The epicardium plays an essential role in coronary artery formation and myocardial development, but signals controlling the development and differentiation of this tissue are not well understood. To investigate the role of platelet-derived growth factor receptor (PDGFR)beta in development of epicardial-derived vascular smooth muscle cells (VSMCs), we(More)
The head bobber transgenic mouse line, produced by pronuclear integration, exhibits repetitive head tilting, circling behavior, and severe hearing loss. Transmitted as an autosomal recessive trait, the homozygote has vestibular and cochlea inner ear defects. The space between the semicircular canals is enclosed within the otic capsule creating a vacuous(More)
In this paper, I analyze the influence of labor market conditions on wages by considering an insurance model of the employment relationship. The model allows for limited commitment on both sides of the labor contract, and has three main implications: First, wages can be correlated with both the best and the worst labor market conditions since the start of a(More)
Background: Tumor thickness is of great importance in the management of cutaneous malignant melanoma (MM): this variable not only affects prognosis but is also a key factor in planning surgical margins and selecting candidates for sentinel node biopsy. Breslow depth is the standard histologic measure of thickness, but technological advances have provided(More)
REV-ERBα and REV-ERBβ are heme regulated nuclear receptors that are known to regulate metabolic pathways. We previously demonstrated that treatment of mice with synthetic REV-ERB agonists suppressed plasma cholesterol levels and the hepatic levels of the rate limiting enzyme in cholesterol biosynthesis (3-hydroxy-3-methylglutaryl-CoA reductase). Here, we(More)

BACKGROUND Both nuclear receptor subfamily 2 group F member 1 (NR2F1) and microRNAs (miRNAs) have been shown to play critical roles in the developing and functional inner ear. Based on previous studies suggesting interplay between NR2F1 and miRNAs, we investigated the coregulation between NR2F1 and miRNAs to better understand the regulatory mechanisms of(More)
Mucins are being implicated in diagnosis, prognosis, and as therapeutic targets due to their aberrant expression in a variety of carcinomas. Here, we have analyzed the expression of MUC4 and have compared its potential usefulness in early detection and prognosis of ovarian carcinoma alone and in combination with other mucin antigens, MUC1 and MUC16.(More)
