| In cellular biology, the most basic functions that explain how genetic information is managed into protein and other required molecules are gene expression and regulation. Gene expression is defined as the process of using the information found in a gene to synthesize a gene product that is functional, commonly a protein. It usually involves two major processes: transcription, whereby DNA gets converted into messenger RNA (mRNA), and translation, whereby mRNA gets used to construct proteins. Gene regulation is central to functional and plastic cellular properties. It should permit appropriate gene expression at the appropriate times and in appropriate amounts so that the cell can appropriately respond to environmental and developmental cues. Important mechanisms of gene regulation include transcriptional control, primarily through regulatory protein and enhancer action on initiation of transcription, and post-transcriptional control, involving mRNA splicing, stability, and degradation. All of these involve epigenetic modifications, DNA methylation, and modification of the histone associated with the chromatin that change the chromatin structure and access to regulate gene expression without any change in the DNA sequence but with long-term changes in gene expression. Gene expression and regulation are the most important aspects in the development of medical research, especially in the light of targeted therapies, like anticancer therapy and disorders with genetic association. With the manipulation of gene expressions, scientists can reveal the new treatments and much more about intricate biological processes. |
