Interestingly, tumor weight was significantly reduced in the xenograft mouse model inoculated with NCOR1-silenced MCF7 cells (p < 0.001) (Figure 1F, upper panel), whereas NCOR1 knockdown did not significantly reduce tumor weight in MDA-MB-231 xenograft mice (Figure 1F, lower panel). Here, NCOR1 is linked to neoplasm.
