In the article titled “Role of Interleukin-18 in Modulation of Oral Carcinoma Cell Proliferation” [1], KB cells have been found to be cross-contaminated by HeLa cells [2], which means that KB is really a cervical cancer line and not an oral cancer line. Accordingly, no conclusions can be drawn relating specifically to oral cancer.
