ALB and hepatocellular carcinoma: Then, we explored an external microarray-based mRNA expression dataset from 247 HCC patients [28] (GSE14520), which confirmed positive correlations of GSTA1 with albumin and procollagen type XVIII (not shown) and showed additional positive correlations with the liver-enriched transcription factor HNF4A [29] and the liver-specific methionine adenosyltransferase MAT1A [30] (S1 Table).
