Gene therapy is one of the most promising medical fields with the potential to effectively advance the treatment of difficult diseases by producing therapeutic proteins or repairing defective gene sequences. However, gene therapy presents severe challenges in delivery including renal clearance, phagocytosis, enzymatic degradation, protein absorption, and cellular internalization barriers, which have been barriers for translation into the clinic. Naked nucleic acids, with their intrinsic negative charge, electrostatically repulse the anionic cell membrane, preventing cellular uptake. Also, they are considered foreign genetic material when introduced into the body and are rapidly cleared by the reticuloendothelial system or degraded by nucleases, …
Complexation Of Glycoalkaloid Α- Tomatine With Sterols And Its Potential Application As An Anti-Cancer Drug, Bishal Nepal
Complexation Of Glycoalkaloid Α- Tomatine With Sterols And Its Potential Application As An Anti-Cancer Drug, Bishal Nepal
Dissertations
Glycoalkaloids (GAs) are secondary metabolites found mostly in higher plant species and some marine invertebrates. They are known to form complexes with 3β-hydroxy sterols such as cholesterol causing membrane disruption. So far the visual evidence showcasing the complexes formed between glycoalkaloids and sterols has been mainly restricted to some earlier studies using Brewster angle microscopy. This study aimed to develop a method for topographic and morphological analysis of sterol-glycoalkaloid complexes. Langmuir-Blodgett (LB) transfer of monolayers comprising of glycoalkaloid tomatine, sterols, and lipids in varying molar ratios onto mica followed by AFM examination was performed. The AFM method used required minimal …

The studies presented in section 1 (Chapters I-IV) focus on the design and development of nucleic acid four-way junctions (4WJs) to target a member of the high mobility group (HMG) proteins, the proinflammatory cytokine high mobility group box 1 protein (HMGB1). In the present study, hybrid PNA-DNA 4WJs based on a model DNA 4WJ were constructed to improve the thermal stability of 4WJs while maintaining strong binding affinity toward HMGB1. An electrophoretic mobility shift assay (EMSA) was used to examine the binding affinity of an isolated DNA binding domain of HMGB1, the HMGB1 b-box (HMGB1b), toward a set of PNA-DNA …
