摘要
G蛋白是一个调节GTP水解酶的超家族,在细胞增殖和分化信号转导过程中发挥关键性作用。半个世纪前人们已发现氟化物可以抑制各种酶,氟化物是公认的G蛋白激活剂。尽管目前对于氟化物作用于G蛋白的机制还不完全清楚,但国内外研究均显示氟中毒与G蛋白有关。通过本文可以了解到氟化物作为一个骨形成因子是如何作用于G蛋白而影响成骨细胞增殖,对进一步研究氟中毒致病机理具有一定的参考价值。
G protein is a superfamily of regulatory GTP hydrolases. They play pivotal roles in the signal transduction of cell growth and differentiation. Fluoride had been found to inhibit a variety of enzymes for more than half a century. Fluoride is a well-known G protein activator. The actual mechanism of fluoride action on guanine nucleotide-binding component of AC remained elusive. Many studies seem to suggest a correlation between fluorosis and G protein. The aim of this review is to discuss the basic chemical, biochemical, and toxicological properties of metallic fluoride, to understand the role of Al-F and Be-F complexes in human physiology and its potential effects on our health.
