Oncofetal SNRPE promotes HCC tumorigenesis by regulating the FGFR4 expression through alternative splicing.

Background: Due to insufficient knowledge about key molecular events, Hepatocellular carcinoma (HCC) lacks effective treatment targets. Spliceosome-related genes were significantly altered in HCC. Oncofetal proteins are ideal tumor therapeutic targets.

5-Azacytidine promotes HCC cell metastasis by up-regulating RDH16 expression.

The level of DNA methylation could affect the expression of tumor promoting and tumor suppressor genes. DNA methyltransferase inhibitors could reduce high methylation levels in cancer and inhibit the progression of a variety of cancers, including HCC. However, the pro-metastatic effect of DNA methyltransferase inhibitors in some cancers suggest the potential risk of their use.

Osteopontin promotes hepatocellular carcinoma progression through inducing JAK2/STAT3/NOX1-mediated ROS production.

Osteopontin (OPN) is a multifunctional cytokine that can impact cancer progression. Therefore, it is crucial to determine the key factors involved in the biological role of OPN for the development of treatment. Here, we investigated that OPN promoted hepatocellular carcinoma (HCC) cell proliferation and migration by increasing Reactive oxygen species (ROS) production and disclosed the underlying mechanism.
