  1. Functional annotations that are enriched among transcripts downregulated in myosin heavy chain (MHC) positive cells (intersection of down-regulation in the 15-day-old α-MHC+ cardiomyocytes [twofold, Student's t-test P value < 0.01] compared with the control cells in the 15-day-old embryoid bodies and compared with the undifferentiated α-MHC embryonic stem cells). 'Count' refers to the number of transcripts in the respective category; the 'P value' column shows the value of Fisher's exact t-test, as used by DAVID to measure the enrichment in annotation terms.
