However, overexpression of full-length NDRG1 functions as a promoter of tumor growth and metastasis in ER-, aggressive breast cancers, which is consistent with the previous work demonstrating where silencing of NDRG1 prevented tumor formation in highly aggressive TNBC (Villodre et al., 2020; Villodre et al., 2022; Joshi et al., 2024). The gene discussed is NDRG1; the disease is neoplasm.
