Somatic gene mutation signatures predict cancer type and prognosis in multiple cancers with pan-cancer 1000 gene panel.

Most cancers are caused by somatic mutations. Some common mutations in the same cancer type can form a "signature" to specifically predict the prognosis or to distinguish it from other cancers. In this study, 710 somatic cell mutations were identified in 142 cases, including digestive, lung and urogenital cancers, and the digestive cancers were further divided into liver, stomach, intestinal, esophageal and cardia cancer.

[Transfection Efficiency of Ad5F11p-GFP on CIK and NK-92 Cells and Its Influence on Biological Characteristics].

Objective: To study transfection efficiency of Ad5F11p-GFP and its influence on biological characteristics of CIK and NK-92 cells in order to predict the application of Ad5F11p vector in immunotherapy.

Methods: Two kinds of immune cells, cytokine-induced killer (CIK) cells and natural-killer (NK) cell line NK-92 cells, were transfected by Ad5F11p-GFP at different multiplicity of transfection (MOI), and untransfected immune cells were used as negative control. GFP expression was determined by flow cytometry, the cell morphology was observed with microscope, the cell proliferation was analyzed by trypan blue staining, specific cytotoxicity of NK-92 cells was determined by LDH assay.
