MTA1 modulated by miR-30e contributes to epithelial-to-mesenchymal transition in hepatocellular carcinoma through an ErbB2-dependent pathway
MTA1 is a metastasis-associated protein, which is essential to epithelial-to-mesenchymal transition (EMT). However, information concerning its up- and downstream regulation is rare. We investigated its upstrea...

HBx-mediated miR-21 upregulation represses tumor-suppressor function of PDCD4 in hepatocellular carcinoma
The hepatitis B virus (HBV) X protein (HBx) has a key role in the molecular pathogenesis of HBV-related hepatocellular carcinoma (HCC). However, the mechanism of HBx-mediated hepatocarcinogenesis remains to be...

Human mesenchymal stem cells overexpressing pigment epithelium-derived factor inhibit hepatocellular carcinoma in nude mice
The poor outcome of cancer gene therapy in clinical trials relates in part to insufficient gene delivery to tumor sites. Mesenchymal stem cells (MSCs) represent a new tool for the delivery of therapeutic agent...
