The functional potency of natural killer cells in response to IL-2/IL-15/IL-21 stimulation is limited by a concurrent upregulation of Tim-3 in bladder cancer.

For reasons not completely clear, natural killer (NK) cells from tumor patients displayed multiple exhaustion features and could not be completely restored even when the inhibitory signals from the intratumoral environment had ceased to exist. Here, we found that the circulating NK cells from bladder cancer patients presented significantly reduced cytotoxicity than the circulating NK cells from healthy volunteers. This impairment in cytotoxicity resulted in part from an overrepresentation of Tim-3 NK cells in bladder cancer patients.

Different patterns in the prognostic value of age for bladder cancer-specific survival depending on tumor stages.

To compare the pathological features and long-term survival of bladder cancer (BCa) in young patients with elderly counterparts. Using the U.S.

[Spatial variability and evaluation of soil heavy metal contamination in the urban-transect of Shanghai].

Soil heavy metal concentrations along the typical urban-transect in Shanghai were analyzed to indicate the effect of urbanization and industrialization on soil environment quality. Spatial variation structure and distribution of 5 heavy metals (Cu, Cr, Mn, Pb and Zn) in the top soil of urban-transect were analyzed. The single pollution index and the composite pollution index were used to evaluate the soil heavy metal pollution.

RNA interference targeting NRP-1 inhibits human glioma cell proliferation and enhances cell apoptosis.

Neuropilin-1 (NRP-1) is a non-tyrosine kinase receptor for vascular endothelial growth factor (VEGF) that was recently found to play a role in tumor functions. Previous studies demonstrated that NRP-1 was overexpressed in a number of human tumors, including glioblastoma (GBM). However, the role of NRP-1 in glioma progression has yet to be adequately elucidated.

Variants in the insulin-degrading enzyme gene are associated with metabolic syndrome in Chinese elders.

Metabolic syndrome (MetS) is a cluster of metabolic abnormalities sharing potential common underlying mechanisms. Insulin-degrading enzyme (IDE) plays a primary role in insulin degradation and cellular insulin processing and therefore affects glucose and lipid metabolism. Genetic association studies have been focused on the relationship between the IDE gene and the development of MetS.

Association between the PDE4D gene and ischaemic stroke in the Chinese Han population.

Recent findings suggests that PDE4D (gene encoding phosphodiesterase 4D) is a stroke-related gene in the Icelandic population, but it is still very controversial as to whether it is a susceptible gene for stroke in other populations. In the present study, we attempted to explore the role of the gene in the pathogenesis of stroke in the Chinese Han population of eastern China. A total of 649 ischaemic stroke patients and 761 unrelated control individuals with no history of stroke or transient ischaemic attack were examined in a case-control study.
