Abstract
Introducing functional macromolecules into a variety of living cells is challenging but important for biology research and cell-based therapies. We report a novel cell delivery platform based on rotating shape anisotropic magnetic particles (SAMPs), which make very small cuts on cell membranes for macromolecule delivery with high efficiency and high survivability. SAMP delivery is performed by placing commercially available nickel powder onto cells grown in standard cell culture dishes. Application of a uniform magnetic field causes the magnetic particles to rotate because of mechanical torques induced by shape anisotropic magnetization. Cells touching these rotating particles are nicked, which generates transient membrane pores that enable the delivery of macromolecules into the cytosol of cells. Calcein dye, 3 and 40 kDa dextran polymers, a green fluorescence protein (GFP) plasmid, siRNA, and an enzyme (β-lactamase) were successfully delivered into HeLa cells, primary normal human dermal fibroblasts (NHDFs), and mouse cortical neurons that can be difficult to transfect. The SAMP approach offers several advantages, including easy implementation, low cost, high throughput, and efficient delivery of a broad range of macromolecules. Collectively, SAMP delivery has great potential for a broad range of academic and industrial applications.

Abstract
Combination of chemotherapeutic drug and small interfering RNA (siRNA) can affect multiple disease pathways and has been proven effective in suppressing tumor progression. Co-delivery of drug and siRNA within a same nanocarrier is a vital means in this field. The present study aimed at the development of a pH-sensitive liposome to co-deliver drug and siRNA to tumor region. Driven by the electrostatic interaction, the pH-sensitive material, carboxymethyl chitosan (CMCS), was coated onto the surface of the cationic liposome (CL) preloaded with sorafenib (Sf) and siRNA (Si). To evaluate whether the resulting CMCS-modified Sf and siRNA co-delivery cationic liposome (CMCS-SiSf-CL) enhanced antitumor efficiency after systematic administration, in vitro and in vivo experiments were evaluated in HepG2 cells and the H22 cells-bearing Kunming mice model. The experimental results demonstrated that CMCS-SiSf-CL was able to condense siRNA efficiently and protect siRNA from being degraded by serum and RNase. The release rate of Sf from CMCS-modified liposome exhibited pH-sensitive release behavior. Furthermore, in vitro cellular uptake results showed that CMCS-SiSf-CL yielded higher fluorescence intensity at pH 6.5 than at pH 7.4, and that siRNA could be delivered to tumor site by CMCS-SiSf-CL in vivo. The in vivo antitumor efficacy showed that CMCS-Sf-CL inhibits tumor growth effectively when compared with free Sf solution. In current experimental conditions, this liposomal formulation did not show significant toxicity both in vitro and in vivo. Therefore, co-delivering Sf with siRNA by CMCS-SiSf-CL might provide a promising approach for tumor therapy.

siRNA Versus miRNA as Therapeutics for Gene Silencing. MOLECULAR THERAPY. NUCLEIC ACIDS 2015; 4:e252.

Abstract
Discovered a little over two decades ago, small interfering RNAs (siRNAs) and microRNAs (miRNAs) are noncoding RNAs with important roles in gene regulation. They have recently been investigated as novel classes of therapeutic agents for the treatment of a wide range of disorders including cancers and infections. Clinical trials of siRNA- and miRNA-based drugs have already been initiated. siRNAs and miRNAs share many similarities, both are short duplex RNA molecules that exert gene silencing effects at the post-transcriptional level by targeting messenger RNA (mRNA), yet their mechanisms of action and clinical applications are distinct. The major difference between siRNAs and miRNAs is that the former are highly specific with only one mRNA target, whereas the latter have multiple targets. The therapeutic approaches of siRNAs and miRNAs are therefore very different. Hence, this review provides a comparison between therapeutic siRNAs and miRNAs in terms of their mechanisms of action, physicochemical properties, delivery, and clinical applications. Moreover, the challenges in developing both classes of RNA as therapeutics are also discussed.

Abstract
Complex biological barriers are major obstacles for preventing and treating disease. Nanocarriers are designed to overcome such obstacles by enhancing drug delivery through physiochemical barriers and improving therapeutic indices. This review critically examines both biological barriers and nanocarrier payloads for a variety of drug delivery applications. A spectrum of nanocarriers is discussed that have been successfully developed for improving tissue penetration for preventing or treating a range of infectious, inflammatory, and degenerative diseases.
