GADD45A and hepatocellular carcinoma: The results showed that the mRNA level of GADD45B, instead of GADD45A and GADD45G, strongly correlated with KDM1A in HCC cells (Figure S9A), which is consistent with data from the TCGA (Figure S9B), International Cancer Genome Consortium (Figure S9C), and Gene Expression Omnibus (GEO; Figure S9D) databases.
