Moreover, SATB1 expression and anoikis resistance were mainly regulated by HBV-encoded viral protein HBx through the activation of ERK and p38 MAPK signaling pathways to promote metastasis of liver cancer.
These results show that in addition to changes in the signaling pathways, such as the Ras-Raf-MEK-ERK pathway, altered mitochondrial DNA replication and protein folding in liver cancer are also worth studying further.
The protein levels of p-ERK, p-JNK and p-p38 and the protein levels of MMP-2 and MMP-9 were evaluated with western blot 48 h after siRNA-B-targeting BMP-2 was transfected into liver cancer SMMC7721 cells.
Taken together, our results emphasize the importance of the MEK/ERK pathway in liver cancer cell growth in vitro and in vivo and argue for a crucial role of ERK2 in this regulation.
