Figure 1. Identification of miRNAs differentially expressed in HNSCC. (A) Expression of miR-141 in HNSCC tissues and adjacent normal tissues detected using real time PCR. (B) Relationship between miR-141 and survival in HNSCC patients. (C) Expression of EGFR in HNSCC tissues and adjacent normal tissues detected using real time PCR. (D) Relationship between EGFR and survival in HNSCC patients. (E) Correlation between expression levels of miR-141 and EGFR in HNSCC. ** P< 0.05 vs. adjacent tissues.
