As shown in Figure 7B, lnc030 knockdown significantly reduced tumor‐initiating capacity of spheroids in nude mice, and feeding mice with high fat/cholesterol diet (HFD) could rescue the tumor‐initiating capacity of lnc030‐knockdown BCSC; correspondingly, lnc030 overexpression in CSCs increased their tumor‐initiating capacity in mice. This evidence concerns the gene SQLE-DT and neoplasm.
