Identification of genes that define PEL. The 75 genes most associated with
PEL by using a Mann-Whitney U test (P values from 2.91
× 10-7 to 1.36 × 10-4). Each column
represents one sample, and each row represents one gene (identified by HUGO ID
and gene name). The majority of genes can be classified by their involvement
in either inflammation, adhesion, and invasion (blue) or ER, Golgi, and
vesicle trafficking (red).
