We pretreated the BEAS‐2B and breast cancer (MDA‐MB‐231) cells with TDZ and deliberated alteration in a cell viability, mammosphere, migration, NF‐кB signalling, PI3K/AKT signalling and matrix metalloproteinase (MMP) expression and analysed the EMT induction by TGF‐β/TNF‐α‐stimulated BEAS‐2B cells. The gene discussed is AKT1; the disease is breast carcinoma.
