To determine the effect of TCAF2+ TPCs on tumor metastasis, TPCNM with an intrinsically low level of TCAF2 were transfected with a TCAF2 overexpressing plasmid (TPCNMTCAF2) (Figure S11A,B, Supporting Information), and TPCLM with naturally higher TCAF2 expression were transfected with short hairpin RNA (shRNA) to construct TCAF2‐knockdown TPCs (TPCLMshTCAF2) (Figure S11C,D, Supporting Information). This evidence concerns the gene TCAF2 and neoplasm.
