Transglutaminases are Ca2+-dependent intra-and extracellular enzymes catalyzing the cross-linking between proteins and/or polyamines, thereby eliciting divergent physiological effects such as fibrin clot stabilization or hair follicle cross-linking. A secretory transglutaminase (EC was isolated from the coagulating gland of the rat. The protein is(More)
Noncoding polymorphisms in the fat mass and obesity-associated (FTO) gene represent common alleles that are strongly associated with effects on food intake and adiposity in humans. Previous studies have suggested that the obesity-risk allele rs8050136 in the first intron of FTO alters a regulatory element recognized by the transcription factor CUX1, thereby(More)
Perturbations in the functional integrity of the leptin axis are obvious candidates for mediation of altered adiposity. In a large number of genetic association studies in humans, the nonconservative LEPR Q223R allele has been inconsistently associated with adiposity. Subtle, long-term effects of such genetic variants can be obscured by effects of the(More)
Retinoic acid signaling is required for maintaining a range of cellular processes, including cell differentiation, proliferation, and apoptosis. We investigated the actions of all-trans-retinoic acid (atRA) signaling in pancreatic β-cells of adult mice. atRA signaling was ablated in β-cells by overexpressing a dominant-negative retinoic acid receptor(More)
Prader-Willi syndrome (PWS) is caused by a loss of paternally expressed genes in an imprinted region of chromosome 15q. Among the canonical PWS phenotypes are hyperphagic obesity, central hypogonadism, and low growth hormone (GH). Rare microdeletions in PWS patients define a 91-kb minimum critical deletion region encompassing 3 genes, including the(More)

The purpose of this article is to provide a review of the small but loud debate that has surrounded fluoride over the past 50 years. The benefits of fluoridation and its effect on public health are well known throughout the dental community. What is far less well known are the objections from people— in the tradition of the old amalgam and radiograph(More)
BACKGROUND The adipokine hormone, leptin, is a major component of body weight homeostasis. Numerous studies have been performed administering recombinant mouse leptin as an experimental reagent; however, the half-life of circulating leptin following exogenous administration of recombinant mouse leptin has not been carefully evaluated. METHODS Exogenous(More)
