Lymphangioleiomyomatosis (LAM) is an often fatal disease primarily affecting young women in which tuberin (TSC2)-null cells metastasize to the lungs. The mechanisms underlying the striking female predominance of LAM are unknown. We report here that 17-beta-estradiol (E(2)) causes a 3- to 5-fold increase in pulmonary metastases in male and female mice,(More)
PURPOSE To test the effects of antisense (AS)-MDM2 alone and with androgen deprivation (AD), radiotherapy (RT), and AD + RT on wild-type LNCaP cells in an orthotopic in vivo model. METHODS Androgen-sensitive LNCaP cells were grown in the prostates of nude mice. Magnetic resonance imaging-based tumor volume and serum prostate-specific antigen (PSA)(More)
PURPOSE mTOR (mammalian target of rapamycin) plays a central role in regulating cell growth and cell cycle progression and is regarded as a promising therapeutic target. We examined whether mTOR inhibition by RAD001 (everolimus) is therapeutically efficacious in the treatment of ovarian cancer as a single agent and in combination with cisplatin. (More)
The mammalian target of rapamycin (mTOR) is thought to play a critical role in regulating cell growth, cell cycle progression, and tumorigenesis. Because the AKT-mTOR pathway is frequently hyperactivated in ovarian cancer, we hypothesized that the mTOR inhibitor RAD001 (Everolimus) would inhibit ovarian tumorigenesis in transgenic mice that spontaneously(More)
Epithelial ovarian cancer (EOC) is the most commonly fatal gynecologic malignancy in developed countries. Most EOC patients are diagnosed at an advanced stage when disease has spread beyond the ovary. While many patients initially respond to surgery and chemotherapy, the long-term prognosis is generally unfavorable, with recurrence and development of(More)
A significant proportion of colorectal adenomas, in particular those that lack an elevated growth component, continue to escape detection during endoscopic surveillance. Elevation of the activity of matrix metalloproteinases (MMPs), a large family of zinc endopeptidases, in adenomas serves as a biomarker of early tumorigenesis. The goal of this study was to(More)
PURPOSE ATN-161 (Ac-PHSCN-NH(2)) is an integrin-binding peptide that is currently in phase II trials in cancer patients. This peptide has been shown to have antitumor activity in a number of different preclinical models. EXPERIMENTAL DESIGN In this study, we examined the binding, biodistribution, and dose and biomarker response of ATN-161 in several(More)
This article presents a microscopic MR technique for imaging small mammalian fetuses in utero and in vivo which can be used as a tool for studying normal and abnormal development in small animal fetal models, for targeting in utero intervention in such models, and for following development serially. This new method is applied to a rat model of congenital(More)
Although much is known about lymphocytic choriomeningitis virus (LCMV) infection and the subsequent immune response in its natural murine host, some crucial aspects of LCMV-mediated pathogenesis remain undefined, including the underlying basis of the characteristic central nervous system disease that occurs following intracerebral (i.c.) challenge. We show(More)
Autosomal dominant polycystic kidney disease (ADPKD) is a progressive genetic syndrome with an incidence of 1:500 in the population, arising from inherited mutations in the genes for polycystic kidney disease 1 (PKD1) or polycystic kidney disease 2 (PKD2). Typical onset is in middle age, with gradual replacement of renal tissue with thousands of(More)
