Consistently with these data, GSTA1 mRNA levels were negatively correlated with tumor size (P = 0.007, Fig 4B), and positively correlated with the mRNA expression of the liver-enriched genes albumin (P = 0.001, Fig 5A) and procollagen type XVIII (P = 0.03, Fig 5B). This evidence concerns the gene GSTA1 and neoplasm.
