Background:The p17 protein of avian reovirus (ARV) encoded by the S1 gene is a CRM1-independent nucleocytoplasmic shuttling protein that continuously shuttles between the nucleus and cytoplasm. Results: ARV p17 protein triggers PTEN, AMPK, and PKR/eIF2␣ signaling pathways to induce autophagy. Conclusion: ARV p17 protein functions as a positive regulator of autophagy. Significance: This is the first evidence that ARV p17 protein triggers autophagic pathways to induce autophagy-enhancing virus replication.

In additional to tumor-nodes-metastasis (TNM) staging system, patient sex and age, tumor location, cell type, and differentiation were independent prognostic factors. We recommend incorporation of these factors to subclassify lung cancer patients.

Endoscopic tumor length could have a significant impact on both the OS and DFS of patients with resected ESCC and may provide additional prognostic value to the current tumor, node, and metastasis staging system before patients receive any cancer-specific treatment.
