RETRACTED

BioMed Research International has retracted this article. As noted by Amanda Capes-Davis on PubMed Commons, KB cells are cross-contaminated by HeLa and are not oral cancer cells [2]. Therefore, the conclusions cannot be supported. Tan IIA was already known to induce apoptosis in HeLa cells through a mitochondria-dependent pathway [3].
