Transcriptome analysis of mammary tissues reveals complex patterns of transporter gene expression during pregnancy and lactation
As a complex Ca2+-rich fluid mixture of water, casein, lactose and several ions, milk secretion requires a number of unknown transporters, which can be identified by a genome-wide microarray study in mammary tissues of lactating animals. Ca2+ was reported to be secreted across mammary epithelial cel...
