    ..Furthermore, knockdown of GNB4 decreased growth of both antiestrogen resistant and sensitive breast cancer cells. GNB4 is important for growth of breast cancer cells and a potential target for treatment. ..
  4. Wang B, Li D, Filkowski J, Rodriguez Juarez R, Storozynsky Q, Malach M, et al. A dual role of miR-22 modulated by RelA/p65 in resensitizing fulvestrant-resistant breast cancer cells to fulvestrant by targeting FOXP1 and HDAC4 and constitutive acetylation of p53 at Lys382. Oncogenesis. 2018;7:54 pubmed publisher
    ..HER2/NF-?B (p65)/miR-22/HDAC4/p21 and HER2/NF-?B (p65)/miR-22/Ac-p53/p21 signaling circuits may therefore confer this dual role on miR-22 through constitutive transactivation of p21. ..
