Nicotine-stimulated proteins in mouse cells are distinct from heat-shock proteins. 1984

L A Hunt, and K S Kelley

Treatment of mouse tissue-culture cells with nicotine concentrations of 1 mM or less had no significant effects on cell viability, morphology or protein synthesis, but higher concentrations resulted in both altered cell morphology (rounding and vacuolization) and alterations in [3H]leucine-labelled protein profiles on sodium dodecyl sulphate/polyacrylamide gels. The synthesis of a Mr-70 000 protein was increased more than 2-fold relative to that of other major cellular proteins in 3T3 and L929 cells treated with 5 mM-nicotine and in B16 cells treated with 10 mM-nicotine, and this protein appeared to be a soluble cytoplasmic polypeptide. The radiolabelling of several additional polypeptides (Mr 62 000 in 3T3 cells, and Mr 45 000 and 38 000 in B16 cells) was also stimulated by nicotine. The nicotine-enhanced Mr-70 000 protein was distinct, however, from a major cell stress/heat-shock protein whose synthesis was stimulated after incubation of cells at 43.5 degrees C for 20 min.

D008807 Mice, Inbred BALB C An inbred strain of mouse that is widely used in IMMUNOLOGY studies and cancer research. BALB C Mice, Inbred,BALB C Mouse, Inbred,Inbred BALB C Mice,Inbred BALB C Mouse,Mice, BALB C,Mouse, BALB C,Mouse, Inbred BALB C,BALB C Mice,BALB C Mouse
D009538 Nicotine Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke. Nicotine Bitartrate,Nicotine Tartrate
D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D002470 Cell Survival The span of viability of a cell characterized by the capacity to perform certain functions such as metabolism, growth, reproduction, some form of responsiveness, and adaptability. Cell Viability,Cell Viabilities,Survival, Cell,Viabilities, Cell,Viability, Cell

D006360 Heat-Shock Proteins Proteins which are synthesized in eukaryotic organisms and bacteria in response to hyperthermia and other environmental stresses. They increase thermal tolerance and perform functions essential to cell survival under these conditions. Stress Protein,Stress Proteins,Heat-Shock Protein,Heat Shock Protein,Heat Shock Proteins,Protein, Stress
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
