At the end of the study (day 32), tumor size of SRC‐3 knockdown group (309 ± 34 mm3, 293 ± 27 mm3) was only 43% and 48% of the control group (715 ± 51 mm3, 616 ± 27 mm3), respectively, and tumor weight of SRC‐3‐silenced group (229 ± 22 mg, 201 ± 14 mg) was also significantly lower than the scramble control group (537 ± 82 mg, 466 ± 61 mg), respectively (Fig. 5). Here, NCOA3 is linked to neoplasm.
