Abstract

The gene solute carrier family 34 (sodium phosphate), member 2 (SLC34A2), is a member of the SLC34 family. Increasing evidence suggests that SLC34A2 is involved in the development of many human carcinomas. However, its role in hepatocellular carcinoma (HCC) is still unclear. Therefore, in this study we investigated the role of SLC34A2 in HCC and explored the underlying mechanism. We found that the expression of SLC34A2 is upregulated in HCC cell lines. Knockdown of SLC34A2 obviously inhibited HCC cell proliferation, migration/invasion, and the epithelial–mesenchymal transition (EMT) phenotype. Furthermore, knockdown of SLC34A2 significantly inhibited the expression of phosphorylated PI3K and AKT in HCC cells. Taken together, these results suggest that knockdown of SLC34A2 inhibits proliferation and migration by suppressing activation of the PI3K/AKT signaling pathway in HCC cells, and SLC34A2 may be a potential therapeutic target for the treatment of HCC.
