DNA REPLICATION AND SYNTHESIS OF DNABINDING PROTEINS IN THE CHLOROPLASTS OF A CALLUS CULTURE
Continuous labelling of callus with H-thymidine results in intermittent peaks of H-DNA per chloroplast, showing synchrony of division. The increase in H-DNA could be due to several replication rounds, and the drop to successive plastid divisions without intervening DNA synthesis. The level of DNA-binding proteins in the chloroplast parallels the peaks of plastidal DNA synthesis; such pro...
متن کاملDesigning and Development of a DNA Vaccine Based On Structural Proteins of Hepatitis C Virus
Background: Hepatitis C virus (HCV) infection is one of the most prevalent infectious diseases responsible for high morbidity and mortality worldwide. Therefore, designing new and effective therapeutics is of great importance. The aim of the current study was to construct a DNA vaccine containing structural proteins of HCV and evaluation of its expression in a eukaryot...
متن کاملAPPLICATION OF TWO-DIMENSIONAL ELECTROPHORESIS AND NIH 3T3 CELL TRANSFECTION ASSAY IN THE STUDY OF TUMOR-AS SOCIATED PROTEINS AND GENOMIC DNA TUMOROGENICITY IN MALIGNANT HUMAN ESOPHAGEAL SPECIMENS
Total protein and DNA extracted from histologically diagnosed normal nonmalignant and esophageal tumor tissues were used for analysis of polypeptides pattern by two-dimensional gel electrophoresis and DNA transforming activity in NIH 3T3 cell transfection assay, respectively. In comparison to normal tissues, eight polypeptides underwent down-regulation or disappeared, while seven polypeptid...
متن کاملجداسازی پروتئین LMG از بافت کبد موش و میانکنش آن با
ABSTRACT In eukaryote cells, DNA is complexed with a series of basic proteins making units of chromatin structure named nucleosomes. In addition, nonhistone proteins with different function are the components of chromatin. Among these proteins, a group with a low mobility on gel electrophoresis have been identified and named LMG. In this study a LMG protein with a molecular weigh of 160 ...
متن کاملArabidopsis leaf plasma membrane proteome using a gel free method: Focus on receptor–like kinases
The hydrophobic proteins of plant plasma membrane still remain largely unknown. For example in the Arabidopsis genome, receptor-like kinases (RLKs) are plasma membrane proteins, functioning as the primary receptors in the signaling of stress conditions, hormones and the presence of pathogens form a diverse family of over 610 genes. A limited number of these proteins have appeard in pr...
