assessment of mrna levels by hybridization to cloned cdnas , together with other measures of gene expression , established that the change in hepatocyte morphology was associated with strong activation of expression of genes normally activated later in development , including those coding for the liver enzymes tyrosine aminotransferase and phosphoenolcarboxykinase and a gene of unknown specificity that is regulated in liver much like the aminotransferase .
