﹡基因表达调控(gene expression regulation and control)指通过生物体内的调控系统来调节和控制体内蛋白质的含量与活性,使之在特定的时间、特定的空间、并以一定的强度出现,以适应机体生长、发育和繁殖的需要。光修复酶基因光修复酶DNA损伤紫外光照射AB二、基因表达的特异性(一)时间特异性在生物体不同的功能阶段,按...
Long non-coding RNAs (lncRNAs) are diverse transcription products emanating from thousands of loci in mammalian genomes. Cis-acting lncRNAs, which constitute a substantial fraction of lncRNAs with an attributed function, regulate gene expression in a manner dependent on the location of their own sites...

APP intracellular c-terminal domain (AICD), produced by sequential α- or β- and γ-secretase cleavages, is thought to control gene expression, similarly as the ICD of Notch. To investigate the role of APP family in transcriptional regulation, we examined gene expression changes in the ...
We now know that genes encode proteins and control the functions of a cell. Are all the genes in a cell expressed at the same time? Are all genes expressed all the time? No! This will lead to wastage of cellular energy. So gene expression is regulated. H
