Fluidity of Thyroid Plasma Membranes

1988
The main function of the thyroid cell is the secretion of thyroid hormones (T4, thyroxine; T3, triiodothyronine). Thyroid hormones are first synthesized as part of thyroglobulin. Newly synthesized thyroglobulin is iodinated and vectorially transported to the apical region of the cell and released for storage in the lumen by exocytosis.

Steroids decrease granulocyte membrane fluidity, while phorbol ester increases membrane fluidity

Inflammation, 1990
High concentrations of corticosteroids inhibit granulocyte responses and disrupt agonist receptor function. Dose-response and time-course considerations make it unlikely that these effects are mediated via the glucocorticoid receptor, a concept further supported by the ability of sex steroids to work similar effects.

Membrane Fluidity and Cancer Metastasis

Pathobiology, 1989
The membrane fluidity of murine B16 melanoma and L5178 lymphoma variants is examined in relation to their metastatic potential. A higher lateral mobility of membrane proteins in metastasis is indicated by lectin receptor-mediated agglutination studies, but these do not constitute incontrovertible evidence that higher fluidity might be relevant in the ...

Membrane fluidity sensoring microbial fuel cell

Bioelectrochemistry, 2003
A study has been performed to examine the effect of temperature and ethanolic stresses on the coulombic efficiency of a microbial fuel cell. The conventional-type fuel cell containing Gram-negative bacteria, Proteus vulgaris, was investigated as a model system.

Cell membrane fluidity and prostaglandins

Medical Hypotheses, 1981
Abstract It is proposed that prostaglandins may bring about some of their actions by altering cell membrane fluidity.

β-amyloid peptide decreases membrane fluidity

Brain Research, 1995
The beta-amyloid peptide-25-35 (beta A25-35) decreases the fluidity of mouse brain membranes in a concentration-depending fashion. First effects were already seen at a beta A25-35 concentration of 100 nmol/1. beta-Amyloid peptide(1-40) was similarly active.

Erythrocyte membrane fluidity in malignant hyperthermia

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1991
Malignant hyperthermia (MH) is a rare but serious complication of general anesthesia that potentially carries a high mortality and morbidity. It is associated with excessive release of calcium into skeletal muscle following exposure to certain drugs, including the volatile general anesthetics.

Membrane fluidity and bile salt damage

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1981
The lysis, by bile salts, of membranes of different fluidities was studied; it was shown that membranes of low fluidity were less readily lysed than membranes of higher fluidity. Membrane fluidity levels were controlled (i) by the use of erythrocytes, from different species, systematically differing in their lipid composition; (ii) by using each ...

Membrane Fluidity and Cellular Functions

1975
An area of intense current interest in molecular and cell biology is the structure of biological membranes. A great change in our picture of membranes has occurred in the last few years, and there is now fairly widespread acceptance of a model for the organization of the lipids and proteins of membranes called the “fluid mosaic model” (Singer and ...

Adenylate cyclase and membrane fluidity

Molecular and Cellular Biochemistry, 1984
The relationships between membrane fluidity as induced by drug addition and the stimulation of adenylate cyclase by hormones (mainly catecholamines), GTP, Gpp(NH)p and NaF are reviewed. In particular, the data corresponding to pigeon erythrocyte membranes are reviewed and compared with other data published in the literature.
