Liposomal delivery of alpha-Interferon to murine bladder tumor cells via transferrin receptor-mediated endocytosis.

Drug delivery

Liao WP, DeHaven J, Shao J, Chen JX, Rojanasakul Y, Lamm DL, Ma JK.
PMID: 19570002
Drug Deliv. 1998;5(2):111-8. doi: 10.3109/10717549809031386.

The role of transferrin receptor-mediated endocytosis in promoting murine bladder tumor cell (MBT2) uptake of liposomes and the antiproliferative effect of liposome-entrapped alpha-interferon (alpha-IFN) against MBT2 were investigated. Liposomes (0.11 microm) were prepared using phosphatidylcholine and phosphatidylserine in a...

Abnormal staggerer cerebellar cell interactions and survival in vitro.

Neuroscience letters

Messer A.
PMID: 19605215
Neurosci Lett. 1978 Sep;9(2):185-8. doi: 10.1016/0304-3940(78)90069-1.

Staggerer cerebellar cells in primary monolayer cell culture exhibit less initial clumping and unexpectedly longer overall survival than their wild-type counterparts when grown in medium containing fetal calf serum. Although polylysine coating of substratum both reduces the amount of...

A dual-beam optical microscope for observation and cleavage of single DNA molecules.

Analytical chemistry

Lyon WA, Fang MM, Haskins WE, Nie S.
PMID: 21651268
Anal Chem. 1998 May 01;70(9):1743-8. doi: 10.1021/ac980040+.

An integrated epifocal and evanescent-wave optical microscope has been developed for real-time observation and bond cleavage studies of single DNA molecules. Large genomic DNA is stretched in a laminar flow stream and is immobilized on a polylysine-coated glass surface...

Naphthalene sulfonate functionalized dendrimers at the solid-liquid interface: influence of core type, ionic strength, and competitive ionic adsorbates.

Langmuir : the ACS journal of surfaces and colloids

Barnes TJ, Ametov I, Prestidge CA.
PMID: 18834156
Langmuir. 2008 Nov 04;24(21):12398-404. doi: 10.1021/la8020996. Epub 2008 Oct 04.

The adsorption of naphthalene disulfonic acid surface-functionalized dendrimers (generation 4) on to colloidal alumina particles is reported, considering the role of dendrimer core type (ammonia vs benzylhydrylamine-polylysine) and electrolyte addition on the adsorption affinity and interfacial packing and competitive...

The reaction of rat mast cells to polylysine.

The Journal of cell biology

Padawer J.
PMID: 19866736
J Cell Biol. 1970 Nov 01;47(2):352-72. doi: 10.1083/jcb.47.2.352.

The effects of a single intraperitoneal injection of polyamino acids (lysine, glutamic, aspartic) on mast cells of the rat are described. In vitro interaction of mast-cell components with these polyamino acids is also explored. Poly-DL-lysine (but not the acidic...

Protected Graft Copolymer (PGC) in Imaging and Therapy: A Platform for the Delivery of Covalently and Non-Covalently Bound Drugs.

Theranostics

Bogdanov AA, Mazzanti M, Castillo G, Bolotin E.
PMID: 22737192
Theranostics. 2012;2(6):553-76. doi: 10.7150/thno.4070. Epub 2012 Jun 04.

Initially developed in 1992 as an MR imaging agent, the family of protected graft copolymers (PGC) is based on a conjugate of polylysine backbone to which methoxypoly(ethylene glycol) (MPEG) chains are covalently linked in a random fasion via N-ε-amino...

Methods for Gene Transfer Using DNA-Adenovirus Conjugates.

Methods in molecular medicine

Curiel DT.
PMID: 24493415
Methods Mol Med. 1997;7:1-23. doi: 10.1385/0-89603-484-4:1.

Strategies have been developed to accomplish gene delivery via the receptor-mediated pathway employing molecular conjugate vectors (1-13). As cells possess endogenous pathways for internalization of macromolecules, the utilization of these pathways for the purpose of DNA delivery represents a...

Antimicrobial packaging based on ɛ-polylysine bioactive film for the control of mycotoxigenic fungi in vitro and in bread.

Journal of food processing and preservation

Luz C, Calpe J, Saladino F, Luciano FB, Fernandez-Franzón M, Mañes J, Meca G.
PMID: 29456275

ɛ-Poly-l-lysine (ɛ-PL) is a cationic peptide with a broad-spectrum antimicrobial activity. This study investigates the use of ɛ-PL as natural antimicrobial to inhibit fungal growth and to reduce aflatoxins (AFs) production. Antifungal activity of starch biofilms with different concentrations...

Targeted transplantation of mitochondria to hepatocytes.

Hepatic medicine : evidence and research

Gupta N, Wu CH, Wu GY.
PMID: 27942238
Hepat Med. 2016 Nov 29;8:115-134. doi: 10.2147/HMER.S116852. eCollection 2016.

BACKGROUND: Mitochondrial defects in hepatocytes can result in liver dysfunction and death. Hepatocytes have cell-surface asialoglycoprotein receptors (AsGRs) which internalize AsGs within endosomes. The aim of this study was to determine whether mitochondria could be targeted to hepatocytes by...
