Protein expression levels of DDX3 analyzed by immunohistochemical staining are also subjected to similar classification (see Materials and Methods). (cancerres.aacrjournals.org)
Association of a protein biomarker with any given disease process, for example, needs to be assessed in terms of disease - independent, confounding factors that may modulate protein expression levels among different individuals. (sciencemag.org)
This new study suggests that the major reason why protein and mRNA abundance measurements are poorly correlated is because of various types of measurement error in the protein and mRNA abundance, rather than transcription having minimal impact on protein expression levels. (sciencedaily.com)
