15301711-1	2004	BACKGROUND & OBJECTIVE: Accumulating evidences showed that the overexpression of multidrug resistance-associated protein 2 (MRP2) was the main cause of multidrug resistance in hepatocellular carcinoma (HCC); and the methylated cytosine at cytosine-guanine (CpG) dinucleotides might silence the gene expression.	cytidylyl-3'-5'-guanosine	261-279	ATP binding cassette subfamily C member 2	Homo sapiens	85-126
