Functional Analysis of TET-Family 5-Methylcytosine Dioxygenases in Non-CpG DNA Demethylation
(2023)
One of the most widely studied epigenetic marks in DNA is 5-methylcytosine (5mC). Research has indicated that in the mammalian genome around 5-6% of all cytosines are methylated (5mC), with a strong preference for the CpG dinucleotide context...
Ritonavir - A Novel Multidrug Resistance Modulator in Cancer Chemotherapy and Ocular Neovascular Diseases
(2014-08-28)
Multidrug resistance (MDR), a clinical outcome characterized by subtherapeutic
intracellular drug concentration, is one of the predominant factors limiting effective cancer
chemotherapy. Several possible mechanisms and ...
Evaluation of therapeutic effect of PCBP2 siRNA on hepatic stellate cells and development of a streptavidin-based siRNA delivery system
(2014)
Type I collagen accumulates during liver fibrosis primarily because α-complex protein-2 (αCP2), encoded by the poly(rC) binding protein 2 (PCBP2) gene, binds to the 3′end of the collagen mRNA and increases its half-life. Study in chapter 3 aimed...
Total synthesis of (±)-cis-trikentrin B, (±)-herbindole A and (±)-herbindole B. investigation into the regioselectivity of 6,7-Indole aryne cycloadditions
(2013)
Total synthesis of benzannulated indole alkaloid natural products (±)-cis-trikentrin B,
(±)-herbindole A and (±)-herbindole B via intermolecular indole aryne cycloaddition are
described. The 5,6,7-tribromoindole was ...
Establishing Metronidazole as a Novel Biomarker of CYP2A6 Activity
(University of Missouri -- Kansas City, 2018)
CYP2A6 is a polymorphically expressed enzyme with variation associated with
smoking behavior, cessation success, lung cancer risk, and differential drug exposure to
numerous medications including anti-infectious and ...
