Conversely, Acinetobacter baumannii has been linked to the inhibition of breast tumor invasion, potentially via its glutaminase activity, which influences cancer cell metabolism [85] or by the production of natural anticancer compounds, including Cinerubin B and Actinomycin V, demonstrated antiproliferative effects, inhibition of epithelial–mesenchymal transition (EMT), and suppression of tumor cell migration and invasion [84]. The gene discussed is GLS; the disease is cancer.
