Neurotrophins (NGF, BDNF, NT-3, and NT-4) and their transmembrane receptors (TrkA, TrkB, TrkC, and P75NTR) play important roles in the regulation of neuronal and non-neuronal cell proliferation, differentiation, survival, and death. Neurotrophin signaling also mediates higher-order neuronal activities, such as learning, memory, and behavior. Alterations in neurotrophin levels and their receptors have been implicated in neurodegenerative disorders, such as Alzheimer's disease and Huntington's disease, as well as psychiatric disorders. Neurotrophins propagate their signal through activating mult...

Jak/Stat signaling pathways play essential roles in the cellular responses to distinct cytokines. One of the Jak/Stat pathways, Jak2/Stat5, mediates cell proliferation in response to Interleukin - 3 (IL - 3), prolactin, erythropoietin (Epo), and granulocyte - macrophage colony stimulating factor (GM - CSF). JAK2 gene knockout causes embryonic lethality due to defective erythropoiesis, suggesting that the Jak2/Stat5 pathway plays an important role in red blood cell formation. The recent discovery of an activating mutation in JAK2 (V617F) present in a high percentage of myeloproliferative diseas...

LanthaScreen™ GFP Cellular Assays allow for the analysis of post-translational modifications for a number of target proteins in an live-cell context. The JAK2⁄STAT5 signaling pathway plays an essential role in blood cell formation in response to cytokines such as GM-CSF, IL-3, and EPO. The recent discovery of an activating mutation in JAK2 (V617F) present in high percentage of myeloproliferative disease (MPD) patients suggests that this mutant JAK2 activity is a potential therapeutic target for certain forms of MPD. The assay described in this summary makes use of a cell line engineered for ex...

Activation of the heat shock response⁄unfolded protein response (HSR⁄UPR) occurs in response to a diversity of chemical, environmental, and physiological stress conditions. Transcriptional regulation of the human HSR is mediated by a family of three heat shock transcription factors (HSFs), HSF-1, -2, and -4. Stress-induced activation of quiescent HSF monomers results in their trimerization and accumulation in the nucleus, wherein they bind to and upregulate transcription of target genes (e.g. molecular chaperones, certain proteases, and other stress response genes) harboring a heat shock eleme...

The Calcium Phosphate Transfection Kit provides high-quality reagents to enable the introduction of DNA into eukaryotic cells via calcium phosphate co-precipitation. How it works The calcium phosphate transfection method for introducing DNA into mammalian cells is based on forming a calcium phosphate-DNA precipitate. Calcium phosphate facilitates the binding of the DNA to the cell surface. DNA then enters the cell by endocytosis. The method was first developed by Graham and van der Ebb and was later modified by Wigler. The procedure is routinely used to transfect a wide variety of cell types f...
