The heterogeneous nuclear RNP (hnRNP) A1 protein is one of the major pre-mRNA/mRNA binding proteins in eukaryotic cells and one of the most abundant proteins in the nucleus. It is localized to the nucleoplasm and it also shuttles between the nucleus and the cytoplasm. The amino acid sequence of A1 contains two RNP motif RNA-binding domains (RBDs) at the amino terminus and a glycine-rich domain ...
Infections with extraintestinal avian pathogenic Escherichia coli (APEC) cause significant economic losses in the poultry industry worldwide. In a previous study we applied signature-tagged transposon mutagenesis and identified 28 virulence-associated genes in APEC strain IMT5155 (O2 : H5 : K1). One of them, yjjQ, encodes a putative transcriptional regulator whose function and role in pathogene...
CD147 is a widely expressed transmembrane protein that mediates signal transduction, and it plays important roles in many physiological and pathological processes, such as tumor invasion and metastasis. The extracellular portion of CD147 (CD147(EC)) is responsible for its functional interactions with different signaling molecules. Due to the existence of two disulfide bonds, CD147(EC) is mainly...
Eradication of human immunodeficiency virus type 1 (HIV-1) by vaccination with epitopes that produce broadly neutralizing antibodies is the ultimate goal for HIV prevention. However, generating appropriate immune responses has proven difficult. Expression of broadly neutralizing antibodies by vaginal colonizing lactobacilli provides an approach to passively target these antibodies to the mucosa...
Chromosome loss from par mutants of Pseudomonas putida depends on growth medium and phase of growth.
The proteins encoded by chromosomal homologues of the parA and parB genes of many bacterial plasmids have been implicated in chromosome partitioning. Unlike their plasmid counterparts, mutant phenotypes produced by deleting these genes have so far been elusive or weakly expressed, except during sporulation. Here the properties of Pseudomonas putida strains with mutations in parA and parB are de...
Clavibacter michiganensis, subsp. michiganensis is a Gram-positive plant pathogen infecting tomato (Solanum lycopersicum). Despite a considerable economic importance due to significant losses of infected plants and fruits, knowledge about virulence factors of C. michiganensis subsp. michiganensis and host-pathogen interactions on a molecular level are rather limited. In the study presented here...
توانایی رشد سریع اکالیپتوس ها سبب شده تا این جنس در جنگل کاری، مصارف صنعتی و دارویی اهمیت فوق العاده ای پیدا کند. گونه درختی e. maculata hookاز نظر تولید برخی ترکیبات شیمیایی و مصارف دارویی نسبت به سایر اکالیپتوس ها از اهمیت خاصی برخوردار است. از طرفی به دلیل مشکلات تکثیر جنسی و غیرجنسی این گونه، در این تحقیق امکان تکثیر این گیاه به روش کشت درون شیشه ای با استفاده از ریزنمونه های پایه بالغ مور...
اثرات پیش تیمار سرمایی و گرمایی روی غنچه ها و بساکهای کشت شده در4 لاین گوجه فرنگی و 6 هیبرید حاصل از آنها در سه محیط کشت، مورد بررسی قرار گرفت. پیش تیمارهای دمایی شامل پیش تیمار سرمایی (?c4 بمدت 48 ساعت و ?c10 بمدت 10 روز)، پیش تیمار گرمایی (?c35 بمدت 4 روز) و ترکیب پیش تیمار سرمایی و گرمایی (?c4 بمدت 48 ساعت سپس ?c35 بمدت 4 روز و تیمار دیگر ?c35 بمدت 4 روز سپس ?c4 بمدت 48 ساعت) بودند. کشتهای ...

P strains of Drosophila are distinguished from M strains by having P elements in their genomes and also by having the P cytotype, a maternally inherited condition that strongly represses P-element-induced hybrid dysgenesis. The P cytotype is associated with P elements inserted near the left telomere of the X chromosome. Repression by the telomeric P elements TP5 and TP6 is significantly enhance...
