Expression of STAR1 was upregulated in breast cancer cell lines (Supplementary Fig. S2B) and also in breast cancer tissue compared to its nearby normal tissue (N = 30, P-value < 0.05), similar to KLHDC7B (N = 28, P-value < 0.05) (Fig. 2A,B). The gene discussed is KLHDC7B; the disease is breast cancer.
