CDKN1C and neoplasm: While the small sample number created by splitting of the treatment group precludes statistically significant comparisons between the two groups, it is compelling that the tumors with the greatest increases in CDKN1C and MYOG as measured by RT‐qPCR (Fig. S12C,D), suggesting they are the most differentiated, also had the smallest endpoint tumor volume (Fig. S12E).
