Dysregulation of lipid metabolism in PLHC-1 and ZFL cells exposed to tributyltin an all-trans retinoic acid

All-trans Retinoic Acid Regulates the Balance of Treg-Th17 Cells through ERK and P38 Signaling Pathway

All-trans-retinoic acid: measurement

A quantitative determination of physiological levels of all-trans-retinoic acid (vitamin A acid) in human serum has been developed. A double-phase extraction of 3.5 ml of serum followed by a specific and sensitive high performance liquid chromatography procedure allowed measurement of levels down to 1 ng/ml. Serum concentrations in 37 fasting volunteers ranged from 2.7 to 4.2 ng/ml and fitted a...

Prophylactic effect of all-trans retinoic acid in an amyloid-beta rat model of Alzheimer\'s disease

Introduction: Retinoid signaling has been argued to have favorable effects on Alzheimer's disease (AD). We studied the role of chronic intracerebroventricular (ICV) injection of all-trans retinoic acid (ATRA) on the amyloid-beta (Aβ) model of AD. Methods: Adult male rats weighing 260-330 g were divided into 12 groups of 8 each. Six groups of rats received ATRA (3nM, 30nM, 3μM, 0.3mM, 30...

All-trans-retinoic acid and bleeding/thrombosis.

Hematology-Oncology Department Ospedali Riuniti Largo Barozzi, 1 24128 Bergamo (Italy) Tel. 39 035 269492, Fax 39 035 266659 E-Mail [email protected] All-trans-retinoic acid (ATRA) inhibits cell growth and proliferation by inducing cyto-differentiation and/or apoptosis in several cell types. These effects have become a therapeutic objective in human cancers. In addition to these functions, ...

Retinol inhibits the growth of all-trans-retinoic acid-sensitive and all-trans-retinoic acid-resistant colon cancer cells through a retinoic acid receptor-independent mechanism.

Retinol (vitamin A) is thought to exert its effects through the actions of its metabolite, all-trans-retinoic acid (ATRA), on gene transcription mediated by retinoic acid receptors (RAR) and retinoic acid response elements (RARE). However, retinoic acid resistance limits the chemotherapeutic potential of ATRA. We examined the ability of retinol to inhibit the growth of ATRA-sensitive (HCT-15) a...
