The nucleic acid changes during embryonic development have been stucliecl by several investigators (l-4). It is now generally agreed that a rapidly growing tissue has a high concentration of nucleic acid (5). Thus, in the avian embryo, the concentrations of pentose nucleic acid (PNA) and clesoxypentose nucleic acid (DNA) increase during the time of the most rapid growth of the tissue (6, 7). Si...
Low-molecular-weight RNA from transforming viruses (Rous sarcoma virus-Rous-associated virus 1, Schmidt-Ruppin strain of Rous sarcoma virus, and sarcoma-B(77)), from nontransforming viruses (Rous-associated virus 1 and sarcoma-NTB(77)), and from chicken liver, chicken embryo fibroblast, and Rous sarcoma virus-Rous-associated virus 1-transformed chicken embryo fibroblast was isolated and purifie...
UDP-Glucuronyltransferase (GT) activity increases in chick embryo liver during culture from zero to a steady-state level at or above adult values. The GT activity (o-aminophenol as acceptor) is located entirely in the membranes of the endoplasmic reticulum (ER) and the question arises whether ER increases along with GT. Earlier work showed that the synthesis and degradation rates of GT can be v...
1. Tissue-specific profiles of the expression of the antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) and the concentrations of reduced glutathione (GSH) during the development of the chick embryo were investigated. 2. The liver, brain, yolk sac membrane (YSM), kidney, lung, heart and skeletal muscles were collected at the following days of embr...
In the developing fetal liver of many animals, the appearance of glycogen in quantities demonstrable by classical chemical methods is a relatively tardy and abrupt event. For example, using Sahyun and Alsberg’s (1) modification of Pfliiger’s technique, Hard et al. (2) have shown in the guinea pig that there is no detectable liver glycogen up to the 56th day of gestation (term 66 days) but that ...
background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...
The anti-hypercholesterolemic effect of berbamine (BBM) isolated from Rhizoma Coptidis (RC) was investigated in hypercholesterolemic zebrafish model induced by high-cholesterol (HC) diet. Zebrafish embryo assay revealed no significant difference in morphology and cell death with the treatment of BBM less than 20 μg/mL. In zebrafish larvae, the fluorescently labeled cholesterol in caudal artery ...
Liver cell supernatant and platelet extract can promote the in vivo growth of herpes simplex virus type 2-transformed hamster embryo fibroblast cells. Delineation of necessary growth factors for tumor cells in vivo may open up new strategies to inhibit malignant cell growth.
