Other genes related with metabolism like different metal transporters (copA, Cu + −exporting ATPase; cbiN, cobalt/nickel transport protein), enzymes involved in carbon metabolism (ACADS, butyryl‐CoA dehydrogenase; pycB, pyruvate carboxylase subunit B; gcvH, glycine cleavage system H protein), and a glutamate dehydrogenase (gudB), that allows the use of glutamate as a carbon source, were also more expressed in adenocarcinoma. This evidence concerns the gene COPA and adenocarcinoma.
