Project description:We herein examine the transciptioal alteration of a single cell derived MDA-MB-231 subline,SCP21. By retrieving tumor cells inoculated in different sites, we generated multiple mammary fat pad tumor, lung metastases or bone metastasis derived SCP21 sublines. RNA-sequencing uncovered the decreased expression of EZH2 target genes in bone metastases derived cells compared other organ entrained and parental SCP21 cells , suggesting enhanced EZH2 activity. Moreover, such phenotype is reversible upon in vitro culture. As a positive control, bone derived cells were also treated with EZH2 inhibitor, EPZ011989, to confirm the decreased level of EZH2 target genes upon EZH2 inhibition.
