In addition, many studies have shown that CC tumor tissue has a higher copper levelsthan normal tissue (43).In our study, it was found that after overexpression of lnc-CNNM3-DT, intracellular copper levels, and LIAS expression were decreased, cell proliferation, migration, and migration ability were inhibited, and apoptosis was increased. The gene discussed is LIAS; the disease is neoplasm.
