Consistently, immunohistochemistry (IHC) analysis using tissue microarray that included n = 92 TNBC primary cancer specimens confirmed this result, showing that the expression of PISD was decreased, whereas the expressions of SLC1A5, TYMP, and PDZD11 were significantly increased in TNBC tissues compared with PNTs (Figure 4E). Here, SLC1A5 is linked to cancer.
