Cell-Free DNA as a prognostic and predictive biomarker in resectable distal common bile duct cancer.
Cell-free DNA (cfDNA) as an oncological biomarker has drawn much attention in recent years, but very limited effort has been made to investigate the prognostic values of cfDNA in distal common bile duct (CBD) cancer. ⋯ Circulating cfDNA levels play a significant role in predicting the prognosis and survival outcome for resectable distal CBD cancer. Furthermore, acting as a promising liquid biopsy, cfDNA could serve as a prognostic and predictive biomarker in combination with current conventional markers to improve diagnostic and prognostic efficacy.

Aberrant glycosylation performed by glycosyltransferases is a leading cause of gastric cancer (GC). Protein O-fucosyltransferase 1 (POFUT1) expression is increased in GC specimens and cells. In this study, the biological effects and mechanisms of POFUT1 underlying the development of GC were investigated. ⋯ These observations indicated that POFUT1 promoted GC development through activation of Notch and Wnt signaling pathways, which depended on the parafibromin-NICD1-β-catenin complex. This work provides new evidence for the further diagnosis and treatment of GC.
