Veliparib with temozolomide or carboplatin/paclitaxel versus placebo with carboplatin/paclitaxel in patients with BRCA1/2 locally recurrent/metastatic breast cancer: randomized phase II study.

Background: Homologous recombination defects in BRCA1/2-mutated tumors result in sensitivity to poly(ADP-ribose) polymerase inhibitors, which interfere with DNA damage repair. Veliparib, a potent poly(ADP-ribose) polymerase inhibitor, enhanced the antitumor activity of platinum agents and temozolomide in early phase clinical trials. This phase II study examined the safety and efficacy of intermittent veliparib with carboplatin/paclitaxel (VCP) or temozolomide (VT) in patients with BRCA1/2-mutated breast cancer.

Evolution of Corneal Graft Survival Over a 30-Year Period and Comparison of Surgical Techniques: A Cohort Study.

Design: Cohort study.

Methods: setting: Regional center (Besançon University Hospital, France).

Aberrant dendritic cell function conditions Th2-cell polarization in allergic rhinitis.

Background: Myeloid (m) and plasmacytoid (p) dendritic cells (DCs) regulate immune responses to allergens, whereas it remains unclear whether abnormal DC function characterizes patients with airway allergy and whether putative dysfunction exists only in target organs. To evaluate DC function from patients with allergic rhinitis (AR), we assessed nasal, cutaneous as well as blood DCs after in vivo and in vitro allergen challenge, respectively.

Methods: DCs were immunostained in nasal and skin tissues, and cytokine expression was assessed by dual immunofluorescence.

Generation of myometrium-specific Bmal1 knockout mice for parturition analysis.

Human and rodent studies indicate a role for circadian rhythmicity and associated clock gene expression in supporting normal parturition. The importance of clock gene expression in tissues besides the suprachiasmatic nucleus is emerging. Here, a Bmal1 conditional knockout mouse line and a novel Cre transgenic mouse line were used to examine the role of myometrial Bmal1 in parturition.

Dual effect of neutrophils on pIgR/secretory component in human bronchial epithelial cells: role of TGF-beta.

Neutrophils have a dual affect on epithelial pIgR/SC, the critical receptor for transcellular routing of mucosal IgA, but mechanisms of pIgR/SC upregulation remain elusive. Requirements of cytokine, redox, and signalling pathways for pIgR/SC production were assessed in human bronchial epithelial (Calu-3) cells cocultured with increasing numbers of blood neutrophils. Increased SC production was observed after incubation for 48 hrs with intermediate neutrophil numbers (1.

Preventing preterm birth: the past limitations and new potential of animal models.

The high rate of preterm birth in the USA and many other countries is a potential target for improving children's immediate health and reducing the medical problems they face as adults. The acute complications for infants born prematurely often require intensive care management and are followed by long-lasting cognitive, sensory, motor, and cardiovascular deficits that substantially limit adult capabilities and survival. The inability to effectively reduce preterm birth stems from the failure to understand normal mechanisms of parturition in humans.

Clock gene expression in gravid uterus and extra-embryonic tissues during late gestation in the mouse.

Evidence in humans and rodents suggests the importance of circadian rhythmicity in parturition. A molecular clock underlies the generation of circadian rhythmicity. While this molecular clock has been identified in numerous tissues, the expression and regulation of clock genes in tissues relevant to parturition is largely undefined.

TAK1 targeting by glucocorticoids determines JNK and IkappaB regulation in Toll-like receptor-stimulated macrophages.

Glucocorticoids potently attenuate the production of inflammatory mediators by macrophages, a primary effector of innate immunity. Activation of different macrophage Toll-like receptors (TLRs) by their respective ligands presents a powerful system by which to evaluate stimulus-dependent glucocorticoid effects in the same cell type. Here, we test the hypothesis that glucocorticoids, acting through the glucocorticoid receptor, modulate macrophage activation preferentially depending upon the TLR-selective ligand and TLR adapters.

Impaired steroidogenesis and implantation failure in Bmal1-/- mice.

Evidence in humans and rodents suggests that normal circadian rhythmicity is important for supporting reproductive function. A molecular clock underlies circadian rhythmicity. Impaired fertility is observed in some genetically altered mice with deficiencies in genes of the molecular clock, suggesting a critical role for these genes in reproduction.
