The use of cDNA microarray to identify differentially expressed labor-associated genes within the human myometrium during labor

cDNA microarray was used to identify 56 differentially expressed genes in myometrium obtained from patients in spontaneous labor. The up-regulation of four genes was confirmed by multiple methods. Elucidation of the role(s) of the genes identified by microarray should improve our understanding of normal labor physiology and may ultimately lead to more effective treatments for abnormal labor.
