Background Enhanced glucose metabolism has been reported in many cancers. Glucose-6-phosphate dehydrogenase (G6PD) is a rate-limiting enzyme involved the pentose phosphate pathway, which maintains NADPH levels and protects cells from oxidative damage. We recently found that low G6PD expression correlates with active tumor immunity. However, mechanism involving immunity remained unclear. Methods conducted vitro studies using G6PD-knocked down malignant melanoma cells, pathway analysis GEO...
Abstract Sera from a number of patients with periodontal diseases were shown to have specific immunoglobulin G (IgG) antibodies against fimbriae and membrane proteins Bacteroides gingivalis , suspected pathogen, by using Western blotting analysis. The sera had strong tendency react fimbriae, or exactly oligomeric structures native β ‐structure rich‐conformation. However, the did not fimbrilin, constituent protein which is denatured sodium dodecyl sulfate.
Anti-PD-1-based immunotherapy is considered a preferred first-line treatment for advanced BRAF V600-mutant melanoma.
