Celecoxib inhibits LLC tumor growth. A total of 2 × 10⁶ LLC cells were implanted into C57BL/6 mice. Mice were fed either control chow (gray bars) or 1,500 mg/kg celecoxib-containing chow (black bars). Tumor volumes were calculated from tumor measurements taken at the indicated day and are represented as the average of each group ± SEM.
