Summary and prospect of medicinal plant active substances in regulation of p65 nuclear translocation / 中国中药杂志

ABSTRACT

As the most important nuclear transcription factors in the cells, NF-κB is involved in many intracellular signaling pathways and transcription and regulation of genetic information. The signal transduction pathways mainly include the activation of IκB kinase, degradation of IκB protein and the nuclear translocation of p65. p65 trans-nuclear binding with DNA is the key for NF-κB to play a role. Abnormal activation of NF-κB is a major factor in the induction of oxidative stress, inflammation, cancer and so on. Therefore, maintaining the balance of NF-κB activity and regulating the nuclear translocation of p65 have great significance for further research on related subjects. In this paper, the regulation effects of the main active substances of medicinal plants (such as polyphenols, saponins, and alkaloids) on p65 nuclear translocation and the upstream pathway of NF-κB were discussed, expecting to provide reference for the development of natural active substances for functional food.
