Two types of glomus cell in the rat carotid body as revealed by α-bungarotoxin binding

Horseradish peroxidase (HRP)-conjugated α-bungarotoxin (αBgt) was used to localize αBgt-acetylcholine receptor sites in the rat carotid body. Two types of glomus cell were differentiated on the basis of the st...

Cell injury of cultured rat myocardial cells after reoxygenation of hypoxic cultures in the presence and absence of calcium

Primary cultures of rat myocytes were deprived of oxygen (approximately 5 mm Hg, pO₂) for 2 h in the presence or absence of calcium and were subsequently incubated for different time periods under normoxic (appro...

Dopamine β-hydroxylase-like immunoreactivity in the rat and cat carotid body: a light and electron microscopic study

Immunocytochemical localization of dopamine β-hydroxylase (DBH) was used to study the synthesis and storage sites of norepinephrine (noradrenaline) in the rat and cat carotid bodies. In the rat carotid body so...

Transferrin is a major mouse milk protein and is synthesized by mammary epithelial cells

We have identified a major mouse milk protein as transferrin (Tf) using immunoprecipitation, 2-dimensional electrophoresis, Ouchterlony diffusion and V-8 protease digests. We show that Tf is synthesized by mam...

Synthesis of laminin-related polypeptides in oocytes, eggs and early embryos of the amphibian Pleurodeles waltlii

In the amphibian Pleurodeles waltlii, lamininrelated polypeptides (amphibian-LN) are present in the extracellular matrix underlying the blastocoel roof of gastrulating embryos. Immunoprecipitation with affinity-p...

Establishment and characterization of a continuous murine uterine cervix cancer cell line metastatic to lymph nodes and lungs

The murine uterine cervix cancer (MUCC) cell line was derived from a chemically induced Kunming mouse uterine cervix cancer (U27) and maintained in culture on solid substrates for over 100 passages. Cultures w...

Altered low density lipoprotein receptor regulation is associated with cholesteryl ester accumulation in simian virus 40 transformed rodent fibroblast cell lines

Several SV40 transformed REF52 cell lines were found to accumulate 5 to 10 times more cholesteryl esters compared to their parent line REF52 when cultured in 10% serum. Under this culture condition, the choles...

Inversely related evolution of growth hormone and prolactin secretions in long-term tissue cultures of human pituitary adenomas from acromegalic patients

Pituitary tumoral tissue from 20 acromegalic patients was cultured for up to 120 d in a medium containing 5 nM cortisol. In all cultures, growth hormone (GH) release decreased. At the beginning of the culture, pr...
