In vivo synergistic inhibition of CBRH7919 tumor growth by resveratrol and GCV. (A) Subcutaneous tumors were induced in BALB/c mice using CBRH7919^tk and CBRH7919^WT cells mixed at a ratio of 2:3. When tumors reached a diameter of 0.1 mm³, the mice was divided into 6 groups and subjected to drug treatment. (A) The tumors were weighed on the 15^th day after treatment. (B) Tumor volume was measured every 3 days after grouping. Data are shown as mean ± standard error values. *P < 0.05, **P < 0.01 vs. the model group; #P < 0.05 vs. GCV treatment alone.
