Deficiency of TTYH1 Expression Reduces the Migration and Invasion of U2OS Human Osteosarcoma Cells.

ABSTRACT: The Tweety homolog (TTYH) chloride channel family is involved in oncogenic processes including cell proliferation, invasion, and colonization of cancers. Among the TTYH family, TTYH1 is highly expressed in several cancer cells, such as glioma, breast, and gastric cancer cells. However, the role of TTYH1 in the progression of osteosarcoma remains unknown. Here, we report that deficient TTYH1 expression results in the inhibition of the migration and invasion of U2OS human osteosarcoma cells. We found that TTYH1 was endogenously expressed at both mRNA and protein levels in U2OS cells and that these channels were located at the plasma membrane of the cells. Moreover, we found that silencing of the TTYH1 with small interfering RNA (siRNA) resulted in a decrease in the migration and invasion of
