Fig. 1From: A long non-coding RNA HOTTIP expression is associated with disease progression and predicts outcome in small cell lung cancer patientsGene differential expression array analysis and confirmation in SCLC cell lines and FFPE tissues. a & b Differentially expressed HOX genes were involved. c The level of HOTTIP expression in cell lines showed differential expression in 5 SCLC cell lines and the normal human bronchial epithelial cell line (16-HBE). d The level of HOTTIP expression in SCLC clinical tissues and the non-tumoral lung tissues. e Patients with high HOTTIP expression had a significantly poorer prognosis than those with low HOTTIP expression.*, P < 0.05; **, P < 0.01Back to article page
