Performed DNA microarray analysis to determine which genes were differentially regulated in mice housed in the enriched environment compared to standard cages.The methods predicated on plant biotechnology are an alternative to chemical synthesis. By controlling the cell fat burning capacity of a ‘green factory’, i.e. A living plant cell, it is possible to affect the production of desired high-value compounds. This type of metabolic engineering stimulates the cells towards producing new compounds also. Plants generate important secondary metabolic substances, which can be used as pharmaceuticals. Most of these compounds are so complicated that their chemical synthesis is not economically feasible.
