Liposome-based GeneFECTOR (Venn Nova, FL, USA) was used for transfecting cells with the DNA expression constructs.
Two polyethylene oxide-based delivery systems comprised of reacting PEG polymers were designed for the delivery of DNA expression vectors.
The messenger RNAs from these tissues were used on complementary DNA expression arrays; 488 genes were analyzed.
We have developed a novel DNA expression system, based on the Semliki Forest virus (SFV) replicon, which combines a wide choice of animal cell hosts, high efficiency and ease of use.
NCOR1 is a transcriptional coregulatory protein that appears to assist nuclear receptors in the downregulation of DNA expression through recruitment of histone deacetylases to DNA promoter regions; it is a principal regulator in neural stem cells51.
The researchers pooled information from each person's transcriptome, a collection of molecules that reveal patterns of DNA expression; proteome, the complete set of proteins an individual actively produces; microbiome; and genome.
Traditionally, such linear DNA expression templates (LET) have been vulnerable to degradation by nucleases present in the cell lysate, leading to lower yields.
Co-transfection of SFV DNA expression and helper vectors generated titers of 106 particles/ml, which is approximately 100 1000 lower than using RNA-based SFV vectors.
A number of adjuvants have been designed to improve plasmid DNA immunogenicity, either by directly stimulating the immune system or by enhancing plasmid DNA expression.
By cell type-specific inactivation of mitochondrial transcription factor A, a protein essential for mitochondrial DNA expression and maintenance, dopamine neurons were rendered respiratory chain deficient.
The success of DNA expression microarrays has been followed by applications of this technology to molecular diagnosis, mainly in the fields of biology and medicine.
