Fig. 6From: A long non-coding RNA HOTTIP expression is associated with disease progression and predicts outcome in small cell lung cancer patientsHOTTIP may be involved in SCLC progression partly by regulating EZH1. a Differential expression of EZH1 in SCLC cell lines and 16-HBE cell line by RT-qPCR. b Differential expression of EZH1 in SCLC tissues and non-tumoral lung tissues by RT-qPCR. c HOTTIP may positively regulate expression of EZH1 protein in xerograft tumor tissues by immunohistochemistry technique. *, P < 0.05Back to article page
