Influencing Factors Regulating the Expression of the Macrophage Migration Inhibitor Factor (MIF) Gene / 中国生物化学与分子生物学报

ABSTRACT

Macrophage migration inhibitory factor (MIF) is a widely expressed multipotent cytokine that participates and plays an important role in various inflammatory and immune diseases‚ and is a biomarker or therapeutic target of many diseases. MIF is highly conserved in phylogeny and there are specific binding sites of various transcription factors in its promoter region‚ which can regulate the expression of MIF. MIF functions both inside and outside cells‚ and MIF is constitutively expressed. Therefore‚ it is of great significance to study the related factors that regulate MIF gene expression and stimulate MIF secretion. This article summarizes and classifies the related factors affecting MIF gene expression by briefly describing the binding sites on the MIF gene and MIF promoter. According to the way of binding with the MIF gene‚ it can be divided into:(1) binding to specific sites of MIF gene promoters to change transcription activity; (2) binding to MIF CATT5-8 microsatellite repeats to change highly expressed MIF alleles (3) non-coding RNAs regulating MIF expression; (4) related factors affecting MIF secretion. By reviewing the four types of related factors that regulate MIF gene expression‚ we will understand the regulatory mechanism and influencing factors of MIF gene expression‚ in order to provide a theoretical basis for its treatment of related diseases.
