Figure 1. CuE mediates the survival of pharynx (Detroit 562) and nasopharyngeal (HONE-1) cancer cells, thereby inhibiting proliferation.

Figure 1

An in vitro study was initiated by treating each of the Detroit 562 and HONE-1 cell lines with increasing doses of CuE (0, 0.625, 1.25 and 2.5 μM) for 24 to 72 hours. The survival of CuE-treated cancer cells was then measured using the MTT method. Results were expressed as a percentage of control, which was considered 100%. All data were reported as the mean (±SEM) of at least three separate experiments. Statistical analysis was performed using a t-test, with significant differences determined at the level of *P < 0.05 versus the control group.
