COL5A2 and acute lymphoblastic leukemia: Although some pathways are present in more than one comparison, such as "extracellular matrix organisation" and "extracellular structure organisation" in both SUP with ALL and INF with ALL comparisons, they are represented by different genes, such as SFRP2 (in SUP with ALL) and MYH11, COL5A2, and COL8A1 (in INF with ALL), all up regulated in the ALL samples when compared to the others.
