Odd-skipped related transcription factor 1 (OSR1) suppresses tongue squamous cell carcinoma migration and invasion through inhibiting NF- κB pathway.

Odd-skipped related transcription factor 1 (OSR1) suppresses tongue squamous cell carcinoma migration and invasion through inhibiting NF-κB pathway. Eur J Pharmacol. 2018 Sep 19;: Authors: Chen W, Zou A, Zhang H, Fu X, Yao F, Yang A Abstract Tongue squamous cell carcinoma (TSCC) is the most common cancers of oral, owing to the high invasive and metastatic ability, patients with TSCC have poor prognosis, it's important to explore the regulatory mechanism of TSCC invasion and metastasis. Previous studies suggest OSR1 suppresses the progression of gastric cancer and renal cell carcinoma, but its role in TSCC hasn't been studied. Here, we found OSR1 was downregulated in TSCC cells and specimens, Transwell and 3D spheroid invasion assay suggested OSR1 overexpression inhibited TSCC cell migration and invasion, while its knockdown promoted TSCC cell migration and invasion. Mechanism analysis found OSR1 expression was negatively correlated with NF-κB pathway and its targets. Western blot and NF-κB activity analysis suggested OSR1 inhibited NF-κB activity. Double inhibition of OSR1 and NF-κB significantly inhibited TSCC cell migration and invasion. These findings suggested OSR1 inhibited TSCC cell migration and invasion through inhibiting NF-κB pathway. PMID: 30244004 [PubMed - as supplied by publisher]
