Esophageal cancer is one of the most malignant tumors in digestive system, but the pathogenesis of esophageal cancer is still unclear. It has been verified that circular RNAs (circRNAs) play critical roles in development and progression of tumors. However, little research concentrates on the role of circRNAs in the pathogenesis of esophageal cancer. In the present study, we found that circular RNA-RAD23B (circRAD23B) was upregulated in specimens of patients with esophageal cancer. Further investigation revealed that circRAD23B promoted proliferation and invasion of esophageal cancer cells. Next, we identified microRNA-5095 (miR-5095) as a target of circRAD23B, and found that miR-5095 was negatively correlated to the expression of circRAD23B in esophageal cancer. In addition, circRAD23B facilitated expression of PARP2 and AKT2 by sponging miR-5095, which might underlie the growth of esophageal cancer. In summary, these data displayed the crucial role of circRAD23B/miR-5095 regulating PARP2 and AKT2 in esophageal cancer, and provided a novel mechanism in the pathogenesis of esophageal cancer.

Introduction: Several reviews have highlighted that the Patient-Generated Subjective Global Assessment (PG-SGA) is the best diagnostic tool for assessing nutritional status in cancer patients. However, previous meta-analyses summarizing the prevalence of malnutrition and overall survival in patients with gastrointestinal (GI) cancer are quite limited. This study aims to determine the overall prevalence and association between malnutrition, as defined by the PG-SGA, and mortality in adults with GI cancer.

Background: Gamma-glutamyl transferase (GGT) has been shown to have associations with several diseases including cancers. Previous studies have investigated the effect of GGT levels on the gastrointestinal (GI) cancer incidence. We aim to systematically investigate these studies to provide better insights into the interrelationship between GGT and GI cancers.

Background: Esophageal squamous cell carcinoma (ESCC) is a malignant tumor with high morbidity and mortality, and easy to develop resistance to chemotherapeutic agents. Telomeres are DNA-protein complexes located at the termini of chromosomes in eukaryotic cells, which are unreplaceable in maintaining the stability and integrity of genome. Telomerase, an RNA-dependent DNA polymerase, play vital role in telomere length maintain, targeting telomerase is a promising therapeutic strategy for cancer.

Background: Transforming growth factor-β (TGF-β) superfamily plays an important role in tumor progression and metastasis. Activin A receptor type 1C (ACVR1C) is a TGF-β type I receptor that is involved in tumorigenesis through binding to different ligands.

Aim: To evaluate the correlation between single nucleotide polymorphisms (SNPs) of ACVR1C and susceptibility to esophageal squamous cell carcinoma (ESCC) in Chinese Han population.
