Abstract Background Glucose-6-phosphate dehydrogenase (G6PD), elevated in tumor cells, catalyzes the first reaction pentose-phosphate pathway. The regulation mechanism of G6PD and pathological change human melanoma growth remains unknown. Methods HEM (human epidermal melanocyte) cells with wild-type gene (A375-WT), deficiency (A375-G6PD∆), cDNA overexpression (A375-G6PD∆-G6PD-WT), mutant (A375-G6PD∆-G6PD-G487A) were subcutaneously injected into 5 groups nude mice. Expressions G6PD, STAT3,...

Abstract Olaparib is an FDA-approved PARP inhibitor (PARPi) that has shown promise as a synthetic lethal treatment approach for BRCA-mutant castration-resistant prostate cancer (CRPC) in clinical use. However, emerging data have also even cells may be resistant to PARPi. The mechanistic basis these drug resistances poorly understood. Polo-like kinase 1 (Plk1), critical regulator of many cell-cycle events, significantly elevated upon castration mice carrying xenograft tumors. Herein, by...

[18F]fluoro‑2‑deoxyglucose (FDG) positron emission tomography (PET)‑computed (CT) is a functional imaging modality based on glucose metabolism. The association between the maximum standardized uptake value (SUVmax) from 18F‑FDG PET‑CT scanning and epidermal growth factor receptor (EGFR) mutation status has, to best of our knowledge, not previously been fully elucidated, potential mechanisms by which EGFR mutations alter FDG are largely unknown. A total 157 patients who were pathologically...

Adenomyoepithelioma (AME) is a relatively rare type of tumor formed by the coordinated proliferation glandular epithelial cells and myoepithelial cells. Clinically, most them are benign, while malignant ones extremely rare. Malignant breast adenomyoepithelioma somewhat invasive may recur locally or metastasize distantly through vascular pathway. However, reports on axillary lymph node metastasis scarce. In this case, we present an instance with metastasis. By combining previous studies,...

Fluence-to-dose conversion coefficients are fundamental ingredients to calculate astronaut radiation dose in space. For this purpose, the for isotropic provided by International Commission on Radiological Protection Publication 123 (ICRP123) widely used. Understanding uncertainties these is important a precise calculation of dose. In work, we present systematic study unshielded calculated means GEANT4 Monte Carlo simulation toolkit and human voxel phantoms defined ICRP 110. Four physics...

To understand the effects of endophytic fungus Y118 on physiological characteristics Zanthoxylum nitidum (Roxb.) DC after co-culture with its host nitidum, we measured plant growth index (dry root weight) at different stages using solid fermentation medium containing Y118. Physiological and biochemical indexes (defensive enzyme activity) were determined by chromatographic analysis contents chloride chelidonine, main active ingredients in root. At 3, 9 12 months, dry weight treatment group...

Since altered energy metabolism is a hallmark of cancer, many drugs targeting metabolic pathways are in active clinical trials. The tumor suppressor p53 often inactivated either through downregulation protein or loss-of-function mutations. As such, stabilization considered as one promising approach to treat those cancers carrying wild type (WT) p53. Herein, SIRT1 inhibitor Tenovin-1 and polo-like kinase 1 (Plk1) BI2536 were used stabilize We found that both Tennovin-1 increased the...

The purpose of this study was to compare the quality life (QoL) stage II nasopharyngeal carcinoma (NPC) patients treated with radiotherapy (RT) versus concurrent chemoradiotherapy (CCRT). In a cross-sectional study, these were RT (n = 55) or CCRT 51) between June 2008 and 2013. For all subjects, disease-free survival more than 3 years. QoL assessed using European Organization for Research Treatment Cancer Quality Life Questionnaire-Core 30 (EORTC QLQ-C30) questions Head Neck 35 QLQ-H&N35)...
