c fos基因是一种原癌基因 ,属于即刻早期基因类 (IEG)。在口内或胃内给予各种化学刺激活 ,可以激活脑内相应的味觉和内脏神经元 ,从而引起正常大鼠及不同模型大鼠脑内相关核团中c fos蛋白的表达。通过味觉刺激及内脏刺激与脑内核团c fos原癌基因表达的比较研究 ,可为味觉信息与内脏信息在大脑中的相互作用机制提供有力的证据。
The c fos gene is a protooncogene belonging to the immediate early gene class (IEG). In the mouth or stomach to give a variety of chemical stimuli can activate the brain corresponding taste and visceral neurons, causing normal rats and different rat brain c fos protein expression. Through the comparison of taste stimulus and visceral stimulation with c fos proto-oncogene expression in brain nucleus, it can provide strong evidence for the interaction mechanism of taste information and visceral information in the brain.
