Given the important role of TGF‐β1 in EMT progression,[32] we detected the mRNA expression of EMT‐related genes (E‐cadherin, N‐cadherin, and Vimentin) in radiated versus non‐radiated tumor cells by qRT‐PCR and found that RT upregulated N‐cadherin and Vimentin mRNA of 4T1, CT26, H22, and GL261 tumor cells (Figure S2a, Supporting Information). Here, VIM is linked to neoplasm.
