Nearly one out of six deaths in 2020, around ten million people, were caused by cancer, making it a leading cause of death worldwide (WHO, 2022). This major public health issue, in addition to the rise of multidrug-resistant (MDR) pathogens, provides a high demand for the discovery of new pharmaceutical drugs to be used clinically to treat these conditions. The Streptomyces genus accounts to produce 39% of all microbial metabolites currently approved for human health, indicating its potential as an important species to study for antimicrobial and anticancer agents. The long linear genome of Streptomyces contains specialized sequences known as …

Arts & Sciences Electronic Theses and Dissertations
Ultraviolet light is well known to induce cyclobutane pyrimidine dimers (CPD) and pyrimidine (6–4) pyrimidone photoproducts in duplex DNA, which interfere with DNA replication and transcription. Recently, a new class of DNA photoproducts known as anti cyclobutanepyrimidine dimers have been discovered, which form in G-quadruplex forming sequences in solution. G-quadruplex structures have been proposed to form in human DNA telomeres and certain promoters in vivo but evidence for their existence has been lacking. Since anti-cyclobutante pyrimidine dimers have been shown to form in G-quadruplex forming sequences, their formation in irradiated human cells could be used to confirm the existence …
Chemoenzymatic Studies To Enhance The Chemical Space Of Natural Products, Jhong-Min Chen
Chemoenzymatic Studies To Enhance The Chemical Space Of Natural Products, Jhong-Min Chen
Theses and Dissertations--Pharmacy
Natural products provide some of the most potent anticancer agents and offer a template for new drug design or improvement with the advantage of an enormous chemical space. The overall goal of this thesis research is to enhance the chemical space of two natural products in order to generate novel drugs with better in vivo bioactivities than the original natural products.
Polycarcin V (PV) is a gilvocarcin-type antitumor agent with similar structure and comparable bioactivity with the principle compound of this group, gilvocarcin V (GV). Modest modifications of the polyketide-derived tetracyclic core of GV had been accomplished, but the most …
Androgen Receptor-Dependent Effects Of Resveratrol On Tnsin Mrna Levels In Prostate Cancer Cells, Courtney Pisano
Androgen Receptor-Dependent Effects Of Resveratrol On Tnsin Mrna Levels In Prostate Cancer Cells, Courtney Pisano
PCOM Biomedical Studies Student Scholarship
The chemopreventive effects of resveratrol (RSV) on cancers, including prostate cancer, have been well documented; but the mechanisms are not well known. It has been reported recently that tensin, a matrix-adhesion protein, which is greatly down-regulated in prostate cancer, has been induced by RSV in several cancer cell lines. In order to know if RSV up-regulates tensin in prostate cells, we first treated LNCaP cells with RSV and demonstrated that tensin mRNA levels were upregulated by RSV in a time and dose dependent manner. Since LNCaP cells are androgen receptor (AR) positive and previous findings have shown that RSV down-regulates …
