provide and explanation how gene expression can influence

Solution

gene expression analysis can provide a very homogeneous picture of organs and allow clear distinction between subtoxic and toxic doses of even novel drugs in human body.it is a sensitive indicator of biological activity, processes and change. Almost any biological activity is reflected in a changing gene expression pattern that can be measured with microarrays. Most major institutions conducting biological research have established gene expression core facilities and many are now in the process of upgrading to high-throughput systems to apply these technologies to clinical trials, basic research and biomarker discovery programmes. Clearly, gene expression study is now integrated into life science research and drug development in a variety of productive ways.

The main disadvantage is its too complicated procedure.It is not effective in pathogens which pathophysiology of disease is unknown.
