Abstract

Liver cancer is the fifth leading cause of mortality attributed to cancer. Among various histological types, hepatocellular carcinoma (HCC) is the most prevalent form of liver cancer. There is a need to identify new biomarkers to help the physician, and allow them to decide what may be the most effective treatment for the patient. POTE-2 is one of the 14 paralogs apart of the ancestral POTE gene family. POTE-2 has been shown to be upregulated in non-small cell lung cancer and colorectal cancer, and is associated with increased migration, invasion, tumor size and poor survival. Evaluation of the Cancer Genome Atlas for POTE-2 in liver cancer showed increased expression in malignant vs tumor and expression correlated with increased stage and grade. This was further validated through a liver cDNA and tissue microarray. Gain of function studies showed increased phosphorylation of major kinases and increased cellular invasion. The findings indicate that POTE-2 expression is increased in cancer, is associated with advanced cancer, and could play a significant role in cancer progression.
