Abstract
The successful development of nonviral delivery systems for nucleic acids has been reported extensively over the past number of years. Among them, lipid-based nanoparticles (LNPs) represent the most advanced platform. This review provides an overview of the state-of-the-art in LNP technology, focusing on the delivery of a range of nucleic acids. Recent advances in the development of an efficient and safe lipid-based system are critically analyzed with a particular emphasis on the rationale behind the design of LNPs and on attempts to elucidate the resulting molecular assembly and structure, their interactions with cellular proteins and biodistribution. In addition, manufacturing methods including microfluidics and their potential to influence stability and scale-up are summarized.

Abstract
Polymer-based nanocarriers require extensive knowledge of their chemistries to learn functionalization strategies and understand the nature of interactions that they establish with biological entities. In this research, the poly (β-amino ester) (PβAE-447) was synthesized and characterized, aimed to identify the influence of some key parameters in the formulation process. Initially; PβAE-447 was characterized for aqueous solubility, swelling capacity, proton buffering ability, and cytotoxicity study before nanoparticles formulation. Interestingly, the polymer-supported higher cell viability than the Polyethylenimine (PEI) at 100 μg/ml. PβAE-447 complexed with GFP encoded plasmid DNA (pGFP) generated nanocarriers of 184 nm hydrodynamic radius (+7.42 mV Zeta potential) for cell transfection. Transfection assays performed with PEGylated and lyophilized PβAE-447/pDNA complexes on HEK-293, BEAS-2B, and A549 cell lines showed better transfection than PEI. The outcomes toward A549 cells (above 66%) showed the highest transfection efficiency compared to the other cell lines. Altogether, these results suggested that characterizing physicochemical properties pave the way to design a new generation of PβAE-447 for gene delivery.

Abstract
The elevation of intraocular pressure (IOP) is an important risk factor in the development of primary open angle glaucoma (POAG), which is the main cause of irreversible vision loss. miRNAs are promising new anti-glaucoma therapeutic agents. However, the low stability and cellular transfection of miRNA in vivo hinder its further application. This study aims to investigate the use of polydopamine-polyethylenimine nanoparticles (PDA/PEI NPs) as miRNA carriers in the treatment of ocular hypertension and glaucoma. The in vitro study proves that the carrier preserves the activity of nucleic acid for a long period. Besides, it has comparable transfection efficiency with commercially available vehicles, while having lower cytotoxicity. It has been demonstrated in the animal model that PDA/PEI NPs successfully reach the target tissues without an obvious inflammatory response. PDA/PEI NPs/miR-21-5p increases the permeability of porcine angular aqueous plexus cells, thereby reducing IOP by facilitating the conventional outflow pathway at least partially through the pathway involving endothelial nitric oxide synthase. Our results indicate that PDA/PEI NPs/miR-21-5p is a promising anti-glaucoma drug for treating POAG. And the delivery strategy may be extended to other gene therapy in treating intraocular diseases.

pH-triggered release of manganese from MnAu nanoparticles that enables cellular neuronal differentiation without cellular toxicity. Biomaterials 2015; 55:33-43.

Abstract
At high concentrations, manganese (Mn) promotes cellular neurodevelopment but causes toxicity. Here, we report that Mn ion at high concentrations can be delivered to pheochromocytoma 12 (PC12) cells using gold nanoparticles (AuNPs) to enhance cellular neurodevelopment without toxicity. Mn(2+) release from AuNPs was designed to be pH-responsive so that low pH condition of the cell endosomes can trigger in situ release of Mn(2+) from AuNPs after cellular uptake of Mn-incorporated AuNPs (MnAuNPs). Due to the differences in reduction potentials of Mn and Au, only Mn ionized and released while Au remained intact when MnAuNPs were uptaken by cells. Compared to PC12 cells treated with a high concentration of free Mn(2+), PC12 cells treated with an equal concentration of MnAuNPs resulted in significantly enhanced cellular neurodevelopment with decreased apoptosis and necrosis. Treatment with a high concentration of free Mn(2+) led to an abrupt consumption of a large amount of ATP for the intracellular transport of Mn(2+) through the ion channel of the cell membrane and to mitochondrial damage caused by the high intracellular concentration of Mn(2+), both of which resulted in cell necrosis and apoptosis. In contrast, MnAuNP-treated cells consumed much smaller amount of ATP for the intracellular transport of MnAuNPs by endocytosis and showed pH-triggered in situ release of Mn(2+) from the MnAuNPs in the endosomes of the cells, both of which prevented the cell death caused by ATP depletion and mitochondrial damage. To our knowledge, this is the first report on the use of AuNPs as a vehicle for pH-responsive, intracellular delivery of metal ion, which may open a new window for drug delivery and clinical therapy.

Abstract
Radionuclide-based theranostic strategy has been widely used in diagnosis and treatment of patients with hyperthyroidism or differentiated thyroid cancer for a long time, and sodium iodide symporter gene is the radionuclide-based reporter gene used in theranostics. Theranostics, which is a promising approach, offering the ideal combination of accurate diagnosis and successful therapy in various clinical fields, is expected to become a key area of personalized medicine. Rapid advancements in biotechnologies using theranostic reporter genes and theranostic radiochemistry have led to development of the concept of theranostics using radionuclide-based imaging reporter genes; the theranostic approach is almost ready for application in a limited arena of clinics. In order to fulfill both the diagnostic and therapeutic purposes, theranostics with radionuclide-based imaging reporter requires use of successful combinations of various components, such as radionuclide-based reporter genes, promoters/enhancers that regulate expression of reporter genes, delivery vectors/vehicles, imaging or therapeutic probes and prodrugs, transductional and transcriptional targeting strategies, transgene amplification systems, etc. In this review, overview and recent updates on theranostics using radionuclide-based imaging reporter genes will be discussed.
