Functional analysis of early and late sets. (A) Comparison of pathway analysis between early and late sets. A probability value of 0.05 was applied for the analysis. (B) Top network Cellular Development, Hematological System Development and Function, Hematopoiesis associated with the early sample set (C) Top network Organismal Injury and Abnormalities, Respiratory Disease, Cell-To-Cell signaling and Interaction associated with the late sample set. Red color indicates higher level of expression in disease and green color indicates lower level of expression in disease. The names of the genes are in nodes. The shape of the nodes is related to gene function/family membership. The lines between the nodes represent the connectivity between genes. Solid lines indicate direct protein-protein interactions. Dotted lines represent indirect interactions.
