Compartmentalized Production of Ceramide at the Cell Surface [PDF]
Journal of Biological Chemistry, 1995 Ceramide produced by the hydrolysis of sphingomyelin is an important cellular intermediate in hormone action. Here, we present evidence that interleukin 1 beta (IL-1 beta) binding to normal human fibroblasts initiates a lipid messenger cascade that takes place in a sphingomyelin-rich plasma membrane domain with the characteristics of caveolae.

Modulation in Wistar rats of blood corticosterone compartmentation by sex and a cafeteria diet. [PDF]
PLoS ONE, 2013 In the metabolic syndrome, glucocorticoid activity is increased, but circulating levels show little change. Most of blood glucocorticoids are bound to corticosteroid-binding globulin (CBG), which liver expression and circulating levels are higher in ...

Spermatogenesis and sertoli cell activity in mice lacking Sertoli cell receptors for follicle stimulating hormone and androgen [PDF]
, 2008 Spermatogenesis in the adult male depends on the action of FSH and androgen. Ablation of either hormone has deleterious effects on Sertoli cell function and the progression of germ cells through spermatogenesis.

Abscisic acid dynamics in roots detected with genetically encoded FRET sensors
eLife, 2014 Cytosolic hormone levels must be tightly controlled at the level of influx, efflux, synthesis, degradation and compartmentation. To determine ABA dynamics at the single cell level, FRET sensors (ABACUS) covering a range ∼0.2–800 µM were engineered using ...

The Phenylpropanoid Case – It Is Transport That Matters
Frontiers in Plant Science, 2018 Phenylpropanoids fulfill numerous physiological functions, essential for plant growth and development, as well as plant–environment interactions. Over the last few decades, many studies have shown that exquisite regulatory mechanisms at multiple levels ...

Ultrastructural Alterations in Cells of Sunflower Linear Glandular Trichomes during Maturation
Plants, 2021 Sunflower and related taxa are known to possess a characteristic type of multicellular uniseriate trichome which produces sesquiterpenes and flavonoids of yet unknown function for this plant. Contrary to the metabolic profile, the cytological development

SENIEUR status of the originating cell donor negates certain ‘anti-immunosenescence’ effects of ebselen and N-acetyl cysteine in human T cell clone cultures [PDF]
, 2014 Background: Damage to T cells of the immune system by reactive oxygen species may result in altered cell function or cell death and thereby potentially impact upon the efficacy of a subsequent immune response.

Functional compartmentalization and metabolic separation in a prokaryotic cell [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance In a typical prokaryotic cell, hundreds of metabolites are present and interconverted simultaneously, some serving as allosteric regulators for unrelated reactions or accidental substrates for promiscuous enzymes or being downright reactive and toxic.
