Therefore, in this work, we quantified the effect of MβCD on the sensitivity of cervical carcinoma M-HeLa cells, which normally do not synthesize E-cadherin [26], colorectal adenocarcinoma epithelial Caco-2 cells, and breast cancer MCF-7 cells, which should synthesize E-cadherin characteristic of epithelial cells [27], to opportunistic bacteria S.grimesii and S.proteamaculans. The gene discussed is CDH1; the disease is cervical carcinoma.
