High correlations in gene expression between paired umbilical cord blood and neonatal blood of healthy newborns on Guthrie cards.


ABSTRACT: To examine the correlation in genes expressed in paired umbilical cord blood (UCB) and newborn blood (NB).Total mRNA and mRNA of three gene sets (inflammatory, hypoxia, and thyroidal response) was assessed using microarray in UCB and NB spotted on Guthrie cards from 7 mother/infant pairs.The average gene expression correlation between paired UCB and NB samples was 0.941 when all expressed genes were considered, and 0.949 for three selected gene sets.The high correlation of UCB and NB gene expression suggest that either source may be useful for examining gene expression in the perinatal period.
