LINC02544 is overexpressed in lung squamous cell carcinoma patients with lymph node metastasis, and it promotes proliferation, migration, and invasion in vitro by sponging miR-138-5p—a potential target of E2F3 [91]; increased expression of LINC02544 has also been related to in vitro invasion and unfavorable prognosis in breast cancer [92]. The gene discussed is E2F3; the disease is squamous cell lung carcinoma.
