AIM: The goal of the present study was to further refine how polygenic risk scores may be used in a large population and to quantify the transmission of risk score through generations. METHODS: Allele frequencies from the 1000 Genomes data for 159 single nucleotide polymorphisms associated with breast cancer risk were used. A breast cancer risk score was calculated among 100,000 people. Choosing two "parents" and the alleles they transmit at random, 100,000 "daughters" were simulated...

All intact cells, and their organelles, are surrounded by a ∼30 Å hydrophobic film that typically separates the interior from the environment. This film is composed of lipid bilayers that form from a pool of structurally highly diverse, amphipathic lipids. The specific composition and nature of these lipids strongly contributes to many different processes in the cell by influencing membrane structures, membrane protein sorting and functionalities. In this review, we discuss strategies to alter membrane lipid compositions of organelles and plasma membranes in different organisms, focusing on microbial cells...

The development and progression of a tumor depends on the close interaction of malignant cells and the supportive and suppressive tumor microenvironment. Paracrine signaling enables tumor cells to shape the surrounding tissue in order to decrease recognition by the immune system, attract blood vessels to fuel growth, change metabolic programs and induce wound healing programs. In this study, we investigate the role of the platelet-derived growth factor (PDGF) family members PDGFA, PDGFB, PDGFC and PDGFD and their cognate tyrosine kinase receptors PDGFRA and PDGFRB, using publicly available data from The Cancer Genome Atlas and the Human Protein Atlas...

Indoleamine 2,3-dioxygenase 1 (IDO1) activity links to immune escape of cancers. Inhibition of IDO1 provides a new approach for cancer treatment. Most clinical IDO1 drugs show marginal efficacy as single agents. On basis of molecular docking and pharmacophore modelling, a novel inhibitor Roxyl-WL was discovered with a half maximal inhibitory concentration (IC50) value of 1 nM against IDO1 and 10-100-fold increased potent activity compared with IDO1 drugs in clinical trials. Roxyl-WL displayed excellent kinase spectrum selectivity with no activity out of the 337 protein kinases...

Despite the therapeutic usefulness of near-infrared irradiation (NIR)-induced potent photothermal effects (PTE) and photodynamic effects (PDE), they inevitably damage normal tissues, often posing threat to life when treating tumors adjacent to key organs or major blood vessels. In this study, the frequently overlooked, "weak" PTE and PDE (no killing capability) are employed to synergize chemotherapy against multidrug resistance (MDR) without impairing normal tissues. An NIR-responsive nanosystem, gold (Au)-nanodot-decorated hollow carbon nanospheres coated with hyaluronic acid, is synthesized as a doxorubicin (DOX) carrier with excellent photothermal and photodynamic properties...

Glioblastoma (GBM) is the most frequent and aggressive type of brain tumor. There are limited therapeutic options for GBM so that new and effective agents are urgently needed. Euphol is a tetracyclic triterpene alcohol, and it is the main constituent of the sap of the medicinal plant Euphorbia tirucalli. We previously identified anti-cancer activity in euphol based on the cytotoxicity screening of 73 human cancer cells. We now expand the toxicological screening of the inhibitory effect and bioactivity of euphol using two additional glioma primary cultures...

PURPOSE: Head and neck squamous cell carcinoma (HNSCC) is one of common cancers worldwide. Positron emission tomography (PET) with 2-deoxy-2-[18 F]fluoro-D-glucose ([18 F]FDG) is increasingly used for diagnosing and staging, as well as for monitoring of treatment of HNSCC. PET parameters like maximum and mean standard uptake values (SUVmax , SUVmean ) can predict the behavior of HNSCC. The purpose of this study was to analyze possible associations between these PET parameters and clinically relevant histopathological features in patients with HNSCC...

Radon and thoron progenies in Dutch dwellings cause ~400 cases of lung cancer per year. Some 30% of the risk is due to thoron progeny, which demonstrates that the influence of thoron progeny is much larger than previously anticipated. This was concluded from a national survey in 2500 Dutch dwellings, built since 1930. Radon concentrations (15.6 ± 0.3 Bq m-3 on average) are correlated to type of dwelling, year of construction, ventilation system, location (soil type) and smoking behaviour of inhabitants. The survey data support the establishment of a comparatively low national reference level for radon in dwellings in the Netherlands of 100 Bq m-3, in line with recommendations by WHO and ICRP...

Controversy still exists as to whether a high body mass index (BMI) has any impact on the long-term survival of esophageal cancer patients treated with curative esophagectomy. Therefore, we conducted this propensity score-matched (PSM) study to explore the prognostic value of high BMI in Chinese patients with lower thoracic esophageal adenocarcinoma for the first time. We retrospectively collected data of patients with lower thoracic esophageal adenocarcinoma who underwent curative esophagectomy in our department from January 2009 to December 2016...

MicroRNAs (miRNAs) are ∼22-nt molecules exerting control of protein expression in cancer tissues. The current study determined the full spectrum of miRNA dysregulation in freshly isolated human colon or rectal cancer biopsies as well as in controls of healthy adjacent tissue (total of n = 100) using an Illumina sequencing technology. In this work, we aimed to identify miRNAs that may serve as future marker to discern between these two subtypes. DESeq2 analysis revealed 53 significantly dysregulated miRNAs in colon cancer, 67 miRNAs in rectal cancer, and 97 miRNAs in both at a P adj value < 0...

Background: Natural killer (NK) cells are lymphocytes of the innate immune system that have potent cytotoxic activity against tumor cells. NK cell recognition and activity towards cancer cells are regulated by an integrated interplay between numerous inhibitory and activating receptors acting in concert to eliminate tumor cells expressing cognate ligands. Despite strong evidence supporting the role of NK cells in breast cancer (BC) control, BC still develops and progresses to form large tumors and metastases...
