摘 要:Autophagy is a critical cellular homeostatic mechanism,and its dysfunction is linked to invasive breast carcinoma(BRCA).Recently,several omics methods have been applied to explore autophagic regulators in BRCA;however,more reliable and robust approaches for identifying crucial regulators and druggable targets remain to be ***,we report here the results of multi-omics approaches to identify potential autophagic regulators in BRCA,including gene expression(EXP),DNA methylation(MET)and copy number alterations(CNAs)from The Cancer Genome Atlas(TCGA).Newly identified candidate genes,such as SF3 B3,TRAPPC10,SIRT3,MTERFD1,and FBXO5,were confirmed to be involved in the positive or negative regulation of autophagy in ***3 B3 was identified firstly as a negative autophagic regulator,and siRNA/shRNA-SF3 B3 were shown to induce autophagyassociated cell death in in vitro and in vivo breast cancer ***,a novel small-molecule activator of SIRT3,1-methylbenzylamino amiodarone,was discovered to induce autophagy in vitro and in ***,these results provide multi-omics approaches to identify some key candidate autophagic regulators,such as the negative regulator SF3 B3 and positive regulator SIRT3 in BRCA,and highlight SF3 B3 and SIRT3 as new druggable targets that could be used to fill the gap between autophagy and cancer drug development.
