levels were determined using Promega's NGF Emax® ImmunoAssay System. (2333)
