Very interestingly, and in line with our results showing the regulation of meprin α expression by Reptin, we found that meprin α expression was significantly and positively correlated with that of Reptin in HCC (Spearman r = 0.23, p = 0.0003), whereas no correlation was found for meprin β (Spearman r = 0.083, p = 0.20). The gene discussed is MEP1B; the disease is hepatocellular carcinoma.
