Microarray and quantitative reverse transcription-polymerase chain reaction (qPCR) analyses of hepatocellular carcinoma (HCC) HEP3B cells revealed that EGCG upregulated MMP1, MMP9, and long non-coding RNA ADAMTS9 and downregulated the expression of MMP11, MMP24 and a disintegrin and metalloprotease (ADAM) family protein ADAMTSL4 [40]. This evidence concerns the gene ADAMTS9 and hepatocellular carcinoma.
