Methods: A total of 35 patients were collected between January 2016 and December 2018. The copy number and expression level of MMP-9 were measured in 35 HCC tumor tissues and 35 paired adjacent non-tumor tissues using digital polymerase chain reaction (dPCR) and quantitative reverse transcription polymerase chain reaction (RT-qPCR), respectively.
Results: Our results showed that MMP-9 expression was significantly upregulated in HCC tumor tissues compared to adjacent non-tumor tissues (5.521±9.545 versus 1.000±0.000, P=0.0047). Interestingly, MMP-9 CNVs only existed in tumor tissues (15/35 versus 0/35, P=0.002). A breakdown analysis by the occurrence of CNVs in tumor tissues had shown that there were significant differences between CNVs group and non-CNVs group in the expression levels of tissue alpha-fetoprotein (AFP) (P=0.015), tumor size (P},
