Transcriptional profiling of the cardiac left ventricle during pregnancy and the early post-partum period

Comparative analysis was done to identify genes and pathways affected in the heart left ventricle during different stages of pregnancy. Microarray profiling was done on nonpregnant, pregnant, and early post-partum mice, with diestrus females serving as reference. Two replicates of each type of sample were analyzed (n=2). The diestrus sample serves as reference for three pregnancy-related states (pregnant day 12, pregnant day 19, and post-partum day 1.5).
