WebFigure 1: Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, as well as during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins. WebPart 3. Governing Gene Expression. Why it Is Important to Regulate Gene Expression Gene expression needs to be regulated in order to ensure that only the necessary genes are being expressed at the right time and in the proper amount. It permits cells to respond to environmental cues and also helps to maintain a balance between different cell types.

WebBacteria have specific regulatory molecules that control whether a particular gene will be transcribed into mRNA. Often, these molecules act by binding to DNA near the gene and … WebAll organisms and cells control or regulate the transcription and translation of their DNA into protein.

WebThus, our data suggest that gemcitabine resistance in breast cancer cells is mainly mediated by activation of the PI3K/AKT signaling pathway. This occurs through elevated expression of p-AKT protein to promote cell proliferation and is negatively regulated by the MEK/MAPK and mTOR pathways.
