چکیده
Substantial progress has been made in elucidating the biosynthesis of plant phenolics, one major class of which is the flavonoids. Flavonoids are involyed in many plant functions such as UV protection, defense against pathogen attack, legume nodulation, pigmentation and pollen viability (Firmin et al. 1986, Hahlbrock and Scheel 1989, Dixon and Harrison 1990). Due to such important functions, studies on the fiavonoids have been extensively carried out and the genes involved in this pathway such as chalcone synthase (CHS) and chalcone isomerase (CHI) have been isolated (e.g, Hahlbreck 1981, Hahbrock and Scheel 1989). Special attention is given to the regulation of

Expressional Analysis of Stem Cell Marker SALL4 in Mesencephalon during Chicken Embryogenesis
Background SALL gene family represent a group of evolutionary conserved zinc finger transcription factors which are involved in normal development. It includes four members (SALL1 to SALL4). SALL4 has significant roles in the maintenance of pluripotency and self-renewal, efficient proliferation /stabilization and cell fate decision of embryonic stem cells (ESCs). Our aim in this study was to a...
متن کاملCostal Versus Articular Chondrocytes in Alginate Three-Dimensional Cultures
Given the difficulties in accessing articular cartilage as a source of chondrocytes to be used in fabricating cartilage constructs, alternative sources are required. The present study examined chondrocytes from costal cartilage for their suitability in cartilage tissue engineering. Chondrocytes isolated from rat knee and rib hyaline cartilage were separately mixed with alginate and placed in a ...
متن کاملNucleostemin delays cellular senescence and negatively regulates TRF1 protein stability.
Nucleostemin (NS) encodes a nucleolar GTP-binding protein highly enriched in the stem cells and cancer cells. To determine its biological activity in vivo, we generated NS loss- and gain-of-function mouse models. The embryogenesis of homozygous NS-null (NS(-/-)) mice was aborted before the blastula stage. Although the growth and fertility of heterozygous NS-null (NS(+/-)) mice appeared normal, ...
متن کاملNew p53 Gene Mutation in non-Cancerous Mustard Gas Exposed Lung
Objective Mustard gas (MG) is a poisoning chemical, mutagenic and carcinogenic alkylating agent. It is used during World War I and also Iran-Iraq conflict. The p53 tumor suppressor gene is involved in the pathogenesis of malignant disease. The aim of this study is to determine possible mutation in p53 gene of lung sample from mustard gas exposed patients. Material and Methods Twelve lung bio...
متن کاملThe Mutation of the rpoS Gene, the Central Regulator of Stationary Phase, Affects the Cell Division in Flexibacter chinensis
A one kb portion of the rpoS gene from Flexibacter chinensis was isolated by PCR, sequenced and compared to the rpoS gene of a variety of other organisms. The gene was found to be 98% similar to previously sequenced genes. Mutation of the rpoS gene with tri-parental mating produced strain JR101 and the growth rate of the mutant was compared with that of the wild-type. The mutant grew slower, an...
