We found that the larval-specific genes such as AY762616 (UDP-glucose dehydrogenase) and BC042305 (solute carrier 22A6) may play a role in signal transduction and cell migration, while mucin, cytochrome P450, BC081224 (thioredoxin reductase), BC044116 (keratin 8) and BC056840 (lactotransferrin) are described as potential molecular markers for colon, breast and other cancers [24,25], suggesting that inappropriate expression of larval-specific genes in adult intestine may cause or be indicative of cancer formation. Here, UGDH is linked to cancer.
