Among the first tissues to differentiate in the mammalian embryo are cardiac and subsequently skeletal striated muscle. We have developed specific cRNA probes corresponding to the 5' noncoding regions of alpha-cardiac and alpha-skeletal actin mRNAs in order to investigate myogenesis in the mouse embryo. Transcripts coding for cardiac actin which is the(More)
This paper reports the development of an enhanced chemiluminescent (ECL) assay for measuring the total antioxidant (AO) capacity of serum, saliva and a fluid collectable from the gum margin called gingival crevicular fluid (GCF). The theory behind the assay is explained, and the optimum conditions for the assay, and for storage of reagents and clinical(More)
Proximal upstream flanking sequences of the mouse myosin alkali light chain gene encoding MLC1F and MLC3F, the mouse alpha-cardiac actin gene and the chicken gene for the alpha-subunit of the acetylcholine receptor were linked to the bacterial chloramphenicol acetyl transferase (CAT) gene and transfected into primary cultures derived from mouse skeletal(More)
Myosin heavy chain (MHC) genes are expressed as several distinct isoforms in a tissue- and stage-specific manner; three skeletal muscle MHC isoforms appear sequentially during development. We have isolated cDNA clones, identified by RNA blot hybridization and by nucleotide sequence determination as coding for portions of the embryonic (pMHC2.2), perinatal(More)
Fibrinogen is a complex plasma protein composed of two each of three different polypeptide chains. We have targeted expression of r-human fibrinogen to the mammary gland of transgenic mice. Three expression cassettes, each containing the genomic sequence for one of the three human fibrinogen chains controlled by sheep whey protein beta-lactoglobulin(More)
A DNase I-hypersensitive site analysis of the 5'-flanking region of the mouse alpha-cardiac actin gene with muscle cell lines derived from C3H mice shows the presence of two such sites, at about -5 and -7 kb. When tested for activity in cultured cells with homologous and heterologous promoters, both sequences act as muscle-specific enhancers. Transcription(More)
We describe the generation of five sheep transgenic for a fusion of the ovine beta-lactoglobulin gene promotor to the human alpha 1-antitrypsin (h alpha 1AT) genomic sequences. Four of these animals are female and one male. Analysis of the expression of h alpha 1AT in the milk of three of these females shows that all express the human protein at levels(More)
In high-risk and complicated coronary intervention, the risk of acute closure is unpredictable. Thrombus and platelet deposition at the intervention site may also have further effects on subsequent restenosis. In vivo infusion of activated protein C has previously been shown to achieve potent anticoagulation without any haemostatic side effects. We now(More)
Mammalian cardiac muscle contains two myosin alkali light chains which are the major isoforms present in either atrial (MLC1A) or ventricular (MLC1V) muscle, and which are different from the fast skeletal muscle isoforms (MLC1F and MLC3F). The atrial isoform is also expressed in fetal skeletal and fetal ventricular muscle, where this isoform is also(More)
The development of cardiac hypertrophy secondary to pressure overload is accompanied by isoformic changes of contractile proteins such as myosin and actin. 35S-Labeled complementary RNA (cRNA) probes and in situ hybridization procedures were used for analysis of the regional distribution of newly formed transcripts from alpha-skeletal actin (alpha-sk-actin)(More)
