Besides, the expression of NASP did not significantly elevated or depleted in SKBR3 (represents Her2+ breast cancer cells) or MCF-7 (represents luminal breast cancer cells) cell lines (Figure S1), which was consistent with the result from GEPIA2 database showed in Figure 1A. Collectively, these results suggested that NASP was highly expressed in TNBC and related to poor prognosis. This evidence concerns the gene NASP and breast cancer.
