A novel acyl protecting group for cytosine and adenine has been prepared
from 4-( chloromethyl) benzoic acid. Reaction of the acid with morpholine produces
4-( 4-morpholinyl )methyl benzoic acid which is converted to it's acid chloride
with thionyl chloride. This may be used to acylate cytidine and adenosine under
standard...
In recent years, the general public has recognized the dangers of a high fat diet and
are demanding meat with lower fat content. This demand has stimulated research in the
growth and regulation of adipocytes. However, despite much effort, no adipocyte-specific
plasma membrane markers from any species are available as...
Antisense oligonucleotide (AO)-mediated exon-skipping therapeutics shows great promise in correcting frame-disrupting mutations in the DMD gene for Duchenne muscular dystrophy. However, insufficient systemic delivery limits clinical adoption. Previously, we showed that a glucose/fructose mixture augmented AO delivery to muscle in mdx mice. Here, we evaluated if fructose alone could enhance...
Peptide-phosphorodiamidate morpholino oligomers (PPMOs) are synthetic DNA mimics that bind and silence gene targets. Through designing PPMOs that silence essential or resistance genes in pathogens, these antisense oligomers could be utilized as novel antimicrobials. Towards this end, my thesis employed minimum inhibitory concentration assays (MICs) to identify PPMOs capable of...
Early embryo development is dependent on maternally derived RNA and protein synthesized during oogenesis. In the bovine embryo this dependence lasts until the 8-16 cell stage, at which time embryonic transcripts become essential for continued development. One proposed mechanism for this transition from maternal to zygotic control of development (maternal...
Maternally-derived transcripts and proteins support early bovine and ovine embryo development until the 8- to 16-cell stage, at which time embryonic transcripts become essential for continued development. One purported mechanism for the switch from maternal to zygotic control of development (maternal to zygotic genome activation; MZGA) is the appearance of...
We have recently reported that cell-penetrating peptides (CPPs) and novel chimeric peptides containing CPP (referred as
B peptide) and muscle-targeting peptide (referred as MSP) motifs significantly improve the systemic exon-skipping activity
of morpholino phosphorodiamidate oligomers (PMOs) in dystrophin-deficient mdx mice. In the present study, the general
mechanistic significance of the...
