查询词典 synthesize

Transcription factors can control the transcription of their target genes when they bind to the DNA-binding sites on their promotors. They can transfer the messages of growth factors and so on to those effective molecules. Core binding factor al is such a kind of transcription factor, which can control the differentiation of osteoblasts peculiarly. They can induce the pro-osteoblasts or non-osteoblasts to synthesize and secrete most mineralize related proteins such as ALP, OC, OPN, BSP and so on, in order to differentiate to osteoblasts finally.

转录因子是一类可以通过与下游靶DNA结合，从而调控下游基因转录的分子，它们接受来自生长因子等方面的信号，再将这些指令具体地传递给直接执行功能的蛋白分子。cbfal是一种成骨分化特异性转录因子，可以诱导成骨前体细胞合成和分泌ALP、OC、OPN、BSP等矿化相关蛋白，向成骨细胞分化。
