Project description:EXPERIMENT: The animal experiments were performed at Shin Nippon Biomedical Laboratories (SNBL), Ltd. (Kagoshima, Japan) in compliance with the Guideline for Animal Experimentation (1987), and in accordance with the Law Concerning the Protection and Control of Animals (1973) and the Standards Relating to the Care and Management of Experimental Animals (1980). This study was approved by the Institutional Animal Care and Use Committee of SNBL and performed in accordance with the ethics criteria contained in the bylaws of the SNBL committee. Each female monkey was paired with a male of proven fertility for one day between day 11 and day 15 of the menstrual cycle. Pregnant females, aged 5-8 years and weighing 2.84-3.76 kg on day 22 of gestation, were allocated randomly to two groups, each with three monkeys, and housed individually. The monkeys were orally dosed with (±)-thalidomide (Lot no. SDH7273/SDJ3347, Wako Pure Chemical Industries, Ltd., Osaka, Japan) at 0 or 20 mg/kg by oral intubation on day 26 of gestation, which was during the critical period for thalidomide-induced teratogenesis [Delahunt and Lassen, 1964; Hendrickx, 1973]. Dosage was adjusted to the body weight on day 22 of gestation and the drug was packed in a gelatin capsule. Control monkeys received the capsule only. ANIMAL MODEL: Macaca fascicularis INTERVAL: NON.

Project description:We used the rhesus monkey (Macaca mulatta) as our animal model for the current study with two goals: to characterize the changes in histology and gene expression from early to late gestation (prenatal uterine organogenesis) and to determine if there are effects of prenatal exposure to bisphenol A (BPA) on the developing female uterus. Pregnant rhesus monkeys carrying a female fetus (N=22) were divided into two experimental groups, based on gestational timing: 'early' (N=10) and 'late' (N=12). These groups were then equally sub-divided into control (unexposed) and BPA (exposed) groups (5 Early Control, 5 Early BPA-exposed, 6 Late Control and 6 Late BPA-exposed.) The BPA-exposed monkeys received a deuterated BPA (dBPA, CDN Isotopes, Quebec, Canada) fruit treat on a daily basis, at a dose of 400ug/kg/day). The dosing was aimed at achieving serum levels of BPA detected in adult human biomonitoring studies. The control animals received a vehicle control on a daily basis. The 'early' time period (mid-gestation) referred to gestational days 50-100, approximating the second trimester of human gestation. The fetal monkeys in the 'early' group were delivered via cesarean section on gestation day 100 and euthanized. Samples of maternal and fetal blood and amniotic fluid were obtained. Maternal and fetal weights were also recorded. The 'late' time period referred to gestational days 100-165, approximating the third trimester of human gestation. The fetal monkeys in the 'late' group were delivered vaginally and euthanized. There were five idiopathic stillbirths (2 Control, 3 BPA-exposed) in the late group. Samples of maternal and fetal blood and amniotic fluid were obtained. Maternal and fetal weights were also recorded. After delivery, the fetal uterus was excised and cut sagitally from fundus to cervix; one side was fixed for histological evaluation and the other half was frozen for analysis of gene expression by microarray. The stillbirths were excluded from the microarray.

Project description:For the chronic inflammation-related colon cancer model (AOM/DSS-colon cancer model), 3-month-old Dnase1l3 WT and KO mice were injected with AOM (8 mg/kg, body weight). One week later, mice were challenged with 2.5% DSS water for 7 days followed by a 14-day recovery with regular drinking water for three cycles. Body weight, rectal bleeding and diarrhea were monitored during the entire experiment. Mice with more than 25% weight loss were removed during the experiment. For the AOM model, 2-month-old Dnase1l3 WT and KO mice were injected intraperitoneally with AOM (8 mg/kg, body weight). Colon tissues were isolated 9 hours, or five days after injection. All animal experiments were conducted in accordance with guidelines of NIEHS/NIH Animal Care and Use Committee.

Project description:Zika virus (ZIKV) is responsible for a major current outbreak in the Americas and has been causally associated with fetal microcephaly as well as Guillain-Barre syndrome in adults. However, the immune responses associated with controlling ZIKV replication remain poorly characterized. Here we report a detailed analysis of innate and adaptive immune responses following ZIKV infection in 16 rhesus monkeys. A robust proinflammatory innate immune response was observed within the first few days of infection, including upregulation of type 1 interferon, which correlated directly with viral loads. Immunomodulatory pathways, including IL-10 and TGF-β, were also upregulated. ZIKV-specific neutralizing antibodies emerged rapidly by day 7 and correlated inversely with viral loads, which were undetectable in peripheral blood by day 6-10. In contrast, virus replication persisted in cerebrospinal fluid (CSF) for at least 21-42 days in 75% (3 of 4) of the monkeys that received the lowest dose of ZIKV tested, and ZIKV-specific antibodies were essentially undetectable in CSF. These data suggest that antibodies play a critical role in the rapid control of acute viremia in the periphery but were largely excluded from the central nervous system, allowing viral persistence at this immuonoprivileged site. 16 outbred, Indian-origin, adult male and female rhesus monkeys (Macaca mulatta) were included in this study. All monkeys were housed at Bioqual, Rockville, MD. Animals were infected with 103-106 pfu (106-109 vp) of our ZIKV-BR or ZIKV-PR challenge stocks by the s.q. route (N=2/group). All animal studies were approved by the appropriate Institutional Animal Care and Use Committee (IACUC).

Project description:Smoking cessation is the most effective measure for reducing the risk of smoking-related diseases but switching to less harmful products (modified-risk tobacco products) can be an alternative for smokers who would otherwise not quit. In an 18-month chronic carcinogenicity/toxicity study in A/J mice (OECD Test Guideline 453), we assessed aerosol from the Tobacco Heating System 2.2 (THS 2.2), a candidate modified-risk tobacco product based on the heat-not-burn principle, compared with 3R4F cigarette smoke (CS). To capture toxicity- and disease-relevant mechanisms, we complemented standard toxicology endpoints with in-depth systems toxicology analyses. Briefly, female A/J mice were exposed to fresh air (Sham), three concentrations of THS 2.2 aerosol corresponding to nicotine concentrations of 6.7 (Low; L), 13.4 (Medium; M), and 26.8 (High; H) µg nicotine\L test atmosphere, or to one concentration of 3R4F CS (13.4 µg nicotine\L test atmosphere) in whole-body exposure chambers for 6 h per day, 5 days per week, and up to 18 months. Interim dissections were scheduled for months 1, 5, and 10. Male mice were exposed to either fresh air (Sham) or to the high THS 2.2 aerosol concentration for 15 months. Chronic toxicity and carcinogenicity endpoints outlined in the OECD protocol were assessed; detailed findings will be reported separately (Wong et al.). For evaluation of non-OECD endpoints following a systems toxicology approach (proteomics, transcriptomics, and genomics), several tissues were collected for further analysis. Housing and all procedures involving animals were performed in accordance with the approved Institutional Animal Care and Use Committee protocol in an Agri-Food & Veterinary Authority of Singapore-licensed and Association for Assessment and Accreditation of Laboratory Animal Care International-accredited facility, where the care and use of the animals for scientific purposes were in accordance with the National Advisory Committee for Laboratory Animal Research (NACLAR) Guideline (NACLAR, 2004). Animals allocated to the omics endpoints (N=8-20) were dissected within 16-24 h of the last exposure and following randomization of all planned necropsies for the dissection time point in question. All efforts to minimize potential nucleic acid and protein degradation were made, and samples were frozen as rapidly as possible once ex vivo. Lungs collected after month 1 were snap-frozen and the right caudal lobe was used for proteomics analysis. These are the protein expression data for the respiratory nasal epithelium assessed by iTRAQ®-based quantitative proteomics.

Project description:Thalidomide Exerts Distinct Molecular Antileukemic Effects and Combined Thalidomide/Fludarabine Therapy is Clinically Effective in High-Risk Chronic Lymphocytic Leukemia Background: Thalidomide represents a promising immunomodulatory drug that targets both leukemia cells and the tumor microenvironment. Methods: We treated chronic lymphocytic leukemia (CLL) patients with a combined thalidomide/fludarabine regimen and monitored cellular and molecular changes induced by thalidomide in-vivo prior to fludarabine treatment. Thalidomide was given daily (100mg p.o./day) and fludarabine was administered on days 7-11 (25 mg/m² i.v./day) within each 4-week cycle (maximum of 6 cycles). Twenty patients received thalidomide/fludarabine as first line therapy and 20 patients were previously treated. Unmutated IgVH mutation status was found in 36 cases and 13 had high-risk cytogenetic aberrations (deletion of 17p13 or 11q22-q23). Results: The overall response rate was 80% and 25% for untreated and previously treated patients, respectively. While thalidomide effectively reduced the number of CLL cells, the number of CD3 lymphocytes showed no significant change, but the number of CD4+CD25hiFOXP3+ T-regulatory cells was significantly decreased. Gene expression profiling revealed a thalidomide induced signature containing both targets known to play a role in immunomodulatory drug action as well as novel candidate genes. Conclusions: Combined thalidomide/fludarabine therapy demonstrated efficacy in high-risk CLL patients. Furthermore, our study provides novel biological insights into thalidomide effect, which might act by enhancing apoptosis of CLL cells and reducing Tregs, thereby enabling T-cell dependent anti-tumor effect.

Project description:Obesity is associated with a chronic, low-grade, systemic inflammation that may contribute to the development of insulin resistance and type 2 diabetes. Resveratrol, a natural compound with anti-inflammatory properties, is shown to improve glucose tolerance and insulin sensitivity in obese mice and humans. Here we tested the effect of a 2-year resveratrol administration on the pro-inflammatory profile and insulin resistance caused by a high-fat, high-sugar (HFS) diet in white adipose tissue (WAT) from rhesus monkeys. Eighty mg/day of resveratrol for 12-month followed by 480 mg/day for the second year decreased adipocyte size, increased sirtuin 1 expression, decreased NF-kB activation and improved insulin sensitivity in visceral but not subcutaneous WAT from HFS-fed animals. These effects were reproduced in 3T3-L1 adipocytes cultured in media supplemented with serum from monkeys fed HFS +/- resveratrol diets. In conclusion, chronic administration of resveratrol exerts beneficial metabolic and inflammatory adaptations in visceral WAT from diet-induced obese monkeys. Twenty-four adult (7-13 years old) male rhesus monkeys (Macaca mulatta) were housed individually in standard nonhuman primate caging on a 12h light/12h dark cycle, room temperature (78 +/- 2 degrees F), and humidity at 60 +/- 20%. One pairing was maintained throughout the study; all other monkeys had extensive visual, auditory, and olfactory but limited tactile contact with monkeys housed in the same room. Monkeys received 2 meals per day at estimated ad libitum levels throughout the study. Water was always available ad libitum. Monkeys were monitored minimally 3 times daily by trained animal care staff. During baseline assessments, all monkeys were maintained on a commercially available closed formula monkey chow. After baseline assessment, four male rhesus monkeys remained on the healthy standard diet (SD), 10 male rhesus monkeys were begun on a high fat/high sucrose (HFS) diet and 10 male rhesus monkeys were begun on a high fat/high sucrose (HFS) diet plus Resveratrol, 80mg/day. After one year of dietary intervention, the amount of resveratrol was increased to 480mg/day for one additional year. Tissues were then harvested for the array experiments.

Project description:We have previously showed that whey protein hydrolysate (WPH) causes a greater increase in muscle protein synthesis than an identical composition of amino acids mixture does. The present study was conducted to investigate a comparative effect of WPH on gene expression. Male Sprague-Dawley rats subjected to a 2-h swimming exercise were administered either a carbohydrate-amino acid diet or a carbohydrate-WPH diet immediately after exercise. One hour after exercise, epitrochlearis muscle mRNA was sampled and subjected to DNA microarray analysis. As a result, ingestion of WPH altered 189 genes in considering the false discovery rate. Among the upregulated genes, 8 Gene Ontology (GO) terms were enriched, which included key elements in muscle repair after exercise such as Cd24, Ccl2, Ccl7 and Cxcl1. On the other hand, 9 GO terms were enriched in the gene sets downregulated by ingestion of WPH and these GO terms fell into 2 clusters, 'regulation of ATPase activity' and 'immune response'. Furthermore, we found that WPH activate the 2 upstream proteins, extracellular signal-regulated kinase 1/2 (ERK1/2) and hypoxia-inducible factor-1a (HIF-1a), which may act as key factors for regulation of gene expression. These results suggest that ingestion of WPH, compared to an identical composition of amino acid mixture, induces greater changes in the after-exercise gene expression profile via activation of the proteins, ERK1/2 and HIF-1a. Male Sprague-Dawley rats (5-week-old) with body weights of approximately 150 g each (CLEA Japan, Inc., Tokyo, Japan) were used in this study. Rats were maintained at 23 +/- 2C, with lights on from 8:00 to 20:00 and off from 20:00 to 8:00. Rats had free access to food (protein 23.6%, fat 5.3%, carbohydrate 54.4%, ash 6.1%, fiber 2.9%, moisture 7.7%, MF, Oriental Yeast Co., Ltd., Osaka, Japan) and water. After 2- or 3-day acclimation, the rats were pre-trained to swimming exercise for 3 days. One day before the experiment, they were fed 5 g of a restricted diet (MF, Oriental Yeast Co., Ltd., Osaka, Japan). On the day of the experiment, rats swam for 2 hours, with 4 rats swimming simultaneously in a barrel filled with water to a depth of 50 cm, allowing an average surface area of 400 cm2 for each animal. The water temperature was maintained at a constant of 35C. Immediately following exercise, rats were given one of two isoenergetic test solutions by gavage. These solutions contained 44 kJ in a four-test dose that represented about 15% of daily energy needs and included either a mixed meal containing carbohydrate and amino acid mixture (AAM) or a mixed meal containing carbohydrate and whey protein hydrolysate (WPH; Meiji Co., Ltd., Japan). This study was approved by the Animal Committee of Food Science Research Lab., Meiji Co., Ltd., with the animals receiving care according to the guidelines laid down by this committee.
