Up-regulation is a process that occurs within a cell triggered by a signal (originating internal or external to the cell), which results in increased expression of one or more genes and as a result the protein(s) encoded by those genes.
Genetic control of the cell is carried out by the production of RNA in the nucleus (the process of transcription) and the subsequent transfer of this RNA to a ribosome in the cytoplasm, where protein synthesis (the process of translation) is directed.
