Osteoblast-targeting peptides in the treatment of bone disease is a new and novel approach to offering effective treatment of various cancers and can be used in bio-medical, medicinal chemistry and biotechnology applications. By targeting adhesion proteins produced by osteoblast cells, certain cancers which migrate and metastasize to the bone may be more effectively treated. An osteoblast-targeting peptide composed of Ser-Asp-Ser-Ser-Asp (SDSSD) which selectively binds to osteoblast cells via periostin has recently been identified. This peptide was functionalized with polyurethane, generating nanomicelles which encapsulated RNA for the therapeutic treatment of osteoporosis. This study has served as the basis for the research …

Researchers have begun investigating whether insulin mimetics such as ZnCl2 could promote bone healing in both non-diabetic and diabetic fracture healing similarly to insulin. Our research focused on understanding the mechanism by which ZnCl2 affects chondrogenesis, an important component of bone fracture healing. The increases in proteoglycan deposition and cell proliferation seen in our data may be a result of ZnCl2 induction of the IGF-1 pathway. When the VEGF pathway was inhibited in ZnCl2- or insulin-treated cells significant decreases in proteoglycan deposition occurred on day 7 and 14 (P=0.007 for ZnCl2, P=0.028 for insulin) when compared to controls. This data …

Fluorescently Labeled Sirnas And Their Theranostic Applications In Cancer Gene Therapy, Stephen David Kozuch

Gene therapy has emerged as a promising precision nano-medicine strategy in the treatment of numerous diseases including cancer. At the forefront of its utility are the applications of short-interfering RNA (siRNA), that silence oncogenic mRNA expression leading to cancer cell death through the RNA interference (RNAi) pathway. Despite the therapeutic potential, siRNAs are limited by poor pharmacological properties, which has hindered their translation into the clinic. Recent studies, however, have highlighted the applications of modified siRNAs, including the use of fluorescent probes and siRNA nanostructures in cancer detection and treatment. The siRNAs reported in this thesis are designed to target …

The killer peptide sequence D-(KLAKLAK)2 has been originally designed and developed as an antibacterial agent. Despite having excellent cytotoxicity towards bacteria, this sequence maintains low cell cytotoxity in malignant mammalian cell types such as cancer. The chemical basis for its selectivity has been attributed to its poly(cationic) amphiphilic nature, which facilitates cell permeability across the negatively charged bacterial membrane, but with limited permeability across the zwitterionic membrane of mammalian cells. The positively charged D-(KLAKLAK)2 sequence has been found to accumulate on the surface of the mitochondria causing dissipation of the negatively charged mitochondrial membrane potential. This charge disruption …
Morphine Enhances The Permeability Across Vascular Endothelial Cell Barriers, Jenine Anday
Morphine Enhances The Permeability Across Vascular Endothelial Cell Barriers, Jenine Anday

Using three types of in vitro endothelial cell barrier models, we investigated the direct effects and mechanisms of morphine on vascular permeability. Our current studies illustrate LPS induces permeability across these VEC barriers, and is significantly enhanced when co-treated with morphine, displayed using the [ 14 CJ-inulin paracellular marker. Incubation with morphine alone induces permeability in a concentration depeodent manner, and is not blocked by the addition of naloxone. Morphine enhances the detrimental effects of LPS on cell viability and alone also decreases endothelial cell viability, concentration-dependently, which is also not affected by naloxone, as demonstrated by the trypan blue …
