RPS14 and breast cancer: Additionally, the RNA expression levels of SLC19A1 and RPS14 were validated in human breast cancer cell lines (Supplementary Figure S2), the result of which demonstrated that SLC19A1 was significantly promoted in breast cancer cell lines including MDA-MB-231, T47D, and SK-BR-3 while RPS14 declined significantly in BC cell lines comparing with breast epithelial cell line MCF10A.
