Abstract Therapeutic checkpoint antibodies blocking programmed death receptor 1/programmed ligand 1 (PD-L1) signaling have radically improved clinical outcomes in cancer. However, the regulation of PD-L1 expression on tumor cells is still poorly understood. Here we show that intratumoral copper levels influence cancer cells. Deep analysis The Cancer Genome Atlas database and tissue microarrays showed strong correlation between major influx transporter (CTR-1) across many cancers but not...
Histone chaperone FACT acts in a positive feedback loop with MYCN and is therapeutic target neuroblastoma.
There is no effective treatment for the cardiomyopathy of most common autosomal recessive ataxia, Friedreich ataxia (FA). This disease due to decreased expression mitochondrial protein, frataxin, which leads alterations in iron (Fe) metabolism. The identification potentially toxic Fe deposits FA suggests plays a role its pathogenesis. Studies using muscle creatine kinase (MCK) conditional frataxin knockout mouse that mirrors have demonstrated deletion alters cardiac Indeed, there are...
Iron is critical for cellular proliferation and its depletion leads to a suppression of both DNA synthesis global translation. These observations suggest that iron may trigger "stress response". A canonical response cells stress the formation granules, which are dynamic cytoplasmic aggregates containing stalled pre-initiation complexes function as mRNA triage centers. By differentially prioritizing translation, granules allow continued selective translation proteins. Although multi-subunit...
Metastatic cancer cells exploit Epithelial-mesenchymal-transition (EMT) to enhance their migration, invasion, and resistance treatments. Recent studies highlight that elevated levels of copper are implicated in progression metastasis. Clinical trials using chelators associated with improved patient survival; however, the molecular mechanisms by which depletion inhibits tumor metastasis poorly understood. This remains a major hurdle clinical translation chelators. Here, we propose chelation...
It is becoming increasingly evident that single-locus effects cannot explain complex multifactorial human diseases like cancer. We applied the multi-factor dimensionality reduction (MDR) method to a large cohort study on gene–environment and gene–gene interactions. The (case-control nested in EPIC cohort) was established investigate molecular changes genetic susceptibility relation air pollution environmental tobacco smoke (ETS) non-smokers. have analyzed 757 controls 409 cases with bladder...
Iron deficiency affects 500 million people, yet the molecular role of iron in gene expression remains poorly characterized. In addition, alterations global after chelation remain unclear and are important to assess for understanding pathology biological effects chelators. Considering this, we assessed effect on whole genome two chelators (desferrioxamine 2-hydroxy-1-napthylaldehyde isonicotinoyl hydrazone) that have markedly different permeability properties. Sixteen genes were significantly...
Iron plays a crucial part in proliferation while iron deficiency results G1/S arrest, DNA damage, and apoptosis. However, the precise role of cell cycle control remains unclear. We showed that depletion using chelators, desferrioxamine (DFO), or 2-hydroxy-1-napthylaldehyde isonicotinoyl hydrazone (311), increased mRNA levels growth arrest damage 45α gene, GADD45α (Darnell, G. Richardson, D. R. (1999) Blood 94, 781–792). In this study, we examined effect on up-regulating GADD family members...
The (32)P-post-labelling assay has emerged as a major tool for detecting bulky DNA adducts in subjects exposed to carcinogens, especially aromatic compounds. However, the protocol still requires use of high amounts radioactivity, i.e. 25-50 muCi per sample, an obstacle that limits its large studies. characterization measured is also limited. Methodological improvements and increased adduct are necessary make this capable achieving higher throughput. A new was tested ensure efficient...

We postulated that...
Pediatric high grade gliomas (HGG) are primary brain malignancies that result in significant morbidity and mortality. One of the challenges their treatment is inter- intra-tumoral heterogeneity. Precision medicine approaches have potential to enhance diagnostic, prognostic and/or therapeutic information. In this case study we describe molecular characterization a pediatric HGG use an integrated approach based on genomic, vitro vivo testing identify actionable targets options. Molecular...
Given the strong clinical evidence that copper levels are significantly elevated in a wide spectrum of tumors, homeostasis is considered as an emerging target for anticancer drug design.Monitoring vivo therefore paramount importance when assessing efficacy copper-targeting drugs.Herein, we investigated activity compound Dextran-Catechin by developing [ 64 Cu]CuCl2 PET imaging protocol to monitor its effect on tumors.Methods: Protein expression transporter 1 (CTR1) tissue microarrays...
