Meeting report on the first Sino-Dutch symposium on oncology

On October 31, 2015, the first Sino-Dutch symposium on oncology was organized in Guangzhou (China). The symposium revealed similarities between Chinese and Dutch efforts to improve the care of tumor patients and to create enhanced insight into the nature of cancers. In particular, it became evident for some types of cancer that immunotherapy should focus on counteracting interleukin-17-associated immunity and targeting cancer stroma. Targeting specific cancer microenvironment and stroma also opens new therapeutic options, including the use of radio-active theranostics and live tumor imaging-guided surgeries

Drug Discovery in Liver Disease Using Kinome Profiling

The liver is one of the most important organs, playing critical roles in maintaining biochemical homeostasis. Accordingly, disease of the liver is often debilitating and responsible for un-told human misery. As biochemical nexus, with kinases being master regulators of cellular biochem-istry, targeting kinase enzymes is an obvious avenue for treating liver disease. Development of such therapy, however, is hampered by the technical difficulty of obtaining comprehensive insight into hepatic kinase activity, a problem further compounded by the often unique aspects of hepatic kinase activities, which makes extrapolations from other systems difficult. This consideration prompted us to review the current state of the art with respect to kinome profiling approaches towards the hepatic kinome. We observe that currently four different approaches are available, all showing significant promise. Hence we postulate that insight into the hepatic kinome will quickly increase, leading to rational kinase-targeted therapy for different liver diseases.</p

Opportunities for conventional and in situ cancer vaccine strategies and combination with immunotherapy for gastrointestinal cancers, a review

Survival of gastrointestinal cancer remains dismal, especially for metastasized disease. For various cancers, especially melanoma and lung cancer, immunotherapy has been proven to confer survival benefits, but results for gastrointestinal cancer have been disappointing. Hence, there is substantial interest in exploring the usefulness of adaptive immune system education with respect to anti-cancer responses though vaccination. Encouragingly, even fairly non-specific approaches to vaccination and immune system stimulation, involving for instance influenza vaccines, have shown promising results, eliciting hopes that selection of specific antigens for vaccination may prove useful for at least a subset of gastrointestinal cancers. It is widely recognized that immune recognition and initiation of responses are hampered by a lack of T cell help, or by suppressive cancer-associated factors. In this review we will discuss the hurdles that limit efficacy of conventional cancer therapeutic vaccination methods (e.g., peptide vaccines, dendritic cell vaccin

Helicobacter pylori pathogenicity factors related to gastric cancer

_Background_. Although the causal relationship between Helicobacter pylori infection and the development of gastric cancer is firmly established, the exact nature of the pathogenicity factors of H. pylori that predispose to gastric oncogenesis remains incompletely characterized. We investigated the association between H. pylori virulence genotypes and disease in a well-characterized cohort consisting of 109 H. pylori isolates from gastric biopsies originating from patients. _Methods_. The prevalence of genotype was assessed by PCR and related to clinical histopathological parameters. _Results_. The relation of babA2 and babB negative and iceA1 positive genotype as a single genotype and the development of cases to GC was statistically significant (P<0.001). The cagE, cagA, and iceA1 were found more commonly in patients with GC as compared with the other groups. The relation of the presence of iceA1 and the development of cases to GC was statistically significant (P=0.008), bu
