In another statistical analysis study based on the human triple-negative breast cancer (TNBC) cell line HS578T, the expression level of DDIT4 was negatively correlated with the levels of tumor-infiltrating immune cells and immunobiological markers, while positively correlated with the expression levels of various immune checkpoint molecules, including PD-L1 and CTLA4 (38). This evidence concerns the gene DDIT4 and neoplasm.
