Fig. 1. lncRNA FOXD2-AS1 were upregulated in LSCC patients with chemotherapy resistance and its high expression level was correlated with patients’ poor prognostics.

a FOXD2-AS1 mRNA expression in primary head and neck squamous cell carcinoma (HNSC) tissues (tumor) and matched normal tissues (normal) from UALCAN webserver. b, c FOXD2-AS1 mRNA expression in primary HNSC tissues from patients with different clinical stages and tumor grades from UALCAN webserver, respectively. df Prognostic value of FOXD2-AS1 expression in HNSC patients by using online Kaplan–Meier Plotter analysis. d Overall survival (OS) of 259 stage IV HNSC patients according the FOXD2-AS1 status. The median value of FOXD2-AS1 expression levels in these 259 tissues was used to stratify the high and low expression levels of FOXD2-AS1. e, f OS of 499 HNSC patients according the FOXD2-AS1 status. The median value and the best cutoff value of FOXD2-AS1 expression levels in these 499 tissues was used to stratify the high and low expression levels of FOXD2-AS1, respectively. g Real-time PCR analysis of FOXD2-AS1 expression in 24 primary laryngeal squamous cancer tissues and matched adjacent normal tissues. h FOXD2-AS1 expression were significantly increased in 21 out of 24 cases of tumor comparing with paired normal tissues. i FOXD2-AS1 mRNA expression in primary HNSC tissues from patients with different clinical stages. j FOXD2-AS1 mRNA expression in primary HNSC tissues from patients with different relapse status. Transcript levels were normalized to GAPDH expression. *P < 0.05, **P < 0.01, and ***P < 0.001.
