TCP1 and lymphoma: In order to know if TCP-1 mediates the function that P2X7R inhibits the metastasis of murine lymphoid neoplasm cells to lymph nodes, we reduced the expression of TCP-1 in the P388D1, L5178Y and L1210 cell lines by TCP-1 shRNA and finally found that down-regulating TCP-1 could inhibit lymphoma cells metastasis in vivo.
