查询词典 active nucleus

It has a nucleus, dense cytoplasm, and many mitochondria, and is thought to provide, Via PLASMODESMATA, the needs of the less metabolically active, enucleated sieve element and perhaps plays a role in regulating the flow of metabolites through the sieve tube.

伴胞具有细胞核和浓厚的细胞质，还有大量的线粒体提供能量。筛管分子去除细胞核，仍能生活，可能与伴胞的存在有关。

TGF-βbinds to a heteromeric complex of type I and type II receptors. The constitutively active type II receptor phosphorylates and activates the type I receptor which phosphorylates Smad2 and Smad3 (receptor-associated Smads). Receptor-associated Smads bind the common mediator Smad4 and are translocated to the nucleus, where they associate with DNA-binding cofactors to modulategene transcription.

TGF-β与其效应细胞表面的Ⅱ型受体TβRⅡ和Ⅰ型受体TβRⅠ形成的异源二聚体结合，相继激活TβRⅡ和TβRⅠ，活化的TβRⅠ再进一步活化Smad2和Smad3，磷酸化的Smad2/3必须与Smad4结合形成复合物，才能进入细胞核，调节靶基因的转录[6]。

Active brain regions of awake word＞anesthesia word in group D were observed in left thalamus,precentral gyrus,anterior cingulate and right basal nucleus.

But the big finding is that the cell nucleus has two compartments—and genes are only active in one.

但是，最大的发现是细胞核有两个分隔，基因只在其中一个中活动。

It was suggested that one of the radical reasons resulting in microspore abortion of alloplasms was the disorder between nucleus and cytoplasm, which caused unbalance of enzymatic metabolism, decrease of activities of SOD and CAT, and damage of membrane systems led by accumulated active oxygen.

异质系核质关系不协调，酶代谢失调，SOD、CAT活性下降，活性氧积累导致膜系统损伤，可能是异质系花粉败育的根本原因之一。

LKB1, the main upstream AMPK kinase in peripheral tissues, was redistributed from the nucleus into the cytoplasm of cells treated with SU6656 and in cells expressing a kinase-deficient, but not a constitutively kinase-active, Fyn mutant.
