There are two ways that LINC00173 regulates multidrug resistance in SCLC: one is that LINC00173 performs a chemoresistance-promoting function by regulating glucose metabolism [41], and the other is that LINC00173 promotes the chemoresistance of SCLC by binding with miR-218 to regulate the expression of Etk [28]. The gene discussed is LINC00173; the disease is small cell lung carcinoma.
