Stearylated arginine-rich peptides: a new class of transfection systems.

TLDR
In the case of the Tat, FHV, and octaarginine peptides, N-terminal stearylation of the peptides increases the transfection efficiency by approximately 100 times to reach the same order of magnitude as that of LipofectAMINE, one of the most efficient commercially available transfections agents.

Nonviral Vectors for Gene Delivery

TL;DR: Two nonviral gene delivery systems using either biodegradable poly(D,Llactide-co-glycolide) (PLG) nanoparticles or cell penetrating peptide (CPP) complexes have been designed and studied using A549 human lung epithelial cells.

Uptake Pathways and Subsequent Intracellular Trafficking in Nonviral Gene Delivery

TL;DR: The different uptake pathways that are involved in nonviral gene delivery from a gene delivery point of view are reviewed and available knowledge concerning cellular entry and the intracellular trafficking of cationic lipid-DNA complexes (lipoplexes) and cationsic polymer- DNA complexes (polyplexes) is summarized.

Cell-Penetrating Peptides : Design, Synthesis, and Applications

TL;DR: The intrinsic property of cell-penetrating peptides to deliver therapeutic molecules to cells and tissues in a nontoxic manner has indicated that they may be potential components of future drugs and disease diagnostic agents.

Rapid colorimetric assay for cellular growth and survival: Application to proliferation and cytotoxicity assays

TL;DR: A tetrazolium salt has been used to develop a quantitative colorimetric assay for mammalian cell survival and proliferation and is used to measure proliferative lymphokines, mitogen stimulations and complement-mediated lysis.

A truncated HIV-1 Tat protein basic domain rapidly translocates through the plasma membrane and accumulates in the cell nucleus

TL;DR: The main determinants required for Tat translocation within this sequence are delineated by synthesizing several peptides covering the Tat domain from residues 37 to 60 and the domain extending from amino acid 37 to 47, which corresponds to the α-helix structure, is not required for cellular uptake and for nuclear translocation.

The third helix of the Antennapedia homeodomain translocates through biological membranes

TL;DR: It is reported here that a polypeptide of 16 amino acids in length corresponding to the third helix of the homeodomain deleted of its N-terminal glutamate is still capable of translocating through the membrane, suggesting an energy-independent mechanism of translocation not involving classical endocytosis.

Arginine-rich Peptides: AN ABUNDANT SOURCE OF MEMBRANE-PERMEABLE PEPTIDES HAVING POTENTIAL AS CARRIERS FOR INTRACELLULAR PROTEIN DELIVERY *

TL;DR: Based on the fluorescence microscopic observations of mouse macrophage RAW264.7 cells, it is found that various arginine-rich peptides have a translocation activity very similar to Tat-(48–60), and the results strongly suggested the possible existence of a common internalization mechanism ubiquitous to arkinine- rich peptides.

Cell Internalization of the Third Helix of the Antennapedia Homeodomain Is Receptor-independent

TL;DR: The present demonstration, that a reverse helix and a helix composed of D-enantiomers still translocate across biological membranes at 4 and 37°C strongly suggests that the third helix of the homeodomain is internalized by a receptor-independent mechanism.
