Fig. 1: Overexpression of TUG1 is associated with poor prognosis in OS patients.

a TUG1 expression in 40 pairs of human OS tissues and adjacent non-tumour tissues was quantified by qRT-PCR. b TUG1 expression levels in OS cell lines were quantified by qRT-PCR. c Overall survival of OS patients with relatively high and low expression of TUG1. d Recurrence-free survival of OS patients with relatively high and low expression of TUG1. ***P < 0.001
