Cellular Morphology and Immunologic Properties of Escherichia coli Treated With Antimicrobial Antisense Peptide Nucleic Acid
Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in th...
متن کاملInhibition of a DNA-helicase by peptide nucleic acids.
Bis-peptide nucleic acid (bis-PNA) binding results in D-loop formation by strand displacement at complementary homopurine stretches in DNA duplexes. Transcription and replication in intact cells is mediated by multienzymatic complexes involving several proteins other than polymerases. The behaviour of the highly stable clamp structure formed by bis-PNAs has thus far been studied with respect to...
متن کاملElectroporation-based delivery of cell-penetrating peptide conjugates of peptide nucleic acids for antisense inhibition of intracellular bacteria.
Cell penetrating peptides (CPPs) have been used for a myriad of cellular delivery applications and were recently explored for delivery of antisense agents such as peptide nucleic acids (PNAs) for bacterial inhibition. Although these molecular systems (i.e. CPP-PNAs) have shown ability to inhibit growth of bacterial cultures in vitro, they show limited effectiveness in killing encapsulated intra...
متن کاملfunctional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner
نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
Antisense properties of peptide nucleic acids.
PNA is a nucleic acid analog with an achiral polyamide backbone consisting of N-(2-aminoethyl)glycine units (figure 1). The purine or pyrimidine bases are linked to the each unit via a methylene carbonyl linker (1-3) to target the complementary nucleic acid (4). PNA binds to complementary RNA or DNA in a parallel or antiparallel orientation following the Watson-Crick base-pairing rules (5-7). T...
