Few risk factors for glioma have been identified other than ionizing radiation. The alkylating agent acrylamide is a compound found in both occupational and the general environment and identified as one of the forty known or suspected neurocarcinogens in animal models. The mutagen sensitivity assay (MSA) has been used to indirectly show reduced DNA repair capacity upon exposure to ionizing radiation in those with glioma compared to controls.

A high proportion of ovarian cancers from women who carry germline mutations in mismatch repair (MMR) genes demonstrate microsatellite instability (MSI). The utility of pre-screening ovarian cancer specimens for MSI to identify potential patients for germline screening for MMR mutations is uncertain. 656 women with malignant ovarian cancer underwent both MSI testing and germline mutation testing for large rearrangements in three MMR genes, MLH1, MSH2 and MSH6.

Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, Duke University Medical Center, Durham, NC, USA. ; Department of Pathology, Duke University Medical Center, Durham, NC, USA.

In infants exposed to maternal stress in utero, phenotypic plasticity through epigenetic events may mechanistically explain increased risk of preterm birth (PTB), which confers increased risk for neurodevelopmental disorders, cardiovascular disease, and cancers in adulthood. We examined associations between prenatal maternal stress and PTB, evaluating the role of DNA methylation at imprint regulatory regions. We enrolled women from prenatal clinics in Durham, NC.

The prodrugs cyclophosphamide (CP) and ifosfamide (IF) each metabolize to an active alkylating agent through a cytochrome P450-mediated oxidation at the C-4 position. Competing with this activation pathway are enzymatic oxidations at the exocyclic α and α' carbons, which result in dechloroethylation of CP and IF. The incidence of oxidation at one position relative to another is believed to be at least one factor underlying the high degree of interpatient variability in both CP and IF pharmacokinetics.

Although single-locus approaches have been widely applied to identify disease-associated single-nucleotide polymorphisms (SNPs), complex diseases are thought to be the product of multiple interactions between loci. This has led to the recent development of statistical methods for detecting statistical interactions between two loci. Canonical correlation analysis (CCA) has previously been proposed to detect gene-gene coassociation.

Increasing vaccine potency through exosome antigen targeting.

Vaccine

November 2011

Duke Comprehensive Cancer Center, Department of Surgery, Duke University Medical Center, Durham, NC 27710, USA.

While many tumor associated antigens (TAAs) have been identified in human cancers, efforts to develop efficient TAA "cancer vaccines" using classical vaccine approaches have been largely ineffective. Recently, a process to specifically target proteins to exosomes has been established which takes advantage of the ability of the factor V like C1C2 domain of lactadherin to specifically address proteins to exosomes. Using this approach, we hypothesized that TAAs could be targeted to exosomes to potentially increase their immunogenicity, as exosomes have been demonstrated to traffic to antigen presenting cells (APC).

CD4+CD25+regulatory T cells (T(reg)) impair anti-tumor and anti-viral immunity. As there are higher T(reg) levels in cancer patients compared with healthy individuals, there is considerable interest in eliminating them or altering their function as part of cancer or viral immunotherapy strategies. The scurfin transcriptional regulator encoded by the member of the forkhead winged helix protein family (FOXP3) is critical for maintaining the functions of T(reg).

Healthcare is experiencing a transformation-perhaps as significant as the publication of the first randomized controlled trial-in the ways in which basic discovery is translated into effective practice. The change is being precipitated by efforts to undergird the healthcare industry with the same transformational capacities from information technology as is afforded to other sectors in the economy. Although the transformation has been slow in materializing, change is expected to accelerate under the stimulating influence of the Health Information Technology for Economic and Clinical Health Act of 2009 and the Patient Protection and Affordable Care Act of 2010.
