Gene expression can be regulated at several levels in a cell. Differential gene transcription regulates which genes are allowed to be transcribed into RNA while selective nuclear RNA processing regulates which transcribed RNA can enter the cytoplasm and become messenger RNA. Genes can be regulated any...

What Is Gene Expression: The central dogma describes the flow of information from DNA (gene) to protein. Gene expression is the process of converting the genetic code to functional proteins for the cell to use. Gene expression is highly regulated and requires 3 different types of RNA: messenger...
While biosynthesis, intracellular transportation and secretion of circulating hormones and cytokines are regulated in response to the physiological demands of whole body, with or without changes in the adipocyte mass. Expression of adiponectin gene was found unchanged per cell (-1.1%, p=0.27), ...
Matrix metalloproteinase (MMP) gene expression occurs under tightly regulated mechanisms that lead to cell and tissue-specific expression of the individual genes. Despite this differential expression,there exists a high degree of similarity among the cis-acting elements in the MMP promoters.The Activator...
The transformation process is also characterized by changes in the pattern of gene expression. Whereas some of the genes are up-regulated (e.g. SAGs), others are down-regulated (e.g. photosynthetic genes). Generally, most of the up-regulated genes have been shown to play a role in the ...
38K This lesson will discuss the concept of gene regulation, how genes are regulated, as well as some mechanisms that enable it. It will also cover the reasons that make gene regulation important. Related to this QuestionWhat is a DNA-binding protein motif? What is a DNA binding vesicant?
The expression pattern of VEGF isoforms, which is strictly regulated in normal conditions, is disrupted in diseases; for example, in vivo it has been shown that in pathological retinal neovascularization of rodents, the VEGF164/VEGF120 ratio undergoes a ten-fold increase (∼25.5 versus ∼2.2 ...
