Using cDNA database mining strategies and real-time quantitative reverse transcription-PCR, we identified B7-H4 as a novel gene that is overexpressed in ovarian and breast cancer tissues when compared with normal tissues. The gene encodes a protein of 282 amino acids with a signal sequence, an immunoglobulin domain, and a COOH-terminal hydrophobic transmembrane domain. Immunohistochemistry expe...
Depsipeptide is in clinical trials for chronic lymphocytic leukemia (CLL) on the basis of earlier observations demonstrating selective in vitro activity in CLL. We sought to determine the relationship of histone H3 and H4 acetylation, inhibition of histone deacetylase, and apoptosis observed in CLL cells to justify a pharmacodynamic end point in these clinical trials. We demonstrate that in vit...
PURPOSE The diagnosis of clinically early-stage (T1) renal cell carcinoma (RCC) has increased. The present study evaluated the association of B7-H4 expression on the pathological outcome and recurrence of carcinoma in the T1 stage of RCC. MATERIALS AND METHODS Among patients who underwent partial or radical nephrectomy after diagnosis of T1 stage RCC during the period of January 2000 to March...
Autoreactive T cells responding to systemic autoantigens have been characterized in patients and mice with autoimmune diseases and in healthy individuals. Using peptides covering the whole sequence of histone H4, we characterized several epitopes recognized by lymph node Th cells from nonsystemic lupus erythematosus-prone mice immunized with the same peptides, the H4 protein, or nucleosomes. Mu...
واکنش های چند جزیی ایزوسیانید ها، جایگاه مهمی در سنتز مواد شیمی آلی، به ویژه سیستم های هتروسیکل گوناگون دارند . در این پایان نامه، ما واکنش 3,1- دی ایمینو ایزوایندولین با دی آلکیل استیلن دی کربوکسیلات ها را در مجاورت آلکیل ایزوسیانید ها گزارش می کنیم که منجر به تشکیل ترکیبات هتروسیکلی از مشتقات پیریمیدین می شود. در این واکنش ها 3,1-دی ایمینو ایزو ایندولین به عنوان یک nh- اسید و منبع پروتون اسید...
efficient use of natural and biological cycles such as nitrogen fixation by legumes may stimulate yield of non-legumes crops in an intercropped system. in order to evaluate spring barley (h) and annual alfalfa (m) intercropping, a study was conducted in the research field of university of tehran (located in karaj) during 2009-2010 growing season. in this research, a randomized complete block de...
BACKGROUND Novel vaccine strategies are required to provide protective immunity in tuberculosis (TB) and prevent development of active disease. We investigated the safety and immunogenicity of a novel TB vaccine candidate, H4:IC31 (AERAS-404) that is composed of a fusion protein of M. tuberculosis antigens Ag85B and TB10.4 combined with an IC31® adjuvant. METHODS BCG-vaccinated healthy subjec...
An in vitro transcription system has been developed from 0.3M NaCl extracts of nuclei of Drosophila embryos. Optimal transcription in the Drosophila embryo extract (DEX) was at 5mM MgCl2, 70mM KCl, 25 degrees C and with promoter concentrations of 0,75-1.0 pmol/assay. In vitro transcription from the Adenovirus-2 major late and the Drosophila histone gene promoters was studied in particular. S1-n...
Dosage compensation balances gene expression levels between the sex chromosomes and autosomes and sex-chromosome-linked gene expression levels between the sexes. Different dosage compensation strategies evolved in different lineages, but all involve changes in chromatin. This paper discusses our current understanding of how modifications of the histone H4 tail, particularly changes in levels of...
