Recently, studies have been suggested that H3K27me3 is implicated with maintenance of cancer stem cells (CSCs), however, the roles of H3K27me3 in Breast cancer stem cells (BCSCs) remain poorly investigated. Here we explore the functionallities of H3K27me3 on BCSCs, we identify H3K27me3 as a neg. modulator of BCSCs and suggest GSKJ4 is a promising drug targeting BCSCs. We show that the H3K27me3 level is decreased in mammosphere-derived BCSCs. In breast cancer cells, we demonstrate that GSKJ4 could markedly inhibit the proliferation. Strikingly, we show that GSKJ4 could effectively suppress BCSCs including expansion, self-renewal capacity, and the expression of stemness-related markers. Addnl., our xenograft model confirms that GSKJ4 is able to effectively inhibit the tumorigenicity of MDA-MB-231. Mechanistically, the inhibition effects of GSKJ4 on BCSCs are via inhibiting demethylases JMJD3 and UTX with methyltransferase EZH2 unchanged, which enhances H3K27me3 level. H3K27me3 activating leads to reduction of BCSCs expansion, self-renewal and global level of stemness factors. Collectively, our results provide strong supports that H3K27me3 exerts a suppressive influence on BCSCs and reveal that GSKJ4 is capable to be a prospective agent targeting BCSCs. This study involved multiple reactions and reactants, such as Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate (cas: 1373423-53-0Safety of Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate).
Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate (cas: 1373423-53-0) belongs to pyrimidine derivatives. The pyrimidine derivatives can easily interact with enzymes, genetic materials, and bio components within the cell. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.Safety of Ethyl 3-((6-(4,5-dihydro-1H-benzo[d]azepin-3(2H)-yl)-2-(pyridin-2-yl)pyrimidin-4-yl)amino)propanoate
