Insight into the siRNA transmembrane delivery-From cholesterol conjugating to tagging

Small interfering RNA (siRNA), combining the features of unprecedented potency, target-specificity, and the unique sequence-based disease-intervention model, has received immense considerations over the past decades in the academia and pharmaceutical industry. siRNA fits the criteria of being drug-likely enough to meet with the therapeutic purpose, but its clinical translation has been impeded for a long time by the poor efficiency of in vivo delivery. To reach the cytosol where the RNA interference (RNAi) takes place, siRNA delivery faces a serial of systemic and cellular barriers, especially the endosomal sequestration that would prevent the majority of siRNA from cytosol entry. Transmembrane delivery of siRNA represents a new avenue for efficient delivery by bypassing the endosomal pathway. This rationale is bolstered by the high efficiency of viral entry by membrane fusion, but rarely pursued by artificial siRNA delivery systems. Here, this article provides an opinion of transmembrane delivery by hydrophobic modulation of siRNA. We give a brief introduction of the current siRNA delivery modes, including the hydrophobic cholesterol siRNA conjugates. The cholesterol tagging technology is design on the rationale of hydrophobic siRNAs approach, but hydrophobic modulation throughout the whole siRNA backbone for efficient membrane fusion and transmembrane delivery. The challenge and potential of this technology for preclinical development are also discussed.

Synthesis of TiO2 nanoparticles by electrochemical method and their antibacterial application

Titanium dioxide nanoparticles were successfully prepared by electrochemical method. The tetra propyl ammonium bromide salt was used as stabilizing agent in an organic medium viz. tetra hydro furan (THF) and acetonitrile (ACN) in 4:1 ratio by optimizing current density. The parameters such as current density, solvent polarity, distance between electrodes and concentration of stabilizers were used to control the size of nanoparticles. The synthesized titanium dioxide nanoparticles were characterized by using UV-Visible spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), energy dispersive spectrophotometer (EDS) and transmission electron microscopy (TEM) analysis techniques. TEM analysis proved a nearly tetragonal structure with size of 25-30 nm which was in agreement with the result calculated from the XRD analysis. EDS analysis revealed the presence of Ti and O element. The nanoparticles were screened for their in vitro antibacterial activity against human pathogens such as gram negative Escherichia coli (E. coli), and gram positive Staphylococcus aureus strains and which proved excellent results.

Downregulation of microRNA let-7f mediated the Adriamycin resistance in leukemia cell line

Multidrug resistance (MDR) has become the major cause of failure chemotherapy for leukemia and high mortality of leukemia. The study aimed to investigate whether the let-7f mediate the Adriamycin (ADR) resistance of leukemia, and to explore the potential molecular mechanism. Cell proliferation was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and the soft agar clone formation assay. Flow cytometry was performed to detected cell cycle and apoptosis. The targeted regulationship was analyzed by dual-luciferase assay. Real-time polymerase chain reaction and Western blot were used to measure the expressions of let-7f, ABCC5, ABCC10, cell cycle-related proteins, and apoptosis-related proteins. The xenograft mouse model was used to conduct the tumor formation assay in vivo. The results demonstrated that the expression of let-7f was lower in multidrug-resistant K562/A02 cell lines compared to that in K562, while ABCC5 and ABCC10 were upregulated. Overexpression of let-7f in K562/A02 cell lines downregulated the ABCC5 and ABCC10 expression, enhanced cell sensitivity to ADR, promoted cell apoptosis, and inhibited cell proliferation. let-7f was proved to negatively regulate ABCC5 and ABCC10. Tumor formation assay further determined that let-7f overexpression increased sensitivity to ADR. Taken together, the let-7f downregulation induced the ADR resistance of leukemia by upregulating ABCC5 and ABCC10 expression. Our study provided a novel perspective to study the mechanism of MDR and a new target for the reversal of MDR.

lnc9141-a and -b Play a Different Role in Bovine Myoblast Proliferation, Apoptosis, and Differentiation

Previously, our transcriptome sequencing revealed that lnc9141 was differentially expressed in muscles of fetal bovine, calf, and adult bovine, which is considered to provide the basis for raising the muscle mass. In this study, we identified lnc9141 characters. lnc9141 has different transcription start sites and 30 alternative splicing sites of exon 1, producing lnc9141-a and lnc9141-b transcripts that were highly expressed in the heart and lung. Moreover, neither lnc9141-a nor lnc9141-b had the ability to encode proteins. The functions of lnc9141-a and lnc9141-b were explored by cell cycle, 5-ethynyl-2′-deoxyuridine (EdU), and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The results showed that lnc9141-a or lnc9141-b overexpression decreased the number of myoblasts in the S phase and increased the proportion of cells in the G0/G1 phase. Furthermore, overexpressing lnc9141-a and lnc9141-b respectively downregulated the expression of Cyclin D1. However, lnc9141-a or lnc9141-b interference was found to increase the number of S-phase myoblasts, and upregulate Cyclin D1 and Cyclin E expression. Through Annexin V-FITC/propidium iodide (PI) double staining and the expression of apoptosis marker genes (Bax, Bcl2, and Caspase-3), it was found that lnc9141-b could regulate the expression of Bax gene. Meantime, high expression of lnc9141-b could decrease MyHC expression. In addition, the intergenic region between lnc9141 and IRX5 was 2.3 kb, with a head-to-head orientation. The study also revealed the core regions of the lnc9141 and IRX5 promoter. Our study demonstrated that both lnc9141-a and -b expression inhibited bovine myoblast proliferation. However, lnc9141-b regulated Bax and MyHC expression. The regulatory mechanism of lnc9141-a and lnc9141-b needs to be further explored.

Efficient cleavage of tertiary amide bonds via radical-polar crossover using a copper(ii) bromide/Selectfluor hybrid system

A novel approach for the efficient cleavage of the amide bonds in tertiary amides is reported. Based on the selective radical abstraction of a benzylic hydrogen atom by a CuBr2/Selectfluor hybrid system followed by a selective cleavage of an N-C bond, an acyl fluoride intermediate is formed. This intermediate may then be derivatized in a one-pot fashion. The reaction proceeds under mild conditions and exhibits a broad substrate scope with respect to the tertiary amide moiety as well as to nitrogen, oxygen, and carbon nucleophiles for the subsequent derivatization. Mechanistic studies suggest that the present reaction proceeds via a radical-polar crossover process that involves benzylic carbon radicals generated by the selective radical abstraction of a benzylic hydrogen atom by the CuBr2/Selectfluor hybrid system. Furthermore, a synthetic application of this method for the selective cleavage of peptides is described.
