From: The function and mechanism of COX-2 in angiogenesis of gastric cancer cells
Down-regulation of COX-2 suppressed growth of gastric cancer cells in vitro and in vivo. A, The growth rate of the cells was detected using MTT assay as described in "Materials and Methods". The value shown was the mean of three determinations. B, tumorigenicity of the cells in BALB/c nu/nu mice was detected. Each group had at least 6 mice. The volumes of tumors were monitored at the indicated time.
