In addition, lnc030 or SQLE knockdown attenuated tumor growth, tumor size, and tumor weight of xenograft in vivo; cholesterol feeding fueled tumor growth in mice xenografts injected with lnc030‐knockdown or SQLE‐silenced breast cancer cells; and ectopic lnc030 in breast cancer cells notably facilitated tumor growth, and knockdown of SQLE in lnc030‐overexpressing tumor cells attenuated tumor growth (Figure 7C–E). Here, SQLE-DT is linked to breast carcinoma.
