Definition of Gene-expression profiling
Gene-expression profiling: A genomic technique that based on the fact that only a fraction of the genes encoded in the genome of a cell are expressed by being transcribed into messenger RNA (mRNA). The complement of mRNAs in a cell largely dictates its complement of proteins. Consequently, gene expression is a major determinant of the biology of both normal and malignant cells.Source: MedTerms™ Medical Dictionary
