In regards to MDA-MB-231 mammary tumours, there was no statistically significant overall difference in the growth of MDA-MB-231 tumours with SOCS7 knockdown compared to that of the transfection control group, even though it appears that the control group tumours have grown marginally bigger (P = 0.057 by two-way ANOVA). This evidence concerns the gene SOCS7 and breast cancer.
