多胺是一类小分子脂肪族化合物 ,对维持细胞膜和线粒体的完整性、DNA和RNA结构的稳定性 ,以及在基因表达、信号转导、调节蛋白合成过程等方面都具有重要意义。在细胞凋亡过程中多胺浓度发生了变化 ;多胺的结构类似物和合成抑制剂的应用也对细胞凋亡产生了促进或阻碍作用。 Polyamines are a class of small aliphatic compounds that are important for maintaining the integrity of cell membranes and mitochondria, the stability of DNA and RNA structures, as well as in gene expression, signal transduction, and regulatory protein synthesis. Polyamines concentration changed during apoptosis; the use of structural analogues of polyamines and synthetic inhibitors also contributed to the inhibition or inhibition of apoptosis.
