A multicompartmental model of vitamin A kinetics in rats with marginal liver vitamin A stores.

open access: yesJournal of Lipid Research, 1985
A linear, first-order, constant-coefficient multicompartmental model is presented which describes the dynamics of [3H]retinol turnover in adult rats with normal plasma retinol concentrations but low liver stores (less than 100 micrograms of retinol ...

Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis

open access: yesHepatology, EarlyView., 2022
Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis. Abstract Background and Aims Nucleotide‐binding oligomerization domain‐like receptor‐family pyrin domain‐containing 3 (NLRP3) inflammasome activation has been shown to result in liver fibrosis.

Confocal Raman imaging reveals the impact of retinoids on human breast cancer via monitoring the redox status of cytochrome c

open access: yesScientific Reports, 2023
This paper expands the current state of knowledge on impact of retinoids on redox status of cytochrome c in cancers. Little is known how the expression of cytochromes may influence the development of cancers.

CD8+ T cell memory is sustained in mice by hepatic stellate cells

open access: yesHepatology, EarlyView., 2022
HSC role in memory CD8+ T cell maintenance. Abstract Background and Aims Long‐lasting immunological memory is the ultimate goal of vaccination. Homeostatic maintenance of memory CD8+ cytotoxic T cells (MemCD8TCs) is thought to be mediated by IL‐15/IL‐15R heterodimer (15HD)‐expressing myeloid cells.

A Functional Binding Domain in the Rbpr2 Receptor Is Required for Vitamin A Transport, Ocular Retinoid Homeostasis, and Photoreceptor Cell Survival in Zebrafish

open access: yesCells, 2020
Dietary vitamin A/all-trans retinol/ROL plays a critical role in human vision. ROL circulates bound to the plasma retinol-binding protein (RBP4) as RBP4-ROL. In the eye, the STRA6 membrane receptor binds to circulatory RBP4 and internalizes ROL. STRA6 is,

Evidence for an Essential Role of Megalin in Transepithelial Transport of Retinol [PDF]

open access: yesJournal of the American Society of Nephrology, 1999
Abstract. Transepithelial transport of retinol is linked to retinol-binding protein (RBP), which is taken up and also synthesized in a number of epithelia. By immunocytochemistry of human, rat, and mouse renal proximal tubules, a strong staining in apical endocytic vacuoles, lysosomes, endoplasmic reticulum, Golgi, and basal ...

Retinol Esterification Activity Contributes to Retinol Transport in Stellate Cells.

open access: yesCell Structure and Function, 1999
The mechanisms of retinol transport and accumulation in hepatic stellate cells (HSC) remain to be elucidated. Our previous studies suggested that retinol esterification activity, particularly lecithin:retinol acyltransferase (LRAT) activity, in liver retinoid metabolism is important to elucidate the relationship between retinol uptake by HSC and the ...

Retinoid-binding proteins: similar protein architectures bind similar ligands via completely different ways. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Retinoids are a class of compounds that are chemically related to vitamin A, which is an essential nutrient that plays a key role in vision, cell growth and differentiation. In vivo, retinoids must bind with specific proteins to perform their
