The Fate of Dna-containing Particles Phagocytized by Mammalian Cells
نویسندگان
چکیده
Particulate DNA protein coacervates were digested immediately after being phagocytized by L strain fibroblasts in suspension culture. Enlargement of the phagocytotic vacuoles occurred simultaneously with a loss of the electron opacity of the phagocytized particles. Cytochemical reactions positive for non-specific esterase, acid phosphatase, and nucleoside phosphatase in the phagocytotic vacuoles provided additional evidence for the probability of complete hydrolysis of the phagocytized nucleoprotein.

Perspectives on the mechanism of nickel carcinogenesis gained from models of in vitro carcinogenesis.
This article briefly reviews the approach taken to understand the mechanism of nickel-induced neoplastic transformation. The initial phases of the studies were focused on particulate nickel compounds and on the regulation of phagocytosis of nickel compounds by cells undergoing transformation. The particulate nickel compounds most potent in inducing cell transformation were selectively phagocyti...

The present study was conducted in order to investigate the pharmacological activities of three heterobimetallic coordination compounds: [Cd(N-bishydeten)2][Ni(CN)4] (C1), [Cu2(N-bishydeten)2Co(CN)6].3H2O (C2), and K[Cd(N-bishydeten)Co(CN)6].1.5H2O (C3) (N-bishydeten = N,N-bis(2-hydroxyethyl)-ethylenediamine). This paper describes the ability of complexes to inhibit cell growth, cell migration ...
متن کاملExpression of S and pre s2 Hepatitis B Surface Antigens in Mammalian Cos-7 Cell Line
Hepatitis B virus (HBV) is a serious global health problem. The development of a safe and effective vaccinewould help infection prevention. Previous hepatitis B vaccine production involved the isolation of the noninfectious particle from chronic HBV carriers. DNA recombinant technology has been used for vaccineproduction without having been contaminated with blood-born infectious ag...

متن کاملThe Interaction of Cationic Liposomes Containing Entrapped Horseradish Peroxidase with Cells in Culture
Cationic liposomes composed of sphingomyelin, cholesterol, and stearylamine were prepared with horseradish peroxidase trapped inside. Stable particles were formed in which 10-12% of the enzymic activity appeared to be located at, or near, the outer surface of the liposome. Adsorption and uptake of liposomes by HeLa cells were followed cytochemically by electron microscopy and quantitated by enz...
