Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh Jan 2023

Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh

Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …


Oleyl Conjugated Histidine-Arginine Cell-Penetrating Peptides As Promising Agents For Sirna Delivery, Muhammad Imran Sajid, Dindyal Mandal, Naglaa Salem El-Sayed, Sandeep Lohan, Jonathan Moreno, Rakesh Kumar Tiwari Apr 2022

Pharmacy Faculty Articles and Research

Recent approvals of siRNA-based products motivated the scientific community to explore siRNA as a treatment option for several intractable ailments, especially cancer. The success of approved siRNA therapy requires a suitable and safer drug delivery agent. Herein, we report a series of oleyl conjugated histidine–arginine peptides as a promising nonviral siRNA delivery tool. The conjugated peptides were found to bind with the siRNA at N/P ratio ≥ 2 and demonstrated complete protection for the siRNA from early enzymatic degradation at N/P ratio ≥ 20. Oleyl-conjugated peptide -siRNA complexes were found to be noncytotoxic in breast cancer cells (MCF-7 and MDA-MB-231) …


Novel Peptide Biomaterials For Enhanced Delivery Of Sirna Cargo For Treatment Of Ovarian Cancer, Timothy Samec Dec 2021

Novel Peptide Biomaterials For Enhanced Delivery Of Sirna Cargo For Treatment Of Ovarian Cancer, Timothy Samec

All Dissertations

Ovarian cancer is the 7th leading cause of cancer related death and the 5th most commonly diagnosed cancer among women. Primarily diagnosed in stage III or stage IV, aggressive treatment is necessary and involves surgical debulking and administration of systemic chemotherapeutics. Unfortunately, these strategies fall short in effectively treating ovarian cancer and many patients experience local disease recurrence, development of multidrug resistant tumors, regional or distant metastatic events, or a combination of the three. As such, there is a significant need for additional treatment options and methods of delivery to improve therapeutic efficacy and disease survivability.

Theranostic Applications Of Sirna Bioconjugates In Cancer Detection And Treatment, Sunil S. Shah May 2021

Theranostic Applications Of Sirna Bioconjugates In Cancer Detection And Treatment, Sunil S. Shah

Seton Hall University Dissertations and Theses (ETDs)

Abstract

The emerging field of RNA nanotechnology has led to rapid advances in the applications of RNA in chemical biology, medicinal chemistry, and biotechnology. At the forefront of its utility is the ability to self-assemble multiple siRNAs into nanostructure formulations capable of targeting selected oncogenes and potentiating the gene therapy of malignant tumors. Self-assembled siRNA integrates multiple siRNAs within a single molecular platform for silencing multiple oncogenic mRNA targets with high precision and efficacy to potentially induce cancer cell apoptosis through the RNA interference (RNAi) pathway. Furthermore, the conjugation of siRNA self-assemblies with bio-active probes results in multi-functional theranostic (therapy+diagnostic) …


A Robust Delivery System For Rna Therapeutics, Suleyman Bozal May 2019

A Robust Delivery System For Rna Therapeutics, Suleyman Bozal

University Scholar Projects

The field of RNA therapeutics is currently undergoing both transformation and expansion. Specifically, research in lipid nanoparticle (LNP) based RNA therapeutics is gaining significant traction. Other research into mechanisms of gene regulation and manipulation, including siRNA and the CRISPR/Cas9 system have demonstrated the potential of RNA-based disease treatment. This work identifies a delivery system which can regulate expression of green fluorescent protein (GFP) in human embryonic kidney cells (HEK293) stably expressing GFP.

Analysis of siRNA-induced gene knockdown demonstrates that the current siRNA-LNP formulation is equally as effective as a commercially available transfection reagent, Lipofectamine RNAiMAX (RNAiMAX), which is designed specifically …

Rna Nanotechnology For Next Generation Targeted Drug Delivery, Fengmei Pi

Theses and Dissertations--Pharmacy

The emerging field of RNA nanotechnology is developing into a promising platform for therapeutically application. Utilizing the state-of-art RNA nanotechnology, RNA nanoparticles can be designed and constructed with controllable shape, size for both RNA therapeutics and chemical drug delivery. The high homogeneity in particle size and ease for RNA therapeutic module conjugation, made it feasible to explore versatile RNA nanoparticle designs for preclinical studies.

One vital module for therapeutic RNA nanoparticle design is RNA aptamer, which can enable the RNA nanoparticles find its specific target for targeted drug delivery. A system of screening divalent RNA aptamers for cancer cell targeting …


Development Of Non-Covalent Functionalization Of Carbon Nanotubes For Sirna Delivery, King Sun Siu Apr 2014

Development Of Non-Covalent Functionalization Of Carbon Nanotubes For Sirna Delivery, King Sun Siu

Electronic Thesis and Dissertation Repository

RNA interference (RNAi) therapy is promising for treating various diseases but the delivery of small interfering RNA (siRNA) is difficult. To overcome the technical difficulties of siRNA delivery, an efficient and targeted delivery of siRNA is required for efficient RNAi therapy. Single-walled carbon nanotubes (CNT) has been used for nucleic acid delivery such as siRNA delivery. It has been found that CNT can gain entry into the cells by a diffusion-like mechanism which was called “nano-needle”. However, the solubility of CNT is low in most of the solvents including water. Functionalization of CNT can be carried out to enhance the …
