Binding of Cationic α-Helical Peptides to Plasmid DNA and Their Gene Transfer Abilities into Cells*
Polycationic reagents such as cationic lipids and poly-l-lysine are widely used for gene transfer into cells in vitro and show promise as vectors for in vivo gene therapy applications as nonviralExpand
Importance of hydrophobic region in amphiphilic structures of alpha-helical peptides for their gene transfer-ability into cells.
It has been showned that cationic alpha-helical peptides can be useful as nucleic acid-carrier molecules for gene transfer into cells. In order to investigate the significancemake sure of importanceExpand
Interaction of lipophilic peptides derived from mastoparan with phospholipid vesicles.
Various kinds of lipophilic peptides were prepared by acylation of an alpha-helical peptide, mastoparan, to investigate the effects of acyl groups on the interaction of peptides with phospholipidExpand
Interaction of alpha-helical peptides with phospholipid membrane: effects of chain length and hydrophobicity of peptides.
To investigate the interaction of amphiphilic alpha-helical peptides with phospholipid membranes, we synthesized Ac-(Leu-Ala-Arg-Leu)3-NHCH3 (4[3]) and three derivatives, in which the chain lengthExpand
Experimental and clinical significance of antinuclear antibodies in liver transplantation.
Histone H1 and high-mobility group box 1 (HMGB1) proteins are known to initiate an immune reaction, and the corresponding antibodies (Abs) possess immunosuppressive activity. In the present study, weExpand
Membrane interaction of synthetic peptides related to the putative fusogenic region of PH-30 alpha, a protein in sperm-egg fusion.
In order to investigate the relationship between structure and function of a putative fusogenic region of PH-30a, a protein active in sperm-egg fusion, two peptides, SFP22 and SFP23, whose sequencesExpand
Antitumor effects of the MIG and IP-10 genes transferred with poly [D,L-2,4-diaminobutyric acid] on murine neuroblastoma
The number of tumor-infiltrating lymphocytes is known to be related to outcomes in patients with a variety of malignancies. Interferon (IFN) γ-inducible protein-10 (IP-10) and monokine induced byExpand
Dendritic cell immunotherapy with poly(d,l‐2,4‐diaminobutyric acid)‐mediated intratumoral delivery of the interleukin‐12 gene suppresses tumor growth significantly
A conventional DC‐based immunotherapy has been tested clinically for treatment of patients with advanced cancer but requires modification to further improve the clinical results. In this study, weExpand
Chain Length of Cationic α-Helical Peptide Sufficient for Gene Delivery into Cells
To define the minimal peptide length needed for gene delivery into mammalian cells, we synthesized several peptides with shortened chain lengths from the amino-termini of the original amphiphilicExpand
Influence of lipophilic groups in cationic alpha-helical peptides on their abilities to bind with DNA and deliver genes into cells.
For the purpose of achieving gene transfer into cells mediated by peptides with a short chain length, we employed two kinds of amphiphilic alpha-helix peptides, mastoparan (INLK-ALAA-LAKK-IL-NH2)Expand
