We have compared the transcriptome in blood leukocytes, liver, and brain of humans, chimpanzees, orangutans, and macaques using microarrays, as well as protein expression patterns of humans and chimpanzees using two - dimensional gel electrophoresis. (science.sciencemag.org)
A reliability score is set manually for all genes and indicates the level of reliability of the analyzed protein expression pattern based on available protein / RNA / gene characterization data from both HPA and the UniProtKB / Swiss - Prot database. (proteinatlas.org)
The idea is that blood vessels in, say, the prostate have protein expression patterns different from those in vessels in the lung and that blood vessels in cancer tissue have expression patterns different from those in healthy tissue. (sciencemag.org)
