Abstract

The present study aimed to investigate the role of partner of NOB1 homolog (PNO1) in esophageal cancer (EC). The expression levels of PNO1 in EC were primarily analyzed using data obtained from databases. PNO1 expression was also knocked down in EC cells (Eca‑109 and TE1) to determine the biological effects of PNO1 on tumorigenesis in vitro and in vivo. In addition, possible downstream targets of PNO1 in EC were identified. The expression levels of PNO1 were upregulated in the tumor tissues compared with that noted in normal tissues. Moreover, the knockdown (KD) of PNO1 suppressed cell proliferation, migration and invasion, and promoted cell apoptosis (P<0.05). Furthermore, the protein expression levels of AKT1, Twist, Myc, mTOR, matrix metalloproteinase 2 (MMP2), nuclear factor (NF)‑κB p65 and β‑catenin 1 (CTNNB1) were downregulated following the KD of PNO1 in Eca‑109 cells (P<0.05). In addition, the overexpression of CTNNB1 reversed the effects of PNO1 KD in Eca‑109 cells (P<0.05). In conclusion, the findings of the present study suggest that PNO1 promotes EC progression by regulating AKT1, Twist, Myc, mTOR, MMP2, NF‑κB p65 and CTNNB1 expression.
