MAPT and malignant colon neoplasm: To determine the cell cytotoxicity elicited by either (0.5–10 mM) BAT or (5–200 mM) Tau, human colon cancer cells (RKO, Caco2, HT-29), human breast cancer cells (MDA-MB-231, MDA-MB-468), human skin cancer cells (WM-164), and human cervical cancer cells (HeLa) were incubated with serial dilutions of BAT (Figure 1) or Tau (Figure 2) for 24–72 h and then, the Crystal Violet assay was performed.
