The Changes of c-Fos Expression by Motor Cortex Stimulation in the Deafferentation Pain Model
The effect of motor cortex stimulation (MCS) therapy for deafferentation pain was evaluated based on c-Fos, a known pain marker. Nineteen mature cats weighing 1.5-3.5 kg were used. Cats were divided into three groups: a deafferentation pain group in which the left trigeminal ganglion was destroyed, an MCS group in which MCS was used following destruction of the trigeminal ganglion, and a contro...
متن کاملTactile experience induces c-fos expression in rat barrel cortex.
Understanding gene expression that is responsive to sensory stimulation is central to elucidate molecular mechanisms underlying neuronal plasticity. In this study we demonstrate two new methods of stimulating whiskers that provide major sensory input to rat neocortex. In the first paradigm, animals were placed on the top of a cylinder and their vibrissae were brushed by hand. In the second para...
متن کاملc-Fos induces apoptosis in germinal center B cells.
We examined the role of c-Fos in the differentiation of mature B cells into IgG-producing cells using transgenic mice carrying the c-fos gene under the control of the IFN-alpha/beta-inducible Mx promoter (Mx-c-fos) or the constitutive H-2Kb promoter (H2-c-fos). Splenic B cells from Mx-c-fos mice were cultured with LPS and rIL-4, and IgG1+ B cells were developed in the culture after day 3. When ...
متن کاملInsulin stimulates phosphorylation of c-Jun, c-Fos, and Fos-related proteins in cultured adipocytes.
In differentiated 3T3-F442A adipocytes, insulin stimulated rapid and transient phosphorylation of c-Jun. Insulin also stimulated phosphorylation of c-Fos and several Fos-related proteins (pp72, pp45, and pp39) as indicated by precipitation with anti-c-Fos antibody following exposure to denaturating conditions. Phosphorylation of c-Fos was stimulated by 7-fold by 60 min, while phosphorylation of...
متن کاملMicroinjection of transforming ras protein induces c-fos expression.
Microinjection of p21ras induced c-fos protein accumulation in three types of 3T3 cells. The induction was rapid and efficient and persisted for many hours. In addition, anti-ras antibody dramatically reduced c-fos accumulation after serum stimulation of injected cells. However, cells which expressed p21ras continuously did not maintain a high level of c-fos expression.
