“…The proteins of blood were all first expressed as mRNAs from genes within tissues and cells. The nucleotides of the parent genome, or mRNA transcripts converted to cDNAs, may be sequenced and the proteins inferred (Soll et al, 1965;Brutlag et al, 1969;Cohen & Chang, 1974;Sanger, Nicklen, & Coulson, 1977;Smith et al, 1986;Mullis, 1990;Hutchinson & Hayden, 1992;McCombie et al, 1992;Adams et al, 1993;Zhang, 1997;Brenner et al, 2000;Venter et al, 2001;SanchezCarbayo et al, 2002;Knapp & Chen, 2007). Each gene, its mRNA, and protein are uniquely regulated at multiple levels including transcriptional, post-transcriptional, translational, post-translational, processing and turnover in response to developmental, physiological or environmental conditions (Gygi et al, 1999b).…”
