Abstract
Nanoparticles (NPs) formulated with cationic lipids and/or polymers have shown substantial potential for systemic delivery of RNA therapeutics such as small interfering RNA (siRNA) for the treatment of cancer and other diseases. While both cationic lipids and polymers have demonstrated the promise to facilitate siRNA encapsulation and endosomal escape, they could also hamper cytosolic siRNA release due to charge interaction and induce potential toxicities. Herein, a unique polymer-prodrug hybrid NP platform was developed for multistage siRNA delivery and combination cancer therapy. This NP system is composed of (i) a hydrophilic polyethylene glycol (PEG) shell, (ii) a hydrophobic NP core made with a tumor microenvironment (TME) pH-responsive polymer, and (iii) charge-mediated complexes of siRNA and amphiphilic cationic mitoxantrone (MTO)-based prodrug that are encapsulated in the NP core. After intravenous administration, the long-circulating NPs accumulate in tumor tissues and then rapidly release the siRNA-prodrug complexes via TME pH-mediated NP disassociation for subsequent tissue penetration and cytosolic transport. With the overexpressed esterase in tumor cells to hydrolyze the amphiphilic structure of the prodrug and thereby induce destabilization of the siRNA-prodrug complexes, the therapeutic siRNA and anticancer drug MTO can be efficiently released in the cytoplasm, ultimately leading to the combinational inhibition of tumor growth via concurrent RNAi-mediated gene silencing and MTO-mediated chemotherapy.

Abstract
Prostatic diseases are a common health problem among males in Western countries, and include chronic prostatic diseases, which have an unclear pathogenesis and few treatment options. In vitro and in vivo studies describe oxidative stress as a major pathway involved in the occurrence of benign prostatic hyperplasia, prostatic cancer and chronic prostatitis. Thus, the oxidative stress cascade is a potential target for the treatment of prostatic diseases. This paper presents a systematic review of the available data concerning the association between oxidative stress and the most common chronic prostatic diseases, and describes the available treatment options that act upon this pathway.

Horizontal alignment of 5' -> 3' intergene distance segment tropy with respect to the gene as the conserved basis for DNA transcription. Future Sci OA 2017; 3:FSO160. [PMID: 28344824 PMCID: PMC5351715 DOI: 10.4155/fsoa-2016-0070] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2016] [Accepted: 10/31/2016] [Indexed: 01/31/2023] Open
Abstract
AIM To study the conserved basis for gene expression in comparative cell types at opposite ends of the cell pressuromodulation spectrum, the lymphatic endothelial cell and the blood microvascular capillary endothelial cell. METHODS The mechanism for gene expression is studied in terms of the 5' -> 3' direction paired point tropy quotients (prpTQs) and the final 5' -> 3' direction episodic sub-episode block sums split-integrated weighted average-averaged gene overexpression tropy quotient (esebssiwaagoTQ). RESULTS The final 5' -> 3' esebssiwaagoTQ classifies an lymphatic endothelial cell overexpressed gene as a supra-pressuromodulated gene (esebssiwaagoTQ ≥ 0.25 < 0.75) every time and classifies a blood microvascular capillary endothelial cell overexpressed gene every time as an infra-pressuromodulated gene (esebssiwaagoTQ < 0.25) (100% sensitivity; 100% specificity). CONCLUSION Horizontal alignment of 5' -> 3' intergene distance segment tropy wrt the gene is the basis for DNA transcription in the pressuromodulated state.
