TLDR
Results show that Tat-BMPs-PAMAM, with its targeted delivery and transmembrane ability, may be a novel gene delivery system with potential applications in the targeted gene therapy of brain tumors.
Abstract
Han and colleagues engineer an existing nonviral biocarrier based on polyamidoamine dendrimers to deliver an interfering RNA to downregulate expression of the oncogenic epidermal growth factor receptor in gliomas. To enable cell targeting and entry, and eventual transduction, portions of the HIV-1 Tat protein and magnetic nanoparticle technology were incorporated in the design.

Cell-penetrating peptides: breaking through to the other side

TL;DR: The rationales for the design of 'smart' pharmaceutical nanocarriers in which the cell-penetrating properties are hidden until triggered by exposure to appropriate environmental conditions (e.g., a particular pH, temperature, or enzyme level) are discussed.
Journal ArticleDOI

Surface-engineered dendrimers in gene delivery.

TL;DR: The results allowed us to assess the importance of knowing the carrier and removal status of canine coronavirus, as a source of infection for other animals, not necessarily belonging to the same breeds.

Efficient and targeted delivery of siRNA in vivo.

TL;DR: Major challenges in achieving efficient siRNA delivery in vivo are introduced and recent advances in overcoming them are discussed using chemically modified siRNA, viral siRNA vectors and nonviral siRNA carriers.

Magnetically enhanced nucleic acid delivery. Ten years of magnetofection—Progress and prospects

TL;DR: This review discusses magnetic formulations of vectors for nucleic acid delivery and their characterization, mechanisms of magnetofection, and the application of magnet ofection in viral and nonviral nucleic acids delivery in cell culture and in animal models.

Gene delivery using dendrimer-entrapped gold nanoparticles as nonviral vectors.

TL;DR: A new gene delivery vector based on dendrimer-entrapped gold nanoparticles (Au DENPs) with significantly higher gene transfection efficiency than that of dendricers without AuNPs entrapped is reported.

Tat peptide-derivatized magnetic nanoparticles allow in vivo tracking and recovery of progenitor cells.

TL;DR: A cell labeling approach using short HIV-Tat peptides to derivatize superparamagnetic nanoparticles is developed, which efficiently internalized into hematopoietic and neural progenitor cells in quantities up to 10–30 pg of super paramagnetic iron per cell.

The EGF receptor family as targets for cancer therapy.

TL;DR: The role of these active anti-receptor agents in the treatment of patients with cancer is addressed and compounds that directly inhibit receptor tyrosine kinases have shown preclinical activity and early clinical activity has been reported.

Chemotherapy in adult high-grade glioma: a systematic review and meta-analysis of individual patient data from 12 randomised trials.

TL;DR: A small but clear improvement in survival from chemotherapy is shown, which encourages further study of drug treatment of these tumours.

High-efficiency intracellular magnetic labeling with novel superparamagnetic-Tat peptide conjugates.

TL;DR: A biocompatible, dextran coated superparamagnetic iron oxide particle was derivatized with a peptide sequence from the HIV-tat protein to improve intracellular magnetic labeling of different target cells, and internalized into lymphocytes over 100-fold more efficiently than nonmodified particles.
