The LeXis expression is increased in OS. A. Expression of lncRNA LeXis was measured in 60 pairs of OS cancerous tissues (C) and adjacent noncancerous bone tissues (NC) using qPCR. B. Expression of lncRNA LeXis was detected in five OS cell lines (KHOS, 143b, LM7, U2OS and MG-63) and normal osteoblast cells (NHOst) using qPCR (*P < 0.05). C. Kaplan-Meier survival curve and log-rank test were used to evaluate the association of LeXis expression with overall survival rate. Patients were segregated into LeXis-high group and LeXis-low according to the median of LeXis expression in OS tissues.
