Trophoblast invasion of the uterine extracellular matrix, a critical process of human implantation and essential for fetal development, is a striking example of controlled invasiveness. To identify molecules that regulate trophoblast invasion, mRNA signatures of trophoblast cells isolated from first trimester (high invasiveness) and term placentae (no/low(More)
OBJECTIVE To compare the effects of a 4-month strength training (ST) versus aerobic endurance training (ET) program on metabolic control, muscle strength, and cardiovascular endurance in subjects with type 2 diabetes mellitus (T2D). DESIGN Randomized controlled trial. SETTING Large public tertiary hospital. PARTICIPANTS Twenty-two T2D participants (11(More)
Over 1 billion people are estimated to be overweight, placing them at risk for diabetes, cardiovascular disease, and cancer. We performed a systems-level genetic dissection of adiposity regulation using genome-wide RNAi screening in adult Drosophila. As a follow-up, the resulting approximately 500 candidate obesity genes were functionally classified using(More)
Immune cells are somewhat unique in that activation responses can alter quantitative phenotypes upwards of 100,000-fold. To date little is known about the metabolic adaptations necessary to mount such dramatic phenotypic shifts. Screening for novel regulators of macrophage activation, we found nonprotein kinases of glucose metabolism among the most enriched(More)
Heme oxygenase (HO) seems to be a novel protective factor with potent anti-inflammatory, anti-oxidant, and anti-proliferative effects. HO-1, the inducible isoform, is expressed in various tissues and is upregulated by multiple stimuli. However, humans differ quantitatively in their ability to mount an HO-1 response, modulated by two potentially functional(More)
Carbon monoxide (CO) suppresses proinflammatory responses in macrophages reacting to LPS. We hypothesize that CO acts by inducing a molecule(s) that suppresses the inflammatory response to subsequent stress. Exposure of macrophages to CO alone in vitro produced a brief burst of mitochondrial-derived ROS, which led to expression of PPARgamma. PPARgamma(More)
OBJECTIVE Women with prior gestational diabetes mellitus (pGDM) are at increased risk of developing type 2 diabetes and associated vasculopathy. Because increased fat mass and inflammatory processes are angiopathic risk factors, the relationship between insulin sensitivity, parameters of subclinical inflammation, and plasma concentrations of adipocytokines(More)
BACKGROUND Increased gamma glutamyltransferase (GGT) is associated with cardiovascular disease. To date, however, few studies with sufficient sample size and follow-up have investigated the association of GGT with all-cause mortality. METHODS The relation of GGT to the risk of death was examined in a cohort of 283 438 first attendants (inpatients or(More)
BACKGROUND Chronic and acute infections are associated with an increased risk of stroke. The inflammatory response can be influenced by functional polymorphisms in components of the immune system. We hypothesized that these polymorphisms may also modulate the risk of ischemic cerebrovascular events. METHODS We determined the frequency of polymorphisms in(More)
BACKGROUND Epidemiological studies indicate that genetic factors play a role in the risk of stroke, particularly in younger individuals, but the role of single-nucleotide polymorphisms (SNPs) is controversial. We tested the possible association of a number of previously described SNPs with stroke risk. METHODS We investigated the prevalence of 60(More)
