DNA modifications such as 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) are epigenetic marks known to affect global gene expression in mammals. Given their prevalence in the human genome, close correlation with gene expression and high chemical stability, these DNA epigenetic marks could serve as ideal biomarkers for cancer diagnosis. Taking advantage of a highly sensitive and selective chemical labeling technology, we report here the genome-wide profiling of 5hmC in circulating cell-free DNA (cfDNA) and in genomic DNA (gDNA) of paired tumor and adjacent tissues collected from a cohort of 260 patients recently diagnosed with colorectal, gastric, pancreatic, liver or thyroid cancer and normal tissues from 90 healthy individuals...

Calcineurin inhibitors (CNIs) are frequently given at a reduced dose in combination with mycophenolate mofetil (MMF) to avoid nephrotoxicity, but the optimal reduction in CNI dose has not been established. In this prospective, open-label, multicenter study, liver transplant recipients with chronic renal dysfunction who were administered a CNI-based immunosuppressive regimen were included in the intent-to-treat (ITT) population. The primary endpoint was declination in renal function, which was defined as a ≥ 20% decrease in the glomerular filtration rate during the year following regimen adjustment...

The viral transforming proteins E6 and E7 make human papilloma virus positive (HPV+) malignancies an attractive target for cancer immunotherapy. However, therapeutic vaccination exerts limited efficacy in the setting of advanced disease. We designed a strategy to induce substantial specific immune responses against multiple epitopes of E6 and E7 proteins based on an attenuated transgene from HPV serotypes 16 and 18 that is incorporated into MG1-Maraba virotherapy (MG1-E6E7). Mutations introduced to the transgene abrogate the ability of E6 and E7 to perturb p53 and retinoblastoma, respectively, while maintaining the ability to invoke tumor-specific, multi-functional CD8+ T-cell responses...

BACKGROUND: Resistance to chemotherapy is a major obstacle in the treatment of human hepatocellular carcinoma (HCC). Despite playing an important role in chemoprevention, nuclear factor erythroid 2-related factor 2 (NRF2) also contributes to chemo- and radio-resistance. The current study focusses on camptothecin as a novel NRF2 inhibitor to sensitise HCC to chemotherapy. METHODS: The expression and transcriptional activity of NRF2 in human HCC biopsies and camptothecin-treated culture cells were determined using immunostaining, western blot, reverse-transcription quantitative real-time PCR (RT-qPCR) and luciferase reporter assay...

Though evidence-based treatments have been recommended for breast cancer, underuse of the treatments was still observed. To certain extent, patients' access to care, which can be enhanced by increasing the coverage of health insurance, could account for the current underuse in recommended care. This study aimed to examine the association between different proportions of reimbursement and quality of recommended breast cancer care, as well as length of hospital stay. In this retrospective study, 3669 patients diagnosed with invasive breast cancer between 1 June, 2011 and 30 June, 2013 were recruited...

OBJECTIVE: β-alanine (BA) is a nonproteogenic amino acid that combines with histidine to form carnosine. The amount taken orally in individual doses, however, is limited due to symptoms of paresthesia that are associated with higher doses. The use of a sustained-release formulation has been reported to reduce the symptoms of paresthesia, suggesting that a greater daily dose may be possible. The purpose of the present study was to determine whether increasing the daily dose of BA can result in a similar increase in muscle carnosine in a reduced time...

RATIONALE: Eosinphilic gastroenteritis (EG) is a gastrointestinal disorder characterized by eosinophilic infiltration with various manifestations. The diagnosis is usually confirmed by an endoscopic biopsy, which is considered a safe and routine procedure for the majority. PATIENT CONCERNS: We report a 54-year-old male who was presented with intermittent periumbilical pain and melena, and only revealed verrucous gastritis by endoscopy. DIAGNOSES: The patient's condition worsened two days after the endoscopic biopsy, and another endoscopy found hematoma and ulcers in upper gastrointestinal tract...

Colorectal cancer (CRC) is one of the leading causes of cancer deaths in China. A standard practice in treating metastatic CRC (mCRC) is to predict benefits of the anti-EGFR monoclonal antibody treatment based on the somatic mutation spectrum. Because metastatic samples are difficult to obtain clinically, primary tumors are normally used instead. However, due to the genetic heterogeneity between primary and paired metastatic tumors, primary site biopsy always underrepresents the mutational landscape of metastatic sites...

There is limited data describing endothelial cell (EC) gene expression between aneurysms and arteries partly because of risks associated with surgical tissue collection. Endovascular biopsy (EB) is a lower risk alternative to conventional surgical methods, though no such efforts have been attempted for aneurysms. We sought (1) to establish the feasibility of EB to isolate viable ECs by fluorescence-activated cell sorting (FACS), (2) to characterize the differences in gene expression by anatomic location and rupture status using single-cell qPCR, and (3) to demonstrate the utility of unsupervised clustering algorithms to identify cell subpopulations...
