Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Viral Structure

Viral Structure

Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

Response Surface Methodology

Response Surface Methodology

Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Production Efficiency

Production Efficiency

Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Trophic Efficiency

Trophic Efficiency

Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

Background:

CRISPR/Cas9, TALE, and zinc finger technologies offer immense potential for understanding genomic functions and treating diseases.
A significant bottleneck in applying these powerful gene editing tools is the lack of efficient delivery methods, especially for large or multiple plasmids.
Current viral and non-viral transfection methods are insufficient for demanding applications, limiting the therapeutic use of TALE and CRISPR platforms.

Purpose of the Study:

To synthesize a novel dendronized polymer as a highly efficient and non-toxic gene transfection agent.
To optimize this polymer as a co-transfection reagent for delivering large and multiple plasmids into cell lines.
To address the limitations in delivering CRISPR/dCas9 and TALE systems for therapeutic applications.

Main Methods:

Synthesis of a novel dendronized polymer.
Optimization of the polymer as a co-transfection reagent for large and multiple plasmids.
Evaluation of transfection efficiency in multiple cell lines compared to a standard reagent (Lipofectamine 2000).

Main Results:

The synthesized dendronized polymer demonstrated highly efficient and non-toxic transfection capabilities.
Optimized polymer significantly improved co-transfection efficiency for large plasmids compared to Lipofectamine 2000.
Enhanced delivery of CRISPR/dCas9 and TALE systems was achieved in multiple cell lines.

Conclusions:

The developed dendronized polymer represents a promising solution for overcoming gene delivery challenges in gene editing technologies.
This novel reagent significantly enhances the co-transfection of large and multiple plasmids, broadening the applicability of CRISPR and TALE systems.
The findings pave the way for more effective therapeutic applications of advanced gene editing tools.
