Fig. 1: Relative expression of HOTTIP and HOXA13 in cell lines and tissues, as well as clinical significance of HOTTIP in SCLC tissues

a Expression of HOTTIP in H69 and H69AR cell lines. b Expression of HOXA13 in H69 and H69AR cell lines. c Expression of HOTTIP in SCLC chemoinsensitive tissues, chemosensitive tissues, and non-cancerous lung tissues counterparts is descending in turn. d Patients with high HOTTIP expression had a significantly poorer prognosis than those with low HOTTIP expression. e Expression of HOXA13 in SCLC chemoinsensitive tissues, chemosensitive tissues, and non-cancerous lung tissues is descending in turn. f Expression of HOXA13 protein is validated in SCLC FFPE tissues by western blot. *P < 0.05; **P < 0.001
